Column Linking
--------------

To add a spreadsheet feature we created LindedColumnActivity objects to allow
the user to pull in columns from other worksheets.  These columns will not only
display the contents of the source column, but the values will be factored
into the average for the worksheet where the linked column activity lives.

There are two types of linked activities, a link to an other worksheet's
activity, or a link to the average column of the worksheet.  Activity links
will use the score system of the source activity whereas worksheet average
links will use an assumed 100 point system.

Import helper to print the gradebook:

    >>> from schooltool.gradebook.browser.ftests import printGradebook

Log in as manager:

    >>> manager = Browser('manager', 'schooltool')

Now, set up a school year (2005-2006) with two terms (Fall and
Spring):

    >>> from schooltool.app.browser.ftests import setup
    >>> setup.setUpBasicSchool()

Set up two courses:

    >>> setup.addCourse('Physics I', '2005-2006')
    >>> setup.addCourse('Math I', '2005-2006')

Set up persons:

    >>> from schooltool.basicperson.browser.ftests.setup import addPerson
    >>> addPerson('Paul', 'Carduner', 'paul', 'pwd', browser=manager)
    >>> addPerson('Tom', 'Hoffman', 'tom', 'pwd', browser=manager)
    >>> addPerson('Claudia', 'Richter', 'claudia', 'pwd', browser=manager)
    >>> addPerson('Stephan', 'Richter', 'stephan', 'pwd', browser=manager)

Set up one section with instructor and students for each term:

    >>> setup.addSection('Math I', '2005-2006', 'Fall',
    ...                  instructors=['Stephan'],
    ...                  members=['Tom', 'Claudia', 'Paul'])
    >>> setup.addSection('Physics I', '2005-2006', 'Spring',
    ...                  instructors=['Stephan'],
    ...                  members=['Tom', 'Claudia', 'Paul'])

Set up the default category for activities:

    >>> manager.getLink('Manage').click()
    >>> manager.getLink('Activity Categories').click()
    >>> manager.getControl('Default Category').displayValue = ['Journal']
    >>> manager.getControl('Change').click()

Log in as teacher:

    >>> stephan = Browser('stephan', 'pwd')

Add a couple of activities to the default worksheet:

    >>> stephan.getLink('Gradebook').click()
    >>> stephan.printQuery('//select[@name="currentTerm"]/option[@selected="selected"]/text()')
    2005-2006 / Fall
    >>> stephan.printQuery('//select[@name="currentSection"]/option[@selected="selected"]/text()')
    Math I - Math I (1)
    >>> stephan.getLink('New Activity').click()
    >>> stephan.getControl('Title').value = 'HW 1'
    >>> stephan.getControl('Description').value = 'Homework 1'
    >>> stephan.getControl('Category').displayValue = ['Assignment']
    >>> stephan.getControl('Maximum').value = '50'
    >>> stephan.getControl('Add').click()

    >>> stephan.getLink('New Activity').click()
    >>> stephan.getControl('Title').value = 'Quiz'
    >>> stephan.getControl('Description').value = 'Week 1 Pop Quiz'
    >>> stephan.getControl('Category').displayValue = ['Exam']
    >>> stephan.getControl('Add').click()

Add some grades:

    >>> stephan.getControl(name='Activity_paul').value = '40'
    >>> stephan.getControl(name='Activity_tom').value = '48'
    >>> stephan.getControl(name='Activity_claudia').value = '45'

    >>> stephan.getControl(name='Activity-2_paul').value = '90'
    >>> stephan.getControl(name='Activity-2_tom').value = '88'
    >>> stephan.getControl(name='Activity-2_claudia').value = '29'

    >>> stephan.getControl('Save').click()

Check the totals and averages:

    >>> printGradebook(stephan.contents)
    +----------+
    | *Sheet1* |
    +----------+
    +-----------------+-------+-------+---------+---------+
    | Name            | Total | Ave.  | HW1     | Quiz    |
    +-----------------+-------+-------+---------+---------+
    | Paul Carduner   | 130.0 | 86.7% | [40___] | [90___] |
    | Tom Hoffman     | 136.0 | 90.7% | [48___] | [88___] |
    | Claudia Richter | 74.0  | 49.3% | [45___] | [29___] |
    +-----------------+-------+-------+---------+---------+

We'll add another worksheet:

    >>> stephan.getLink('Worksheets').click()
    >>> stephan.getLink('New Worksheet').click()
    >>> stephan.getControl('Title').value = 'Second Sheet'
    >>> stephan.getControl('Add').click()

Let's add some activities, weighting and grades to the new worksheet:

    >>> stephan.getLink('Return to Gradebook').click()
    >>> stephan.getLink('Second Sheet').click()
    >>> stephan.printQuery('//select[@name="currentTerm"]/option[@selected="selected"]/text()')
    2005-2006 / Fall
    >>> stephan.printQuery('//select[@name="currentSection"]/option[@selected="selected"]/text()')
    Math I - Math I (1)
    >>> printGradebook(stephan.contents)
    +--------+----------------+
    | Sheet1 | *Second Sheet* |
    +--------+----------------+
    +-----------------+-------+------+
    | Name            | Total | Ave. |
    +-----------------+-------+------+
    | Paul Carduner   | 0.0   | N/A  |
    | Tom Hoffman     | 0.0   | N/A  |
    | Claudia Richter | 0.0   | N/A  |
    +-----------------+-------+------+

    >>> stephan.getLink('New Activity').click()
    >>> stephan.getControl('Title').value = 'First Homework'
    >>> stephan.getControl('Label').value = '1st HW'
    >>> stephan.getControl('Category').displayValue = ['Homework']
    >>> stephan.getControl('Add').click()

    >>> stephan.getLink('New Activity').click()
    >>> stephan.getControl('Title').value = 'First Presentation'
    >>> stephan.getControl('Label').value = '1st Presentation'
    >>> stephan.getControl('Category').displayValue = ['Presentation']
    >>> stephan.getControl('Add').click()

    >>> stephan.getLink('New Activity').click()
    >>> stephan.getControl('Title').value = 'Second Presentation'
    >>> stephan.getControl('Label').value = '2nd Presentation'
    >>> stephan.getControl('Category').displayValue = ['Presentation']
    >>> stephan.getControl('Add').click()

    >>> stephan.getLink('Weight Categories').click()
    >>> stephan.getControl('Homework').value = '25'
    >>> stephan.getControl('Presentation').value = '75'
    >>> stephan.getControl('Update').click()

    >>> stephan.getLink('1stHW').click()
    >>> stephan.getControl('Paul Carduner').value = u'70'
    >>> stephan.getControl('Tom Hoffman').value = u'75'
    >>> stephan.getControl('Claudia Richter').value = u'85'
    >>> stephan.getControl('Save').click()

    >>> stephan.getLink('1stPr').click()
    >>> stephan.getControl('Paul Carduner').value = u'84'
    >>> stephan.getControl('Tom Hoffman').value = u'73'
    >>> stephan.getControl('Claudia Richter').value = u'67'
    >>> stephan.getControl('Save').click()

    >>> stephan.getLink('2ndPr').click()
    >>> stephan.getControl('Paul Carduner').value = u'72'
    >>> stephan.getControl('Tom Hoffman').value = u'81'
    >>> stephan.getControl('Claudia Richter').value = u'89'
    >>> stephan.getControl('Save').click()

Check the total and averages for this worksheet:

    >>> printGradebook(stephan.contents)
    +--------+----------------+
    | Sheet1 | *Second Sheet* |
    +--------+----------------+
    +-----------------+-------+-------+---------+---------+---------+
    | Name            | Total | Ave.  | 1stHW   | 1stPr   | 2ndPr   |
    +-----------------+-------+-------+---------+---------+---------+
    | Paul Carduner   | 226.0 | 76.0% | [70___] | [84___] | [72___] |
    | Tom Hoffman     | 229.0 | 76.5% | [75___] | [73___] | [81___] |
    | Claudia Richter | 241.0 | 79.8% | [85___] | [67___] | [89___] |
    +-----------------+-------+-------+---------+---------+---------+

We'll switch to the Spring term and add some activities and scores to
the Physics I section:

    >>> stephan.getControl(name='currentTerm').displayValue = ['2005-2006 / Spring']
    >>> stephan.getForm().submit()
    >>> stephan.getLink('New Activity').click()
    >>> stephan.getControl('Title').value = 'Lab 1'
    >>> stephan.getControl('Description').value = 'Laboratory 1'
    >>> stephan.getControl('Category').displayValue = ['Assignment']
    >>> stephan.getControl('Maximum').value = '99'
    >>> stephan.getControl('Add').click()

    >>> stephan.getLink('New Activity').click()
    >>> stephan.getControl('Title').value = 'Final'
    >>> stephan.getControl('Description').value = 'Final Exam'
    >>> stephan.getControl('Category').displayValue = ['Exam']
    >>> stephan.getControl('Add').click()

    >>> stephan.getLink('Lab1').click()
    >>> stephan.getControl('Paul Carduner').value = u'89'
    >>> stephan.getControl('Tom Hoffman').value = u'72'
    >>> stephan.getControl('Claudia Richter').value = u'91'
    >>> stephan.getControl('Save').click()

    >>> stephan.getLink('Final').click()
    >>> stephan.getControl('Paul Carduner').value = u'99'
    >>> stephan.getControl('Tom Hoffman').value = u'88'
    >>> stephan.getControl('Claudia Richter').value = u'89'
    >>> stephan.getControl('Save').click()

We'll test the totals and averages so that we can check the linked
values later:

    >>> printGradebook(stephan.contents)
    +----------+
    | *Sheet1* |
    +----------+
    +-----------------+-------+-------+---------+---------+
    | Name            | Total | Ave.  | Lab1    | Final   |
    +-----------------+-------+-------+---------+---------+
    | Paul Carduner   | 188.0 | 94.5% | [89___] | [99___] |
    | Tom Hoffman     | 160.0 | 80.4% | [72___] | [88___] |
    | Claudia Richter | 180.0 | 90.5% | [91___] | [89___] |
    +-----------------+-------+-------+---------+---------+

Now we'll return to the Fall Math I section and add our first linked
column to the Sheet1 worksheet. We'll also test the Cancel button in
the New Linked Column form:

    >>> stephan.getControl(name='currentTerm').displayValue = ['2005-2006 / Fall']
    >>> stephan.getForm().submit()
    >>> stephan.getLink('Sheet1').click()
    >>> printGradebook(stephan.contents)
    +----------+--------------+
    | *Sheet1* | Second Sheet |
    +----------+--------------+
    +-----------------+-------+-------+---------+---------+
    | Name            | Total | Ave.  | HW1     | Quiz    |
    +-----------------+-------+-------+---------+---------+
    | Paul Carduner   | 130.0 | 86.7% | [40___] | [90___] |
    | Tom Hoffman     | 136.0 | 90.7% | [48___] | [88___] |
    | Claudia Richter | 74.0  | 49.3% | [45___] | [29___] |
    +-----------------+-------+-------+---------+---------+

    >>> stephan.getLink('New Linked Column').click()
    >>> stephan.printQuery('//h1/text()')
    Add Linked Column
    >>> stephan.getControl('Cancel').click()

First we'll test the contents of the form and the table of available
activities and worksheet averages that can be chosen as the link:

    >>> stephan.getLink('New Linked Column').click()
    >>> stephan.printQuery('//h1/text()')
    Add Linked Column

    >>> stephan.printQuery('//input[@name="title"]')
    <input type="text" name="title" id="title" value="" />
    >>> stephan.printQuery('//input[@name="label"]')
    <input type="text" name="label" id="label" value="" />
    >>> stephan.printQuery('id("category")/option/text()')
    Assignment
    Essay
    Exam
    Homework
    Journal
    Lab
    Presentation
    Project
    >>> stephan.printQuery('id("category")/option[@selected="selected"]/text()')
    Journal

    >>> stephan.printQuery('//table[@class="schooltool_gradebook"]/tr/*[1]/text()')
    Term
    Fall
    Spring
    >>> stephan.printQuery('//table[@class="schooltool_gradebook"]/tr/*[2]/text()')
    Section
    Math I (1)
    Physics I (1)
    >>> stephan.printQuery('//table[@class="schooltool_gradebook"]/tr/*[3]/text()')
    Worksheet
    Second Sheet
    Sheet1
    >>> stephan.printQuery('//table[@class="schooltool_gradebook"]/tr/th[4]/text()')
    Activity
    >>> stephan.printQuery('//table[@class="schooltool_gradebook"]/tr/td[4]/input/@value')
    First Homework
    First Presentation
    Second Presentation
    Average
    Lab 1
    Final
    Average

We'll add a link to the Second Presentation from the Second Sheet and
then we'll test that the category for our new linked column has been
saved correctly:

    >>> stephan.getControl('Category').displayValue = ['Essay']
    >>> stephan.getControl('Second Presentation').click()
    >>> stephan.getLink('Manage Worksheet').click()
    >>> stephan.getLink('Second Presentation').click()
    >>> stephan.printQuery('id("category")/option[@selected="selected"]/text()')
    Essay
    >>> stephan.getControl('Cancel').click()
    
then the average of the worksheet from the Spring Physics I section,
Sheet1:

    >>> stephan.getLink('New Linked Column').click()
    >>> stephan.getControl('Category').displayValue = ['Assignment']
    >>> stephan.getControl('Label').value = 'PHSICS'
    >>> stephan.getControl('Average', index=1).click()

We made a mistake in the label of the linked column, let's go change
it from the Manage Worksheet view:

    >>> stephan.getLink('Manage Worksheet').click()
    >>> stephan.getLink('Sheet1').click()
    >>> stephan.printQuery('id("category")/option[@selected="selected"]/text()')
    Assignment
    >>> stephan.getControl('Label').value = 'PHYSICS'
    >>> stephan.getControl('Average', index=1).click()

The worksheet now has two new columns whose values are pulled in from
the sources of the links.

    >>> printGradebook(stephan.contents)
    +----------+--------------+
    | *Sheet1* | Second Sheet |
    +----------+--------------+
    +-----------------+-------+-------+---------+---------+-------+-------+
    | Name            | Total | Ave.  | HW1     | Quiz    | 2ndPr | PHYSI |
    +-----------------+-------+-------+---------+---------+-------+-------+
    | Paul Carduner   | 296.5 | 84.7% | [40___] | [90___] | 72    | 94.5  |
    | Tom Hoffman     | 297.4 | 85.0% | [48___] | [88___] | 81    | 80.4  |
    | Claudia Richter | 253.5 | 72.4% | [45___] | [29___] | 89    | 90.5  |
    +-----------------+-------+-------+---------+---------+-------+-------+

What happens if the value of the source of a linked column
change. Let's change the grade for Paul's Second Presentation of the
Second Sheet:

    >>> stephan.getLink('Second Sheet').click()
    >>> stephan.getLink('2ndPr').click()
    >>> stephan.getControl('Paul Carduner').value = '99'
    >>> stephan.getControl('Save').click()

And let's change a grade for Tom in the Spring Physics I section so
his average also changes:

    >>> stephan.getControl(name='currentTerm').displayValue = ['2005-2006 / Spring']
    >>> stephan.getForm().submit()
    >>> stephan.getLink('Final').click()
    >>> stephan.getControl('Tom Hoffman').value = u'60'
    >>> stephan.getControl('Save').click()
    >>> printGradebook(stephan.contents)
    +----------+
    | *Sheet1* |
    +----------+
    +-----------------+-------+-------+---------+---------+
    | Name            | Total | Ave.  | Lab1    | Final   |
    +-----------------+-------+-------+---------+---------+
    | Paul Carduner   | 188.0 | 94.5% | [89___] | [99___] |
    | Tom Hoffman     | 132.0 | 66.3% | [72___] | [60___] |
    | Claudia Richter | 180.0 | 90.5% | [91___] | [89___] |
    +-----------------+-------+-------+---------+---------+

The linked columns should also change:

    >>> stephan.getControl(name='currentTerm').displayValue = ['2005-2006 / Fall']
    >>> stephan.getForm().submit()
    >>> stephan.getLink('Sheet1').click()
    >>> printGradebook(stephan.contents)
    +----------+--------------+
    | *Sheet1* | Second Sheet |
    +----------+--------------+
    +-----------------+-------+-------+---------+---------+-------+-------+
    | Name            | Total | Ave.  | HW1     | Quiz    | 2ndPr | PHYSI |
    +-----------------+-------+-------+---------+---------+-------+-------+
    | Paul Carduner   | 323.5 | 92.4% | [40___] | [90___] | 99    | 94.5  |
    | Tom Hoffman     | 283.3 | 81.0% | [48___] | [88___] | 81    | 66.3  |
    | Claudia Richter | 253.5 | 72.4% | [45___] | [29___] | 89    | 90.5  |
    +-----------------+-------+-------+---------+---------+-------+-------+

We can grade student by student, we'll see no linked columns there.

    >>> stephan.getLink('>', index=0).click()
    >>> stephan.printQuery('//h3/text()')
    Enter grades for Paul Carduner

    >>> stephan.printQuery('//label/span/text()')
    HW 1 (50)
    Quiz (100)

    >>> stephan.printQuery('//div[@class="widget"]/*')
    <input id="form-widgets-Activity"... value="40" type="text" />
    <input id="form-widgets-Activity-2"... value="90" type="text" />

Now, let's go back to the Physics I section of the Spring and delete
all grades for Paul, so he will have no average for that worksheet:

    >>> stephan.getControl('Cancel').click()
    >>> stephan.getControl(name='currentTerm').displayValue = ['2005-2006 / Spring']
    >>> stephan.getForm().submit()

    >>> stephan.getLink('>', index=0).click()
    >>> stephan.getControl('Lab 1').value = ''
    >>> stephan.getControl('Final').value = ''
    >>> stephan.getControl('Apply').click()

Let's go back to the Math I section of the Fall and check the grades for Paul:

    >>> stephan.getControl(name='currentTerm').displayValue = ['2005-2006 / Fall']
    >>> stephan.getForm().submit()
    >>> stephan.getLink('>', index=0).click()
    >>> stephan.printQuery('//h3/text()')
    Enter grades for Paul Carduner
    >>> stephan.printQuery('//label/span/text()')
    HW 1 (50)
    Quiz (100)

    >>> stephan.printQuery('//div[@class="widget"]/*')
    <input id="form-widgets-Activity"... value="40" type="text" />
    <input id="form-widgets-Activity-2"... value="90" type="text" />

Now, we're going to delete the source of a linked column. Let's delete
the 2nd Presentation activity of the Second Sheet worksheet, leaving
the 2nd Presentation linked column of Sheet1 with no source:

    >>> stephan.getControl('Cancel').click()
    >>> stephan.getLink('Second Sheet').click()
    >>> stephan.getLink('Manage Worksheet').click()
    >>> stephan.getControl(name='delete:list').value = ['Activity-3']
    >>> stephan.getControl('Delete').click()
    >>> stephan.getLink('Return to Gradebook').click()
    >>> printGradebook(stephan.contents)
    +--------+----------------+
    | Sheet1 | *Second Sheet* |
    +--------+----------------+
    +-----------------+-------+-------+---------+---------+
    | Name            | Total | Ave.  | 1stHW   | 1stPr   |
    +-----------------+-------+-------+---------+---------+
    | Paul Carduner   | 154.0 | 80.5% | [70___] | [84___] |
    | Tom Hoffman     | 148.0 | 73.5% | [75___] | [73___] |
    | Claudia Richter | 152.0 | 71.5% | [85___] | [67___] |
    +-----------------+-------+-------+---------+---------+

Now, when we get back to Sheet1, the linked column should have
disappeared:

    >>> stephan.getLink('Sheet1').click()
    >>> printGradebook(stephan.contents)
    +----------+--------------+
    | *Sheet1* | Second Sheet |
    +----------+--------------+
    +-----------------+-------+-------+---------+---------+-------+
    | Name            | Total | Ave.  | HW1     | Quiz    | PHYSI |
    +-----------------+-------+-------+---------+---------+-------+
    | Paul Carduner   | 130.0 | 86.7% | [40___] | [90___] |       |
    | Tom Hoffman     | 202.3 | 80.9% | [48___] | [88___] | 66.3  |
    | Claudia Richter | 164.5 | 65.8% | [45___] | [29___] | 90.5  |
    +-----------------+-------+-------+---------+---------+-------+

Same if we grade a student:

    >>> stephan.getLink('>', index=0).click()
    >>> stephan.printQuery('//h3/text()')
    Enter grades for Paul Carduner
    >>> stephan.printQuery('//label/span/text()')
    HW 1 (50)
    Quiz (100)

    >>> stephan.printQuery('//div[@class="widget"]/*')
    <input id="form-widgets-Activity"... value="40" type="text" />
    <input id="form-widgets-Activity-2"... value="90" type="text" />

Deletion should also work with columns linked to the average of a
worksheet. It's not possible to delete worksheets, but we can hide
them. Let's hide the Sheet1 worksheet of the Physics Spring section:

    >>> stephan.getControl('Cancel').click()
    >>> stephan.getControl(name='currentTerm').displayValue = ['2005-2006 / Spring']
    >>> stephan.getForm().submit()

    >>> stephan.getLink('Worksheets').click()
    >>> stephan.getControl(name='hide:list').value = ['Worksheet']
    >>> stephan.getControl('Hide').click()

    >>> # XXX: Hack to get back to the other term,
    >>> #      hiding all the worksheets in a gradebook
    >>> #      makes this impossible, because the Term and Section
    >>> #      dropdowns are not shown
    >>> stephan.getLink('Home').click()
    >>> stephan.getLink('Math I -- Math I (1)').click()
    >>> stephan.getLink('Gradebook', index=1).click()

We're back to the Sheet1 worksheet of the Math Fall section:

    >>> stephan.printQuery('//select[@name="currentTerm"]/option[@selected="selected"]/text()')
    2005-2006 / Fall
    >>> stephan.printQuery('//select[@name="currentSection"]/option[@selected="selected"]/text()')
    Math I - Math I (1)
    >>> printGradebook(stephan.contents)
    +----------+--------------+
    | *Sheet1* | Second Sheet |
    +----------+--------------+
    +-----------------+-------+-------+---------+---------+
    | Name            | Total | Ave.  | HW1     | Quiz    |
    +-----------------+-------+-------+---------+---------+
    | Paul Carduner   | 130.0 | 86.7% | [40___] | [90___] |
    | Tom Hoffman     | 136.0 | 90.7% | [48___] | [88___] |
    | Claudia Richter | 74.0  | 49.3% | [45___] | [29___] |
    +-----------------+-------+-------+---------+---------+

If we unhide the worksheet:

    >>> # XXX: Hack to unhide the only worksheet in the gradebook
    >>> #      the Unhide button is not shown when all the worksheets
    >>> #      have been hidden in a gradebook
    >>> stephan.getControl(name='currentTerm').displayValue = ['2005-2006 / Spring']
    >>> stephan.getForm().submit()
    >>> stephan.getLink('Worksheets').click()
    >>> stephan.getLink('Unhide Worksheets').click()
    >>> url = stephan.url
    >>> stephan.open(url + '?UNHIDE=True&unhide:list=Worksheet')
    >>> stephan.getLink('Return to Gradebook').click()

the linked column is shown again:

    >>> stephan.getControl(name='currentTerm').displayValue = ['2005-2006 / Fall']
    >>> stephan.getForm().submit()

    >>> printGradebook(stephan.contents)
    +----------+--------------+
    | *Sheet1* | Second Sheet |
    +----------+--------------+
    +-----------------+-------+-------+---------+---------+-------+
    | Name            | Total | Ave.  | HW1     | Quiz    | PHYSI |
