True
The checkbox widget works with Bool fields:
>>> field = Bool(__name__='foo', title=u'on')
>>> request = TestRequest()
>>> widget = CheckBoxWidget(field, request)
hasInput returns True when the request contains the field.<name>.used
value:
>>> 'field.foo.used' in request.form
False
>>> widget.hasInput()
False
>>> request.form['field.foo.used'] = ''
>>> widget.hasInput()
True
getInputValue returns True when field.<name> equals (and only equals) 'on':
>>> 'field.foo' in request.form
False
>>> widget.getInputValue()
False
>>> request.form['field.foo'] = 'true'
>>> widget.getInputValue()
False
>>> request.form['field.foo'] = 'on'
>>> widget.getInputValue()
True
Below is HTML output of rendered checkbox widgets. We will first define
a helper method condense the HTML output for display in this test:
>>> def normalize(s):
... return '\\n '.join(s.split())
Default widget rendering:
>>> print(normalize( widget() ))
<input
class="hiddenType"
id="field.foo.used"
name="field.foo.used"
type="hidden"
value=""
/>
<input
class="checkboxType"
checked="checked"
id="field.foo"
name="field.foo"
type="checkbox"
value="on"
/>
Hidden rendering:
>>> print(normalize( widget.hidden() ))
<input
class="hiddenType"
id="field.foo"
name="field.foo"
type="hidden"
value="on"
/>
Calling setRenderedValue will change what gets output:
>>> widget.setRenderedValue(False)
>>> print(normalize( widget() ))
<input
class="hiddenType"
id="field.foo.used"
name="field.foo.used"
type="hidden"
value=""
/>
<input
class="checkboxType"
id="field.foo"
name="field.foo"
type="checkbox"
value="on"
/>
The checkbox widget does not support None values, so a Bool required
constraint will always be met with checkbox input:
>>> field.required = True
>>> widget.getInputValue()
True
