<p>Validation is used to check that supplied values conform to a specification.</p>
<p>The value can be supplied as a string, e.g. from a config file. In this case
the check will also <em>convert</em> the value to the required type. This allows you
to add validation as a transparent layer to access data stored as strings. The
validation checks that the data is correct <em>and</em> converts it to the expected
type.</p>
<p>Checks are also strings, and are easy to write. One generic system can be used
to validate information from different sources via a single consistent
mechanism.</p>
<p>Checks look like function calls, and map to function calls. They can include
parameters and keyword arguments. These arguments are passed to the relevant
function by the <tt class="docutils literal"><span class="pre">Validator</span></tt> instance, along with the value being checked.</p>
<p>The syntax for checks also allows for specifying a default value. This default
value can be <tt class="docutils literal"><span class="pre">None</span></tt>, no matter what the type of the check. This can be used
to indicate that a value was missing, and so holds no useful value.</p>
<p>Functions either return a new value, or raise an exception. See <a class="reference internal" href="#validator-exceptions">Validator
Exceptions</a> for the low down on the exception classes that <tt class="docutils literal"><span class="pre">validate.py</span></tt>
defines.</p>
<p>Some standard functions are provided, for basic data types; these come built
into every validator. Additional checks are easy to write: they can be provided
when the <tt class="docutils literal"><span class="pre">Validator</span></tt> is instantiated, or added afterwards.</p>
<p>Validate was primarily written to support ConfigObj, but is designed to be
applicable to many other situations.</p>

<p>The standard functions come built-in to every <tt class="docutils literal"><span class="pre">Validator</span></tt> instance. They work
with the following basic data types :</p>
<ul class="simple">
<li>integer</li>
<li>float</li>
<li>boolean</li>
<li>string</li>
<li>ip_addr</li>
</ul>
<p>plus lists of these datatypes.</p>
<p>Adding additional checks is done through coding simple functions.</p>
<p>The full set of standard checks are :</p>

<p>The second method adds a set of your functions as soon as your validator is
created. They are stored in the <tt class="docutils literal"><span class="pre">vtor.functions</span></tt> dictionary. The &#8216;key&#8217; you
give them in this dictionary is the name you use in your checks (not the
original function name).</p>

want.</p>

<p>Some values may not be available, and you may want to be able to specify a
default as part of the check.</p>
<p>You do this by passing the keyword <tt class="docutils literal"><span class="pre">missing=True</span></tt> to the <tt class="docutils literal"><span class="pre">check</span></tt> method, as
well as a <tt class="docutils literal"><span class="pre">default=value</span></tt> in the check. (Constructing these checks is done

</div>
<p>If you pass in <tt class="docutils literal"><span class="pre">missing=True</span></tt> to the check method, then the actual value is
ignored. If no default is specified in the check, a <tt class="docutils literal"><span class="pre">ValidateMissingValue</span></tt>
exception is raised. If a default is specified then that is passed to the
check instead.</p>
<p>If the check has <tt class="docutils literal"><span class="pre">default=None</span></tt> (case sensitive) then <tt class="docutils literal"><span class="pre">vtor.check</span></tt> will
<em>always</em> return <tt class="docutils literal"><span class="pre">None</span></tt> (the object). This makes it easy to tell your program

optional, and may be omitted without harm.</p>

<p><tt class="docutils literal"><span class="pre">Validator</span></tt> instances have a <tt class="docutils literal"><span class="pre">get_default_value</span></tt> method. It takes a <tt class="docutils literal"><span class="pre">check</span></tt> string

<h3><a class="toc-backref" href="#id16">2.1.6. Writing check functions</a><a class="headerlink" href="#writing-check-functions" title="Permalink to this headline"></a></h3>
<p>Writing check functions is easy.</p>
<p>The check function will receive the value as its first argument, followed by
any other parameters and keyword arguments.</p>
<p>If the check fails, it should raise a <tt class="docutils literal"><span class="pre">VdtTypeError</span></tt> or a
<tt class="docutils literal"><span class="pre">VdtValueError</span></tt> (or an appropriate subclass).</p>
<p>All parameters and keyword arguments are <em>always</em> passed as strings. (Parsed
from the check string).</p>
<p>The value might be a string (or list of strings) and need
converting to the right type - alternatively it might already be a list of
integers. Our function needs to be able to handle either.</p>
<p>If the check passes then it should return the value (possibly converted to the
right type).</p>
<p>And that&#8217;s it !</p>
<div class="section" id="example">
<h4><a class="toc-backref" href="#id17">2.1.6.1. Example</a><a class="headerlink" href="#example" title="Permalink to this headline"></a></h4>
<p>Here is an example function that requires a list of integers. Each integer
must be between 0 and 99.</p>
<p>It takes a single argument specifying the length of the list. (Which allows us
to use the same check in more than one place). If the length can&#8217;t be converted
to an integer then we need to raise <tt class="docutils literal"><span class="pre">VdtParamError</span></tt>.</p>
<p>Next we check that the value is a list. Anything else should raise a
<tt class="docutils literal"><span class="pre">VdtTypeError</span></tt>. The list should also have &#8216;length&#8217; entries. If the list
has more or less entries then we will need to raise a
<tt class="docutils literal"><span class="pre">VdtValueTooShortError</span></tt> or a <tt class="docutils literal"><span class="pre">VdtValueTooLongError</span></tt>.</p>
<p>Then we need to check every entry in the list. Each entry should be an integer
between 0 and 99, or a string representation of an integer between 0 and 99.
Any other type is a <tt class="docutils literal"><span class="pre">VdtTypeError</span></tt>, any other value is a
<tt class="docutils literal"><span class="pre">VdtValueError</span></tt> (either too big, or too small).</p>

<p>If you are only using validate from ConfigObj then the error type (<em>TooBig</em>,
<em>TooSmall</em>, etc) is lost - so you may only want to raise <tt class="docutils literal"><span class="pre">VdtValueError</span></tt>.</p>
<div class="admonition caution">
<p class="first admonition-title">Caution</p>
<p>If your function raises an exception that isn&#8217;t a subclass of
<tt class="docutils literal"><span class="pre">ValidateError</span></tt>, then ConfigObj won&#8217;t trap it. This means validation will
fail.</p>
<p class="last">This is why our function starts by checking the type of the value. If we
are passed the wrong type (e.g. an integer rather than a list) we get a
<tt class="docutils literal"><span class="pre">VdtTypeError</span></tt> rather than bombing out when we try to iterate over
the value.</p>
</div>
<p>If you are using validate in another circumstance you may want to create your
own subclasses of <tt class="docutils literal"><span class="pre">ValidateError</span></tt> which convey more specific information.</p>

<p>The following parses and then blows up. The resulting error message
is confusing:</p>
<blockquote>
<div><tt class="docutils literal"><span class="pre">checkname(default=list(1,</span> <span class="pre">2,</span> <span class="pre">3,</span> <span class="pre">4)</span></tt></div></blockquote>
<p>This is because it parses as: <tt class="docutils literal"><span class="pre">checkname(default=&quot;list(1&quot;,</span> <span class="pre">2,</span> <span class="pre">3,</span> <span class="pre">4)</span></tt>.
That isn&#8217;t actually unreasonable, but the error message won&#8217;t help you
work out what has happened.</p>
