-
-Each Widget class corresponds to an HTML form widget. A Widget knows how to
-render itself, given a field name and some data. Widgets don't perform
-validation.

-# TextInput Widget ############################################################
-
->>> w = TextInput()
->>> w.render('email', '')
-u'<input type="text" name="email" />'
->>> w.render('email', None)
-u'<input type="text" name="email" />'
->>> w.render('email', 'test@example.com')
-u'<input type="text" name="email" value="test@example.com" />'
->>> w.render('email', 'some "quoted" & ampersanded value')
-u'<input type="text" name="email" value="some &quot;quoted&quot; &amp; ampersanded value" />'
->>> w.render('email', 'test@example.com', attrs={'class': 'fun'})
-u'<input type="text" name="email" value="test@example.com" class="fun" />'
-
-# Note that doctest in Python 2.4 (and maybe 2.5?) doesn't support non-ascii
-# characters in output, so we're displaying the repr() here.
->>> w.render('email', 'ŠĐĆŽćžšđ', attrs={'class': 'fun'})
-u'<input type="text" name="email" value="\u0160\u0110\u0106\u017d\u0107\u017e\u0161\u0111" class="fun" />'
-
-You can also pass 'attrs' to the constructor:
->>> w = TextInput(attrs={'class': 'fun'})
->>> w.render('email', '')
-u'<input type="text" class="fun" name="email" />'
->>> w.render('email', 'foo@example.com')
-u'<input type="text" class="fun" value="foo@example.com" name="email" />'
-
-'attrs' passed to render() get precedence over those passed to the constructor:
->>> w = TextInput(attrs={'class': 'pretty'})
->>> w.render('email', '', attrs={'class': 'special'})
-u'<input type="text" class="special" name="email" />'
-
-'attrs' can be safe-strings if needed
->>> w = TextInput(attrs={'onBlur': mark_safe("function('foo')")})
->>> print w.render('email', '')

->>> w.render('email', None)
-u'<input type="password" name="email" />'
->>> w.render('email', 'secret')
-u'<input type="password" name="email" />'
-
-The render_value argument lets you specify whether the widget should render
-its value. For security reasons, this is off by default.
-
->>> w = PasswordInput(render_value=True)
->>> w.render('email', '')
-u'<input type="password" name="email" />'

-
-# FileInput Widget ############################################################
-
-FileInput widgets don't ever show the value, because the old value is of no use
-if you are updating the form or if the provided file generated an error.
->>> w = FileInput()
->>> w.render('email', '')
-u'<input type="file" name="email" />'
->>> w.render('email', None)
-u'<input type="file" name="email" />'
->>> w.render('email', 'test@example.com')

->>> w.render('email', 'some "quoted" & ampersanded value')
-u'<input type="file" name="email" />'
->>> w.render('email', 'test@example.com', attrs={'class': 'fun'})
-u'<input type="file" name="email" class="fun" />'
-
-You can also pass 'attrs' to the constructor:
->>> w = FileInput(attrs={'class': 'fun'})
->>> w.render('email', '')
-u'<input type="file" class="fun" name="email" />'
->>> w.render('email', 'foo@example.com')
-u'<input type="file" class="fun" name="email" />'
-
->>> w.render('email', 'ŠĐĆŽćžšđ', attrs={'class': 'fun'})
-u'<input type="file" class="fun" name="email" />'
-
-Test for the behavior of _has_changed for FileInput. The value of data will
-more than likely come from request.FILES. The value of initial data will
-likely be a filename stored in the database. Since its value is of no use to
-a FileInput it is ignored.
-
->>> w = FileInput()
-
-# No file was uploaded and no initial data.
->>> w._has_changed(u'', None)
-False
-
-# A file was uploaded and no initial data.
->>> w._has_changed(u'', {'filename': 'resume.txt', 'content': 'My resume'})
-True
-
-# A file was not uploaded, but there is initial data
->>> w._has_changed(u'resume.txt', None)
-False
-
-# A file was uploaded and there is initial data (file identity is not dealt
-# with here)
->>> w._has_changed('resume.txt', {'filename': 'resume.txt', 'content': 'My resume'})
-True
-
-# Textarea Widget #############################################################
-
->>> w = Textarea()
->>> w.render('msg', '')
-u'<textarea rows="10" cols="40" name="msg"></textarea>'
->>> w.render('msg', None)
-u'<textarea rows="10" cols="40" name="msg"></textarea>'
->>> w.render('msg', 'value')
-u'<textarea rows="10" cols="40" name="msg">value</textarea>'
->>> w.render('msg', 'some "quoted" & ampersanded value')
-u'<textarea rows="10" cols="40" name="msg">some &quot;quoted&quot; &amp; ampersanded value</textarea>'
->>> w.render('msg', mark_safe('pre &quot;quoted&quot; value'))
-u'<textarea rows="10" cols="40" name="msg">pre &quot;quoted&quot; value</textarea>'
->>> w.render('msg', 'value', attrs={'class': 'pretty', 'rows': 20})
-u'<textarea class="pretty" rows="20" cols="40" name="msg">value</textarea>'
-
-You can also pass 'attrs' to the constructor:
->>> w = Textarea(attrs={'class': 'pretty'})
->>> w.render('msg', '')
-u'<textarea rows="10" cols="40" name="msg" class="pretty"></textarea>'
->>> w.render('msg', 'example')
-u'<textarea rows="10" cols="40" name="msg" class="pretty">example</textarea>'
-
-'attrs' passed to render() get precedence over those passed to the constructor:
->>> w = Textarea(attrs={'class': 'pretty'})
->>> w.render('msg', '', attrs={'class': 'special'})
-u'<textarea rows="10" cols="40" name="msg" class="special"></textarea>'
-
->>> w.render('msg', 'ŠĐĆŽćžšđ', attrs={'class': 'fun'})
-u'<textarea rows="10" cols="40" name="msg" class="fun">\u0160\u0110\u0106\u017d\u0107\u017e\u0161\u0111</textarea>'
-
-# CheckboxInput Widget ########################################################
-
->>> w = CheckboxInput()
->>> w.render('is_cool', '')
-u'<input type="checkbox" name="is_cool" />'
->>> w.render('is_cool', None)
-u'<input type="checkbox" name="is_cool" />'
->>> w.render('is_cool', False)
-u'<input type="checkbox" name="is_cool" />'
->>> w.render('is_cool', True)
-u'<input checked="checked" type="checkbox" name="is_cool" />'
-
-Using any value that's not in ('', None, False, True) will check the checkbox
-and set the 'value' attribute.
->>> w.render('is_cool', 'foo')
-u'<input checked="checked" type="checkbox" name="is_cool" value="foo" />'
-
->>> w.render('is_cool', False, attrs={'class': 'pretty'})
-u'<input type="checkbox" name="is_cool" class="pretty" />'
-
-You can also pass 'attrs' to the constructor:
->>> w = CheckboxInput(attrs={'class': 'pretty'})
->>> w.render('is_cool', '')
-u'<input type="checkbox" class="pretty" name="is_cool" />'
-
-'attrs' passed to render() get precedence over those passed to the constructor:
->>> w = CheckboxInput(attrs={'class': 'pretty'})
->>> w.render('is_cool', '', attrs={'class': 'special'})
-u'<input type="checkbox" class="special" name="is_cool" />'
-
-You can pass 'check_test' to the constructor. This is a callable that takes the
-value and returns True if the box should be checked.
->>> w = CheckboxInput(check_test=lambda value: value.startswith('hello'))
->>> w.render('greeting', '')
-u'<input type="checkbox" name="greeting" />'
->>> w.render('greeting', 'hello')
-u'<input checked="checked" type="checkbox" name="greeting" value="hello" />'
->>> w.render('greeting', 'hello there')
-u'<input checked="checked" type="checkbox" name="greeting" value="hello there" />'
->>> w.render('greeting', 'hello & goodbye')
-u'<input checked="checked" type="checkbox" name="greeting" value="hello &amp; goodbye" />'
-
-A subtlety: If the 'check_test' argument cannot handle a value and raises any
-exception during its __call__, then the exception will be swallowed and the box
-will not be checked. In this example, the 'check_test' assumes the value has a
-startswith() method, which fails for the values True, False and None.
->>> w.render('greeting', True)
-u'<input type="checkbox" name="greeting" />'
->>> w.render('greeting', False)
-u'<input type="checkbox" name="greeting" />'
->>> w.render('greeting', None)
-u'<input type="checkbox" name="greeting" />'
-
-The CheckboxInput widget will return False if the key is not found in the data
-dictionary (because HTML form submission doesn't send any result for unchecked
-checkboxes).
->>> w.value_from_datadict({}, {}, 'testing')
-False
-
->>> w._has_changed(None, None)
-False
->>> w._has_changed(None, u'')
-False
->>> w._has_changed(u'', None)
-False
->>> w._has_changed(u'', u'')
-False
->>> w._has_changed(False, u'on')
-True
->>> w._has_changed(True, u'on')
-False
->>> w._has_changed(True, u'')
-True
-
-# Select Widget ###############################################################
-
->>> w = Select()
->>> print w.render('beatle', 'J', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
-<select name="beatle">
-<option value="J" selected="selected">John</option>
-<option value="P">Paul</option>
-<option value="G">George</option>
-<option value="R">Ringo</option>
-</select>
-
-If the value is None, none of the options are selected:
->>> print w.render('beatle', None, choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
-<select name="beatle">
-<option value="J">John</option>
-<option value="P">Paul</option>
-<option value="G">George</option>
-<option value="R">Ringo</option>
-</select>
-
-If the value corresponds to a label (but not to an option value), none of the options are selected:
->>> print w.render('beatle', 'John', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
-<select name="beatle">
-<option value="J">John</option>
-<option value="P">Paul</option>
-<option value="G">George</option>
-<option value="R">Ringo</option>
-</select>
-
-The value is compared to its str():
->>> print w.render('num', 2, choices=[('1', '1'), ('2', '2'), ('3', '3')])
-<select name="num">
-<option value="1">1</option>
-<option value="2" selected="selected">2</option>
-<option value="3">3</option>
-</select>
->>> print w.render('num', '2', choices=[(1, 1), (2, 2), (3, 3)])
-<select name="num">
-<option value="1">1</option>
-<option value="2" selected="selected">2</option>
-<option value="3">3</option>
-</select>
->>> print w.render('num', 2, choices=[(1, 1), (2, 2), (3, 3)])
-<select name="num">
-<option value="1">1</option>
-<option value="2" selected="selected">2</option>
-<option value="3">3</option>
-</select>
-
-The 'choices' argument can be any iterable:
->>> from itertools import chain
->>> def get_choices():
-...     for i in range(5):
-...         yield (i, i)
->>> print w.render('num', 2, choices=get_choices())
-<select name="num">
-<option value="0">0</option>
-<option value="1">1</option>
-<option value="2" selected="selected">2</option>
-<option value="3">3</option>
-<option value="4">4</option>
-</select>
->>> things = ({'id': 1, 'name': 'And Boom'}, {'id': 2, 'name': 'One More Thing!'})
->>> class SomeForm(Form):
-...     somechoice = ChoiceField(choices=chain((('', '-'*9),), [(thing['id'], thing['name']) for thing in things]))
->>> f = SomeForm()
->>> f.as_table()
-u'<tr><th><label for="id_somechoice">Somechoice:</label></th><td><select name="somechoice" id="id_somechoice">\n<option value="" selected="selected">---------</option>\n<option value="1">And Boom</option>\n<option value="2">One More Thing!</option>\n</select></td></tr>'
->>> f.as_table()
-u'<tr><th><label for="id_somechoice">Somechoice:</label></th><td><select name="somechoice" id="id_somechoice">\n<option value="" selected="selected">---------</option>\n<option value="1">And Boom</option>\n<option value="2">One More Thing!</option>\n</select></td></tr>'
->>> f = SomeForm({'somechoice': 2})
->>> f.as_table()
-u'<tr><th><label for="id_somechoice">Somechoice:</label></th><td><select name="somechoice" id="id_somechoice">\n<option value="">---------</option>\n<option value="1">And Boom</option>\n<option value="2" selected="selected">One More Thing!</option>\n</select></td></tr>'
-
-You can also pass 'choices' to the constructor:
->>> w = Select(choices=[(1, 1), (2, 2), (3, 3)])
->>> print w.render('num', 2)
-<select name="num">
-<option value="1">1</option>
-<option value="2" selected="selected">2</option>
-<option value="3">3</option>
-</select>
-
-If 'choices' is passed to both the constructor and render(), then they'll both be in the output:
->>> print w.render('num', 2, choices=[(4, 4), (5, 5)])
-<select name="num">
-<option value="1">1</option>
-<option value="2" selected="selected">2</option>
-<option value="3">3</option>
-<option value="4">4</option>
-<option value="5">5</option>
-</select>
-
-# Choices are escaped correctly
->>> print w.render('escape', None, choices=(('bad', 'you & me'), ('good', mark_safe('you &gt; me'))))
-<select name="escape">
-<option value="1">1</option>
-<option value="2">2</option>
-<option value="3">3</option>
-<option value="bad">you &amp; me</option>
-<option value="good">you &gt; me</option>
-</select>
-
-# Unicode choices are correctly rendered as HTML
->>> w.render('email', 'ŠĐĆŽćžšđ', choices=[('ŠĐĆŽćžšđ', 'ŠĐabcĆŽćžšđ'), ('ćžšđ', 'abcćžšđ')])
-u'<select name="email">\n<option value="1">1</option>\n<option value="2">2</option>\n<option value="3">3</option>\n<option value="\u0160\u0110\u0106\u017d\u0107\u017e\u0161\u0111" selected="selected">\u0160\u0110abc\u0106\u017d\u0107\u017e\u0161\u0111</option>\n<option value="\u0107\u017e\u0161\u0111">abc\u0107\u017e\u0161\u0111</option>\n</select>'
-
-If choices is passed to the constructor and is a generator, it can be iterated
-over multiple times without getting consumed:
->>> w = Select(choices=get_choices())
->>> print w.render('num', 2)
-<select name="num">
-<option value="0">0</option>
-<option value="1">1</option>
-<option value="2" selected="selected">2</option>
-<option value="3">3</option>
-<option value="4">4</option>
-</select>
->>> print w.render('num', 3)
-<select name="num">
-<option value="0">0</option>
-<option value="1">1</option>
-<option value="2">2</option>
-<option value="3" selected="selected">3</option>
-<option value="4">4</option>
-</select>
-
-Choices can be nested one level in order to create HTML optgroups:
->>> w.choices=(('outer1', 'Outer 1'), ('Group "1"', (('inner1', 'Inner 1'), ('inner2', 'Inner 2'))))
->>> print w.render('nestchoice', None)
-<select name="nestchoice">
-<option value="outer1">Outer 1</option>
-<optgroup label="Group &quot;1&quot;">
-<option value="inner1">Inner 1</option>
-<option value="inner2">Inner 2</option>
-</optgroup>
-</select>
-
->>> print w.render('nestchoice', 'outer1')
-<select name="nestchoice">
-<option value="outer1" selected="selected">Outer 1</option>
-<optgroup label="Group &quot;1&quot;">
-<option value="inner1">Inner 1</option>
-<option value="inner2">Inner 2</option>
-</optgroup>
-</select>
-
->>> print w.render('nestchoice', 'inner1')
-<select name="nestchoice">
-<option value="outer1">Outer 1</option>
-<optgroup label="Group &quot;1&quot;">
-<option value="inner1" selected="selected">Inner 1</option>
-<option value="inner2">Inner 2</option>
-</optgroup>
-</select>

-RadioSelect uses a RadioFieldRenderer to render the individual radio inputs.
-You can manipulate that object directly to customize the way the RadioSelect
-is rendered.
->>> w = RadioSelect()
->>> r = w.get_renderer('beatle', 'J', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
->>> for inp in r:
-...     print inp
-<label><input checked="checked" type="radio" name="beatle" value="J" /> John</label>
-<label><input type="radio" name="beatle" value="P" /> Paul</label>
-<label><input type="radio" name="beatle" value="G" /> George</label>
-<label><input type="radio" name="beatle" value="R" /> Ringo</label>
->>> for inp in r:
-...     print '%s<br />' % inp
-<label><input checked="checked" type="radio" name="beatle" value="J" /> John</label><br />
-<label><input type="radio" name="beatle" value="P" /> Paul</label><br />
-<label><input type="radio" name="beatle" value="G" /> George</label><br />
-<label><input type="radio" name="beatle" value="R" /> Ringo</label><br />
->>> for inp in r:

-<p><input checked="checked" type="radio" name="beatle" value="J" /> John</p>
-<p><input type="radio" name="beatle" value="P" /> Paul</p>
-<p><input type="radio" name="beatle" value="G" /> George</p>
-<p><input type="radio" name="beatle" value="R" /> Ringo</p>
->>> for inp in r:
-...     print '%s %s %s %s %s' % (inp.name, inp.value, inp.choice_value, inp.choice_label, inp.is_checked())
-beatle J J John True
-beatle J P Paul False
-beatle J G George False
-beatle J R Ringo False
-
-You can create your own custom renderers for RadioSelect to use.
->>> class MyRenderer(RadioFieldRenderer):
-...    def render(self):
-...        return u'<br />\n'.join([unicode(choice) for choice in self])
->>> w = RadioSelect(renderer=MyRenderer)
->>> print w.render('beatle', 'G', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
-<label><input type="radio" name="beatle" value="J" /> John</label><br />
-<label><input type="radio" name="beatle" value="P" /> Paul</label><br />
-<label><input checked="checked" type="radio" name="beatle" value="G" /> George</label><br />
-<label><input type="radio" name="beatle" value="R" /> Ringo</label>
-
-Or you can use custom RadioSelect fields that use your custom renderer.
->>> class CustomRadioSelect(RadioSelect):
-...    renderer = MyRenderer
->>> w = CustomRadioSelect()
->>> print w.render('beatle', 'G', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
-<label><input type="radio" name="beatle" value="J" /> John</label><br />
-<label><input type="radio" name="beatle" value="P" /> Paul</label><br />
-<label><input checked="checked" type="radio" name="beatle" value="G" /> George</label><br />
-<label><input type="radio" name="beatle" value="R" /> Ringo</label>
-
-A RadioFieldRenderer object also allows index access to individual RadioInput
-objects.
->>> w = RadioSelect()
->>> r = w.get_renderer('beatle', 'J', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
->>> print r[1]
-<label><input type="radio" name="beatle" value="P" /> Paul</label>

->>> r[0].is_checked()

->>> r[1].is_checked()

-The value is compared to its str():

-<ul>

-<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>

-
-The 'choices' argument can be any iterable:
->>> def get_choices():
-...     for i in range(5):
-...         yield (i, i)
->>> print w.render('nums', [2], choices=get_choices())

-<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>
-<li><label><input type="checkbox" name="nums" value="4" /> 4</label></li>
-</ul>
-
-You can also pass 'choices' to the constructor:
->>> w = CheckboxSelectMultiple(choices=[(1, 1), (2, 2), (3, 3)])
->>> print w.render('nums', [2])
-<ul>
-<li><label><input type="checkbox" name="nums" value="1" /> 1</label></li>
-<li><label><input checked="checked" type="checkbox" name="nums" value="2" /> 2</label></li>
-<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>
-</ul>
-
-If 'choices' is passed to both the constructor and render(), then they'll both be in the output:
->>> print w.render('nums', [2], choices=[(4, 4), (5, 5)])
-<ul>
-<li><label><input type="checkbox" name="nums" value="1" /> 1</label></li>
-<li><label><input checked="checked" type="checkbox" name="nums" value="2" /> 2</label></li>
-<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>
-<li><label><input type="checkbox" name="nums" value="4" /> 4</label></li>
-<li><label><input type="checkbox" name="nums" value="5" /> 5</label></li>
-</ul>
-
-# Choices are escaped correctly
->>> print w.render('escape', None, choices=(('bad', 'you & me'), ('good', mark_safe('you &gt; me'))))
-<ul>
-<li><label><input type="checkbox" name="escape" value="1" /> 1</label></li>
