+# Widgets #
+###########
+
+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" />'
+
+# PasswordInput Widget ############################################################
+
+>>> w = PasswordInput()
+>>> w.render('email', '')
+u'<input type="password" name="email" />'
+>>> w.render('email', None)
+u'<input type="password" name="email" />'
+>>> w.render('email', 'test@example.com')
+u'<input type="password" name="email" value="test@example.com" />'
+>>> w.render('email', 'some "quoted" & ampersanded value')
+u'<input type="password" name="email" value="some &quot;quoted&quot; &amp; ampersanded value" />'
+>>> w.render('email', 'test@example.com', attrs={'class': 'fun'})
+u'<input type="password" name="email" value="test@example.com" class="fun" />'
+
+You can also pass 'attrs' to the constructor:
+>>> w = PasswordInput(attrs={'class': 'fun'})
+>>> w.render('email', '')
+u'<input type="password" class="fun" name="email" />'
+>>> w.render('email', 'foo@example.com')
+u'<input type="password" class="fun" value="foo@example.com" name="email" />'
+
+'attrs' passed to render() get precedence over those passed to the constructor:
+>>> w = PasswordInput(attrs={'class': 'pretty'})
+>>> w.render('email', '', attrs={'class': 'special'})
+u'<input type="password" class="special" name="email" />'
+
+>>> w.render('email', 'ŠĐĆŽćžšđ', attrs={'class': 'fun'})
+u'<input type="password" class="fun" value="\u0160\u0110\u0106\u017d\u0107\u017e\u0161\u0111" name="email" />'
+
+The render_value argument lets you specify whether the widget should render
+its value. You may want to do this for security reasons.
+>>> w = PasswordInput(render_value=True)
+>>> w.render('email', 'secret')
+u'<input type="password" name="email" value="secret" />'
+>>> w = PasswordInput(render_value=False)
+>>> w.render('email', '')
+u'<input type="password" name="email" />'
+>>> w.render('email', None)
+u'<input type="password" name="email" />'
+>>> w.render('email', 'secret')
+u'<input type="password" name="email" />'
+>>> w = PasswordInput(attrs={'class': 'fun'}, render_value=False)
+>>> w.render('email', 'secret')
+u'<input type="password" class="fun" name="email" />'
+
+# HiddenInput Widget ############################################################
+
+>>> w = HiddenInput()
+>>> w.render('email', '')
+u'<input type="hidden" name="email" />'
+>>> w.render('email', None)
+u'<input type="hidden" name="email" />'
+>>> w.render('email', 'test@example.com')
+u'<input type="hidden" name="email" value="test@example.com" />'
+>>> w.render('email', 'some "quoted" & ampersanded value')
+u'<input type="hidden" name="email" value="some &quot;quoted&quot; &amp; ampersanded value" />'
+>>> w.render('email', 'test@example.com', attrs={'class': 'fun'})
+u'<input type="hidden" name="email" value="test@example.com" class="fun" />'
+
+You can also pass 'attrs' to the constructor:
+>>> w = HiddenInput(attrs={'class': 'fun'})
+>>> w.render('email', '')
+u'<input type="hidden" class="fun" name="email" />'
+>>> w.render('email', 'foo@example.com')
+u'<input type="hidden" class="fun" value="foo@example.com" name="email" />'
+
+'attrs' passed to render() get precedence over those passed to the constructor:
+>>> w = HiddenInput(attrs={'class': 'pretty'})
+>>> w.render('email', '', attrs={'class': 'special'})
+u'<input type="hidden" class="special" name="email" />'
+
+>>> w.render('email', 'ŠĐĆŽćžšđ', attrs={'class': 'fun'})
+u'<input type="hidden" class="fun" value="\u0160\u0110\u0106\u017d\u0107\u017e\u0161\u0111" name="email" />'
+
+'attrs' passed to render() get precedence over those passed to the constructor:
+>>> w = HiddenInput(attrs={'class': 'pretty'})
+>>> w.render('email', '', attrs={'class': 'special'})
+u'<input type="hidden" class="special" name="email" />'
+
+# MultipleHiddenInput Widget ##################################################
+
+>>> w = MultipleHiddenInput()
+>>> w.render('email', [])
+u''
+>>> w.render('email', None)
+u''
+>>> w.render('email', ['test@example.com'])

+u'<input type="hidden" class="special" value="foo@example.com" 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')
+u'<input type="file" name="email" />'
+>>> 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" />'
+
+# 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', '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" />'
+
+# 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>
+
+>>> 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)

+
+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:
+...     print '<p>%s %s</p>' % (inp.tag(), inp.choice_label)
+<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>

+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)

+<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')))
