Split django.newforms into forms, fields, widgets, util. Also moved unit tests from docstrings to a standalone module in tests/regressiontests/forms, to save docstring memory overhead, keep code readable and fit our exisitng convention

# 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 "quoted" & ampersanded value" />'

|
||||
u'<input type="text" name="email" value="test@example.com" 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" />'

|
||||
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'})
|
||||

|

You can also pass 'attrs' to the constructor:

|

u'<textarea class="pretty" name="msg"></textarea>'
|
||||
>>> w.render('msg', 'example')
|
||||
u'<textarea class="pretty" name="msg">example</textarea>'
|
||||
|
||||
'attrs' passed to render() get precedence over those passed to the constructor:

Any Field can have a Widget class passed to its constructor:
|
||||
>>> class ContactForm(Form):
|
||||
... subject = CharField()
|
||||
... message = CharField(widget=Textarea)
|
||||
>>> f = ContactForm()
|
||||
>>> print f['subject']
|
||||
<input type="text" name="subject" />
|
||||
>>> print f['message']
|
||||
<textarea name="message"></textarea>
|
||||
|
||||
as_textarea() and as_text() are shortcuts for changing the output widget type:
|
||||
>>> f['subject'].as_textarea()
|
||||
u'<textarea name="subject"></textarea>'
|
||||
>>> f['message'].as_text()
|
||||
u'<input type="text" name="message" />'
|
||||
|
||||
The 'widget' parameter to a Field can also be an instance:
|
||||
>>> class ContactForm(Form):
|
||||
... subject = CharField()
|
||||
... message = CharField(widget=Textarea(attrs={'rows': 80, 'cols': 20}))
|
||||
>>> f = ContactForm()
|
||||
>>> print f['message']
|
||||
<textarea rows="80" cols="20" name="message"></textarea>
|
||||
|
||||
Instance-level attrs are *not* carried over to as_textarea() and as_text():
|
||||
>>> f['message'].as_text()
|
||||
u'<input type="text" name="message" />'
|
||||
>>> f = ContactForm({'subject': 'Hello', 'message': 'I love you.'})
|
||||
>>> f['subject'].as_textarea()
|
||||
u'<textarea name="subject">Hello</textarea>'
|
||||
>>> f['message'].as_text()
|
||||
u'<input type="text" name="message" value="I love you." />'
