# Fields #
|
|
##########
|
|
|
|
Each Field class does some sort of validation. Each Field has a clean() method,
|
|
which either raises django.forms.ValidationError or returns the "clean"
|
|
data -- usually a Unicode object, but, in some rare cases, a list.
|
|
|
|
Each Field's __init__() takes at least these parameters:
|
|
required -- Boolean that specifies whether the field is required.
|
|
True by default.
|
|
widget -- A Widget class, or instance of a Widget class, that should be
|
|
used for this Field when displaying it. Each Field has a default
|
|
Widget that it'll use if you don't specify this. In most cases,
|
|
the default widget is TextInput.
|
|
label -- A verbose name for this field, for use in displaying this field in
|
|
a form. By default, Django will use a "pretty" version of the form
|
|
field name, if the Field is part of a Form.
|
|
initial -- A value to use in this Field's initial display. This value is
|
|
*not* used as a fallback if data isn't given.
|
|
|
|
Other than that, the Field subclasses have class-specific options for
|
|
__init__(). For example, CharField has a max_length option.
