Comment (by sayane):
Here is a simple example. MultiLineAddressWidget is a subclass of
MultiWidget.
{{{
In [26]: w = MultiLineAddressWidget()
In [27]: w.render("myname", ["line1", "line2", "line3"])
Out[27]: u'<input type="text" name="myname_0" value="line1" /><br /><input
type="text" name="myname_1" value="line2" /><br /><input type="text"
name="myname_2" value="line3" />'
In [28]: w = forms.MultipleHiddenInput()
In [29]: w.render("myname", ["line1", "line2", "line3"])
Out[29]: u'<input type="hidden" name="myname" value="line1" />\n<input
type="hidden" name="myname" value="line2" />\n<input type="hidden"
name="myname" value="line3" />'
In [30]:
}}}
{{{
In [36]: data = {'myname': ['line1', 'line2', 'line3']}
In [37]: w = forms.MultipleHiddenInput()
In [38]: w.value_from_datadict(data, {}, "myname")
Out[38]: ['line1', 'line2', 'line3']
In [39]: w = MultiLineAddressWidget()
In [40]: w.value_from_datadict(data, {}, "myname")
Out[40]: [None, None, None]
}}}
I forgot to say that MultiValueField uses MultipleHiddenInput as default
hidden widget.
