It seems I have to develop a custom django html widget
same concept on this page (look at the render method)
http://www.huyng.com/archives/django-custom-form-widget-for-dictionary-and-tuple-key-value-pairs/661/
so apparently I need a subclass of TextInput widget with a different
render method.
Note: I tried pretty much everything from the modelform such as
setting the 'initial' parameter in the forms.Charfield, but the
value is overwritten by the instance fields values.
26 class AssignmentEditForm(ModelForm):
50 def __init__(self, *args, **kwargs):
51 super(AssignmentEditForm, self).__init__(*args, **kwargs)
52
53 tagString = 'toto'
54 #if 'instance' in kwargs:
55 # assignment = kwargs['instance']
56 # tagString = ' '.join(tag.name for tag in
assignment.tag_set.all())
57 #self.fields['tag_set'].widget =
forms.TextInput(attrs={'size':70, })
58 self.fields['tag_set'].widget.attrs.update({
59 'size':70,
60 'class': "toto",
61 'value': "toto",
62 })
63 self.fields['tag_set'].initial='toto'
Nothing in the above works...
So custom textinput widget ....
