I have to add title attribute to options of the ModelChoiceField. Here is my admin code for that:
class LocModelForm(forms.ModelForm):
def __init__(self,*args,**kwargs):
super(LocModelForm,self).__init__(*args,**kwargs)
self.fields['icons'] = forms.ModelChoiceField(queryset = Photo.objects.filter(galleries__title_slug = "markers"))
self.fields['icons'].widget.attrs['class'] = 'mydds'
class Meta:
model = Loc
widgets = {
'icons' : forms.Select(attrs={'id':'mydds'}),
}
class Media:
css = {
"all":("/media/css/dd.css",)
}
js=(
'/media/js/dd.js',
)
class LocAdmin(admin.ModelAdmin):
form = LocModelForm
I can add any attribute to select widget, but i don't know how to add attributes to option tags. Any idea ?
First of all, don't modify fields in __init__
, if you want to override widgets use Meta
inner class, if you want to override form fields, declare them like in a normal (non-model) form.
If the Select
widget does not do what you want, then simply make your own. Original widget uses render_option
method to get HTML representation for a single option — make a subclass, override it, and add whatever you want.
class MySelect(forms.Select):
def render_option(self, selected_choices, option_value, option_label):
# look at the original for something to start with
return u'<option whatever>...</option>'
class LocModelForm(forms.ModelForm):
icons = forms.ModelChoiceField(
queryset = Photo.objects.filter(galleries__title_slug = "markers"),
widget = MySelect(attrs = {'id': 'mydds'})
)
class Meta:
# ...
# note that if you override the entire field, you don't have to override
# the widget here
class Media:
# ...
