I'm building the 'edit' page of my form. This page is supposed to show
form with the data that was saved, so the form is pre populated with saved
data. It works fine for most if the fields, but I have a problem with
'MultipleChoiceField' / 'CheckboxSelectMultiple' values that don't get
restored. So instead of having the corresponding checkboxes checked with
data from the saved form, they are all unchecked. This also affects
'SelectMultiple'
Could this be a bug ?
{{{
# forms.py
class MemberForm( forms.ModelForm ):
# ......
MODEL_CATEGORIES = (
('advisor', 'advisor'),
('member', 'member'),
('admin', 'admin'),
)
model_categories = forms.MultipleChoiceField(
widget = forms.CheckboxSelectMultiple,
choices = MODEL_CATEGORIES
)
class Meta:
model = Member
fields = [ 'model_categories' ]
# model
class Member( models.Model ):
model_categories = models.CharField(
max_length = 255,
null = True,
blank = True )
# Controller
def profile_edit_form( request ):
user = request.user or None
# Get user member profile instance
instance = get_object_or_404( Member, author = user )
form = MemberForm( request.POST or None, instance = instance )
context = {
"form" : form,
"instance": instance
}
if form.is_valid():
# ...
return redirect( 'profile_display' )
else:
# Initial form display, and redisplay of invalid form
return render( request, 'profile_edit_form_view.html', context )
# Template
<form action="/accounts/profile-edit-form/" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="Submit"/>
</form>
}}}
