Integer Form with Select Widget?

[Farhan Khan]

Hi all,

I want to get an Integer value from the user through a forms.Form. I have three unique requirements for it.

1. The corresponding Widget is Select or SelectMultiple (either one)
   
2. The 'choices' field is dynamic, not static or hard-coded -they are adjusted upon each display of the Form based on program logic.
   
3. I want the max_value and min_value of IntegerField to also be dynamic - also adjusted based on program logic.
   

What I have thus far is this:

class deleteUserForm(forms.Form):

   delUserId = forms.CharField(label='delUserId', widget=forms.Select)

How would this work?

Thanks

Any takers? I suspect that I need to mess around with the form during instantiation, but not sure how.

Hi Farhan,

I can think of two ways. Either, like you said during form instantiation, do something like this:

class DeleteUserForm(forms.Form):
    def __init__(self, data=None, choices=None, more_info=None):
        super(DeleteUserForm, self).__init__(data)
        widget = forms.MultipleSelect if more_info else forms.Select
        self.fields['del_user_id'] = forms.CharField(label='User', widget=widget, choices=choices)
        self.fields['something_else'] = forms.IntegerField(min_value=something, max_value=something_else)

Or, in your view:

def myview(self):
    choices = something
    widget = something
    min_value = etc
    class DeleteUserForm(forms.Form):
        del_user_id = forms.CharField(label='User', widget=widget, choices=choices)
        something_else = forms.IntegerField(min_value=something, max_value=something_else)
    form = DeleteUserForm()
    if request.method ==  'POST':
        form = DeleteUserForm(request.POST)
    # etc
