How do you create two select menus with one dict where select menu B has values that correspond and are dependent to the keys present in select menu A?
In my Django views.py, I've created a dictionary that has a lists of Projects as keys, and corresponding Tasks as values within the dictionary. It looks like the following
Project A: Task 1
Project A: Task 2
Project A: Task 3
Project B: Task 1
Project B: Task 2
Project C: Task 1
I've been able to successfully pass this information into my Django template, but I can't wrap my head around how I can do what I need to do with the information.
I need to be able to take the information in the keys, ie the Projects, and create a drop down menu (A) which, when a key is selected, will display all of the corresponding tasks for the key in a second drop down menu (B)
I'm up to any kind of solution. I'm thinking about using jquery and hacking something together, but I'm really at a loss as to how to begin. Does anyone have experience with something like this?
You should likely also make a server verification in the form clean:
class MyForm(forms.Form): project = forms.ModelChoiceField(queryset=Project.objects.all()) task = forms.Model.ChoicField(queryset=Task.objects.all()) def clean(self): project = self.cleaned_data['project'] task = self.cleaned_data['task'] if task.project_id != project.pk: raise forms.ValidationError( "The selected task does not belong to the selected project.")
