How to populate drop down choice from data base in django form
I want to try populating fields from the database in Django form, but it's showing me blankly. Can anyone give me an idea? Here I am sharing my code.
class circleform(forms.ModelForm):
class Meta:
model = curd
fields = ['Zone','Circle','circle_code','circle_address']
widgets = {
'Zone':forms.Select(attrs = {'class':'form-control'}),
'Circle':forms.TextInput(attrs = {'class':'form-control'}),
'circle_code':forms.TextInput(attrs = {'class':'form-control'}),
'circle_address':forms.TextInput(attrs = {'class':'form-control'}),
}
I think you could use a field overriding like
class YourForm(forms.ModelForm):
your_foreign_key_field_name = forms.ModelChoiceField(queryset=YourChoiceModel.objects.all())
class Meta:
....
or in case you just want a form that reflect all your model's fields, try using Admin https://docs.djangoproject.com/en/4.1/intro/tutorial07/
If you are looking for a field that will populate your query based on a query then ModelChoiceField is what you are looking for. You can use it like that
class circleform(forms.ModelForm):
your_field = ModelChoiceField(queryset="you query here to populate choice field")
# ...
but if you have some hard-coded choices that you want to populate then you can pass a choices=YOUR_CHOICES_TUPLE
like that.
class circleform(forms.ModelForm):
class Meta:
model = curd
fields = ['Zone','Circle','circle_code','circle_address']
YOUR_CHOICES = (
('', 'Select your zone'),
('1', 'First'), #First one is the value of the select option and the second is the displayed value in the option
('2', 'second'),
)
widgets = {
'Zone':forms.Select(attrs = {'class':'form-control'}, choices=YOUR_CHOICES), # new
}
