Django: a modelChoiceField depend on another modelChoiceField

i have two ModelChoiceFields that are populated with database :

t1=MyModelChoiceField1(queryset=operation_Bancaire.objects.all(),to_field_name='type_tiers',required=False)
t2=MyModelChoiceField2(queryset=operation_Bancaire.objects.all(),required=False)

i need to let the t2 depends on t1 . for example : if i choose value1 in t1 , t2 shows only values filtred by the value1 chooses in the first ModelChoiceField t1

i searched a lot about this and found some information that Ajax would help me to do so. but i'm not sure if it will let me control my ModelChoiceFields as i want specially that my ChoiceFields are populated from database, Because i have never worked with Ajax. Any Help please so i can be right oriented to achieve what i need.

Thank You.

  • You are right, ajax/javascript is the best way to do this. There is no inbuilt way in django to do this dynamically. This link is by far the most comprehensive in explaining how to implement ajax in django.
