You can achive this by creating custom modelchoice fields:
class CategoryModelChoiceField(ModelChoiceField):
def label_from_instance(self, obj):
return obj.category
class TimeModelChoiceField(ModelChoiceField):
def label_from_instance(self, obj):
return obj.time
class PreparationModelChoiceField(ModelChoiceField):
def label_from_instance(self, obj):
return obj.preparation
class ContentModelChoiceField(ModelChoiceField):
def label_from_instance(self, obj):
return obj.content
forms.py :
class FoodForm(forms.ModelForm):
category = CategoryModelChoiceField(queryset=Category.objects.all())
time = TimeModelChoiceField(queryset=Category.objects.all())
preparation = PreparationModelChoiceField(queryset=Category.objects.all())
content = ContentModelChoiceField(queryset=Category.objects.all())
class Meta:
model = FoodItems
fields = ('name','time', 'category', 'content', 'preparation', 'comment',)
