I want to have additional fields regarding value of one field. Therefor I build a custom admin form to add some new fields.
Related to the blogpost of jacobian 1 this is what I came up with:
class ProductAdminForm(forms.ModelForm):
class Meta:
model = Product
def __init__(self, *args, **kwargs):
super(ProductAdminForm, self).__init__(*args, **kwargs)
self.fields['foo'] = forms.IntegerField(label="foo")
class ProductAdmin(admin.ModelAdmin):
form = ProductAdminForm
admin.site.register(Product, ProductAdmin)
But the additional field 'foo' does not show up in the admin. If I add the field like this, all works fine but is not as dynamic as required, to add the fields regarding the value of another field of the model
class ProductAdminForm(forms.ModelForm):
foo = forms.IntegerField(label="foo")
class Meta:
model = Product
class ProductAdmin(admin.ModelAdmin):
form = ProductAdminForm
admin.site.register(Product, ProductAdmin)
So is there any initialize method that i have to trigger again to make the new field working? Or is there any other attempt?
Here is a solution to the problem. Thanks to koniiiik i tried to solve this by extending the *get_fieldsets* method
class ProductAdmin(admin.ModelAdmin):
def get_fieldsets(self, request, obj=None):
fieldsets = super(ProductAdmin, self).get_fieldsets(request, obj)
fieldsets[0][1]['fields'] += ['foo']
return fieldsets
If you use multiple fieldsets be sure to add the to the right fieldset by using the appropriate index.
