Question

I want to add custom buttons to the add/change form at the administration interface. By default, there are only three:

• Save and add another

• Save and continue editing

• Save

I have created some custom methods in my forms.py file, and I want to create buttons to call these methods. I have used the snippet http://djangosnippets.org/snippets/1842/, but it’s not exactly what I want. This one allows to create buttons and call methods from the admin.py file and not forms.py.

Is there a way to do that?

This is my admin.py code:

class CategoryAdmin(admin.ModelAdmin):
    prepopulated_fields = { "alias": ("title",) }
    form = CategoryForm

admin.site.register(Category, CategoryAdmin)

And my forms.py code:

class CategoryForm(forms.ModelForm):
    """
    My attributes
    """
    def custom_method(self):
        print("Hello, World!")

How do I create a button that calls "custom_method()"?

You can override admin/change_form.html. Copy the version in contrib.admin.templates into your project. Mine is myproject/templates/admin/change_form.html, but you could use /myproject/myapp/templates/admin/change_form.html.

Next, edit the copy and change the two references to the existing template tag, {% submit_row %}, to point to your own template tag, {% my_template_tag %}.

Base your template tag on the contrib.admin‘s {% submit_row %}, but edit the HTML template to contain any extra buttons you want to display.
