In django, we canadmin.py Add ModelAdminIn this way, you can easily add, delete, modify, and query operations in the background. HoweverModel The generated forms are not friendly. we hope to make various types of controls like front-end development, so we have to customize the forms in the background.

In fact, django has provided us with some available form controls, such as multi-choice boxes and single-choice buttons. the following uses single-choice buttons as an example:

# Forms. pyfrom django import formsfrom. models import MyModelclass MyForm (forms. modelForm): xxx = forms. choiceField (choices = [...], widget = forms. radioSelect () class Meta: model = MyModel fields = ['id', 'XXX'] # admin. pyfrom django. contrib import adminfrom. models import MyModelfrom. forms import MyFormclass MyAdmin (admin. modelAdmin): form = MyForm #... the admin code is omitted. site. register (MyModel, MyAdmin)

First customizeMyForm, Add a control for the field,widget Used to specify the control type,choices Specify the optional list, and thenMyAdmin You can specify the form as a custom form.

Many widgets have been provided in django, but these are far from satisfying our needs. Therefore, we need to customize them, the following uses an ACE plug-in (ACE is an independent JavaScript-based Web code editor) as an example to describe how to customize widgets:
