6 表单 Forms

版权声明: 转载请注明出处 http://www.codingsoho.com/

There are three different things that you really don't want to get confused in Django:

• Model fields
• Form fields
• Form widgets

The model field controls what goes into the database, and when using the automatic form creation features, the model field type will give you a form containing a certain form field.

The form widgets control the HTML that the user interacts with in the form. For some form field types there might be more than one widget that could work (i.e. the time & date widgets admin uses versus the ones that are normally in user created forms).
