Cleaning form data in Django
提问by Josh Hunt
How can i clean and modify data from a form in django. I would like to define it on a per field basis for each model, much like using ModelForms.
我如何清理和修改 django 表单中的数据。我想在每个模型的每个字段的基础上定义它，就像使用 ModelForms 一样。
What I want to achieve is automatically remove leading and trailing spaces from defined fields, or turn a title (from one field) into a slug (which would be another field).
我想要实现的是自动从定义的字段中删除前导和尾随空格，或者将标题（从一个字段）转换为 slug（这将是另一个字段）。

You can define clean_FIELD_NAME() methods which can validate and alter data, as documented here: http://docs.djangoproject.com/en/dev/ref/forms/validation/#ref-forms-validation
您可以定义可以验证和更改数据的 clean_FIELD_NAME() 方法，如下所述：http://docs.djangoproject.com/en/dev/ref/forms/validation/#ref-forms-validation
