Django形成编辑问题在intilization [英] Django form edit problem at intiliazation

问题描述

我在Django中预先填写表单时遇到麻烦。因为Aptana中的调试工具不能正常工作，我无法检测到错误。
我想当我尝试 form = MemberSettings（default_data）表单尝试验证数据，它给无效字段的错误，即使在第一次加载。

你能帮我找出问题吗？

谢谢

  class MemberSettings（forms.Form）：
 email = form.EmailField（label = _（member_Email），required = True）

} 
 form = MemberSettings default_data）
 return render_response（request，'use r / settings_edit.html'，{'form'：form}）
  

解决方案>

在视图中构建表单实例时，需要使用初始参数：

  form = MemberSettings（initial = default_data）
  

请参阅 https://docs.djangoproject.com/en/1.3/ref/forms/api/ 获取更多信息。希望能帮助你。

I have a trouble with pre-population of the forms in Django. Because debuggin tool in Aptana doesn't work well, I couldn't detect the error. I think when I try form = MemberSettings(default_data) form tries to validate the data and it gives errors for invalid fields even in first load.

Could you help me to find out the problem ?

Thanks

解决方案

You need to use the initial argument when constructing your form instance in the view:

form = MemberSettings(initial=default_data)

See https://docs.djangoproject.com/en/1.3/ref/forms/api/ for more information. Hope that helps you out.
