Django Forms，设置一个初始值为request.user [英] Django Forms, set an initial value to request.user

问题描述

 类JobRecordForm（forms.ModelForm ）
 supervisor = forms.ModelChoiceField（
 queryset = User.objects.filter（groups__name ='Supervisors'），
 widget = forms.RadioSelect，
 initial = request.user ＃有没有办法让这个可能？
）
 class Meta：
 model = JobRecord 
  

解决方案

您可能希望在您的视图功能中处理此问题。由于您的视图函数必须创建初始窗体，并且您的视图函数知道用户。

  form = JobRecordForm（{'supervisor' ：request.user}）
  

这将触发此输入的验证，BTW，所以你不能以这种方式提供提示值。

Is there some way to make the following possible, or should it be done elsewhere?

class JobRecordForm(forms.ModelForm):
    supervisor = forms.ModelChoiceField(
        queryset    = User.objects.filter(groups__name='Supervisors'), 
        widget      = forms.RadioSelect,
        initial     = request.user # is there some way to make this possible?
    )    
    class Meta:
        model = JobRecord

解决方案

You might want to handle this in your view function. Since your view function must create the initial form, and your view function knows the user.

form = JobRecordForm( {'supervisor':request.user} )

This will trigger validation of this input, BTW, so you can't provide hint values this way.
