Question

我最初使用kwargs填充我的djnago表单，

Forms.py

 class myForm(Forms.Form):  
   textbox1 = forms.CharField()  
   dropdown1 = forms.ChoiceField()  


   def __init__(self,*args,**kwargs):  
     choices = kwargs.pop('choices')  
     super(myForm,self).__init__(*args,**kwargs)  
     self.fields['dropdown1'] = forms.ChoiceField(choices=choices)

views.py

def myjob(req):  
  ch = {("1","A"),("2","B")}  
  if req.method == "POST":  
    frm = myForm(data=req.POST) # throws error saying can't find choices in Forms.py  
  else:  
    frm = myForm(choices=ch) # no problem here

此代码在提交数据时发出错误，因为它试图再次调用 init 。我该如何正确提交？

错误似乎很清楚：代码期待choices kwarg，而你没有在POST上提供它。你可以简单地添加它：

if req.method == "POST":  
    frm = myForm(data=req.POST, choices=ch)
