Django中的表单存在问题

Question

我试图实现一种让用户更改密码的表单。

下面的代码：

forms.py

class ChangePasswordForm(forms.Form): 
    password1 = forms.CharField(widget = forms.PasswordInput(), required = True) 
    password2 = forms.CharField(widget = forms.PasswordInput(), required = True) 

    def clean_password2(self): 
     password1 = self.cleaned_data.get("password1", "") 
     password2 = self.cleaned_data["password2"] 
     if password1 != password2: 
      raise forms.ValidationError("The two password fields didn't match.") 
     return password2 

    def save(self, *args, **kw): 
     self.user.set_password(self.cleaned_data['password1']) 
     print "Pass setted." 
     self.user.save() 

views.py

def change_password(request): 
    form = ChangePasswordForm() 
    if request.method == 'POST': 
     form = ChangePasswordForm(request.POST, instance = request.user) 
     if form.is_valid(): 
      password1 = form.cleaned_data['password1']; 
      password2 = form.cleaned_data['password2']; 
      print password1 + " == " + password2 
      form.save() 
      messages.success(request, "Password updated!") 
      return HttpResponseRedirect('') 

    return render(request, 'change_password.html', {'form': form}) 

，因为用户没有定义它不工作。问题是如何将用户传递给表单。想法？谢谢。

Answer 1

采取成全它的一个参数save方法。

def save(self, user): 
    user.set_password(self.cleaned_data['password1']) 
    user.save() 

... 


form.save(request.user)
