Django錯誤：在視圖中的UnboundLocalError

Question

這一個真的讓我很難過。任何幫助，將不勝感激。

UnboundLocalError at /addauthor 
local variable 'form' referenced before assignment 
Request Method: POST 
Request URL: http://127.0.0.1:8000/addauthor 
Django Version: 1.4 
Exception Type: UnboundLocalError 
Exception Value:  
local variable 'form' referenced before assignment 
Exception Location: C:\Users\Nir\desktop\club\blog\views.py in addauthorView, line 8 
Python Executable: C:\Python27\python.exe 
Python Version: 2.7.6 

這裏是我的views.py：

from django.shortcuts import render 
from blog.forms import ContactForm 
from django.http import HttpResponseRedirect 

def addauthorView(request): 
    if request.method == 'POST': 
    f = ContactForm(request.POST) 
    if form.is_valid(): 
      first_name = form.cleaned_data['firstname'] 
      last_name = form.cleaned_data['lastname'] 
      user_email = form.cleaned_data['email'] 
      c = Contact(firstname=first_name, lastname=last_name, email=user_email) 
      c.save() 
      return HttpResponseRedirect('thanks/') 
    else: 
      form = ContactForm(request.POST) 
      return render(request, 'addauthor.html', {'form': ContactForm}) 
else: 
    return render(request, 'addauthor.html', {'form': ContactForm}) 


def thanksView(request): 
    return render(request, 'thanks.html') 

我可以根據要求張貼在我的Django項目其他的事情，但似乎這個問題是從意見快到了，我不知道爲什麼。

您正在使用form變量而未定義它。替換：

f = ContactForm(request.POST) 

有：

form = ContactForm(request.POST)
