問題與Django的形式：「WSGIRequest」對象有沒有屬性「得到」

Question

我收到此錯誤Django的調試視圖：

'WSGIRequest' object has no attribute 'get' 

這是一個登錄腳本，其中大部分是從管理員代碼複製，主要是爲了練習/調整原因。我已經在views.py，是繼代碼：

@sensitive_post_parameters() 
@csrf_protect 
@never_cache 
def login(request, template_name="main/login.html", 
      authentication_form=LoginForm, 
      redirect_field_name=REDIRECT_FIELD_NAME, 
      current_app=None, extra_context=None): 
    """ 
    Displays the login form and handles the login action. 
    """ 
    redirect_to = request.REQUEST.get(redirect_field_name, '') 

    if request.method == "POST": 
     form = authentication_form(request, data=request.POST) 
     if form.is_valid(): 

      # Ensure the user-originating redirection url is safe. 
      if not is_safe_url(url=redirect_to, host=request.get_host()): 
       redirect_to = resolve_url(settings.LOGIN_REDIRECT_URL) 

      # Okay, security check complete. Log the user in. 
      user = get_user(request.POST.get('email')) 
      auth_login(request, user) 

      return HttpResponseRedirect(redirect_to) 
    else: 
     form = authentication_form(request) 
    current_site = get_current_site(request) 

    context = { 
     'form': form, 
     redirect_field_name: redirect_to, 
     'site': current_site, 
     'site_name': current_site.name, 
    } 
    if extra_context is not None: 
     context.update(extra_context) 
    return TemplateResponse(request, template_name, context, 
          current_app=current_app) 

這裏是我的形式：

class LoginForm(forms.Form): 
    email = forms.CharField(max_length=100, label="email", widget=forms.TextInput(attrs={'class': 'form-control'}), required=True) 
    password = forms.CharField(max_length=32, label="password", widget=forms.PasswordInput(attrs={'class': 'form-control'}), required=True) 

，我在接受login.html的第13行我的錯誤

{% extends 'base_main.html' %} 
{% load staticfiles %} 

{% block title %}Login{% endblock %} 
{% block stylesheet %} 
    {{ block.super }} 
    <link rel="stylesheet" type="text/css" href="{% static 'main/css/login.css' %}"> 
{% endblock %} 

{% block body %} 
    <div class="container"> 
     {% if form %} 
      <!-- 
      <form class="form-signin" role="form" method="POST" action="/check_login/">{% csrf_token %}--> 
       <h2 class="form-signin-heading">Please sign in</h2> 
       {{ form }} <!-- Line 13 --> 
       <!--<button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button> 
      </form> 
      --> 
     {% endif %} 
    </div> 
{% endblock %} 

任何人有任何想法，我怎麼能解決這個問題？

Answer 1

的問題是在這些行：

form = authentication_form(request, data=request.POST) 
... 
form = authentication_form(request) 

你LoginForm類init方法不從django.contrib.auth.forms確實需要像AuthenticationForm一個請求對象。

所以，你可能只是這樣做：

form = authentication_form(data=request.POST) 
... 
form = authentication_form() 

...但可能實際上當前的LoginForm類並沒有做足夠的，你應該看看Django的一個（特別是圍繞檢查會話cookie等東東） ，可能是分類的。
