Django表单问题:"WSGIRequest"对象没有属性"get" [英] Issue with Django-forms: 'WSGIRequest' object has no attribute 'get'

问题描述

我在Django调试视图中收到此错误:

 'WSGIRequest'对象没有属性'get' 

这是用于登录脚本的，大部分是从管理代码复制的，主要用于练习/调整原因.我在views.py中拥有的代码如下:

  @sensitive_post_parameters()@csrf_protect@never_cachedef login(request，template_name ="main/login.html"，authentication_form = LoginForm，redirect_field_name = REDIRECT_FIELD_NAME，current_app =无，extra_context =无):"显示登录表单并处理登录操作."redirect_to = request.REQUEST.get(redirect_field_name，'')如果request.method =="POST":形式= authentication_form(请求，数据=请求.POST)如果form.is_valid():#确保源自用户的重定向网址是安全的.如果不是is_safe_url(url = redirect_to，host = request.get_host()):redirect_to = resolve_url(settings.LOGIN_REDIRECT_URL)#好的，安全检查已完成.登录用户.用户= get_user(request.POST.get('email'))auth_login(请求，用户)返回HttpResponseRedirect(redirect_to)别的:形式= authentication_form(请求)current_site = get_current_site(请求)上下文= {表格":表格，redirect_field_name:redirect_to，'site':current_site，'site_name':current_site.name，}如果extra_context不为None:context.update(extra_context)return TemplateResponse(request，template_name，context，current_app = current_app) 

这是我的表格:

  Class LoginForm(forms.Form):电子邮件=形式.CharField(max_length = 100，标签=电子邮件"，小部件= forms.TextInput(attrs = {'class':'form-control'})，必填= True)密码= Forms.CharField(max_length = 32，label ="password"，widget = forms.PasswordInput(attrs = {'class':'form-control'})，必填= True) 

我在login.html的第13行收到我的错误

  {％扩展了'base_main.html'％}{％载入staticfiles％}{％block title％}登录{％endblock％}{％块样式表％}{{block.super}}< link rel ="stylesheet" type ="text/css" href ="{％static'main/css/login.css'％}">{％endblock％}{％格挡身体％}< div class ="container">{％，如果形式％}<！-< form class ="form-signin" role ="form" method ="POST" action ="/check_login/"> {％csrf_token％}->< h2 class ="form-signin-heading">请登录</h2>{{form}}<！-第13行-><！-< button class ="btn btn-lg btn-primary btn-block" type ="submit">登录</button></form>->{％ 万一 ％}</div>{％endblock％} 

有人知道如何解决这个问题吗?

解决方案

问题出在以下几行:

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

您的 LoginForm 类的init方法不会采用 django.contrib.auth.forms 中的 AuthenticationForm 那样的请求对象./p>

所以您可以这样做:

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

...但是实际上您当前的 LoginForm 类可能做得还不够，您应该查看Django(尤其是检查会话cookie等内容)，可能将其子类化.

I am getting this error in the Django debug-view:

'WSGIRequest' object has no attribute 'get'

This is for a login-script, which most of is copied from the admin-code, mostly for practice/tweaking-reasons. The code I have, in views.py, is following:

@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)

Here is my form:

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)

And I am receiving my error on line 13 in login.html

{% 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 %}

Anyone got any ideas to how I could solve this?

解决方案

The problem is in these lines:

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

Your LoginForm class' init method does not take a request object like the AuthenticationForm from django.contrib.auth.forms does.

So you could just do:

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

...but probably in fact your current LoginForm class does not do enough and you should look at the Django one (particularly the stuff around checking session cookie etc), possibly sub-class it.
