Django 1.9-/ login /中的IOError
[英]Django 1.9 - IOError at /login/
問題描述
抱歉，如果我較早前問過這個問題，您是否想幫助我。 由於我認為問題寫得不好，不得不刪除該帖子。
所以我有一個登錄視圖，當我單擊“提交”時會引發錯誤：
Exception Type: IOError
Exception Value:
[Errno 22] Invalid argument: u"C:\\Users\\Me\\Desktop\\mysite\\templates\\{'user': <CustomUser: coco>}"
Traceback:
C:\Users\Me\Desktop\mysite\accounts\views.py in login
40. return render('all_posts.html', {'user': request.user}, context_instance=RequestContext(request))
最初，我的登錄視圖為：
返回HttpResponseRedirect（'/'）
而不是當前：
return render('all_posts.html', {'user': request.user}, context_instance=RequestContext(request))
和前一種方法一樣，因為它沒有引發任何錯誤，卻將我定向到正確的網址。 但是在我的模板中； {％如果request.user.is_authenticated％}無效。
所以我更改了它，希望讓我的模板顯示當前用戶的名字（Welcome，coco！） ，現在我得到了這個新錯誤。
這是我的views.py
def login(request):
"""
Log in view
"""
if request.method == 'POST':
form = AuthenticationForm(data=request.POST)
if form.is_valid():
user = authenticate(username=request.POST['username'], password=request.POST['password'])
if user is not None:
if user.is_active:
django_login(request, user)
return render('all_posts.html', {'user': request.user}, context_instance=RequestContext(request))
else:
form = AuthenticationForm()
return render_to_response('login.html', {
'authenticationform': form,
}, context_instance=RequestContext(request))
base.html
<div class="log_bar">
<ul>
{% if request.user.is_authenticated %}
<li>Welcome,</li>
<li><a href="{% url 'profile' %}">{{ user.username }}</a></li>
<li>|</li>
<li><a href="{% url 'logout' %}">Log Out</a></li>
{% else %}
<li>Please</li>
<li><a data-toggle="modal" data-target="#modal-login" href="">log in</a></li>
<li>or</li>
<li><a data-toggle="modal" data-target="#modal-register" href="">sign up</a></li>
{% endif %}
</ul>
</div><!-- /.log_bar -->
編輯1：登錄模板 login.html
{% load staticfiles %}
{% load crispy_forms_tags %}
<div class="modal" id="modal-login">
<div class="modal-dialog">
<div class="modal-content">
<form enctype="multipart/form-data" method="post" action="login/">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h3 class="modal-title">Log In</h3>
</div>
<div class="modal-body">
{% csrf_token %}
{{ authenticationform|crispy }}
</div>
<div class="modal-footer">
<input type='submit' class="btn btn-primary" value="Log In" />
</div>
</form>
</div>
</div>
</div>
編輯2：all_posts.html
all_posts現在為空。 基本上，它只是擴展了base.html。 我都會發布。
all_posts.html
{% extends "base.html" %}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
</body>
</html>
編輯3：urls.py
from django.conf.urls import url, include
from blog import views
from accounts.views import get_profile, login, logout, register
import accounts
urlpatterns = [
url(r'^textpost$', views.submit_textpost, name='textpost'),
url(r'^linkpost$', views.submit_linkpost, name='linkpost'),
url(r'^$', views.all_posts, name='all_posts'),
url(r'^all$', views.all_posts, name='all_posts'),
url(r'^new$', views.new_posts, name='new_posts'),
url(r'^all/top_hour$', views.top_posts_hour, name='top_hour'),
url(r'^all/top_day$', views.top_posts_day, name='top_day'),
url(r'^all/top_week$', views.top_posts_week, name='top_week'),
url(r'^all/top_month$', views.top_posts_month, name='top_month'),
url(r'^all/top_year$', views.top_posts_year, name='top_year'),
url(r'^all/top_beginning_of_time$', views.top_posts_all, name='top_beginning_of_time'),
url(r'u/(?P<username>[a-zA-Z0-9]+)$', accounts.views.get_profile, name='username'),
url(r'register$', register, name='register'),
url(r'^profile/(?P<username>\w+/$)', get_profile, name='profile'),
url(r'logout/$', logout, name='logout'),
url(r'^login/$', login, name='login'),
url(r'(?P<username>[a-zA-Z0-9]+)/$', views.get_sub, name='sub_url'),
url(r'(?P<username>[a-zA-Z0-9]+)/(?P<title_slug>[a-zA-Z0-9]+)/$', views.get_sub, views.title_slug, name='sub_post'),
url(r'^comments/', include('django_comments_xtd.urls')),
]
base.html完整
旁注*在我的nav class =“ navbar navbar-fixed-left navbar-static-top”中 ，請注意所有href都是空的，這是因為如果我嘗試填充{％url'new_posts'％}等。它將引發相同的回溯：
“功能”對象不可迭代 。 我不知道是否相關，但我想我應該提一下。 我現在什至不關心自己，我不想超越自己。 我現在正試圖學習如何進行正確的登錄。

render的第一個參數必須是request object ，第二個模板名稱和第三個上下文。
return render(request, 'all_posts.html', {'user': request.user})
