Django的错误更改/还原浏览

Question

后，我正在改变较早涉及到一些地理位置（失败），并在恢复以前的看法的一些看法，我收到此错误：

TemplateSyntaxError at /report/all/ 
Caught NoReverseMatch while rendering: Reverse for 'profiles_profile_detail' with arguments '('',)' and keyword arguments '{}' not found. 

什么奇怪的是，我修改和恢复的视图与此视图或模板无关。 urls.py文件根本没有被触及。应用程序中的所有其他页面都正常显示。我无法弄清楚问题可能是什么。

查看：

from django.http import HttpResponse, HttpResponseRedirect, Http404 
from django.shortcuts import render_to_response, get_object_or_404, redirect 
from django.template import RequestContext 
from django.core.urlresolvers import reverse 
from myapp.report.models import Story, UserProfile 
from myapp.report.forms import ProfileForm, StoryForm 
from django.contrib.auth.decorators import login_required 
from django.contrib.gis.utils import GeoIP 

def all_stories(request): 
    if not request.user.is_authenticated(): 
     return redirect("django.contrib.auth.views.login") 
    all_stories = Story.objects.all().order_by("-date") 

    return render_to_response("report/storyline.html", 
           {'stories': all_stories}, 
           context_instance=RequestContext(request)) 

def story_detail(request, story_id): 
    story = get_object_or_404(Story, id=story_id) 
    return render_to_response('report/detail.html', 
          {'story': story}, 
           context_instance=RequestContext(request)) 

@login_required 
def submit_story(request): 
    if request.method =="POST": 
     story_form = StoryForm(request.POST, request.FILES) 
     if story_form.is_valid(): 
      new_story = story_form.save(commit=False) 
      new_story.author = request.user 
      new_story.save() 
      return HttpResponseRedirect("/report/all/") 
    else: # GET request 
     story_form = StoryForm() 
    return render_to_response("report/report.html", {'form': story_form}, context_instance=RequestContext(request)) 

形式（改变，但恢复;似乎运作）：

from django import forms 
from stentorian.report.models import UserProfile, Story 
from django.contrib.gis.utils import GeoIP 

class ProfileForm(forms.ModelForm): 
    class Meta: 
     model = UserProfile 

class StoryForm(forms.ModelForm): 
    class Meta: 
     model = Story 
     exclude = ('author',) 

模板：

{% extends 'base.html' %} 

{% block page_title %}Stentorian{% endblock %} 
{% block headline %}Stentorian Storyline{% endblock %} 

{% block content %} 

    <div class="row"> 
    <div class="span12"> 

     <h2>Welcome <a href="{% url profiles_profile_detail user.username %}">{{ user.username }}</a></h2> 

<div class="accordion" id="story_accordion"> 
     {% for story in stories %} 
      <div class="accordion-group"> 
       <div class="accordion-heading"> 
        <a class="accordion-toggle story-header" data-toggle="collapse" data-parent="#story_accordion" href="#story_{{ story.id }}"> 
         {{ story.title }} - {{ story.author.username }} - {{ story.date }} 
        </a> 
       </div> 
       <div id="story_{{ story.id }}" class="accordion-body collapse{% if forloop.counter0 == 0 %} in{% endif %}"> 
        <div class="accordion-inner"> 
         <!-- <h2><a href="{% url detail story.id %}">{{story.title}}</a></h2>--> 
         <span><a href="{% url profiles_profile_detail story.author %}">{{story.author}}</a> </span><br> 

         <span>{{story.topic}}</span><br> 
         <span>{{story.zip_code}}</span><br> 

         <span>{{story.date}}</span><br> 

         <p>{{story.copy}}</p> 
        </div> 
       </div> 
      </div> 

      <br> 

     {% endfor %} 
     </div> 

    </div> 
</div> 

{% endblock content %} 

错误就要到了就行了：

{% for story in stories %} 

如果有人能提供为什么会这样的想法，那将是十分赞赏。同样，url没有改变，这似乎是造成这个错误的主要原因。

Answer 1

似乎你没有得到user.username

试试这个吧。

<h2>Welcome <a href="{% url profiles_profile_detail request.user.username %}">{{ request.user.username }}</a></h2>
