Question

我正在努力让用户可以编辑他们创建的文章。我觉得我很接近，但不能完全弥合我所做的和我需要做的事情的差距。

文章详细信息页面上的

模板：

{% if request.user == article.author %}
    <p>
      <a href="{% url 'articles:edit_article' %}"
        Edit article
      </a>
    </p>
    {% endif %}

这似乎工作正常。

urls.py：

url(r'^(?P<slug>[\w-]+)/$', views.article_detail, name="detail"),
url(r'^(?P<slug>[\w-]+)/edit/$', views.edit_article, name="edit_article"),

views.py：

def edit_article(request):
if request.method == 'POST':
    form = forms.EditArticle(request.POST, slug=request.slug)
    if form.is_valid():
        form.save()
        return redirect('articles:list')
else:
    form = forms.EditArticle(slug=request.slug)
    args = {'form': form}
    return render(request, 'articles/edit_article.html', args)

forms.py

class EditArticle(forms.ModelForm):
class Meta:
    model = models.Article
    fields = (
        'title',
        'body',
        'slug',
        'thumb'
    )

并且edit_article.html：

{% extends 'base_layout.html' %}

{% block content %}
<h1>Edit Article {{ article.title }}</h1>
<div class="profile">
  <form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Update Profile</button>
  </form>
</div>
{% endblock %}

这是追溯：

Exception Type: NoReverseMatch at /articles/testing-1212/
Exception Value: Reverse for 'edit_article' with no arguments not found. 1 pattern(s) tried: [u'articles/(?P<slug>[\\w-]+)/edit/$']

我猜这个问题是在slug的视图中。我试图以我的工作视图为基础来编辑用户配置文件，所以我猜我在翻译中丢失了一些东西。我觉得这只是工作中的一两个调整。有什么想法吗？

你应该：

{% if request.user == article.author %}
 <p>
  <a href="{% url 'articles:edit_article' article.slug %}"
    Edit article
  </a>
</p>
{% endif %}

您的观点

def edit_article(request,slug):
    article = Article.objects.get(slug=slug) # Better to use get_object_or_404 from django.http
    if request.method == 'POST':
        form = forms.EditArticle(request.POST, instance=article)
         if form.is_valid():
              form.save()
              return redirect('articles:list')
    else:
         form = forms.EditArticle(instance=article)
    args = {'form': form}
    return render(request, 'articles/edit_article.html', args)
