如何在Django 2.1的网站页面“帖子列表”中显示管理员的“中等审核”帖子？

Question

Previous Ask

我想在管理员页面（工作人员）的网站页面“帖子列表”（模板“ post_list.html”）上显示一个新帖子，该帖子“适中”，例如“ scrin1”（帖子1-已发布；帖子2-“适度”）。普通用户只能在已发布的帖子中看到“帖子列表”，请参阅“ scrin2”。这是为了确保每个管理员都不会进入站点的管理面板，而是可以从站点页面“发布更新”（模板“ post_form.html”）（例如“ scrin3”）发布此帖子。 我试图用views.py（在PostListView中的form_valid）中的staff_member_required来做到这一点，但是没有成功。 如果帖子已被编辑，则在发布已编辑版本之前也必须进行审核。

以下代码显示了管理面板中帖子审核的实现。我只是不知道如何通过站点页面（而不是登录到管理面板，例如，从站点页面“ ... / post // update”）来对帖子（创建或更新）进行审核选中“审核”中的复选框）

models.py

class Post(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=50)
    body = models.TextField()
    moderation = models.BooleanField(default=False)

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('post-detail', kwargs={'pk': self.pk})

forms.py

from .models import Post

class PostForm(forms.ModelForm):
    title = forms.CharField(required=True)
    body = forms.CharField(widget=forms.Textarea)

    class Meta:
        model = Post
        fields = ['title', 'body']

views.py

from .forms import PostForm

class PostListView(generic.ListView):
    model = Post
    paginate_by = 10

    def get_queryset(self):
        queryset = super(PostListView, self).get_queryset()
        return queryset.filter(moderation=True)


class PostCreateView(FormView):
    form_class = PostForm
    template_name = 'blog/post_form.html'
    success_url = reverse_lazy('posts')

    def form_valid(self, form):
        response = super(PostCreateView, self).form_valid(form)
        form.instance.user = self.request.user
        form.save()
        return response


class PostUpdateView(PermissionRequiredMixin, UpdateView):
    model = Post
    fields = ['title', 'body']
    permission_required = 'blog.can_mark_returned'

admin.py

from .models import Post

class PostAdmin(admin.ModelAdmin):
    list_display = ('title', 'user', 'moderation')

admin.site.register(Post, PostAdmin)

urls.py

urlpatterns = [
    url(r'^posts/$', views.PostListView.as_view(), name='posts'),
    url(r'^post/(?P<pk>\d+)$', views.PostDetailView.as_view(), name='post-detail'),
    url(r'^post/create/$', views.PostCreateView.as_view(), name='post_create'),
    url(r'^post/(?P<pk>\d+)/update/$', views.PostUpdateView.as_view(), name='post_update'),
]

post_list.html

{% extends "base_generic.html" %}    
{% block title %}<title>Posts list</title>{% endblock %}
{% block content %}
    <h1>All posts</h1>
    {% if post_list %}
        <ul>
        {% for post in post_list %}
            <li><a href="{{ post.get_absolute_url }}">{{ post.title }}</a> {{ post.user }}</li>
        {% endfor %}
        </ul>
    {% else %}
    <p>There are no posts.</p>
    {% endif %}
{% endblock %}

post_form.html

{% extends "base_generic.html" %}
{% block content %}
    <form action="" method="post" enctype="multipart/form-data">
        {% csrf_token %}
        <table>
            {{ form.as_table }}
        </table>
        <input type="submit" value="Submit" />
    </form>
{% endblock %}

屏幕1 以“管理员”身份查看页面“帖子列表”

Screen2 以“常规用户”的身份查看页面“帖子列表”

Screen3 视图页面，将“发布更新”作为“管理员”并带有“审核”复选框

如果我真的了解您的问题，则可以如下更新视图。

{% extends "base_generic.html" %}    
{% block title %}<title>Posts list</title>{% endblock %}
{% block content %}
    <h1>All posts</h1>
    {% if post_list %}
        <ul>
        {% for post in post_list %}
            <li><a href="{{ post.get_absolute_url }}">{{ post.title }}</a> {{ post.user }}</li> 
            {% if post.moderation and request.user.is_staff %} 
                <form action="{% url 'moderator-approval' post.pk %}" method="post">
                {% csrf_token %}
                <button type="submit">Approve</button>
            {% endif %}
        {% endfor %}
        </ul>
    {% else %}
        <p>There are no posts.</p>
    {% endif %}
{% endblock %}

在您的urls.py

urlpatterns = [ 
     path('moderator-approval/<int:post_id>/', views.moderator_approval_view, name="moderator-approval")
]

在您的views.py

def moderator_approval_view(request, **kwargs):

    if request.method == 'POST':
        post = Post.objects.get(pk=kwargs['post_id'])
        post.moderation = True
        post.save()
        return HttpResponseRedirect('posts')
