python - 用户提交博客文章后重定向到主页？

Question

我对使用 Django 和一般编码非常陌生。所以我已经弄清楚如何使表单提交到我的数据库，但现在当它提交时，它只会将您带到空白的 blog_post View ，而我不明白如何正确重定向。

这是views.py:

from django.shortcuts import render, redirect
from .models import post
from django.views import generic, View
from django.views.decorators.http import require_GET
from django.http import HttpResponse, HttpResponseRedirect
from .forms import PostForm

# Views for post list


class postslist(generic.ListView):
    model = post
    queryset = post.objects.filter(status=1).order_by('-created_on')
    template_name = 'home.html'
    paginate_by = 4

# view for individual post


class postdetail(generic.DetailView):
    model = post
    template_name = "post.html"


def blog_post(request):

    form = PostForm(request.POST or None)

    if request.method == "POST":
        if form.is_valid():
            form.instance.user = request.user
            form.save()
        return redirect("blog:success")

    context = {'form': form,
               }

    return render(request, "create_post.html", context)


def success(request):
    return HttpResponseRedirect("home.html")

url.py:

from . import views
from django.urls import path, include
from .views import *


urlpatterns = [
    # home
    path('', views.postslist.as_view(), name='home'), 
    # add post
    path('blog_post/', views.blog_post, name='blog_post'),
    # success for blog post
    path('success/', views.success, name='success'),
    # posts
    path('<slug:slug>/', views.postdetail.as_view(), name='post_detail'),
]

我尝试了 httpresponseredirect 和重定向的一些变体，但我就是无法理解它，也无法在网上找到它。

假设您想在由 postslist View 呈现的 home.html 中进行重定向，因此 View 应如下所示:

def blog_post(request):

    if request.method == "POST":
       form=PostForm(request.POST)
        if form.is_valid():
            form.instance.user = request.user
            form.save()
            return redirect("blog:home")
    else:
        form = PostForm()

    context = {'form': form,
               }

    return render(request, "create_post.html", context)

还需要在urls.py中指定app_name='blog':

from . import views
from django.urls import path, include
from .views import *

app_name='blog'

urlpatterns = [
    # home
    path('', views.postslist.as_view(), name='home'), 
    # add post
    path('blog_post/', views.blog_post, name='blog_post'),
    # posts
    path('<slug:slug>/', views.postdetail.as_view(), name='post_detail')
]

删除不需要的成功 View 。
