如何在同一模板中傳遞另一個 model 的列表視圖和另一個 model 的詳細視圖

Question

我想使用基於 class 的視圖在同一模板中傳遞 model 后的列表視圖和電影 model 的詳細視圖

視圖.py

    from django.shortcuts import render, get_object_or_404
from django.contrib.auth.mixins import LoginRequiredMixin, UserPassesTestMixin
from django.urls import reverse
from django.views.generic import ListView, DetailView, CreateView, UpdateView, DeleteView, TemplateView
from .models import Post, Movies
from django.contrib.auth.models import User


class AboutView(TemplateView):
    template_name = 'blog/about.html'


class MoviesListView(ListView):
    model = Movies
    template_name = 'blog/home_movies.html'
    ordering = ['-date_released']
    context_object_name = 'movies'
    paginate_by = 10


class MoviesDetailListView(ListView):
    template_name = 'blog/post_list.html'
    context_object_name = 'posts'
    paginate_by = 10

    def get_queryset(self):
        user = get_object_or_404(Movies, name=self.kwargs.get('name'))
        return Post.objects.filter(name=user).order_by('-date_posted')

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        movie = get_object_or_404(Movies, pk=self.kwargs.get('pk'))
        context["movie"] = movie


class UserPostListView(ListView):
    model = Post
    template_name = 'blog/user_post.html'  # app/model_viewtype.html
    context_object_name = 'posts'
    ordering = ['-date_posted']
    paginate_by = 10

    def get_queryset(self):
        user = get_object_or_404(User, username=self.kwargs.get('username'))
        return Post.objects.filter(author=user).order_by('-date_posted')


class PostDetailView(DetailView):
    model = Post
    context_object_name = 'posts'


class PostCreateView(LoginRequiredMixin, CreateView):
    model = Post
    context_object_name = 'posts'
    fields = ['title', 'content', 'name']

    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)


class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
    model = Post
    template_name = 'blog/user_post_update.html'
    fields = ['title', 'content', 'name']

    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)

    def test_func(self):
        post = self.get_object()
        if self.request.user == post.author:
            return True
        return False

    def get_success_url(self, **kwargs):
        # obj = form.instance or self.object
        return reverse("movies-detail", kwargs={'name': self.object.name, 'id': self.object.id})


class PostDeleteView(LoginRequiredMixin, UserPassesTestMixin, DeleteView):
    model = Post

    def get_success_url(self, **kwargs):
        # obj = form.instance or self.object
        return reverse("movies-detail", kwargs={'name': self.object.name, 'id': self.object.id})

    def test_func(self):
        post = self.get_object()
        if self.request.user == post.author:
            return True
        return False

想要從通過 url 傳遞的電影 pk 打印 model 電影的詳細視圖

我從 url 傳遞了電影名稱和 pk 但無法獲得其他詳細信息，例如我們從 pk 獲得的 detailview

網址.py

urlpatterns = [

    path('about/', AboutView.as_view(), name='blog-about'),
    path('user/<str:username>/', UserPostListView.as_view(), name='user-post'),
    path('post/<int:pk>/', PostDetailView.as_view(), name='post-detail'),

    path('post/new/<str:name>/<int:id>/', PostCreateView.as_view(), name='post-create'),
    path('', MoviesListView.as_view(), name='blog-home'),
    path('<str:name>/<int:pk>/',MoviesDetailListView.as_view(), name='movies-detail'),
    path('post/<int:pk>/update/', PostUpdateView.as_view(), name='post-update'),
    path('post/<int:pk>/delete/', PostDeleteView.as_view(), name='post-delete'),

模型.py

from django.db import models
from django.contrib.contenttypes.fields import GenericForeignKey
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse
from PIL import Image


class Movies(models.Model):
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=100)
    producer = models.CharField(max_length=100)
    director = models.CharField(max_length=100)
    date_released = models.DateTimeField(default=timezone.now)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')

    class Meta:
        verbose_name_plural = "Movies"

    def __str__(self):
        return self.name


def get_id():
    return


class Post(models.Model):

    title = models.CharField(max_length=100)
    content = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    name = models.ForeignKey(Movies, on_delete=models.CASCADE,default=1)

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

    def get_absolute_url(self):
        return reverse('blog-home')

post_list.html

在這里我想了解電影的細節和帖子的細節

Answer 1

在上下文中添加 model 詳細信息，以便您可以在模板中使用它們，例如：

...
def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    movie = get_object_or_404(Movies, pk=self.kwargs.get('pk'))
    context["movie"] = movie
