Question

我有一个存储所有数据的模型。这是我的模型。py：

from django.db import models


class Showing(models.Model):
    movie_id = models.CharField(primary_key=True, max_length=11)
    movie_title = models.CharField(max_length=100)
    image_url = models.TextField(blank=True)
    synopsis = models.TextField(blank=True)
    rating = models.TextField(default="MTRCB rating not yet available")
    cast = models.CharField(max_length=100)
    release_date = models.CharField(max_length=50, blank=True)

    def __str__(self):
        return "{}".format(self.movie_id)

我想检索所有数据并将其传递给上下文，并像这样进行自定义JsonResponse：

    "results": [
        {
        "id": "1eb7758d-b950-4198-91b7-1b0ad0d81054",
        "movie": {
        "advisory_rating": "PG",
        "canonical_title": "ROGUE ONE: A STAR WARS STORY",
        "cast": [
        "Felicity Jones",
        "Donnie Yen",
        "Mads Mikkelsen"
        ],
        "poster_portrait": "",
        "release_date": "",
        "synopsis": "Set shortly before the events of Star Wars (1977), Following the foundation of the
        Galactic Empire, the story will center on a wayward band of Rebel fighters which comes together to carry out
        a desperate mission: to steal the plans for the Death Star before it can be used to enforce the Emperor's
        rule. (Source: Disney Pictures)",
        }
        },
       ]

在我的views.py中，我具有此功能来获取所有数据，并尝试仅从模型中检索movie_id。

def show_all_movies(request):
    movie = Showing.objects.all()
    context = {'result': [{
        'id': movie.movie_id,
        'movie':}]}

但是我得到了一个错误，“ QuerySet”对象没有属性“ movie_id”。所以我应该如何从数据库中检索数据，以便可以将其解析为json。谢谢。

当我尝试转储时。它返回如下：

"[{\"model\": \"movies.showing\", \"pk\": \"32b05a2f-e52f-55c6-8314-090bdd82e588\", \"fields\": {\"movie_title\": \"0f427f18-23d0-54e3-825e-b56a0f93786f\", \"image_url\": \"http://www.sureseats.com/images/events/movies/thumbnails/geostorm.gif\", \"synopsis\": \"When catastrophic climate change endangers Earth's very survival, world governments unite and create the Dutch Boy Program: a world wide net of satellites, surrounding the planet, that are armed with geoengineering technologies designed to stave off the natural disasters.

在您查看的电影对象中是一个查询集。您必须遍历它并处理任何对象。例如这样的

def show_all_movies(request):
    movies = Showing.objects.all()

    context={'result':[{
       'id':movie.movie_id,
       'movie': '...'} for movie in movies]}
