Python Django通过manytomanyfield获取查询值

我是django的新手。
我以前练习过如何将数据保存到数据库中。
但现在我不知道如何查询我的数据。
请帮帮我，谢谢

这是我的模型：我在电影加热器上使用了很多文件

class Movie(models.Model):
    link = models.URLField()
    title = models.CharField(max_length=255, null=True)
    title_en = models.CharField(max_length=255, null=True)

class MovieTheater(models.Model):
    movietheater = models.ManyToManyField(Movie,null=True,blank=True,through="MovieShowtime")
    movie_theater = models.CharField(max_length=255, null=True)     

class MovieShowtime(models.Model):
    theater = models.ForeignKey( MovieTheater, null=True,blank=True,related_name = 'theater' )
    movie = models.ForeignKey( Movie, null=True,blank=True,related_name = 'movie' )
    time = models.TextField(null=True,blank=True)      

在my views.py中：

from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
from movie.models import Movie,MovieShowtime
from django.shortcuts import render 
def index(request):
    movies = Movie.objects.all()
    times = MovieShowtime.objects.all()
    contacts = get_paginator(request, movies, 10)
    return render(request, "movie/index.html",
                  {'contacts':contacts,'movies':movies,'times':times})

def get_paginator(request, object_list, num_per_page):
    paginator = Paginator(object_list, num_per_page)
    page = request.GET.get('page')
    try:
        ret = paginator.page(page)
    except PageNotAnInteger:
        ret = paginator.page(1)
    except EmptyPage:
        ret = paginator.page(paginator.num_pages)
    return ret  

我的电影/index.html：

<div class="activity">
    {% for movie in contacts %}
    <div class="col-md-12  item">
    <p><h3>{{ movie.title }}</h3></p>
           {{movie.id}}
        <div class="theater">
            {% for theater in movie.movietheater_set.all %}
                {{ theater.movie_theater }}
                {{ theater.id}}
                <!--I have to filter {{movie.id}} and  {{ theater.id}} to get the time like:
                MovieShowtime.objects.filter(movie_id='9',theater_id='5')So I can get the movietime.(I don't know if it is the normal way,It's what I can think now,please guide me)
                But I don't know how to do.
                -->
        {% endfor %}
        </div>
    </div>
{% endfor %}
</div>   

{contacts%%中的电影为%s}
{{movie.title}

{{movie.id}
{moviet.moviet\u set.all%中的剧场为%
{{剧院.电影院}
{{theater.id}
{%endfor%}
{%endfor%}

因为相关的名字，它很混乱。相关名称是oposite实体将访问其定义位置的名称

如果您这样做：

class MovieShowtime(models.Model):
    theater = models.ForeignKey(MovieTheater, null=True, related_name='showtimes' )
    movie = models.ForeignKey(Movie, null=True, related_name='showtimes' )

然后您将访问电影放映时间，如：

theater = MovieTheater.object.get(movie_theater='test')
for showtime in theater.showtimes.all:
  print "Movie: {} - Time: {}".format(showtime.movie.title, showtime.time)

你的例子是什么

get_paginator

-是一种基于类的视图方法。在

视图中显示所有导入。py

好的，我编辑它。这是我在Internet上找到的分页器。在你的

索引

视图中，你有

标题

未定义的变量。当你输入该视图的url时，你在浏览器中看到了什么？对不起，它是

标题='嘿'

它只是用于测试index.html是否获得了变量。已经没用了，我现在删除了。

theater = MovieTheater.object.get(movie_theater='test')
for showtime in theater.showtimes.all:
  print "Movie: {} - Time: {}".format(showtime.movie.title, showtime.time)
