Question

我对使用mysql的django orm有一些疑问。

这是我的models.py

from django.db import models

#电影列表
class Movieinfo(models.Model):
    movienum = models.IntegerField(primary_key=True)
    moviename = models.CharField(max_length=100)
    movierelease_time = models.CharField(max_length=20)
    movietype = models.CharField(max_length=100)

    class Meta:
        ordering = ["movienum"]
    def __str__(self):
        return self.moviename

#短评论
class Moviescritic(models.Model):
    movieinfo = models.ForeignKey(Movieinfo)
    movienum = models.IntegerField()
    moviescrit= models.TextField()

    class Meta:
        ordering = ["movienum"]
    def __str__(self):
        return self.moviescrit

#长影评
class Movielcritic(models.Model):
     movieinfo = models.ForeignKey(Movieinfo)
     movienum = models.IntegerField()
     movielcrittitle = models.TextField()
     movielcrit = models.TextField()

    class Meta:
        ordering = ["movienum"]
    def __str__(self):
        return self.movielcrit

这是我的views.py

import logging

from django.http import HttpResponse
from django.views.generic import DetailView
from django.template import loader

from yingping.models import Moviescritic

logger = logging.getLogger('__name__')

def cdview(request):
    template = loader.get_template('worldcloud.html')

    movie_shu = Moviescritic.objects.filter(
        movieinfo__movienum='10014'
    )
    content = {
        'movie_shu':movie_shu,
    }

   return HttpResponse(template.render(content,request))

但我在html中找不到任何数据，我对django onetomany的理解是错误的吗？

{% block worldcloud %}
    {% if movie_shu %}
        {% for x in movie_shu %}
            <p>{{x}}</p>
        {% endfor %}
    {% else %}
        print("err")
    {% endif %}
        <!--SERVICES SECTION END  -->
{% endblock %}

html只找到print("error")，当我在自己的表中找到数据时，我可以在HTML中找到数据。那我的代码有什么问题？

在django中找不到数据
