我对 django 比较陌生,我已经搜索过这个问题,但找不到解决方案。如果解决方案很明显,请原谅我,但我似乎无法正确解决。

所以,这就是问题所在。我有两个模型 Parishioner Community 。 Parishioner 与 Community 是多对一的关系。在 parishioner_detail 页面上,我试图将社区名称显示为 community_detail 页面的链接。我觉得我没有正确使用 get_absolute_url() 方法。任何帮助,将不胜感激。

楷模:

from django.db import models
from django.core.urlresolvers import reverse

class Community(models.Model):
    name = models.CharField(max_length=41)
    description = models.TextField()
    leader = models.CharField(max_length=41)
    email = models.EmailField()
    phone_number = models.CharField(max_length=20)
    slug = models.SlugField(max_length=31, unique=True)

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse('people_community_detail', kwargs={'slug': self.slug})

class Parishioner(models.Model):
    name = models.CharField(max_length=41)
    date_of_birth = models.DateField('date of birth', blank=True)
    email = models.EmailField()
    phone_number = models.CharField(max_length=20)
    start_date = models.DateField('date posted')
    societies = models.ManyToManyField(Society, blank=True, related_name='parishoners')
    communities = models.ForeignKey(Community, blank=True, related_name='parishoners')
    sacraments = models.ManyToManyField(Sacrament, blank=True, related_name='parishoners')
    slug = models.SlugField(max_length=31, unique=True)

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse('people_parishioner_detail', kwargs={'slug': self.slug})

    class meta:
        ordering = ['name']
        verbose_name_plural = "parishioners"

意见:
from django.shortcuts import get_object_or_404, render, redirect
from .models import Society, Community, Sacrament, Festival, Parishioner

def community_list(request):
    return render(request, 'people/community_list.html', {'community_list': Community.objects.all()})

def community_detail(request, slug):
    community = get_object_or_404(Community, slug__iexact=slug)
    return render(request, 'people/community_detail.html', {'community': community})

def parishioner_list(request):
    return render(request, 'people/parishioner_list.html', {'parishioner_list': Parishioner.objects.all()})

def parishioner_detail(request, slug):
    parishioner = get_object_or_404(Parishioner, slug__iexact=slug)
    return render(request, 'people/parishioner_detail.html', {'parishioner': parishioner})

parishioner_detail.html:
<dt>Community</dt>
  <dd><a href="{{ community.get_absolute_url }}">{{ parishioner.communities|title }}</a></dd>
<dt>Societies</dt>
  {% for society in parishioner.societies.all %}
    <dd><a href="{{ society.get_absolute_url }}">{{ society.name|title }}</a></dd>
  {% endfor %}

社会名称正确链接到 Society_detail 页面,但社区名称链接到 parishioner_detail 页面而不是 community_detail 页面。它基本上重新加载页面。

任何帮助,将不胜感激。
谢谢。

最佳答案

community 名称在您的上下文中不存在,因此 href 链接为空,您将重定向到同一页面。

你可能应该这样做:

 <dt>Community</dt>
 <dd><a href="{{ parishioner.communities.get_absolute_url }}">{{ parishioner.communities|title }}</a></dd>

最好将 communities 字段更改为单数(即 community ),因为它是一个外键字段,因此不那么容易混淆;一个教区居民对一个社区(不是多个社区)。
