如何修复 Django url-routing, get_object_or_404and Slug 中的此类错误？

Question

如何准确获取URL中指定的系列，但是所有系列的名字都是一样的，应该是一样的，但是只需要URL系列本身，也就是说，它仅搜索 URL 系列，而不是搜索方式，因此该系列在 URL 中指定的系列中，并且在季节中也恰好是音量在URL这里指定的是url

Url 工作正常，但我无法转到正确的系列！

urlpatterns = [
   url(r'^$', homeview, name='homeview'),
   url(r'^subscribe/$', validate_email, name='subscribe'),   # /series/
   url(r'^(?P<serial_slug>[\w-]+)/$', post_of_serial, name='post_of_serial'),  # /series/Prison_Break/
   url(r'^(?P<serial_slug>[\w-]+)/(?P<season_slug>[\w-]+)/$', post_of_season, name='post_of_season'),  # /series/Prison_Break/season_5/
   url(r'^(?P<serial_slug>[\w-]+)/(?P<season_slug>[\w-]+)/(?P<series_slug>[\w-]+)/$', post_of_serie, name='post_of_serie'),  # /series/Prison_Break/season_5/2/  

]

        verbose_name_plural                     = 'Series'

views.py

def post_of_serie(request, serial_slug=None, season_slug=None, series_slug=None):
    serie                           = get_object_or_404(Series, serial_of_this_series=serial_slug, season_of_this_series=season_slug, slug=series_slug)
    #series_2                       = Series.objects.filter(serial_of_this_series=serial_slug, season_of_this_series=season_slug, slug=series_slug )
    context                         = {"serie":serie,}
    return render(request, 'series.html', context)

以上版本错误

ValueError at /series/Colony/Season_1/episode_1/

invalid literal for int() with base 10: 'Colony'

也有这样的选项，但是出现这样的错误，这样的名称已经存在。其实剧名和季名应该是一样的！

def post_of_serie(request, serial_slug=None, season_slug=None, series_slug=None):
    serie                           = get_object_or_404(Series, slug=series_slug)
    context                         = {"serie":serie,}
    return render(request, 'series.html', context)

Answer 1

尝试像这样编辑您的视图，

def post_of_serie(request, serial_slug=None, season_slug=None, series_slug=None):
    serie = get_object_or_404(Series, serial_of_this_series__slug=serial_slug, season_of_this_series__slug=season_slug, slug=series_slug)
    context = {"serie":serie,}
    return render(request, 'series.html', context)

serial_of_this_series是另一个table的ForeignKey，所以在访问该字段时，django会自动提供对应table的primary_key。通过查看您的错误，您似乎没有明确地将 slug 字段指定为 primary_key，然后 django 自动提供的自动递增整数字段正在尝试与 slug 匹配你刚刚提供。我建议访问 table 中的相应字段，例如 serial_of_this_series__slug，即 Serial table 中的 slug 字段（或任何字段名称） ] 用于查询过滤。
