Question

我与name中的Album Model匹配。它工作得很好。但是有些时候它并不匹配。它会引发错误消息Album matching query does not exist。如果找不到匹配，我想要。然后不要显示任何错误消息。可能吗？感谢

   def movie_details(request,slug):
    movies = get_object_or_404(Movie,slug=slug)
    # calculating wikipedia directory structer for images
    #image_name = movies.image
    name = movies.title
    album_name = Album.objects.get(name__exact=name)
    album_id = album_name.id
    song_list = Song.objects.filter(album=album_id)
    #image_path = generateWikiImage(image_name)
    #
    return render_to_response('base_movies.html',locals(),
                              context_instance=RequestContext(request)
                              )

错误消息

Album matching query does not exist

更新：

def movie_details(request,slug):
movies = get_object_or_404(Movie,slug=slug)
# calculating wikipedia directory structer for images
#image_name = movies.image
name = movies.title
try:
    album_name = Album.objects.get(name__exact=name)
    album_id = album_name.id
    song_list = Song.objects.filter(album=album_id)
except:
    pass

谢谢F.C.

Answer 1

正如上面的评论中所建议的那样，您需要捕获引发的异常。在你的情况下，它是：

try:
    album_name = Album.objects.get(name__exact=name)
except Album.DoesNotExist:
    pass

如果您想要将album_name设置为某个默认值，请将pass替换为代码，将其设置为默认值。
