Django值太多，无法解压缩,django,python-3.x,Django,Python 3.x,我有一个错误：太多的值无法解包这似乎是我的清单有问题，或者可能是我填写清单的方式有问题 views.py favs = FavoriteGames.objects.filter(user_id=request.user.id).values_list('game_id', flat=True) mylist = [] for fav in favs: game = Games.objects.get(id=fav)

我有一个错误：太多的值无法解包这似乎是我的清单有问题，或者可能是我填写清单的方式有问题

views.py

        favs = FavoriteGames.objects.filter(user_id=request.user.id).values_list('game_id', flat=True)
        mylist = []
        for fav in favs:
            game = Games.objects.get(id=fav)
            mylist.append((game.id, game.guid, game.title, game.logo, "checked"), )
            nogame = Games.objects.filter(~Q(id__in=favs)).values_list('id', 'guid', 'title', 'logo')
        form = GamesEditorForm(games=mylist)

forms.py

class GamesEditorForm(forms.Form):
    def __init__(self, *args, **kwargs):
        self.games = kwargs.pop('games')
        super(GamesEditorForm, self).__init__(*args, **kwargs)
        self.fields['favorite_games'].choices = self.games  

favorite_games = forms.MultipleChoiceField(
    required=True,
    initial=True,
    widget=forms.CheckboxSelectMultiple(),
    )

模板

            {% for jeux in form.favorite_games %}
             <p>{{ jeux }}</p>
            {% endfor %}

问题是，在self.games中，您有一个包含项目的列表，其中每个项目包含5个元素，例如1、“paragon”、“paragon”、“paragon.png”、“checked”

中的每个选项都接受一对值。第一个是值本身，例如pk的1，第二个是人类可读的名称，例如标题的Paragon

在您的例子中，mylist变量传递的选项应该等于：[1，‘Paragon'，2，‘Paragon2'，]

看起来您还试图将它们标记为选中。如果您想为它们指定默认值，可以使用初始字段，您可以找到一些示例。

stacktrace请。我不知道怎么做，抱歉。复制粘贴并发布您在问题中收到的完整错误我用trackback更新了我的帖子，感谢您的帮助它说您在template/home/django project/agora/myaccount/templates/base.html中base.html的第16行有问题，第16行有错误
