Question

我正在使用django-taggit（https://github.com/alex/django-taggit）。为了让用户添加标签，我使用一个表格字段，我将其转换为标签并添加它们。

但是，当我尝试加载模板进行编辑时。我在我的栏中获得了taggit对象。现在我想再次转换为普通可读字符串。但是，在将实例传递给我的表单之前，我似乎无法编辑该实例的字段。

表格：

class NewCampaignForm(forms.ModelForm):
""" Create a new campaign and add the searchtags """

    queryset = Game.objects.all().order_by("name")

    game = forms.ModelChoiceField(queryset=queryset, required=True)
    tags = forms.CharField(required=False)
    focus = forms.ChoiceField(required=False, choices=Campaign.CHOICES)

    class Meta:
        model = Campaign
        fields = ["game", "tags", "focus"]
        exclude = ["owner"]

我的模特：

class Campaign(models.Model):
    """ campaign information """

    ROLEPLAY = "Roleplay"
    COMBAT = "Combat"
    BOTH = "Both"
    CHOICES = (
        (ROLEPLAY, "Roleplay"),
        (COMBAT, "Combat"),
        (BOTH, "Both"),
    )

    owner = models.ForeignKey(User)

    game = models.ForeignKey(Game)
    focus = models.CharField(max_length=15, choices=CHOICES)
    tags = TaggableManager()

视图：

def campaign_view(request, campaign_id):
    campaign = get_object_or_404(Campaign, pk=campaign_id)
    campaign.tags = "Some string"
    new_campaign_form = NewCampaignForm(instance=campaign)

但是当我尝试这个时，我仍然在我的输入字段中获取taggit对象（[]）而不是“Some string” 我应该如何解决这个问题

Answer 1

我不确定我是如何忽视这一点的。但这有效：

new_campaign_form = NewCampaignForm(instance=campaign, initial={"tags": "Some String"})

对不起，应该看得更多并且尝试更好
