Question

我正在尝试将多选小部件添加到与char字段对应的管理视图中。

models.py

class Campaign(models.Model):
    name = models.CharField(max_length=128)
    start_date = models.DateTimeField(default=timezone.now)
    end_date = models.DateTimeField(blank=True, null=True)
    budget = models.IntegerField()
    target = models.IntegerField()
    component_choices = models.CharField(max_length=128, null=True, blank=True)

admin.py

class CampaignAdmin(admin.ModelAdmin):
    fieldsets = (
        ('Main', {
            'fields': ('name', ('start_date', 'end_date',),),
        }),
        ('Budget', {
            'fields': ('budget', 'target',),
        }),
        ('Payment', {
            'fields': ('payment_terms', 'payment_initial', 'payment_per_mvm'),
        }),
    )

    form = ComponentChoicesForm

admin.site.register(Campaign, CampaignAdmin)

forms.py

class ComponentChoicesForm(ModelForm):

    component_type_choices = tuple(
        (x.id, str(x))
        for x in ComponentType.objects.all()
    )

    class Meta:
        model = ComponentType
        fields = '__all__'

    available_components = forms.MultipleChoiceField(
        choices=component_type_choices)

但是，上述代码只显示fieldsets而不显示ComponentTypeChoices表单。我的目的是让用户从forms.py admin.py中生成的选项中进行选择，以便填充Campaign.component_choices字段。

您已为其他模型创建了表单，并在Campaign模型管理中使用了该表单。您应该为Campaign模型而不是ComponentType创建模型表单。

您的表单和模型管理员应该是这样的，

forms.py

class CampaignForm(ModelForm):

    class Meta:
        model = Campaign
        fields = '__all__'

    OPTIONS = (('a', 'A'),('b', 'B'),('c', 'C'))

    available_components = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple,
                                     choices=OPTIONS)

admin.py

class CampaignAdmin(admin.ModelAdmin):
    form = CampaignForm

Django Admin中的多选表单
