相关疑难解决方法(0)

我有一个Django模型字段,我想内联.该领域是一种多对多的关系.所以有"项目"和"用户档案".每个用户配置文件可以选择任意数量的项目.

目前,我有"表格式"内联视图工作.有没有办法有一个"水平过滤器",以便我可以轻松地添加和删除用户配置文件中的项目？

请参阅附图以获取示例.

这是用户配置文件的型号代码:

class UserProfile(models.Model):
    user = models.OneToOneField(User, unique=True)
    projects = models.ManyToManyField(Project, blank=True, help_text="Select the projects that this user is currently working on.")

和项目的模型代码:

class Project(models.Model):
    name = models.CharField(max_length=100, unique=True)
    application_identifier = models.CharField(max_length=100)
    type = models.IntegerField(choices=ProjectType)
    account = models.ForeignKey(Account)
    principle_investigator = models.ForeignKey(User)
    active = models.BooleanField()

以及视图的管理代码:

class UserProfileInline(admin.TabularInline):
    model = UserProfile.projects.through
    extra = 0
    verbose_name = 'user'
    verbose_name_plural = 'users'

class ProjectAdmin(admin.ModelAdmin):
    list_display = ('name', 'application_identifier', 'type', 'account', 'active')
    search_fields = ('name', 'application_identifier', 'account__name')
    list_filter = ('type', 'active')
    inlines …

是否可以filter_horizontal用于ManyToManyField具有中间表的字段，例如没有中间表的字段？

例如：

class A(models.Model):
    f1 = models.ManyToManyField(B)
    f2 = models.ManyToManyField(C, through='T')

class B(models.Model):
    pass

class C(models.Model):
    pass

class T(models.Model):
    a = models.ForeignKey(A)
    c = models.ForeignKey(C)

class AAdmin(admin.ModelAdmin):
    filter_horizontal = ('f1', 'f2', )
