我正在使用选择的 jquery。我已经添加了null=Trueand和。但是为什么我在模板中收到验证错误？我尝试提交表单而不在管理员中填写 ManyToManyField 和 ForeignKey 并且它可以工作但不能在 tempalte 中。你会帮忙吗？谢谢blank=TrueManyToManyForeignKeyManyToManyField

多对多错误 -Enter a list of values.

模型

class Movie(models.Model):
    title = models.CharField(max_length=100)
    slug = models.SlugField(unique=True, max_length=100)
    director = models.ManyToManyField(Director, null=True, blank=True)
    writer = models.ManyToManyField(Writer, null=True, blank=True)
    producer = models.ManyToManyField(Producer, null=True, blank=True)
    starring = models.ManyToManyField(Starring, null=True, blank=True)
    screenplay = models.ManyToManyField(Screenplay, null=True, blank=True)

    editing = models.ForeignKey(Editing, null=True, blank=True)
    music = models.ForeignKey(Music, null=True, blank=True)
    studio = models.ForeignKey(Studio, null=True, blank=True)
    image = models.CharField(max_length=200, null=True, blank=True)

电影表格

class MovieForm(ModelForm):

  class Meta:
    model = Movie
    exclude = ('slug', 'image')
    widgets = {
        'director': Select(attrs={'multiple class': 'chzn-select'}),
        'starring': Select(attrs={'multiple class': 'chzn-select'}),
        'producer': Select(attrs={'class': 'chzn-select'}),
        'writer': Select(attrs={'class': 'chzn-select'}),
        'studio': Select(attrs={'class': 'chzn-select'}),
        'editing': Select(attrs={'class': 'chzn-select'}),
        'screenplay': Select(attrs={'class': 'chzn-select'}),
        'music': Select(attrs={'class': 'chzn-select'}),
    }

错误消息“输入值列表”意味着从表单返回的值不是列表或元组的实例，我认为问题是你使用Select小部件，它返回单个值（''如果为空），也许你应该使用SelectMultiple：

class MovieForm(ModelForm):
    class Meta:
        model = Movie
        exclude = ('slug', 'image')
        widgets = {
            'director': SelectMultiple(attrs={'class': 'chzn-select'}),
            ...
        }

或者您可以在表单清理之前手动将值转换为列表/元组。
