这个问题首先要说什么?

这是我的model.py

class ProjectPage(Page):
"""
A Project Page

We access the People object with an inline panel that references the
ParentalKey's related_name in ProjectPeopleRelationship. More docs:
http://docs.wagtail.io/en/latest/topics/pages.html#inline-models
"""
introduction = models.TextField(
    help_text='Text to describe the page',
    blank=True)
image = models.ForeignKey(
    'wagtailimages.Image',
    null=True,
    blank=True,
    on_delete=models.SET_NULL,
    related_name='+',
    help_text='Landscape mode only; horizontal width between 1000px and 3000px.'
)
body = StreamField(
    BaseStreamBlock(), verbose_name="Page body", blank=True
)
subtitle = models.CharField(blank=True, max_length=255)
tags = ClusterTaggableManager(through=ProjectPageTag, blank=True)
date_published = models.DateField(
    "Date article published", blank=True, null=True
    )
#email = models.CharField(max_length=255, blank=True, null=True)
email = models.ForeignKey(User, on_delete=models.PROTECT, to_field='email', null=True)

content_panels = Page.content_panels + [
    FieldPanel('subtitle', classname="full"),
    FieldPanel('introduction', classname="full"),
    ImageChooserPanel('image'),
    StreamFieldPanel('body'),
    FieldPanel('date_published'),
    InlinePanel(
        'project_person_relationship', label="Author(s)",
        panels=None, min_num=1),
    FieldPanel('email'),
    FieldPanel('tags'),
    FieldPanel('added_by', classname="full"),
    FieldPanel('updated_by', classname="full"),
]

search_fields = Page.search_fields + [
    index.SearchField('body'),
]
added_by = models.ForeignKey(People,related_name="project_added_by", null=True, blank=True, on_delete=models.SET_NULL)
updated_by = models.ForeignKey(People,related_name="project_updated_by", null=True, blank=True, on_delete=models.SET_NULL)

created_at = models.DateTimeField(auto_now_add=True, null=True, blank=True)
updated_at = models.DateTimeField(auto_now=True, null=True, blank=True)

上述问题的解决方案是什么,如果您需要更多有关此问题的信息,请告诉我!!!!

我不知道,但我认为这里是电子邮件ID或其他地方的问题,因为在此之后可能会出现此问题,因此我添加了电子邮件ID。

1 个答案:

答案 0 :(得分:1)

在Django的email模型上User的声明是:

email = models.EmailField(_('email address'), blank=True)

This part of the Django documentation说,如果您链​​接到默认键之外的任何其他字段(例如您尝试链接到email的方式),则该字段必须用{{ 1}},但不是unique=True。尝试链接的问题是email模型的User字段上没有索引,因为它没有声明为唯一。

像这样链接到Django用户模型会更标准(默认情况下,链接是基于用户模型的默认键id)

email

使用上述声明,您将在模板中通过from django.contrib.auth import get_user_model user = models.ForeignKey(get_user_model(), on_delete=models.PROTECT, null=True) 收到链接用户的电子邮件,但是我不知道将用户链接到页面的体系结构。请记住,Wagtail具有权限结构,可用于为特定页面类型/模型的用户组分配权限。
