And*_*ewO 6 django django-allauth django-1.7 wagtail
在引入新应用程序(django-allauth)后执行迁移时出现错误.我不知道还有什么可以尝试以修复错误.我尝试了一些东西,但不幸的是它们似乎没有帮助.
运行manage.py migrate时:
File "D:\Python27\Lib\site-packages\django\db\migrations\state.py", line 71,
in render raise
InvalidBasesError("Cannot resolve bases for %r\nThis can happen if you are inheriting
models from an app with migrations (e.g. contrib.auth)\n in an app with no migrations;
see https://docs.djangoproject.com/en/1.7/topics/migrations/#dependencies for more" %
new_unrendered_models)
django.db.migrations.state.InvalidBasesError: Cannot resolve bases for
[<ModelState: 'blog.BlogPage'>, <ModelState: 'blog.BlogIndexPage'>]
This can happen if you are inheriting models from an app with migrations
(e.g. contrib.auth) in an app with no migrations; see
https://docs.djangoproject.com/en/1.7/topics/migrations/#dependencies for more
models.py
from django.db import models
from wagtail.wagtailcore.models import Page, Orderable
from wagtail.wagtailcore.fields import RichTextField
from wagtail.wagtailadmin.edit_handlers import FieldPanel ,MultiFieldPanel,InlinePanel, PageChooserPanel
from modelcluster.fields import ParentalKey
class BlogPage(Page):
body = RichTextField()
date = models.DateField("Post date")
indexed_fields = ('body', )
search_name = "Blog Page"
BlogPage.content_panels = [
FieldPanel('title', classname="full title"),
FieldPanel('date'),
FieldPanel('body', classname="full"),
]
class LinkFields(models.Model):
link_page = models.ForeignKey(
'wagtailcore.Page',
null=True,
blank=True,
related_name='+'
)
panels = [
PageChooserPanel('link_page'),
]
class Meta:
abstract = True
class RelatedLink(LinkFields):
title = models.CharField(max_length=255, help_text="Link title")
panels = [
FieldPanel('title'),
MultiFieldPanel(LinkFields.panels, "Link"),
]
class Meta:
abstract = True
class BlogIndexPageRelatedLink(Orderable, RelatedLink):
page = ParentalKey('blog.BlogIndexPage', related_name='related_links')
class BlogIndexPage(Page):
intro = models.CharField(max_length=256)
indexed_fields = ('body', )
search_name = "Blog Index Page"
BlogIndexPage.content_panels = [
FieldPanel('title', classname="full title"),
FieldPanel('intro', classname="full"),
InlinePanel(BlogIndexPage, 'related_links', label="Related links"),
]
到目前为止我尝试过的:
注意: makemigrations运行(未检测到更改)但迁移失败.
平台设置:目前在Windows机器上的Django 1.7.1上.django-allauth在此框中的其他应用程序中成功运行.
有没有人遇到过这个问题,有没有修复？
提前致谢

[这对我来说有什么问题] - 最终成为排序问题我猜...
现在似乎很开心.
希望这有助于某人并节省一些时间!

我也有错误Cannot resolve bases for ... This can happen if you are inheriting models from an app with migrations。原因python manage.py makemigrations是未创建任何迁移文件。这是因为我没有migrations文件夹。在我添加了该文件夹（__init__.py里面是一个空的）之后，一切正常。
