【问题描述】:
我在使用 wagtail 页面时遇到了一些问题。
从外壳
>>> Site.get_site_root_paths()
[(1, u'/home/', u'http://localhost')]
>>> BlogPage.objects.all()[0]
<BlogPage: Hello wagtail>
>>> BlogPage.objects.all()[0].url
>>> BlogPage.objects.all()[0].full_url
>>> BlogPage.objects.all()[0].status_string
'live'
>>> BlogPage.objects.all()[0].url_path
u'/blog/hello-wagtail/'
它工作了一段时间,我在 wagtail 管理员中将 Blog Page 从 root 移动到 Blog Index Page(请参阅下面的 models.py),由于某种原因,我移动的页面从管理员中消失了,所以我尝试通过使用./manage.py sycndb 和./manage.py migrate 再次创建我的数据库来重复我所做的步骤,再次创建页面,现在网址不再显示了。
我在wagtailcore/models.py 中添加了一个断点以查看发生了什么。关键部分似乎在这里:
@property
def url(self):
"""
Return the 'most appropriate' URL for referring to this page from the pages we serve,
within the Wagtail backend and actual website templates;
this is the local URL (starting with '/') if we're only running a single site
(i.e. we know that whatever the current page is being served from, this link will be on the
same domain), and the full URL (with domain) if not.
Return None if the page is not routable.
"""
root_paths = Site.get_site_root_paths()
for (id, root_path, root_url) in Site.get_site_root_paths():
if self.url_path.startswith(root_path):
return ('' if len(root_paths) == 1 else root_url) + self.url_path[len(root_path) - 1:]
self.url_path.startswith(root_path) 在我的情况下永远不会正确。
循环内的变量:
id = {int} 1
root_path = {unicode} u'/home/'
root_paths = {list} [(1, u'/home/', u'http://localhost')]
root_url = {unicode} u'http://localhost'
self = {Page} Blog
所有这些都意味着我创建的页面不可路由。我仍然可以使用 wagtail 管理员的预览模式正确查看我的页面,但我找不到为什么没有通往我的页面的路线:(。
这是我的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()
intro = RichTextField()
date = models.DateField("Post date")
indexed_fields = ('body', )
search_name = "Blog Page"
BlogPage.content_panels = [
FieldPanel('title', classname="full title"),
FieldPanel('date'),
FieldPanel('intro', classname="full"),
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('main.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"),
]
