python - Django-CMS 插件未显示在可用插件中

Question

我一直在尝试编写一个 Django CMS 插件，但它没有出现在页面编辑的“可用插件”中，我非常不确定为什么我已经阅读了其他几个插件的源代码试图看看我做错了什么。就好像 Django-CMS 没有注册插件一样。

目录结构:

/linkrotator
  __init__.py
  admin.py
  cms_plugins.py
  links.html
  models.py
  tests.py
  views.py

cms_plugins.py

from cms.plugin_base import CMSPluginBase
from cms.plugin_pool import plugin_pool
from linkrator.models import LinksPlugin as LinksPluginModel

class LinkListPlugin(CMSPluginBase):
    text_enabled = True
    model = LinkListPluginModel
    render_template = "linkrotator/links.html"

    def render(self, context, instance, placeholder):
        context.update({'instance':instance})
        return context

plugin_pool.register_plugin(LinkListPlugin)

模型.py

from django.db import models
from cms.models import CMSPlugin

class LinkListPlugin(CMSPlugin):
    linklist = models.ForeignKey('linkrotator.LinkListList', related_name='plugins')

    def __unicode__( self ):
        return self.linklist.name

class Link(models.Model):
    name = models.CharField( max_length = 140 )
    in_list = models.ForeignKey( 'linkrotator.LinkList' )
    link = models.URLField()

    def __unicode__(self):
        return self.name

class LinkList(models.Model):
    name = models.CharField( max_length = 140 )
    in_list = models.ForeignKey('linkrotator.LinkListList', blank = True, null = True, on_delete=models.SET_NULL)

    def __unicode__(self):
        return self.name

class LinkListList(models.Model):
    name = models.CharField( max_length = 140 )
    number_of_links = models.IntegerField()

    def __unicode__(self):
        return self.name

问题是您的 cms_plugins.py 中的导入错误。您执行 from linkrator.models import LinksPlugin as LinkListPluginModel，它应该是 from linkrotator.models import LinkListPluginModel。您还应该在 LinkListPlugin 上设置一个名称，否则当它出现在可用插件下时，该名称将是空白的。给我们:

from linkrotator.models import LinkListPluginModel

class LinkListPlugin(CMSPluginBase):
    name = 'Link rotator'
    text_enabled = True
    model = LinkListPluginModel
    render_template = "linkrotator/links.html"

    def render(self, context, instance, placeholder):
        context.update({'instance':instance})
        return context

一般来说，如果您在加载插件时遇到问题，请打开 Django shell 并尝试从导致问题的应用中导入 cms_plugins.py 模块。
