我一直在尝试编写一个Django CMS插件,但是它没有出现在页面编辑的“可用插件”中,我很不确定为什么因为我已经阅读了另外几个插件的来源试图看看我是什么做错了.就像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)
models.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

)
解决方法:
问题是cms_plugins.py中的导入错误.你从linkrator.models导入LinksPlugin作为LinkListPluginModel,它应该来自linkrotator.models导入LinkListPluginModel.您还应该在LinkListPlugin上设置一个名称,或者当它显示在可用插件下时,该名称将为空.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并尝试从应用程序导入cms_plugins.py模块,从而导致问题.
