Django的CMS插件没有出现在可用的插件

Question

我一直在试图写一个Django CMS插件，但它没有显示在页面编辑“可用插件”起来，我非常不确定的原因我已经阅读了另外几个插件的源代码，试图查看我做错了什么。就好像Django-CMS没有注册插件。

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

Answer 1

的问题是在你的cms_plugins.py中导入错误。你from linkrator.models import LinksPlugin as LinkListPluginModel，它应该是from linkrotator.models import LinkListPluginModel。你也应该设置LinkListPlugin名称或名称将是空白时，它可以通过插件下显示出来。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，如果你有载入的插件问题，打开一个Django的外壳，并尝试从应用程序导致问题导入cms_plugins.py模块。

我想你的模板必须在文件夹中

linkrotator/templates/linkrotator/links.html 

您的结构将类似于

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

此外，我认为你的插件需要一个name属性http://django-cms.readthedocs.org/en/2.1.3/extending_cms/custom_plugins.html#cms-plugins-py
