Question

我在django-cms上写了一个自定义插件并添加了一个占位符字段。一旦在占位符上添加了该插件，我尝试在占位符字段中使用前端编辑插件添加它并抛出：

关于前端编辑

Failed to load resource: the server responded with a status of 404 (NOT FOUND)     
http://localhost:8000/es/admin/cms/page/add-plugin/

在控制台上显示

"POST /es/admin/cms/page/add-plugin/ HTTP/1.1" 404 1620

当我尝试使用管理界面或前端编辑

编辑放置在页面中的自定义插件时

TypeError at /es/admin/cms/page/4/edit-plugin/14/
<lambda>() takes exactly 1 argument (2 given)
Request Method: GET
Request URL:    http://localhost:8000/es/admin/cms/page/4/edit-plugin/14/
Django Version: 1.5.1
Exception Type: TypeError
Exception Value:    
<lambda>() takes exactly 1 argument (2 given)

Python Executable:  /home/ed/Envs/django/mh/../bin/python

我的插件代码如下所示

Models.py

from cms.models.pluginmodel import CMSPlugin
from cms.models.fields import PlaceholderField
from django.db import models

# Create your models here.
class Item(CMSPlugin):
title = models.CharField(max_length=100, default="Item Name",verbose_name=u'Titulo')
description = PlaceholderField('Item_Description')
image = models.ImageField(upload_to="uploads/images/",verbose_name=u'Imagen')
imageDescription = models.CharField(max_length=50,default="Image",verbose_name=u'Descripcion de la imagen')

admin.py

from django.contrib import admin
from cms.admin.placeholderadmin import PlaceholderAdmin
from projects.models import Item

admin.site.register(Item, PlaceholderAdmin)

cms_plugins.py

from cms.plugin_base import CMSPluginBase
from cms.plugin_pool import plugin_pool
from cms.models.pluginmodel import CMSPlugin
from django.utils.translation import ugettext_lazy as _

from models import Item

class ItemPlugin(CMSPluginBase):
    model = Item
    name = "Item Plugin"
    render_template = "item_plugin.html"
    def render(self, context, instance, placeholder):
        context['instance'] = instance
        return context

#Registers the plugin
plugin_pool.register_plugin(ItemPlugin)

VERSIONS

我正在使用

Django-cms: 2.2 
Django: 1.5.1
Linux: 12.04 LTS

请问我想知道如何在占位符字段内放置一个插件，然后输出那个恼人的错误。提前致谢

Answer 1

django CMS 2.2不支持Django 1.5 [1]。

如果您需要Django 1.5，请升级到最新的2.4版本。

Answer 2

ItemPlugin需要拥有PlaceholderAdmin的魔力。试试这个：

from cms.admin.placeholderadmin import PlaceholderAdmin
...
class ItemPlugin(CMSPluginBase, PlaceholderAdmin):
...

Django-cms占位符不起作用，抛出lambda异常
