自定义模块安装失败。表无法创建还是视图有错？
-
按照此例：<br / [检测到链接无效，已移除] br />编写的模块，在7.0安装时遇到错误：
File "/usr/lib/pymodules/python2.7/openerp/addons/base/ir/ir_ui_view.py", line 126, in _check_render_view
fvg = self.pool.get(view.model).fields_view_get(cr, uid, view_id=view.id, view_type=view.type, context=cont$
AttributeError: 'NoneType' object has no attribute 'fields_view_get'

验证字段 arch 时发生错误：Invalid XML for View Architecture!
Traceback (most recent call last):
File "/usr/lib/pymodules/python2.7/openerp/netsvc.py", line 292, in dispatch_rpc
result = ExportService.getService(service_name).dispatch(method, params)
File "/usr/lib/pymodules/python2.7/openerp/service/web_services.py", line 626, in dispatch
res = fn(db, uid, *params)

File "/usr/lib/pymodules/python2.7/openerp/osv/osv.py", line 144, in wrapper
raise except_osv(inst.name, inst.value)
错误的核心有两处，
一是
AttributeError: 'NoneType' object has no attribute 'fields_view_get'
此错误在launchpad上能找到相关的bug：<br / https://www.google.com.hk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&ved=0CEAQFjAC&url=https%3A%2F%2Fbugs.launchpad.net%2Fbugs%2F1077794&ei=Kmj3UY2eEsmXkwWuuoDIDg&usg=AFQjCNFzGWu7j6hd-wpbZMKINCIFL_2Bag br /> 明确说明此错误描述本身不清晰，应该是对象不存在导致xml结构验证错误，
二是
验证字段 arch 时发生错误：Invalid XML for View Architecture!
此位置一再验证无法看到错误，且有一的bug描述，应该不是根本原因。
数据库中确实没有我新增的oecn.training.lesson表存在。。。 -
搞两天居然还没搞定这个，信心受打击了呀～请大大帮忙则个：
