Question

Odoo模块始终包含两个文件__init__.py和__openerp__.py。

dhl_module
          |-- controller
          |-- models
          |-- views
          |-- __init__.py
          |-- __openerp__.py

文件__openerp__.py包含一个dict，但未将其指定给名称。该dict存储有关模块的信息。它看起来像这样：

# -*- coding: utf-8 -*-
{
    'name': "DHL connector",
    # used as subtitle
    'summary': "Configuration for DHL connector ",
    'description': """ DHL connector
    """,
    'author': "me",
    'website': "mysite.com",
    'category': 'Technical Settings',
    # Change the version every release for apps.
    'version': '0.0.1',
    # any module necessary for this one to work correctly
    'depends': [],
    # always loaded
    'data': ['views/dhl.xml', ],
    # only loaded in demonstration mode
    'demo': [],
    # only loaded in test
    'test': [],
    'installable': True,
    'application': True,
}

Odoo或我如何从__openerp__.py模块访问此dict？ dict变量未分配给名称。如何进口？

OpenERP不必导入该模块来获取该字典。他们只需将文件作为文本阅读，然后使用eval() 评估内容：

>>> text = '''\
... # -*- coding: utf-8 -*-
... {
...     'name': "DHL connector",
...     # used as subtitle
...     'summary': "Configuration for DHL connector ",
...     'description': """ DHL connector
...     """,
...     'author': "me",
...     'website': "mysite.com",
...     'category': 'Technical Settings',
...     # Change the version every release for apps.
...     'version': '0.0.1',
...     # any module necessary for this one to work correctly
...     'depends': [],
...     # always loaded
...     'data': ['views/dhl.xml', ],
...     # only loaded in demonstration mode
...     'demo': [],
...     # only loaded in test
...     'test': [],
...     'installable': True,
...     'application': True,
... }
... '''
>>> eval(text)
{'website': 'mysite.com', 'description': ' DHL connector\n    ', 'demo': [], 'depends': [], 'data': ['views/dhl.xml'], 'category': 'Technical Settings', 'name': 'DHL connector', 'author': 'me', 'summary': 'Configuration for DHL connector ', 'application': True, 'version': '0.0.1', 'test': [], 'installable': True}

那是exactly what OpenERP does：

MANIFEST = '__openerp__.py'

# ...

terp_file = mod_path and opj(mod_path, MANIFEST) or False

# ...

f = tools.file_open(terp_file)
try:
    info.update(eval(f.read()))
finally:
    f.close()

从模块导入没有名称的dict
