In the __opererp__.py you can use the special keys like:<\/p>\n
These keys can be very useful for doing lots of stuff like validating the module compatibility and it’s required dependency ,running some script at the time of installation .<\/p>\n
'external_dependencies': {\n 'python' : ['stripe'],\n },\n<\/pre>\nAt the time of installation if system does not have stripe library installed , it will raise an error and not allow to install the module.<\/p>\n<\/div>\n<\/div>\n
\n\npre init hook and <\/strong>POST INIT HOOK<\/strong><\/h3>\n<\/div>\n\nThe ‘pre_init_hook<\/strong>‘ is also a useful key available in __openerp __.py .<\/p>\nFor running the logic before registered the module in the ir.module.module<\/strong> you can use ‘pre_init_hook’.<\/p>\nFor Example :<\/em><\/p>\nAs many times we also have validate that the module build for Odoo8 should not be installed in Odoo9 in that case we use pre_init_hook .<\/p>\n
For using the pre_init_hook define this key in your __openerp__.py and assing it’s a method created in your __init_.py of module.
\nIn __opnerp__.py:<\/p>\n
'pre_init_hook':'pre_init_check',<\/pre>\nIn __init__.py:<\/p>\n
<\/p>\n
def pre_init_check(cr):\n\t# from openerp.service import common\n # from openerp.exceptions import Warning\n\t# version_info = common.exp_version()\n\t# server_serie =version_info.get('server_serie')\n\t# if server_serie!='8.0':raise Warning('Module support Odoo series 8.0 found {}'.format(server_serie))\n\treturn True\n\n\n<\/pre>\nWe can define the ‘post_init_hook<\/strong>‘ in the same ways:
\nIn __openerp__.py:<\/p>\n'post_init_hook': 'post_init_check',<\/pre>\nIn __init__.py:<\/p>\n
def post_init_check(cr, registry): \n # from openerp.service import common\n # from openerp.exceptions import Warning\n # version_info = common.exp_version()\n # server_serie =version_info.get('server_serie')\n # if server_serie!='8.0':raise Warning('Module support Odoo series 8.0 found {}'.format(server_serie))\n return True<\/pre>\n <\/p>\n<\/div>\n<\/div>\n
\n\nSAMPLE Code<\/strong><\/h3>\n<\/div>\n\nFinally __openerp__.py look like:<\/p>\n
....\n 'external_dependencies': {\n 'python' : ['stripe'],\n },\n 'pre_init_hook':'pre_init_check',\n 'post_init_hook': 'post_init_check', \n\n....<\/pre>\nAnd __init__.py look like:<\/p>\n
# -*- coding: utf-8 -*-\nimport models\nimport controllers\ndef post_init_check(cr, registry): \n # from openerp.service import common\n # from openerp.exceptions import Warning\n # version_info = common.exp_version()\n # server_serie =version_info.get('server_serie')\n # if server_serie!='8.0':raise Warning('Module support Odoo series 8.0 found {}'.format(server_serie))\n return True\ndef pre_init_check(cr):\n\tfrom openerp.service import common\n\tfrom openerp.exceptions import Warning\n\tversion_info = common.exp_version()\n\tserver_serie =version_info.get('server_serie')\n\tif server_serie!='8.0':raise Warning('Module support Odoo series 8.0 found {}'.format(server_serie))\n\treturn True\n\n\n<\/pre>\nFor further code reference you can visit this links over GitHub .<\/p>\n
