Openerp 如何在odoo中创建关系字段？
关于如何在openerp中创建像one2many、many2many、ManyOne和One2OOne这样的关系字段，没有合适的示例。所以，谁能给我展示一下销售模块的例子。我没有销售模块的具体例子。但是，您可以从下面的语法中了解大致情况。它对任何类型的应用程序都有帮助。Openerp 如何在odoo中创建关系字段？,openerp,odoo,openerp-7,Openerp,Odoo,Openerp 7,关于如何在openerp中创建像one2many、many2many、ManyOne和One2OOne这样的关系字段，没有合适的示例。所以，谁能给我展示一下销售模块的例子。我没有销售模块的具体例子。但是，您可以从下面的语法中了解大致情况。它对任何类型的应用程序都有帮助。 class openerp.fields.Many2one(comodel_name=None, string=None, **kwargs) 基础：openerp.字段。\u 此类字段的值是大小为0（无记录）或1（单个记录）
class openerp.fields.Many2one(comodel_name=None, string=None, **kwargs)
comodel_name -- name of the target model (string)
domain -- an optional domain to set on candidate values on the client side (domain or string)
context -- an optional context to use on the client side when handling that field (dictionary)
ondelete -- what to do when the referred record is deleted; possible values are: 'set null', 'restrict', 'cascade'
auto_join -- whether JOINs are generated upon search through that field (boolean, by default False)
delegate -- set it to True to make fields of the target model accessible from the current model (corresponds to _inherits)
class openerp.fields.One2many(comodel_name=None, inverse_name=None, string=None, **kwargs)
class openerp.fields.Many2many(comodel_name=None, relation=None, column1=None, column2=None, string=None, **kwargs)
Parameters
comodel_name -- name of the target model (string)
inverse_name -- name of the inverse Many2one field in comodel_name (string)
domain -- an optional domain to set on candidate values on the client side (domain or string)
context -- an optional context to use on the client side when handling that field (dictionary)
auto_join -- whether JOINs are generated upon search through that field (boolean, by default False)
limit -- optional limit to use upon read (integer)
class openerp.fields.One2many(comodel_name=None, inverse_name=None, string=None, **kwargs)
class openerp.fields.Many2many(comodel_name=None, relation=None, column1=None, column2=None, string=None, **kwargs)
comodel_name -- name of the target model (string)
relation -- optional name of the table that stores the relation in the database (string)
column1 -- optional name of the column referring to "these" records in the table relation (string)
column2 -- optional name of the column referring to "those" records in the table relation (string)
The attributes relation, column1 and column2 are optional. If not given, names are automatically generated from model names, provided model_name and comodel_name are different!
