[docs]class ExternalBinding(models.AbstractModel): """ An abstract model for bindings to external records. An external binding is a binding between a backend and OpenERP. For example, for a partner, it could be ``magento.res.partner`` or for a product, ``magento.product``. The final model, will be an ``_inherits`` of the OpenERP model and will ``_inherit`` this model. It will have a relation to the record (via ``_inherits``) and to the concrete backend model (``magento.backend`` for instance). It will also contains all the data relative to the backend for the record. It needs to implements at least these fields: openerp_id The many2one to the record it links (used by ``_inherits``). backend_id The many2one to the backend (for instance ``magento.backend``). magento_id or prestashop_id or ... The ID on the backend. sync_date Last date of synchronization The definition of the relations in ``_columns`` is to be done in the concrete classes because the relations themselves do not exist in this addon. For example, for a ``res.partner.category`` from Magento, I would have (this is a consolidation of all the columns from the abstract models, in ``magentoerpconnect`` you would not find that):: class MagentoResPartnerCategory(models.Model): _name = 'magento.res.partner.category' _inherits = {'res.partner.category': 'openerp_id'} openerp_id = fields.Many2one(comodel_name='res.partner.category', string='Partner Category', required=True, ondelete='cascade') backend_id = fields.Many2one( comodel_name='magento.backend', string='Magento Backend', required=True, ondelete='restrict') magento_id = fields.Char(string='ID on Magento') tax_class_id = fields.Integer(string='Tax Class ID') _sql_constraints = [ ('magento_uniq', 'unique(backend_id, magento_id)', 'Partner Tag with same ID on Magento already exists.'), ] """ _name = 'external.binding' _description = 'External Binding (abstract)' sync_date = fields.Datetime(string='Last synchronization date')
