OpenERP/Odoo模型關係XML語法

Question

我正在使用OpenERP 7.0。 下面的代碼是來自文件addons/project/security/project_security.xml

請解釋我在哪裏數字4,6和0是從哪裏？ 在文檔中哪個地方可以諮詢一下？

<record id="group_project_user" model="res.groups"> 
    <field name="name">User</field> 
    <field name="category_id" ref="base.module_category_project_management"/> 
</record> 

<record id="group_project_manager" model="res.groups"> 
    <field name="name">Manager</field> 
    <field name="category_id" ref="base.module_category_project_management"/> 
    <field name="implied_ids" eval="[(4, ref('group_project_user'))]"/> 
    <field name="users" eval="[(4, ref('base.user_root'))]"/> 
</record> 

<record model="ir.ui.menu" id="base.menu_definitions"> 
    <field name="groups_id" eval="[(6,0,[ref('group_project_manager')])]"/> 
</record> 

Answer 1

對於many2many field，預計有一個元組列表。 這裏是被接受，與相應的語義元組的列表：

(0, 0, { values }) link to a new record that needs to be created with the given values dictionary 
(1, ID, { values }) update the linked record with id = ID (write *values* on it) 
(2, ID)    remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well) 
(3, ID)    cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself) 
(4, ID)    link to existing record with id = ID (adds a relationship) 
(5)     unlink all (like using (3,ID) for all linked records) 
(6, 0, [IDs])   replace the list of linked IDs (like using (5) then (4,ID) for each ID in the list of IDs) 

Example: 
[(6, 0, [8, 5, 6, 4])] sets the many2many to ids [8, 5, 6, 4] 

對於one2many場，元組列表的預期。 這裏是被接受，與相應的語義元組的列表：

(0, 0, { values }) link to a new record that needs to be created with the given values dictionary 
(1, ID, { values }) update the linked record with id = ID (write *values* on it) 
(2, ID)    remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well) 

Example: 
[(0, 0, {'field_name':field_value_record1, ...}), (0, 0, {'field_name':field_value_record2, ...})] 

我希望這會清除你的疑慮
