create
根据给定值创建记录 (cr, user, vals, context=None) 参数:
* cr —— 数据库游标
* user —— 当前用户id
* vals —— 字段:值的字典
关系型字段的值用如下方式表示
* many2many 字段 : [(6, 0, list of ids)] (example: [(6, 0, [8, 5, 6, 4])])
* one2many 字段 : [(0, 0, dictionary of values)] (example: [(0, 0, {‘field_name’:field_value, ...})])
* many2one 字段 : 关联记录的ID
* reference 字段 : model name, id (例: ‘product.product, 5’)
many2many 字段 :
(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)
[size=24pt][color=red] (4, ID) link to existing record with id = ID (adds a relationship)[/color][/size]
(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)
one2many 字段:
(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)
* context —— 上下文，如语言、时区等
返回值: 新记录的id 异常： AccessError —— 如果用户没有创建这个对象的权限
ValidateError —— 如果用户在字段中输入的值不在该字段的selection参数的范围内
