解释OpenERP7.0中的安全性以及（6,0）和（4）的用途？

我见过这个

eval="[(6, 0, ref('test_security.base_security_access)])]" 

及

在OpenERP7.0代码中

6,0和4在安全性方面有什么用途？还有其他类似的组合吗？请解释。

（4，ID）

表示链接到ID=ID的现有记录，这将向现有记录添加关系

而

（6,0，[id]）

表示替换链接id的列表。首先，它将取消/删除现有ID与该记录的链接，然后使用ID列表中的每个ID链接到现有记录

对于删除现有ID和链接ID，它将删除两个对象之间的关系，但不会使用

（6,0，[id]）

关于更多细节，我最终在ORM write方法中找到了答案

• 对于多个字段，需要一个元组列表。 下面是接受的元组列表，以及相应的语义：

           (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)
  

           (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)
  

例如： [（6,0[8,5,6,4]）]将many2many设置为ids[8,5,6,4]

• 对于one2many字段，需要一小部分元组。 下面是接受的元组列表，以及相应的语义：

           (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)
  

           (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)
  

  例如： [（0,0，{'field\'name'：field\'value\'record1，…}），（0,0，{'field\'name'：field\'value\'record2，…}]

• 对于manyOne字段，只需使用目标记录的ID，该ID必须已经存在，或者

  False

  删除链接

• 对于引用字段，使用带有模型名称、逗号和目标对象id的字符串（例如：

  'product.product，5'

  ）

选项的完整列表在
（0，0，{values}）链接到需要使用创建的新记录 给定值字典
（1，ID，{values}）用ID=ID（write）更新链接记录 （上面的值）
（2，ID）删除ID=ID的链接记录（调用取消链接 在ID上，将完全删除该对象，并将其链接作为 嗯)
（3，ID）剪切到ID=ID的链接记录的链接（删除 两个对象之间的关系，但不删除目标 对象本身）
（4，ID）链接到ID=ID的现有记录（添加关系）
（5） 取消所有链接（如对所有链接记录使用（3，ID））
（6,0，[id]）替换链接id的列表（如使用（5）然后 （4，ID）用于ID列表中的每个ID）
