Onchange 里面传入的 one2many 的解读

[ccdos]

onchange 里面 就是把 传入的参数 print 出来

<br />&nbsp; &nbsp; def onchange_sale_order_contract_lines(self, cr, uid, ids,sale_order_contract_lines, context=None ):<br />&nbsp; &nbsp; &nbsp; #&nbsp; res = {&#039;value&#039;:{}}<br />&nbsp; &nbsp; &nbsp; #&nbsp; return res<br /><br />&nbsp; &nbsp; &nbsp; &nbsp; if sale_order_contract_lines:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for contract_line in sale_order_contract_lines:<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; print contract_line<br />&nbsp; &nbsp; &nbsp; &nbsp; return res<br />

运行若干次，结果如下：


下面 1，2 两行是 之前已经输入，修改了

3，4，5 行是新输入的，尚未保存

[1, 1, {u&#039;notes&#039;: u&#039;bbbb &#039;, u&#039;metric_spec&#039;: u&#039;aaaaaaaaaaaa&#039;}]<br />[1, 2, {u&#039;notes&#039;: u&#039; &#039;, u&#039;metric_spec&#039;: u&#039;bbbbbbbbbbbbbb&#039;}]<br />[0, False, {u&#039;input_value&#039;: 0, u&#039;input_type&#039;: u&#039;1&#039;, u&#039;notes&#039;: u&#039;ccc&#039;, u&#039;stratify_base&#039;: 100, u&#039;active&#039;: 1, u&#039;metric_spec&#039;: u&#039;ccccc&#039;}]<br />[0, False, {u&#039;input_value&#039;: 0, u&#039;input_type&#039;: u&#039;1&#039;, u&#039;notes&#039;: u&#039;dd&#039;, u&#039;stratify_base&#039;: 100, u&#039;active&#039;: 1, u&#039;metric_spec&#039;: u&#039;ddddddddddd&#039;}]<br />[0, False, {u&#039;input_value&#039;: 0, u&#039;input_type&#039;: u&#039;1&#039;, u&#039;notes&#039;: u&#039;ee&#039;, u&#039;stratify_base&#039;: 100, u&#039;active&#039;: 1, u&#039;metric_spec&#039;: u&#039;eeeeeee&#039;}]<br />

下面修改了 第三行

[4, 1, False]<br />[4, 2, False]<br />[1, 3, {u&#039;notes&#039;: u&#039;ccccccccccc&#039;, u&#039;metric_spec&#039;: u&#039;cccccccccccccccccccccccccccccc&#039;}]<br />[4, 4, False]<br />[4, 5, False]

单独修改 第三行 的  metric_spec

[4, 1, False]<br />[4, 2, False]<br />[1, 3, {u&#039;metric_spec&#039;: u&#039;ccccccccccccccc&#039;}]<br />[4, 4, False]<br />[4, 5, False]

[attachimg=1]

 

大概解读一下，修改后传入的  sale_order_contract_lines是一个  list ，
一行数据对应 一个元素

每个元素（行），又是一个列表，

此列表 为三个元素，
第一个  不明，
第二个 序号
第三个  如果 为 Fasle，说明改行没有修改，
    如果是一个字典，就是 被修改的字段名称，以及修改后 值

~~~~~~~~~~~~~~~~~~~



突然反映过来了，
我还煞有其事的 分析半天，这就是  接触过多次的东西，文档中有



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)

见笑了

不过留着吧 。

这次 之后，估计再也不会忘记了

嗯. 文档有这块儿的东西, 多留着吧...
