OpenERP唯一约束

Question

我在OpenERP/PostgreSQL中有一个表,其中包含以下列:name和description.

我为唯一名称添加了以下验证:

_sql_constraints = [('unique_name', 'unique(name)', 'A record with the same name already exists.')]

它工作正常,但它区分大小写.目前,它接受诸如"Mickey","MICKEY"和"mickey"之类的值:

Wrong Way:
--------------------------
| name   | description   |
--------------------------
| mickey | not a mouse   |
--------------------------
| MICKEY | not a mouse   |
--------------------------
| Mickey | not a mouse   |
--------------------------

有没有办法修改验证代码,以便它不允许用户添加几个值,如"米奇","MICKEY"和"米奇"？如何使唯一密钥验证不敏感？

Right Way:
--------------------------------
| name         | description   |
--------------------------------
| mickey       | not a mouse   |
--------------------------------
| mickey mouse | is a mouse    |
--------------------------------
| donald       | is a duck     |
--------------------------------

Answer 1

要case insensitive constraints查看HERE ,您可以随时使用Openerp Constraints而不是SQL.

对于openerp约束

检查示例

def _check_unique_insesitive(self, cr, uid, ids, context=None):
    sr_ids = self.search(cr, 1 ,[], context=context)
    lst = [
            x.FIELD.lower() for x in self.browse(cr, uid, sr_ids, context=context)
            if x.FIELD and x.id not in ids
          ]
    for self_obj in self.browse(cr, uid, ids, context=context):
        if self_obj.FILD and self_obj.FILD.lower() in  lst:
            return False
    return True

_constraints = [(_check_unique_insesitive, 'Error: UNIQUE MSG', ['FIELD'])]
