odoo10 many2one字段下拉更多选项时自定义排序方法

Posted 2020-11-26 pywjh

背景：

一个many2one字段，在界面上下拉选值的时候，有一个打开弹窗选择的页面，有时候需要对这个数据排序，方便用户使用。

思路：

需要搞清楚的一点就是：点击这个many2one字段，默认会发送一个search_read请求，我们需要做的就是在这个过程中传递一个消息告诉odoo到这个位置了，需要排序了。当然，这个消息的发送，就可以用conext来传递。

实现：

在xml中对应的字段中设置conetxt

<field name="budget_item_id" context="{‘budget_item_order‘: True}"/>

这里给预算项目字段一个上下文：budget_item_order为True

然后在对应模型的py文件中编写search_read方法:

@api.model
def search_read(self, domain=None, fields=None, offset=0, limit=None, order=None):
    # if not domain:
    #     domain = []
    # domain += self._get_domains()
    # if self.env.context.get(‘budget_control_rule‘, False):
    #     order = ‘code‘
    if self.env.context.get(‘budget_item_order‘, False):
        order = ‘order‘
    return super(KthrpBudgetBudgetItem, self).search_read(domain=domain, fields=fields, offset=offset,
                                                              limit=limit,
                                                              order=order)
注： 不知道只写着一个方法会不会生效，下面有全部的方法，不生效尝试下面的5个方法同时写

    def _get_domains(self):
        domain = []
        if self.env.context.get(‘budget_control_rule‘, False):
            domain += [(‘company_id‘, ‘in‘, (False, self.env.user.company_id.id)),
                       (‘business_group_id‘, ‘=‘, self.env.user.company_id.business_group_id.id)]
        budget_category_company = self.env.context.get(‘budget_category_company‘, False)
        if budget_category_company:
            company_id = budget_category_company[1]
            business_group_id = budget_category_company[0]
            if company_id:
                domain += [(‘company_id‘, ‘in‘, (company_id, False))]
            else:
                domain += [(‘business_group_id‘, ‘=‘, business_group_id)]
        select_depend_type_id = self.env.context.get(‘select_depend_type_id‘,False)
        if select_depend_type_id:
            budget_item_ids = self.env[‘kthrp.budget.budget.sheet.document.type‘].browse(select_depend_type_id).budget_item_ids.ids
            if budget_item_ids:
                domain += [(‘id‘,‘in‘, budget_item_ids)]
?
        return domain
?
    @api.model
    def name_search(self, name, args=None, operator=‘ilike‘, limit=100):
        args = args or []
        domain = self._get_domains()
        return super(KthrpBudgetBudgetItem, self).name_search(name, args=args + domain, operator=operator, limit=limit)
