Odoo树视图仅显示一条包含计算的记录 [英] Odoo tree view only show one record with compute

问题描述

我试图在用户页面上显示用户签名的文档(来自"Sign app")，所以我将其添加到继承的模型中:

I'm trying to display a user signed documents (from the "Sign app") on his page, so I added this to the inherited model:

    x_signatures_relation = fields.One2many("signature.request.item", "partner_id")
    x_signatures = fields.One2many("signature.request", compute="_get_signed_documents")

    @api.one
    def _get_signed_documents(self):
        ids = []
        for signature in self.x_signatures_relation:
            ids.append(signature.signature_request_id)
        self.x_signatures = ids

"signature.request.item"是将伙伴(用户)与实际签名"signature.request"相关的表. 但是，即使当前用户有两个签名，这也会返回一个空视图，但是如果我替换了:

"signature.request.item" is the table relating the partner (user) with "signature.request" the actual signature. However this return an empty view even though the current user has two signatures, but if I replace :

self.x_signatures = ids

与:

self.x_signatures = ids[0]

或:

self.x_signatures = ids[1]

它显示记录，这是怎么回事?

It displays the record, so what's going on ?

推荐答案

Odoo有一组非常具体的规则，涉及如何允许"操作One2many和Many2Many字段.

Odoo has a very specific set of rules about how you are "allowed" to manipulate One2many and Many2Many fields.

请参见我最近的回答，其中详细说明了所有选项以及何时/如何使用它们. Odoo 文档也对此进行了解释也是

See my recent answer, which gives a detailed explanation of all options and when/how to use them. The Odoo documentation also explains it as well.

在您的情况下，您是在计算方法中设置值，因此您想完全替换所有现有值.

In your case, you are setting the value in a compute method, so you want to completely replace any existing values.

# Instead of 
# self.x_signatures = ids
# Try this, which uses the special number 6 to mean
# "replace any existing ids with these ids"
self.x_signatures = [(6, 0, ids)]

此外，您可以简化计算方法:

Furthermore, you could simplify your compute method:

@api.one
def _get_signed_documents(self):
    self.x_signatures = [(6, 0, self.x_signatures_relation.ids)]
