Odoo 12 在尝试从记录中访问模型记录时出现 TypeError

如何解决Odoo 12 在尝试从记录中访问模型记录时出现 TypeError

我正在尝试制作一个简单的控制器，它使用 Python 在 Odoo 12 中返回一个 json 对象。我一直在学习几个教程，但每次尝试使用 env['product.template'] 时我都会遇到相同的错误。这是我的控制器代码。

import odoo.http as http
from odoo import SUPERUSER_ID
from odoo import registry as registry_get
from odoo.api import Environment
import json


class Controller(http.Controller):

    @http.route('/test',type='http',auth='public',website=False)
    def handler(self):
        registry = registry_get('ceres')
        with registry.cursor() as cr:
            env = Environment(cr,SUPERUSER_ID,{})
            attendee = env['product.template'].sudo().search([])
        return attendee 

这是我在调用控制器时收到的异常：

解决方法

您需要返回 html 响应

from odoo.http import request
import odoo.http as http
from odoo import SUPERUSER_ID
from odoo import registry as registry_get
from odoo.api import Environment
import json


class Controller(http.Controller):

    @http.route('/test',type='http',auth='public',website=False)
    def handler(self):
        registry = registry_get('ceres')
        with registry.cursor() as cr:
            env = Environment(cr,SUPERUSER_ID,{})
            attendee = env['product.template'].sudo().search([])
        response = request.make_response(attendee)
        return response 

,

您可以将 route 类型更改为 json 并返回一个 dict 或一个 JSON 对象。

在以下示例中，我们使用 json 对象返回每个产品的 name 和 list_price：

class Controller(http.Controller):

    @http.route('/test',type='json',website=False)
    def handler(self):
        records = request.env['product.template'].sudo().search_read([],fields=['name','list_price'])
        return json.dumps({r['id']: r for r in records}) 

您可以使用 web.ajax 来调用它：

var ajax = require('web.ajax');
ajax.jsonRpc('/test','call',{}).then(function (data) {
    
});

演示数据库中返回值的示例：
