I am using odoo 9 and have created a module name 'custom_webpage' and inherited 'website' model.

There is a field in 'website' module named 'social_twitter'. I need that value in JS.

Now in my custom module JS file I can't bring the value. I tried:

openerp.website.Model

It shows openerp not found error.

I tried:

openerp.website = function(instance) { };

It shows instance not found error.

Can anyone please tell me how can I get the value of social_twitter in js? I need to take the value from the field, split it and show it on the website with JS.

You can get the value through many ways

First way is

from openerp import models, fields 

class YourModel(models.Model):
    _name = 'your.model' 
     
     def your_function(self):
         # CODE TO GET VALUE
          return value

odoo.define('custom_webpage.my_js', function (require) {'use strict';
    var Model = require('web.Model');

    (new Model('your.model')).call('your_function').then(function (your_return_value) { 
         console.log(your_return_value);
    });

});

Second way

from openerp import http 

class YourModel(http.Controller): 
    @http.route(['/action_get_social_twitter'], type='json', auth="public") 
    def get_social_twitter(self, **post): 
        # CODE TO GET VALUE          
        return value

odoo.define('custom_webpage.my_js', function (require) {'use strict';
     var ajax = require('web.ajax'); 
     ajax.jsonRpc("/action_get_social_twitter", 'call').then(function(your_return_value){ 
            console.log(your_return_value);
    }); 
})

Thanks for the reply, I didn't understand the PY part. I need the value only in JS.

Why I need to write py function and isn't there any way to get the field value from model field to js?

regards.

Python function is needed because js wan't to call a python function.

Getting value without python is possible.

but this is simple

You try ,It will help you

Ok, now I understand.

I will return a value in python function. JS will call that function and get that value.

In your first JS snippet you wrote 'custom_webpage.my_js' . What is my_js here?

Thanks.

Shameem Babu

my_js is the name of your js.

you can give the same name of js file.

I have posted my code with an error in the answer section, please have a look.

Shameem Babu

It is the mismatching of python function arguments .

add @api.one

@api.one

def your_function(self):

add cr, uid etc

def your_function(self, cr, uid, ids, context=None):

or follow second step

I have used models.Model so can't use Cr,uid,ids..

@api is not working for some reason.

I am trying to use second method. But http controller shows no value.

I used post.get('social_twitter'). Is that the correct way to get data of a model for a field?

Shameem Babu

in second method, did u ensure that the function is working ?

from openerp.http import request

use request.env['your.model'].search([)]) to get all objects of model

Thanks :D

I got this with following:

class website(http.Controller):

@http.route(['/action_get_value_to_website'], type='json', auth="public")

def get_value_to_website(self, **post):

cr, context, pool = request.cr, request.context, request.registry

website = pool.get('website')

hr_employee_ids = website.search(cr, SUPERUSER_ID, [], context=context)

twitter_data = website.browse(cr, SUPERUSER_ID, hr_employee_ids, context=context).social_twitter

value = twitter_data

return value

Following your guidelines, I succeeded to pass a value defined in a controller to JS and log it into the console.

How would you get the same value available in a Qweb template in Odoo 10 and call it via <t t-esc="value"/>?

my file models named models.py

from odoo import models, fields, api

class api_conector(models.Model):

_name = 'api_conector.api_conector'

def my_function(self):

valor = "call to function suscesfully"

return valor

mi file JS

odoo.define('api_conector.api_conector', function (require) {'use strict';

varModel = require('web.Model');

(new Model('api_conector.api_conector')).call('my_function').then(function (valor) {

console.log(valor);

});

it does not work

what am I doing wrong?

I have wrote this:

Py file

def get_value_to_website(self): 
    value = self.social_twitter 
    return value

JS file:

odoo.define('custom_webpage.custom', function (require) {'use strict';
 
   var Model = require('web.Model');

 
   (new Model('website')).call('get_value_to_website').then(function (value) { 
        console.log(value);
 
   });


});

I am getting this error in console:

Server application error .......
return getattr(request.registry.get(model), method)(request.cr, request.uid, *args, **kwargs)\nTypeError: get_value_to_website() takes exactly 1 argument (3 given)\n","exception_type":"internal_error","message":"get_value_to_website() takes exactly 1 argument (3 given)","name":"exceptions.TypeError","arguments":["get_value_to_website() takes exactly 1 argument (3 given)"]}}
