Hi!

I have a model with a Many2Many 'ir.attachment' field. The implementation in BackEnd is working as expected and the widget in the form is perfect. Now i need to implement a Portal form view and a Portal detail view (FrontEnd), it is implemented for all the fields but 'file_ids', i can not find the widget docu for the portal.

I checked the docu :

• https://www.odoo.com/documentation/12.0/reference/javascript_reference.html#relational-fields

Also checked:

• https://github.com/odoo/odoo/blob/12.0/odoo/addons/base/views/ir_qweb_widget_templates.xml

But just found "contact" template

Model

from odoo import fields, models, api
class MyModel(models.Model):
    _name = 'mymodule.mymodel'
    _inherit = ['mail.thread', 'mail.activity.mixin', 'portal.mixin']
    _description = 'My Model'
    _order = 'create_date desc'
    _rec_name = 'name'

    name = fields.Char()
    description = fields.Char()
    file_ids = fields.Many2many(comodel_name='ir.attachment', string='Files')

View

<?xml version="1.0"?>
<odoo>
  <record id="view_mymodule_mymodel_form" model="ir.ui.view">
    <field name="name">MyModel Form</field>
    <field name="model">mymodule.mymodel</field>
    <field name="arch" type="xml">
      <form string="MyModel">
        <sheet>

          <field name="id" invisible="1"/>
          <group name="group_data" col="1">
            <group col="4">
              <field name="name"/>
              <field name="description"/>
            </group>
          </group>

          <field name="file_ids" widget="many2many_binary"/>

          <div class="oe_chatter">
            <field name="message_follower_ids" widget="mail_followers"/>
            <field name="message_ids" widget="mail_thread"/>
          </div>

        </sheet>
      </form>
    </field>
  </record>
</odoo>

Controller

from odoo import http, _
from odoo.addons.portal.controllers.portal import CustomerPortal

class MyModelCustomerPortal(CustomerPortal):
    @http.route(['/mymodule/mymodel/edit/<model("mymodule.mymodel"):mymodel>'], type='http', auth='user', website=True)
    def mymodel_portal_edit(self, mymodel, **post):
        if post:
            mymodel.sudo().write(post)
            return http.request.redirect('/mymodule/mymodel/view/%s' % slug(mymodel))
        response = http.request.render("mymodule.mymodel_portal_edit", {'mymodel': mymodel})
        return response

    @http.route(['/mymodule/mymodel/view/<model("mymodule.mymodel"):mymodel>'], type='http', auth='user', website=True)
    def mymodel_portal_view(self, mymodel, **post):
        response = http.request.render("mymodule.mymodel_portal_view", {'mymodel': mymodel})
        return response
