Hello,

In your class definition add these in .py,

class YourClass(models.Model):

    _name = "your.class"

    _description = "Your Class"

    _inherit = ['mail.thread', 'mail.activity.mixin', 'portal.mixin']

and in your manifest file make sure you have the correct dependency like,

'depends': ['base', 'mail',  'portal'],

and in your xml file after your sheet tag and this below div,

<record id="view_your_model_form" model="ir.ui.view">

            <field name="name">Your Model Form View</field>

            <field name="model">your.model</field>

            <field name="arch" type="xml">

                <form>

                    <header>

                    </header>

                    <sheet>

                                your field views....

                    </sheet>

                    <div class="oe_chatter">

                        <field name="message_follower_ids" widget="mail_followers"/>

                        <field name="message_ids" widget="mail_thread"/>

                    </div>

                </form>

            </field>

        </record>

In case if your doing it for any default tables of odoo, you should inherit and place the div in the view. Hope it work. Thanks 

Hi, 

To add chatter in your form view, you have to inherit the mail.thread class,

class YourClass(models.Model):

    _name = 'your.class'

    _inherit = ['mail.thread']

Now, add chatter widget in your XML file,

        <record id="view_your_class_form" model="ir.ui.view">

            <field name="name">your.class.form</field>

            <field name="model">your.class</field>

            <field name="arch" type="xml">

                <form>

                    <sheet>                    

                    YOUR CODE

                    </sheet>

                </form>

                <div class="oe_chatter">

                    <field name="message_follower_ids" widget="mail_followers"/>

                    <field name="message_ids" widget="mail_thread"/>

                </div>

        </record>

Thanks
