Hello, I am new to odoo, for my custom module I need to send a single email to all my selected res.partners from tree view. After selecting records, I have used mail.mail to send emails but when i click on send email action my mail.mail form do no show any data in email_to field and i had to fill that field explicitly for every record i wanted. Would you please help me to know how to select multiple entries from a tree view for my email_to field or is their any other way to achieve this.
here is my Act_window code from view.xml
<act_window id="Identifier"
name="Send E"
src_model="res.partner"
res_model="mail.mail"
view_mode="form"
multi="True"
target="new"
key2="client_action_multi"
context="{'default_email_to': '${object.id or \'\'}'}"/>
