I make a new field in res.user called user_new_option and I want to add this value in the
XML context
<record model="ir.actions.act_window" id="model_user_new">
<field name="name">model.user.new</field>
<field name="res_model">model.user.new</field>
<field name="view_mode">tree,form</field>
<field name="context">{'user_new_option': uid}</field>
</record>
how can I do this.
