Odoo 9 Is there a way to handle authorization with different groups on a certain field in form view?

Question

I'm trying to create a form view.

<field name="is_positive" attrs="{'readonly':[('state','==','final')]}"/>

However there is many attributes like groups and invisible related to authorization so that certain group of people can see the field.

groups="base.group_hr_user"

But Is there a way for certain group can edit the field and the other group cannot?

Answer 1

First of all, you cannot use a domain like this one

<field name="is_positive" attrs="{'readonly':[('state','==','final')]}"/>

There is not a '==' operator, use = instead.

Now, to answer your question, if you want to create a special view for another group in which some elements are readonly for one group, and editable in the other, you have to it this way.

For the default view :

<record id="some_model_view" model="ir.ui.view">
    <field name="name">some.model.form</field>
    <field name="model">some.model</field>
    <field name="arch" type="xml">
        <form>
             <field name="some_field" readonly="1"/>
        </form>
    <field/>
</record>

For a certain group :

<record id="some_model_view_for_other_group" model="ir.ui.view">
    <field name="name">some.model.form</field>
    <field name="model">some.model</field>
    <field name="inherit_id" ref="my_module.some_model_view"
    <field name="groups_id" eval="[(6, 0, [ref('some.first_group')])]" />
    <field name="arch" type="xml">
        <field name="some_field" position="attributes">
            <attribute name="readonly">0</attribute>
        </field>
    <field/>
</record>
