Hi all,

I have a custom module in hr , I want to set  'remarks' field set as read only for employees, and  I want to set read and write operation access  for manager user .How to achieve this task?

This is my code---------

lass hr_general(osv.osv):

_name = 'hr.general'

_columns = {

'name':fields.many2one('hr.employee','Name',required=True),

'state': fields.selection([('draft', 'To Submit'), ('reject', 'Rejected'), ('validate_hr', 'HR Approved'),('validate_mgr','Manager Approved')],'State'),

'description':fields.char('Subject',required=True),

'date_issue':fields.date('Date'),

'details':fields.text('Details',required=True),

'remarks':fields.text('Remarks')

}

_defaults={

'state':lambda *a: 'draft',

'date_issue': lambda *a: time.strftime('%Y-%m-%d %H:%M:%S'),

'name': lambda s, cr, uid, c: uid,

}

xml ---------------------

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

<field name="name">hr.general.form</field>

<field name="model">hr.general</field>

<field name="type">form</field>

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

<form string="Genaral" version="7.0">

<header>

<button name="action_button_manager" class="oe_highlight" states="draft" string="Manager Approval" type="object" groups="base.group_hr_user"/>

<button name="action_button_reject" string="Reject" type="object" groups="base.group_hr_user"/>

<button name="action_button_validate" states="validate_mgr" class="oe_highlight" string="HR Approval" type="object" groups="base.group_hr_user"/>

<button name="action_button_draft" string="Reset to Draft" type="object" groups="base.group_hr_user"/>

<field name="state" widget="statusbar" statusbar_visible="draft,reject,validate_hr,validate_mgr" statusbar_colors='{"draft":"blue","reject":"blue","validate_hr":"blue","validate_mgr":"blue"}'/>

</header>

<sheet>

<group>

<field name="name"/>

<field name="description"/>

<field name="date_issue"/>

<field name="details"/>

<field name="remarks"/></group>

</sheet>

</form>

</field>

</record>

=======================

 These are the existing groups ,so how to apply this groups to  my code  groups="base.group_hr_manager,base.group_hr_user,base.group_user"
