First of all you have to define a new Object. You can do that by adding your custom module.
Eg for new object:- file is ” custom_test.py”
from osv import osv,fields
from openerp.tools.translate import _
class custom_class(osv.osv):
_name=’custom.class’
_columns={
‘names’ : fields.char(‘Name’, size=128, required=True),
‘class’ : fields.char(string=’Class’, required=True),
‘code’ : fields.char(string=’Code’),
}
custom_class()
class custom_subject(osv.Model):
_name = “custom.subject”
_description = “Subjects”
_columns = {
‘name’: fields.char(‘Name’, size=64, required=True),
‘code’: fields.char(‘Code’, size=12, required=True),
‘maximum_marks’: fields.integer(“Maximum marks”, size=5),
‘minimum_marks’: fields.integer(“Minimum marks”, size=5),
‘weightage’: fields.integer(“Weightage”, size=10),
‘is_practical’:fields.boolean(‘Is Practical’, help=’Check this if subject is practical.’),
‘no_exam’ : fields.boolean(“No Exam”, help=’Check this if subject has no exam.’),
}
custom_subject()
Then you have to define your view file
Steps to add menu item:-
1. define your menu item
Eg:
<menuitem icon=”terp-project” id=”my_test_menu” name=”My Test” sequence=”4″ action=”action_my_form”/>
**This is your main menu item that shows in your tab
2. define your action
Eg:
<record model=”ir.actions.act_window” id=”action_my_form”>
<field name=”name”>Class</field>
<field name=”res_model”>custom.class</field>
<field name=”view_type”>form</field>
<field name=”view_id” ref=”my_test_form” />
<field name=”view_mode”>tree,form</field>
</record>
**here i defined action for my main menu item and specified its view types
3. then you can link your views to action
Eg:
<record id=”action_my_form_tree” model=”ir.actions.act_window.view”>
<field name=”view_mode”>tree</field>
<field name=”view_id” ref=”my_test_tree”/>
<field name=”act_window_id” ref=”action_my_form”/>
</record>
**here i linked my tree view to action, you can link your each view like this,ie form,search etc….
My custom view file “custom_test_view.xml” as follows:
<?xml version=”1.0″ encoding=”utf-8″?>
<openerp>
