Hi,

Add a security folder for your module with 'ir.model.access.csv' file :-

In that file you can define access right for your own objects(objects that you created)

For Eg: with following content- ( assume that your object name is " demo " )

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink 

access_demo_users,demo.all.users,model_demo,base.group_user,1,1,1,1 

->make sure you added that file path in " openerp.py " file

Hope this helps...
