Hi mihir shah , Thanks for your immediate reply . I can understand your points . If you explain with some example it make more useful for me .. And once again thanks for your reply ... OMPRAKASH.A

Hi omprakash , for eg. If you are creating a customized module name school_management. in that first you create __init__.py file in that you import stu_reg ,after that __openerp_.py in this file you declare about all the views , dependencies ,(if any ) else always base. then you create stu_reg.py file name should be same as which is import in __init_.py file. In stu_reg.py file import fields ,osv and declare all the object models with there fields and data types . also you can define function if needed in stu_reg.py file

now create stu_reg.xml file for the view purpose.the structure of the xml view is given in documentation . so now when add this custom module to addons folder and try to install it , openerp by default first calls __init__.py file then __openerp__.py for initializing your module . hope my ans satisfying

Hi mihir shah , Thanks for your reply .Now i have idea about __init__.py file . But need more clarification please help me ... 1.) except import stu_reg , whether we will import another module ? If we import when ? And once again thanks for your reply ....OMPRAKASH.A

Hi omprakash, yes you can import n number of py files in __init__.py. after importing stu_reg i want to register teacher so i made tech_reg.py file. then i just have to import tech_reg in __init__.py file. But i would suggest that ..if you have different module for different business logic ,so as to use modular structure of openerp. and makes it more usable
