1. Building a Module in Odoo 16

2. As we all know Odoo is basically a web based open source
platform which act as a solution for all business
requirements and Odoo module is a set of business logic
which helps to enhance the excessive functionality or to
add some new functionality in order.In this slide we can
check how to create a module “School Management” in
Odoo 16.

3. • First we need to create a custom directory [ here we named as custom addons].
• Inside this we can create the modules that we needed and then add its path along
with addons path in odoo.conf
• Then we create a module inside custom addons named school_management
which helps to create the records of student admission in a school.
• Inside the school_management create python file named __init__.py which is the
python module discriminator file where we can load the python packages that
needed for this module.
• Then we create another python file named __manifest__.py which is the metadata
of the module and this file helps to show the module name on the Odoo app list.

4. • Then create a directory named models which is used to create business objects.ie,we can
add new business objects or we can inherit current business objects that in the default
Odoo.
• In the model directory we are creating the python file __init__.py that is used to load the
python files that is used in the models.
• Next python file creating is school.py
• Here in this file , we will define the models and fields to store the data into the
database.So let our model be school.student,This will create a table in the database and
we have to define the fields to accept the values.
• To store values, we have to define different fields. There are different types of fields such
as char, int,many2one,one2many, date, etc. In the school management, we need a name,
class, division.

6. • Next,we need to define the views so that it can be seen in the odoo users interface.For
that we can create a directory ‘views’.
• Inside the folder we create a file named school.xml file.Inside this file we can add
menuitem of the school ,Actions and views that we needed for the school management
module.
• Here we create Main menu as school_menu and the subsequent menu as school_exams
menu.Also defined its actions.

8. • Next we define the basic view for that particular model.

9. • Now lets create a security file under the module.In the security folder we place all the files
related to the security.Here we have to create a csv file named ‘ir.model.access.csv’.
• At this file we can declare the access for each model for which of the users who have
permission to read , write or edit that particular object.

10. ● Next we can move to the Manifest file which is the metadata of the module and it has
some required fields as
○ Name - Name of the module.
○ Description - Brief description of the module.
○ Version- Here, we can specify the module version.
○ License - Specify the distribution license
○ Author - Author name of the module.
○ Website - Module author’s website URL.
○ Category - Specify the category name.
○ Depends - specify the list of modules that must installed before installing the module.
○ Data - With the installation of the module, these files are installed or updated.
○ Demo - In active demonstration mode, the data files that are installed or updated.

12. Now you just restart your odoo service and activate the developer mode and click on the
Apps → Update Apps List → Update

13. Once you click on the update button ,search for our model that we have created and the click
on the install button.

14. Now we can see the parent menu School.

15. • Click on the Main menu we can see the submenu School.
• Here you can create the record
