What is context and life cycle of context in Odoo!

What Is Context In Odoo?

In Odoo, the context is a Python dictionary that contains information about the current execution environment. It is commonly used to pass parameters and configuration data between different parts of the application.

The context dictionary can contain a variety of information such as:

• User information: The user ID, user preferences, and security groups.
• Company information: The company ID, currency, and other configuration data.
• Language and time zone information: The language code and time zone for the current user.
• Other parameters: Custom parameters specific to the current operation or module.

The context is usually passed as a parameter to Odoo methods and functions, and can be modified by adding or updating key-value pairs. The modified context is then passed on to other methods or functions, allowing for the sharing of information throughout the application.

The context is an important tool for customizing the behaviour of Odoo modules and can be used to implement a wide variety of features, from dynamic filtering of records to language-specific formatting of data.

Life Cycle Of Context In Odoo

In Odoo, the life cycle of context refers to how the context dictionary is passed and modified throughout the execution of a module or application. The context is a Python dictionary that contains information about the current environment, such as the user, company, language, time zone, and other data that can be used by the application.

The life cycle of context can be divided into three main stages:

1 Initialization: At the beginning of each request, Odoo initializes a new context dictionary with default values. These values can be defined in the code or in the configuration file.

2 Modification: During the execution of the application, the context dictionary can be modified by adding, updating, or deleting key-value pairs. This is usually done in response to user actions or business logic.

3 Passing: The modified context dictionary is passed to other functions or methods within the same module or across different modules. This allows for the sharing of information between different parts of the application.

It's important to note that the context dictionary is not persistent and is created and destroyed for each request. Therefore, any modifications made to the context will not persist between requests.
