- 2. In Odoo 16, adding a store attribute to a field allows you to optimize the performance of your application by controlling how data is stored and retrieved from the database. The store attribute specifies whether the field's value should be stored in the database or computed on-the-fly when accessed.
- 3. Here are some common use cases of store attribute: • Search and filter optimization: Storing a field enables faster searching and filtering operations in Odoo, improving query performance. • Aggregated computations: Storing a field allows for efficient calculations and aggregations, saving processing time when retrieving total values or performing calculations. • Reports and analytics: Storing frequently used fields speeds up report generation and data analysis by eliminating the need for on-the-fly computations. • Data synchronization with external systems: Storing fields simplifies data exchange with external applications, facilitating synchronization tasks. • Performance optimization for large datasets: Storing certain fields enhances performance by minimizing on-the- fly calculations, resulting in faster data retrieval and manipulation operations.
- 4. Let’s discuss how the store attribute works: The image above shows the two fields we defined for the user and their login information.Because we designated it as a related field, the login field is immediately filled when we select a user. In Odoo, related fields and computed fields are not kept in the database; to do so, we must define store=True in a field.
- 5. Let’s take a look how we can store a field via XML, The image above illustrates that we can define force_save="1" in a field to allow for the storage of a field in a database using XML. This way we can store fields in database.
