Understanding ORM in Odoo
ORM (Object-Relational Mapping) allows developers to interact with the database using Python classes and methods instead of raw SQL queries. This simplifies the data-handling process, making it more readable and maintainable. In Odoo 18, the ORM methods provide a range of functionalities, such as creating, reading, updating, and deleting records. These methods are central to most of Odoo’s operations and are critical for anyone working with odoo consulting services or odoo development company projects.
By using ORM methods, developers can handle complex data structures and relationships while keeping code consistent, modular, and reusable. This is particularly valuable in professional odoo customization services, where unique business processes often require custom database interactions.
Key ORM Methods in Odoo 18
Let’s dive into the main ORM methods that Odoo 18 offers, each serving a specific purpose in database operations.
1. Create Method
The create() method is fundamental in Odoo’s ORM, used to add new records to the database. For instance, when a new sales order or customer is created in the system, the create() method is called to insert that data.
Example:python
new_record = self.env['model.name'].create({
'field_name': value,
})
This method allows for customization of data inputs, which is essential for odoo development services that focus on tailored business processes.
2. Search Method
The search() method is another critical ORM function, allowing developers to locate records based on specific criteria. It accepts parameters that can define complex search conditions, making it highly versatile in retrieving data.
Example:python
records = self.env['model.name'].search([('field_name', '=', value)])
This method is especially useful in odoo consulting services, where tailored reporting or filtering is required, allowing businesses to access data efficiently.
3. Read Method
The read() method is utilized to fetch specific fields from a record, enabling developers to retrieve data in a controlled manner. It allows selective access to a record’s attributes, which can improve performance by avoiding unnecessary data retrieval.
Example: python
record_data = records.read(['field1', 'field2'])
For odoo customization services, this method ensures that only the relevant information is displayed, helping in creating more user-friendly and performant applications.
4. Write Method
Used to update existing records, the write() method is essential for modifying data already present in the database. When users need to make changes to records—such as updating a customer’s address or modifying a product’s price—the write() method comes into play.
Example: python
record.write({
'field_name': new_value,
})
The write() method is vital in odoo development company projects where continuous data adjustments are required. It allows businesses to keep information up-to-date without extensive code rewriting.
5. Unlink Method
The unlink() method is used to delete records from the database. While it should be used carefully to avoid accidental data loss, it’s crucial for cleaning up unnecessary or outdated records.
Example: python
record.unlink()
For odoo development services, this method is particularly beneficial in ensuring that database clutter is minimized, making data easier to manage and more efficient to process.

6. Search_Count Method
When the goal is to count records instead of fetching them, the search_count() method is perfect. This method saves resources by returning only the number of matching records, rather than the records themselves.
Example: python
count = self.env['model.name'].search_count([('field_name', '=', value)])
In odoo erp development company scenarios, where data analytics or record summaries are required, this method becomes invaluable, offering quick insights without database strain.
7. Browse Method
The browse() method retrieves records based on their unique IDs, providing direct access to specific entries. It’s particularly useful when handling multiple records with known IDs.
Example: python
record = self.env['model.name'].browse(record_id)
The browse() method supports both odoo application development and odoo app development services, as it enables efficient record access, simplifying complex data-handling operations.
8. Copy Method
The copy() method is ideal for duplicating records, especially when similar data structures are required. It automatically duplicates fields but can be adjusted as needed.
Example: python
new_record = existing_record.copy()
For odoo erp development services, this method is invaluable when replicating entries is essential, such as generating similar product lines or service offerings.
9. Name_Get and Name_Search
The name_get() and name_search() methods are used for representing records in a user-friendly manner. name_get() returns the display name for records, while name_search() facilitates search operations by name.
Example: python
record_name = record.name_get()
These methods are essential for odoo crm consultants or any odoo services provider focusing on improving end-user experience, as they enable more intuitive database interactions.
Advanced ORM Techniques in Odoo 18
In addition to the basic methods, Odoo 18 provides advanced ORM techniques that allow developers to perform operations more efficiently and innovatively. For example, the filtered() method can further refine results obtained by search(), offering a streamlined approach to data filtering. Similarly, the sorted() method enables sorting of records based on specific criteria, such as date or quantity.
Using these advanced methods can significantly enhance odoo consulting services by allowing a deeper level of data manipulation and analysis. This makes Odoo a preferred choice for odoo erp implementation projects, where complex data structures and extensive customization are often required.
