Introduction To ORM Methods In Odoo18
Understanding and practicing the basic ORM methods in Odoo18, one can experience complete Odoo at its best for creating a new record, querying data, simplifying database operations, increasing efficiency, and making application development easier In this blog, we will get a head start on Knowing the basic Odoo18 ORM functions in , and start discovering more about the Odoo18 ORM methods that can amaze you about Odoo 18 for your ERP Implementation projects
The foundation of relating with the database in Odoo is given by ORM (Object-Relational Mapping) techniques, which let developers efficiently add, read, edit, and remove entries from the models. By abstracting away the intricacy of SQL queries, these ORM techniques let developers concentrate on business logic instead of database administration.
Essential ORM Functions
Create
Model.create(vals_list)
- Takes a dictionary of values in a list and returns a recordset (a list of newly created records).
- For Creates new database entries;
new_record = self.env['model.name'].create({
'field_1': value_1, 'field_2': value_2,})
Copy
For making duplicates of documents
With this method, you can modify or remove fields that shouldn’t be replicated while still creating a new record with the same data as the original.
Model.copy (none by default)
new_record = record.copy(default=None)
Write
This method assigns values to existing records.
model.write(vals)
In the above example, you will see that the key value ’email updates the field for the record of a partner.
partner.write({ 'email': 'newmail@example.com', });
Browse
This step retrieves the details of one such model to which access has been granted. It will subsequently use the ID’s assigned through arguments as a base for retrieving database records where details are fetched.
Such an example includes: browse([ids]?). For all records regarding the
If the above demonstration is there, it will print a record because there is id, which is the partner ID in the field res.partner.
partner = self. env['res.partner'] .browse (partner_id);
Search
Gets multiple records that match against specific criteria. Returns the available ones.
Using an example Jeff on partner name, this search is using the res.partner instance for matching records.
domain[,offset=0] [,limit=none[,set=none]; Ideal.Search
Using an empty list that is to match the current records.
partner = self. env['res.partner'] .browse (partner_id);
SearchCount
Returns the count of the records matching the specified field.
This function returns the quantity of records that are active in the res.partner instance of the instance.
first = self.env['res.partner'] search_count([('work', '=', true)])
Read
Reads a specific field in a record structure and returns a list of dictionaries with field values.
[Fields] In Model.read
In the example, partner_data would be all partner records listed with name, email address, and field values.
partner_data = partner.read(['name', 'email'])
Unlink
Remove records from the database; in the example, this means deleting the row of the partner record. It is important to use this method with caution as it deletes records on a regular basis.
partner.unlink() .
Flush
Any pending changes to the current transaction should be written to the database user immediately.
Map
Mapped retrieves the values of a given field from a recordset. In the example, it is retrieving the invoice_ids of each record in the sale.order model.
invoices = self.env['sale.order']. mapped('invoice_ids')
Sort
To sort a recordset by specific fields, use the sorted() function, which returns a new recordset sorted by the field of interest. In the example, the line_ids are sorted by the product names in each line.
self.line_ids = self.line_ids.sorted(key=lambda x: x.product_id.name)
Data handling is made easy with simple methods like create, write, and unlink. The complex methods such as search, read, and browse will help query the database in an efficient manner and get the desired records. It is through mapped and sorted that developers dynamically manage record sets and get to do lots of complex work easily. ORMS in Odoo18 brings an enormous increase in the productivity of developers and allows them to focus on logic related to business rather than getting themselves entangled with all database complexities, thus forming a very important part of a framework.
