Django ORM (Object-Relational Mapping) is a tool that provides a high-level, Pythonic interface for working with relational databases. The ORM allows developers to interact with the database using Python code instead of SQL statements.
There are several methods available in the Django ORM for retrieving data from the database. Here are some of the commonly used methods:
This method retrieves a single record from the database that matches the specified condition. For example, MyModel.objects.get(id=1) would retrieve the record from the MyModel table where the id column equals 1.
This method retrieves all records from the specified table. For example, MyModel.objects.all() would retrieve all records from the MyModel table.
This method retrieves all records from the specified table that match the specified condition. For example, MyModel.objects.filter(name='John') would retrieve all records from the MyModel table where the name column equals 'John'.
Here is an example of how these methods can be used to retrieve data from a database:
from myapp.models import MyModel
# Retrieve a single record from the database
record = MyModel.objects.get(id=1)
# Retrieve all records from the database
records = MyModel.objects.all()
# Retrieve all records from the database that match a specific condition
filtered_records = MyModel.objects.filter(name='John')In addition to these methods, there are other methods available in the Django ORM for more complex queries, such as exclude(), order_by(), annotate(), and aggregate(). The Django ORM also supports raw SQL queries if needed.
Overall, the Django ORM provides a simple and convenient way to work with relational databases in Python, allowing developers to write database queries in a more Pythonic and readable way.
