Exporting DBT to a CSV File

Using Django ORM and Python CSV Library

To export data from a Django model to a CSV file, you can utilize the Django ORM to retrieve all the data you wish to export. This is done by using the values_list method on the model's queryset to get all the necessary data in an iterable form. Then, with the Python csv library, you can write this data to a CSV file. The csv library provides functionality for handling CSV file creation and manipulation, allowing for the data to be formatted and saved in the CSV format.

Using StringIO for File Handling

During the CSV file creation process, the StringIO module can be employed to handle the CSV data as a file-like object. This is useful for situations where you might want to work with CSV data in memory before saving it to the filesystem or sending it over a network. StringIO acts as an in-memory stream for text data, which the csv library can use to write to and read from, just like it would with a regular file.
