Method to Store Models in CSV File

As a backend developer,

I want to develop a method that can store a set of model instances in a CSV file,

So that I can efficiently add, create, or update records in a structured format, enhancing data management and persistence within our application.

Acceptance Criteria

• Given a collection of model instances that need to be persisted,
  When I invoke the method with the option to add new records,
  Then the method should append the model instances as new lines in the CSV file without altering existing data.

• Given a need to create a new CSV file from a set of model instances,
  When I invoke the method with the option to create a file,
  Then it should generate a new CSV file, including headers that match the model's properties, and populate it with the data from the model instances.

• Given existing records in a CSV file that need to be updated with new data from model instances,
  When I invoke the method with the option to update records,
  Then it should match model instances to records based on a unique identifier and update the records in the file accordingly.

• Given the method is handling data with special characters or formats that may conflict with the CSV format,
  When model instances are being converted to CSV lines,
  Then the method should correctly escape or handle these characters to preserve the integrity of the data and the CSV structure.

• Given concurrent operations that might lead to race conditions or data integrity issues,
  When the method is invoked by multiple processes or threads,
  Then it should implement appropriate locking or concurrency control mechanisms to ensure data consistency and prevent corruption.
