Question 1

How to integrate Seed Fu with Capistrano for automated seeding?

Accepted Answer

Require 'seed-fu/capistrano' in config/deploy.rb for Capistrano 2, or 'seed-fu/capistrano3' for Capistrano 3, then hook it to deploy tasks like 'deploy:publishing' to run seeds during deployment.

Question 2

Seed Fu vs Rails default seeds.rb: which is better?

Accepted Answer

Seed Fu is superior for idempotent seeding with update capabilities using constraints, preventing duplicates. Rails' seeds.rb is simpler but prone to errors if run multiple times without manual checks.

Question 3

How to handle large seed files with millions of rows in Seed Fu?

Accepted Answer

Use Gzip compression (.rb.gz files) and add # BREAK EVAL comments in fixtures to avoid loading entire files into memory, as recommended in the README for performance.

Question 4

Can Seed Fu update existing records based on multiple columns?

Accepted Answer

Yes, specify constraints like seed(:x, :y) to identify records by those columns, allowing updates to attributes while preventing new duplicates from being created.

Question 5

How to generate seed files from a CSV using Seed Fu?

Accepted Answer

Use SeedFu::Writer to programmatically create seed files: load CSV data, iterate rows, and output seed syntax with the writer, which can include breaks for memory management.

Question 6

Is Seed Fu compatible with Rails 6 or newer versions?

Accepted Answer

The README lists support only up to Rails 5.0; for newer Rails versions, check GitHub issues or community updates, as compatibility may require patches or forks.
