Backfill script in Phoenix

Hello I added a new table on one of my columns and use the functions inside my app to query an API to insert the correct value in the column.

I created a backfill script (an Elixir module) – or my best attempt at one. How do I test this development? Where exactly do I put it?

what does this means?

backfill script? what is this?

At least You should provide the code for this module.

I figured it out by tinkering. Will be better about providing context on this website. I’m sorry.
