How to alter a column name in an Ecto model with a migration?

Does anyone know of (or can provide) an example of how to alter a table column name using the ecto DSL

I'm guessing I just use mix ecto.gen.migration but then would I just fill in the empty created file with my custom code (if so, how would you edit a column name, the docs show modify to change the column type)

or is there a command line flag I can pass to generate the migration code for me?

Solution

  • You can now do that with Ecto.Migration.rename/3:

    rename table(:posts), :title, to: :summary
