Guides: Explain reset_column_information in Chapter "Migrations and Seed Data"

[GitToTheHub]

The Chapter Migrations and Seed Data should add the explanation of reset_column_information.

I had 12 migrations to migrate in a production database and was wondering, why the migration was failing when setting reference data for existing data with the migration, after a new reference column was added with add_reference. The error was: ActiveModel::MissingAttributeError: can't write unknown attribute 'activity_id'
After executing rails db:migrate a second time, without changing something on the migration, the migration was successful.

In the Rails forum I found someone with the same Issue. The solution was to call reset_column_information on the table, which was modified before with add_column . For me the solution is to call it after add_reference .

This issue here is for documentation. I will make a PR for this.
