I'm running Rails 5.0.6, and I can't Google myself to any other occurences of this problem.
The migrations fail when I have a migration that inserts data into a table, that has data for a column that was added in a previous migration file executed by the same migrate command Basically I have 3 migrations that are run with the following command rails db:migrate first migration chronologically: create_table :campaign_orders do |t| t.integer :order end second migration: add_column :campaign_orders, :priority, :integer third migration: CampaignOrder.create(order: 0, priority: 1) The third migration fails, if all migrations are outstanding when running migrate command, but succeeds if you run the migrate command again. It fails with the following error: > rails aborted! > StandardError: An error has occurred, all later migrations canceled: > unknown attribute 'priority' for CampaignOrder. > /Users/tomwilliams/Projects/incard-rails/db/migrate/20190326143614_insert_accepted_email_campaign.rb:66:in > > `up' > /Users/tomwilliams/Projects/incard-rails/bin/rails:9:in `require' > /Users/tomwilliams/Projects/incard-rails/bin/rails:9:in `<top (required)>' > /Users/tomwilliams/Projects/incard-rails/bin/spring:15:in `<top > (required)>' > bin/rails:3:in `load' > bin/rails:3:in `<main>' > Caused by: > ActiveModel::UnknownAttributeError: unknown attribute 'priority' for > CampaignOrder. > /Users/tomwilliams/Projects/incard-rails/db/migrate/20190326143614_insert_accepted_email_campaign.rb:66:in > > `up' > /Users/tomwilliams/Projects/incard-rails/bin/rails:9:in `require' > /Users/tomwilliams/Projects/incard-rails/bin/rails:9:in `<top (required)>' > /Users/tomwilliams/Projects/incard-rails/bin/spring:15:in `<top > (required)>' > bin/rails:3:in `load' > bin/rails:3:in `<main>' > Tasks: TOP => db:migrate > (See full trace by running task with --trace) Now, I can just *"fix"* it by running the migrate command again, or as I did, rollback the migrations and put the added column in the create table migration and deleting the add_column migration. My question is - does anybody know if this is a known issue, and if so, could someone provide a link. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
