In config/initializers/database_options.rb I have the following: # use structure.sql, not schema.rb Rails.application.config.active_record.schema_format = :sql If I run the following: $ rake db:migrate it generates db/schema.rb , not db/structure.sql .

问题 I have upgraded a Rails 4 application to Rails 5 (5.2.4.1 to be exact). I have a GET endpoint in my code with an rspec test.

问题 Apologies for the question, I'm still learning rails. I'm trying to show in my html - all the users that a user has started following within the last month (i.e. recent users you've followed).

My second try was in my user model - but I get undefined method `call' for # Did you mean? caller following.html.erb <div

问题 I did bundle install and the mysql2 gem was updated from 0.4.10 to 0.5.0. After this anything involving ActiveRecord blows up with the error in the title. 回答1: ActiveRecord only works with specific versions of mysql2.
