问题 I have been building an app these days. The functionality is nothing fancy at all, I have to connect to a client's SOAP webservice, fetch some data, save it into my pg database and build a search functionality based on this data. The search has to be performed on two tables, both combined are like 80K rows. It needs to look for every word in the input text in several fields from these two tables, which have a classical assocation one to many. Previous to get my hands dirty I was looking at

问题 Rails 5.1 migrations generates BIGINT (instead of Integer ) for tables' primary keys (changelog). Is it possible to disable that somewhere in the config? If so, how to do disable it? 回答1: According to pull request, no this is not possible on config level. But you can, in fact, force id to be integer, like this: create_table :users, id: :integer do On the other hand, you must be aware that changes also affected references behavior, so you should be careful with those: t.references :orders,
