When entering ActiveRecord statements in a Rails console, it can be useful to see what SQL queries are being executed under the hood.
> Book.first
Book Load (25.6ms) SELECT "books".* FROM "books" ORDER BY "books"."id" ASC LIMIT $1 [["LIMIT", 1]]
=> #<Book:0x00007f824ec6ff98
Notice the line right after the statement shows the corresponding select
query.
If you aren't seeing this line of SQL, then you'll need to turn on logging for ActiveRecord. For instance, your test environment may not be configured to log the SQL.
Right in your console, try running the following line:
> ActiveRecord::Base.logger = Logger.new(STDOUT)
Enter an ActiveRecord statement, you should now be seeing the corresponding SQL queries.
