Daniel Colson bfee5d8dcc Set up reloading after_initialize ... Alternate fix for #336. We went with #347 instead because the solution in this commit didn't work with Rails 4.2. Since we are no longer supporting Rails 4.2, I think this is a better approach. The original problem looked like this: Rails runs all of the initializers 1. Run the ["factory_bot.set_factory_paths"][set_factory_paths] initializer 2. Run the ["factory_bot.register_reloader"][register_reloader] initializer, which sets up a [prepare callback][] 3. Run the [`:run_prepare_callbacks`][] initializer 4. This triggers the factory_bot [prepare callback][], which causes factory\_bot to [reload][] Rails runs `after_initialize` callbacks 1. [I18n initializes] 2. factory\_bot [reloads again][] as described in #334 Triggering the first factory_bot reload before initializing I18n could cause an error in some cases. We avoided the problem in #347 by adding a conditional to skip reloading factory_bot before the application has initialized. This commit, on the other hand, moves factory_bot reloading from a prepare callback into an `after_initialize` callback. The initialization process is now simplified to: Rails runs all of the initializers 1. Run the ["factory_bot.set_factory_paths"][set_factory_paths] 2. Run the [`:run_prepare_callbacks`][] initializer, which no longer involves factory_bot Rails runs `after_intialize` callbacks 1. [I18n initializes] 2. factory_bot loads definitions for the first time. It then runs the reloader to set up the prepare callback to reload factory_bot when the application reloads (for example by calling `reload!` in the console), and to register the reloader to trigger reloads when any factory_bot definition files change.
