After freezing edge rails, all my controller examples are failing with MissingTemplate errors. e.g., ‘Missing template attachments/create.erb in view path app/views’
Trying to actually render the views gives me the same error.
I noticed I can fix most of them by using respond_to but I usually never use it. I almost always only need to respond to one format in one action so I omit respond_to and let Rails figure out which file to render.
Does Rails suddenly require respond_to blocks in every action as of 2.3?
Just found this, which answers my question:
