But when i copy-paste your variant it's work.So difference is in formating code, i write in one line, you write in three lines.That's nice for resolving problem, but why it's works in divided style of ruby and not works in one-line style ?My one-line is <%= Chat.find_by(id: 6).chatusers.each { |chat_user| chat_user.user } %> which about i told.
The problem is that ruby is swallowing whatever happens inside the .each -- what you want is probably .map instead. The return value from .each is the collection. The return value from map is a new collection of the results of the block.
Try this:
Chat.find_by(id: 6).chatusers.map{|chat_user| chat_user.user}
