i got some errors on my ruby on rails project, when i tried to get strings from two different hashes.
it catched all the data, but it added always !map:HashWithIndifferentAccess
in front of my data.
i solved that by doing a little trick.
comment.title = params[:title]
and changed it so use only the data from the hash i want to use
comment.title = params[:title][:thefieldiwanttouse].to_s
