Check the dash before applying the title in Rails

I'm really new to Ruby and Rails and should know how to check if a string contains a dash before applying titlelize.

@city = City.first :conditions => { :title => params[:city].titleize }

What do I need to do:

@city = City.first :conditions => { :title => params[:city] }

and then write something that will use titleize ONLY if the variable @city

does not contain a dash.

I love this solution, added by zachrose a couple of weeks ago: https://gist.github.com/varyonic/ccda540c417a6bd49aec



def nice_title(phrase)
  return phrase if phrase =~ /^-+$/
  phrase.split('-').map { |part|
    if part.chars.count == part.bytes.count
      part.titleize
    else
      part.split(' ').map { |word| word.mb_chars.titleize }.join(' ')
    end
  }.join('-')
end

if params[:city] =~ /-/
  @city = City.first :conditions => { :title => params[:city] }
else
  @city = City.first :conditions => { :title => params[:city].titleize }     
end


I don't know why you are using this, but I believe it will not work for all cases. There must be a better approach.
