Strip dash from params - Rails

How can I strip characters from params? If my params look like this:

<ActionController::Parameters {"utf8"=>"✓", "q"=><ActionController::Parameters {"search_fields_cont_any"=>"123-456", "category_eq"=>"", "created_at_gteq"=>"", "created_at_lteq"=>""} permitted: false>, "controller"=>"submissions", "action"=>"index", "page"=>nil, "per_page"=>nil} permitted: false>

params[:q][:search_fields_cont_any] => "123-456"

How can I modify the params so that it would look like this:

params[:q][:search_fields_cont_any] => "123456"

CONTROLLER

@q = Submission.submissions_for(user: current_user).ransack(filter_params(params[:q]))

Private method

def filter_params(params)
 params.require(:q).permit(:search_fields_cont_any)
end

Ideally I would modify the params in the private method. How can I do this?

How about:

def filter_params(params)
  params.require(:q).permit(:search_fields_cont_any)[:search_fields_cont_any].gsub!('-','')
end

In console:

params = ActionController::Parameters.new(q: {search_fields_cont_any: 'abc-def'})
 => {"q"=>{"search_fields_cont_any"=>"abc-def"}} 
params.require(:q).permit(:search_fields_cont_any)[:search_fields_cont_any].gsub!('-','')
 => "abcdef"

Or, as mudasobwa says (even better - saves you 1 character):

def filter_params(params)
  params.require(:q).permit(:search_fields_cont_any)[:search_fields_cont_any].delete!('-')
end

Again, in console: 

params = ActionController::Parameters.new(q: {search_fields_cont_any: 'abc-def'})
 => {"q"=>{"search_fields_cont_any"=>"abc-def"}} 
params.require(:q).permit(:search_fields_cont_any)[:search_fields_cont_any].delete!('-')
 => "abcdef"
