xml - Way to return True/False with rails api? -

i need create method, gets called local application 2 parameters. how can return true or false then? xml? method looks this:

def check_license   app_id = params[:id]   app_sn = params[:sn]    @license = license.find_by_id(app_id)    respond_to |format|     if @license.app_serial == app_sn       # should return true here    else      # should return false here    end   end end 

thanks in advance!

you first need decide format other internal application call application. popular (and sane) formats xml or json.

then, in controller, need render response in each of formats:

resp = @license.app_serial == app_sn respond_to |format|    format.json { render :json => resp }    format.xml       if resp         head :ok       else         render :xml => resp, :status => 403 # that's failed authentication response       end    end end
