model:

class client < activerecord::base     has_many :visits     has_many :exchanges, through: :visits 

controller:

class clientscontroller < applicationcontroller     before_action :set_client, only: [:show, :edit, :update, :destroy]      def index         @clients = client.all     end       # /clients/new     def new         @client = client.new     end     # post /clients    # post /clients.json    def create         @client = client.new(client_params)          respond_to |format|           if @client.save               format.html { redirect_to @client, notice: 'client created.' }               format.json { render action: 'show', status: :created, location: @client }           else               format.html { render action: 'new' }               format.json { render json: @client.errors, status: :unprocessable_entity }           end        end    end    # patch/put /clients/1   # patch/put /clients/1.json   def update       respond_to |format|         if @client.update(client_params)             format.html { redirect_to @client, notice: 'client updated.' }             format.json { head :no_content }         else             format.html { render action: 'edit' }             format.json { render json: @client.errors, status: :unprocessable_entity }         end      end   end    # delete /clients/1   # delete /clients/1.json   def destroy       @client.destroy       respond_to |format|         format.html { redirect_to clients_url }         format.json { head :no_content }       end   end    private   # use callbacks share common setup or constraints between actions.   def set_client       @client = client.find(params[:id])   end    # never trust parameters scary internet, allow white list through.   def client_params       #hidden security   end end 

so error goes off @ line 1 client form when calls @client , says "undefined method `model_name' activerecord::relation::activerecord_relation_client:class" use have no idea going on, thanks.
