    respond_to do |format|

      if @state.save

        format.html { redirect_to @state, notice: 'State was successfully created.' }

        format.json { render json: @state, status: :created, location: @state }

      else

        format.html { render action: "new" }

        format.json { render json: @state.errors, status: :unprocessable_entity }

      end

    end

  end

 

  def countries_state 

@state = State.find("country_id = :c_id",{:c_id => params[:country]})

respond_to do |format|

format.html

format.js

end

  end

  

  # PUT /states/1

  # PUT /states/1.json

  def update

    @state = State.find(params[:id])

    respond_to do |format|

      if @state.update_attributes(params[:state])

        format.html { redirect_to @state, notice: 'State was successfully updated.' }

        format.json { head :ok }

      else

        format.html { render action: "edit" }

        format.json { render json: @state.errors, status: :unprocessable_entity }

      end

    end

  end

  # DELETE /states/1

  # DELETE /states/1.json

  def destroy

    @state = State.find(params[:id])

    @state.destroy

    respond_to do |format|

      format.html { redirect_to states_url }

      format.json { head :ok }

Hey AJ

Yes, to serve any request made by your client, you would need something on the server to handle the request.
As for rendering the dropdown, this is a pretty simple thing to do with jQuery. Look around, you should find something quite easily.

Hey AJ

In your ajax call, you need to pass the id of the selected state if you are using a nested resource url structure.
Your js would looks something like this:

$(document).ready(function() {
    var country_states_path = '/countries/:id/states;
    $("#client_country_id").change(function() {
        var state_id = $(this).val();
        $.ajax({
            type: "GET",
            url: country_states_path.replace(":id", id),
            success: function(data) {
                // Code to populate cities
            }
        });
    });
});

Incase you are not using nested resources, you still need to pass the state_id that was selected currently. Using the below js, in your controller, the state id would be available as params[:state]

$(document).ready(function() {
    var country_states_path = '/states/';
    $("#client_country_id").change(function() {
        var country_id = $(this).val();
        $.ajax({
            type: "GET",
            data: {country: country_id},
            url: country_states_path,
            success: function(data) {
                // Code to populate cities
            }
        });
    });
});
