Question

I have a big issue with the select tag. In my view I have the following code:

 <%= select 'lw', Logicalwarehouse.all %>

In my controller:

....
@logical_wh = Logicalwarehouse.find(params['lw'])
    @project.logicalwarehouses << @logical_wh
    respond_to do |format|
      if @project.update_attributes(params[:project])
        flash[:notice] = 'Project was successfully updated.'
        format.html { redirect_to(@project) }
        format.xml  { head :ok }
      else
        format.html { render :action => "edit" }
        format.xml  { render :xml => @project.errors, :status => :unprocessable_entity }
      end
    end
...

Alternatively, I want use a drop.down menu in my view that will let me choose between all Logicalwarehouse objects that will return a chosen object inside the lw variable, back to controller. I am having an issue with the view select field. Rails returns an error that it has the wrong number of arguments (2 for 3), any suggestions?
Thank you all

Answer 1

I don’t know the name of an attribute that has description of your Logicalwarehouse. I assume it’s name:

<%= select "lw", "id", Logicalwarehouse.all.map{|lw| [ lw.name, lw.id ] } %>

UPD:
Selected id will be available through params[:lw][:id].
