<%= f.select :group_name, options_for_select(@group_mst.collect{|x| [x.group_name]}), {:multiple => :multiple} %>

that is on the line 44.

And the error raised on that line says "The error occurred while evaluating nil.collect". The only thing receiving "collect" on that line is @group_mst, so the spec has to do something to assign an Enumerable to @group_mst before calling render in the spec. Is there a line in the controller that assigns something to @group_mst? If so, what's on that line?

 def new 
    @user_mst = UserMst.new 
    @group_mst = GroupMst.all 

    respond_to do |format| 
      format.html # new.html.erb 
      format.xml  { render :xml => @user_mst } 

  def edit 
    @user_mst = UserMst.find(params[:id]) 
        @group_mst = GroupMst.all 

 def create 
    @user_mst = UserMst.new(params[:user_mst]) 
        @group_mst = GroupMst.all 

    respond_to do |format| 
      if @user_mst.save 
        format.html { redirect_to(@user_mst, :notice => 'User mst was successfully created.') } 
        format.xml  { render :xml => @user_mst, :status => :created, :location => @user_mst } 
        format.html { render :action => "new" } 
        format.xml  { render :xml => @user_mst.errors, :status => :unprocessable_entity } 

Those are the lines I include @group_mst.
