    <p>In my application, I want to only allow user with admin privilege to access this model. So I set up and before_filter to check if the user is an Admin. The problem with this approach is that, after the admin user passes the filter, s/he won't be able to get redirect to the action. Instead, only the views are rendered, which leads to the <code>undefined method each' for nil:NilClass error</code>. What am I doing wrong here?</p> <pre><code>class TidbitsController &lt; ApplicationController before_filter :is_admin? layout "tidbits" # GET /tidbits # GET /tidbits.json protected def is_admin? unless current_user.admin? flash[:error] = "You are not authorized!" redirect_to "/" and return end end def index @tidbits = Tidbit.all respond_to do |format| format.html # index.html.erb format.json { render json: @tidbits } end end # GET /tidbits/1 # GET /tidbits/1.json def show @tidbit = Tidbit.find(params[:id]) respond_to do |format| format.html # show.html.erb format.json { render json: @tidbit } end end # GET /tidbits/new # GET /tidbits/new.json def new @tidbit = Tidbit.new respond_to do |format| format.html # new.html.erb format.json { render json: @tidbit } end end # GET /tidbits/1/edit def edit @tidbit = Tidbit.find(params[:id]) end # POST /tidbits # POST /tidbits.json def create @tidbit = Tidbit.new(params[:tidbit]) respond_to do |format| if @tidbit.save format.html { redirect_to @tidbit, notice: 'Tidbit was successfully created.' } format.json { render json: @tidbit, status: :created, location: @tidbit } else format.html { render action: "new" } format.json { render json: @tidbit.errors, status: :unprocessable_entity } end end end # PUT /tidbits/1 # PUT /tidbits/1.json def update @tidbit = Tidbit.find(params[:id]) respond_to do |format| if @tidbit.update_attributes(params[:tidbit]) format.html { redirect_to @tidbit, notice: 'Tidbit was successfully updated.' } format.json { head :no_content } else format.html { render action: "edit" } format.json { render json: @tidbit.errors, status: :unprocessable_entity } end end end # DELETE /tidbits/1 # DELETE /tidbits/1.json def destroy @tidbit = Tidbit.find(params[:id]) @tidbit.destroy respond_to do |format| format.html { redirect_to tidbits_url } format.json { head :no_content } end end end </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
