ruby on rails - How to use Spree's Authentication in form -

i learning rails , creating web app got ecommerce in there form user can fill if logged in, using devise, e-commerce installed spree spree got own login authentication, , there no authenticate_user! in controllers too, removed devise , having tough time finding how use spree's authentication form

here updated form's controller: complaints_controller.rb

module spree class complaintscontroller < spree::storecontroller   before_action :require_login    before_action :set_complaint, only: [:show, :edit, :update, :destroy]    # /complaints   # /complaints.json     def require_login       redirect_to spree_login_path unless current_spree_user     end          def index         @complaints = complaint.all       end    # /complaints/1   # /complaints/1.json   def show   end    # /complaints/new   def new     @complaint = complaint.new   end    # /complaints/1/edit   def edit   end    # post /complaints   # post /complaints.json   def create     @complaint = complaint.new(complaint_params)      respond_to |format|       if @complaint.save         format.html { redirect_to @complaint, notice: 'complaint created.' }         format.json { render :show, status: :created, location: @complaint }       else         format.html { render :new }         format.json { render json: @complaint.errors, status: :unprocessable_entity }       end     end   end    # patch/put /complaints/1   # patch/put /complaints/1.json   def update     respond_to |format|       if @complaint.update(complaint_params)         format.html { redirect_to @complaint, notice: 'complaint updated.' }         format.json { render :show, status: :ok, location: @complaint }       else         format.html { render :edit }         format.json { render json: @complaint.errors, status: :unprocessable_entity }       end     end   end    # delete /complaints/1   # delete /complaints/1.json   def destroy     @complaint.destroy     respond_to |format|       format.html { redirect_to complaints_url, notice: 'complaint destroyed.' }       format.json { head :no_content }     end   end    private     # use callbacks share common setup or constraints between actions.     def set_complaint       @complaint = complaint.find(params[:id])     end      # never trust parameters scary internet, allow white list through.     def complaint_params       params.require(:complaint).permit(:id_society, :id_user, :heading, :text, :active, :action, :isdelete, :flat_number)     end end end <% end %> 

index.html.erb

  <% if spree_current_user %>   <p id="notice"><%= notice %></p>  <h1>listing complaints</h1>  <table>   <thead>     <tr>       <th>id society</th>       <th>id user</th>       <th>heading</th>       <th>text</th>       <th>active</th>       <th>action</th>       <th>isdelete</th>       <th>flat number</th>       <th colspan="3"></th>     </tr>   </thead>    <tbody>     <% @complaints.each |complaint| %>       <tr>         <td><%= complaint.id_society %></td>         <td><%= complaint.id_user %></td>         <td><%= complaint.heading %></td>         <td><%= complaint.text %></td>         <td><%= complaint.active %></td>         <td><%= complaint.action %></td>         <td><%= complaint.isdelete %></td>         <td><%= complaint.flat_number %></td>         <td><%= link_to 'show', complaint %></td>         <td><%= link_to 'edit', edit_complaint_path(complaint) %></td>         <td><%= link_to 'destroy', complaint, method: :delete, data: { confirm: 'are sure?' } %></td>       </tr>     <% end %>   </tbody> </table>  <br>  <%= link_to 'new complaint', new_complaint_path %>  <% else %> <h1> please login</h1> <% end %> 

this works, verifies user's authentication in view, there way check in controller? if user logged in sent action or else redirected login?

thank you

spree uses devise authentication through extension:

https://github.com/spree/spree_auth_devise   

for authenticate actions @ controller(your own controllers) level, need define own authentication filter. can manage this:

before_action :require_login  def require_login   redirect_to login_url unless current_spree_user end
