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

Question

i am learning rails and creating a web app which also got ecommerce in it
There is a Form which user can fill only if he is logged in, For that i was using Devise, then for e-commerce i installed Spree
Spree got its own login authentication, and there is no authenticate_user! in controllers too,
i removed devise and having a tough time finding how to use Spree's authentication with my Form
here is 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]
# GET /complaints
# GET /complaints.json
def require_login
redirect_to spree_login_path unless current_spree_user
end
def index
#complaints = Complaint.all
end
# GET /complaints/1
# GET /complaints/1.json
def show
end
# GET /complaints/new
def new
#complaint = Complaint.new
end
# GET /complaints/1/edit
def edit
end
# POST /complaints
# POST /complaints.json
def create
#complaint = Complaint.new(complaint_params)
respond_to do |format|
if #complaint.save
format.html { redirect_to #complaint, notice: 'Complaint was successfully 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 do |format|
if #complaint.update(complaint_params)
format.html { redirect_to #complaint, notice: 'Complaint was successfully 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 do |format|
format.html { redirect_to complaints_url, notice: 'Complaint was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_complaint
#complaint = Complaint.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the 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 do |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 you sure?' } %></td>
</tr>
<% end %>
</tbody>
</table>
<br>
<%= link_to 'New Complaint', new_complaint_path %>
<% else %>
<h1> please login</h1>
<% end %>
This works, as it verifies user's authentication in View, is there any way to check it in controller? Like if user is logged in it will be sent to action or else redirected to login?
Thank you

Spree uses devise authentication through a extension:
https://github.com/spree/spree_auth_devise
For authenticate your actions at controller(your own controllers) level, you need to define your own authentication filter. So you can manage something like this:
before_action :require_login
def require_login
redirect_to login_url unless current_spree_user
end
