> I'll help you set up the Laravel application with the required functionality. Here's the implementation: ```xml 'datetime', 'last_login_at' => 'datetime', ]; public function client() { return $this->belongsTo(Client::class); } public function isAdmin() { return $this->role === self::ROLE_ADMIN; } public function isManager() { return $this->role === self::ROLE_MANager; } public function isAuditor() { return $this->role === self::ROLE_AUDITOR; } public function isVoter() { return $this->role === self::ROLE_VOTER; } } 'datetime', 'end_date' => 'datetime', 'voting_start_time' => 'datetime', 'voting_end_time' => 'datetime', ]; public function users() { return $this->hasMany(User::class); } public categories() { return $this->hasMany(Category::class); } public function candidates() { return $this->hasMany(Candidate::class); } public function votes() { return $this->hasMany(Vote::class); } } belongsTo(Client::class); } public function candidates() { return $this->hasMany(Candidate::class); } } belongsTo(Client::class); } public function category() { return $this->belongsTo(Category::class); } public function votes() { return $this->hasMany(Vote::class); } } 'datetime', ]; public function client() { return $this->belongsTo(Client::class); } public function voter() { return $this->belongsTo(User::class, 'voter_id'); } public function candidate() { return $this->belongsTo(Candidate::class); } public function category() { return $this->belongsTo(Category::class); } } id(); $table->string('name'); $table->text('description')->nullable(); $table->dateTime('start_date'); $table->dateTime('end_date'); $table->time('voting_start_time'); $table->time('voting_end_time'); $table->string('timezone'); $table->string('status')->default('pending'); $table->timestamps(); }); } public function down() { Schema::dropIfExists('clients'); } }; id(); $table->foreignId('client_id')->constrained(); $table->string('name'); $table->text('description')->nullable(); $table->integer('max_selections')->default(1); $table->timestamps(); }); } public function down() { Schema::dropIfExists('categories'); } }; id(); $table->foreignId('client_id')->constrained(); $table->foreignId('category_id')->constrained(); $table->string('name'); $table->text('description')->nullable(); $table->string('photo_url')->nullable(); $table->timestamps(); }); } public function down() { Schema::dropIfExists('candidates'); } }; id(); $table->foreignId('client_id')->constrained(); $table->foreignId('voter_id')->constrained('users'); $table->foreignId('candidate_id')->constrained(); $table->foreignId('category_id')->constrained(); $table->timestamp('voted_at'); $table->timestamps(); }); } public function down() { Schema::dropIfExists('votes'); } }; all(), [ 'name' => 'required|string|max:255', 'description' => 'nullable|string', 'start_date' => 'required|date', 'end_date' => 'required|date|after:start_date', 'voting_start_time' => 'required|date_format:H:i', 'voting_end_time' => 'required|date_format:H:i|after:voting_start_time', 'timezone' => 'required|timezone', ]); if ($validator->fails()) { return redirect()->back() ->withErrors($validator) ->withInput(); } Client::create($request->all()); return redirect()->route('clients.index') ->with('success', 'Client created successfully.'); } public function show(Client $client) { return view('clients.show', compact('client')); } public function edit(Client $client) { return view('clients.edit', compact('client')); } public function update(Request $request, Client $client) { $validator = Validator::make($request->all(), [ 'name' => 'required|string|max:255', 'description' => 'nullable|string', 'start_date' => 'required|date', 'end_date' => 'required|date|after:start_date', 'voting_start_time' => 'required|date_format:H:i', 'voting_end_time' => 'required|date_format:H:i|after:voting_start_time', 'timezone' => 'required|timezone', ]); if ($validator->fails()) { return redirect()->back() ->withErrors($validator) ->withInput(); } $client->update($request->all()); return redirect()->route('clients.index') ->with('success', 'Client updated successfully.'); } public function destroy(Client $client) { $client->delete(); return redirect()->route('clients.index') ->with('success', 'Client deleted successfully.'); } } categories()->with('candidates')->get(); return view('votes.index', compact('client', 'categories')); } public function store(Request $request, Client $client) { $user = Auth::user(); if ($user->client_id !== $client->id) { abort(403, 'Unauthorized action.'); } if ($client->status !== 'active') { return redirect()->back() ->with('error', 'Voting is not active for this client.'); } $now = now(); $start = $client->voting_start_time; $end = $client->voting_end_time; if (!$now->between($start, $end)) { return redirect()->back() ->with('error', 'Voting is only allowed between ' . $start .

Database models for: - Users with different roles (admin, manager, auditor, voter) - Clients (voting sessions) - Categories (for candidates) - Candidates - Votes 2. Controllers for: - Managing clients (voting sessions) - Handling the voting process 3. Key features: - Time-based voting windows - Role-based access control - Vote validation - Multiple candidate selection per category - Email notifications To complete the setup, you'll need to: 1. Install Laravel Breeze for authentication 2. Create the corresponding views 3. Set up email configuration 4. Implement the email notifications 5. Create the audit logging functionality Would you like me to provide any of these additional components?
