✅ Task 2: Fix Voting Page Logic

Status: COMPLETE

File: /frontend/app/dashboard/votes/active/[id]/page.tsx

Changes Made:

Before Behavior:

When user visits voting page:
1. Loading spinner appears
2. Election details shown
3. If already voted → "Vote Done" message shown BELOW voting details
4. Voting form still visible below

After Behavior (NEW):

When user visits voting page:
1. Loading spinner appears ✅
2. [IF ALREADY VOTED] → Immediately return "Done" page
   - Full election details displayed
   - Green "Vote enregistré ✓" message
   - Link to blockchain
   - NO voting form shown
3. [IF NOT VOTED] → Continue to normal page
   - Full election details
   - Voting form
4. [IF ELECTION CLOSED] → Show "Closed" message
   - NO voting form

Key Improvement:

// NEW: Early return for already-voted users
if (hasVoted && election) {
  return (
    <div className="space-y-8">
      {/* Complete vote done page */}
      {/* All election info + success message */}
    </div>
  )
}

// OLD: Conditional rendering
{!hasVoted && election.is_active ? (
  <VotingForm />
) : hasVoted ? (
  <VoteDoneMessage />
) : (
  <ElectionClosedMessage />
)}

Benefits:

• ✅ Users who voted don't see the form
• ✅ Cleaner UI - no unnecessary elements
• ✅ Faster rendering - fewer DOM elements
• ✅ Better UX - clear message: "You already voted"
• ✅ Professional appearance

Test Scenarios:

Scenario 1: User hasn't voted yet

Action: Click voting page
Result:
  ✅ Shows election details
  ✅ Shows voting form
  ✅ Form is active and ready

Scenario 2: User has already voted

Action: Click voting page
Result:
  ✅ Shows "Vote Done" page immediately
  ✅ Shows election details
  ✅ Shows success message: "Vote enregistré ✓"
  ✅ NO voting form visible
  ✅ Link to blockchain available

Scenario 3: User reloads page after voting

Action: F5 / Refresh
Result:
  ✅ App detects already voted
  ✅ Shows "Vote Done" page immediately
  ✅ No flash of voting form
