30-30: Consider grouping Django imports together.

The TruncDate import from django.db.models.functions should be grouped with other Django imports (lines 13-21) for better organization.

♻️ Suggested import organization

Move line 30 up to group with other Django imports:

 from django.db.models import Sum, Count, Q
+from django.db.models.functions import TruncDate
 from django.db import transaction
 from django.core.cache import cache
 from django.utils import timezone
 
 from apps.journal.models import Entry, FeaturedEntry
 from apps.journal.utils import (
     get_random_quote,
     get_user_local_date,
     get_today_date_range,
     parse_tags,
 )
-from django.db.models.functions import TruncDate
 from apps.api.serializers import (

233-245: Consider optimizing to avoid potential double query evaluation.

The queryset is evaluated twice: once for exists() (line 241) and once when iterating to build the dates list (line 245). You could simplify this by fetching the list directly and checking its length.

♻️ Suggested optimization

         # Get all days with entries (with word_count > 0)
-        entry_dates = (
+        dates = list(
             Entry.objects.filter(user=user, word_count__gt=0)
             .annotate(day=TruncDate('created_at', tzinfo=user_tz))
-            .values('day')
-            .distinct()
+            .values_list('day', flat=True)
             .order_by('day')
+            .distinct()
         )
         
-        if not entry_dates.exists():
+        if not dates:
             return 0
-        
-        # Get unique dates as a list
-        dates = sorted(set(item['day'] for item in entry_dates))

18-21: Add @pytest.mark.streak domain marker per coding guidelines.

The coding guidelines specify using domain markers for tests. Since these tests cover streak functionality, add the @pytest.mark.streak marker.

♻️ Suggested fix

 `@pytest.mark.integration`
+@pytest.mark.streak
 `@pytest.mark.django_db`
 class TestDashboardStreakRealTime:
     """Tests for real-time streak calculation in dashboard."""

As per coding guidelines: "Use pytest with markers (@pytest.mark.unit, @pytest.mark.integration, @pytest.mark.slow) and domain markers (@pytest.mark.encryption, @pytest.mark.streak, @pytest.mark.statistics)"
