Planner Module (Backend) — Code-Sourced Overview (Dec 2025)

Scope: backend/igny8_core/modules/planner (ViewSets/serializers/urls) and backing models in backend/igny8_core/business/planning.

Endpoints (routed from modules/planner/urls.py)

• /api/v1/planner/keywords/ — CRUD + bulk actions, CSV import/export, clustering trigger.
• /api/v1/planner/clusters/ — CRUD with aggregated stats (keywords/volume/difficulty/ideas/content).
• /api/v1/planner/ideas/ — CRUD for content ideas tied to clusters/keywords.

Models (business/planning/models.py)

• Clusters (SiteSectorBaseModel, soft-delete): name, description, keywords_count, volume, mapped_pages, status(new|mapped), disabled; unique per site, sector. Indexes on name, status, site, sector.
• Keywords (SiteSectorBaseModel, soft-delete): FK seed_keyword (global), overrides volume_override, difficulty_override, attribute_values; FK cluster (same sector); status(new|mapped), disabled. Unique per seed_keyword, site, sector. Properties expose keyword, volume, difficulty, intent from seed keyword. Save enforces industry/sector alignment between site/sector and seed keyword.
• ContentIdeas (SiteSectorBaseModel, soft-delete): idea_title, description, target_keywords (legacy), M2M keyword_objects, FK keyword_cluster (same sector), status(new|queued|completed), disabled, estimated_word_count, content_type (post/page/product/taxonomy), content_structure (article/guide/etc.). Tracks metadata (audience, tone, outlines, brief), CTA fields, review flags (is_priority, is_assigned, is_review_required), language, published URL, audit fields. Indexes on site, sector, keyword_cluster, status, idea_title.

Serializers

• KeywordSerializer: read-only keyword metrics from seed keyword; requires seed_keyword_id on create; optional on update; validates site/sector via the ViewSet; surfaces cluster_name, sector_name, volume/difficulty/intent.
• ClusterSerializer (cluster_serializers.py): computes keywords_count, volume, difficulty, ideas_count, content_count; bulk prefetch helper to avoid N+1. Annotated volume/difficulty via overrides or seed keyword values.
• ContentIdeasSerializer: links to clusters and keywords; exposes cluster/sector names; supports site/sector write-only ids; legacy taxonomy getter retained for backward compatibility.

ViewSets (modules/planner/views.py)

• KeywordViewSet (SiteSectorModelViewSet):
  • Filtering/search/order: search by seed keyword text; filter by status, cluster, intent, seed_keyword_id; ordering by created_at, volume, difficulty.
  • Custom filters: difficulty_min/max, volume_min/max using override-first logic.
  • Bulk actions: bulk_delete, bulk_update (status), bulk_add_from_seed (validates industry/sector alignment, requires site/sector), import_keywords CSV (site/sector required, creates Keywords), export CSV (ids filter supported).
  • Clustering: auto_cluster calls ClusteringService.cluster_keywords; enforces min keyword count (5) and credits; returns async task_id or sync result.
  • Create requires site_id and sector_id (validated against site/sector and account).
• ClusterViewSet:
  • Filters/search/order: search by name; filter by status; ordering on name/created_at/keywords_count/volume/difficulty.
  • Annotates volume/difficulty using overrides; uses serializer prefetch to reduce N+1.
  • Export endpoints not present; CRUD via standard actions.
• ContentIdeasViewSet:
  • CRUD for ideas; filters on status/cluster; search by title/description/keywords; ordering by created_at/status.
  • Generates title/brief via IdeasService.generate_content_idea; enforces credits (catches InsufficientCreditsError).
  • Bulk assign status not present; focused on single-item generation and listing.

Services (business/planning/services)

• ClusteringService: clusters keywords; invoked by auto_cluster; credit-aware.
• IdeasService: generates content ideas (title/brief) from keywords; used in ContentIdeasViewSet.

Permissions, tenancy, and throttling

• Permissions: IsAuthenticatedAndActive + IsViewerOrAbove for all planner endpoints.
• Tenancy: SiteSectorModelViewSet base ensures account/site/sector scoping; create/import/add-from-seed require explicit site_id + sector_id with consistency checks.
• Throttling: DebugScopedRateThrottle with scope planner.

CSV Import/Export

• Export: /planner/keywords/export supports ids filter; outputs CSV with keyword, volume, difficulty, intent, status, cluster.
• Import: /planner/keywords/import_keywords expects CSV with keyword, volume, difficulty, intent, status; site_id and sector_id required in query params; skips duplicates per site/sector/account.

Notes / gaps

• Two bulk_update methods exist in KeywordViewSet (duplicate definitions); consolidate to one.
• No dedicated bulk idea status update; consider parity with keywords.
• Legacy taxonomy references removed; ContentIdeas retains a legacy getter for taxonomy name but model FK is removed.
