You are helping me fix my FastAPI-based manager dashboard in this Replit project. Goal: - Make the dashboard tiles and contact table show real data from Supabase views we’ve already created. Supabase views that EXIST and must be used: 1) v_conversation_stats_monthly Columns: - month_uk (date) - new_contacts - responses_48h - inbound_late - followups_created - out_sent - in_recv - total_msgs - generated_at_uk 2) v_campaign_performance_monthly Columns (at least): - month_uk (date) - campaign_tag - outreached - replies (may be null) - attended - reply_rate_pct (may be null) - attended_rate_pct - generated_at_uk 3) v_retention_pen_monthly Columns: - month_uk (date) - dealt_count - purchased_elsewhere_count - total_measured - retention_pen_pct (may be null) 4) v_manager_monthly_contacts Columns: - month_start_uk (date) - agreement_id - agreement_number - customer_name - out_count_month - in_count_month - last_at_month - last_dir_month - last_msg_preview_month - has_dealt_month - has_appt_month - last_reason_category - last_reason_label - contact_status -- values like: 'appointment', 'no_response', 'declined', 'engaged' - status_colour -- values like: 'yellow', 'grey', 'red', 'blue' There are also three T-card views, which already work and must NOT be changed: - v_tcard_summary - v_tcard_appointments - v_tcard_contact_history What I need you to do: 1) Open `dashboard_app.py`. 2) Fix the `/api/kpis` endpoint so that: - It takes an optional query parameter `month` (string: 'YYYY-MM-01'). - If `month` is not provided, it should automatically use the MOST RECENT `month_uk` from `v_conversation_stats_monthly`. - It should query: - `v_conversation_stats_monthly` filtered by `month_uk = month` - `v_campaign_performance_monthly` filtered by `month_uk = month` - `v_retention_pen_monthly` filtered by `month_uk = month` - It should then return JSON in this EXACT shape: { "month": "", "active_conversations": , // use new_contacts "campaigns_sent": , // sum of 'outreached' across all campaigns for that month "reply_rate": , // replies_48h / NULLIF(new_contacts,0) * 100, default 0 if no contacts "retention_rate": // retention_pen_pct from v_retention_pen_monthly (default 0 if null) } Implementation details: - Use the existing Supabase client in this file. - For v_conversation_stats_monthly, pick single row with eq("month_uk", month).single(). - For v_campaign_performance_monthly, sum outreached over all rows for the month. - For v_retention_pen_monthly, if there is no row for that month, treat retention_rate as 0. - Ensure all values are numeric (int or float) so the frontend can display them. 3) Fix the `/api/contacts` endpoint so that: - It also takes an optional `month` query parameter ('YYYY-MM-01'). - If `month` is not provided, it should use the same logic as `/api/kpis` to choose the latest `month_uk`. - It must query `v_manager_monthly_contacts` with `eq("month_start_uk", month)` and order by `customer_name` ascending. - It should return JSON in this EXACT shape: { "month": "", "contacts": [ { "agreement_id": ..., "agreement_number": "...", "customer_name": "...", "out_count_month": ..., "in_count_month": ..., "last_at_month": "...", "last_dir_month": "...", "last_msg_preview_month": "...", "has_dealt_month": true/false, "has_appt_month": true/false, "last_reason_category": "...", "last_reason_label": "...", "contact_status": "...", "status_colour": "yellow/red/blue/grey" }, ... ] } - Make sure the endpoint returns an empty list `[]` for contacts if there are no rows, not null. 4) Open `templates/index.html` and update ONLY the JavaScript section that fetches KPIs and contacts, so that: - On page load (and when the Reload button is clicked): * Reads the currently selected month from the dropdown (in format 'November 2025'). * Converts it to first-of-month string '2025-11-01' for the API (you can map month names to 1–12). * Calls: GET `/api/kpis?month=YYYY-MM-01` GET `/api/contacts?month=YYYY-MM-01` - When the `/api/kpis` response returns: * Set the text content of the tiles to: - Active Conversations → kpis.active_conversations - Campaigns Sent → kpis.campaigns_sent - Reply Rate → kpis.reply_rate + '%' - Retention Rate → kpis.retention_rate + '%' - When the `/api/contacts` response returns: * Clear the existing table body. * For each contact in `contacts`: - Render a row with: Status dot colour based on `status_colour` Customer name Last contact time (use last_at_month, formatted to a readable date/time or '—' if null) Activity preview (use last_msg_preview_month or 'No activity yet') - Make the entire row clickable. - On click, call the existing T-card endpoint (which you already wired) for that `agreement_number` and open the T-card drawer. - If either API call fails, log the error to console and keep the UI stable (just don’t crash). 5) Run the FastAPI app (the existing Dashboard workflow) and manually test inside the Replit shell: - Use `curl` or `http` to call: - `GET http://0.0.0.0:5000/api/kpis` - `GET http://0.0.0.0:5000/api/contacts` and confirm they return valid JSON with NON-zero values using the data currently in the database (for November 2025 we know there are 3 contacts and non-zero message counts). 6) Once the APIs return correct JSON, verify from the web UI that: - The 4 tiles show non-zero values (Active Conversations, Campaigns Sent, Reply Rate, Retention Rate). - The contact table lists at least Jonathan, David and Caroline. - Clicking a row opens the T-card with detailed information. Please make all of these changes and then summarise exactly what you changed (files and key functions) along with a sample of the JSON returned by `/api/kpis` and `/api/contacts` after the fix.
