How to Ship CRM Fixes Without a Rebuild
Apply low-risk CRM production fixes through configuration changes, targeted cache clears, rollback planning, and live verification.
How to ship CRM fixes without a rebuild
Goal
Fix production issues in a configurable CRM — a broken calculated field, a missing image, clipped output — using configuration changes plus a targeted cache clear, without a code redeploy or a full rebuild. Use this guide for low-risk production corrections where a rebuild would be slow, riskier, and out of proportion to the change.
Prerequisites
- [ ] Admin access to the CRM's entity/formula manager and its caching controls.
- [ ] The ability to reproduce the issue on a real record before and after the change.
- [ ] Knowledge of every caching layer in play (application cache, page cache, "used CSS" cache, CDN).
- [ ] A rollback plan — know the previous value of anything you change.
Steps
-
1
Confirm Config Fix
Confirm the fix is configuration, not code. If the change lives in a formula, a field setting, a content limit, or a stored asset, you can likely ship it without a rebuild. If it needs new logic, stop and use your normal release path.
-
2
Key on Changed Attribute
Fix a two-way calculated field by keying on the changed attribute. When a field must compute in both directions — enter a percentage and get the amount, or enter the amount and get the percentage — branch the formula on which attribute the user actually edited, so the field just touched drives the calculation and the linked totals stay correct:
-
3
Restore Missing Assets
Root-cause a "missing" asset before restoring it. A blank placeholder often isn't a code bug. An automated media cleaner can trash images it thinks are unused because they're referenced only inside a custom HTML widget it can't parse — the references are invisible to it. Restore the assets from the cleaner's trash rather than re-uploading blind.
-
4
Constrain Content
Constrain content to fit a fixed box. When text is clipped inside a fixed-height,
overflow:hiddenbox, don't enlarge the box — shrink the content to fit it. Lower the character limit feeding the renderer, match the input counter to the new limit so authors see the real ceiling, and reduce the font size and line height so the trimmed text sits cleanly. -
5
Save and Clear Caches
Save, then clear only the caches that matter. After each change, save and clear the specific caches involved — application/formula cache for a field, page and "used CSS" cache for a front-end asset. Clearing the right cache is what makes a config change go live; a rebuild is not required.
-
6
Verify Live
Verify live on a real record, both directions where relevant. Re-open the affected record in production and confirm the fix, including any inverse case (both directions of a two-way field, desktop and mobile for an asset).
result = isAttributeChanged(percent)
? base * percent / 100
: (amount / base) * 100
Configuration
| Change | Apply via | Cache to clear |
|---|---|---|
| Calculated / formula field | Entity/formula manager | Application/formula cache |
| Restored marketing image | Media library (restore from trash) | Page cache + used-CSS cache + CDN |
| Text clipped in a fixed box | Lower content limit + reduce font | Renderer/output cache |
Verification
- The calculated field returns correct results from either input, with no change to related totals.
- The restored asset returns HTTP 200 and renders on desktop and mobile.
- The clipped text now fits fully, verified on a worst-case long value.
- No rebuild or redeploy was needed, and the change is live.
Common problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Change made but nothing updates on screen | The relevant cache wasn't cleared | Clear the specific cache for that surface (app / page / used-CSS / CDN) |
| Two-way field breaks the other totals | Formula recomputes everything, not just the edited field | Branch on the changed attribute so only the touched field drives the calc |
| Image "missing" reappears then vanishes again | Automated cleaner keeps trashing it | It's referenced only in raw HTML; exempt it or restore and whitelist |
| Text still clips after limit change | Input counter still allows the old length | Match the author-facing counter to the new limit |
| Fix works locally, not in production | Front-end optimiser cache stale | Clear page and used-CSS caches for anonymous visitors |
Production checklist
- [ ] Confirmed the fix is config-only before choosing this path.
- [ ] Previous values recorded for rollback.
- [ ] Every relevant cache layer identified and cleared.
- [ ] Two-way fields verified from both inputs with no collateral change.
- [ ] Restored assets confirmed 200 on desktop and mobile.
- [ ] Clipped-content fixes verified against a worst-case value.
- [ ] Author-facing limits/counters aligned with renderer limits.
Related / Next steps
- Automated "unused asset" cleaners are blind to anything referenced in raw HTML, scripts, or custom widgets — keep an allowlist of assets used that way, or you'll fight the same disappearance repeatedly.
- When a fix genuinely needs new logic, don't force it through config: that's the case for your normal reviewed, staged release.
