Usando "extension-object-storage". Set up object storage for an image gallery.
Resultado esperado:
- Backend: add the mops dependency and include the storage mixin in the main actor.
- Data model: store each image as ExternalBlob with filename and MIME type.
- Frontend: convert selected files to bytes, upload with progress, and render cached direct URLs.
Usando "extension-object-storage". Explain why every upload returns a 403 payload error.
Resultado esperado:
The backend package or storage mixin is probably missing. Verify both dependencies, remove custom reserved methods, rebuild, and redeploy the backend.
Usando "extension-object-storage". Review my document download approach.
Resultado esperado:
Use direct URLs for inline viewing. Fetch bytes for named downloads, preserve stored filenames, and revoke temporary browser URLs after use.

Puntuación de Skillstore
Por qué esta puntuación Confianza de la evidencia: MedioLo que puedes crear
Build a media gallery
Add image and video uploads, cached display, progress reporting, and persistent file metadata.
Deliver stored documents
Create inline previews and named downloads from ExternalBlob records without storing file bytes in canisters.
Repair failed uploads
Trace 403 responses to missing dependencies, absent mixins, incorrect data types, or invalid reserved method signatures.
Prueba estos prompts
Review my Caffeine AI project and list the required backend and frontend steps for object storage. Identify files that need changes.
Create an upload flow using ExternalBlob.fromBytes with filename, MIME type, and progress. Store the ExternalBlob reference in my Motoko record.
Implement inline media display with getDirectURL and named downloads with getBytes. Use stored MIME type or filename for file classification.
Audit my object storage integration for dependency, type, mixin, signature, and gateway errors. Explain each problem and propose precise corrections.
Mejores prácticas
- Store file references as Storage.ExternalBlob and retain filename plus MIME type as separate metadata.
- Install compatible backend and frontend packages together, then rebuild and redeploy after backend changes.
- Use direct URLs for inline media and byte downloads when the original filename must be preserved.
Evitar
- Do not store object references as text or implement reserved storage methods manually.
- Do not infer media types from opaque gateway URLs.
- Do not accept arbitrary uploads without application-level authorization, validation, size limits, and content controls.
