Template rendering

TemplateNotFound: blog-post.html#

Delivery loads templates from S3 via the active template pack. Check:

1. Is the pack uploaded and marked as default for the site?
2. Does the manifest reference the template's slug?
3. Is the file path under templates/ and does it match the manifest's file: field?

"Variable X is undefined"#

In dev: enable Jinja StrictUndefined to make this loud (see the renderer config). In prod: a {{ var | default('') }} filter sweeps over expected- nullable fields.

"{{ content.fields.items }} shows <built-in method items of dict>"#

Python dicts have a method called items(). Use bracket notation:

1

{{ content.fields["items"] }}

This bites everyone once.

"Blocks render as nothing"#

Each block's type must match a key under block_types in the pack's manifest. Unknown types are silently skipped. Add the block type to the manifest (with fields: declaring its data shape) and re-upload the pack.
