Code Review
This pull request fixes a variable assignment error in the character creation page and introduces a new character editing page. The new page allows users to fetch and update character details, including tags and images, using PocketBase. Several improvements were identified: the initial data fetch lacks error handling, redundant operations are performed on a new FormData object, and appending the owner ID during an update could lead to unintended ownership changes. Additionally, the UI should use a form element for better accessibility, and a typo in a name attribute needs to be corrected.

Missing required-field validation before submit.
Unlike createCharacter (which validates newCharName/newCharDescription/newCharOrigin are non-empty), updateCharacter submits directly. A user who clears the Name or Description field and clicks Update will either get a server-side validation error or successfully persist empty required values, depending on the PocketBase schema. Mirror the create-form validation here for consistent UX.

const updateCharacter = async () => {
const formData = new FormData();
charErrorText = '';

PocketBase 0.26.8 update multi-value field empty array relations
💡 Result:
No specific changes or fixes related to multi-value (multiple relation) fields and empty array relations were made in PocketBase v0.26.x series, including any potential v0.26.8 release. The v0.26.x releases (v0.26.0 through v0.26.6 confirmed) focus on dependency updates, minor bug fixes like error serialization and OIDC support, AWS SDK replacement, and timeout adjustments, but nothing mentions relation fields or empty arrays. Multi-value relation fields in PocketBase are stored as JSON arrays of record IDs. Empty relations are represented as empty arrays []. Known past issues with multi-relations (e.g., API rules :length operator not recognizing empty strings as empty arrays, fixed in v0.16.10; multipart form binding fixed in v0.16.6) predate v0.26.x. Official docs confirm standard handling: set to [] for empty, use field+/field- modifiers for append/remove. No evidence of bugs or changes in v0.26.8 specifically addressing "empty array relations". If experiencing issues, check field defaults (toggle single/multiple to normalize), API rules, or client-side sending (e.g., empty array vs empty string).

PocketBase FormData update field clearing convention unset
💡 Result:
In PocketBase, record updates via the API (PATCH /api/collections/{collection}/records/{id}) are partial updates: only fields explicitly included in the request body are processed and potentially changed. Fields omitted from the FormData or JSON body retain their existing database values unchanged. To intentionally clear or unset a field during an update (set it to null/empty/zero-value), explicitly include it in the request body with the desired clearing value: - For most scalar fields (text, number, etc.): use empty string "" or null (if the field supports null and is not required). - For file fields: use empty string "" or [] (empty array) when using FormData to clear all files. Examples from official docs: formData.append('documents', '') or { 'documents': [] }. - For JSON fields: send null, empty object {}, or empty array [] as appropriate. - For relations and arrays: use [] for empty, or field- modifier (e.g., 'tags-': ['id1']) to remove specific items. This behavior is confirmed in the RecordUpsert form source code, where only submitted fields (via Load(data)) call record.SetIfFieldExists(k, v), leaving omitted fields untouched. Official file handling docs explicitly state setting file fields to empty string/[] in FormData clears them. JS SDK examples and API reference show update(body) processes only provided fields. Example clearing a text field with FormData: const formData = new FormData; formData.append('title', ''); // clears title formData.append('otherField', 'keep this'); await pb.collection('example').update('RECORD_ID', formData); Omitting 'title' entirely would leave it unchanged.

formData.delete(...) calls are no-ops on a freshly constructed FormData.
formData is created on line 34 and nothing is appended to images or tag_names before the delete() calls on lines 38 and 47. Both deletions do nothing. PocketBase performs partial updates—only fields explicitly included in the request are processed; omitted fields retain their existing values.
Current behavior:
- Uploading no new pictures leaves existing
imagesuntouched (likely intentional, but thedeleteis dead code). - Removing all tags (
charTags = []) will NOT clear them on the server becausetag_namesis never appended to FormData when the array is empty, leaving existing tags unchanged.
The tag_names field (JSON type) must always be sent to replace its value on the server. When charTags is empty, explicitly append an empty value to FormData to clear the field:

There was a problem hiding this comment.
Overwriting owner on every update is risky.
This unconditionally sets owner to the currently authenticated user's id. If a user with edit permission (e.g. an admin or a future shared-edit feature) updates a character they don't own, this silently transfers ownership. Even for the common case where the editor is the owner, sending owner on update is unnecessary and expands the attack surface (a misconfigured update rule on the server could let a non-owner take ownership).
Consider simply not sending owner on update — it should be immutable after creation, enforced by PocketBase collection rules.
