Field groups and location rules

[SirLouen]

Closes #101

Draft while the cycle runs. S1 and S2 are in, S3 to S5 follow on this branch, so this is not ready for review yet.

What is in so far

• The location rule engine: OR groups of AND rows over {source, operator, value}, the param registry seam for future sources, and the built-in content type param with its any value.
• Field groups in the schema, with fields moving out of a per type column into a group and flattening back onto every type whose rules a group matches.
• Migration 00013 carrying existing fields into one default group per fielded type, with a Down that reverses it.
• The freeze: a group that stops matching leaves its stored values alone instead of making the item uneditable.

What is still to come

• S3 the groups REST surface, including the field move and the cross group key collision refusal.
• S4 the field groups screen, superseding the per type fields dialog.
• S5 the retirement sweep of the old per type field routes and dialog.

Why it is safe to sit here mid cycle

Every existing endpoint behaves exactly as before, because the per type field verbs resolve their group behind the scenes. The public handshake is byte identical, pinned by a golden fixture captured from the pre migration code and asserted again after the migration runs.

Testing

1. Run make db-up, then go test ./internal/... ./cmd/... ./test/... All green.
2. Run make cover. 100% with no uncovered blocks.
3. The migration proof is TestMigrationCarriesFieldsIntoDefaultGroups, which rolls back to 00012, seeds the old per type shape, migrates, and reads the result back through the new store.

📝 Walkthrough

Walkthrough

The change moves field ownership from content types to field groups. Groups use location rules to select content types. PostgreSQL, APIs, frontend administration, migrations, translations, and tests now support group-scoped field management.

Changes

Field groups and rules

Layer / File(s)	Summary
Domain model and rule engine internal/content/*	Adds field groups, location rules, parameter registration, matching, validation, normalization, collision checks, and grouped-field operations.
PostgreSQL storage and migration internal/postgres/*	Adds the field_groups table, migrates fields to group_id, updates queries and relation handling, flattens matching group fields onto content types, and preserves values during field moves.
HTTP API and integration behavior internal/server/*, test/features/*	Replaces type-scoped field routes with group and grouped-field routes. Adds handlers, error mappings, in-memory stores, and end-to-end scenarios.
Frontend administration frontend/src/content/*, frontend/src/router.tsx, frontend/src/menu/*	Adds the Field Groups screen, rule editor, group-scoped field dialog, field movement, API clients, navigation, and route protection.
Validation, localization, and documentation frontend/src/test/*, internal/*_test.go, languages/*, docs/*	Adds unit, API, PostgreSQL, server, frontend, feature, translation, and documentation updates for field groups and location rules.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to f3342

Concurrent group deletion and field movement can erase current content and revision values even when the field remains available through another group, creating a high-impact data-loss risk. This PR is not merge-ready until deletion is serialized with ownership changes and cleanup ownership is revalidated.

238-262: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Guard the relation target when no content type is loaded.

targets comes from props.types. GroupsScreen passes types.data ?? [], and it renders the rows as soon as the groups query settles, so the types query can still be pending or failed. In that case targets is empty and target is undefined. If the operator then picks the relation kind, SelectControl receives value={undefined} and line 261 reads target.value, which throws.

Disable the relation kind, or fall back to a safe value, when targets is empty.

🛡️ Proposed guard

 	const relating = kind.value === 'relation'
 	const add = useMutation({
 		mutationFn: () =>
 			createFieldInGroup(props.group, {
 				key: slugifyKey(label),
 				label,
 				kind: kind.value,
-				relatesTo: relating ? target.value : undefined,
+				relatesTo: relating ? target?.value : undefined,
 				many: relating && holding.value === 'many',
 				required: presence.value === 'required',
 			}),

Also render the Points at select only when a target exists:

-			{relating && (
+			{relating && target !== undefined && (
 				<SelectControl
 					label={__('Points at', 'gophenberg')}

Keep Validate on scalars, not merged. content.Values.Validate checks each scalar entry against its declared field and value kind. It does not require every field to be present. Validating merged would reject preserved keys absent from active t.Fields with ErrUnknownField, while content.Filled(merged, held, t.Fields) still checks required active fields for published content. Add a regression test for a preserved key after its group stops matching.

test/features/steps_content_fields_test.go (1)

32-67: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Do not create a group while resolving the path of an existing field.

fieldPathOf calls groupOverType, and groupOverType creates a group when no group is titled typeKey + " fields". The relabel, require, delete, and unknown-attribute steps all resolve paths this way. If a scenario declared the field into another group, for example the default group the store raises with the title SingularLabel + " fields", these steps create an empty group and then act on a path inside it. The request answers 404, and the failure names a missing field instead of the real mismatch.

Split the helper: keep the creating form for addField and the reorder step, and use a non-creating lookup for path resolution so an unexpected group layout fails with a clear message.

♻️ Proposed split

+// groupHoldingType returns the group a type's fields already live in.
+func groupHoldingType(ctx context.Context, typeKey string) (int, error) {
+	w, err := worldOf(ctx)
+	if err != nil {

46-53: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

State that the rollback deletes field definitions that no single type names.

The down path derives type_key from location #>> '{0,0,value}', then deletes every row where the result is NULL or names no stored type. A group whose location uses the any-type value, several rule sets, or several rows in one set produces a value that matches no core.content_types.key, so its field definitions are removed. The values those fields hold stay in core.content.fields, but the definitions cannot be recovered by migrating up again.

The loss follows from the shape change, so it may be intended. Record it in the migration notes so an operator takes a backup before rolling back past 00013.

Take the parameter registry from the store instead of a package variable.

locationParams is fixed at package initialization to content.DefaultParamRegistry(nil). Every match in this file (flattenedFields, typesMatchedBy, matchingGroupIDs, groupForType, ownerOf) uses it. The domain Registry accepts a registry through WithParams, so once a second rule source is registered there, the store evaluates the same location rules against a different source set and can select a different group set than the domain layer. Only content_type exists now, so behavior is correct today.

Consider holding the registry on TypeStore and passing it into these helpers, so both layers evaluate rules with the same sources.

Inline comments:
In `@frontend/src/languages/es-ES.json`:
- Line 1: Update the Spanish translation for the theme-pin message beginning
“Your server pins the site to the theme” to replace the incorrect phrase “Tu
servidor bloque el sitio al tema” with a grammatically correct conjugated-verb
translation such as “Tu servidor fija el sitio al tema”, preserving the
placeholders and remaining message unchanged.

In `@internal/content/registry.go`:
- Around line 35-49: Update Registry.Params to synchronize access to r.locations
using the existing r.mu, covering both lazy initialization and the returned
read; preserve the current DefaultParamRegistry creation and choice-generation
behavior while preventing concurrent initialization races.

In `@internal/postgres/content_relations_migration_test.go`:
- Around line 47-48: Update the fixture field lookup in the migration test to
use the ID returned when inserting the `"related"` field, or constrain the query
by the inserted field group so selection is deterministic. Ensure the test
exercises the definition created by its own fixture rather than another field
sharing the same key.

In `@internal/postgres/types.go`:
- Around line 326-337: Update TypeStore.ReorderFields so orders spanning
multiple groups cannot leave matching groups partially reordered: either reject
cross-group keys during validation or apply the requested order to every group
matching typeKey. Preserve the existing single-group behavior and add coverage
for a type matched by two groups.

In `@internal/server/content_helpers_test.go`:
- Around line 490-491: Update the doc comment immediately above
fakeTypeStore.CreateGroup so it starts with CreateGroup and accurately describes
that method’s behavior, removing the unrelated ListGroups description.

In `@internal/server/content_patch_failure_test.go`:
- Around line 113-129: Create a type-scoped group declaring the resting field
used by held.Fields, ensure it matches the post, and deactivate or otherwise
make it non-matching before the PATCH request. Update the test setup around
newFakeTypeStore and stored so the resting value belongs to that inactive group,
while preserving the existing subtitle field and assertions.

In `@internal/server/content_values_test.go`:
- Around line 40-43: Update the rule matching in the groupOver helper to require
rule.Source equals content.ScreenContentType, rule.Operator equals
content.OperatorIs, and rule.Value equals typeKey before returning held.ID;
leave nonmatching rules to continue searching.

In `@languages/fr-FR.po`:
- Around line 868-870: Update the French translation for msgid “Rule %(number)d
of set %(set)d” to use the correct contraction “l'ensemble”, preserving both
interpolation placeholders and the existing meaning.

ListGroups so synthetic type-group IDs and stored group IDs use disjoint fixed
ranges rather than offsetting stored IDs by the current len(s.types). Ensure IDs
remain collision-free when Create registers additional types after groups
already exist, while preserving existing group ordering and lookup behavior.
- Around line 254-282: Update MoveField to confirm that the destination group
identified by toGroup exists before removing the field from the source group.
Preserve the current ErrGroupNotFound and ErrFieldNotFound responses, and only
detach and attach the field after both groups have been validated.

In `@test/features/steps_field_groups_test.go`:
- Around line 236-242: Update theFieldIsNotServedOn to read the served fields
directly, propagate any HTTP or response-decoding error, and return success only
when key is absent from the successfully retrieved fields. Do not treat an error
from the lookup as evidence that the field is withheld.

Greptile Summary

This change adds reusable field groups, location rules, migration support, and administrative workflows for managing grouped content fields.

The former-type cleanup concern was disproved: deleting groups after relocation or deactivation removed obsolete values from live content and revision JSON while retaining values still owned by another active group. The concurrent group-location and field-write collision concerns were also disproved: repeated PostgreSQL races allowed only one conflicting operation to commit, while the other returned content.ErrFieldTaken.

Confidence Score: 5/5

No blocking failure remains.

The exercised deletion and concurrent-write paths preserved field ownership and content cleanup invariants.

T-Rex Logs

What T-Rex did

• Ran the focused regression test TestGroupDeletionPurgesFormerMatchesButPreservesAnotherOwner against a migrated local PostgreSQL; the test exited successfully and showed that former car values lost their subtitle after deletion while the book values retained subtitle because another active group still defined that key.
• Ran a sequential control and 50 synchronized concurrent TypeStore.UpdateGroup races against isolated migrated PostgreSQL databases; in every round both operations waited on the advisory lock before release, afterward exactly one update succeeded, the other returned content.ErrFieldTaken, and exactly one subtitle definition matched the target type.
• Ran synchronized CreateFieldInGroup/UpdateGroup and MoveField/UpdateGroup races 20 times each against isolated migrated PostgreSQL databases; every run recorded one successful operation, one content.ErrFieldTaken, and exactly one overlapping subtitle definition after the concurrent operations completed.
• Execution record shows focused migration-backed PostgreSQL test run in the repository; exit code 0; before deletion car live JSON and both car revision snapshots contained subtitle remove-car and after deletion they contained only their other values; before and after deletion, book live JSON and both book revision snapshots retained subtitle keep-book because the active book group still served that key; the local Compose PostgreSQL service was healthy and accepting connections on port 5435.
• The concurrent output across all rounds showed exactly one successful operation, one ErrFieldTaken, and one committed overlapping subtitle definition for both CreateFieldInGroup/UpdateGroup and MoveField/UpdateGroup races.

Inline comments:
In `@frontend/src/content/GroupFieldsDialog.tsx`:
- Around line 255-263: Update the AddField submission flow around the relating
flag and add mutation so relation fields cannot be submitted when target is
undefined; keep the existing non-relation behavior unchanged and only enable or
execute submission once a valid target is loaded.

In `@internal/postgres/groups_test.go`:
- Around line 160-167: Update the test assertion around held.Fields to also
verify that the returned field’s GroupID matches the first created group,
ensuring the first matching group wins rather than merely checking that one
field is returned.

In `@internal/postgres/groups.go`:
- Around line 226-231: Update CreateFieldInGroup and every database writer that
can create field keys to perform keyFree validation and
TypeStore.CreateFieldInGroup insertion within the same transaction, acquiring
LockFieldGroups before validation. Ensure all field-creation paths use this
serialization so concurrent active groups cannot accept duplicate keys.
