Why a field_access cannot hide its field everywhere the panel shows it: DeclarationErrorKind::FieldAccess.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Duplicate

Two declarations over one field.

Declare it once, with both its view and its edit rule.

Inverse

The field is the inverse side of a relation, a #[has_many] or a #[has_one], whose records the related resource’s relation table and policy show and link.

Restrict them with the related resource’s policy.

SoftDelete

The field is the soft-delete column, whose state the trash control and the Restore buttons show every user.

Restrict restores and force deletes with the policy’s Restore and ForceDelete.

RecordTitle

The record title reads the field, and every page and relationship choice names a record by its title. Asked of a rule with a view rule only.

Title the record by a field every user may view.

RecordKey

A rule hides a primary key. The key is every record’s URL id and its default label, which every page and relationship choice shows, so no user may be kept from seeing it.

Restrict a field that is not the key.

Watched

A form condition, a dependent choice or another field’s comparison watches the field, so what the form shows or refuses would tell what it holds. Asked of a rule with a view rule only.

Watch or compare with a field every user may view.

UndeclaredReads

A column or a filter of a resource over a model a panel restricts a field of does not declare the fields it reads, so the panel cannot tell whether it shows the restricted one. A custom filter must declare them once any mounted resource restricts a field, of whichever model.

Declare .reading(Reads::of(..)) on a ComputedColumn, a described TextColumn, a row color or a row link, or implement reads on a custom column or filter. A QueryFilter, a tab and a summary read theirs off their predicates.

Fields

what: &'static str

"column", "filter", "row color" or "row link".

name: String

The column’s or the filter’s name.

UnmaskedRelation

A column or a filter reads records of a model a mounted resource restricts a field of, under no field access a panel can mask.

Show the records through a mounted resource: RelationColumn::new::<R> naming the fields it reads, RelationColumn::of::<R> for their title, or a relationship filter over the foreign key. A closure over the row that declares it reads only the row’s own fields reads a copy without its relations, which a page loading them does not refuse.

Fields

name: String

The column’s or the filter’s name.

model: String

The related model’s name.

UnresolvedRelation

A column or a filter reads a relation the mount cannot read off the model’s schema, so it cannot tell whether the relation reaches records a mounted resource restricts.

Declare the relation as a Deferred field of the model.

Fields

name: String

The column’s or the filter’s name.

NarrowedBy

A dependent choice narrows its options by a field a mounted resource restricts, so the options would show which records hold each value of it.

Narrow by a field every user may view.

Fields

field: String

The field the choice narrows by.
