Why a resource’s tenancy cannot scope its rows: DeclarationErrorKind::Tenancy.

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.

Undeclared

No tenancy declared over a model with a TenantId column, which would serve every tenant’s rows.

Declare Tenancy::column over that field, or Tenancy::none() to serve every tenant.

Fields

model: &'static str

The model’s name.

columns: Vec<&'static str>

The model’s tenant columns.

UndeclaredChild

No tenancy declared over a model that belongs to one a mounted resource scopes by tenant, which would serve every tenant’s children.

Declare Tenancy::via through that relation, or Tenancy::none() to serve every tenant.

Fields

model: &'static str

The model’s name.

relation: String

The belongs_to relation to the tenant-owned parent.

ColumnNotAField

A Tenancy::column lens that names no field of the model.

Name the model’s TenantId field, or use Tenancy::via.

ViaOwnColumn

A Tenancy::via lens that names one field of the model.

Use Tenancy::column.

ViaWithoutBelongsTo

A Tenancy::via lens whose first step is no belongs_to relation.

Start at the relation whose parent holds the tenant.

UnguardedForeignKey

A Tenancy::via resource whose form writes the parent’s foreign key other than through a relationship field over a tenant-scoped resource of the parent’s model.

Write the key through such a choice, so the write re-checks its tenant.

Fields

relation: String

The belongs_to relation the lens steps through.

keys: Vec<String>

The foreign-key columns written another way.
