Struct ResolvedRelation

pub struct ResolvedRelation {
    pub source_model: String,
    pub source_field: String,
    pub target_model: String,

Expand description

One forward (BelongsTo) relation resolved against the schema.

Carries enough information for the admin to:

  1. render the FK column (target_model, target_table, target_display_field);
  2. link to the target’s detail page (target_admin_name);
  3. issue the batched prefetch query for list pages.

Everything is owned String rather than &'static str because the registry is built from a parsed Schema whose String fields outlive the registry. Copying costs once at schema-reload time and buys simple lifetimes everywhere else.

Fields§

§source_model: String

Model name holding the FK column, e.g. "Appointment".

§source_field: String

Field on the source carrying the id, e.g. "patient_id".

§target_model: String

Target model name, e.g. "Patient".

§target_table: String

Target model’s SQL table, e.g. "patients".

§target_admin_name: String

Target model’s admin slug, e.g. "patients" — what appears in /admin/<slug>/<id> URLs.

§target_display_field: Option<String>

Column on the target whose value is rendered as the human label. None means the admin renders #<id> and does NOT infer a column — display-field guessing is explicitly off.

§kind: RelationKind

Direction marker. Always BelongsTo for forward relations.
