MssqlRelationKind enum

The relation shapes, matching the vocabulary Eloquent uses.

The pairs that look redundant are not. hasOne and hasMany are the same foreign key in the same direction; what differs is whether the other side can hold more than one row per parent, which a unique constraint on its foreign key columns settles. Every morph* and *Through shape is declared rather than derived, because no foreign key expresses them.

Values

belongsTo → const MssqlRelationKind

A foreign key on this table points at another's primary key. Eloquent: belongsTo.

hasOne → const MssqlRelationKind

A foreign key on another table points back at this one, and that side is unique, so there is at most one. Eloquent: hasOne.

hasMany → const MssqlRelationKind

A foreign key on another table points back at this one. Eloquent: hasMany.

belongsToMany → const MssqlRelationKind

Through a pivot table carrying both sides' keys. Eloquent: belongsToMany.

hasOneThrough → const MssqlRelationKind

A → B → C, where C is reached through B and there is one. Eloquent: hasOneThrough.

hasManyThrough → const MssqlRelationKind

A → B → C, many. Eloquent: hasManyThrough.

morphTo → const MssqlRelationKind

This table carries a type column and an id column naming one of several possible parents. Eloquent: morphTo.

morphOne → const MssqlRelationKind

The inverse of morphTo, with one child. Eloquent: morphOne.

morphMany → const MssqlRelationKind

The inverse of morphTo, with many. Eloquent: morphMany.

morphToMany → const MssqlRelationKind

Through a pivot whose rows also carry a type column. Eloquent: morphToMany.
