Instance Method Detail
Allows to read the value of a specific field.
This methods returns the value of the field corresponding to field_name
. If the passed field_name
doesn't
match any existing field, a Marten::DB::Errors::UnknownField
exception is raised.
Allows to return the record associated with a specific relation name.
If no record is associated with the specified relation (eg. if the corresponding field is nullable), then
nil
is returned. If the specified relation name is not defined on the model, then a
Marten::DB::Errors::UnknownField
exception is raised.
Allows to set the value of a specific field.
If the passed field_name
doesn't match any existing field, a Marten::DB::Errors::UnknownField

Macro Detail
Allows to automatically configure creation and update timestamp fields.
This macro will contribute two model fields to the models it is applied to: one created_at
field containing
the creation time of the record, and one updated_at
field containing the update time of the record (which is
also refreshed every time the model is updated).
