Your Question

how to solve computed a field?

My solve

type Exam struct { ID int Name string Point string }

db.raw("select id, name, ST_AsText(ST_centroid(geom)) as point").Scan(&result) this computed field ST_AsText(ST_centroid(geom)) as point

The document you expected this should be explained

Can you decide maybe

type Exam struct { ID int gorm:"primaryKey;column:id" Name string Geom string //postgis geometry field Point string gorm:"computed:ST_AsText(ST_centroid(geom))" maby Total int gorm:"computed:sum(amount)" etc }
