I am building model too and it has everything you mentioned :) But it is not ready yet. #96 is what I already have and it can already do simple queries - https://github.com/go-pg/pg/blob/feature/pg-v4/db_test.go#L176-L191. Any help is appreciated but code is not documented (but it should be clean and readable).

Great! Hope your model layer will fit my requirements, but now I'm bound to existing codebase.
Anyway, what do you think about opening in terms of layers?
I've inspected code changes on master and found that index became unexported. It's great to know field depth as I need only top level fields. To achieve this we can define:
func (f *field) IsTopLevel() bool {
return len(f.index) == 1
}
With this func we can iterate through fields.List
and filter top level fields. But index values would be required someday too. So, I'm for making it exported. And I still need a way to get fields. Maybe something like this?
func FieldsForType(typ reflect.Type) fields {
return structs.Fields(typ)
}
from pg.
If you are bound to existing codebase then it is easier to just fork the lib and export whatever you need since it is very unlikely that v3 will receive big updates.
Anyway, what do you think about opening in terms of layers?
In v4 I plan to export those API in a subpackage so it does not clatter main API, e.g.:
import "gopkg.in/pg.v4/orm"
article := &MyArticle{}
table := orm.Tables.Get(reflect.TypeOf(article))
for _, field := range table.Fields {
fmt.Println(field.Name)
fmt.Println(field.GetValue(article)) // returns reflect.Value
}
from pg.
This info is now exported in v4. You can start from reading Table definition https://godoc.org/gopkg.in/pg.v4/orm#Table
from pg.
