Gorm TableName on dynamic generated strucs

Your Question

Hello! I want to know if it is possible to create a table with relations from a struct created by reflection

I run into the problem that I can't assign a name to it since it doesn't have a Type.Name

The document you expected this should be explained

Expected answer

example:

struct1Fields := []reflect.StructField{
    {
        Name: "field1",
        Type: reflect.TypeOf("string"),
    },
}
struct1 := reflect.StructOf(struct1Fields)
struct2Fields := []reflect.StructField{
    {
        Name: "struct1",
        Type: struct1,
    },
}
struct2 := reflect.StructOf(struct2Fields)
DB.AutoMigrate(reflect.New(struct1), reflect.New(struct2))

my problem is when i try to create that "tables" GORM can't get a properly name to it in MySQL so tries to run a malformed query (CREATE TABLE `` (....)

we tried some ways to implement "Tabler" interface with anonymous fields but isn't possible because when schema tries to parse tablename creates a new *struct value and our anonymous field lose Tabler interface implementation

schema.go:123

modelValue := reflect.New(modelType)
tableName := namer.TableName(modelType.Name())
if tabler, ok := modelValue.Interface().(Tabler); ok {
    tableName = tabler.TableName()
}
if en, ok := namer.(embeddedNamer); ok {
    tableName = en.Table
}
if specialTableName != "" && specialTableName != tableName {
    tableName = specialTableName
}

any idea about how can we solve it? is possible to implement a new Namer strategy with modelType as parameter? like this:

tableName := namer.TableName(modelType.Name())
tableName = namer.TableNameFromType(modelType)
