Tables not getting created in Postgresql using Gorm - go-gorm

Question

I am trying to create a table from a struct using the following code. It had initially worked by hard coding the credentials to test. Once changing to env vars, I wanted to test that the tables and schemas would get created as expected.
So far I have tried:
Removing the tables from the db, running "go run main.go".
Result: Established connection successfully to the db, but tables do not get created.
Deleting the database, recreating the database using psql "CREATE DATABASE" command, and running "go run main.go"
Result: Established connection successfully to the db, but tables do not get created.
Use AutoMigrate, but was not able to successfully create the tables.
Debug: When I run it in debug mode, the debug console displays that its connected, i see no indication of any errors. I have not been coding for many years, still in the learning process.
Below are 2 files, main.go and api.go (opens db)
MAIN.GO
import (
"fmt"
"log"
"net/http"
"time"
"github.com/gorilla/handlers"
"gitlab......"
_ "gitlab....."
)
var err error
func main() {
api := controllers.API{}
// Using env vars from a config file
api.Initialize("user=%s password=%s dbname=%s port=%s sslmode=disable")
// BIND TO A PORT AND PASS OUR ROUTER IN
log.Fatal(http.ListenAndServe(":8000", handlers.CORS()(api.Router)))
if err != nil {
panic(err.Error())
}
// Models
type Application struct {
ID string `json:"id" gorm:"primary_key"`
CreatedAt time.Time `json:"-"`
UpdatedAt time.Time `json:"-"`
Name string `json:"name"`
Ci string `json:"ci"`
// CREATE TABLES AND SCHEMA IF TABLES DO NOT EXIST
if !api.Database.HasTable(&Application{}) {
api.Database.CreateTable(&Application{})
}
API.GO
func (api *API) Initialize(opts string) {
// Initialize DB
dbinfo := fmt.Sprintf("user=%s password=%s dbname=%s port=%s sslmode=disable",
config.DB_USER, config.DB_PASSWORD, config.DB_NAME, config.PORT)
api.Database, err = gorm.Open("postgres", dbinfo)
if err != nil {
log.Print("failed to connect to the database")
log.Fatal(err)
}
fmt.Println("Connection established")
log.Printf("Postgres started at %s PORT", config.PORT)
}
I have already created the database, and am able to establish a connection to the database. Just can not get the tables created.
Ideas?
