All validator function

Base on

  1. asaskevich/govalidator: [Go] Package of validators and sanitizers for strings, numerics, slices and structs (github.com)
  2. thedevsaddam/gojsonq: A simple Go package to Query over JSON/YAML/XML/CSV Data (github.com)

Example ​

go
package requests

import (
  "gitlab.finema.co/finema/golang-template/models"
  core "gitlab.finema.co/finema/idin-core"
)

type UserCreate struct {
  core.BaseValidator 
  Email    *string `json:"email"`      // Email field for user creation
  FullName *string `json:"full_name"`  // Full name field for user creation
}


func (r *UserCreate) Valid(ctx core.IContext) core.IError {
  // Check if the email is valid format
  r.Must(r.IsEmail(r.Email, "email"))
  
  // Check if the email is not empty
  r.Must(r.IsStrRequired(r.Email, "email"))
  
  // Check if the email is unique in the database
  r.Must(r.IsStrUnique(ctx, r.Email, models.User{}.TableName(), "email", "", "email"))

  // Check if the full name is not empty
  r.Must(r.IsStrRequired(r.FullName, "full_name")) 

  return r.Error()
}
go
package user

import (
	"gitlab.finema.co/finema/golang-template/requests"
	"gitlab.finema.co/finema/golang-template/services"
	core "gitlab.finema.co/finema/idin-core"
	"gitlab.finema.co/finema/idin-core/utils"
	"net/http"
)

type UserController struct {
}

func (m UserController) Create(c core.IHTTPContext) error {
	// Create an instance of UserCreate struct to hold the request data
	input := &requests.UserCreate{}

	// Bind the request body to the input struct and validate the input
	if err := c.BindWithValidate(input); err != nil {
		return c.JSON(err.GetStatus(), err.JSON())
	}

	// Create an instance of UserService
	userSvc := services.NewUserService(c)

	// Create a payload to pass to the userSvc.Create method
	payload := &services.UserCreatePayload{}
	_ = utils.Copy(payload, input)

	// Call the userSvc.Create method to create a new user
	user, err := userSvc.Create(payload)
	if err != nil {
		return c.JSON(err.GetStatus(), err.JSON())
	}

	// Return the created user as JSON response
	return c.JSON(http.StatusCreated, user)
}

Example response (Return HTTP Status 400) ​
