Media Library is a Golang library based on GORM, it will add uploading files to cloud or other destinations with support for image cropping and resizing features to any structs.
It is easy to be extend to support any cloud storages, rightnow, it has filesystem, s3, aliyun, qiniu support.
Media library is using GORM's callbacks to process files, so you needs to register callbacks to gorm DB first, do it like:
import "github.com/jinzhu/gorm"
import "github.com/qor/media_library"
DB, err = gorm.Open("sqlite3", "demo_db") // [gorm](https://github.com/jinzhu/gorm)
media_library.RegisterCallbacks(&DB)Add supprots to structs
// upload file to FileSystem
import "github.com/qor/media_library"
type Product struct {
gorm.Model
Image media_library.FileSystem
}
// Upload file to s3
import "github.com/qor/media_library/aws"
type Product struct {
gorm.Model
Image aws.S3
}And you're done! you could use it like this:
var product Product
if productImage, err := os.Open("product_image.png"); err == nil {
product.Image.Scan(productImage)
}
DB.Save(&product)
// Get image's url, will be s3 url if it is uploaded to s3
product.Image.URL()// Resize images into different sizes when saving images
type ProductIconImageStorage struct{
media_library.FileSystem
}
func (ProductIconImageStorage) GetSizes() map[string]media_library.Size {
return map[string]media_library.Size{
"small": {Width: 60 * 2, Height: 60 * 2},
"small@ld": {Width: 60, Height: 60},
"middle": {Width: 108 * 2, Height: 108 * 2},
"middle@ld": {Width: 108, Height: 108},
"big": {Width: 144 * 2, Height: 144 * 2},
"big@ld": {Width: 144, Height: 144},
}
}Media library could be used alone, and it could works nicely with qor, it you want a admin with CURD support, please check it out!
