  1. Don’t use this on production if you don’t want to be hacked. Passing db through context is a really good idea(!)

  2. Thanks for the Article.. Very valuable..
    Some issues I found are
    1. Importing `gorm` package to books model throws “imported and not used” error.
    2. Since the main function has changed to a route handler, there is no need to import “net/http” package and will throw the same above error.
    3. The `delete` router seems to be missing controller action.

  3. If you want to improve something you need to share the work around as well, not just say the existing stuff is bad.

  4. For your first issue, you can add an underscore alias in front of the gorm import:

    import _ “github.com/jinzhu/gorm”


    One would do this to import “side effects” (static reference) of a module

  5. I found a reflect error when using the UpdateBook method it is because the types are not the same, since we are using an UpdateBookInput struct to update a Book struct. If helps someone in the same situation this is the code i changed:

    Started like this:


    Changed it to this:

    models.DB.Model(&book).Updates(models.Book{Title: input.Title, Author: input.Author})

  6. Thanks, great article.
    May you give some example about relation like one to one, one to many, many to many and etc?

  7. Thanks a lot for your good article.
    Why do you use call by reference somewhere but use call by value another where?
    1. input:

    2. book

  8. models.DB.Model(&book).Updates(input)
    this caused error to me, I have to use json.Marshal(input) as replacement for input.
    In addition, I use gorm.io/gorm and gorm.io/driver/sqlite, and have to modify the database setup to
    database, err := gorm.Open(sqlite.Open(“test.db”))
