05_update-user-controllers-delete

In this step:

We will delete a user from mongodb.

This is identical to what we did in the last step to GET a user.

First we will get the user id from the URL

id := p.ByName("id")

Next we will Verify that the id is an ObjectId

if !bson.IsObjectIdHex(id) {
	w.WriteHeader(http.StatusNotFound) // 404
	return
}

ObjectIdHex returns an ObjectId from the provided hex representation.

	oid := bson.ObjectIdHex(id)

Next, add code to delete the user

if err := uc.session.DB("go_rest_tutorial").C("users").RemoveId(oid); err != nil {
	w.WriteHeader(404)
	return
}

Run this code

1. Start your server
