I'm making achievement system using gem merit 3.0.1 on Ruby on Rails version 5.1.4. But the problem comes when I'm trying to create User either on POST method or on rails console.
The problem goes `ActiveRecord::RecordInvalid: Validation failed: Sash must exist`. I have followed this link <https://github.com/merit-gem/merit/issues/265> and it says that I have to make the sash optional then pulling the custom merit gem by another github user, and it goes well, until when I see that sash\_id of each user is `nil`, if sash\_id is `nil`, it means the badges cannot make relationship with the user.
What is the problem? I have tried every step that inside the github and stil no clue. Do I have manually create the sash\_id each time User is registered? Thank you.

This is my user model

```
class User < ApplicationRecord
    include Merit
    has_merit

    has_many :activities, dependent: :destroy
    has_many :locations, as: :locationable

    has_many :active_relationships, class_name: "Relationship", foreign_key: "follower_id", dependent: :destroy
    has_many :following, through: :active_relationships, source: :followed

    has_many :passive_relationships, class_name: "Relationship", foreign_key: "followed_id", dependent: :destroy
    has_many :followers, through: :passive_relationships, source: :follower

    def follow(other_user)
        following << other_user
    end

    def unfollow(other_user)
        following.delete(other_user)
    end

    def following?(other_user)
        following.include?(other_user)
    end

    class << self

        def find_for_verfied_token_response(auth,provider,access_token)
            user = find_or_create_by(uid: auth['id'])

            if provider == "facebook"
                user.profile_picture = auth['picture']['data']['url']
            elsif provider == "google_oauth2"
                user.profile_picture = auth['picture']
            end

            user.email = auth['email']
            user.full_name = auth['name']
            user.gender = auth['gender']
            user.provider = provider
            user.access_token = access_token

            puts(user)
            user.save!
            user
        end

        def save_api_key(email,uid,api_key)
            user = User.where(email: email, id: uid).first
            user.api_key = api_key
            user.save!
            user
        end
    end
end
