Apartment: TenantNotFound - One of the following schema(s) is invalid

问题

I am using the Apartment Gem for the first time for Multitenancy in a Ruby on Rails project. I am trying to create multiple tenants for users in your digital library Rails application.

I am using Devise Gem for the authentication of the application, and I have generated the and I have generated config file by running the code below in my terminal

rails generate devise:install

I have also generated a User model for Devise using the code below in my terminal

rails generate devise User

And for the Apartment Gem, I have installed it and generated the config file by running the code below in my terminal

bundle exec rails generate apartment:install

I have also configured the config/initializers/apartment.rb initializer file as needed using the documentation provided, and I have created a new tenant via my signup page at

localhost:3000/users/sign_up

But when I try viewing the newly created tenant at

http://newtenant.lvh.me:3000/

I get the error below

Apartment::TenantNotFound(One of the following schema(s) is invalid: "" "public")

I have tried to figure out the cause of the issue, but I still haven't been fortunate to get it fixed. I need some help. Thank you in advance.

回答1:

Here's how I fixed it

I simply added an after_create callback called create_tenant to the model of the subdomain for my multi-tenant, which is user.rb in app/models/user.rb

class User < ApplicationRecord
  after_create :create_tenant

  private

  def create_tenant
    Apartment::Tenant.create(subdomain)
  end
end

Use this if you used Devise for Authentication

class User < ApplicationRecord
  after_create :create_tenant

  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable

  private

  def create_tenant
    Apartment::Tenant.create(subdomain)
  end
end

N/B: My model name for the Tenant is User, your model name may be different, so check through your app/models/ to see the model name that you used for the multi-tenant

You can try creating new tenants again, and everything should run fine.

This advice below may apply to only those who used Devise for authentication or to every other person using an authentication system

If you run into any issue like this

Filter chain halted as :require_no_authentication rendered or redirected

when trying to fix this issue of Tenant Not Found, simply restart your local server by using the code below

rails server

and then visit the link below to edit your newly created users/tenant

localhost:3000/users/edit

N/B: The users in localhost:3000/users/edit represents the plural name (table) of the model that I used for my multi-tenant.

When the page opens up, simply Delete/Cancel the Account and then that you've created already.

Now you can try creating new tenants again, and everything should run fine.

That's all.

I hope this helps
