登录后 ActiveAdmin 重定向不起作用

Question

For some reason ActiveAdmin returns same login page after successful login:

I thought it's something related with "cancancan" or "acts_as_tenant" so I tried to remove it but it doesn't helped.

I don't added anything special into /initializers/active_admin.rb and tried mostly everything..

Maybe someone had same problem before?

ApplicationController.rb

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  set_current_tenant_through_filter
  before_action :authenticate_admin_user!
  before_action :find_current_tenant, if: -> { current_admin_user }

  def find_current_tenant
    current_account = current_admin_user.business
    set_current_tenant(current_account)
  end
end

Gemfile:

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

Answer 1

Some of my AdminUser's like "superadmins" doesn't have "business_id" (it's set to NULL). That's was the problem, but in my case I really need to have NULL for some users.

So the solution is looking like this.

Code before:

class AdminUser < ApplicationRecord
  belongs_to :business
  validates :business, presence: true

  acts_as_tenant(:business)
end

And after fix:

class AdminUser < ApplicationRecord
  belongs_to :business, optional: true

  # for some reasons it's not working without "on: :create", not sure why
  validates :business, presence: true, on: :create

  acts_as_tenant(:business, optional: true)
end

Hope it will helps someone.
