How to set user before require_tenant check?

[seanarnold]

I want to conditionally set require_tenant based on a user attribute. i.e all non-admins need to have a Tenant explicitly set.

ActsAsTenant.configure do |config|
  config.require_tenant = lambda do
    Current.user && !Current.user.admin?
  end
end

class ApplicationController < ActionController::Base
  set_current_tenant_through_filter
  before_action :authenticate_user!
  before_action :set_tenant_record

  def authenticate_user!
    ActsAsTenant.without_tenant do
      super
      # Set a global var as `current_user` isn't available in initialiser 
      Current.user = current_user
    end
  end

  def set_tenant_record
    set_current_tenant(current_user.tenant)
  end
end

However require_tenant is evaluated when authenticate_user! is called, even though it's within a without_tenant block.
As Current.user is nil, the lamba evaluates to false.

How do I set my Devise user before the require_tenant lambda is evaluated?

running into a similar issue, I have a primary and a secondary tenancy and need to determine which one to apply by looking into the current_user roles first

I had a similar need. This is my solution in case it helps anyone else

The initializer checks if the Current.user has been set. If so, it requires a tenant.
conf/initializers/acs_as_tenant.rb

# Only require the current_tenant to be set once a user has logged in
ActsAsTenant.configure do |config|
  config.require_tenant = lambda do
    Current.user.present?
  end
end

The application controller sets the Current.user from the current_user variable provided by devise in each request.
app/controllers/application_controller.rb

class ApplicationController < ActionController::Base
  before_action :authenticate_user!
  before_action :set_current_user

  private

  # Set Current.user from devise
  def set_current_user
    Current.user = current_user
  end
end

Setting the Current.user also sets the Current.account and current_tenant
app/models/current.rb

class Current < ActiveSupport::CurrentAttributes
  attribute :user, :account

  # Sets the user and associated account in the Current object.
  # Also sets the current tenant for ActsAsTenant.
  def user=(user)
    super
    self.account = user&.account
    ActsAsTenant.current_tenant = user&.account
  end
end
