I am facing an issue with my Angular 1.5 application and Rails 4.0 backend. During testing, when a Staff member logs in, three queries are simultaneously sent to the backend causing errors. Strangely, this issue does not occur in the development environment.
One such error example is:
NoMethodError at /entities/get_current_entity
=============================================
> undefined method `fields' for nil:NilClass
app/controllers/application_controller.rb, line 79
--------------------------------------------------
ruby
74
75 private
76
77 def set_locale
78 #I18n.locale = params[:locale] if params[:locale].present?
> 79 if current_staff.nil? or current_staff.locale.nil?
80 I18n.locale = "en"
81 else
82 I18n.locale = current_staff.locale
83 end
84 end
App backtrace
-------------
- app/controllers/application_controller.rb:79:in `set_locale'
<Snip>
The failing test scenario looks like this:
require "rails_helper"
RSpec.describe "Login", :type => :feature do
describe "login with existing staff member" do
before do
create_admin
end
it "logs in as admin" do
visit "#/login"
fill_in "Email", with: "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d7b6b3babeb997a3b2a4a3f9b4b8baf9b6a2">[email protected]</a>"
fill_in "Password", with: "password"
click_button "Login"
within "#staff-status" do
expect(page).to have_text('LOGOUT')
end
within("#flash-messages") do
expect(page).to have_text('Successful login')
end
# Check session variables
within("#selected-entity") do
expect(page).to have_text("LOGIN DEFAULT COMPANY")
end
within("#selected-ledger") do
expect(page).to have_text("My Ledger")
end
within("#selected-division") do
expect(page).to have_text("1-General")
end
</end>
end>
end>
This problem occurs consistently throughout the application after upgrading to Rails 4 from Rails 3.2. When utilizing promises, the issue doesn't arise, but implementing promises for all data retrieval slows down the application significantly.
As a workaround for login issues, the following code snippet can be used:
Auth.currentUser().then((staff) ->
FirmService.current_entity($rootScope).then ->
DivisionService.current_division($rootScope).then ->
LedgerService.current_ledger($rootScope)
To handle simultaneous requests during testing in Rails 4, you may try running the server in the test environment. However, updating gems such as capybara, selenium-webdriver, and chromedriver-helper did not resolve the issue.
If errors persist, further debugging through techniques like inserting 'binding.pry' into controllers and analyzing pry hanging instances should provide insight into the root cause of the problems.
