I would like to write some unit test with a logged user using Authlogic. To start right, I used some code hosted in http://github.com/binarylogic/authlogic_example. But I get an error after rake test, because of "test_helper.rb" and the following class:
class ActionController::TestCase
setup :activate_authlogic
end
Here is my error:
NameError: undefined local variable or
method `activate_authlogic' for
I think this Authlogic example is mapped over Rails 2; maybe it's a little bit different on Rails 3. Is there an other example where I can take example about unit test?
Many thanks.
Do you require 'authlogic/test_case' and include Authlogic::TestCase?
I had a similar issue (using rspec, though) and read through the code at http://github.com/trevmex/authlogic_rails3_example
As of Rails 3.1 and Authlogic 3.0.3, the only thing I've had to add to activate authlogic was
features/support/env.rb
Before do
activate_authlogic
end
I don't realize where to put include Authlogic::TestCase, so I put this after the requires in spec_helper.rb and it worked. There is a better place for it?

I am trying to create an integration test with Capybara/RSpec that has a valid current_user (using the Warden.test_mode! trick) and I have also created a valid current_tenant by doing this in the test:
ActsAsTenant.current_tenant = Account.first
When the test is ran it comes up with a "undefined method for nil:NilClass" error that is characteristic of the current_tenant not being set. I have verified that Account.first does in fact have what I expect in it.
What might be the problem and how can I fix it?
You can check the gem 'act_as_tent' doc over here
https://github.com/ErwinM/acts_as_tenant#testing
You might need to create the Account. If you're using FactoryBot, that might look like:
ActsAsTenant.current_tenant = FactoryBot.create :account
You might also consider using:
ActsAsTenant.without_tenant do
# more testy things
end
I have a Customer_ratings model that allows users to leave feedback on each other. The web app is working properly, and feedback is collected, stored and displayed.
I wanted to go in and delete some feedback through the rails console, but when I enter Customer_rating.all, I get the following error:
LoadError: Unable to autoload constant Customer_rating, expected /Users/myapps/app/models/customer_rating.rb to define it
Similarly, if I enter Customer_rating[0], I get:
RuntimeError: Circular dependency detected while autoloading constant Customer_rating
I don't have this issue while accessing other tables through my console.
What could be causing the issue, and why wouldn't this error prohibit Customer_ratings from working properly through the web app?
It seems like a case of messed up naming convention.
As per Rails naming convention, file names should be in snake_case and class names in CamelCase. In your scenario, the file name should be customer_rating.rb and class name should be CustomerRating.
After making these changes, use CustomerRating.all(as the updated class name is CustomerRating) to fetch all the customer ratings. Do not use Customer_rating.all.
I'd also like to add a scenario of this problem that I found for future reference.
I'm running Rails 4.0 and I had this same problem but what happened was I had a model named Student inside student.rb that was contained in a folder called Student. I didn't realize it at first but the folder name was the problem. Changing the folder name to something other than a model name solved the problem.
If the naming convention is not off, like in this question, it may be an issue on initial first load if you're making a lot of requests at the same time. I experienced this with nested controllers Api::LocationsController.
I solved it by enabled eager_load in development env:
Rails.application.configure do
...
# Enabled this to avoid crash unable to autoload controller
# Error happens when you start and stop server on initial requests
# solution found via https://github.com/rails/rails/issues/32082#issuecomment-367715194
config.eager_load = true
I based this off of rails issues comments: https://github.com/rails/rails/issues/32082#issuecomment-367715194
You just need to modify the name of the Module
For example if the link is http://sairam.esy.es/users/customer_rating then
you controller should like be
module Users
class RatingController
# ...
def customer_rating
# ...
end
# ...
end
end
I make an application writed in Rails, it's growing fast and I learning with it. But I'm don't understand about helpers.
application_helper.rb
module ApplicationHelper
# This file it's empty
end
users_helper.rb
module UsersHelper
def avatar
# Do something
end
end
customer_helper.rb
module CustomerHelper
# This file it's empty
end
Why in any customer's view can call avatar helper method on user helper module?
Then, why separate helpers in many files?
Thanks in advance.
P.S: Rails' version 4.
Because all helpers are included in all controllers, by default. The separate files are really just for logical separation in this scenario. You can change that behaviour though:
By default, each controller will include all helpers.
In previous versions of Rails the controller will include a helper
whose name matches that of the controller, e.g., MyController will
automatically include MyHelper. To return old behavior set
config.action_controller.include_all_helpers to false.

To add to Mike Campbell's answer:
Framework
As magic as it is, Rails is a set of files which are called
sequentially
These files hold classes, methods, etc; but they're still files.
And that means that when you run an action through Rails, it loads up
a series of other dependent files to help it run (that's what a
framework is)
The design of Rails is such that your helper methods are all
loaded each time you run an action. I don't know why, but it helps
administer the methods for different areas of your app
So to answer your question, there's no real reason why the helpers are split up, at least with Rails 4
I have a Rails 4.1.0 mountable engine. In the engine's application_helper.rb:
module MyEngine
module ApplicationHelper
def test123
"test123"
end
end
end
The method is in the dummy app's view general/index.html.erb view:
%<= test123 %>
This works. However, when I change the string returned by def test123 and refresh the browser, the new string is not displayed.
Of course, restarting the web server in the dummy app shows the new string.
So the question is, how to reload the engine's files without having to restart the web server?
PS. I am preferably looking for a way to do this using Rails itself, or a specific gem that solves this problem (but not the generic gems like Guard, Spork etc. although if all else fails, I will consider those too.)
PPS. There are similar questions on SO, but I have tried them all (even though they are for Rails 2.x, 3.x), and they have not worked for me.
You should explicitly require dependent helpers:
# engines/my_engine/app/controllers/my_engine/application_controller.rb
require_dependency "my_engine/application_helper" # This is a key point!
module MyEngine
class ApplicationController < ::ApplicationController
helper ApplicationHelper
...
you can use some thing like zeus which is helping a lot in watching project files for changes except in some cases when you change the configuration files it doesn't work and needs to be manually restarted.
but overall in most cases this works more than awesome
When using sinatra-r18n to handle internationalisation, the r18n lib exposes a variable t for use within your helpers, routes and templates, as per these instructions.
I have written a simple unit test using rack-unit to confirm that some of my pluralisations work but the test throws an error claiming t is nil.
I've tried referencing it via app.t, MySillyApp.t (where MySillyApp is the name of my Sinatra app), MySillyApp.settings.t etc and none of them give me access to the t I need.
What I am trying to achieve is a confirmation that my translation files include all the keys I need corresponding to plurals of various metric units my app needs to understand. Perhaps there is a more direct way of testing this without going via the Sinatra app itself. I'd welcome any insight here.
I had similar task to check localized strings in my Cucumber scenarios.
I've made working example.
Here you can find how strings got translated.
This file halps to understand how to add R18n support to your testing framework:
require 'r18n-core'
...
class SinCucR18nWorld
...
include R18n::Helpers
end
As you can see instead of rack/unit I'm using RSpec/Cucumber, sorry.
