Chapter 3: uninitialized constant ApiConstraints (NameError)

[phamtony]

Hello,

After bundle install, and then doing rails g devise:install, i get this error (screenshot attached)
Do you know why this would be happening?

[phamtony]

Nevermind, had to put "require 'api_constraints" routes.rb.

I'm facing this same issue, and I'm a little confused about the solution. Are you saying you need to add "require 'api_constraints' inside the routes.rb file?

[kurenn]

Yes the solution is to add the api_contraints.rb file on the routes, something like:

require 'api_contraints.rb'
Rails.application.routes.draw do

end

[dgoradia]

I'm getting this same error when doing bundle exec rspec lib/spec/api_constraints_spec.rb. I already have require 'api_constraints' in my routes.rb file.

$ bundle exec rspec lib/spec/api_constraints_spec.rb 
/Users/dgoradia/api/lib/spec/api_constraints_spec.rb:3:in `<top (required)>': uninitialized constant ApiConstraints (NameError)

I got the same issue @dgoradia-atlas. I think the problem is on the gem version?

[dgoradia]

@pcofilada I think the issue is that I'm using a newer version of RoR. Here is how I fixed it:

In lib/spec/api_contraints_spec.rb, replace:

require 'spec_helper'

with:

require 'rails_helper'

And I added the following to spec/spec_helper.rb since I'm not familiar with the new syntax yet:

expectations.syntax = :should

[pcofilada]

It's now working @dgoradia-atlas . I think I should use new syntax for my test.

Hey guys, I'm having the same error. Can someone help me out? I tried the code that pcofilada and dgoradia shared. It doesn't work, maybe I'm missing something or because of the newer version.

Yes the solution is to add the api_contraints.rb file on the routes, something like:

require 'api_contraints.rb'
Rails.application.routes.draw do

end

please update the spelling of constraints.
