uninitialized constant Cell::Testing::Uber (NameError)

[CJYate]

I'm seeing a problem when using cells with rspec-cells.
After creating the repo and a scaffold, I created a cell:

00:37 $ rails g cell thing
      create  app/cells/thing_cell.rb
      create  app/cells/thing/show.erb
      invoke  test_unit
      create    test/cells/thing_cell_test.rb

But I want rspec tests, so after installing rspec-rails:

00:25 $ rails g cell thing2
create app/cells/thing2_cell.rb
create app/cells/thing2/show.erb
error rspec [not found]

What do to? Install rspec-cells, maybe? After that:

00:28 $ rails g cell thing2

Any ideas?

In order to show the Gemfile etc I've uploaded my bug-demo repository at https://github.com/CJBrew/cell_rails.

Ubuntu system with Rails 4.2.4

I saw this: #270

Have tested with the github link in my Gemfile and it doesn't appear to solve the problem,

[apotonick]

You're not including the cells gem! See here: https://github.com/apotonick/cells#installation

/facepalm

For some reason that wasn't clear enough. Thank you.

@apotonick, thanks for the pointer to the cells gem; however there still seems to be an issue with generating Concepts (sorry, I deleted my example repo).

It's this issue: trailblazer/rspec-cells#57

01:54 $ rails g concept Frog get post
      create  app/concepts/frog/cell.rb
      create  app/concepts/frog/views/show.erb
      create  app/concepts/frog/views/get.erb
      create  app/concepts/frog/views/post.erb
       error  rspec [not found]

I'm not really sure what I gain from using Concepts over Cells -- what I'm really after is a nice ViewModel-like layer.

[apotonick]

Concept cells are cells that follow the Trailblazer file and naming layout: https://github.com/apotonick/cells#concept-cells They are basically identical to normal cells but instead of CommentCell, they use namespacing, e.g. Comment::Cell.

same issue using trailblazer
added rspec-cells gem

/gems/bundler-1.12.5/lib/bundler/runtime.rb:89:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'rspec-cells'. (Bundler::GemRequireError)
Gem Load Error is: uninitialized constant Cell::Testing::Uber

[apotonick]

Cool @agm1988 that might help me fixing the issue!

Thanks @agm1988 for following up on this. Can you please test cells/master if it works for you?
