Cannot render Rails env variable within cell

[chrisyeung1121]

I have a following cell class

class PromotionRuleCell < Cell::ViewModel

  def selector
    render
  end

  def all_subclasses
    Rails.env.development? ? [
        Promotion::Rules::RentTime,
        Promotion::Rules::RequestTime,
        Promotion::Rules::RentDuration,
        Promotion::Rules::TargetCar
        ] : PromotionRule.subclasses
  end

end

I basically have to access Rails.env variable but since Rails has become a module under Cell::Slim::Rails:Module I can't access Rails.env now. Is there any way to work around this?

Use :: Rails.env.development?

I tried using :: Rails.env.development?
It also results in NoMethodError: undefined method 'all_subclasses' for #<ActiveSupport::SafeBuffer:0x007f846c266360>

Sorry, I put a space into that by mistake. It should had been:

::Rails.env.development?

[chrisyeung1121]

I tried that as well. It all result in the same error :(

Wait, I didn't read your error message properly before.. Where are you calling all_subclasses from?

The ::Rails syntax is definitely correct, I'm using that in my own project.

I am calling it from spec/cell/. Is it not included in test ?

What happens when you call ::Rails::env - this will work, that's pure Ruby and no Cells involved.

[chrisyeung1121]

If I just run ::Rails::env in console it works fine. If I run it from bundle exec spec It just gives me the same error.

Failures:

  1) PromotionRuleCell
     Failure/Error: it { expect(cell(:promotion_rule).(:selector).all_subclasses).to eq(4) }

     NoMethodError:
       undefined method `all_subclasses' for #<ActiveSupport::SafeBuffer:0x007fc63be6f8a8>
     # ./spec/cells/promotion_rule_cell_spec.rb:6:in `block (2 levels) in <top (required)>'

Finished in 0.3323 seconds (files took 6.01 seconds to load)
1 example, 1 failure

Failed examples:

rspec ./spec/cells/promotion_rule_cell_spec.rb:6 # PromotionRuleCell

This is my spec file if it helps

require 'rails_helper'

RSpec.describe PromotionRuleCell, type: :cell do
    subject { cell(:promotion_rule).(:selector) }

    it { expect(cell(:promotion_rule).(:selector).all_subclasses).to eq(4) }
end

Of course, because this is wrong! 😜

cell(:promotion_rule).(:selector) will return a Capybara-assertable string.
cell(:promotion_rule) returns the cell instance. That's what you want.
