Unable to use _iteration with with_collection_parameter

[AndreaBarghigiani]

I don't know if this is the right approach but I am trying to create a container for the components rendered with a with_collection, the base idea was to leverage the first? and last? methods of PartialIteration in order to create my container.

Anyway, this is my component:

class ChecklistAnswerComponent < ViewComponent::Base
  with_collection_parameter :data

  def initialize(data:, data_iteration:)
    @data = data
    @iteration = data_iteration
  end
end

As you can see it is really simple but the thing that I do not understand is why _iteration does not work, if I use data_counter everything works as expected but I really cannot figure out why does not work the iteration as well.

Does any of you have an idea of why it is happening or probably have a better way to create a container for a with_collection?

Seems to me like you're doing the right thing here according to the docs. Maybe there's an underlying issue at play here?

If you could pull together an isolated example repo (e.g. by starting with rails new --minimal), that'd be really helpful in diagnosing this. If it turns out there's something up with ViewComponent itself, we can turn this discussion into an issue and see where it goes.

@boardfish thanks for the quick response and the advice.

Set up the --minimal repo and everything worked out of the box. Turns out that in the project I am working on we used ver 2.24 and even if I checked #306 I didn't notice when this has been merged.

I've updated ViewComponent and everything started to work.

So lesson learned: keep your gem updated 😂
