DEPRECATION WARNING: Rendering actions with '.' in the name is deprecated

[A5308Y]

Hello there and thanks for prawn-rails!

We're seeing a deprecation warning since a recent rails upgrade:

DEPRECATION WARNING: Rendering actions with '.' in the name is deprecated: .../show.pdf.prawn

We're rendering a file the way suggested in https://github.com/cortiz/prawn-rails/issues/32, but I assume this is an issue with all templates that follow the file naming convention from your docs.

Is this something you're aware of? Are you working on a fix or do you have a suggestion on how to fix the issue on our side?

Thanks in advance and all the best!

Can you show me the call to the render action from your controller code?

Hi @westonganger, thanks for the quick reply. It looks like this:

Admin::ContractsController.render(
  template: "admin/contracts/show.pdf.prawn",
  assigns: {
    decorated_pdf_contract: DecoratedPdfContract.new(@contract)
  }
)

[westonganger]

So you are trying to render to a string? We discussed this in #32

Maybe try one of the following (untested):

render_to_string(
  "admin/contracts/show", 
  formats: [:pdf],
  assigns: {
    decorated_pdf_contract: DecoratedPdfContract.new(@contract)
  }
)

### OR

Admin::ContractsController.render(
  template: "admin/contracts/show",
  formats: [:pdf],
  assigns: {
    decorated_pdf_contract: DecoratedPdfContract.new(@contract)
  }
)

Oh man. This is embarrassing. I tried format (without the "s") and gave up when it didn't work...

template: "admin/contracts/show",
formats: [:pdf],

Works perfectly.

Thanks again for the quick responses @westonganger!
