Constructor Details

#initialize(patient, view_context) ⇒ ProtocolPresenter

We must delegate unknown method calls to view_context in order to handle e.g. .formats (required by our #with_format method) and to avoid errors if any link_to etc helpers are called.

#with_format(format, &block) ⇒ Object

In order for pdf rendering to easily re-use html partials (despite a mime type of :pdf), pass partial rendering code as a block to ‘with_format`.

Example issues and usage trying to render my_partial.html.slim from my_template.pdf.slim:

= render 'my_partial' # cannot resolve the html partial

= render 'my_partial', format: :html # resolves partial but i18n requires an `html:` key

- with_format(:html) do
  = render 'my_partial' # resolves the html partial and existing i18n keys are used.
