# Ran into an issue recently where I wanted to use our custom prawn class to generate a PDF, then upload it to Amazon S3 using paperclip.
# Let 'OurCustomPdf' be our prawn class.
# Let the variable '@user' be our our model, has_many :documents
# Let 'Document' be our paperclip model, belongs_to :user
