First off, I'm not trying to spec attachment_fu, I know it's been tested.
But, I added some code to that model that I do need to test. Basically,
I need to somehow fulfill the "uploaded_data" property so I can actually
run my tests(otherwise they fail because of validations). The
"uploaded_data" field is what would grab the multipart data from form.
Here it is:
# This method handles the uploaded file object. If you set the
field name to uploaded_data, you don't need
# any special code in your controller.
#
# <% form_for :attachment, :html => { :multipart => true } do
|f| -%>
# <p><%= f.file_field :uploaded_data %></p>
# <p><%= submit_tag :Save %>
# <% end -%>
#
# @attachment = Attachment.create! params[:attachment]
#
# TODO: Allow it to work with Merb tempfiles too.
def uploaded_data=(file_data)
return nil if file_data.nil? || file_data.size == 0
self.content_type = file_data.content_type
self.filename = file_data.original_filename if
respond_to?(:filename)
if file_data.is_a?(StringIO)
file_data.rewind
self.temp_data = file_data.read
else
self.temp_path = file_data.path
end
end
While I was digging I found out that "file_data" is a ruby Tempfile
object. So, I tried to create a dummy file and pass it, but it failed. I
found out in the CGI library, it actually extends the Tempfile object
and adds some methods/properties. It started to get messy, so I thought
I'd ask for advice.
How can I create a valid attachment_fu model spec(so I can start
tweaking it to test my other validations)?
