I'm working on an import utility that will match the functionality of
uploading an object of a model that uses attachment_fu for
Rather than uploading the file via a form, I want to populate the
params[:image][:uploaded_data] with data from a file already on the
server's file system.
So far, I've been able to copy to an instance of Tempfile via the
copy_to_temp_file method I jacked from attachment_fu and pass that as
the value of :uploaded_data, but attachment_fu is still not happy.
The Tempfile created via a multipart form and a browser has
content_type set, as well as having the path be how the object is
identified (i.e. - #<File:/tmp/file/path>).
I feel like I've either reached a dead end and I have to explore
setting size, original_filename, and content_type explicitly in the
new method parameters or that I'm just bumping up against my ignorance
and there is a better way I don't know about.
I noticed that there are mechanisms for this fake out in testing code,
perhaps I'll give them another look.
