dude , that some jurasick code, if from 2007?
wow, what the guy is down is checking the myme
type<http://www.iana.org/assignments/media-types/>on the create
action, today that is done in a validation in the model.
params[:photo]['photo']
is something like this
parameter => {:item=>{:name=>"blah blah", :description=> " more blah
blah"},:photo =>{:photo=>[ bunch of data about the file ] } }
at the end in that bunch of that about the file the browser pases the media
type, that is somethie the browser does and they can be
application <http://www.iana.org/assignments/media-types/application/>
audio <http://www.iana.org/assignments/media-types/audio/>
example <http://www.iana.org/assignments/media-types/examples/>
image <http://www.iana.org/assignments/media-types/image/>
message <http://www.iana.org/assignments/media-types/message/>
model <http://www.iana.org/assignments/media-types/model/>
multipart <http://www.iana.org/assignments/media-types/multipart/>
text <http://www.iana.org/assignments/media-types/text/>
video <http://www.iana.org/assignments/media-types/video/>
plus the images can be jpg or tiff
with .content_type =~ /^image/
he is saying grab the media type see if it starts with image, as the browser
pases somthing like this
image/jpg
or
image/tiff
so with
unless params[:photo]['photo'].content_type =~ /^image/
flash[:error] =" that is not an image file "
render :action => 'new'
end
he is checking from the params hash if the file uploaded has a media type of
image. if not render new
