[Borges-users] borges+ming = swf on the fly

[Слепнев Владимир]

Hi,

some days ago I tried to use Borges+Ming to generate Flash (.swf) 
content from numerical data (taken from a database) on the fly, and 
show it in a component. It's easy. Here's how.


def flash_graph(r, blah blah blah)  # r is the HTMLBuilder passed to 
render_on

# create an SWF movie, called m, with Ming, from blah blah blah... 
then do this:

	tf = Tempfile.open("blahblah",".")
	tf.binmode
	m.save(tf.path)
			
	r.set_attribute :src, r.url_for_document(tf.read, 
"application/x-shockwave-flash")
	r.set_attribute :width, w
	r.set_attribute :height, h
	r.tag "embed"
			
	tf.close(true)
end


(A possible enhancement would be to use a customized RequestHandler 
for the SWF data, to make it expire properly...)

Also, if anyone's in need of a Ming+Ruby build on Windows (this can't 
be obtained from the Ming website), I have it, you only have to ask. I 
made it myself. Not exactly an easy task :-)
