hi all just working on my first camping hack and new to ruby as well. i've figured some things out and uploading images into the database, but i'm not sure how to get the data displayed in the browser. i'd like to stream it straight from the db, not copy it to the fs first. obviously img(:src => file_data) doesn't work. any pointers or reading assignments would be v. welcome. many thanks cornelius
Make a controller with a get method to retrieve the image, then, have some code like this in it, supposing image_data is a string or something: headers['Content-Type'] = 'image/png' headers['Content-Length'] = image_data.length.to_s return image_data On 03/02/2009, at 10:58 AM, Cornelius Jaeger wrote: > hi all > > just working on my first camping hack and new to ruby as well. > i've figured some things out and uploading images into the database, > but i'm not sure how to get the data displayed in the browser. > i'd like to stream it straight from the db, not copy it to the fs > first. > obviously img(:src => file_data) doesn't work. > any pointers or reading assignments would be v. welcome. > many thanks > > cornelius > _______________________________________________ > Camping-list mailing list > Camping-list@... > http://rubyforge.org/mailman/listinfo/camping-list
Well, you could sorta do img(:src => file_data), using the data: URI scheme.
def data_uri(file_data, mime_type="image/png")
"data:#{mime_type};base64,#{[file_data].pack('m*')}".strip
end
Then you could just do img(:src => data_uri(file_data)), and it should work.

Mmm, indeededly, though data: uri's don't work at all in internet
explorer, quite the bummer if you care :)

Hi Jenna, Roland Thanks for your responses. How can I get the image inline in the html, rather than downloading it to the user? I'm not at all sure how to use markaby to stream the image data into something the img tag will understand.

Roland just showed you how to inline it.
Here's a little article on the technique he's using:
http://jimbojw.com/wiki/index.php?title=Data_URIs_and_Inline_Images
However, as Jenna said, this technique doesn't work in IE. Her first suggestion is probably the path of least resistance.

Hello folks! Just checking - I understand that Camping 2.0 entered the phase of perpetual polishing and will not likely happen, anytime soon, but would there be a possibility to at least have 1.5.180 on Robyforge for official installs instead of _why's repo? I just tried to deploy my blog just with "gem install camping" by mistake and been literally plagued by bugs in 1.5.x on forge, including the infamous "query-string-params-totally-mixed-with-path-for-R" problem and "all-my-images-appear-blank" problem. Pretty pretty please? -- -- Julik Tarkhanov me@...
Yes, we should release 2.0 soon... Meanwhile you can always download 2.0 using my repo: gem install camping --source http://gems.judofyr.net/ //Magnus On 10. feb.. 2009, at 06.50, Julik Tarkhanov <julian.tarkhanov@...> wrote: > Hello folks! > > Just checking - I understand that Camping 2.0 entered the phase of > perpetual polishing and will not likely happen, > anytime soon, but would there be a possibility to at least have > 1.5.180 on Robyforge for official installs instead of _why's repo? > > I just tried to deploy my blog just with "gem install camping" by > mistake and been literally plagued by bugs in 1.5.x on forge, > including the > infamous "query-string-params-totally-mixed-with-path-for-R" problem > and "all-my-images-appear-blank" problem. > > Pretty pretty please? > -- > Julik Tarkhanov > me@... > > > > > > _______________________________________________ > Camping-list mailing list > Camping-list@... > http://rubyforge.org/mailman/listinfo/camping-list
