Updates on Rails S3 Flash upload plugin

Hey great plugin, appreciate all the work you've done and appreciate you sharing it with the rails community. I've got everything working perfectly as expected. There is only one thing I had a question with. What would be the recommended way to set the Content-Type on the upload? I want the files uploaded to be down loadable instead of playing or showing in the browser. With S3 if you set Content-Type to application/octet-stream you will get files to download. all I need to know is where in the code I should look.

Hi, jeff, good question, the content type is determined by file select control in the flash, and it will be sent to S3UploadsController in your rails app for generating signature, so if you like to customize the content type, what you only need to do is changing Line 11 in S3UploadsController, it should looks like:

content_type = params[:content_type]

hope this helps.

Thanks for the speedy reply. I tried changing what you suggest, but every time it uploads a file now it just returns an error. That's why I was wondering if there was some other place where this value is being used. I'm thinking that when I do what you described perhaps there is a difference in the post request and the policy that was generated...

figured it out for anyone that cares. If you want to make sure the mimetype is always "application/octet-stream" you have to open up

vendor/plugins/s3-swf-upload-plugin/flex_src/src/s3_upload.mxml

and change line 51 to

options.ContentType = "application/octet-stream";

and

line 82

variables.content_type = "application/octet-stream";

then compile and move the swf into your public directory.. Hope this helps other people..

Yes, you're right, only changing controller shouldn't work because the policy difference.

Thanks for your solution, Jeff.

Has anyone had any luck using two of these on the same page? I'm running into JavaScript funkiness and I don't know the source well enough to tweak it myself.

I'm trying to do something along the lines of:

<%= s3_swf_upload_tag %>
<%= s3_swf_upload_tag %>

Kelly, thanks for your comment, s3_swf_upload now is capable for inserting 2 upload tag in one page.

Is it possible to have the name of the file that the user typed passed out as a parameter to the callbacks?

My application needs to know the name of the file that the user uploaded!

Thanks!

Ah - on a more minor issue: how can I change the text of the prompt (currently it is Select the Select File Button...)

I tried editing s3_upload.mxml, but this didn't affect anything... obviously I have no clue about flash :)

Thanks!

Is it something as simple as

ExternalInterface.call(options.onSuccessCall, options.FileName);

at line 146 of s3_upload.mxml ?

Also, I'm curious why the code in this file seems to be calling the success callback if the user did not select any file (code around line 50)

// return if user not selected any file
if (options.FileSize == null) {
trace(options.onSuccessCall);

ExternalInterface.call(options.onSuccessCall);
return;
}

Is it possible to modify the look of swfupload? I tried editing the mxml file but no luck. I just want to be able to turn the background white? Do I need to recompile the swf?

Hey, Nick,
Yeah, you must recompile mxml file after the editing. if you are using "Flex Builder", the progress of recompile would be very easy :-)
