fileserver
2+
=============
3+
4+
Simple handling of multi-part form data from file-uploader framwork.
5+
Uses webmachine so assumes som familiarity with that.
6+
7+
You probably want to do one of a couple of things at this point:
8+
9+
0. Get the latest build of file-uploader and place in the right
10+
directories under priv/www/static/.
11+
e.g. place file fineuploader-{VERSION}.js in priv/www/static/js/.
12+
13+
1. Update priv/www/static/html/index.html to reflect correct version files
14+
15+
2. Get dependencies and Build the application:
16+
$ ./rebar get-deps
17+
$ ./rebar compile
18+
19+
3. Start up the application:
20+
$ ./start.sh
21+
22+
4. Upload some files
23+
localhost:8000
24+
25+
26+
### Notes
27+
28+
0. Currently all files are saved to /tmp to change this edit the
29+
despatch.conf file ( look for '/tmp' ).
30+
31+
1. You will have to edit the fineuploader-{VERSION}.css file so that
32+
the image paths are relative. i.e. background: url("../img/loading.gif"), etc.
