...emoting made easy" (http://sean.treadway.info/). I''m saving a file to the filesystem, and then trying to put it in to the database when I do the final submit with ajax. I thought picking the file up and putting it in the db would be as easy as having: "@image.data = IO.read("path_to_file") in the create method in the controller. But I get: "undefined method `read'' for #" What''s the right way of doing this? - Henrik

Hi, im getting a little trouble with this, im using TinyFile as the example to upload files http://wiki.rubyonrails.com/rails/pages/TinyFile/versions/20 All goes well but the files uploaded are saved with permissions 600 (linux) and in the case of images arent showed on the browser(but uploaded and stored in the server without problems) i have to manually ftp to the uploaded files folder and

...;ve also tried putting "File.umask(022)'' inside environment.rb but that doesn''t make a difference. To handle uploads, I have a resource model which does the following in the before_create filter: def before_create return FileUtils.copy( @uploaded_file.local_path, self.path_to_file) if @uploaded_file.instance_of?(Tempfile) # else File.open(self.path_to_file, "w") { |f| f.write(@uploaded_file.read) } end If anyone has any other hints for how to change the umask, please let me know, this is driving me crazy! Thanks, Mike

Where should I look for information on how to use Rails and Ruby to accept the upload of a file and then to save that file to the file system of my server? I''m reading the "Uploading a file" section of Agile Web Dev with Rails, but it''s geared toward saving the file in the database. Any advice? Thanks, Jeff -- Posted via http://www.ruby-forum.com/.

The domU is using pygrub to boot its own 2.6.18.8-xen kernel. It can be booted successfully under 2.6.18.8-xen dom0 and xen 3.3.1. However when upgrade dom0 to 2.6.32.15 and xen 4.0.1-rc3-pre, the domU can not boot with tapdisk. I am wondering it is something related to the blktap driver. *When using tap:aio:* PATH/disk.img in domU disk configuration, the boot process hanged at a prompt: XENBUS:

From some old May 2017 email. I asked the following: "From the docs, I see you can identify the shards by the GFID # getfattr -d -m. -e hex/path_to_file/ # ls /bricks/*/.shard -lh | grep /GFID Is there a gluster tool/script that will recreate the file? or can you just sort them sort them properly and then simply cat/copy+ them back together? cat shardGFID.1 .. shardGFID.X > thefile " / The response from RedHat was: "Yes, this sh...

I have a regular plain old static HTML file under my RAILS_ROOT that I would like to serve as itself (without any dynamic anything). How can I write a route to "pass the request through" succesfully. I tried map.connect ''path_to_file'', :controller => nil, :action => nil, :id => nil but that didn''t work. Also, note that I have this route already configured: map.connect '''', :controller => "eSimply" so I''m thinking that maybe that picks up everything? Thank...

Hi all, After a short hiatus away from R I have found that it's changed a bit. I used to keep a definition of .First in .Rprofile that did a couple of things on startup (load a couple of libraries). Now, I've discovered that when I change the definition of .First in .Rprofile it doesn't change anything when I start up, because .First is held over in .Rdata from the last session.

Hi, all. I'd like to print out a table to a file (I'm using cat(...,file="foobar")). the problem is, cat doesn't print out the headings for the table (making the table hard to interpret!). For example: > table(showdistribution(nw.109.transitions, interruptions[1])) interruption opened-map 1 2 >

I have problems with very large numbers using knitr. In the following, my a and b are extremely small and ssrr and ssru are extremely large. Knitr delivers error messages. Scaling ssrr and ssru by 1000 resolved the problem: ssrr <-ssrr/1000 ; ssru<-ssru/1000 Any clue as to how I might resolve the problem? BTW, the same program does run in another computer. I am wondering whether my

Hello, So I have a volume on a gluster install (3.12.5) on which sharding was enabled at some point recently. (Don't know how it happened, it may have been an accidental run of an old script.) So it has been happily sharding behind our backs and it shouldn't have. I'd like to turn sharding off and reverse the files back to normal. Some of these are sparse files, so I need to account
