Hi, I''m having a weird validation issue. Validation isn''t working for certain attributes and, for some reason, it''s also affecting things outside of validation. For campers on certain camp types, we require some information about their school. I tried to validate the information this way: validates_presence_of :school_type, :if => Proc.new { |c| !c.booking.nil?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The lmer() function in the lme4 package has some code of the form mc <- match.call() mc[[1]] <- as.name("lFormula") lmod <- eval(mc, parent.frame(1L)) this is a fairly common idiom in R, found e.g. in lm(), used when one wants to pass all of the arguments of a function to a different function (in the case of lm() it's

Hello, I need to be able to write a temporary file for use during the request only. Locally I can use the following successfully: tempfile = File.open(a.original_filename,''w'') tempfile.write_nonblock(a.body) paperclip stuff........ tempfile.close That works great, but not on Heroku... How can I do the above with Heroku''s restrictions:

I'm used to Debian-based distros which have a tempfile(1) utility for safely and sanely creating temporary files. There isn't a comperable utility for RHEL/CentOS systems. I've been exercising Google-fu looking for a good robust tempfile generation idiom, but haven't turned one up yet. Hence this appeal to the lazyweb. -- Dr. Ed Morbius, Chief Scientist / | Robot

I have three (out of 90) machines with the error: cannot generate tempfile `/tmp/puppet.30616.9'' I have plenty of disk and plenty of inodes. My temp directory is permissioned: drwxrwxrwt 4 root root 20480 2012-05-24 01:33 /tmp I get these for two puppet items on each row. The daemon is not running. I run it manually using /usr/sbin/puppetd --verbose --no-daemonize --onetime

Hi all, Yesterday, I had some problems reading JPG files in my tests. Turns out the problem was that Windows Ruby doesn't set it's Tempfile to work in binary mode. Since I deploy on Linux, that has never been a big problem, but now I'm working on some software that works with binary files exclusively. Anyway, I am making this fix available as a Rails plugin. The details can be

G'day all, The documentation for tempfile states : "The names are very likely to be unique among calls to tempfile in an R session and across simultaneous R sessions. The filenames are guaranteed not to be currently in use." My problem I think relates to the second part of the sentence, which is the guarantee... and it is being met ... but I need to save the files as .png files,

Dear List: I'm posting this to provide a possible solution and to document to what appears to be an R limitation. The solution is more of a cheap hack that works for now. To provide a little background, I am looping through a dataframe and creating Sweave documents using data from each row in the dataframe. It appears that this technique is not scalable to large dataframes without making some

I''ve been facing a problem when generating a model (or controller, ...). I''m using rails 2.3.8 and ruby 1.8.7. Has anybody been facing anything like this? script/generate controller test /usr/lib/ruby/1.8/tempfile.rb:12: superclass mismatch for class Tempfile (TypeError) from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require''

I am looking for a way to upload a file to Rails 3 app, but without generating a temp file. Googling the issue gave me some insight in how the file upload works. As I understand Rails creates a temp file when the file size is larger than 20kb. Is there a way to change this limit and avoid the temp file generation? Another solution I was looking in was creating a Rack App and so avoid the file

I'm curious how to go about submitting a suggestion that affects both the original BSD version and the portable release. A few days ago I sent off a BSD-relative patch to openssh at openssh.com. Is this the right thing to do? I didn't hear anything back, but it's only been 3 days, so I'm probably just being too antsy. In the meantime, maybe someone else out there would like to

The other day I was working on an example which used tempfile() to create file for use by the graphics device. And while I love tempfile()---as it is portable and clever and the files get cleaned by R and all that---I noticed one missing feature I would like to see: beside a starting name pattern, and an optional directory, an 'file extension' argument would be nice to have. As e.g. in

Dear List: I am encountering an error that I can't resolve. I'm looping through rows of a dataframe to generate individual tex files using Sweave. At random points along the way, I encounter the following error Error in file() : cannot find unused tempfile name At which point Sweave halts. There isn't a logical pattern that I can identify in terms of why the program stops at

Hi, just a simple question between error_message_on / error_messages_for ... Well, if you use error_messages_for in your web page, there is no problem even if anObject==nil (for example , the first time you load your form) whereas error_message_on must be use with an instanciated object ... So, you always has to double check if anObject is not nil before using error_message_on ? I

Hi all, previously I submitted this thread through Nabble which seems fail therefore sending it again.... suppose I have written following function :  > fn = function(x) return(x+x^2)  > fn  function(x) return(x+x^2)  Here you see, if I type only the function name all inside information of this function are visible. Is there any way to protect them i.e. make them invisible?  Thanks
