How do you run an ad-hoc query that does not belong in any model? I thought it was something like ActiveRecord::connection.find("my query..."), but I can''t seem to find the documentation on it. I know I''ve seen it somewhere before, though. thanks, Jeff -- Posted via http://www.ruby-forum.com/.

Hi, I''d like to do a "find_by_sql" without a model (e.g. <model name>.find_by_sql("...")) as the results I get back are a once off special, and I''m happy to handle them as an array. How do I do this? "ActiveRecord::Base.find_by_sql(...)" does not seem to work? Background - At the moment I''m doing within a model <model_name>,

Hello, Is there a way to get a single TRUE or FALSE statement from comparing two vectors? For example, c(1,2,3) == c(1,2,3) produces TRUE TRUE TRUE where I would like it to produce only TRUE for use in an if statement. Likewise, when two vectors are not exactly identical (in all elements) I would like a single FALSE result, as opposed to c(1,2,3) == c(1,2,5) TRUE TRUE FALSE Any ideas?

I was thinking about having instance variable stored and fetched from session container automatically before calling an action and after the action is finished. Using methodology of accessors it would look like: class MyController < ActionController::Base persistent_attr :person def alfa person = ''John Smith'' # render as usual view alfa.rhtml with anchor

I am trying to do a tutorial improvement on the wiki but I am having some problems with the auto formatting. Using httdp.conf produces http://httpd.conf when filtered. Using *.so produces .so and bold text there after. Is there any shorthand for the user for making text appear as it should without the linking and re-writes? Or does the admin have to change the filters in Instiki? Tesla

Hello, I'm running a very long for loop that usually takes hours. For my own piece of mind, it would be nice if I could check periodically and see which iteration the loop is on. A line of code that told R to print the iteration number every 100 or 200 iterations would be perfect. Does anyone know something like this? I've never known how to print anything within a for loop before the

Thanks, but this is most probably different issue. My maildirsize is computed incorrectly even if I delete it completely and let dovead recompute it so expunging is not in the game. Is there any way how to track/debug the recomputation algorithm in dovecot? On Wed, Aug 24, 2016 at 12:02 AM, WJCarpenter <bill-dovecot at carpenter.org> wrote: > A long shot, but here's how I

Hi, Rsync is still hanging under cygwin for me. I'm using rsync 2.6.0 and i've tried cygwin-1.5.6-1 as well as a snapshot of 1.5.7. I've noticed that some people are having success. I shouldn't have to do anything interesting in order to make this work, right? *********************************************************************** This message is intended only for the use of

Hello, I'd like to plot an empirical cumulative distribution function, except instead of the fraction of values < x, I'd like the fraction of values > x. I think this can be done using the ecdf function in {Hmisc}. I installed the package and loaded it. However, when following the example given in the documentation, I get an error: x <- rnorm(100) ecdf(x,what='1-F')

Hello, I created an array to hold the results of a series of simulations I'm running: d.eta <- array(0,dim=c(3,3,200)) <simulation goes here and populates the array but it's not important> Then I tried to save the results using this: save(d.eta,file="D:/Simulation Results/sim 9-23-11 deta") When I later tried to reload them using this: d.eta <-

Hi, One of my email accounts has 1,5gb of emails in INBOX, but maildirsize shows only 528mb. 'du' also shows 1,5gb and there are 3809 files in cur directory.

I have a model, message, which has text and a user (do not need to worry about associating users to messages right now). These messages come in and I would like to create a response for each, which itself is a message. Then I would like to create a transaction paring these
