The following line works OK:- @todos = Todo.find(:all, :include => [ :whens],:order => "position ASC") The following line is mysteriously deleteing :where rows from the DB after

dear members, I have a function ygrpc which acts on the daily price increments of a stock. It returns the following values: ygrpc(PFC.NS,"h") [1] 2.149997 1.875000 0.750000 0.349991 2.100006 0.199997 4.000000 2.574996 0.500000 0.349999 1.500000 0.700001 [13] 0.500000 1.300003 0.449997 2.800003 2.724998 66.150002 0.550003 0.050003 1.224991 4.899994 1.375000

Hi Akshay, (Please include r-help when replying) You have learned that PFC.NS and snl[[159]] are not identical. Now you have to figure out why they differ. This could also point to a bug or a logic error in your program. Figuring out how two objects differ can be a bit tricky, but with experience it becomes easier. (Some others may even have some suggestions for good ways to do it.) Basically

Hi! I have some trouble with userdb, ldap an extrafields for acl_groups. There is a script in python, which fetches the groups and sets the environment-variable ACL_GROUPS to this groups. It works when i log in to imap (thunderbird for example shows my? public folders which are protected by acl_groups). But when it try doveadm mailbox list -u user.name the mailboxes are not listed and with

Well, you don't have postlogin scripts when running doveadm. Those are executed by *-login and usually execute the actual protocol handler.

Hi, I have a situation I''m hoping someone out there may be able to shed some light on. I have a Rails app (2.1.0 on Ruby 1.8.7) with a wizard-based sign up process, that has recently been changed from storing incremental data in the database to having a medium sized object graph living in the user session until the user completes the entire sign up process (this is a business

When I''m executing cucumber tests, I noticed that sometimes rails app (in test env.) getting several the same requests (GET or POST) usually around 3, and it doesn''t render anything with empty HTTP status code. Have anyone met something similar to that issue? here is some example of log file: Started POST "/account" for 127.0.0.1 at 2010-11-30 22:34:17 +0200

I''m getting a strange error in the production.log (I''m on a TxD shared server). The first entry is a successful request from right after restarting lighttpd and killing all the procs, the second is the error after accessing the site half an hour later without having changed anything. Restarting lighttpd resolves the issue. What might be going on?

Hi R users, I am trying to omit rows of data based on partial matches an example of my data (seal_dist) is below: A quick break down of my coding and why I need to answer this - I am dealing with a colony of seals where for example A1 is a female with pup and A1.1 is that female's pup, the important part of the data here is DIST which tells the distance between one seal (ID) and another

Dear R gurus, I am interested in permutations-based cpu-intensive methods so I had to pay a little attention to Random Number Generators (RNG). For my needs, RNGs have to: 1) be fast. I profiled my algorithms, and for some the bottleneck was the RNG. 2) be scalable. Meaning that I want the RNG to remain fast as I add threads. 3) offer a long cycle length. Some basic generators have a

Hi All, I am trying to run a loop that will have varying numbers of rows with each output. Previously I have had the same number of rows so I would use (and I appreciate that this will no doubt achieve some gasps as being thoroughly inefficient!): xdfrow<-(0) xdfrow1<-(1:32) xdfrow2<-(33:64) xdfrow3<-(65:96) xdfrow4<-(97:128) xdfrow5<-(129:160) xdfrow6<-(161:192)
