similar to: Basic Q: Please help with iterating through an AR.find result

I am working on a site that has Forums. There are two tables that track the users on this site. One table ''Users'' is basically the table for the salted_authentication generator. The next table, ''ForumMember'' tracks each user''s status in each forum. ForumMember contains a foreign key to Forum, and to User. I have a main page in which I list all the

I started a php-based website a few months ago with a buddy of mine on netfirms.com. I was perusing their knowledge base and I came upon a quick-start for something called Ruby on Rails. Since then I have immersed myself in RoR. I''ve done the tutorials, I''ve purchased the books. But, I could never get even a sample RoR app to work on netfirms. 500 server errors.

The is something I wrestle with a bit when I construct joined queries.. Perhaps some experienced insight will straighten this out for me. Say you have two tables with two models, ''authors'' and ''posts''. an author has_many posts, a post has_one author. You need methods to do the following queries: find_author(postid) find_posts(authorid) And you are doing a

I started three new threads recently, "Feature proposal: differential pools" "Feature proposal: trashcan via auto-snapshot with every txg commit" "Flushing synchronous writes to mirrors" Matthew Ahrens and Henk Langeveld both replied to my first thread by sending their messages to both me and to zfs-discuss at opensolaris.org, and Matt did likewise for my second

Hi, I'm having trouble compiling R-2.10.0 (R-patched_2009-11-02.tar.gz) on solaris 10 and am hoping for some advice. I'm getting errors about having the wrong version of lib_I_dbg_gen.so.1 ("version `DBG_GEN_5.1' not found"), when it gets to the step of compiling recommended packages (cluster). I think we do have the right version of lib_I_dbg_gen.so.1 on the

Hi all, The link contains a stingy article on AJAX and other somewhat browser dependant stuff. http://techrepublic.com.com/5254-6257-0.html?forumID=99&threadID=184332&messageID=1963135&id=2926438 Being a webdev myself and also a diehard perfectionist, I could relate to some of it. Let me state that the article does NOT represent my opinion, nor is it to fire up a discussion!! It

Hi all, Being the glutton for self-inflicted punishment that I am, I did a clean install of F9 yesterday. :-) As it relates to R: 1. Building R from SVN: R version 2.7.0 Patched (2008-05-12 r45683) It builds and passes make check all without issue. F9 is using: gcc (GCC) 4.3.0 20080428 (Red Hat 4.3.0-8) 2. As was noted with F8, the lack of the Java-JavaScript bridge in the default

Greetings. This is very basic but we can't figure it out. The following simple code counts how many values land in the "tail" (below a quantile) of a standardized normal distribution of random numbers. First two commands are inputs: > c <-0.05 > i <-2500 Second two commands are formulas I want to repeat many times (sort of like an Excel/VBA macro) using those same

Hello all, I would like how to modelized a time serie with AR-ARCH process. It can be used arma and garch functions in tseries package for build ar process or a garch process, but how can it be modelized a ar-garch model ? Thanks [[alternative HTML version deleted]]

Hi, Let theta be the coefficient in AR(1) model, the components of the correlation structure is equal to 1 for times s = t, and theta^|t-s| for t > s. Could someone do me a favour to give some ideas on the correlation structure in AR(2) model and correlation structure of ARMA(p,q), as well? Thank you Fir [[alternative HTML version deleted]]

Sorry to trouble the list with another Dreamhost problem, but looking through the archives I see nothing that can solve my problem. I have installed my app as per http://wiki.dreamhost.com/index.php/Ruby_on_Rails#Quick_Start_Guide_August_2006 with a symbolic link from my_domain.tld in ~/ to ~/apps/residence/public/ I get the Rails welcome screen. I have uploaded my app directory etc, and

Hello~~~ I need to use some functions provided by xen, such as xc_vcpu_getcontext(), xc_map_foreign_ranger() and so on. I have find them in the /libxc/xc_domain.c~~~ But I don't know how to use them in my program. For example, if I need to use the function named printf(), I have to include the header file <stdio.h>~~~ Now, I want to use these functions provided by xen, which header

Suppose we have a method ''foo'' which internally uses another method ''bar''. Being good BDDers we mock out the ''bar'' method. After all, we only want to spec the ''foo'' method - actually running the ''bar'' method means slower, less maintainable and brittler specs. That''s why we <3 mocking,

I''ve been wrestling with this all night, I''m hoping someone can help. I followed the exact steps in: http://wiki.rubyonrails.org/rails/pages/HowtoUseRailsWithSubversion ..but when I open a new ''Checkout project from SVN'' in RadRails, it opens up the second level dirs as the project dirs (ie. app, log, script, etc), leaving me with a mess of projects. I redid

Standard behavior for the list action is to use content_columns to get all the fields of a model and then do something with them. I''d like to ignore some of them and iteratre over the rest. For instance I may have A B C D ... X Y Z and I''d like to do something special with A and B and then Y and Z, but in the middle I''d definitely like a loop to say
