similar to: Surprise in (delete_all | clear | destroy_all) on association

Hi there I have an habtm association between 2 Models. I regularly have to truncate the table on one side of the relationship and repopulate the table with a fresh csv file. I notice that f I do Model.delete_all, none of the records in my habtm join table get deleted, whereas if I use destroy_all they do. However, the overhead of using destroy_all is too great. For the amount of records I have

Hi there I''m trying to delete a set of active record objects based on certain conditions. I''d like to do something like the following: Context.delete_all("uri IN (?)", uris) But delete_all doesn''t allow multiple arguments. Since I don''t have the IDs for the objects I want to delete, I can''t use delete(id), and have resorted to this,

I can''t see what''s wrong here but that''s probably just because I''m so new to Rails! To get right into it... I have 4 tables that look like this: Sites - id Projects - id - site_id - user_id Tasks - id - project_id - user_id Users - id The corresponding models: class Site < ARB has_many :projects, :dependent => :delete_all end class Project <

Hey I''m writing a simple admin interface thats reading user data (skills) from a comma separated file. To clear the database before inserting new skills, I use Skill.delete_all Then I insert the new values I read from a file. Everything goes well up to the point where I see that auto-generated ID''s are not starting from 1. They start off at 840 (responding to the number of

Hi all, When i use the ''delete_all'' function to remove a few rows from my database, it causes a deadlock on the sql server. The delete seems to be successful, it then redirects to the ''view'' page, and the record does appear to be deleted as far as the ''view'' rails page shows. BUT if i go into sql query analyser, i can''t do a

Sometime in the last 10 days the SVN build system (or was it the stable build system?) changed to dynamically download the soundfiles instead of including them with the downloaded code. I didn't get any prompt the the soundfiles were about to be downloaded, and to my great surprise on the next trip I made into voicemail, I now have an entirely new set of sounds on my system. I don't

Since RC2 was released, I've started re-building the music library I left behind at my previous job (all my stuff from CDs, ripped into MP3s). Recently I started an aggressive campaign of converting my CDs to vorbis files... I'm doing about 6 or 7 CDs a day at work =) Yesterday I was listening to my Talk Talk album, and noticed that on this one live track, the stereo seemed to have

I discovered the following behavior when source'ing the same file repeatedly as I edited it. My generic stopped acting like a generic. I can't tell from the docs what, if any, behavior is expected in this case. R 2.4.0 > foo <- function(object) 3 > isGeneric("foo") [1] FALSE > setMethod("foo", "matrix", function(object) 4) Creating a new

Hello, I wonder if image(t(x)[ncol(x):1, ]) can do the job correct! perhaps this does the job better: image(t(x)[,nrow(x):1]) Bj??rn From: Prof Brian Ripley <ripley_at_stats.ox.ac.uk> Date: Fri 27 Aug 2004 - 06:43:50 EST On Thu, 26 Aug 2004, Glynn, Earl wrote: > Start with: > > > x <- c(1:7,1) > > dim(x) <- c(2,4) > > x > [,1] [,2] [,3] [,4] >

When compile the following case and look at the SCEV analysis, I notice that the first two loops don't have a LoopInvariantBackedgeTakenCount (surprising) and the last one does (not surprising, except in the context of the first two examples). *void p4(int *A, int *B, long int n) {* * for (char i = 0; i < n; i++) {* * A[i + 2] = i;* * *B++ = A[i];* * }* *}* * * *void p5(int *A, int

I have to say that I was more that a bit surprised, if not to say dismayed when I booted a system with CentOS 5 installed to test a kickstart CD in interactive mode, took it to the custom partitioning screen, then rebooted without saving anything only to come up with a grub prompt, and the disk's partition table wiped. The ks.cfg file did say to wipe the disk when installing, but I would

Hello, I had been thinking for years, without having ever checked (shame on me), that indexing a named vector by a factor 'f' produced the same results as indexing it by 'as.character(f)'. I was wrong, as the following example shows: (m <- c(a=1,b=2)) (f <- factor(c(1,2),labels=c('b','a'))) m[f] m[as.character(f)] m[as.numeric(f)] When the

Some time ago someone asked for things that make R difficult to master. Here I want to record one R behavior that took me off-guard yesterday. Moral of the story: vectorialize, but don't exaggerate.
