I can''t see how to use variables so I am using console to test things out... clients table - a column named first_name My very brief console session... >> clients = Client.find_by_sql("select * from clients where first_name = FN") ActiveRecord::StatementInvalid: RuntimeError: ERROR C42703 Mcolumn "fn" does not exist Fparse_expr.c L1034

I am struggling to understand the methodology here... I have a find.rhtml <%= start_form_tag :action => ''list2'', :first_name = client %> <%# render :partial => ''form'' %> <p><label for="client_first_name">First name</label><br/> <%= text_field ''client'', ''first_name''

I tried to use ''rake db_schema_dump'' from old MySQL database and then use ''rake db_schema_import'' to rebuild the database in PostgreSQL. The issue here is that only some of tables can be imported successfully. For example, in the dumped schema.rb: create_table "profiles", :force => true do |t| t.column "ticker", :string, :limit

Hi everyone, I''ve been playing around with the Globalize plugin for some days now but I can''t seem to make it work properly with my models. I''m currently using Postgres 8.0 for the database and needed to make some modifications with my migration file that was posted by Jake Morrison in the Globalize wiki...

Hello list, have a problem with sieve script. I want to perform an action if an arbitrary headerline contains a defined string. I tried with regex: if header :regex [".*"] ["searchstri.*"] { fileinto "junk"; } This is not working because regex is only used in 2nd argument ["searchstri.*"] In 1st argument [".*"] no regex is used, sieve

I recently posted a request for a Mozilla search engine plugin for the R java search applet. Having recieved no response, I pursued this myself and came up with an alternative. I found a "bookmarklet" that was used to submit searches to Amazon. I modified the code to submit searches to the R search engine. I tested the following using Firefox 0.9 on Windows 2000. Create a

Hi, please excuse my poor englisch. Is it possible to connect a (privat Test-Asterisk) to my privat ISDN and allow him to only answer one dialed number? We have 3 up to 10 Numbers on each (Euro-)ISDN (2 b-chanels), it cant't be done by the last Digits cause the numbers are completely different. For Example: I have 3 Numbers (641717, 928752....) Is it possible to tell Asterisk (in

Hi, I really need help with making the ''searches_on :all'' in Duane Johnson''s TextSearch work with MySQL (not sure if it works with other db''s). http://wiki.rubyonrails.com/rails/pages/TextSearch I realize that there are other search packages out there. But this particular solution best fits my small needs of searching a small database. I''ve gotten

If you've 'rediscovered the web' with Firefox (http://getfirefox.com), you might find this tip handy. Suppose you want to search the (local) R documentation for information about the lme function. Wouldn't it be nice to just type into the browser address bar: r lme and have the search performed? Here's how (on Windows): Click on this link:

I''m trying to get some opinions on a design I''m floating ("rails way" or not?). Say I''ve got an Author model in my Blog application and I want my administrators to be able to disable authors. I don''t want to delete authors because this would cause data integrity issues (orphaned Author foreign key in the Post model). So my plan is to re- task the

Hi, We are using samba version 3.0.28 on Sun solaris 5.10 integrated with Windows 2003 Domain Controller. It has been running for couple of years without any issues. Recently the 2003 domain controllers are upgraded to 2008 R2 domain Controllers and the samba server that we currently have is not authenticating With the new domain controllers. Could you please let me know which version of Samba

Dear R users, A co-worker and I are writing a function to facilitate graph plotting in R. The function makes use of a lot of lists in its defaults. However, we discovered that R does not necessarily preserve the defaults if we were to input them in the form of list() when initializing the function. For example, if you feed the function codes below into R: myfunction=function( list1=list

I everyone, i have a little problem with tklistbox,the " " character and Rcmdr. Please look at this code require(tcltk) tt<-tktoplevel() levels.list2 <-tklistbox(tt,selectmode="multiple",exportselection="FALSE", height=4, yscrollcommand=function(...)tkset(levels.list2.scroll,...))

Hi, Algorithm question: I have two sets of "intervals", where an interval is an ordered pair [a,b] of two numbers. Is there an efficient way in R to generate the intersection of two lists of same? For concreteness: I'm representing a set of intervals with a data.frame: > list1 = as.data.frame(list(open=c(1,5), close=c(2,10))) > list1 open close 1 1 2 2 5

Hi, I have 2 questions on list object:   1. Suppose I have a matrix like: dat <- matrix(1:9,3)   Now I want to replicate this entire matrix 3 times and put entire result in a list object. Means, if "res" is the resulting list then I should have:   res[[1]]=dat, res[[2]]=dat, res[[3]]=dat   How can I do that in the easilest manner?   2. Suppose I have 2 list objects: list1 <- list2

hi, i'm trying to figure out if there's any possibility to write a whole vector into a matrix or data.frame or something like that. i don't mean transormation. Here an example: [,1] [,2] [1,] "a" "d" [2,] "b" "e" [3,] "c" "f" where e.g. a is a<-c(0,1) vector of length 2, b a vector of length 4,... (i know that

Hi R users I was wondering on how to use lapply & co when the applied function has a conditional statement and the output is a 'growing' object. See example below: list1 <- list('A','B','C') list2 <- c() myfun <- function(x,list2) { one_elem <- x cat('one_elem= ', one_elem, '\n') random <- sample(1:2,1) show(random)

to the ones i defined in my model? for example if in the model i specify acts_as_ferret to index only column 1, 2, and 3 in my table....how can i perform a search just for column 1 if need be. for example, id like to give the user the ability to just search on title name vs description, etc... thanks! -- Posted via http://www.ruby-forum.com/.

Hi, This has bugged me for a bit. First question is how to keep classes with rbind, and second question is how to properly return vecotrs instead of lists after turning an rbind of lists into a data.frame list1=list(a=2, b=as.Date("20090102", format="%Y%m%d")) list2=list(a=2, b=as.Date("20090102", format="%Y%m%d")) rbind(list1, list2) #this loses the
