I''m having a little trouble with understanding how to work out the schematic for some of my classes using ActiveRecord when a file is in my lib directory: Brief example: Here''s the outline of the files in use: ....app ........controllers ............application_controller.rb ............rushing_offenses_controller.rb ........models ............rushing_offense.rb ....lib

Example model: demo --app ----Controllers ------application_controler.rb ------demos_controller.rb ----Models ------demo.rb ----Views ------demos --------index.html.erb (I want to keep this) --------edit.html.erb (delete) --------new.html.erb (delete) --------show.html.erb (delete) http://localhost:3000/demos/new (should not be a route) http://localhost:3000/demos/edit (should not be a route)

I just have a few questions about join tables. From my understanding the following applies (correct me if I''m wrong): 1.Join tables are always named with the names of the two associated tables, in alphabetical order, separated by an underscore. 2.The foreign key fields are named with the name of the table they are referencing, with _id appended. 3.The foreign key is referencing a

First, my site will be down December 27-28 because of a network upgrade at Penn. It will also be down at least one day before that, while I upgrade the operating system. (And another day some time in January because of a planned power outage.) Second, I have replaced the search engine in my R site: http://finzi.psych.upenn.edu/ I am now using Namazu instead of HtDig. The direct link to the

Inspired by the functions that Barry Rawlingson and Dave Forrest posted for searching Rwiki and R-help archive, I've made up a function that does the search on Prof. Baron's site (Thanks to Prof. Baron's help on setting up the query string!): RSiteSearch <- function(string, restrict="Rhelp", format="long", sortby="score",

Hello all, I''m trying to get some records in my application to sort based on a SQL calculated value and am getting no records returned. I have checked and double checked and the query that TS is indexing is working out, but the problem is with the controller. Here is what I''m indexing: ---------------------------------------------------------- indexes

Ok, I''m sure this has to be something stupid that I''m doing (or not doing), but I can''t seem to get things to order by the specified column. class List < ActiveRecord::Base has_many :list_items, :order => "orderby" The error I get back when trying to save the link is: Unknown column ''position'' in ''order clause'':

I have a question regarding?the very useful doBy package, and specifically, the transformBy() function?with the lag() and diff() functions. ?It is often useful to lag or difference data within a panel, i.e., within a by-group. ?Is the following code a safe use of transformBy? Is there an alternative? First, does the initial "orderBy" statement guarantee that the Time order will be

I have to build an array through both activerecord and also through a ferret index. I was hoping to find a way of sorting the array as i combine the two so def advanced_search(search_text, store, format, sortby) # find items in ferret index items = Item.find_by_contents(search_text) # and now find all the items from a certain store or category items_from_sql = Item.find_by_sql("SELECT *

Dear R users, I have the following data frame: PROCHI date_admission 2 CAO0000713 1999-12-11 4 CAO0000713 1999-10-25 21 CAO0001743 1989-05-04 25 CAO0001743 1996-09-12 26 CAO0001743 1989-05-17 27 CAO0001743 1987-09-17 28 CAO0001743 1987-09-19 29 CAO0001743 1988-01-27 36 CAO0001747 2004-03-21 38 CAO0001747 2004-03-22 39

Dear Ruser's I want to substitute each "NA" by the group mean of which the "NA" is belonging to. For example, substitute the first record of traits "NA" by the mean of "BSPy01-10" in the dummy dataframe. I have ever tried to solve this problem by using doBy package. But, I failed. I ask for the advice on how to use "lapplyBy" function of

I know there are a lot of reshape questions on the mailing list, but I haven't been able to find an answer to this particular issue. I am trying to get a datafame structured like this: > sub <- rep(1:5) > ta1 <- rep(1,5) > ta2 <- rep(2,5) > tb1<- rep(3,5) > tb2 <- rep(4,5) > DF <- data.frame(sub,ta1,ta2,tb1,tb2) > DF sub ta1 ta2 tb1 tb2 1

I need to find out how I can create and save a large dataset to a table based on multiple returned arrays from a Rake task. Here is my example using just two arrays (there are 14 in this particular rake task): update_tsos_offense = TsosOffense.new to_team_id, to_ppcs = update_tsos_offense.calculate_tsos(TotalOffense, "ydspgm", "desc") ro_team_id, ro_ppcs =

Dear Ruser's I ask for helps on how to substitute missing values (NAs) by mean of the group it is belonging to. my dummy dataframe is: > df group traits 1 BSPy01-10 NA 2 BSPy01-10 7.3 3 BSPy01-10 7.3 4 BSPy01-11 5.3 5 BSPy01-11 5.4 6 BSPy01-11 5.6 7 BSPy01-11 NA 8 BSPy01-11 NA 9 BSPy01-11 4.8 10 BSPy01-12 8.1 11 BSPy01-12 6.0 12

Hi Folks, After loading a data set, I run the following: > kSum <- orderBy(~group,(summaryBy(DP_Level~F2 +group,data=kdata,FUN=c(mean,sd),na.rm=T))) kSum looks like this: > kSum F2 group DP_Level.mean DP_Level.sd 1 1.0 N -1.55186475 11.022245 4 2.0 N -2.48013300 10.624583 7 3.0 N -12.47671250 11.104792 10 4.0 N -13.72430950 12.000779 13

I''m trying to sort an object by its property names. As I understand it, iterating over an object using for...in or using Hash.each() (or Hash.sortBy()) does not guarantee the order of the properties. Is there an easy and low-overhead way to guarantee order? Or would I need to have some type of collection object that uses arrays instead of the property-value configuration that Hash

Neither we have them now. Unfortunately disabling the test in the 3.2 branch won't fix the problem, and the actual fix may require cherry-picking a number of recent CLs, which may be rather intrusive.
