What is the rails idiom for submit buttons on forms? All other field types have helpers, but button_to creates its own form, so should not be used. I''ve looked in "Agile Web Dev. with Rails" but can''t see what I should do instead. Is this "difficult" because it runs counter to AJAX type forms? And, related, is there a way to ensure that hitting return in

Agile Web Development with Rails doesn''t seem to have NULL in the index [or my eyes have failed me again], and web searching turns up lots of SQL statements containing NOT NULL. I have a table of loans, and I want to record when something was loaned and returned. The loan date can''t be null, or there''d be no entry in the table. The return date must be something

I keep an old Windows machine around for making sure that RedCloth Win32 binary gems install. When I try gem update RedCloth, it just installs 4.1.9. Did I do something wrong in the gemspec? Would someone else with a windows machine try it and let me know how it goes? Jason

Is find_all_by deprecated and/or find_first_by for 2.0.2? If not, what is actually deprecated? just find_all(..) and find_first()?

Hello list, I'm following the paper (http://www.jstatsoft.org/v27/i02/paper) on how to use "plm" to run panel regressions, and am having trouble with what I believe should be something very basic. When I run the command (p.9 in the paper): R> dynformula(emp~wage+capital,log=list(capital=FALSE,TRUE),lag=list(emp=2,c(2,3)),diff=list(FALSE,capital=TRUE)) I see: emp ~ wage +

Hi All, I am using R 2.11.0 on a Ubuntu machine. I have a time series data set and want to run rolling regressions with it. Any suggestions would be useful. Here are the details: (1) I convert relevant variables into time series objects and compute first differences: vad <- ts(data$ALLGVA/data$GDPDEF, start=1948, frequency=1) emp <- ts(data$ALLEMP, start=1948, frequency=1) vad.dif1 <-

Native ERB in ruby, and eruby, seem to lack the -%> feature for suppressing trailing newlines. Thus erb -n script gives errors. Where is Rails ERB so I can invoke it directly? Thank you Hugh

Hi, I have been playing around with Ruby after reading so much about it, and so I started tweaking with auto generated scaffold. But it seems like I must be missing something, can someone else please help me take a look and give me a couple pointers? In short I was trying to make a class User that has a method addupdate with 2 parameters (alias and email) which would either update the

Who really uses strikethroughs?? This is one of the most common tripwires in RedCloth. You are the friend--the only friend--who has offered to help. Obviously em dashes. I died in -2006- wait, no, two-thousand-FIVE! Obviously strikethrough. I''m going on a trip - a long one - to the Virgin Islands. That''s got to be en dashes. Such a cheap, no-hassle, no-worry

I have been using R off an on for approximately 3 months. As such, I am not very knowledgeable about coding in R. Currently I am running into the following problem. I'm using scan to make data available in R. The data I'm loading consists of over 400,000 records with 5 data fields. After running the following statement: mod1<-glm(DefMigFlag~MaxFICO,

I've taken ~1000 samples from 8 biological replicates, and I want to somehow combine the density functions of the replicates. Currently, I can plot the density function for each biological replicate, and I'd like to see how pool of replicates compares to a simulation I conducted

Dear R-help I am wondering if somebody wrote some code to convert an adjacency list model into a nested set model.

I create my rails app, with modifications to the default from a script. Having had to upgrade rails once, and knowing that this is likely to happen again because of the rapid updating of rails, it seems the most sensible way to do it. As a result, I often do /bin/rm -rf csestore and then run my script from another window to repopulate it. So naturally, to save having to cd into csestore, and

I have a data set covering a large number of cities with values for characteristics such as land area, population, and employment. The problem I have is that some cities lack observations for some of the characteristics and I'd like a quick way to determine which cities have missing data. For example:

I have been trying to model a labeled graph using ActiveRecord (trunk version). Basically, I have a ''Node'' model which represents a node linking to other nodes. Links (aka edges) are labeled (i.e., have a ''label'' attribute and other behavior). Thus I decided to model edges as an ''Edge'' model and use a ''has_many :trough''
