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

When I try to script/generate something I have to wait above 2 minutes befor I get result. Is there some way to fix this? I have Intel Core 2 Duo 6420 with 2GB RAM.

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

With code like: if @params[:pnumber] =~ /\s*p?(\d+)\s*/ if student = Student.find_first(:conditions => ["pnumber like \":pnumber%\"", {:pnumber => $1}]) @borrower = student elsif emp = Employee.find_first(:condiwions => ["pnumber like \"?\"", {:pnumber => $1}]) @borrower = emp else

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

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

Hello, I'm interested in correcting for and measuring unobserved heterogeneity ("missing variables") using R. In particular, I'm searching for a simple way to measure the amount of unobserved heterogeneity remaining in a series of increasingly complex models (adding additional variables to each new model) on the same data. I have a static database of 400,000 or

I have a loans table and a payments table. Each loan has_many payments. So far no problem. Now, the payments table has a payment_number field, and each payment has a payment_number unique within that loan. For example, Loan A can have payment_numbers 0, 1, and 2 and Loan B can have payment_numbers 0, 1, 2, and 3 (but only one of each payment_number). I can enforce this with a unique index in

Hello, this is my first post. I have a large CSV file where I need to fill in the 1st and 2nd column with a Loan # and Account name that would be found in a line of text : like this: ,,Loan #:,ML-113-07,Account Name:, Quilting Boutique,,,,,,,,,,, I would like to place the Loan #: ML-113-07 in the first column and the account name quilting boutique in the second column. If possible I would also

Hi All I found survfit function was very slow for a large dataset and I am looking for an alternative way to quickly get the predicted survival probabilities. My historical data set is a pool of loans with monthly observed default status for 24 months. I would like to fit the proportional hazard model with time varying covariate such as unemployment rates and time constant variables at loan

Hello! Given is an Excel-Sheet with actually 11,000 rows and 9 columns. I want to work with the data in R. The contents are similar to my following example. I have a list with ID-number, personal name and two kinds of loan-values. I want to aggregate the list, that for each person only one row remains and where the loan-values are added. First I tried some commands with tapply but had no

I wonder if someone out there could loan me a peek at their sip.conf? I have conflicting advice, for instance, about whether or not to use "nat=1" and also whether or not the ATA should be registering with the instance of asterisk it is going to be using to dial out. Thanks in advance. B.

Today, WINE has a distributed database of applications owned by the users of WINE. Practically, this solution is probably the only legal way to proceed unless the WINE project literally funds the purchase of every application for Windows. * Maybe, an owner of a specific program can loan the masters of their Windows programs to the WINE project with the guarantee that they'll be returned within

Hi, I am working on fitting a proportional hazard model to predict the probability of default for mortgage loans. I have a question regarding survfit function. My historical data set is a pool of loans with monthly observed default status for the next 24 months. The data is left truncated (delayed entry to observation window after the loan is opened) and right censored. I would like to

Question: When survfit() function is used upon a coxph object, the 'n' returned is vastly smaller (n=6) than the number of distinct loans in the dataset used. I am trying to estimate a Cox proportional hazards model for a set of loans (over 6000) using using time varying covariates. For this 6000+ loans, I have some 62,000 different vectors representing the loans at different periods of
