similar to: validates_format_of :url, regexp?

Railsters: ActiveRecord''s validation system puts other database systems to shame. However, the newbies might not know how to write a regexp that excludes a match, instead of tests for it. Understand - I''m just asking this question to help them. I have been using Regexps since ''grep'' on Xenix! But the newbies here might not know how to do this:

Hi, This is my code (my data is attached): library(languageR) library(rms) library(party) OLDDATA <- read.csv("/Users/Abigail/Documents/OldData250412.csv") OLDDATA$YD <- factor(OLDDATA$YD, label=c("Yes", "No"))? OLDDATA$ND <- factor(OLDDATA$ND, label=c("Yes", "No"))? attach(OLDDATA) defaults <- cbind(YD, ND) set.seed(47) data.controls

Hi, I am looking at the effects of two explanatory variables on chlorophyll. The data are an annual time-series (so are autocorrelated) and the relationships are non-linear. I want to account for autocorrelation in my model. The model I am trying to use is this: Library(mgcv) gam1 <-gam(Chl~s(wintersecchi)+s(SST),family=gaussian, na.action=na.omit, correlation=corAR1(form =~

Dear List, I have very little experience with lists and am having some very basic problems. I don't know how to add columns to the lower levels of a list, or how to take something from the upper level and add it as a column to the lower level. I am analyzing animal movement data in the package Adehabitat. I have a list of animal movements called "cut.ltr" (class ltraj) that have

Hi all, I recently noticed something really weird in url_for results let''s say that we have something like this somewhere in code <pre> URL1:<%=url_for( {:action=>''foobar''}.merge({''action''=>''ohmy''}) )%> URL2:<%=url_for(

In a model I have following validates_format_of. Is there an easy way to DRY this up? It seems to be rather repetitive. validates_format_of :expiration_date, :with => /^[0-9]{4}[-][0-9]{2}[-][0-9]{2}$/ validates_format_of :activation_date, :with => /^[0-9]{4}[-][0-9]{2}[-][0-9]{2}$/ validates_format_of :some_other_date, :with =>

I need a validates_format_of that disallow dots. In the api there is nothing to find about how validates_format_of exatly works. Is there a better documentation or is there something that can tell me howto disallow dots. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups

Hi all, I''ve got a form which accepts a "price" field and I''m attempting to validate it and allow some flexibility in the way the user enters it. It''s a numeric field but I want the user to be able to enter dollar signs and commas naturally in the data entry. I''m trying to understand how to use validates_format_of, and I''m not sure what

Hi all, I''m hoping to stir the Rails pot a little bit here, so please go easy with me ;-) Regular Expressions is the most densely inhumane language construct ever invented in any ''civilisation'', and the fact that we still have to dirty our minds with this in Rails is something that (sh/c)ould ideally be corrected in Rails (preferably before the release of 1.2

I''m using validates_format_of and the validation I want to do works, but I can''t get an error message to be displayed if the data is invalid: validates_format_of :mobile, :with => /\A[\+0-9]+\Z/, :message => " - Wrong" I have another validation some where else that does display the error message: " - Name is too long" validates_length_of :name,

I''ve noticed that validates_format_of will return invalid if the field is nil. Question 1) How should we declare a validation that will validate it with a regex if it is set, but, if the field is not set, just move on Question 2) Why is it done this way? The other validators are only invoked if the field is set . If you want to declare the field mandatory, you add a

Been manually testing file column with success except it seems to upload the file before validating it. Also .pdf files (which shouldn''t even validate) crash WEBrick. What am I missing to solve these problems?

Can someone tell me why this returns ''dob is invalid'' when dob is ''01/01/1969''? validates_format_of :dob, :with => /[0-9]{2}.[0-9]{2}.[0-9] {4}/, :message => ''is invalid'' I''m trying to validate a date entred into a form.

Often I need to do a one-off validation before Rails has had a chance to convert. For example, a date. Is there a general mechanism to cause validations to run on the raw input or do I have to resort to: private def validate unless attributes_before_type_cast[''date_of_loss''] =~ /^(\d+(-|\/)){2}\d{4}/ errors.add(''date_of_loss'', ''use the

What''s the best way to check a field to ensure it is a valid datetime? I could validates_format_of :with a regular expression for "yyyy-mm-dd hh:mm:ss", but I''m wondering if there is a more direct way to do this. -- Posted via http://www.ruby-forum.com/.

I''ve got a regex validation on one of the inputs to my application, a file path. Now these only ever come from trusted users (administrators), but it would still be good to catch the most obvious attempts at directory traversal, etc. I''ve already got a regex that only allows \w then -, . and /. However, I want to stop two dots in a row, so I was wondering how to make the
