Does Rails have built in support for alternating table row colors? Thanks, Sam

Hello, Say I want to make a multiple regression model with the following expression: lm(y~x1 + x2 + x3 + ... + x_n,data=mydata) It gets boring to type in the whole independent variables, in this case x_i. Is there any simple way to do the metaprogramming for this? (There are different cases where the names of the independent variables might sometimes have apparent patterns or not)

Hi all, I''m trying to move a bunch of methods out of a controller into a library that I can include and call a class method to have it dynamically add a bunch of methods to the controller. The goal is to just add to each controller: include UIEnhancements::SubList sub_list ''Note'', ''incomplete'' and have the sub_list method create all the methods

In HAML I have hundreds of lines like the following: - xyz = someFuncThatReturnsString(''xyz'') and elsewhere %div{''id'' => xyz} The above lines work fine. - - - Attempting to keep things DRY (Don''t repeat yourself) I want to do something like - eval(otherFuncThatReturnsString(''xyz'')) where

I''m having trouble succesfully getting access to the ActionView::Helpers::TextHelper.strip_tags method from one of my controllers. If I try to call it directly using ActionView::Helpers::TextHelper.strip_tags I get undefined method `strip_tags'' for ActionView::Helpers::TextHelper:Module What is the preferred way to make ActionView helpers available to a descendant of

I have a model that deals with HTML and I want to use the text_helper.sanitize method to strip the HTML of Javascript. However, it doesn''t appear that I can get easy access to the text_helper methods from within a model. Anyone have any suggestions for how to do this? In general, I think that there are some ActionView helpers which are generic enough to want to use in a model class.

All, I have a little namespace collision here. I am trying to use both RubyfulSoup (an HTML parser - which I highly recommend by the way) and the ActionView::Helpers::TextHelper class. Within the TextHelper class, there''s an attempt to create a new "Tag" object. However, Tag is also defined in the RubyfulSoup gem and it is _this_ Tag class whose initialize method is

Hi! I wanna take a stab at implementing better XSS prevention for Rails. This time for real =) I''m wondering what would be the better way, clean everything up with tidy first and then do the rest with regexp or regexp all the way? Anybody done this before? Thanks! Ciao! Florian

I''m a newbie to rails, and really to the whole DRY and MVC thing as well, except where I accidentally fell into things doing it my own way in the past. I''ve got a fairly complex DB structure I want to create an interface for using Rails. Getting simple tables to display, edit, save, not too much problem there. But where I''m having trouble is figuring out where to

Hi, This is more of a Ruby question than Rails. I want to autolink url''s in a given string. I''m not great with regular expressions and I wandered if anybody has an example. Thanks.

I have a MySQL "text" element that I''m trying to display, but it''s not formatting (i.e. it''s all one big paragraph). In the AWD depot example it doesn''t look like they do anything special, but they get formatted text. I''ve tried it with both: <%= show.description %> - puts text, and formats according to any HTML tags I typed in.

Hello. First, I want to thank those responsible for Dovecot IMAP as it was a real treat to implement in comparison to my mostly-failed attempts with Cyrus. The passwd-file authentication was exactly what I needed as I really didn't want to have to deal with PAM or LDAP but where I am setting up a server with virtual accounts. I'm using Postfix as an MTA, and it quite handily passes

Hi @ all I would like to enter a text with a text_area into the database. It runs excellent. But when I want to show the entered text in the show view, all newlines (paragraphs) are deleted and the text is only one block. How can I save the returns (newlines) too?

So I''ve googled my brains out, and I see a lot of talk about TextHelper for views, but next to no discussion about cleaning text _before_ it is saved. I figured this had to be asked 4 zillion times, but I''m not finding anything concrete/obvious. Using h is fine as a safety catch, but that alone is not acceptable to me as the means of diffusing the impact of HTML or JS

I''ve checked the Rails documentation but find no mention of link_to ''external url'' or equivalent. Does rails have a built in method to do this? thanks -Lindsay -- Posted via http://www.ruby-forum.com/.
