Help with DRY: too much code in my view
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

I don''t even know how to ask the question (4 lines of code)
I create a hash using this line of code @x = Account.find(:all) I then want to go through each element in turn and add a key value pair to the end of it. I thought this would work, but it does not. @x.each do |a| a.merge({"balance"=>50} I used merge because I thought ''a'' would be a hash (how do you find out the type of an object?) I then guess it was

A book we may wish to buy
Hi: Some French fellow posted a notice yesterday about a book that had come out. It''s called "Ruby on Rails" and is apparently by DHH & David Thomas. Is this a scam? If not, does anyone know where I can buy this book in English? I''ve searched the usual places but can''t turn anything up. Bruce

Trying to grasp the difference between local variables and instance variables/
Hi: Would it be fair to say (or completely out to lunch) that a local variable is local to a method and an instance variable is local to an object. Thus an instance variable is a sort of limited global variable or super-powered local variable. Its scope is larger than a local but smaller than a global. Or that it is a global within a limited domain (the object). or is it a whole lot

How can one use GRUFF with locomotive ( I guess there is a wider question here, also)
Hi: I love Locomotive and use it exclusively for my rails projects. I''d like to install GRUFF and give it a try (a graph image creation package). I know I can do sudo gem install gruff from the command line for normal ruby and rails. How do I make gems available to Locomotive? bruce

repost - Can one edit the file that generates the scaffolding.css?
I am reposting this because not only am I VERY interested in the answer but because I think it would also be useful to many, many people. We kind of have a house-style here, so it would be nice if the generated scaffold.css would accommodate that. My questions are? Is it possible? Is it safe? How? bruce

I''d like to edit the scaffolding file - is it possible?
I notice that I begin each project with a standard css file which is the one produced by scaffolding PLUS some other stuff. I could cut and paste a copy from an old project but I thought it would be "cooler" amongst other things (like more efficient) to just have the scaffold.css file be created for me. Is it possible? Is it safe(ish), What would I have to do? Thanks in

Is Webrick good enough?
Hi all, On the rails list I''ve seen that it''s hard to integrate Rails with Apache (especially apache2), that it''s hard to change the default port (3000), and that Apache runs Rails stuff slowly. Is it reasonable to run Rails stuff on Webrick while simultaneously running other stuff on Apache? How does one simultaneously run two rails applications on Webrick, when

Zebra Striping a Collection of Partials
I''m using render to display a collection of partials, where each partial is a table row. Is it possible to zebra-stripe the table using this method i.e. alternate table rows get a different CSS class? I can''t work out how each row partial would know whether it was odd or even. In the normal scheme of things I could do: <% odd_or_even = 0 for asset in @assets

Want to use a view helper (TextHelper) in a model class
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.

Pay rates for Rails developers
Does anyone have an idea of the rates being charged by Rails developers (or salaries for FTEs)? I''m curious to see whether rates will become comparable to those paid to more experienced Java/.NET developer types, or if rates will be lowered by the free/open source mentality, and the possible perception that Rails makes Web development "easy." Sometimes rates are more
