I know this has been rehashed many times, but I don''t get it. I can''t find it documented to were I understand all the parts. I can make this work using Rails database design conventions, but in this case I am not able to do that. I find examples, but the ones I find do not follow the conventions. They also do not give enough information to understand what is going on. In

Greetings all, This is the first release of the SuperImage plugin. The idea is you upload images to the database, and then pull them out at any size you want. Combine this with caching and it will stay light and fast.

Hello, I have about 2000 data files which I want to analyse. The file names are all very similar => p"variable1"_t"variable2"_c"variable3".txt There aren?t so much different variables (about 70) , just different combinations of them. To allow an easy way of handling those data files I was wondering whether R is able to do variable-substitution

I am able to display all the images once I get them all, but that causes an unacceptable delay for my user. One approach I am trying is, from my controller, set an @image variable, and then pass in a block to the model that retrieves the

hi guys, I have show_image problem. I have the following code in application_helper.rb in my rails project def show_image(src,img_size) img_options = { "src" => src.include?("/") ? src : "/images/#{src}" } img_options["src"] = img_options["src"] + ".gif" unless img_options["src"].include?(".")

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

Hi you all, I am reading the Rolling with Rails article, by Curt Hibbs. In the beginning, when he is explaining how to install the MySQL Server, he comments we mustn''t set up any account cause MySQL uses an authentication algorithm that is not compatible with the current version of Rails. Is there any way to avoid this and establish an account with its password? (I am using MySQL 5.0

Hi, I spent more than 4 days getting done with the "Four Days with Rails" tutorial, mostly because I ran into a few issues that seemed to stop me in my tracks.  But, after looking around, I was able to find the problems and solve them (in whatever way I thought best) :-) I''m posting the whole list of problems that I ran into with "Four Days with Rails" to the list so

Hi you all, I have a model simulating an ActiveRecord model, according to the tips stated in [1]. It is simulated because even though I am gonna save the attributes in a file, not in a DB, I still want the validations made by ActiveRecord::Base (see code below). Well, the thing is that I also want the behaviour of the created_on and updated_on columns, that get modified automatically before

Hey all -- I''ve been using enumerable char(1)''s with ''y'' and ''n'' values for my Boolean columns in Rails, but it strikes me there should be a better way. How do you setup columns that represent true/false-ness in your schemas on Rails? Wondering what kind of standard approaches there are other than me writing something like class MyEntity
