I am new to Rails and I have a pretty simple problem with calling javascript functions from within a view. In Rails 2 I would do... = javascript_tag "name(arguments)" where the javascript function "name" was located in my application.js file. However, this does not appear to work in Rails 3? Or am I missing something? I have been sear...
I'm learning Ruby and RoR at the moment, and I came across this: <% for post in @posts %> in the Rails guide. I'd understood that the idiomatic way to do this in Ruby is with: <% @posts.each do |post| %> If there is a difference then what is it? And if there isn't a difference then wouldn't it be better for the Rails people to be p...

Before I start rolling my own using Rmagick I though i'd ask as this is probably a quite common use case. I have a few hundred email addresses which I would like to display to the user for each entry however I would like to avoid displaying the emails as plain text to avoid scraping, so I'm looking for some text-to-image solution. It ...
In which I mean "rebasing" in the dictionary, rather than git definition... I have a large, long running Rails project that has about 250 migrations, it's getting a touch unwieldy to manage all of these. That said, I do need a base from which to purge and rebuild my database when running tests. So the data contained in these is importa...

We're adding an expires_at column to one of our models. Among other changes, we've got to track down everything with a belongs_to relationship to the model and add the condition that expires_at must be in the future. Is there a way to do this centrally, so that rather than modifying all the other models, we modify the one that expires?...

Hello guys, Rarely our system mixes logged in users and I can't figure out why. Here is the scenario: 2 users log in (A and B) normally each one has his own ID, at some point one of the users (A) takes the ID of the other user (B) and contribute to the website as if he is B. Technically that's what is going on: 1- 2 users logs in: ea...
