Railscasts Alternatives

Posted on: July 10th, 2014 by AstonJ 5 Comments

As many of you might know, I LOVE Railscasts – and like many of you, I miss Ryan heaps. He has a knack of being able to make things look super easy; his screen casts enable you to learn a great deal in just a few minutes. I often joke that it is a bit like the Matrix – we look something up, then we know kung fu! Rails Kung Fu of course!

I don’t know about you, but my Rails learning has taken a severe dip since Ryan has been away (I hope you are ok Ryan!!) though, it has also tied in with some personal problems as well, which has left little time for learning anything to be honest.

But the time has come to get back into it, and I hope to put together a list of Railscasts alternatives to tie us over till Ryan comes back. If you can think of any that you feel should be included, please leave a note in the comments to let me know. More…

If you’re getting this error (probably after a bundle update), all you need to do is comment out:

require "whenever/capistrano"

Form your deploy.rb file, then deploy as usual, then uncomment it, and deploy again. Simple huh?

How to get Capistrano to ignore upload directories (Carrierwave)

Posted on: June 23rd, 2012 by AstonJ 5 Comments

As you probably know, Capistrano creates a fresh directory for your app every time you deploy a new version. So if you want some directories (or files) to be carried through to each version, such as files uploaded by users, then we just need to tell Capistrano that they are shared – and to use the /shared directory for these files instead. Which is done by creating symbolic links. Here’s how.

Add this to your deploy.rb file:

Intro to Git – 5 mins to see why it’s awesome

Posted on: June 9th, 2012 by AstonJ No Comments

This is more a handy reference for myself, but it also acts as a very quick intro to why git is awesome and well worth using. The main difference here is I remind you what the state of your working directory is as you make changes (as this was what confused me previously – as I wasn’t quite sure what was going on). I assume you’ve installed git already – and know what it is.
