UPDATE 4.17.2012: If you're on EY and not using custom chef recipes, you should start. A whenever recipe has been written and is detailed here. Info on how to start using custom chef recipes is here. It's not so bad, really. One gotcha: your "appname" in the recipe is not your rails application name, but your EY application name - these can be different things!

Things I wish I’d have known:
1. It does not matter if whenever is in your gemfile, you have to SSH to your EY server and install whenever as such: sudo gem install whenever
2. It will probably complain that you don’t have i18n installed, so: sudo gem install i18n

EDIT: You will have to repeat the two steps above ANYTIME you restart your EY instance!

3. If you want your crontab updated on deploy, make a file named deploy/before_restart.rb and stick this in it (make sure you replace ‘yourAppNameHere’, derp):

@rails_env = node[:environment][:framework_env]
run "cd #{release_path}; whenever --set environment=#{@rails_env}; whenever --update-crontab 'yourAppNameHere'"

This is called a ‘deploy hook’ and here’s more info.

I found the idea for this in an old EY forum post.

Interesting tidbit about a new law that is being passed. IL Senate Bill 840 allows for “Cottage food operations” (i.e. you can use your home kitchen), with several stipulations, if and only if you are selling goods at a farmers’ market. So if I wanted to sell my cakes at a farmer’s market and got the appropriate paperwork, I could, but I still couldn’t sell them to individuals specifically out of my home. I’d have to have a table at a farmer’s market. Which is pretty much useless to me. Oh well, it’s a step in the right direction.

The documentation for jsTree is thorough, but not particularly easy to read. If you are looking for an easy way to add “Expand All” and “Collapse All” buttons, here’s one way:

<input type="button" value="Collapse All" onclick="$('#tree_container_id').jstree('close_all');">
<input type="button" value="Expand All" onclick="$('#tree_container_id').jstree('open_all');">


where ‘#tree_container_id’ is, of course, the ID of the container node for your tree.

Here’s an interesting read from Ars Technica:

Did file-sharing cause recording industry collapse? Economists say no

The most interesting paragraph I see in this article is this one:

So what is emerging is an increasingly “ephemeral” global music culture based not upon the purchasing of discrete physical packages of music, but on the discovery and subsequent promotion of musicians through file sharing. The big winner in this model is not the digital music file seller, but the touring band, whose music is easily discoverable on the ‘Net. As with so much of the rest of the emerging world economy, the shift is away from buying things and towards purchasing services—in this case tickets to concerts and related activities.

So I have to wonder – to my friends (and my husband) who count on selling merch at their unpaid performances – is this a game changer? Will musicians from now on be ultimately unable to make a living unless they go on the road – and stay there?

I have a textarea with the id of “request_details”, made into a CKEditor instance by jQuery: $(‘#request_details’).ckeditor();

(Check this page if you need some help getting CKEditor to work with jQuery, it’s dead simple)

Feature looks like this:  And I fill in "Here are some details" in the CKEditor instance "request_details"

Step looks like this:

When /^I fill in "([^"]*)" in the CKEditor instance "([^"]*)"$/ do |value, input_id|
browser = page.driver.browser
browser.execute_script("CKEDITOR.instances['#{input_id}'].setData('#{value}');")
end

I’ve decided on my least favorite phrase in the English language:

“Can’t you just…?”

Why is this my least favorite phrase? Because:

1. It’s always in conjunction with a task that the questioner does not understand, but assumes should not be difficult at all;
2. it is inherently second-guessing the person being asked, which is insulting;
3. and, rather than asking if something is possible, as in “Can you?” or “Could you?”, the speaker is really saying, “This must be possible, and if you can’t do it, you’re an idiot.”

If you don’t understand how the system works, or what is involved with doing a task, please, ask if something is possible. Don’t demean the craftsman or browbeat them into doing whatever it is you want. A resentful craftsman is not on your side, and will not go out of his/her way to help you.

Another edition of Sara uses Rails on Windows! *muppety fanfare*

Trying to get mysql2 to run on Windows is a bit of a pain. I used the lovely installer from Railsinstaller.org and then created an app with :

rails new testapp -d mysql

and then bundled.

By default this installs the mysql2 gem. There are some gotchas, and hopefully this will help:

1. You have to install mysql first (derp!). Go here and pick either the 32 or 64 bit MSI installer, and use this guide to pick your options during the install (section II). I know, it’s an old guide, but it works fine. And it has pictures!
2. You may get this error: “%1 is not a valid Win32 application.” This means you need to go here and get libmysql.dll, and copy it into c:\RailsInstaller\Ruby1.8.7\bin. Get the right version or your migrations will fail when you try to add indexes – the MySQL 5.5.9 64-bit version of libmysql.dll will NOT work! I got this version and it worked just fine: mysql-connector-c-noinstall-6.0.2-win32-vs2005.zip (you don’t need the MSI installer for this one, just grab a zippy file).
3. Next error you may get is “rbreadline.rb:4404: uninitialized constant RbReadline::Encoding (NameError)”. Thanks to this blog post I found the answer is to go into c:\RailsInstaller\Ruby1.8.7\lib\ruby\site_ruby\1.8\rbreadline.rb, and comment out line 4404.

There you go! Rake away!

Banged my head against this for a while. Starting a new rails project, trying to get rails.js from github, but it’s failing every time:

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (OpenSSL::SSL::SSLError)

So (after a lot of googling) I opened up gems/jquery-rails-0.2.7/lib/generators/jquery/install/install_generator.rb and added this just after the beginning of the InstallGenerator class (“class InstallGenerator < ::Rails::Generators::Base”) :

require ‘openssl’

OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE

Lately I’ve been installing Ruby on Rails on Windows 7, and have run into a few people trying to make my life easier. One is Sarah Mei, a wonderful member of devchix who has posted a guide for getting things running.  Hearts and bunnies and flowers for her.

Pik is a neat project for Windows that helps you switch between installed versions of ruby. I’m using the Git Bash shell (as mentioned in the guide above), so I had to do a bit of tweaking, and maybe you do too, so here goes:

For some reason the installer didn’t create my .pik/.pikrc file in my home directory, so if yours didn’t create either, this is how it should look:

#!/bin/sh
pik_path=C:\\pik

function pik {
$pik_path/pik_runner.exe pik.sh $@
[[ -s $USERPROFILE/.pik/pik.sh ]] && source $USERPROFILE/.pik/pik.sh
unset GEM_HOME
unset GEM_PATH
}

Those last two lines within the pik function are because something isn’t working in the current version and the gems aren’t being loaded when you switch versions.

Once you have your .pikrc add this line to your .bash_profile (create one if you don’t have it in your home directory):

[[ -s $USERPROFILE/.pik/.pikrc ]] && source $USERPROFILE/.pik/.pikrc

Hooray!
