Developer Disaster Drawer

In my case, I wanted to get a complete list of valid urls to use Helium-css (to clean all the unused css of the project) and to take the advantage of the routing, I executed this command (you should replace BASE_URL to your base_url:

app/console router:debug | awk '{print "BASE_URL"$3}'

Do you have an error executing a rake task using the new rails version?: Just do the following:

bundle exec rake

alias rake="bundle exec rake"

In my case is .twig but you can do it for any extension. It’s simple and you can check it in wiki ack’s page but if you’re not too acquainted with these kind of things, just do the following:

mate ~/.ackrc

--type-add
php=twig

--type-set=sass=.scss
--type-set=coffee=.coffee

Playing with Firebug console, if you edit a number value you can do:

With arrows (↑/↓) increments are 1[+/-].

So far I knew this… but if you press at same time ⌘ the variations will be 0.1[+/-] or if the key pressed is ⇧ will be 10.

It’s a stupid thing but I didn’t know it and it useful for me. I hope you too.

mkdir -p ~/Library/Application\ Support/TextMate/Bundles

cd ~/Library/Application\ Support/TextMate/Bundles

git clone git://github.com/charlesr/ruby-sass-tmbundle.git "Ruby Sass.tmbundle"

osascript -e 'tell app "TextMate" to reload bundles'

Homebrew is wonderful but sometimes it can be a little headache. For example, if you’ve created a rake task with ruby that assume a role called postgres (by default), probably if you installed with brew you won’t have it. Brew get your system user and unless your name would be postgres, you have to create it. For this reason, I’m going to write the easy steps to create a new role with admin privileges. Remembering, you did:

brew install postres

initdb /usr/local/var/postgres

mkdir -p ~/Library/LaunchAgents

cp /usr/local/Cellar/postgresql/9.0.4/org.postgresql.postgres.plist ~/Library/LaunchAgents/

launchctl load -w ~/Library/LaunchAgents/org.postgresql.postgres.plist

env ARCHFLAGS="-arch x86_64" gem install pg

psql -d postgres < /usr/local/Cellar/postgresql/9.0.4/share/postgresql/contrib/adminpack.sql

psql -d postgres

postgres-# \du

postgres=# CREATE ROLE postgres SUPERUSER CREATEDB CREATEROLE LOGIN;

Today I founded an error with a plugin called Stylish Select (for customized selects). My select was contained in a hidden content (for filtering searches) and the plugin didn’t customize correctly my combo element. Its height was 0. And what’s the problem?, all its calculated operations are wrong. What’s the solution?, simply. Just find that hidden element (respect a concrete element):

var elToShow = $(this).parents(":hidden:last");

if (elToShow.html() != null && elToShow.html().trim()){ // not empty
        var hideElement = 1;
        elToShow.show();
  		}

if (hideElement) elToShow.hide();
