To configure a Rails application in order to use SQLite3 please follow the following steps:
sudo apt-get install sqlite3 swig libsqlite3-ruby libsqlite3-dev sudo gem install sqlite3-ruby
Then create a Rails application as usual and update the environment.rb file in the following way
Rails::Initializer.run do |config|
...
config.gem 'sqlite3-ruby', :lib => "sqlite3"
...
end
If you work with subversion, for sure you had the problem to tell to subversion to ignore a folder inside your working copy. This happens for example if your IDE builds the sources in a folder inside your working copy. From the very first commit you’ll start noticing that subversion wants to add that “build” folder to your repository. But, obviously, this is not a good practice.
So you can tell subversion to ignore a folder. Just move in the folder that contains the folder you want to be ignored by subversion and type the following command.
svn propset svn:ignore <dir_you_want_to_be_ignored> .
The “dot” at the end is important! It means you’re specifying which folders of the current folder you want to be ignored.
Please note that <dir_you_want_to_be_ignored> should be written without trailing slashes. So for example if you want the build directory not to be managed by subversion, type…
svn propset svn:ignore build .
And not…
svn propset svn:ignore build/ .
This is a quick tip. I always forget how to do it, so I wrote that little note.
