render :text => request.domain()

Apache Lucene and Ruby

Robert Dempsey has written a nice article about ‘Using Amazon S3, EC2, SQS, Lucene, and Ruby for Web Spidering‘, which is very interesting because it describes how to interact with Apache Lucene using Ruby.

datetime_select seconds

I’ve just looked for the possibility to include the seconds into Rails’ DateHelper function datetime_select. After i haven’t found it in the Rails API documentation i tried to add an extra parameter include_seconds, set it to true and voilà … it worked like a charm:

<%= datetime_select("post", "written_on", :start_year => 1995, :include_seconds => true) %>

no such file to load — mysql

Daniel — Thu, 18 Dec 2008 22:59:45 +0000

I got the error

no such file to load — mysql

when running my Rails application. After that i tried to install the mysql gem module using

sudo gem install mysql

but it gave me an error saying:

ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.

I then included a parameter to the install command which showed the path to the mysql_config file

sudo gem install mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config

That did the trick.

undefined method `cache_template_loading=’ for ActionView::Base:Class

I got the following error message when trying to run a Rails application with passenger after updating Rails:

undefined method `cache_template_loading=’ for ActionView::Base:Class

I had to comment or remove the line

config.action_view.cache_template_loading = true

in the production.rb file to fix the problem.

Just stumble on a Ruby on Rails online deployment service: Heroku. Don’t know if its good, but it looks promising.
