Hey All,
Executing: gem install mysql --no-ri --no-rdoc tells me that it
installed one gem without any errors. However looking at the folder
inside InstantRails, something seems missing. There is no lib for example.
Also, a simple line like this:
@content = Content.find_by_permalink('introduction')
Is throwing one heck of an error (here is a small bit of it):
Processing ContentController#index (for 127.0.0.1 at 2008-11-26

No my first assumption is, this is related to a bad mysql gem
installation but, for the sake of covering all basis, does anyone know
whether anything has changed in the way databases get's set-up in the
database.yml file in 2.2.2?
Current:
development:
adapter: mysql
encoding: utf8
database: osc_development
username: user
password: pass
host: localhost
Thanks for all assistance, thankfully I now see that it is not only me
struggling with this issue.
