I am just getting into Ruby on Rails, after successfully failing at
getting any other programming language to work locally. RoR appears to
be a repeat! One problem I keep running into is getting a database up
and running.
I’m working out of Windows XP.
I installed MySQL, it works, runs, will create tables etc. BUT, when I
do rake db:migrate…it fails and tells me I have a bad descriptor.
I’ve spent over 24 hours now searching, uninstalling, reinstalling,
deleting, re-creating everything, and to no avail. SQLite also doesn’t
want to work. I am a TOTAL newbie to programming, so I have no idea
what’s needed or wanted by any of each of these little things I
installed. I just follow the instructions, install what they recommend
and cross my fingers.
Also, I’m not connected to the internet via XP, so I had to manually
download and install ALL gems, how fun. Anyway, do I NEED to be
connected for the MySQL gem, or should I already have it? What should
I have in order for everything to work, so far I have WEBrick running,
I have an IDE, I have the package manager, I have Ruby installed, it’s
only the dbs that are haunting me.
I’ve checked the database.yml file and MySQL and WEBrick are both
running. I don’t get it.
I downloaded that link and followed the instructions, didn’t work.
The password for MySQL is different than the password for the database
correct?
When I created the database I typed: mysqladmin -u root -p create
depot_development
It asks for a password and I type the MySQL password. This doesn’t
create a password for the database does it?
The following is the requested info:
c:\depot>rake db:migrate
(in c:/depot)
rake aborted!
Bad file descriptor - connect(2)
(see full trace by running task with --trace)
001_create_products.rb
class CreateProducts < ActiveRecord::Migration
def self.up
create_table :products do |t|
t.column :title, :string
t.column :description, :text
t.column :image_url, :string
end
end
def self.down
drop_table :products
end
end
What does this mean?
Install MySQL and put its /bin directory on your path.
Especially the path part, I put the /bin directory in c:/depot/ or
is it supposed to be the folder where Rails is? Do I move it, or copy
it? Thanks!
I also just checked and there are no conflicting ports. WEBrick is
listening on 3000 and MySQL is listening on 3307…nothing else is
using either of these two. I’m still mystified by on your path.
try in command line: gem install mysql
(or gems, dont member exactly)
in selection choose latest win32 gem
if “gem” or “gems” are “Bad command or file name”, this mean Rails are
not installed properly.
setting for mysql connection are in config/database.yml in your rails
appication,
Also i suggest to “install” InstantRails, it’s windows application
that really helps to control your apache/mysql/ruby/rails servers
properly, also it have
all extentions needed for rails programming. also useful because it
not loading your memory when dont needed.
You can find it at rubyforge (http://rubyforge.org/projects/
instantrails/)

PhpMyAdmin is really powerfull app to admin you mysql.

So it wasn’t - you had already installed gem mysql… I’ve never heard
of adding a port to a database.yml file. I’d like to know more.
Please post your solution in detail…
