Hi Daniel,

never faced such problems,

normal usage is

rake migrate

which uses development environment settings for connecting to db

if you want to migrate on production environment use this

rake migrate RAILS_ENV=production

hope this helps.

if you still have issues, give relevant contents from database.yml, and
environment.rb

will try to help

you seem to be using windows and error shows postgres, hope it is not
different database in development and production :)

I am getting something similar, and do not know what do.
This is what I get:

-------------
rake aborted!
Don't know how to build task 'db:migrate'
-------------

I am trying to follow the Agile Web Development with Rails 2nd ed, and
am getting stuck right at the beginning of creating the Depot
application.

I am running on Windows XP, and have installed Ruby via InstantRails
(1.0 final).

Any help greatly appreciated -- as I am stuck and cannot proceed.

please run following command on your app

ruby script/about

please confirm you have followed the procedure

1) you have created a rails project
2) configured db
3) use migrations for creating models
4) you have a file "Rakefile" in your rails project directory
5) you are running "rake" in your rails project directory

now please tell about your os, and mysql version,
can you connect to mysql with with phpmyadmin.

if you cannot sort out the issue, please paste the output of "ruby
script/about" will investigate

if you use postgresql,maybe you need change "postgres" to "postgresql"
in your database.yml file.

sorry for my poor english:)
