Question

I’m using rails 2.3.4

When I execute rake db:test:prepare the id field created is not a primary key and auto-incremented.

When I look at the development db no problem with the primary keys.

Using MySQL.

Edit: It looks like my schema.rb file was changed :id => false should be true. What generates this file? DB Migrations?

[EDIT] What is the actual mechanics for generating the schema.rb file?

Answer 1

When you perform rake tasks, the tasks are executed to the default environment if no environment is specified.

You probably have different schema versions between your test and development databases.

rake db:reset #drops and created the database for current environment
rake db:reset:all #drops and creates database for all environments
rake db:migrate #migrates the schema for the current environment
rake db:migrate RAILS_ENV=test #migrates the schema for the test environment

If I’m not wrong (as I remember right now)

rake db:migrate #applies the migrations and dumps the schema to db/schema.rb file
rake db:schema:dump #dumps the actual state of your current environment schema into db/schema.rb file
