rake db:reset doesn't work, fails with unknown attribute: user_status

If I manually drop the database, and run create, then migrate it works fine.

But doing a:

rake db:reset

it fails with:

unknown attribute: user_status

Does this mean my migrations are not dropping things correctly?

I believe that rake db:reset re-creates the db and loads the schema from schema.rb rather than running the migrations [1]. Is there something odd in schema.rb, possibly related to user_status?

It would be nice if there was a way to mirror things to RAILS_ENV=test also.

I hate having to do it for both.

First thing to do seems to check with --trace.

$ rake --trace db:reset

and study the order of execution of rake tasks in detail until the

point where it fails …

Why doesn’t rake -T show db:reset? Where can I find a list of these hidden rake commands?

Why doesn’t rake -T show db:reset?

Because the desc is not defined or is commented out.

Checking these files could help you. The migration tasks are

in the first one.

As you will see, some tasks have no desc above them,

or the desc is commented out (probably because it is

not intended as a public available command).

E.g. rake db:reset is defined as such:

db_namespace = namespace :db do

…

desc 'Drops and recreates the database from db/schema.rb for the current env

ironment and loads the seeds.’

task :reset => :environment do

db_namespace[“drop”].invoke

db_namespace[“setup”].invoke

end

…

end

with the desc commented out.

and rake db:migrate:reset as such:

db_namespace = namespace :db do

…

namespace :migrate do

…

desc ‘Resets your database using your migrations for the current environment’

task :reset => [‘db:drop’, ‘db:create’, ‘db:migrate’]

…

end

…

end

HTH,
