am currently working on a rails project. When i tried to start rails server its throwing the following error:
=> Booting WEBrick
=> Rails 3.1.3 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting
/var/lib/gems/1.9.1/gems/activerecord-3.1.3/lib/active_record/connection_adapters
/sqlite_adapter.rb:439:in `table_structure': Could not find table 'dbrick'
(ActiveRecord::StatementInvalid)
My table name is 'dbrick'. I also Tried to rake db:drop and rake db:mirgrate. While migrating its throwing the following error:
rake aborted!
Could not find table 'dbrick'
Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)
This is my migrate file:
class CreateDbricks < ActiveRecord::Migration
def self.up
create_table :dbricks do |t|
t.text :description
t.string :video
t.string :video_html
t.string :image_id
t.string :option_id
t.boolean :choice
t.string :reach
t.integer :category_id
t.string :user_id
t.datetime :deleted_at
t.timestamps
end
end
def self.down
drop_table :dbricks
end
end
It will be so much help full if any one help me out of this. Thanks in advance.
Soluzione
I would try :
rake db:schema:load
To load your schema ( to which I believe its finding the error against your DB ).
If that fails, I would manually find the migration that creates your dbrick, locate the name of the file and copy and paste the number in the filename to produce this :
rake db:migrate:down VERSION=123412341234 # <-- where the number is the number you pasted
Look for errors. Occasionally one thing exists already, or doesn't exist already and prevents the migration from running all the way, and consequentially that would be the source of your error. If it goes successfully then rake it back up :
rake db:migrate:up VERSION=123412341234 # <-- where the number is the number you pasted
If it doesn't go successfully, then you'll have to put on your miner's helmet, and get your hands dirty with :
rails dbconsole
Which will take you into your database and you'll have to manually delete whatever table/column is preventing the migration from occurring. Once that is fixed, exit out and rake db:migrate:up
!
Altri suggerimenti
Have you migrated your database? rake db:migrate
If you have, drop your database (this deletes all data, so be careful - do it if you do not care about losing data in your db)
rake db:drop
This will clear out your database, and your schema. Then
rake db:migrate
This will re-migrate your schema.
