Before updating scaffolding from new DB schema, try creating


#1

What does the message “error Before updating scaffolding from new DB
schema, try creating a table for your model (Legacy)” mean? My googling
shows that others have received similar messages, but it’s not clear to
me the import of the message.

Here’s what I’m doing which generates this error:

[thufir@localhost ~]$ mysql -u feeds -p
Enter password:

the database configuration file

MySQL (default setup). Versions 4.1 and 5.0 are recommended.

Install the MySQL driver:

gem install mysql

On MacOS X:

gem install mysql – --include=/usr/local/lib

On Windows:

gem install mysql

Choose the win32 build.

Install MySQL and put its /bin directory on your path.

And be sure to use new-style password hashing:

http://dev.mysql.com/doc/refman/5.0/en/old-client.html

development:
adapter: mysql
database: dummy
username: feeds
password: password
socket: /var/lib/mysql/mysql.sock

Warning: The database defined as ‘test’ will be erased and

re-generated from your development database when you run ‘rake’.

Do not set this db to the same as development or production.

test:
adapter: mysql
database: dummy
username: feeds
password: password
socket: /var/lib/mysql/mysql.sock

production:
adapter: mysql
database: dummy
username: feeds
password: password
socket: /var/lib/mysql/mysql.sock
