GRANT: help me!

Rails
1

I have a database with grants commands setted (for admin, user, …).
How can I connect each users with database (according with db rules) in
rails?
When rails application start it is connected according database.yml…
but I need a right connection based on user type!

Thanks!!

I’m not sure I understand the question.

Are you talking about authenticating a users connection to the
database inside your application?

If so that has nothing todo with the rails database connection. You
need to lookinto a plugin that will do authentication and
authorization on the rails application side…

OR

You want to lock down the access that you application has to the
database?

GRANT SELECT,DROP ON app_production.* TO ‘someuser’@‘somewhere’
IDENTIFIED BY ‘somepassword’;

That gives someuser connecting from host somwhere SELECT and DROP
access to the app_production database with the password
somepassword ???

Does that answer your question or am I way off?

I’ve grant commands setted into database (with GRANT SELECT…), 3
grant (for 3 user types).
For ex, if you are connetted to Log In ‹ myhost.com — WordPress, you will be prompted
for insert your account information and rails will be connected to
database with “admin” user… nothing more, nothing less :wink: .
I know that this don’t sound good, but I can’t modify my db… and db
have grants and views…
If there are some trick to avoid this…

Thank you

Something like this?

ActiveRecord::Base.establish_connection(
:adapter => “mysql”,
:host => “localhost”,
:username => “admin”,
:password => “password”,
:database => “database”
)

(I’ve hear about it but…)
You think that I need to create a “singleton” class that have “n”
instances of database?? It’s the only solution??

Please help me with code samples!! This isn’t a trivial project and I
need something concrete, otherwise I need to take another language
solutions… and I really don’t want!!

Not necessarily. How many kinds of db user accounts do you have? Are
they fixed, or do you have a variable number of them?

Three db accounts, and they are fixed.
