When I have for example only one record for administrators (only one administrator) with id and password, is it necessary to create a table administrator or not? Why?
There's nothing inherently wrong with a one record table. It's a function of your design. For example, an administrator is not a type of user so you wouldn't stick an administrator in the user's table. But that's a design decision.

How to find vulnerable sites, where one can login using '0'or'0'='0' and such other combinations ?
I believe you are asking the question with reference to to SQL injection. If the login control is using a query based on string concatenation then chances are that this will succeed in logging in.
It should be: ' or '0'='0

I want to implement a authorization system, that should work on permissions for each individual records.
e.g. User U1 can Read a Record R1
User U2 can Edit/Delete Record R1
i.e. Each Record will have its own set of permitted users for Create/Read/Update/Delete. I dont want tot implement Role based system.
Is there any rails gem/plugin to do that ?

We are searching for a while now on google to find out some good SQL scripts to
create a "forum". Does anyone know some great start up kit (Image, scripts, schema view) from what I could start? We want something with the most functionalities as possible (such as number of views, ranking, etc).
Check the existing forum projects like phpbb.
