Hello,

how can I find out the table name of an object?

For example I have the object ua of the class UserArticle:  
ua = UserArticle.find(1)

How can I find out it is saved in the table user\_articles?

With AR::B.table\_name :

UserArticle.table\_name

# =\> “user\_articles”

If you have the name of the class in a string and you’re  
following Rails conventions (and assuming you haven’t a prefix  
or a suffix), then you can write :

‘UserArticle’.tableize

# =\> “user\_articles”

Thank you Jean-François. I just found out that it is this easy:

This is not what I initially asked for, of course. I meant to say it is  
as easy as this:

ua = UserArticle.find(1)  
ua.class.to\_s.tableize
