Hi all,

I have just a little problem. I want to save an object back to my  
database table.

if I do itlike that:

e = Event.new(params)  
e.save!

e.id returns the correct id of the created db entry

however if I do it like that.

e = Event.new(params).save!

e is just true (which is correct, but I hoped I’ll get back the object)

Can you tell, I am still not very familiar with Ruby :-/

How can I do this in one line?  
Thanks for a hint  
Karl

You’re setting e to the return value of save! You can use create!  
though:

e = Event.create!(params)

Yes, I can tell. You will find using Rails much easier and more  
productive  
if you actually know Ruby. Go learn it.

(e = Event.new(params)).save!
