Create_<association?>


#1

Any know issues with the dynamic create_ method and
factory_girl?

I have an object created by a factory:

@order = Factory.create :payable_order_with_line_items

and then I do:

@order.create_ship_address(<attributes for ship_address)

then the ship_address object is persisted but the association is not
made (e.g. @order.ship_address_id is nil).

If I instead create the Address object and then say
@order.update_attributes(:ship_address => address), everything is fine.

Is this some issue with mixing factory-created objects with non? I
can’t imagine that’s an issue…

Thanks,

I don’t think it’s an issue w/FactoryGirl. A belongs_to association in
Rails adds the create_xxxxx association method, which returns a new
object of the associated type that has been instantiated and saved. It
does NOT save the receiver. For example:

@order.create_ship_address

This creates a ShipAddress and it updates @order’s in-memory
ship_address_id, but it does not save @order. You have to do that.
Here’s the example the Rails docs gives:

Post#create_author (similar to post.author = Author.new;

post.author.save; post.author)

Which in this example, the post is never saved, only it’s in-memory
association is set, so you still need to save @order in your example.

HTH,
