On pg 120/121 we add the method ‘ensure_not_referenced_by_any_line_item’, which executes the following code if a product belongs to a line item:
@errors[:base] « “Line Items present”@
If I fire up the console and check a product using @product.errors@, I can see that the error has been added. But, from what I can see, the error is never displayed to the user.
So my question is: How would I go about displaying this error? I played around with putting some code in the product index, but I can’t actually get the error to display.
Any help would be greatly appreciated
