Rails how to redirect if record is not found

Question

I am trying to redirect if the record is not found. The page is not redirect and I get the error record not found.

My controller:

def index
@link = Link.         


        

Answer 1

Very tricky one ... I found a simple solution for this.... This solution works for me

@link = Link.where(:id => params[:id]).first

I am using .first because .where will return an array.Yes, of-course this array has only one element. So, When there is no record with such id, it will return an empty array, assign a blank element to @link ... Now check @link is either blank or not....

Conclusion: No need to provide exception handling for a simple check It is problem with .find it throws exception when no record exist ... Use .where it will return an empty array
