Question

What is wrong with this statement

@lastloc = Location.all(:customer_id == resource.id , :order => 'created_at DESC').first
if (@lastloc.longitude != params[:customer][:longitude] && @lastloc.latitude != params[:customer][:latitude])
  ...
end

What i am trying to do is to grab all Location with a certain id, then order then with the latest one then verify if different value then i proceed else do nothing

Answer 1

You can do something like this:

Location.where("customer_id = ?", resource.id).order('created_at DESC')

The IF condition looks ok, you can modify the “&&” for “and”, but that is a question of style only.

If you are not certain about the record being retrieved from the database you can start a rails console and check the record, the command is:

rails c -s

This will start a rails console in sandbox mode (all your modifications will roll back after you quit the console).
