Can't delete the todo list entry

Hey all,

Have a problem whereby clicking on the 'destroy' button doesn't actually delete the entry! Clicking on destroy only redirects me to localhost:3000/todo_lists/1 , where the number 1 refers to the entry number. I noticed that it's an alert prompt that comes up when you click destroy, so it must be an issue with the javascript

I'm running the latest version of rails (4.2.5), on a windows 10 using the Cmder interface.

Any help is greatly appreciated! Thanks!

Hi Kaiyang, it is possible that some code in your javascript intercepts the click event and does not submit the form. Your destroy method in the controller is probably not executed. I suggest you use the gem, byebug (https://github.com/deivid-rodriguez/byebug), to trace your ruby code. You should also be aware of what this javascript command does: http://www.w3schools.com/jsref/event_preventdefault.asp. I know this does not solve the problem, but these are some tools to help you.
