"errors prohibited" message when adding new todo item

I am getting the following error when the new or edit todo item page loads: "0 errors prohibited this todo item from being saved:"

+downloaded the program files and my model validations looks correct +form partial matches Jason's file +controller matches

What am I missing that would cause the error to render before any action is taken?

Hey Chad Flores :

Could you explain this a bit more? I'm getting the same errors, and so I feel like it must be something that was missed somewhere. Were you getting this? And if so, how did you fix it?

zero-errors

Maybe I just need to wait for a later video?

Hi Jim Withington ,

Not sure if this question is stale at this point, but I ran into the same issue, and I think it's an issue with the video.

Basically, when you copy/paste the code from the new and edit.html.erb files into the partial, you need to bring the if-statement with it and surround the "Error Explanation" div. So the partial would have this code in front of the div:

<% if @todo_item.errors.any? %>

and the end tag after the div:

<% end %>

For some reason, Jason doesn't add this in the example, and I'm not really sure why (different version of Rails? In any case, I'm not sure how the div would NOT show on the page in Jason's version, so if the video is right, I'd love someone to explain why it works).

if you use PUMA or WEBRICK as server, just take a look in the console what he is doing while you fetch that error message. Maybe the problem is not in the View or the Controller, i think you will find it in the "Validations" inside your model.

Just take a look in the console, and spot for SQL querys that have been executed

Turns out the <% if @todo_item.errors.any? %> and <% end %> wrapper in my form was missing.
