Need Help Resolving ActiveRecord::RecordNotFound Error

Hi everyone,

I’m encountering an issue with my Rails application and I could really use some guidance. I keep getting the following error:

ActiveRecord::RecordNotFound in UsersController#show
Couldn't find User with id=123

I’ve checked my database and the user with ID UR987 definitely exists, so I’m a bit puzzled as to why I’m getting this error. I’ve double-checked my controller and view files to make sure everything is set up correctly, but I haven’t been able to pinpoint the source of the problem.

def show
  @user = User.find(params[:id])

And here’s the relevant part of my view file:

<%= %>

I’m using Rails 6.1 and Ruby 3.0. Could this be a version-specific issue, or am I missing something obvious in my code? I also check this : Handling ActiveRecord::RecordNotFound errors ruby on rails But I have not found any solution. Please guide me in this.

Thanks in advance!

The little bit of code that you posted looks fine.

But you mention “ID UR987”. Why?

The code looks fine, but the id ActiveRecord is querying is different from the id you mentioned. Can you show us the URL you’re requesting in the browser? Also, doing puts params.inspect or just puts params can reveal a lot.
