Can't update existing records in Rails app

Question

It appears that everything saves properly on my Rails 4 app (using simple_form) when I create a new event, but when I try to update an existing event (by going to events/3/edit), it doesn't save any of the changes.

Here is my console log:

After this happens, I get a blank update event page with no form fields on it. I then return to the event index and go back to the individual event only to find that it's the way it was originally. Whatever it's doing, it seems to be sending information twice (the original info first and then the updated), but for some reason the updates don't seem to be sticking.

For what it's worth, the def update portion of the event controller is empty and i'm using a postgresql database.

This is what I ended up doing, based off this (replacing the word user with event): https://www.railstutorial.org/book/updating_and_deleting_users#sec-unsuccessful_edits

events_controller.rb:

def update
    @event = Event.find(params[:id])
    if @event.update_attributes(event_params)
      # Handle a successful update.
    else
      render 'update'
    end
  end

Maybe deleting the else render 'update' might avoid the blank "update an event" page that shows up after I do it, but this is more of a back-end feature (users aren't going to have a link to edit these events) and it accepts changes, so i'm content.
