  before_action :events_params, only: [:create, :edit]




  def index

  end

 def show
    @event = Event.find(get_event)

  end

  def new 
   @event = Event.new
  end

def create
    @event = Event.new(events_params)

    if @event.save
      redirect_to events_path, notice: "Almacenado"
    else
      render "new", notice: "Danm"
    end

I have too low rep to comment.

Please show the view of the form . It appears as if the parameters doesn't live up to your

params.require(:event)

Edit:

I think you do not use your event_params the right way, you should call this function only when you want to check the given parameters and look for your permitted attributes.

You should remove the

before_action :event_params

But add:

before_action :get_event, except: [:new, :index, :create]

This will make sure that you will set the current event in the @event-variable before show, update, destroy.

I think your culprit could be that you do not have an update-method, you appear do this in your edit-method as well.

edit is the action that loads the page where you can edit your event. updateis the action that you send to from your form. This is where you will use @event.update(...).

So your edit and update can look like:

def edit
end

def update
  if @event.update(event_params)
    redirect_to @event, notice: 'Event was updated'
  else
    render action: :edit
  end
end

(If you added the before_action :get_event).
