around this issue The query User.joins(:cars).where('cars.color' => "blue") returns an ActiveRecord::Relation instance. Check docs here.
If you really want to operate over an instance (of User class), you must take a user from that collection, for example:
@user = User.joins(:cars).where('cars.color' => "blue").first

Ruby on rails - Helper method - undefined method `log_in' in Ruby on rails

this one helps. You are missing the ApplicationController part here which includes the helper in the controller so its methods can be accessible directly:
class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  include SessionsHelper
end

Rails NoMethodError: undefined method `valid?'

should help you out There's not a valid? method for an ActiveRecord collection. If you're trying to test that the last Ticket you created is valid, you can do something like assert @ticket.valid?.
I think you might be doing a bit too much work in your setup method. You could try to just setup your User and Event model in the setup, and break the rest of what you described into different test blocks.

ruby on rails undefined method 'valid' when using update

I wish did fix the issue. ActiveRecord update(id, attributes)
Updates an object (or multiple objects) and saves it to the database, if validations pass. The resulting object is returned whether the object was saved successfully to the database or not.
def update
  @user = User.find(params[:id]) //Find user
  if @user.update(user_params) // Update user if validations pass
      redirect_to "/users/#{@user.id}"
  else
      flash[:errors] = @user.errors.full_messages
      redirect_to "/users/#{@user.id}/edit" 
  end
end
User.update(params[:id], user_params)
