Failure/Error: get :index NoMethodError: undefined method `<=' for nil:NilClass

I hope this is not a specific error and it may be a logic error that can help others as well.

I want to test my controller index method, and i have a before method with an active record query. The problem is that i can't figure what is wrong with my test because i get this error only when using rspec and not when i test it manually.

Controller

class BlogsController < ApplicationController
  before_filter :archive_months

def archive_months
@months = Blog.find(:all, :select=>:publish_date, :order=>"publish_date DESC")
                .select{ |p| p.publish_date <= Date.today }
                .group_by{ |p| [p.year, p.month, p.publish_date.strftime("%B")] }
end

Test

require 'rails_helper'

RSpec.describe BlogsController, :type => :controller do
  before(:each) do
    @post1 = create(:blog)
  end
  describe "GET #index" do

    it "shows all blog posts" do
      get :index
      expect(response).to have_http_status(200)
    end
  end
end

Test output

1) BlogsController GET #index shows all blog posts
     Failure/Error: get :index
     NoMethodError:
       undefined method `<=' for nil:NilClass
     # ./app/controllers/blogs_controller.rb:178:in `block in archive_months'
     # ./app/controllers/blogs_controller.rb:177:in `select'
     # ./app/controllers/blogs_controller.rb:177:in `archive_months'

If i run the @months query on the page or in rails console it works well, but on my test in does not work.

It seems you have one or more Blog objects in your test database that don't have a publish_date attribute set. That's why .select{ |p| p.publish_date <= Date.today } raises the error.
