When I save and submit code without modifying or adding anything, I get the message :
Oops, try again. Make sure to put an expression after each =!

I've been struggling with adding metadata to the ActionMailer Preview-header for a while.
What I would ideally like to do is to override the following file somewhere, adding some custom metadata to the header like in the picture attached below:
https://github.com/rails/rails/blob/4-2-stable/railties/lib/rails/templates/rails/mailers/email.html.erb
Alternatively override the mailers controller to render a different template on preview:
https://github.com/rails/rails/blob/4-2-stable/railties/lib/rails/mailers_controller.rb
Is it possible to easily override either of those files without having to change the base gems or similar? Would an extra initializer be needed and if so what should be included?
Hope someone here has some insights!
Best,
David

Soy nuevo en Ruby On Rails, estoy desarrollando un aplicativo donde los Docentes acceden por medio de correo y clave (configurado con la gema devise), pueden crear estudiantes y crear reportes de los mismos.
Estos son los modelos:
officer: (Para los usuarios en este caso los Docentes)
class Officer < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :events
include PermissionsConcern
end
event (Para los reportes de cada estudiante)
class Event < ActiveRecord::Base
belongs_to :student
belongs_to :officer
has_many :comments
end
student (Para los estuddiantes)
class Student < ActiveRecord::Base
validates :documento, :colegio, :nombres, :apellidos, :tipodocumento, :genero, :fechanacimiento, :edad, :etnia, :depto, :ciudad, :localidad, :barrio, :grado, :jornada, :discapacidad, :dirresidencia, :telcontacto, :nombreacudiente, :nombremadre, :nombrepadre, presence: true
has_many :events
end
Siguiendo un tutorial cree la siguiente migración:
class AddOfficerIdToEvents < ActiveRecord::Migration
def change
add_reference :events, :officer, index: true
add_foreign_key :events, :officers
end
end
En el controlador del Reporte puedo crear un reporte para cada Alumno (events_controller):
class EventsController < ApplicationController
before_action :authenticate_officer!
def create
@student = Student.find(params[:student_id])
@event = @student.events.create(event_params)
redirect_to student_path(@student)
end
private
def event_params
params.require(:event).permit(:fechareporte, :fechaevento, :lugar,:descripcion, :officer_id)
end
end
Sé que en esta línea de código:
@event = @student.events.create(event_params)
Se crea y se guarda el reporte, y asocia automáticamente el Alumno. Pero quiero poder mostrar el email del Docente que realizo el reporte, y no sé cómo modificarla para que almacene el officer_id del usuario logueado para saber que Docente realizo el reporte del alumno., he buscando en internet pero no he encontrado como.
Ayuda…! Por favor.
Agradezco su amable colaboración.
Gracias.

I am not an expert in that area, nor in Heroku. Have you determined
whether it is a Heroku issue or a production environment issue? If
not then try running it locally but in production mode and see what
happens.

I would start by looking at the contents of that file with a text editor, see if there is any XML in it. (Note: you may need to convert the file from a Zip package before you can do that, or use a Mac and BBEdit (which can read "into" Zipped formats like ePub and XSLX and show the plain-text contents therein). The Excel-reading gems that I know of only work on "modern" Excel, the XML-based formats. I've not heard of this XSLB format before, could it mean that it's a binary file? You should know when you look in the package. If it does turn out to be that, you may need to use something like OpenOffice or a Windows server and COM objects to deal with it.

Ruby On Rails Interview Question And Answers:
Q.Explain how (almost) everything is an object in Ruby:
- This is a simple question based on complex concept. Here's your chance to show off your theoretical knowledge and demonstrate that you can have an in depth conversation on class hierarchies, inheritance, methods, encapsulation, polymorphism, and more.
Q.What's your favorite testing tool?
The specific answer here is probably not important in and of itself – What's important is that you can demonstrate familiarity with at least several testing tools, and be able to discuss their individual advantages and weaknesses. Never ventured outside of Rails default testing tools? Take some time to familiarize yourself with tools such as Rspec, FactoryGirl, Capybara, and Cucumber
Q.What are Gems and which are some of your favorites?
- Short answer: Gems are packaged bits of Ruby code that you can install to extend or add functionality to your app.
Be sure to be able to discuss a list of your favorite gems, why you like them, and any customizations you like to add. This is also a good opportunity to highlight any gems you may have published.

I'm not sure what you're referring to for "different values" but on my
system I can quickly confirm elasticsearch is running by using this:
curl http://localhost:9200
Do you get a response to that? If not, ES isn't really running :-)

Hi again Thanks It seems using apt-get install elasticsearch on linux mint 18 gets you a non-working installation so elasticsearch github page says to download the source, unzip and run bin/elasticsearch but then the system complains the package has to be installed into init.d first So I figured I'd just install the deb Surprise, there is no .deb file in the distributions/deb directory Referring to the README.textfile also says to run bin/elasticsearch So then how shall I install?

It would help if you
1) provided a link to the "step 4.3" you referenced
2) copy and paste the error message so it can be run through
Google translate or equivalent
3) specify the versions of Ruby and Rails you're using
