Send Email with Ruby

Good evening! The scenario I encounter is as follows:

I have a screen that shows a form already filled out. At the bottom of the screen, there is a button to send the link from form via email. And that's where magic happens:

I use AJAX via JavaScript:

$('.send_email').click(function () {
    const url = (window.location.href).split("/");
    $.ajax({
        url: " /assessments/"+url[url.length - 2]+"/send_email",
        type: "POST",
        data: {"assessments_id": url[url.length - 2]},
        dataType: "json",
        success: function() {
            alert('Enviado...');
        }
    });
});

It is working very well. Taking the id contained in the URL and passing to request the POST.

In the send_email method, this is where it gets interesting: It's in a controller exactly like this:

  def send_email
    AssessmentMailer.assessment_report set_assessment
  end

The set_assessment method is this:

private
# Use callbacks to share common setup or constraints between actions.
def set_assessment
  @assessment = Assessment.find(params[:id])
end

And it's working fine.

What I need is to send the email through send_email . But whenever I try it returns with Status 204

When debugging the system does not go to the class / method that is requested.

Follow The Mailer

class AssessmentMailer < ApplicationMailer
  default from: "[email protected]"
  before_action :load_assessments

  # Subject can be set in your I18n file at config/locales/en.yml
  # with the following lookup:
  #
  #   en.assessment_mailer.assessment_report.subject
  #
  def assessment_report
    mail to: @assessment.collaborator.email , subject: 'QUALIDADE DE VIDA'
  end

  private
  def load_assessments
    @assessment = params[:assessment]
  end
end

Follows Model:

class Assessment < ApplicationRecord
  belongs_to :collaborator
  paginates_per 10

  after_create :send_report_email

  def send_report_email
    AssessmentMailer.with(assessment: self).assessment_report.deliver_now!
  end
end

Who can save my existence? Nothing but eternal gratitude! haha ha. Jokes aside ...
