how to call actionmailer in rails admin controller?

Question

I want to send a email to user after create something via rails admin.

I know I can call it in model callback but it's not considered as a good pratices

the best way is to put the actionmailer action after model save in the controller but I don't know how to do it in rails_admin controller

class UsersController < ApplicationController
  # POST /users
  # POST /users.json
  def create
    @user = User.new(params[:user])

    respond_to do |format|
      if @user.save
        # Tell the UserMailer to send a welcome email after save
        UserMailer.welcome_email(@user).deliver_later

        format.html { redirect_to(@user, notice: 'User was successfully created.') }
        format.json { render json: @user, status: :created, location: @user }
      else
        format.html { render action: 'new' }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end
end

What you want to do is not easy on rails admin because you cannot modify the controllers nor do you have access to them without monkey patching them.

I actually made a fork of rails admin for this functionality checkout the commit with the changes: https://github.com/aliada-mx/rails_admin/commit/6251554efd1d83cdb418f42683ee55a4e27c2474 Just touched two files

And example usage

class User
   after_save :on_admin_updates
   attr_accessor :edited_in_rails_admin

   def on_admin_updates
      return unless edited_in_rails_admin
      self.edited_in_rails_admin = false

     UserMailer.welcome_email(self.id)
  end
end

A bit clunky i know, PR´s welcome.
