How to set field automatically in Rails

I have a simple feedback form to allow the Users send the feedback. Controller for it:

class FeedbacksController < ApplicationController
  expose(:feedback, attributes: :feedback_params)

  def create
    ApplicationMailer.customer_feedback(feedback).deliver_now if feedback.save

    respond_with(feedback, location: root_path)
  end

  private

  def feedback_params
    params.require(:feedback).permit(:email, :message, :name, :phone)
  end
end

Here I'm using expose gem. And the view for it:

= simple_form_for(feedback, url: feedback_path) do |f|

      legend
        = t(".any_questions")

      .form-inputs
        = f.input :name
        = f.input :email
        = f.input :phone
        = f.input :message, as: :text

      .form-actions
        = f.button :submit, t(".submit")

I want the next: to check somewhere if current user present(logged in to application) If yes = then set the email field using user.email (when he visit the feedback form -> email should be already filled in. If user not logged in to site then this field should be empty. Where should I put this logic? Thanks!

The simple form documentation explains how simple form is very easy to customize according to your needs. Assuming you are using devise for user authentication (if you're not, simple_form is designed to work with devise so you should check it out), then you can user current_user to access the currently logged in user.

I think simple_form's input_html would help you here: 

= f.input :email, input_html: { value: "#{current_user.email if current_user}"}
