My client model, when I send the email reminders. Problem is, I would like to send user information, not sure how to pass in the correct

client.rb

## My daily mail function that sorts through who should be sent email reminders, then passes that 
##infomation to the mailer function

## The client side works [Line 18 ], it finds all appropriate clients and sends to them 
## However I decided that I want to include information from User.
## User has many clients, So the person that signs up is the User, and the clients are sent email reminders.

##My issue is that, I wasn't sure how to pass in the correct user instance into the Reminder.daily_mail email function
## When I try it how it done now, it sents emails reminders with ALL users. @user = User.current_user doesn't work.
## When I try to do a block each user, it send loops and send multiple emails.

def self.daily_email
    @user = User.all

    @user.each do |u|
      @user_name = u.name
    end
    @client = Client.all
    @client.each do |c|
      unless c.email.nil? || if c.reminder == "Daily" && c.paid == false 
        puts "Daily fixed | Company Name " + @user_name + "Client Name | " + c.name
        Reminder.test_mail.deliver
        Reminder.daily_email(@user_name,c.id,c.email,c.project_name,c.name,c.amount,c.due_date).deliver
        
      end
    end
    end
  end

reminder.rb

def daily_email(user_name,id,email,project_name,name,amount,due_date)
      @user_name = user_name
      @id = id
      @name = name
      @project_name = project_name
      @amount = amount
      @due_date = due_date
      @client = Client.find(id)
      mail(:to =>email, :subject => "Reminder from "+ @user_name )
      puts "Inside Daily email sent method"
      @client.update_attributes(last_email: Time.now, email_sent: true)
      
    end
