How do I structure a Conversation between two models?
I have a
Store object that has an
email_address attribute. Using the logic from and How To Build A Form and Handling Inbound Email Parsing with Rails, I'm trying to figure out how to structure a Conversation where a visitor can email the Store, and the Store can reply through email - their replies would post messages to the Conversation.
When a visitor inquires to the store (via form), I create a
Reservation record with their name and email, and start a
Conversation like this,
@conversation = Conversation.create(sender_id: self.id, recipient_id: self.store_id)
I wanted to model the notifications similar to this, where everyone but the sender receives an email, but I'm stumped on how to map the User, since it's two different objects (Reservation and Store):
def send_notifications! (forum_thread.users.uniq - [user]).each do |user| UserMailer.new_post(user, self).deliver_now end end
The Conversation model looks like this, may be wrong, any guidance on what I could use to make the messages unique and structure the notifications?
class Conversation < ApplicationRecord belongs_to :sender, :foreign_key => :sender_id, class_name: "Reservation" belongs_to :recipient, :foreign_key => :recipient_id, class_name: "Store" belongs_to :reservation has_many :messages, dependent: :destroy end
The Message Post isn't fully fleshed out, not sure what to use to make it unique between the two Objects.
class Message < ApplicationRecord belongs_to :conversation validates_presence_of :body, :conversation_id def send_notifications! end end
Talor, would you mind posting the message model as well?
Just updated the bottom of the thread Casey; needing some guidance on setting up the Conversation and Message between two different models.
My assumption: A conversation is only between 2 people
So I think one thing that would make this easier to by putter an author_id on a message. This way you know who composed and sent the message. If you do this then you can just send a notification on the
after_create callback of the Message model. In that callback I would do something like.
def after_create UserMailer.new_message(self.id).deliver_later end class UserMailer def new_message(message_id) message = Message.includes(conversation: [:sender, :recipient]).find(message_id) recipient = message.conversation.sender_id == message.author_id ? message.conversation.recipient : message.conversation.sender mail(to: recipient.email) end end
What does your code like that receives and parses the email?
I haven't written the portion to parse the email and create the post, but I planned to model it around the logic here, Handling Inbound Email Parsing with Rails
I didn't realize I could access
conversation.sender so easily, going to try to model it as you suggested above Casey :thumbs_up:
