Rails一对一消息传递

Question

Want to create real time direct messaging with user to user association, Though cant see exactly how to create this.

Example: User1 clicks the image of User2 from their contacts list, User1 creates a message and it sends to User2. User2 can see the message and replies back (like instant messaging) and both users see the same messages.

The message would have a title, image and body (each being available but not mandatory) The old messages and new message ability would be on the same page with old messages above the new message ability.

There is also the idea of how the messages are represented when reaching a user, if they are in conversation the messages appear in real time, if not in conversation then the contacts image would appear on the conversation page. Where you click a user to see the conversation.

I think part of the trouble is how do you identify the second user. Thinking along the below lines:

model User:

has_many :conversations
has_many :messages through => conversations

model Conversation:

has_many :messages
has_many :users

model Message:

belongs_to :users through => conversations
has_many :conversations

The tables would be along the line of:

message:

body
title
image
conversation_id

conversation:

message_id
user_id

user:

id

Any ideas/thoughts?

Try this:

user.rb:

has_many :messages
has_and_belongs_to_many :conversations
# id

message.rb

belongs_to :user
belongs_to :conversation
# body
# title
# image
# conversation_id
# user_id

conversation.rb

has_many :messages
has_and_belongs_to_many :users
# id

conversations_users.rb

belongs_to :user
belongs_to :conversation
# conversation_id
# user_id

Note: With this structure can also have more than two members.

Hope this help. :)
