curious_messenger's Issues

Part 3 - Blog post missing code

First of all I want to say thanks for taking the time to write this series of Blog Posts :)

The blog post for part 3 doesn't mention that we need to add the plug assign_user.ex and to add to PageController the line:

plug CuriousMessengerWeb.AssignUser, preload: :conversations

Also the blog post mention that for conversation.ex we should add this code:

schema "chat_conversations" do
  # ...
  has_many :conversation_members, ConversationMember
  has_many :conversations, through: [:conversation_members, :conversation]
end

But in instead the repo have this code:

# ....
has_many :conversation_members, ConversationMember, on_replace: :delete
has_many :users, through: [:conversation_members, :user]

Without this we get an exception:

[error] #PID<0.788.0> running CuriousMessengerWeb.Endpoint (connection #PID<0.786.0>, stream id 1) terminated
Server: localhost:4000 (http)
Request: GET /
** (exit) an exception was raised:
