I'm writing an application that allows users to send one another messages about an 'offer'.
I thought I'd save myself some work and use the Mailboxer gem.
I'm following a test driven development approach with RSpec. I'm writing a test that should ensure that only one Conversation
is allowed per offer. An offer belongs_to
two different users (the user that made the offer, and the user that received the offer).
Here is my failing test:
describe "after a message is sent to the same user twice" do
before do
2.times { sending_user.message_user_regarding_offer! offer, receiving_user, random_string }
end
specify { sending_user.mailbox.conversations.count.should == 1 }
end
So before the test runs a user sending_user
sends a message to the receiving_user twice. The message_user_regarding_offer!
looks like this:
def message_user_regarding_offer! offer, receiver, body
conversation = offer.conversation
if conversation.nil?
self.send_message(receiver, body, offer.conversation_subject)
else
self.reply_to_conversation(conversation, body)
# I put a binding.pry here to examine in console
end
offer.create_activity key: PublicActivityKeys.message_received, owner: self, recipient: receiver
end
On the first iteration in the test (when the first message is sent) the conversation
variable is nil
therefore a message is sent and a conversation is created between the two users.
On the second iteration the conversation created in the first iteration is returned and the user replies to that conversation, but a new conversation isn't created.
This all works, but the test fails and I cannot understand why!
When I place a pry binding in the code in the location specified above I can examine what is going on... now riddle me this:
self.mailbox.conversations[0]
returns a Conversation
instance
self.mailbox.conversations[1]
returns nil
self.mailbox.conversations
clearly shows a collection containing ONE object.
self.mailbox.conversations.count
returns 2?!
What is going on there? the count
method is incorrect and my test is failing...
What am I missing? Or is this a bug?!
EDIT
offer.conversation
looks like this:
def conversation
Conversation.where({subject: conversation_subject}).last
end
and offer.conversation_subject
:
def conversation_subject
"offer-#{self.id}"
end
EDIT 2 - Showing the first and second iteration in pry
Also...
Conversation.all.count
returns 1!
and:
Conversation.all == self.mailbox.conversations
returns true
and
Conversation.all.count == self.mailbox.conversations.count
returns false
How can that be if the arrays are equal? I don't know what's going on here, blown hours on this now. Think it's a bug?!
EDIT 3
From the source of the Mailboxer gem...
def conversations(options = {})
conv = Conversation.participant(@messageable)
if options[:mailbox_type].present?
case options[:mailbox_type]
when 'inbox'
conv = Conversation.inbox(@messageable)
when 'sentbox'
conv = Conversation.sentbox(@messageable)
when 'trash'
conv = Conversation.trash(@messageable)
when 'not_trash'
conv = Conversation.not_trash(@messageable)
end
end
if (options.has_key?(:read) && options[:read]==false) || (options.has_key?(:unread) && options[:unread]==true)
conv = conv.unread(@messageable)
end
conv
end
The reply_to_convesation
code is available here -> http://rubydoc.info/gems/mailboxer/frames.
Just can't see what I'm doing wrong! Might rework my tests to get around this. Or ditch the gem and write my own.
