How to build a notification feed using Stream

How to build a notification feed using Stream

Introduction

In this tutorial we are going to show how easy it is to build a notification feed using GetStream.io. First of all, let's quickly introduce you to our fictional example app. It's called bug-your-friends.com and allows you interact with your friends, ping them, follow them or poke them. Here's a quick list of example interactions:

  • poke another user (eg. Thierry pokes Alessandra)
  • follow a user (eg. Tommaso follows Iris)
  • ping a user (eg. Josie pings Carolina)

Whenever a user is part of one of these interactions, we want to update his notification feed, update the number of unseen and unread

generate random string from a canonical for, useful for software responding like humans
#!/usr/bin/env ruby
# generate a single sentence from a canonical form
# canonical sentence is a multi sentences combined in one
# form, generator will generate a sentence from it randomly
# based on the form, for example:
# "Hello [Emad|Elsaid]" , may generate "Hello Emad" or
# "Hello Elsaid" the result is random.
# also you could nest [] inside each other to gain a multi level
# canonical sentence example:
# "[[Hi|Hello] [Emad|elsaid] | good [morning|night] sir]"

Using rails_admin without devise

Having a buckload of code to authorize users on your application is something you may like or not. Speaking for myself I hate it. But I still love rails_admin, here's how you install it without devise. Thanks to phoet for providing the hints in the gist I have forked from.

Add RailsAdmin to your Gemfile

do NOT add devise

gem "rails_admin", :git => "git://github.com/sferik/rails_admin.git"
