Rails: Merit Gem Badge Not Registering or Displaying

Question

I set up the following badge which registered in DB:

merit.rb

Merit::Badge.create!({
id: 1,
name: 'Five Tasks'
custom_fields: { img_url: '/images/badge.gif' }
})

I set up the following rule:

badge_rules.rb

grant_on 'tasks#create', :badge => 'Five Tasks', :temporary => true, :model_name => 'Task' do |task|
task.user_ids.count == 5
end

What I wanted to to happen is when the User created 5 tasks they would be issued a badge.

I see entries in the DB in merit_actions and merit_activity_log entries -- but I do not see anything in the badges_sashes which I assume is where they would show when the badge has been issued -- even though I have surpassed the threshold --

Also I am uncertain how to display the badges --- I am using:

<%= current_user.badges %>

Right now all I get is brackets -- what I want it to return is an image of the badge ---

Any assistance greatly appreciated.

Answer 1

Are you accessing the badge's custom_fields as a hash? Those custom attributes that you add into custom_fields like img_url, difficulty, color, etc... won't be accessible in simple dot notation ie. badge.img_url won't work. Instead you need to do something like badge.custom_fields[:img_url] or badge.custom_fields[:whatever_custom_attribute]. Hopefully, the fix will be that simple.

Answer 2

To anyone else with a similar question: I finally was able to display the badges using the following:

<% current_user.badges.each do |badge| %>
<%= image_tag (badge.image) %>
<% end %>

Answer 3

Update Rails 5

You have to specify the custom field param in the view :

/merit.rb

  Merit::Badge.create!(
   id: 2,
   name: "FirstComment",
   description: "Premier commentaire !",
   custom_fields: { category: 'activity', image: 'ITM_02.svg' }
  )

/view

<% @profil.badges.each do |badge| %>                               
   <%= image_tag (badge.custom_fields[:image]) %>
<% end %>
