Brilliant Chris! It helps to have a direct example to understand the documentation.

Posted in HTTParty and trycelery.com API

Ok. I have tried for 3 days and I'm not getting anywhere.

I am building a small kickstarter style campaign module for several products that will be run through Celery. What I want to accomplish is the following:

  1. Retrieve a list of products (id and name) to be served in a dropdown when I build a new campaign.
  2. Retrieve the total number of orders for a specific product based on its id

Celery seems to allow all of the above (https://github.com/airbrite/celery-api/blob/master/README.md) but I am stuck trying to parse the GET response from the API.

I have a Campaigns controller:

class CampaignsController < ApplicationController
  def new
    @campaign = Campaign.new

   @response = HTTParty.get("https://api.trycelery.com/v2/products.json?limit=1&access_token=my_access_token")
   @http_party_json = JSON.parse(@response.body)

def create
  @campaign = Campaign.new(campaign_params)

  if @campaign.save
    redirect_to @campaign
    render 'new'


  def campaign_params
  params.require(:campaign).permit(:campaign_name, :product_id, :campaign_goal, :expiration_date, :ship_date)


In my new.html.erb for Campaigns:

<p>New Campaign</p>
  <% @http_party_json.each do | event | %>
    <% event.each do | e | %>
      <li><%= e %></li>
    <% end %>
  <% end %>

<%= render 'form' %>

Which renders the following JSON response:

{"code"=>200, "paging"=>{"total"=>8, "count"=>1, "limit"=>1, "offset"=>0, "page"=>1, "pages"=>8, "has_more"=>true}}
[{"_id"=>"5558cc89695f1d0a00c135d8", "slug"=>"c5251d8b-38ce-42be-918a-9809b2cf57dc", "name"=>"B3/B4 Gauge Face Kit", "description"=>"<p>A replacement gauge face kit for your Audi B3/B4.

followed by my form partial.

I'm after the "_id" and the "name" objects. Whats interesting is that the loop returns four

  • elements

    1. meta
    2. {"code"...}
    3. data
    4. [{"_id"...]

    Objective 1
    How can I target the 4th blob and parse that to obtain an array of just _id's and names?
    I want create that array so I can use it in my f.select so that it shows me the names but enters the _id in the database

    Objective 2
    I am trying to use the API to obtain a total number of unpaid orders related to a specific product _id.
    I am trying the following but not quite sure if it will succeed.


    orders = HTTParty.get "https://api.trycelery.com/v2/orders?payment_status=unpaid&line_items.product_id={_id}&access_token=my_access_token"
    @order_count = orders["total"].to_i
    @percent_complete = 100.0 * @order_count / 50

    I'm just testing on a single product but will be running 4 simulateneous campaigns so I will need to make this code more dynamic and loop through the products to obtain the @order_counts for each product.

    Any help would be fantastic as its quite difficult to wrap my head around this being super new to RoR.

    Success! Everything works! I'm thinking it had something to do with the listen on port 80 since its now uncommented.

    Chris, thank you! Its been days of trying to deploy this!!

    Tried cap deploy:migrate and get the following error.

    /Users/ebishop/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/capistrano-3.1.0/lib/capistrano/i18n.rb:4: warning: duplicated key at line 6 ignored: :starting
    Stage not set, please call something such as cap production deploy, where production is a stage you have defined.

    Tried 'cap production deploy:migrate' and it runs but the same error is displayed on the website.

    I'm thinking it has something to do with Nginx and not my rails app. I edited the config and changed the env to development and I get a migration error. I'm guessing I should redeploy the app in development?

    Here is my deploy/production.rb
    set :stage, :production
    server '', user: 'deploy', roles: %w{web app db}

    Hi Chris,

    Here is the link to the website.

    Everything works perfect locally but breaks in production. The only link that works is root. Everything else gives a 404

    Nginx config
    server {
    # listen 80 default_server;
    # listen [::]:80 default_server ipv6only=on;

        passenger_enabled on;
        passenger_app_env production;
        root /home/deploy/resume/current/public;
        index index.html index.htm;
        # Make site accessible from http://localhost/
        # server_name localhost;
        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
                # Uncomment to enable naxsi on this location
                # include /etc/nginx/naxsi.rules

    What else would you like to have a look at?

    I'm at a loss. After finally successfully deploying using Capistrano, and finally figuring out why my assets were missing, I have another issue. I have a link that point to static pages (contact) generated via a static_pages controller. Locally, the app works fine and I can visit the page but on production, I get a 404. I cannot find anything on SO on why this is happening and I'm lost. Any ideas? I followed the GoRails Deploy guide.
