The content_tag_for was available in Rails 3 and 4. It has been removed from Rails 5.

To bypass content_tag_for try this simple format - it works for me with Ruby 5:

          
        
<li class="category" id="category_<%= sort_category.id %>"><span class="handle"><%= sort_category.title %></span></li>

Checkout

ngrok.com

Once setup, running a subdomain is as easy as:

ngrok -subdomain=mysubdomain 3000

https://mysubdomain.ngrok.com -> 127.0.0.1:3000
http://mysubdomain.ngrok.com -> 127.0.0.1:3000

I used it to test PayPal's IPN for recurring subscriptions.

Mark Harper on #288 Billing with Stripe 2014-10-12 23:26:11

if you are getting empty values:

Stripe error while creating customer: You passed an empty string for 'card'. We
assume empty values are an attempt to unset a parameter; however 'card' cannot b
e unset. You should remove 'card' from your request or supply a non-empty value

Turn Off Turbolinks - wrap your links to the subscription form with no-data-turbolink. Turbrolinks is not re-loading the subscription.js.coffee on page load, so the code dosen't load the card values.

          
        
<div data-no-turbolink> <%= link_to 'New Subscription', new_subscription_path %></div>

update to stripe v2

          
        
<%= javascript_include_tag "https://js.stripe.com/v2/", 'application', 'data-turbolinks-track' => true %>

Drove me crazy!

Mark Harper on #88 Dynamic Select Menus (revised) 2014-05-28 21:50:09

Hey Jorge,

You should be able to include cities if you had a "cities.csv" which matched the states structure.

To answer the other part of your question:

The "states.csv" and "countries.csv" data files are available in the github hosted "Source Code" under the "Show Notes" header:

https://github.com/railscasts/088-dynamic-select-menus-revised

By using the "db/seeds.rb" file you can migrate the data into any rails app.

bundle exec rake db:seeds

I hope this helps for future use.

P.S.

My code is a little different:

First, I got carrierwave working as per 253-carrierwave-file-uploads

then..

          photos.js.coffee
        
jQuery ->
  $('#new_photo').fileupload
    dataType: "script"
    add: (e, data) ->
      types = /(\.|\/)(gif|jpe?g|png)$/i
      file = data.files[0]
      if types.test(file.type) || types.test(file.name)
        data.context = $(tmpl("template-upload", file).trim()) if $('#template-upload').length > 0
        $('#new_photo').append(data.context)
        data.submit()
      else
        alert("#{file.name} is not a gif, jpeg, or png image file")
    progress: (e, data) ->
      if data.context
        progress = parseInt(data.loaded / data.total * 100, 10)
        data.context.find('.progress-bar').css('width', progress + '%')

          _form_uploader.html.erb

      format.js
      format.json { render json: [@photo.to_jq_upload].to_json, status: :created, location: @photo }
    end
  end

Hey All,

Bootstrap 3 modifications:

          paintings.js.coffee
        
from:

data.context.find('.bar').css('width', progress + '%')

to:

data.context.find('.progress-bar').css('width', progress + '%')

And then

          index.html.erb
        
from:

<div class="progress"><div class="bar" style="width: 0%"></div></div>

to:

<div class="progress progress-striped"><div class="progress-bar" style="width: 0%"></div></div>

I hope this helps. I f'd around with this for hours install all new css, js files before it dawned on me to update the bootstrap css.

To Your Success!!! Mark

Hey... ... extremely late on this one - but just started a new app and needed reputation with pagination

          try
        
@newsletters = Newsletter.approved.page(params[:page]).per_page(NEWSLETTERS_PER_PAGE).find_with_reputation(:votes, :all, order: "votes asc")

By placing the "find_with_reputation" after pagination (will_paginate) works.

Mark Harper on #343 Full-Text Search in PostgreSQL (pro) 2013-05-27 02:35:02

Try bbarton's suggestion - it worked for us.

          from bbarton
        
modify...

where("to_tsvector('english', title) @@ :q", q: query)

... to..

where("to_tsvector('english', title) @@ plainto_tsquery(:q)", q: query)`

Also a couple of gotcha's was default scope and multiple includes.

We had to run the text_search as 'unscoped.where' and remove a couple of includes before any search results would displayed.

This app had one search query only on strings such as names, usernames, and email addresses (no full text searches). so we incorporated Ryan's Auto Completion:

http://railscasts.com/episodes/102-auto-complete-association-revised

It works great. Thank's Ryan!

A big thank you - worked for me

Mark Harper on #360 Facebook Authentication 2013-05-24 02:22:02

After upgrading to the latest jquery and adding Facebook 'Like' buttons, the sign-in popup window stopped functioning.

Firebug reported:

FB.getLoginStatus() called before calling FB.init().

To fix this, just move the "FB.init" call to the last position in facebook.js.coffee.erb.

          app/assets/javascripts/facebook.js.coffee.erb
        
jQuery ->
  $('body').prepend('<div id="fb-root"></div>')

  $.ajax
    url: "#{window.location.protocol}//connect.facebook.net/en_US/all.js"
    dataType: 'script'
    cache: true


window.fbAsyncInit = ->

  $('#sign_in').click (e) ->
    e.preventDefault()
    FB.login (response) ->
      window.location = '/auth/facebook/callback' if response.authResponse

  $('#sign_out').click (e) ->
    FB.getLoginStatus (response) ->
      FB.logout() if response.authResponse
    true

  FB.init(appId: '<%= ENV["FACEBOOK_APP_ID"] %>', cookie: true)

Worked for me - not sure why.

Maybe this can help those like Michael Elfassy, SMnetserv, pbaileyjr12 who have difficulty with double named countries.

On my app, everything worked fine until I accidentally 'bundle update' the gems.

After the bundle update, the double name countries (United States and United Kingdom) would not trigger and display the:

grouped_collection_select :state_id, Country.approved.includes(:states)

sidenote: bullet says to include states in the query.

I hope this helps:

          app/assets/javascripts/people.js.coffee
        
original
escaped_country = country.replace(/([ #;&,.+*~\':"!^$[\][()=>|\/@])/g, '\\$1')

modified
escaped_country = country.replace(/([ #;&,.+*~\':"!^$[\][ ][()=>|\/@])/g, '\\$1')

Mark Harper on #103 Site-Wide Announcements (revised) 2013-03-18 00:17:12

How to have only active announcement ids in the cookies.signed[:hidden_announcement_ids]

This is kind of 'amateur hour' code (my specialty), but:

After using site-wide-announcements for several months, the development log was passing several dozen expired ids on each page load:

          
        
SELECT "announcements".* 
  FROM "announcements" 
  WHERE (starts_at <= '2013-03-18 06:55:20.343948' and ends_at >= '2013-03-18 06:55:20.343948') 
  AND (id not in (10,9,23,45,32,12,6,7,8,76,4,8,90,5,43,2,67,54,3,2,6,5,67,89,2,8,9,7,54,6,7,32,24,56,77,7,53,2,1)) 
  ORDER BY id desc

I got tired of looking at all those ids, so as a test I tried to figure out how to have only active announcement ids in the cookies.signed[:hidden_announcement_ids].

Deleting the cookie was simple, but would re-display previously hidden announcements.

Here's my solution.

An 'active' name scope (id in (?)), as opposed to the 'current' scope (id not in (?))

          models/announcement.rb
        
  def self.active(hidden_ids = nil)
    result = where("starts_at <= :now and ends_at >= :now", now: Time.zone.now)
    result = result.where("id in (?)", hidden_ids) if hidden_ids.present?
    result
  end

An after_filter :flush_announcement_cookie, placed on the users' login landing dashboard_controller.

          dashboard_controller
        
  after_filter :flush_announcement_cookie

  def flush_announcement_cookie
    if cookies.signed[:hidden_announcement_ids].present?      
      ids = Announcement.active(cookies.signed[:hidden_announcement_ids]).pluck(:id)
      cookies.permanent.signed[:hidden_announcement_ids] = ids
    end
  end

Hope this helps somebody.

Here's a simple multi-rating system for Photos based of Ryan's videocast. It is simple: just pass the value as the params[:type]: vote_photo_path(photo, type: "1"). Aalso using twitter/bootstrap/font_awesome for the vote icons

vote:
Notice the current_user cannot vote on their own photos;

And I included a 'status' attribute for 'Approved' or 'Denied' the display/hide the photo from public viewing.

Automatic Quality Control: Notice the automatic status change to 'Denied' is ONLY after 10 votes and with an average value less than 3.

vote_range:
This is in the application_controller.rb because I use the reputation system on several models: Ads, Photos, Profiles.

vote_reset:
This allows for resetting the values.

voteable?:
Allows control of who can vote

          models/photo.rb
        
  has_reputation :review_photos, source: :user
  scope :public, where("status = ?", "Approved")

          models/user.rb
        
  has_reputation :review_photos, :source => { :reputation => :review_photos, :of => :photos }

          controllers/photos_controller.rb
        
def vote
      
    @photo = Photo.find(params[:id])
    
    if current_user
        
      if @photo.user_id != current_user.id
      
        value = params[:type]
  
        if vote_range?(value)
          @photo.add_or_update_evaluation(:review_photos, value, current_user)
        end
        
           # if low score on photo - automatically update status to "Denied" to hide from "Public" - @photos = Photo.public

        if @photo.reputation_for(:review_photos).to_i < 3 && @photo.evaluations.count >= 10
          @photo.status = "Denied"
          @photo.save
        end

      end
      
    end

... it was very simple to setup.

Hey if you get: undefined method `reputation_value_for'

change `reputation_value_for' to 'reputation_for'

reputation_value_for was deprecated and replaced by reputation_for, see commit (10/03/2012)

reputation_for(reputation_name, *args)

https://github.com/twitter/activerecord-reputation-system/commit/552c04b0dead76cd79fb3915845b17b6a8de0cca

Also normalized_reputation_value_for was deprecated and replaced by normalized_reputation_for

normalized_reputation_for(reputation_name, *args)
