| Chart.js in rails Posted: 26 Jul 2016 08:06 AM PDT I have discovered a problem that I, as I am new to rails and chart.js, can not solve. I want a graph that also shows data that are not in the label. Immoment I have the problem that I have a month on dates, I want only 5 labels(not 31 labels on the x-axis). Chart.js scans my data and submit only for the first 5 data listings dots in the graph but I also want to have dots between the labels. Here is my code <canvas id="orderChartLastMonth" width="400" height="400"></canvas> <script> <%= foo = ((Date.today - 1.month).beginning_of_month) %> var ctx = document.getElementById("orderChartLastMonth"); var orderChartLastMonth = new Chart(ctx, { type: 'line', data: { labels: [ "<%=foo %>", "<%=foo + 1.week%>", "<%=foo + 2.week %>", "<%=foo + 3.week%>", "<%=foo + 4.week%>" ], datasets: [{ label: 'Graph Orders last week', data: <%= (foo..foo.end_of_month).map { |date| Company.graph_order(date).to_f}.inspect %>, }]}, options:{ legend:{ display: false }}}); </script>
Company.graph_order selects only the orders from that date. Can you guys recommend using chart.js or is it the worst? If you have another solution, pls write it into the comments(it has to be non-licens) Greetings! |
| factory_girl linter failing because of ActionView::Template::Error Posted: 26 Jul 2016 08:23 AM PDT I'm in the process of working out the bugs for updating an app from rails 4.1 to rails 5. When I try to run my tests the factory_girl linter complains that some of the factories are invalid: /Users/stephen/.rvm/gems/ruby-2.3.1@ssa/gems/factory_girl-4.7.0/lib/factory_girl/linter.rb:13:in `lint!': The following factories are invalid: (FactoryGirl::InvalidFactoryError) * call_log - Undefined variable: "$green". (ActionView::Template::Error) * sms_log - Undefined variable: "$green". (ActionView::Template::Error)
etc. This is all factory girl really gives me for a stack trace. It tells me the where the linter is called but that is it. No indication where something might be going in the view. Is there a way for me to determine this? It seems like this is going to be very difficult to debug fi I don't know where it's coming from. |
| Using Capybara with Webkit to select an option from a Chosen Multiselector Posted: 26 Jul 2016 08:19 AM PDT I have a multiselector that uses the Chosen plugin as shown below: <%= select_tag :provinces, options_for_select(DataHelper::all_provinces_captions.zip(DataHelper::all_provinces_ids)), {:multiple => true, class: 'chosen-select chzn-select', :data => {:placeholder => 'Filter Provinces/States'}, :style => "width: 100%; height: 100px;"}%>
Here are the relevant DataHelper selection arrays: def self.all_provinces_captions usa_provinces_with_caption.map { |x| x.first } + canada_provinces_with_caption.map { |x| x.first } end def self.all_provinces_ids usa_provinces_with_caption.map { |x| (Province.find_by name: x.first).id} + canada_provinces_with_caption.map { |x| (Province.find_by name: x.first).id } end def self.usa_provinces_with_caption [["Alabama", "alabama"], ["Alaska", "alaska"], ["Arizona", "arizona"], ["Arkansas", "arkansas"], ["California", "california"], ["Colorado", "colorado"], ["Connecticut", "connecticut"], ["Delaware", "delaware"], ["District Of Columbia", "district of columbia"], ["Florida", "florida"], ["Georgia", "georgia"], ["Hawaii", "hawaii"], ["Idaho", "idaho"], ["Illinois", "illinois"], ["Indiana", "indiana"], ["Iowa", "iowa"], ["Kansas", "kansas"], ["Kentucky", "kentucky"], ["Louisiana", "louisiana"], ["Maine", "maine"], ["Maryland", "maryland"], ["Massachusetts", "massachusetts"], ["Michigan", "michigan"], ["Minnesota", "minnesota"], ["Mississippi", "mississippi"], ["Missouri", "missouri"], ["Montana", "montana"], ["Nebraska", "nebraska"], ["Nevada", "nevada"], ["New Hampshire", "new hampshire"], ["New Jersey", "new jersey"], ["New Mexico", "new mexico"], ["New York", "new york"], ["North Carolina", "north carolina"], ["North Dakota", "north dakota"], ["Ohio", "ohio"], ["Oklahoma", "oklahoma"], ["Oregon", "oregon"], ["Pennsylvania", "pennsylvania"], ["Rhode Island", "rhode island"], ["South Carolina", "south carolina"], ["South Dakota", "south dakota"], ["Tennessee", "tennessee"], ["Texas", "texas"], ["Utah", "utah"], ["Vermont", "vermont"], ["Virginia", "virginia"], ["Washington", "washington"], ["West Virginia", "west virginia"], ["Wisconsin", "wisconsin"], ["Wyoming", "wyoming"]] end def self.canada_provinces_with_caption [["Alberta", "alberta"], ["British Columbia", "british columbia"], ["Manitoba", "manitoba"], ["New Brunswick", "new brunswick"], ["Newfoundland", "newfoundland"], ["Northwest Territories", "northwest territories"], ["Nova Scotia", "nova scotia"], ["Nunavut", "nunavut"], ["Ontario", "ontario"], ["Prince Edward Island", "prince edward island"], ["Quebec", "quebec"], ["Saskatchewan", "saskatchewan"], ["Yukon", "yukon"]] end
How do I select an option from this chosen selector in a Capybara integration test on the Ruby on Rails framework? I have tried the conventional selector method, and that hasn't work, as well as the Capybara method for filling out textboxes - and that hasn't worked for me either. The HTML that the Chosen plugin creates from the ERB: <select name="provinces[]" id="provinces" multiple="multiple" class="chosen-select chzn-select" data-placeholder="Filter Provinces/States"

| omniauth-facebook error only when api version is over v2.2 Posted: 26 Jul 2016 07:52 AM PDT I received email from facebook that my rails app is using v2.0 api and it will be deprecated. so I updated gem like this. - devise (3.5.6) + devise (4.2.0) - oauth2 (1.1.0) + oauth2 (1.2.0) omniauth-facebook (3.0.0) omniauth-oauth2 (1.3.1)
I did not version up omniauth-oauth2 because of some unsolved issues. after that, I change some deprecated view codes. and changed my config and restart server. config.omniauth :facebook, APP_ID, APP_SECRET, scope: 'email', info_fields: 'email,name'
It worked well but the facebook api version was still v2.0. so I googled and found this. https://github.com/mkdynamic/omniauth-facebook#api-version says that it's default version is v2.6 but I don't know why it still use v2.0. anyway, I changed config code like this. config.omniauth :facebook, APP_ID, APP_SECRET, scope: 'email', info_fields: 'email,name', client_options: { site: 'https://graph.facebook.com/v2.6', authorize_url: "https://www.facebook.com/v2.6/dialog/oauth" }
but it did not work. log is like this. Started GET "/users/auth/facebook/callback?code=verylogcode&state=stateblabla" for 127.0.0.1 at 2016-07-26 22:52:03 +0900 (facebook) Callback phase initiated. (facebook) Authentication failure! invalid_credentials: OAuth2::Error, : {"access_token":"very_long_token_value","token_type":"bearer","expires_in":5160039} Processing by OmniauthCallbacksController#failure as HTML
I downgraded the config version to v2.3 but it did not work. from v2.2, it works. My Question is this. - why the omniauth-facebook does not use v2.6 at default config setting?
- How can I solve this problem? I googled this kind of erros but in my case, the log does not show error messages precisely. (OAuth2::Error, : actually vacant)

| Rails5 + ActionCable: WebSocket connection to 'ws://{hostname}/cable' failed: WebSocket is closed before the connection is established Posted: 26 Jul 2016 07:00 AM PDT I get WebSocket connection to 'ws://{hostname}/cable' failed: WebSocket is closed before the connection is established. in my chrome browser when connecting to my Rails 5 + ActionCable app. In my local development environment, it doesn't happen. It only happens in my staging and production environment. Successful screenshot on development Failed screenshot on staging I use Amazon ElasticBeanstalk to deploy my app. After monitoring requests with chrome developer tool, I figured out that unlike development environment, WebSocket request in staging, production environment doesn't get response(pending) so ActionCable constantly tries to connect to the WebSocket endpoint (ws://{hostname}/cable). The thing is, in my puma.log, it says something like this: I, [2016-07-26T13:45:53.921154 #32369] INFO -- : Registered connection (Z2lkOi8vYXNrLWNvLWRlL1VzZXIvMg) I, [2016-07-26T13:46:05.775788 #32369] INFO -- : Finished "/cable/" [WebSocket] for 121.166.105.106 at 2016-07-26 13:46:05 +0000 I, [2016-07-26T13:46:18.074895 #32369] INFO -- : [917fd706-4f1a-4178-bd95-7a33c0c7b621] Started GET "/cable" for 121.166.105.106 at 2016-07-26 13:46:18 +0000 I, [2016-07-26T13:46:18.075764 #32369] INFO -- : [917fd706-4f1a-4178-bd95-7a33c0c7b621] Started GET "/cable/" [WebSocket] for 121.166.105.106 at 2016-07-26 13:46:18 +0000 I, [2016-07-26T13:46:18.075817 #32369] INFO -- : [917fd706-4f1a-4178-bd95-7a33c0c7b621] Successfully upgraded to WebSocket (REQUEST_METHOD: GET, HTTP_CONNECTION: Upgrade, HTTP_UPGRADE: websocket)

| Passing a Rails Variable into a Controller Method Posted: 26 Jul 2016 07:41 AM PDT So, I've got a program that I've been working on for a while that is just a basic barcode scanning system. My controller for a raw good is as below: class RawsController < ApplicationController def new @raw = Raw.new end def create @raw = Raw.new(params[raw_params]) if @raw.save receive(@raw) redirect_to new_raw_path end end def receive(raw) scanned = Raw.find_by(code: raw.code) if scanned.quantity.nil? flash[:danger] = "no match" else scanned.quantity += 1 if scanned.save respond_to do |format| format.html {} format.json{} end end end end private def raw_params params.require(:raw).permit(:code, :product, :quantity) end end
Now, what I want to happen, is that when someone enters a barcode number into a form, it creates @raw as an instance of the Raw(for raw goods) class. Then in the receive function, it searches for a matching product in my inventory and then adds one unit to my raw goods inventory. However once I get to the scanned.quantity += 1 line, I continually get an error that this method is undefined for nil class. I added in the scanned.quantity.nil? line, and I do get that flash message, so I know the problem has to do with the quantity being nil. But, I'm not sure how to fix this. Any help? |

| How to pass data before create a subscription in ActionCable - uniq connections Posted: 26 Jul 2016 05:15 AM PDT In my ActionCable channel I want to have every connection unique. How can I do it and pass params before create a subscription and find the params in the subscribed method? Following the ActionCable documentation for all connections to same channel, the action starts here: ActionCable.server.broadcast "web_notification_channel", id: id, title: title
It launchs the JS file channels/web_notification.coffee App.link = App.cable.subscriptions.create { channel: "WebNotificationChannel"}, .. # connected: -> # disconnected: -> # received: (data) -> ..
It creates the subscription here: # app/channels/web_notification_channel.rb class WebNotificationChannel < ApplicationCable::Channel def subscribed stream_from "web_notification_channel" end end
Now I want to have for every connection a unique channel - following the documentation I would do something like this Start: ActionCable.server.broadcast "web_notification_channel#{id}", id: id, title: title
JS: App.link = App.cable.subscriptions.create { channel: "WebNotificationChannel", id: ?}
Subscription: def subscribed stream_from "web_notification_channel#{params[:id]}" end
The problem is the second step - how can I get the data ID - so I could pass it the last step as a param? I found this resource here but it's not a clear to me and I feel it's too complicated for my simple example. |

| Rails, remove flash message generated via ajax Posted: 26 Jul 2016 05:27 AM PDT I have a flash message which is generated by an ajax response. In my controller I have: def destroy flash[:danger] = "Successfuly destroyed" format.js end
which calls a destroy.js.erb file $('#flash_messages').html("<%= escape_javascript (render partial: 'layouts/flash_messages') %>");
that renders a partial which shows the flash messages. This partial looks like this: #flash_messages -flash.each do |key, value| = content_tag(:div, value, class: "flash alert alert-#{key}")
I would like to use jquery to remove the flash message after 2 seconds. What I tried was: $(".alert").fadeTo(2000, 500).slideUp(500, function(){ $(".alert").alert('close'); });
which, however, does not find the .alert class because it is generated after the page load. What is a workaround this problem :? Thank you! |

| How to avoid connecting to the Elasticsearch client when running rails generator or other tasks? Posted: 26 Jul 2016 04:54 AM PDT I have a rails (4.2.6) app that includes the elasticsearch-model and elasticsearch-api gems. When I run rails g model ... in order to generate new boilerplate code, rails tries to connect to the Elasticsearch server. This is, of course, easily remedied but a little annoying for local development. I have a guard in config/initializers/elasticsearch.rb: if defined?(Rails::Server) Elasticsearch::Model.client = Elasticsearch::Client.new( log: true, host: 'myhost' ) end
which I had hoped would do the trick but it's not enough. My models look like the following (app/models/item.rb): require 'elasticsearch/model' class Item < ActiveRecord::Base include Elasticsearch::Model include Elasticsearch::Model::Callbacks end Item.import(force: true) # auto sync model with elasticsearch
Would I need to include a guard there, too, for the import? Or is there any other easy way to circumvent Elasticsearch? |
| Rails app is deployed and on, but bundle not seeing rails Posted: 26 Jul 2016 04:51 AM PDT I use Rails 4 in my app and am deploying it using Ansible&Capistrano. As an Ansible template I use playbook pretty similar to this one - https://github.com/JohnnyR1co/fashcards/blob/master/config/provision/playbook.yml It installs ruby as well as anything else and After cap production deploy I am able to see app on (I can load some non-db related pages). But when I try to run something like RAILS_ENV=production rails c from the current folder I get The program 'rails' can be found in the following packages: * ruby-railties-3.2 * ruby-railties-4.0 Try: apt-get install <selected package>
Why is this so? App is up and running, so rails seem to be fine. Also when I try to run bundle install I get an error that nokogiri is not installed, despite I installed it manually after deploy. What could be the reason here? I believe problem could be in playbook.ymlfile. Ruby installation is done there and I am not sure how correct is it. |
| Example of something that is not thread-safe in Rails Posted: 26 Jul 2016 05:06 AM PDT I've seen threads like this on thread-safety in Rails and various web pages on the topic, and I'm sure everyone's great at reciting what it is and giving 'tips' on what isn't thread-safe ("class variables!"), but I can never seem to find a clear, simple, complete example of something that is actually not thread-safe in Rails, to the point where I wonder if anyone actually understands it at all. I would be grateful if someone could prove me wrong and give: a clear, simple, complete example of something that is not thread-safe in Rails. It should be clear where the code is (i.e., if it is in the controller, please show it as such) and nothing should be left to the reader's imagination (such as a method that doesn't exist). Also, there shouldn't be any superfluous code or logic. exactly how it would be problematic in the context of two users connecting to the website at the same time, on two different threads. how to rectify the problem. The more significant and Rails-relevant the example, the better, so if you can give an example where one user might see another user's data (or similar), please do so. |
| How to upload multiple images in Rails 4 with Carrierwave - upload does not occur Posted: 26 Jul 2016 04:30 AM PDT I'm working on product catalog - each item (model: Item) has many images (model: ItemImage). For image upload I use Carrierwave gem. After submitting a form with Item attributes I see that all text/select fields works correctly except image ulpoad - I don't see any pictures on my "show" page and no new ItemImages in ActiveRecord. I suppose that form_for generate correctly all queries with item attributes but item_controller don't save data from "item_images_attributes". How can I fix that problem? UPDATE: I missed an error after form submittion - "Failed to manipulate with MiniMagick, maybe it is not an image?
