| Deliver later not working in the test environment in Rails 5 Posted: 24 Sep 2016 07:45 AM PDT Basically, with the test config set up exactly how it worked in Rails 4 (delivery method set as test etc), aside from deprecated options which I have replaced, mail only sends with deliver_now, not deliver_later. Deliver_later works in the development environment, even when the config is identical between the two environments. Test environment mailer config: config.action_mailer.delivery_method = :test config.action_mailer.perform_deliveries = true config.action_mailer.perform_caching = false config.action_mailer.raise_delivery_errors = true config.action_mailer.default_url_options = { :host => 'localhost:3000' }

| WebRTC Error: Failed to create remote session description. Called in wrong state Posted: 24 Sep 2016 06:47 AM PDT I am trying to implement a real time audio/video group calls, but for now I want to get it for only two participants. It is not working and I don't understand why :( (actually when I test it with myself with two different accounts at the same time, I see some error messages but it works anyway, but when I test it with a friend in real different networks, the same error messages appear but in this case we can not hear or see each other). I am using Chrome 53 on Linux (Ubuntu 16.04). The error messages are the following, for the peer who sends the offer there are 6 errors in the browser console. 1st: Failed to create remote session description: OperationError: Failed to set remote offer sdp: Called in wrong state: STATE_SENTOFFER
2nd, 3rd, 4th, and 5th: addIceCandidate error: OperationError: Error processing ICE candidate
6th: Failed to set local session description: OperationError: CreateAnswer failed because remote_description is not an offer
And for the peer who receives the offer and sends and answer there is 1 error in the browser console: Failed to create remote session description: OperationError: Failed to set remote answer sdp: Called in wrong state: STATE_INPROGRESS
In case you want to see all the messages in the console, the ones in the peer who sends the offer are here: WebRTC error from offer peer. And the ones in the other peer browser console are here: WebRTC error from answer peer. The code that matters in the the HTML file is the following (there are other files with Javascript code that I will show later): <div class='row'> <div class='col-xs'> <div class='box center-xs middle xs'> <h1>Call CallNameExample</h1> </div> </div> </div> <div class='row'> <div class='col-xs'> <div class='box center-content'> <button class='btn btn-info btn-37 no-padding circle' id='btnChangeCamStatus'> <i class='material-icons' id='iconCamOff'> videocam_off </i> <i class='material-icons hidden' id='iconCamOn'> videocam </i> </button> <button class='btn btn-info btn-37 no-padding circle' id='btnChangeMicStatus'> <i aria-hidden='true' class='fa fa-microphone-slash' id='iconMicOff'></i> <i aria-hidden='true' class='fa fa-microphone hidden' id='iconMicOn'></i> </button> </div> </div> </div> <div class='row'> <div class='col-xs'> <div class='box center-xs middle xs'> <video autoplay height='200px' id='bigRemoteVideo' width='200px'></video> </div> </div> </div> <script> var room = "1" var localVideo = document.getElementById("localVideo") var bigRemoteVideo = document.getElementById("bigRemoteVideo") document.getElementById("btnChangeCamStatus").addEventListener("click", function() { if (localStream.getVideoTracks()[0].enabled) { disableCam() $("#iconCamOff").addClass("hidden") $("#iconCamOn").removeClass("hidden") } else { enableCam() $("#iconCamOff").removeClass("hidden") $("#iconCamOn").addClass("hidden") } }, false); document.getElementById("btnChangeMicStatus").addEventListener("click", function() { if (localStream.getAudioTracks()[0].enabled) { disableMic() $("#iconMicOff").addClass("hidden") $("#iconMicOn").removeClass("hidden") } else { enableMic() $("#iconMicOff").removeClass("hidden") $("#iconMicOn").addClass("hidden") } }, false); function setLocalVideo(stream) { localVideo.src = window.URL.createObjectURL(stream) } function setRemoteVideo(stream) { bigRemoteVideo.src = window.URL.createObjectURL(stream) } localVideo.addEventListener('loadedmetadata', function() { console.log('Local video videoWidth: ' + this.videoWidth + 'px, videoHeight: ' + this.videoHeight + 'px'); }); bigRemoteVideo.addEventListener('loadedmetadata', function() { console.log('Remote video videoWidth: ' + this.videoWidth + 'px, videoHeight: ' + this.videoHeight + 'px'); }); // Starts the party: (function(){ enableUserMedia() window.createOrJoin(room) console.log("Attempted to create or join room: " + room) }()) </script>

And finally the code related to the signaling. But first I want to clarify I am doing this website with Rails 5 and the signaling with WebSockets via ActionCable, so the CoffeeScript file (the client side) for the channel is this one: window.createOrJoin = (roomID) -> App.call = App.cable.subscriptions.create { channel: "CallChannel", room: roomID }, connected: -> # Called when the subscription is ready for use on the server createPeerConnection() disconnected: -> # Called when the subscription has been terminated by the server received: (data) -> # Called when there's incoming data on the websocket for this channel if (data["kindOfData"] == "created") console.log('Created room ' + data["room"]) window.isInitiator = true # ESTO ME SIRVE SOLO PARA 2 PERSONAS!! # CREO QUE YA NI LO USO attachLocalMedia() else if (data["kindOfData"] == "full") console.log('Room ' + data["room"] + ' is full') else if (data["kindOfData"] == "join") console.log('Another peer made a request to join room ' + data["room"]) console.log('This peer is the initiator of room ' + data["room"] + '!') window.justJoinedRoom = false else if (data["kindOfData"] == "joined") console.log('joined: ' + data["room"]) window.justJoinedRoom = true attachLocalMedia() else if (data["kindOfData"] == "log") console.log(data["info"]) else if (data["kindOfData"] == "message") # This client receives a message console.log("Client received message: " + JSON.stringify(data["message"])); if (data["message"] == "bye") handleRemoteHangup() else if (data["message"]["type"] == "offer") handleReceivedOffer(data["message"]) # obj with "type" and "sdp" else if (data["message"]["type"] == "answer") handleReceivedAnswer(data["message"]) # obj with "type" and "sdp" else if (data["message"]["type"] == "candidate") handleReceivedCandidate(data["message"]["label"], data["message"]["candidate"]) message: (data) -> console.log("Client sending message: " + JSON.stringify(data)); @perform "message", {message: data, room: roomID}
And the Ruby one (the server side): class CallChannel < ApplicationCable::Channel def subscribed # Action automatically called when a client is subscribed to the channel stream_from "calls" # calls is a channel in common for everyone # ONLY FOR TESTING!!! stream_from "calls_room#{params[:room]}_person#{current_user.id}" @@hashUsersByRoom ||= Hash.new() # { |h,k| h[k] = Set.new } @@hashRoomsByUser ||= Hash.new() # { |h,k| h[k] = Set.new } result = createOrJoin(params[:room]) end def unsubscribed # Any cleanup needed when channel is unsubscribed end def message(data) if data["message"].eql?

Searching on the Internet I saw people with similar problems but each one was for a different reason and none of them was useful for my situation, but I saw somewhere that "STATE_INPROGRESS" means "Offer/answer exchange completed" so from that I can't understand if the offer/answer exchange was completed... why it is not working when I try to use it with a friend? and why is it trying to set more remote session descriptions in that case (when the offer/answer exchange is supposed to be completed)? So basically my main question is: what is going on and how can I solve it? If you reached this part of the question, thank you, I appreciate it! :) |

| How to use yield with dashboard sidebar to show contents on same page Posted: 24 Sep 2016 05:48 AM PDT I have a rails app with a functionality quite similar to yelp with a dashboard for customers where they can edit their place but also change their acccount settings, etc. A customer can only have one place for now. I've created a dashboard controller, views with a partial for the sidebar and everything is working so far but my problem is that when clicking on a link in the sidebar it yields to the application.html.erb. I want to yield everything from the sidebar to the main part of the dashboard/index.html.erb So my question is how do I yield the things I click in my sidebar to the part on the right next to the sidebar on the page. Basically the functionality is like a navbar on top (only for logged in customers) but I get confused with two yields. I tried "content_for" and <%= yield :sidebar %> but didn't figure out how to get it working yet. Also I am using devise with a user and customer model which share the views and have the functionality for the customer to edit his user account in the dashboard sidebar which might cause a problem with "content_for"? Please note that I am still learning ruby on rails and am very happy for any kind of input! dashboard_controller.rb def index @place = Place.where(customer_id: current_customer.id).first end
dashboard/index.html.erb <div class="content"> <div class="sidebar"> <%= render 'dashboard/sidebar' %> </div> <div class="main"> <%= yield %> </div> </div>
application.html.erb <body> <%= render 'layouts/shared/header' unless @disable_navbar %> <%= yield %> <%= render 'layouts/shared/footer' unless @disable_footer %> </body>

| Setting up ssl dns for Multiple domains for Rails and Heroku Posted: 24 Sep 2016 04:11 AM PDT I have a Rails application hosted on Heroku. For purposes of this example, let's assume the custom domain that I own is foo.com. I need to set up ssl for: - foo.com
- *.foo.com
- staging.foo.com
- *.staging.foo.com
I have used Cloudflare in the past as it provides free ssl and dns setup. It is my understanding that Cloudflare does not support 2 level subdomains i.e. *.staging.foo.com will not be covered by my dns and page rules. Am I correct in my understanding of Cloudflare? Currently my setup looks like this: - CNAME: foo.com -> foo.herokuapp.com
- CNAME: staging.foo.com -> staging_foo.herokuapp.com
- CNAME: *.staging.foo.com -> staging.foo.com
Up next I have some page rules setup: - http://foo.com/* -> Always route to HTTPS
- http://staging.foo.com/* -> Always route to HTTPS
- http://*staging.foo.com/* -> Always route to HTTPS
This seems to work for everything except the 2 level subdomain. Am I doing something incorrectly or is this a Cloudflare feature limitation? Are there any other services that I can make use of that offers low cost SSL(Wildcard) and DNS management? The budget is quite tight. Thanks |

| polygon 'contains' and other operations on geometries not supported Posted: 24 Sep 2016 04:36 AM PDT I'm quite new to postgis and rgeo. I suspect I may be tackling things in the wrong way but I have been a bit surprised to find out a few operations, in particular contains & within, aren't possible on spherical based objects. I have a bunch of geographically distributed objects which I would like to group together based on things like postcode. For each of of these groupings I have a boundary and I would like to check if an object is inside that boundary and also check if one boundary is inside another. I'm using rails and this is the migration used to set up my collection model class CreateGeoCollectionDefinition < ActiveRecord::Migration[5.0] def change create_table :geo_collection_definitions do |t| t.string :name t.string :geo_place_id t.string :geo_place_types, array: true, default: [] t.st_polygon :boundary, geographic: true t.jsonb :boundary_json t.st_point :latlng, geographic: true end end end
Currently the boundary is coming from a google reverse geocode lookup. The NorthEast and SouthWest bounding box coordinates are passed into this method on object creation GEO_FACTORY = RGeo::Geographic.spherical_factory(srid: 4326) def self.createBoundary(pointOne, pointTwo) point1 = GEO_FACTORY.point(pointOne['lat'], pointOne['lng']) point2 = GEO_FACTORY.point(pointTwo['lat'], pointTwo['lng']) boundingBox = RGeo::Cartesian::BoundingBox.create_from_points(point1, point2).to_geometry boundingBox end
I have written a few of specs to check that everything is behaving in the way that I expect. The simple distance based tests all pass as expected but there are issues with the ones used to test the boundary functionality. I run into the following # ------------------ # --- Caused by: --- # PG::UndefinedFunction: # ERROR: function st_contains(geography, geography) does not exist # LINE 1: ...COUNT(*) FROM "geo_collection_definitions" WHERE (ST_Contain... # ^ # HINT: No function matches the given name and argument types. You might need to add explicit type casts.
When I try and run a query like (I know its a bit of a silly one) GeoCollectionDefinition.where("ST_Contains(boundary, boundary)")
or if I try using the rgeo object directly it "should be possible to test is points belong in GeoCollection.boundary" do factory = RGeo::Geographic.spherical_factory(srid: 4326) externalPoint = factory.point(EmptyGeocodeLatLag['lng'], EmptyGeocodeLatLag['lat']) expect(someplace_def.boundary.contains?(someplace_def.latlng)).to be_truthy expect(someplace_def.boundary.contains?(externalPoint)).to be_falsy end
I get RGeo::Error::UnsupportedOperation: Method Geometry#contains? not defined.
Digging around I found this rgeo issue and other evidence that these operations are just not supported for spherical factory based objects I'm just wondering; - Is this definitely the case
- Modelling the boundary and the location of objects in the way described in my migration seems to make sense to me but I'm guessing I'm wrong about that?
- How should I go about finding out if a bunch of points are inside a polygon using postgis, rgeo and the active record adaptor?
- Is it possible to check if one polygon is inside another?

After that I checked my Cpanel and saw that my app now uses maximum proceses 40/40 and CPU usage is up. Those things never happened before (at leat I didn't saw it)

| Filter ActiveRecord records by nested resource logic - Rails Posted: 24 Sep 2016 03:17 AM PDT I'm building a task list app in rails which allows user to create task lists which contain tasks. I am trying set up filtering so I can display only task lists that have all of it's tasks marked as complete. Currently: List model: class List < ActiveRecord::Base belongs_to :user has_many :tasks end
Task model: class Task < ActiveRecord::Base belongs_to :list def completed? !completed_at.blank? end end
As I understand it, ActiveRecord's .where query method only looks at at that model's fields and it's value (e.g: @lists.where(name: "List Name")) Does anyone know a way of doing something similar to the pseudo code below: @completed_lists = @lists.where(list.tasks.completed.count == list.tasks.count)

| Rails 5: find all Users who belong to Companies, which belong to current_user Posted: 23 Sep 2016 11:41 PM PDT In my app User can have many Companies and vice versa. In Accounts table id of User and id of its Company is stored. I want to find all Users who belong to Companies, which belong to current_user. Let's assume that the current_user is like master User (not Admin, as that would be system Admin) of those companies. How do I do this? My guess is to do it with Arel, but then how should it look in Model, Controller, View? Many thanks for any help. I'm on Rails 5. models/user.rb class User < ApplicationRecord has_many :accounts, dependent: :destroy has_many :companies, through: :accounts
models/account.rb class Account < ApplicationRecord belongs_to :company belongs_to :user accepts_nested_attributes_for :company, :user
models/company.rb class Company < ApplicationRecord has_many :accounts, dependent: :destroy has_many :users, through: :accounts accepts_nested_attributes_for :accounts, :users
My schema.rb looks like this: create_table "accounts", force: :cascade do |t| t.integer "company_id" t.integer "user_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.index ["company_id"], name: "index_accounts_on_company_id" t.index ["user_id"], name: "index_accounts_on_user_id" end create_table "companies", force: :cascade do |t| t.string "name" t.string "legal_name" t.string "reg_number" t.string "address" t.string "bank_acc" t.string "description" t.string "website" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.integer "role", default: 0 t.integer "currency", default: 0 end create_table "users", force: :cascade do |t| t.string "name" t.string "email" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.string "password_digest" t.string "remember_digest" t.boolean "admin", default: false t.index ["email"], name: "index_users_on_email", unique: true end

| Rails/Postgres - change default time in Time class Posted: 24 Sep 2016 12:54 AM PDT In my view, I will be ordering a list of items by their start_time. There are instances, however, where there might be a start_time of 1:00 AM (the following day) that should show up as after a start_time of 11:00 PM (previous day). Since the Time class stores a default date of 2001-01-01, it considers an entry of 1:00 AM to be on 2001-01-01, not 2001-01-02. Thus, my question is, is there a way to change the default date in the Time class? I suppose an obvious solution would be to instead store the start and end times in a DateTime class and enter a corresponding date. For this application, however, it is customary to refer to a start time of 1:00 AM as "belonging to" the previous day and would thus be confusing to enter the following day's date. (E.g. When attending your favorite band's concert on a Friday night, their set might start at 12:30 am Saturday morning, but you would still consider the concert to be on a Friday night). Thank you for your help. |
| Devise Sign-Up Route End of File Reached Error Posted: 23 Sep 2016 09:31 PM PDT I've searched all over the internet for an answer to this error, but nothing seems to address it directly or effectively. I am using Devise in a Rails application and whenever I go to the users/sign_up page and submit the data, it will not submit properly and Rails gives me the error: "EOFError at /users end of file reached" Rails also includes this trace: rbuf_fill/Users/john/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/net/protocol.rb BUFSIZE = 1024 * 16 def rbuf_fill begin @rbuf << @io.read_nonblock(BUFSIZE) rescue IO::WaitReadable if IO.select([@io], nil, nil, @read_timeout) retry else raise Net::ReadTimeout
Which I have had no luck following. From other posts, I believe something may be wrong with the mailer setup, but I've tried every solution recommended and I'm still getting this error. Currently, I have config.mailer_sender = SUPPORT_EMAIL setup in the config/initializers/devise.rb file. I would greatly appreciate any suggestions anyone has, as I've spent a ton of time on this with no luck. |
