| Rails 4: EOFError: end of file reached following any email in DEVELOPMENT only Posted: 11 Apr 2016 07:13 AM PDT I have rails app which uses devise ofr authentication and sidekiq for background email jobs. All of a sudden, in development only, I am getting the following error associated with an attempt to send an email from the app (e.g. devise forgotten password) EOFError: end of file reached
Strangely the app in production works (heroku set up using sendgrid). I haven't changed any of my development email settings.... ActionMailer::Base.default :from => 'slfwalsh@gmail.com' config.action_mailer.delivery_method = :smtp config.action_mailer.perform_deliveries = true config.action_mailer.raise_delivery_errors = true config.action_mailer.smtp_settings = { :address => "smtp.gmail.com", :port => 587, :domain => '@gmail.com', :user_name => "xxxxx@gmail.com", :password => "xxxxxxxx", :authentication => 'plain', :enable_starttls_auto => true } config.action_mailer.default_url_options = { :host => 'localhost:3000' }
I can't find anything to address this online. Also I note that ALL my apps in development, using similar settings are throwing the same error. I tried a different email address and password (again gmail) and no luck.... |
| Don't Duplicate Entries Rails Posted: 11 Apr 2016 07:04 AM PDT I'm currently calling this every 3hrs, but it's storing duplicates of the same data. I've tried a few methods here on Stackoverflow but none of them seem to be actually working. def fetch_data response = self.class.get("/tap-2_JD7rkZupwNmg91im5G/last_ready_run/data?format=json") @elements = response.parsed_response["link"] # To access the image src's: image_srcs = @elements.collect { |e| e['image'] } image_srcs.each do |image| self.entries.create(image: image) end end
Is there a way to check against each 'image' string that it collects and make sure it's not a duplicate before it inserts a new entry into the database Thanks |
| conditional scope based on either two fields being true but not both Posted: 11 Apr 2016 06:57 AM PDT I am needing to create a scope that checks for either two fields on the model being true, however it shouldn't include records where both are true, only ones where either of them are. I hope that makes sense. I am using Rails 3.2 and Mongo 3. Can any recommend a way to achieve this? My first attempt has been scope :with_training_complete, where( :volunteer_training_completed => true ).or(:face_to_face_training_attended => true)
but that brings back only records where both are true. any help would be much appreciated. |
| Rspec - user_path(user) is missing required keys: [:id] Posted: 11 Apr 2016 06:48 AM PDT In the browser everything works fine, but the Rspec test fail with this message: ActionController::UrlGenerationError: No route matches {:action=>"show", :controller=>"users", :id=>nil, :locale=>#<User id: 1, email: [...] } missing required keys: [:id] My failing test: subject {create(:client)} #from factory_girl visit user_path(subject)
For the test to pass, I have to explicitly write the id: visit user_path(id: subject) The strange thing is that it was going fine before, until I ran a bundle update for railties etc. This problem has appeared for my other models as well (Profile, Job, etc). I failed at finding a solution, any help would be very appreciated. |

My site has a form which allows user to select a language and it will display all object whose "languages" includes that language. How to design my controller and view to do that?

| this.setState not re-rendering view ReactJS and Ruby on Rails Posted: 11 Apr 2016 06:25 AM PDT I have a rails app with two reactJS components (not parent/child) that are currently communicating through a global events Pub/Sub system.

| Rails - Unable to access parameters in controller Posted: 11 Apr 2016 06:05 AM PDT I have a Restaurant, Cart, and a User model. I would like to be redirected to a Cart form when entering a restaurant. This form will ask me for a table number and, thereafter, create a cart for the current user. However, when submitting the form I get a problem with the passed parameters Couldn't find Restaurant with 'id'=
I suppose they are not in the white list but I cannot find how to allow them... I will be thankful for any suggestions! The passed params: {"utf8"=>"✓", "authenticity_token"=>"*****", "cart"=>{"restaurant_id"=>"1", "table_id"=>"4"}, "commit"=>"Create Cart", "user_id"=>"1"}
I am passing the restaurant_id with a hidden field and the table with an input <%= f.hidden_field :restaurant_id, value: params[:restaurant_id] %> <%= f.input :table_id %>
In the cart controller: def create @restaurant = Restaurant.find(params[:restaurant_id]) @table = @restaurant.tables.find(params[:table_id]) @cart = current_user.carts.new(cart_params) ... end .... def cart_params params.require(:cart).permit(:restaurant_id, :table_id) end

| $("form").submit(function() { Not working in Firefox Posted: 11 Apr 2016 06:36 AM PDT $("form").submit(function() { if ($("#content") != null) { $("#content").replaceWith('<div id="page-loader" class="fade in"><span class="spinner"></span><span class="spinner-text center">We are running as fast as our little ninja feet can go...</span></div>'); } return true; });
The above works fine on Chrome but does not work on Firefox. Not sure why but in Firefox the form is not actually submitted. The div replace works but no love on the submit, the page just stays idle. The intent here is to capture a submit of any form and throw a spinner (CSS not an image) onto the page until the post / put is returned and the spinner is wiped out by the actual content div on the page reload (non ajax). Before: 
After: 
Code Removed (the post now appears): 
<form accept-charset="UTF-8" action="/users/sign_in" class="new_user" id="new_user" method="post" role="form">
<!-- begin row --> <div class="row"> <!-- begin col-12 --> <div class="col-lg-6"> <div class="form-group"><label class="sr-only control-label" for="user_email">Email</label><input autofocus="autofocus" class="form-control" id="user_email" name="user[email]" placeholder="E-mail" type="email" value="" /></div> </div> <div class="col-lg-6"> <div class="form-group"><label class="sr-only control-label" for="user_password">Password</label><input class="form-control" id="user_password" name="user[password]" placeholder="Password" type="password" /></div> </div> </div> <!-- end row --> <!-- begin row --> <div class="row"> <!-- begin col-12 --> <div class="col-md-12 center"> </br> </div> </div> <!-- end row --> <!-- begin row --> <div class="row"> <!-- begin col-12 --> <div class="col-md-12 center"> <input class="btn" name="commit" type="submit" value="Sign in" /> <div class="m-t-20"> <a href="/users/password/new">Forgot your password?</a><br/> <a href="/users/confirmation/new">Didn't receive confirmation instructions?</a><br/> <a href="/users/unlock/new">Didn't receive unlock instructions?</a><br/> </div> </div> </div> <!-- end row -->
<script> $(document).ready(function () { App.init(); $("form").submit(function(){ if ($("#content") != null) { $("#content").replaceWith('<div id="page-loader" class="fade in"><span class="spinner"></span><span class="spinner-text center">We are running as fast as our little ninja feet can go...</span></div>'); } return true; alert("Submitted"); }); }); $(function () { var hash = window.location.hash; hash && $('ul.nav a[href="' + hash + '"]').tab('show'); });
UPDATE: Ok so i am an idiot but for some reason this didn't cross my mind. What is happening is that the #content div includes the form i am replacing. So the mystery to me is why that worked in Chrome / IE and not in Firefox? If i use the following it works but i get some dangling form elements: $("form").submit(function(){ if ($("#content") != null) { $("#content").append('<div id="page-loader" class="fade in"><span class="spinner"></span><span class="spinner-text center">We are running as fast as our little ninja feet can go...</span></div>'); } return true; });

| How to store and use algorithms? Posted: 11 Apr 2016 06:29 AM PDT - I have a Rails app that displays transportation prices of companies (think e.g. momondo.com).
- Those companies are 'created' using the same data model for all of them. Every company has its unique way to calculate a price.
I have to implement different algorithms for every single one. In some cases an 'algorithm' could just be a lookup in a table, in other cases it's a math formula. So, what kind of data model is the most appropriate here? Thanks in advance |

| calculate score if something true Posted: 11 Apr 2016 04:34 AM PDT I have an application where i take in some data from a user, everything is working fine. I am trying to build a score in the model where if some data is present the score goes up, and i am trying something like this: def score score = 0 if self.moving = true score += 5 end end
Here is my form and the 'moving' column is a boolean: <div class="field"> <%= f.select :moving, [['Yes', true], ['No',false]], {}, :class => 'form-control' %> </div>
What happens is when I try this, when it is true 'yes' the score has 5 added but if i change it to false, I would like the score to go back down to the original score which has been built. Also the score should be stored in a column which has been created in the database, i tried using self.score but it does not seem to work? thanks for the help in advance. |
| Access Doorkeeper from action Rails Controller Posted: 11 Apr 2016 04:52 AM PDT Is there any chance to access authenticate Doorkeeper method from a rails action controller? I would like to skip authentication just for one of my actions('show') but if a specific condition aapplies I want to call the apiauthenticate method to do its job. So in the action 'show', first of all I check a condition, and if does not apply, then I need to activate the api_authenticate. I'm launching a test that should call api_authenticate and stop it there. But for some reason it keeps going on and it does not stop. This is the code of my controller skip_before_action :api_authenticate, only: :show def show param! :id, String, required: true post = Services::Posts.find(params[:id]) if post.public @post = post @user_id = nil else api_authenticate ap "it shouldnt get here if user is not logged in" user = current_resource_owner @post = Services::Posts.show(params[:id], user) @user_id = user.identity rescue nil end end #more actions....
And this is the api_controller.rb where I have the authenticate method class ApiController < ApplicationController protect_from_forgery with: :null_session # Check the user is authenticated before_action :api_authenticate rescue_from ActionController::RoutingError, :with => :route_error rescue_from ::AbstractController::ActionNotFound, :with => :action_error rescue_from Exception, :with => :base_error if Rails.env.production? def api_authenticate doorkeeper_authorize!() end end

| Show time instead of value in chartkick column_chart Posted: 11 Apr 2016 04:57 AM PDT In context of the snippet below is it possible to calculate the chart based on the values but write a custom function that changes these values to a string representation? For example, if i want to change value from seconds into a formatted time string like this: "00:01:11" would be shown instead of the value 71. data = {"Training" => 1}, "Game" => 2} column_chart [{name: "Goals", data: data}]
"Training" would be "00:00:01" and "Game" would be "00:00:02" and the y axis would have changed according to this as well. If it is hard or not possible how else would you recommend doing this? |
| Update two components no relationship Ruby on Rails & ReactJS Posted: 11 Apr 2016 05:01 AM PDT I have a working app using Ruby on Rails and ReactJS which has four components: - ProductContainer

| joins() and where() request on association with custom table name Posted: 11 Apr 2016 06:28 AM PDT I have two models Album.rb class Album < ActiveRecord::Base has_many :tracks self.table_name = 'prefix_album' end
Track.rb class Track < ActiveRecord::Base belongs_to :album self.table_name = 'prefix_track' end
Now, because reasons, the table names are prefixed, so I have prefix_album and prefix_track tables in my database. For basic use, it works fine. Now the problem with the following query : Album.joins(:tracks).where(tracks: { id: [10, 15] })
Results in the following SQL : SELECT * FROM "prefix_albums" INNER JOIN "prefix_tracks" ON "prefix_tracks"."album_id" = "prefix_albums"."id" WHERE "tracks"."id" IN (10, 15)
Which fails because WHERE "tracks"."id" should be WHERE "prefix_tracks"."id". Any idea why active_record is able to get the correct table name for .joins(:tracks) but not for .where(tracks: {}) ? Anyway I have figured this workout : Album.joins(:tracks).merge(Track.where(id: [10,15])) which gives the same result and works. But I would like to know why the former didn't work |
| is there a way to re-render? Posted: 11 Apr 2016 05:17 AM PDT I have written an API in which I am rescuing from all StandardError. Incase of any StandardError, I send an exception email and render json with error message. This works great except when the exception is raised from views (i am using jbuilder for json responses). As then when I render json with error message, it raises double render exception cause render has already been called in controller.

| How can a gem (unintentionally) change the migrations path? Posted: 11 Apr 2016 03:46 AM PDT I wrote a Gem (https://github.com/absolutedevops/civo) which is a simple Rails Engine containing a few API accessing models. However, when I include it in a Rails project, any generators create their files under the Gem's source code not the project's. I can't see anything I'm doing in the Gem that would cause this. It's repeatable (it's happening in two projects at my company and I can reproduce it with a minimal set of steps below). Can anyone tell me how I've managed this?

| Gettext program Posted: 11 Apr 2016 06:38 AM PDT Given the phrase: "You've successfully donated €10 to Doctors of the World"
I wanted to dynamically generate this text for different amounts and charity names, which i did using _("You've donated %{amount} to %{charity_name}")
Where charity_name comes from a list of possible charities and each charity is a hash with data about the charity. I'm not a french speaker and only learnt basic french in school but the problem with doing this (which is probably immediately obvious to any speaker of a language with gendered articles) is that the "to" part of the translation can take various forms a la, au, a'l or aux depending on the noun. eg "Vous souhaitez donner 10€ aux Médecins du Monde" What is the best way to handle this using gettext, given that this will need to be scaled to other languages? There are only a few cases where this will need to be done because most cases of dynamic text (99%+ can be handled fine with parameters. I've thought of 3 ways to do this: 1) Have highly dynamical text such as this generated from a function, one per message per language as necessary. The function accepts an amount and charity name as a parameter and returns the translated text. 2) Manually add a translation for "to " for each charity and use that in place of %{charity_name} and then get the translation from the po file. 3) Add an entry in each charity hash specifying the form of the "to " eg the hash for les Médecins du Monde would also store aux Médecins du Monde. Are any of these methods viable or is there a better alternative I'm not thinking off? |
