| How could I use a regex expression in Ruby to ignore html tags? Posted: 26 Sep 2016 08:02 AM PDT I have a Blog ActiveRecord model in a rails application. The body property is text. It includes html tags for images, headings etc.. I want to create a method that takes the first n amount of text of the body to show on the index page as preview text. The problem is my method also grabbed all of the html tags so my method returns a string that looks like this. Here is a picture I am talking about. <img src="path/to/image.png" / > <h1> Nice </h1>
Is there regex solution to ignore all the tags? |
| can't make rails assets pipeline to works? Posted: 26 Sep 2016 07:55 AM PDT i am developing an app in rails with some css and js plugins template, by default we should separate or js and css file into javascript and css folder right? but the problem is my plugins folder structure are quite complex, have a lot of sub folders, so i decided to put all the assets (css, js, images, fonts) into a folder, the problem is everything not working on production mode, the css styles, scripts, images all not loaded, please help. here is my structure : javascripts stylesheets public_assets - img - icon - bg - favicon - images - proteam - png - ualanding - portofolio - fullsize - thumbnail - font - css - js - sass - vendor - ninja-slider - bootstrap - font - css - js - font awesome - css - fonts - less - scss - jquery - magnific-popup - scroolreveal - vid images Static_Dev
FYI i already run rake assets:precompile command i reference my images mostly like these : <img alt="UrbanAce" src="assets/img/logo.png" height="24">
i believe when i run on production mode, the assets path changed, so i changed my image tag to : <%= image_tag "logo.png", { src: "logo.png", height: "24"} %>
the above code did not work, even in development mode. also, what if i need to call some background images from css? something like : .hero { background-image: url("../img/png/UA-Landing/UA-Pattern.png"); background-repeat: repeat-x; background-position: 0 76px; height: 280px; }
i call font like this : @font-face{font-family:FreightSansPro;src:url(../font/FreightSansPro-Light.otf) format("opentype");
how should i replace it? so it will work on production and development mode. many thanks.... |
| ruby-on-rails override state_machine in the inherited class Posted: 26 Sep 2016 07:42 AM PDT I have two ActiveRecord classes: class Gateway::Transaction < ActiveRecord::Base state_machine :initial => :setup do # ... many events.. end end
and an inherited class class Gateway::BetterTransaction < Gateway::Transaction state_machine :initial => :setup do # ... many events ... end end
The problem is that all the events and rules from the base class are still in the inherited class. I looked in the state_machine gem documentation and saw no option of how to modify this behavior - only that if a transition exists (also in the base class) then the state machine will use the first found transition. Is there a way to override the state machine from the base class with a new one? |

| Heroku run rake db:migrate Errno::EISDIR: Is a directory @ io_fillbuf - fd:9 /app/.fog Posted: 26 Sep 2016 07:43 AM PDT Hi all so after pushing my code to Heroku, i am currently unable to run heroku run rake db:migrate and this is the error i am getting. rake aborted Errno::EISDIR: Is a directory @ io_fillbuf - fd:9 /app/.fog
To provide some context, i am using fog-google to support media uploads in production. In config/initializers/fog.rb the code is as follows GoogleStorage = Fog::Storage::Google.new( :google_project => 'XXXX', :google_client_email => 'XXXXX', :google_json_key_location => Rails.root.join('.fog/XXXX'), :google_storage_access_key_id => ENV['GOOGLE_STORAGE_ACCESS_KEY_ID'], :google_storage_secret_access_key => ENV['GOOGLE_STORAGE_SECRET_ACCESS_KEY'] )
My google_json_key_location is saved in a .fog folder. I'm not sure if that's what is causing the error because heroku can't find the file since the .fog folder is not uploaded onto my Git Repo. But i'm not quite sure where else should i be saving my JSON Private Key file as i think it shouldn't be something uploaded onto my git repo? EDIT: I amended the folder from .fog to just fog so now i am able to run heroku run rake db:migrate The problem is that i'm quite sure i shouldn't be saving this file onto my git. What is an alternative solution for saving this file privately and still being able to access it on heroku? All help and advice would be greatly appreciated! Thank you so much! |

| Rails read value of a number_field and display it on page Posted: 26 Sep 2016 06:28 AM PDT My goal is to use coffeescript to read the value from a number_field in the view, send the value to the coontroller and then send the number value from the controller back to the view. In the coffeescript file I use console.log(qty) as a check to see, if coffeescript is able to read the number_field value. This check passes. In the controller I use puts "received #{@n}" and puts "not received" as checks. On page load the else portion should execute, since the .change event has not yet triggered. When the number field is changes the if portion should execute. This test passes correctly. When the number field is changed the correct value for @n is printed to the rails console. This means that the params[:quantity] is received by the controller action. The last step would be for $('#insert-here').load(location.href+" #insert-here") to reload the #insert-here div on the page. To check this I added <%= Time.now %> in the view to see that the timestamp changes. This test passes as well, but <h1><%= @n %></h1> in the view continues to show the number 1. It does not update. How can I fix this? View <%= oi.number_field :quantity, value: 1, class: 'form-control', id: 'quantity-select', min: 1 %> <div class="col-xs-12" id="insert-here"><h1><%= @n %></h1><h2><%= Time.now %></h2></div>
Coffeescript ready = -> $('input[type=number][id=quantity-select]').change -> qty = document.getElementById('quantity-select').value $.ajax complete: (request) -> data: { quantity: qty } console.log(qty) $('#insert-here').load(location.href+" #insert-here") return return $(document).ready(ready)
Controller def show if params[:quantity].present? @n = params[:quantity] puts "received #{@n}" else @n = 1 puts "not received" end end

| Why am I getting sporadic disconnects when using capybara-webkit gem in Rails 4? Posted: 26 Sep 2016 06:37 AM PDT I use the capybara-webkit gem to scrape data from certain pages in my Rails application. I've noticed, what seems to be "random" / "sporadic", that the application will crash with the following error: Capybara::Webkit::ConnectionError: /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/bin/webkit_server failed to start. from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/lib/capybara/webkit/server.rb:56:in `parse_port' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/lib/capybara/webkit/server.rb:42:in `discover_port' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/lib/capybara/webkit/server.rb:26:in `start' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/lib/capybara/webkit/connection.rb:67:in `start_server' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/lib/capybara/webkit/connection.rb:17:in `initialize' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/lib/capybara/webkit/driver.rb:16:in `new' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/lib/capybara/webkit/driver.rb:16:in `initialize' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/lib/capybara/webkit.rb:15:in `new' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-webkit-1.11.1/lib/capybara/webkit.rb:15:in `block in <top (required)>' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-2.7.1/lib/capybara/session.rb:85:in `driver' from /home/daveomcd/.rvm/gems/ruby-2.3.1/gems/capybara-2.7.1/lib/capybara/session.rb:233:in `visit'
It happens even after it's already connected and accessed a website multiple times before. Here's a code snippet of what I'm using currently... if site.url.present? begin # Visit the URL session = Capybara::Session.new(:webkit) session.visit(site.url) # here is where the error occurs... document = Nokogiri::HTML.parse(session.body) # Load configuration options for Development Group roster_table_selector = site.development_group.table_selector header_row_selector = site.development_group.table_header_selector row_selector = site.development_group.table_row_selector row_offset = site.development_group.table_row_selector_offset header_format_type = site.config_header_format_type # Get the Table and Header Row for processing roster_table = document.css(roster_table_selector) header_row = roster_table.css(header_row_selector) header_hash = retrieve_headers(header_row, header_format_type) my_object = process_rows(roster_table, header_hash, site, row_selector, row_offset) rescue ::Capybara::Webkit::ConnectionError => e raise e rescue OpenURI::HTTPError => e if e.message == '404 Not Found' raise "404 Page not found..." else raise e end end end
I've even thought perhaps I don't find out why it's happening necessarily - but just recover when it does. So I was going to do a "retry" in the rescue block for the error but it appears the server is just down - so I get the same result when retrying. Perhaps someone knows of a way I can check if the server is down and restart it then perform a retry? Thanks for the help! |

| Rails: how to display all pending friend requests? Posted: 26 Sep 2016 06:47 AM PDT I'm working on my first Rails project and I have a small problem. I'd really appreciate any help. I want to display all pending friend requests for a current user using each iterator. My controller: class FriendRequestsController < ApplicationController before_action :set_friend_request, except: [:index, :new, :create] def index @incoming = FriendRequest.where(friend: current_user) @outgoing = current_user.friend_requests end def new @friend_request = FriendRequest.new end def create friend = User.find(params[:friend_id]) @friend_request = current_user.friend_requests.new(friend: friend) if @friend_request.save redirect_back(fallback_location: root_path), status: :created, location: @friend_request else render json: @friend_request.errors, status: :unprocessable_entity end end
When I try something like a code below, it kinda works, the conditional statement works as it should, but I know it's a terrible way to make it work, so I'd like to use @incoming since it's defined. <% if FriendRequest.where(friend: current_user).present? %> <% ?.each do |request| %> <li><%= ? %></li> <% end %> <% else %> You don't have any friend requests <% end %>
But when I try something like: <% if @incoming.present? %>
The conditional statement doesn't work properly and there's 'You don't have any friend requests', even though the current user has a pending friend request. I don't exactly get how everything works in RoR yet, so I'd be thankful for an explanation. |

| Rails 5 Rspec receive with ActionController::Params Posted: 26 Sep 2016 06:41 AM PDT I have just upgraded to Rails 5. In my specs I have the following expect(model).to receive(:update).with(foo: 'bar')
But, since params no longer extends Hash but is now ActionController::Parameters the specs are failing because with() is expecting a hash but it is actually ActionController::Parameters Is there a better way of doing the same thing in Rspec such as a different method with_hash? I can get around the issue using expect(model).to receive(:update).with(hash_including(foo: 'bar'))
But that is just checking if the params includes that hash, not checking for an exact match. |

I don't know exactly what's happening, because I can use the code from this new Gem locally but when deployed it don't load, or don't install. Seems that could be a syntax problem searching on Google, but don't know how to make sure because it was a long time ago I haven't added a Gem, so the syntax erro could be so old. Is there some tool to check if there's a syntax error? And I thing it's weird since it's working locally.

| Email - From address is the logged in address and not the address that specified in 'from' attribute Posted: 26 Sep 2016 05:58 AM PDT Below is the code for the mailer which sends the verification email: ApplicationMailer class ApplicationMailer < ActionMailer::Base default from: "from@example.com" layout 'mailer' end
SendVerificationMailer class SendVerificationMailer < ApplicationMailer def send_verification(verification_id) @verification = Verification.find(verification_id) @email = @verification.email @token = @verification.token mail :from => "Support <support@domain.io>", :to => @email, :subject => "User verification code" end end
In production.rb I have configured the action_mailer as follows: # Mailing preferences config.action_mailer.default_url_options = { :host => ENV["HOST_NAME"] } config.action_mailer.delivery_method = :smtp config.action_mailer.smtp_settings = { :enable_starttls_auto => true, :address => ENV["SMTP_ADDRESS"], :port => ENV["SMTP_PORT"], :domain => ENV["SMTP_DOMAIN"], :authentication => :login, :user_name => ENV["EMAIL"], :password => ENV["PASSWORD"] }
I used an account info@domain.io for smtp user_name and password. When I send Email from local machine it is working fine and the from address in the received mail is support@domain.io in both development and production mode. But, when the mail is sent from production machine in AWS the from address displayed as info@domain.io and not support@domain.io what I expect to be.
I am using AWS Elastic Beanstalk for deployment in which I have a web server and a worker, where the worker takes the attributes from SQS queue and send the Email. Can anyone help me in fixing this. Thank you.. |
| Save file name to the db after it's uploaded from the browser and refresh Posted: 26 Sep 2016 07:20 AM PDT I upload file from the browser to S3 (it works): view <form action="<%= @url %>" method="post" enctype="multipart/form-data"> Key to upload: <input type="input" name="key" value="<%= create_filename %> " /><br /> <!-- some other fields --> File: <input type="file" name="file" /> <br /> <input type="submit" name="submit" value="Upload to Amazon S3" onclick="<%= validate_file_and_submit(@filename) %>" />
controller def validate_file_and_submit(filename) new_image = Image.new( post_id: params['post_id'], user_id: current_user.id, filename: filename ) if new_image.save redirect_to post_path(params['id']) end end
I need to save the new filename generated by create_filename to the db Image.filename and also refresh the page after successful upload or display an error if it failed. edit: I'd appreciate if anyone could help or tell me why the question is idiotic instead of -1. Been told I must upload the file from the browser, cant use the backend but must store the name in the db. |
| ruby, enable chat between two users Posted: 26 Sep 2016 04:57 AM PDT I am on RoR and I would like to know if anyone can explain how I can create a system which displays a button for sending a message invitation to an other user. If I havn't send invitation, then the button should be "Send invitation", else the button should be "Remove invitation". I have created a messaging system that allows communication between all users of my website.I also have created an notification system which help them send notification to users. I have a MVC application for my "send_invitation" system but not sure how to create a method which will send notification to other user. And also to ensure that when the user accepts the request, they should be allowed to exchange messages. I want a clarification on the above process. |

| import salesforce database in my rails app Posted: 26 Sep 2016 03:58 AM PDT I created a Rails app with Heroku and i have to import data from Salesforce. I followed guides from the Devcenter Heroku to setup the project but i have no idea about how to use my database in rails heroku config command show my variable DATABASE_URL (I added it to my env).
here my database.yml. I set the same in development and production (I know it's bad) defaul: &default adapter: postgresql encoding: unicode pool: <%= ENV.fetch("RAILS_MAX_THREADS") {5} %> production: <<: *default adapter: postgresql database: <%= ENV['DATABASE_URL'] %> username: postgres password: <%= ENV['DATABASE_PASSWORD'] %> host: localhost
I can access to my database with psql but only with '$DATABASE_URL' in argument. I can't connect to it with '\c' #psql $DATABASE_URL my_db=> \dt salesforce.*
And it display tables from salesforce I selected on Heroku connect. I can also add or remove content. I want to do the same into my app: add or remove something from a HTML form, display content of this db... I'm a beginner with Salesforce and Rails EDIT for Caffein coder: My schema.rb. I may modify it by following some tutorials but i'm not sure at all ActiveRecord::Schema.define(version: 20160923134925) do enable_extension "plpgsql" enable_extension "hstore" create_table "products", force: :cascade do |t| t.string "title" t.integer "price" t.text "description end end

| Error handling to return error object in services Posted: 26 Sep 2016 04:09 AM PDT This is CreateSubscription service class. I put this logic in service because there are api calls and some data insertion occurs. (This is simplified version.) This class is called basically from controller, and I need to handle errors there. However the question is how can I triger errors with user.erros object instead of full_messages, so that I can iterate the errors and create error response with JSON. { "error": "Uuid can't be blank, Name can't be blank, and Email is invalid" } to { "errors": [ { "uuid": [ "can't be blank" ],"name" : ["can't be blank"].. } ] } services/create_subscription.rb class CreateSubscription class UserCreateError < StandardError; end def self.call(plan, user_info:) subscription = nil ActiveRecord::Base.transaction do user = CreateUser.call(user_info) raise UserCreateError.new(user.errors.full_messages.to_sentence) unless user.valid?
service/create_user.rb class CreateUser def self.call(payment_info) uuid = payment_info[:uuid] name = payment_info[:name] email = payment_info[:email] user = User.find_by(uuid: uuid) return user if user.present? user = User.create( uuid: uuid, name: name, email: email ) user end end
UPDATE controller/subscriptions_controller.rb def create # Some logic .... rescue CreateSubscription::UserCreateError => e # TODO: This should be an array, not only each one render json: { error: e.message }, status: :bad_request
