| Rails ancestry form outside new Posted: 02 Jul 2016 07:04 AM PDT I am working on adding nested comments with ancestry, and In Rails cast they created new for with: def new @message = Message.new(:parent_id => params[:parent_id]) end
In controller and simple form with the addition of: <%= f.hidden_field :parent_id %>. Trying to achive this result outside of new action (home method) I added form this way: <%= form_for [current_user, post, Comment.new(parent_id: comment.id)], html: { multipart: true }, remote: true do |f| %>
But I have a feeling this is not a way it should be (but it works). Do You have any suggestions or is it ok the way it is? |
| Delaying the toggling action of show/hide until the search is in progress using javascript in rails application Posted: 02 Jul 2016 07:25 AM PDT I would like to wait for javascript hide function until my searches are done so that I could make further searches from thereon.

| Rails Serializer not returning valid JSON (keys not returned in quotes) Posted: 02 Jul 2016 06:40 AM PDT Am having some trouble with a Rails Serializer in an API only app. The app is returning a javascript object where the keys are not enclosed in double quotation marks. Of note, the source API is returning a javascript object with keys not surrounded by quotes. I've found two posts that seem to be related. The second answer here notes that if you receive an object that's not a string, you don't need to parse it, so I guess that's what's going on here, but I can't figure out what to use in place of JSON.parse response in my model. Another related post here; as suggested there, I've tried return JSON(response) instead of JSON.parse response, which also did not produce valid JSON. I see I can remove the each_serializer: KoboApiSerializer line in my Controller, and have tried doing that with the `return JSON(response) line in the Model. Any suggestions on what I should do to produce a valid JSON result would be appreciated. Model, Controller, returned JSON, and source JSON returned from API below. I also have included what is puts'd out to my terminal via the line in my controller. Thanks in advance. Model: class KoboApi < ActiveRecord::Base require 'rest_client' USERNAME = ENV['KOBO_API_USER'] PASSWORD = ENV['KOBO_API_PWD'] SURVEY = ENV['KOBO_API_SURVEY'] API_BASE_URL = ENV['API_BASE_URL'] def self.get_api_info uri = "#{API_BASE_URL}/data/#{SURVEY}?format=json" rest_resource = RestClient::Resource.new(uri, USERNAME, PASSWORD) response = rest_resource.get JSON.parse response end end
Controller: class KoboDataController < ApplicationController def index @kobo_info = KoboApi.get_api_info puts "@kobo_info: #{@kobo_info.inspect}" #values for this returned below. this shows keys surround with quotes. @kobo_info.each do |kobo_info| #some records have NULL for the month_and_year date field. this if then statement date = if kobo_info['month_and_year'] Date.parse(kobo_info['month_and_year']) else nil end KoboApi.where(lemurs_quantity: kobo_info['lemurs_quantity'], month_and_year: date, lemur_category: kobo_info['lemur_category'], location_admin1: kobo_info['location_admin1'], location_admin2: kobo_info['location_admin2']).first_or_create end render( json.KoboApi.all, each_serializer: KoboApiSerializer ) end end
example of object returned from my Rails API app A serializer is in place (here "kobo_data"), so objects are grouped under that. Am including an example object from those returned - note that the object here doesn't necessarily match those I've posted from source API or from console - am including it to show that keys are not enclosed in quotations. { kobo_data: [ { lemurs_quantity: 20, month_and_year: "2016-03-01", lemur_category: "indri", location_admin1: "toliara", location_admin2: "androy" } ] }
example of source json from API: One object (of the many) returned from the source API. Values here don't match values those above or below - am just including to show that keys are not enclosed in double quotations. [ { location_admin1: "fianarantsoa", location_admin2: "atsimo-atsinanana", lemurs_quantity: "5", month_and_year: "2016-01-01", lemur_category: "brown_lemur", }, ]
Putsing it to the terminal.... Values puts'ed out to my terminal via the line in my controller show that it appears to be a valid JSON object, with keys in quotations. As above, the values here do not match the values from my source data - this is just to show that returned values here are enclosed in quotations. Processing by KoboDataController#index as HTML @kobo_info: [{"location_admin1"=>"fianarantsoa", "location_admin2"=>"atsimo-atsinanana","lemurs_quantity"=>"5", "month_and_year"=>"2016-01-01","lemur_category"=>"brown_lemur"} KoboApi Load (0.3ms) SELECT "kobo_apis".* FROM "kobo_apis" WHERE "kobo_apis"."lemurs_quantity" = $1 AND "kobo_apis"."month_and_year" = $2 AND "kobo_apis"."lemur_category" = $3 AND "kobo_apis"."location_admin1" = $4 AND "kobo_apis"."location_admin2" = $5 ORDER BY "kobo_apis"."id" ASC LIMIT 1 [["lemurs_quantity", 5], ["month_and_year", "2016-01-01"], ["lemur_category", "brown_lemur"], ["location_admin1", "fianarantsoa"], ["location_admin2", "atsimo-atsinanana"]]

| Finding Post which don't belong to Author in Rails Posted: 02 Jul 2016 06:33 AM PDT Suppose I have a Post Model like this: class Post < ActiveRecord::Base belongs_to :user end
And the User model looks like this class User < ActiveRecord::Base has_many :posts, dependent: :destroy # I have used devise gem for User management devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :authentication_keys => [:login] end
Then Lets Say X and Y And Z created a Post using their accounts. If X is logged in I can clearly show his Post in Views by just doing this: current_user.post
But for some reason I also want the post which don't belongs to X or lets say arbitrary user?? Is there some way where i can take current_user object and pass some method or something like that?? I simply mean i want to get a post except than a particular user or for example current_user (user who is logged in) Thanks |
| Calling REST APIs without blocking, from Rails application Posted: 02 Jul 2016 05:37 AM PDT I have integrated EventMachine with my Rails application, primarily to use ruby amqp for loosely-coupled interactions between services. But now I figure that I need to make some REST API calls in the context of message callbacks and these cannot be blocking either. I set up EventMachine event loop in a separate thread, and create my AMQP exchanges / queues within it, in a script placed under config/initializers based on this post. But how do I call REST APIs using em-http-request libraries from all over the application - because I cannot add them in EM's run block. |
| How to prevent duplicate records being created, but all other before_create methods to run? Posted: 02 Jul 2016 07:06 AM PDT A Rails app has an Event and Vote model. Events should be unique. If a User attempts to create an Event that already exists, save should be prevented, and instead a Vote should be created for the existing Event. I can prevent the Event from being saved using a custom validation or a before_create action. However, this also prevents the create_vote_on_existing_event method from being run. Is there a way to selectively run methods when before_create returns false? My models look something like this class Event has_many :votes before_create :check_event_is_unique private def check_event_is_unique if Event.where( attributes_to_match).any? errors.add(:base, :duplicate) create_vote_on_existing_event return false end end def create_vote_on_existing_event event = Event.where( attributes_to_match).last self.user.vote_on event end end class Vote belongs_to :event end

| How to invalidate all sessions after user log out in Rails? Posted: 02 Jul 2016 03:51 AM PDT I am new to Rails and I am following Michael Hartl's Rails Tutorial, so my code is mostly borrowed from there. Here is the scenario: I log onto my site using Computer A. Then I log onto the site using the same user id using Computer B. When I log out of the site using Computer A, Computer B remains logged in and can still perform actions. For security reasons, I would like Computer B to be forced to login again when Computer A has logged out. Is there an easy way to invalidate all sessions for a given user upon log out? If you have some sample code that would be very much appreciated. I also read that it is best practice to use reset_session on log out. However, I had trouble determining whether you should use reset_session before or after logging out the user? This is from my Sessions Controller: def destroy log_out if logged_in? # Reset session to prevent session fixation vulnerability reset_session flash[:info] = "You are now logged out" redirect_to root_url end
This is from my Sessions Helper: # Forgets a persistent session def forget(user) user.forget cookies.delete(:user_id) cookies.delete(:remember_token) end # Logs out the current user def log_out forget(current_user) session.delete(:user_id) @current_user = nil end

| Creating custom getters and setters dynamically under STI in Rails Posted: 02 Jul 2016 03:07 AM PDT I am relatively new to meta programming and I am trying to define getters and setters in children models under a single table inheritance, like so: # app/models/player.rb class Player < ActiveRecord::Base serialize :equipments protected # Define getters for setters for individual sports def attr_equipments(*attributes) attributes.each do |attribute| define_singleton_method(attribute) do self.equipments[attribute.to_sym] end define_singleton_method("#{attribute}=") do |value| self.equipments[attribute.to_sym] = value end end end end # app/models/baseball_player.rb class BaseballPlayer < Player after_initialize do attr_equipments :bat, :glove end end

| Rspec expect not working and getting success Posted: 02 Jul 2016 04:07 AM PDT I wrote the following code: require_relative '../ticket' describe Ticket do before do @ticket = Ticket.new() end # context "check_ticket" do # it 'check_a_ticket' do # @ticket.stub(:gets) {"quit"} # expect(@ticket.show_tickets(1)).to be_present # end # end # context "check_tickets" do # it 'check_tickets' do # t@icket.stub(:gets) {"menu"} # expect(@ticket.ticket_viewer(1)).to be_present # end # end context "exit" do it 'check_exit' do result = @ticket.ticket_viewer("quit") expect(result).to include("Thanks") end end end
When I try to execute, expect(result).to eq("something")
does not work. The case is passed no matter what the value is in eg("something"). Help please. |
| Simplest Way to Serve Files - Ruby on Rails Posted: 01 Jul 2016 10:41 PM PDT What's the simplest way to serve files in Rails? By this I mean: I'd like to go to, say, http://myserver.com/assets/arbitraryfile.arbitraryformat and have it just load arbitraryfile.arbitraryformat in the browser, letting the browser decide whether to download it or display it or whatever else. (In particular I plan to make a bookmarklet that invokes a *.js file from the server, which in turn loads a *.css file and downloads a font *.tty file from the same.) Currently I've got an assets resources routing to an assets#show action, but I'm not at all sure how to code my show. |
| How to redirect to www.example.com/products from example.com/products in Rails 2.3.3 Posted: 01 Jul 2016 07:54 PM PDT I have successfully used code to redirect my application from example.com to www.example.com I use the following: class ApplicationController < ActionController::Base before_filter :ensure_domain APP_DOMAIN = "www.example.com" NAKED_DOMAIN = "example.com" protected def ensure_domain if request.env['HTTP_HOST'] == NAKED_DOMAIN && RAILS_ENV =='production' #HTTP 301 is a permanent redirect redirect_to "http://#{APP_DOMAIN}", :status => 301 end end
This works fine for links that go to the home page. However I just realized that if I have a the following url: example.com/products The user gets redirected to the home page at www.example.com and NOT www.example.com/products How can I redirect to the URL the user is trying to access but the www.example.com root and not the example.com root. In other words if a user wants the following: example.com/products I send them to www.example.com/products Thanks for any assistance. I am hosted on Heroku. I am using Zerigo DNS. When I tried using the DNS to forward all traffic from the naked domain to the www.example.com domain the URL still shows the naked domain. So that did not work. |
| Rails 4 - Pundit - policies not working Posted: 01 Jul 2016 08:09 PM PDT I'm trying to figure out how to use Pundit in my Rails 4 app. I have a project model, with a projects controller that has a new action in it: def new # a bunch of stuff in the new action that I don't think is very relevant here end
I then have a project policy in my policies folder that has: def new? false # create? end def create? false end
I expect that I should not be able to type url/projects/new in my website because the policy shouldn't allow it. But, I can, and the form renders and I can save it. Does anyone see what I've done wrong in setting this up? |
| why do i get a NoMethodError in Devise::RegistrationsController#create in ActionMailer? Posted: 01 Jul 2016 06:28 PM PDT I've set up my config to use Mailtrap on Heroku and can confirm that I've got the bulk of it set up. Meaning I receive the emails, but only so long as I don't call methods on the user model. Personalizing the emails with @user.name and automating the user it sends to with @user.email results in a no method error. I thought maybe it had something to do with the fact that I'm sending emails from the user model instead of my customized devise users controller, so I added a create method to that. Which did nothing. The error says undefined method 'email' for nil:NilClass In my user model I have class User < ActiveRecord::Base after_create :new_user validates :email, presence: true, uniqueness: true, if: -> { self.email.present? } private def new_user UserMailer.new_user(@user).deliver_now end end
In my user mailer I have class UserMailer < ApplicationMailer def new_user(user) @user = user mail(to: @user.email, subject: 'You will be notified when your account is activated.') end end
And then in my users controller, which is extended from Devise::RegistrationsController, I have class UsersController < Devise::RegistrationsController def create @user = User.new(sign_up_params) end private def sign_up_params params.require(:user).permit(:firstname, :lastname, :email, :password, :password_confirmation, :approved) end end
Any idea? |
| How to create a offer strip on top of the navbar of the website which can be minimized? Posted: 02 Jul 2016 04:46 AM PDT I saw this offer on a website which was being displayed above the navbar.  It looked like this once clicked on the arrow on the top right corner.  And how can I make it responsive? 
Can anyone share how to implement such a solution? Are there any already existing solutions which I can reuse? |
