| JSONResources gem: namespaced routes Posted: 18 Jan 2017 07:43 AM PST I'm playing with the JSONResources gem and it's having trouble getting named routes to show up in the links attribute when I hit an index action that paginates results. In my config/routes file, I've got this: scope :module => :api, defaults: { format: 'json' } do constraints APIConstraints::APIVersion.new(1) do scope :module => :v1 do jsonapi_resources :guidelines end end end
The APIConstraints class mentioned above inspects the headers to see if the request specifies API version. If no version is specified, it'll set a default version (in this case, version 1). When I inspect the routes, things look normal. $ rake routes Prefix Verb URI Pattern Controller#Action guidelines GET /guidelines(.:format) api/v1/guidelines#index {:format=>"json"} ...
When I curl the endpoint to list various guidelines, it returns the payload I'd expect, but the links attribute completely ignores the named routes. I get something like this: "links": { "first": "http://localhost:3000/api/v1/guidelines?page%5Blimit%5D=30&page%5Boffset%5D=0", "last": "http://localhost:3000/api/v1/guidelines?page%5Blimit%5D=30&page%5Boffset%5D=1250", "next": "http://localhost:3000/api/v1/guidelines?page%5Blimit%5D=30&page%5Boffset%5D=30" }
When I read through the documentation, but I didn't see anything that addressed how to get the links attribute to respect the named routes. Am I just misusing this gem's API or is there some way to accomplish this task? |

| parsing json from google distance matrix Posted: 18 Jan 2017 07:02 AM PST In a rails application, the query to google's distance matrix returns proper data. The controller generates the result in an object matrix.origins << origin matrix.destinations << destination matrix.data @data = matrix.data
which is an array of hashes. the instance variable @data returns [[#<GoogleDistanceMatrix::Route origin: #<GoogleDistanceMatrix::Place lat: 61.1173, lng: 13.8875>, destination: #<GoogleDistanceMatrix::Place lat: 61.3405325, lng: 13.7243266>, status: "ok", distance_text: "56.9 km", distance_in_meters: 56948, duration_text: "1 hour 6 mins", duration_in_seconds: 3944>]] However the <%= data["distance_text"].to_s %> statement generates a no implicit conversion of String into Integer when I am not interested in the integer. Thus I suspect it is calling the index, when I expected the each command to handle it. How can this be done properly? |

| Rails Eager loading has_many associations for an existing object Posted: 18 Jan 2017 05:49 AM PST I am fairly new to rails & I am having this performance issue that I would appreciate any help with. I have a User model & each user has_many UserScores associated. I am preparing a dashboard showing different user stats including counts of user_scores based on certain conditions. Here is a snippet of the code: def dashboard @users = Array.new users = User.order('created_at ASC') users.each do |u| user = {} user[:id] = u.id user[:name] = u.nickname user[:email] = u.email user[:matches] = u.user_scores.count user[:jokers_used] = u.user_scores.where(:joker => true).length user[:jokers] = u.joker user[:bonus] = u.user_scores.where(:bonus => 1).length user[:joined] = u.created_at.strftime("%y/%m/%d") if user[:matches] > 0 user[:last_activity] = u.user_scores.order('updated_at DESC').first.updated_at.strftime("%y/%m/%d") else user[:last_activity] = u.updated_at.strftime("%y/%m/%d") end @users << user end @user_count = @users.count
end The issue I am seeing is repeated UserScore db queries for each user to get the different counts. Is there a way to avoid those multiple queries?? N.B. I'm not sure if my approach for preparing data for the view is the optimal way, so any advice or tips regarding that will be greatly appreciated as well. Thanks |
| Random ActionController::InvalidAuthenticityToken Posted: 18 Jan 2017 07:18 AM PST I get random ActionController::InvalidAuthenticityToken errors on my production server. There are no AJAX requests, all forms are created with Rails helpers (so they do include hidden field with authenticity_token). The problem appears randomly on random forms. In my ApplicationController I have before_action :expires_now. Could that be a problem? I added this because my users often click 'back' in their browsers and I didn't want them having cached results.

| List sub controllers in Rails Posted: 18 Jan 2017 03:38 AM PST In my Rails app I have an AdminController in app/controllers/admin: module Admin class AdminController < ApplicationController end end
And then inside the admin folder I have various other controllers which all inherit from the AdminController, e.g. module Admin class PermissionsController < AdminController end end
I'm trying to list all the controllers and actions under AdminController with: def list @controllers = AdminController.descendants end
But all I get is: Admin::PermissionsController I've also tried AdminController.subclasses but get the same. I don't want to do @controllers = Dir.new("#{Rails.root}/app/controllers/admin").entries because I also want to access the action_methods. Why isn't descendants or subclasses working? In my view I want to do: <% @controllers.each do |controller| %> <h2><%= controller %></h2> <ul> <% controller.action_methods.each do |action| %> <li><%= action %></li> <% end %> </ul> <% end %>
Which does list all the actions but only for the current controller and it also lists action methods from the parent controllers. I only want to list the ones for each controller. |

| List sessions for current user only in Rails Posted: 18 Jan 2017 06:42 AM PST I'm using the activerecord-session_store gem to store sessions in the database. I list sessions with this method in my SessionsController: def index @sessions = Session.all end
However this lists ALL sessions in the app and not just ones for the currently logged in user. The database table for sessions has the following columns: id, session_id, data, created_at, updated_at so there is no user_id column to filter on. I can access the user_id in the session data with Marshal.load(Base64.decode64(session.data))['user_id'] How can I use this data to filter the list? So far all I can think of is to do a conditional in the View that compares it against the current_user.id e.g. <% @sessions.each do |session| %> <% if Marshal.load(Base64.decode64(session.data))['user_id'] == current_user.id %> <!-- LIST SESSION --> <% end %> <% end %>

| how to set Mandrill with DKIM and SPF in order to receive the activation link via mail Posted: 18 Jan 2017 02:32 AM PST I am working on a new app (Ruby On Rails) and I have been stocked on Mandrill. The settings are fine because when I try to register a new user I can see in the terminal the actiovation link and I can go through my registration but I don't receive any mails because I have no idea how to set this:  I tried to follow all the guides but I didn't get them. Where should I CHANGE these settings? Thanks for your help |
| Respect negative conditions for advanced collection associations Posted: 18 Jan 2017 02:32 AM PST I was trying to use this functionality introduced in #645 with conditional 2nd degree has_many ... through relationships with little success. In my case: - a Course
has_many :user_assigned_content_skills, -> { where(source: 'user') }, class_name: "ContentSkill" - and a ContentSkill
belongs_to :skill and belongs_to :course Then Course.ransack({user_assigned_content_skills_skill_name_not_cont: 'ruby'}).result.to_sql returns the following: "SELECT courses.* FROM courses LEFT OUTER JOIN content_skills ON content_skills.course_id = courses.id AND content_skills.source = 'user' LEFT OUTER JOIN skills ON skills.id = content_skills.skill_id WHERE (skills.name NOT ILIKE '%ruby%')"
This means false positives again if a course has multiple content_skills. Any ideas how to retrieve all courses not being associated with a given skill name? Many thanks for any insights! |
| Sending message from autobahn Android Posted: 18 Jan 2017 02:20 AM PST I've got a Rails websocket/server set up and want to send messages from my phone to the server. The implementation of Autobahn is the following (template): private final WebSocketConnection mConnection = new WebSocketConnection(); private void start() { final String wsuri = "ws://localhost:9000"; try { mConnection.connect(wsuri, new WebSocketHandler() { @Override public void onOpen() { Log.d(TAG, "Status: Connected to " + wsuri); mConnection.sendTextMessage("Hello, world!"); } @Override public void onTextMessage(String payload) { Log.d(TAG, "Got echo: " + payload); } @Override public void onClose(int code, String reason) { Log.d(TAG, "Connection lost."); } }); } catch (WebSocketException e) { Log.d(TAG, e.toString()); } }
That is working fine for receiving, but how do I send something back? |
| Rails 4 - controller not being called Posted: 18 Jan 2017 04:39 AM PST I can hit the importers#import_vendor_ledger action but I can't seem to hit the importers#import_chart_of_accounts action via the redirect_based_on(arg) method inuploaders#upload_file. Please help! NOTE: I left out some code that I didn't think was necessary to see My code: routes.rb resources :uploaders do collection { post :upload_file } end resources :importers do collection { post :import_vendor_ledger, :import_chart_of_accounts } end
index.html.haml #chart_of_accounts = form_tag upload_file_uploaders_path, multipart: true do = hidden_field_tag :account, "chart_of_accounts" = file_field_tag :file = submit_tag 'Upload Chart of Accounts' #vendor_ledger = form_tag upload_file_uploaders_path, multipart: true do = hidden_field_tag :account, "vendor_ledger" = file_field_tag :file = submit_tag 'Upload'
uploaders_controller.rb class UploadersController < ApplicationController include Excel def upload_file uploaded_io = params[:file] if uploaded_io.path.downcase.end_with?(xlsx_extension) save_to_storage(uploaded_io) flash[:success] = 'File uploaded successfully!' redirect_based_on_(params) # this is where it should call the action else flash[:warning] = 'ERROR: The file you upload MUST be an ".xlsx" excel file!' redirect_to root_url end end private def redirect_based_on_(_params) case _params[:account] when "vender_ledger" redirect_to import_vendor_ledger_importers_path and return when "chart_of_accounts" redirect_to import_chart_of_accounts_importers_path and return end end end
importers_controller.rb class ImportersController < ApplicationController include Excel def index end def show end def import_vendor_ledger # I can hit this action puts "hits vendor ledger import" end def import_chart_of_accounts # but I can't hit this action puts "hits chart of accounts import" end
EDIT #1: even if I explicitly call redirect_to import_chart_of_accounts_importers_path in uploaders#upload_file it still doesn't hit the importers#import_chart_of_accounts action EDIT #2: after inspecting more, it seems that importers#import_chart_of_accounts action IS being hit, but none of the functions in the action is being called |
| can't dynamically add activeadmin gem to autoload_paths Posted: 18 Jan 2017 06:06 AM PST I am using heroku for my main app, but now i have separated it to main_app and admin_app (memory issues). So i have 2 apps running on the same git repo with no problems. main_app uses subdomain admin. to resolve admin_app now i want to save some memory without loading active admin. i use a group in gemfile group :admin_app do gem 'activeadmin', git: 'https://github.com/activeadmin/activeadmin' end
and in application.rb when admin_app loaded Bundler.require(*Rails.groups,:admin_app)
Now, i have the admin folder which is located on app/admin gets auto loaded so i have to ignore it or else i get an exception (no active_admin gem on main_app) i solved it by a simple if statement if Rails.application.secrets.admin_app ActiveAdmin.register ForumTopic .... end
i am looking for a better fix for this problem . i tried moving admin folder to lib or outside the app folder and then add it to config.autoload_paths << Rails.root.join('admin')
but i just don't see it get loaded when using ActiveSupport::Dependencies.autoload_paths
i whould like to hear your ideas, thank's |
