ActiveRecord's query misbehavior for outer joins? Posted: 23 Oct 2016 07:33 AM PDT Lets have two ActiveRecord models Product and Promotion Building query with outer join and alias for joined table column produces following invalid SQL: Product.distinct.includes(:promotion).select('promotions.advertised as featured'). references(:promotion).order('featured').limit(10).to_sql SELECT DISTINCT "products"."id", featured AS alias_0 FROM "products" ^^^^^^^^^^^^^^^^^^^ LEFT OUTER JOIN "promotions" ON "promotions"."product_id" = "products"."id" ORDER BY featured LIMIT 10 Execution results in database error: ActiveRecord::StatementInvalid: PG::UndefinedColumn: ERROR: column "featured" does not exist. As expected, because featured is alias to promotions.advertised column, not defined in table products. As you can see, ActiveRecord injects invalid "featured AS alias_0" expression into select. In addition, all columns of products table, except id, are omitted. Above misbehavior is related to simultaneous use of order AND limit methods. When any of them is omitted, produced SQL becomes correct. For example just single removal of limit produces right query: Product.distinct.includes(:promotion).select(promotions.advertised as featured'). references(:promotion).order('featured').to_sql SELECT DISTINCT promotions.advertised as featured, "products"."id" AS t0_r0, "products"."name" AS t0_r1, … FROM "products" LEFT OUTER JOIN "promotions" ON "promotions"."product_id" = "products"."id" ORDER BY featured Can anybody explain this behaviour ? Candidate for a bugreport or am I missing something ? tested with ActiveRecord ver. 4.2.7.1

JBuilder/Rails 5: return simple string instead of json object Posted: 23 Oct 2016 06:33 AM PDT using jbuilder and rails 5, is it possible to transform a model object into a simple string, for example with this object: tag = { tag: 'sometag', created_by: 1 } using _tag.json.jbuilder to serialize the model to: 'sometag' instead of: { "tag": "sometag", "created_by": 1 } the idea is that the index action of my controller returns an array of strings instead of an array of objects ['a','b','c'] not [{name:'a'},{name:'b'},{name:'c'}] The scaffolded contents of _tag.json.jbuilder is json.extract! tag, :name, :created_by I tried tag.name but the result is empty. How to do this with jbuilder?

Why it's useful to create RVM gemset for rails project Posted: 23 Oct 2016 06:29 AM PDT It's recommended to create a separate RVM gemset for each rails project. But I don't understand, why it's useful. Are there only aesthetics reasons? Because it is possible to install multiple gem versions globally and then write a version in Gemfile in case I need a specific version of a gem.

redirect rails id show method to rails permalink Posted: 23 Oct 2016 05:08 AM PDT I have the has_permalink gem set up and working fine. However, google is crawling my website with looking for events with ids, not the permalink. This is what i currently have: @event = Event.find_by_permalink(params[:id]) However when someone types in an ID e.g. /events/000001 then @event is blank. The solution I came up with is this: @event = Event.find_by_permalink(params[:id]) if @event.blank? @event = Event.find_by_id(params[:id]) end But I would rather have the website still show the friendly URL link in the URL rather than the ID of the event. Any ideas how I would approach this? Thanks Sam

Table showing the result of queries using rails Posted: 23 Oct 2016 07:24 AM PDT Here is my problem. I have a model called Visit (which belongs to Visitor model): create_table "visits", force: true do |t| t.datetime "created_at", null: false t.datetime "updated_at", null: false t.date "start" t.date "end" t.integer "idVisit" t.integer "employee_id" t.integer "visitor_id" t.string "status", default: "Confirmed" end I have a table like this (name, last name and serial number are visitor's fields): Name, Last name, Serial number, From, To Now I have four buttons: Current visits, Confirmed and about to start visits, Terminated visits, Visits to be approved I need that, clicking on these buttons, the table shows the result of queries. For example, clicking on Terminated visits the table will show all the visits having end < Date.today, clicking on Current Visits the table will show all the visits having start <= Date.today && end >= Date.today and so on and so forth. In addition, Current visits button should be considered selected as default. I don't have any idea about this kind of implementations being a newbie at Ruby on Rails and I really hope you can help me. Thank you in advance! EDIT: <div class="jumbotron3 text-center"> <div class="row"> <h1>Guests Visits</h1> <hr> <%=render :partial =>"layouts/sidebar"%> <div class="panel3"> <div class="panel-body"> <% if logged_in? %> <%=render :partial =>"shared/error_messages"%> <% if @employee.visits.any?%> <br><br> <input type="button" id='current' value='Current Visits'> <input type="button" id='confirmed' value='Confirmed Visits'> <input type="button" id='terminated' value='Terminated visits'> <input type="button" id='pending' value='Pending Visits'> <br><br> <table class="table2 display" id="visit">   <thead> <tr>     <th>Name</th>     <th>Last name</th>     <th>Serial number</th> <th>From</th> <th>To</th>   </tr> </thead> <%= render @visits %> </table> <br><br> <% end %> <% end %> </div> </div> My main problem is the following: I need to fill the table with visit.visitor.name, visit.visitor.lastname, visit.visitor.serialnumber, visit.start, visit.end (by default I need to show the results of button current). When I click on one button, the table should show just the entries which respect the condition associated the clicked button. Ex: if I click on terminated, the table should show the entries having end < Date.today.

Rails 5 missing template that was added to lookup Posted: 23 Oct 2016 06:17 AM PDT I have added into application.rb string config.paths['app/views'] << 'app/views/cabinet' and created a view 'app/views/cabinet/index.html.slim'. But when I go to route localhost:3000/manager/pages (It uses layout manager if it make sence), Rails gives the error Manager::PagesController#index is missing a template for this request format and variant. What I'm doing wrong?

Added Column Not accessible in next migration file Posted: 23 Oct 2016 05:11 AM PDT I have added a column to my table via a migration, but I am not able to access the added column in the subsequent migration file. When I execute rake db:migrate the migration aborts, but when I execute it again the migration succeeds, not sure what I am doing wrong. Any help would be appreciated. Thanks. below is the code where i am adding column ** class AddIsDispatchToUsers < ActiveRecord::Migration def change add_column :users, :is_dispatch, :boolean, :default=>false end end ** Now, when i try to access the column in next migration file it fails.

Dynamically mount Carrierwave uploader on serialized field Posted: 23 Oct 2016 02:24 AM PDT I'm creating this app where users are able to dynamically add custom fields (TemplateField) to a template (Template) and use that template on a page (Page). The custom fields can have type text or image, and have custom naming. A user can for instance create at field named Profile picture of type image to their template. I can't however figure out how to dynamically mount a CarrierWave uploader to fields of type image, when everything is saved to an hstore attribute (properties) on the page model. Any help is much appreciated! class Template < ActiveRecord::Base has_many :template_fields has_many :pages end class Page < ActiveRecord::Base belongs_to :template store_accessor :properties end class TemplateField < ActiveRecord::Base belongs_to :template end

How to properly load lib modules and classes in Rails 5 app Posted: 23 Oct 2016 01:38 AM PDT How do I include a 'lib/' class or module in my models, Grape API and tests? For example, I have a class: ROOT/lib/links/link.rb module Links class Links::Link ... end end And I want to include that class in my User model (app/models/user.rb), User Grape API (app/api/v1/users.rb), and testing suites (test/models/user_test.rb and test/api/v1/users/users_links_test.rb) I've tried adding this to my config/application.rb: config.autoload_paths += Dir["#{Rails.root}/lib/**"] but it doesn't work. What am I missing? How do I include lib files and how should I be calling those classes?

Model name and path after routing in Rails Posted: 23 Oct 2016 01:26 AM PDT Here's my routing resources :users do resources :tasks end I have an error in the page new (form rendering) That was before routing add and everything works great = simple_form_for(@task) do |f| Then I change it to = simple_form_for(@user_task) do |f| And got at error: undefined method `model_name' How should I fix it?

Ruby on Rails, taking data from Graphql and posting on it to Facebook-messenger Posted: 23 Oct 2016 12:22 AM PDT $message_text = message.text module STAPI HTTP = GraphQL::Client::HTTP.new("API_ADDRESS") Schema = GraphQL::Client.load_schema(HTTP) Client = GraphQL::Client.new(schema: Schema,execute: HTTP) end module Sticker Query = STAPI::Client.parse <<-'GRAPHQL' { stickers(query: "#{$message_text}", first: 21, after: "") { edges { node { fileUrl(fullWatermarked: true) } } } } GRAPHQL end result = STAPI::Client.query(Sticker::Query) First of all this is an messenger bot and with this messenger bot i am taking users input and i am searching the input in our database then i post something related with the input. So, in the code i can't search beacuse, in my opinion query: "#{$message_text}" is broken. I take users input with message.text . This input comes like this 'Hello' (with '). But i need to give query: "#{$message_text}" part like this "Hello"(with "). how can i give messenger.text to query part like this "Hello"

Different versions of the index page for ActiveAdmin Posted: 23 Oct 2016 12:20 AM PDT I'd like to have two different index pages for my model, i.e. /admin/posts/ will be the default index page and /admin/posts/index/special will be another version. Perhaps I'm missing something obvious, but I haven't found an explanation in the official docs.

How to define let! with mutliple objects in Rspec test? Posted: 23 Oct 2016 02:49 AM PDT I'm practicing my Rails tests and right now I don't know how to solve this issue: How to define multiple objects using let! method. It returns normal array, not ActiveRecord relation. I guess that they should be both ActiveRelation relation type to be able to compare. require 'rails_helper' RSpec.describe PostsController do let!(:posts) do [Post.create(title: "Title 1", body: "Body 1"), Post.create(title: "Title 2", body: "Body 2")] end describe "posts" do it "assigns @posts" do get :index expect(assigns(:posts)).to eq([posts]) end end end After running tests: PostsController posts assigns @posts (FAILED - 1) Failures: 1) PostsController posts assigns @posts Failure/Error: expect(assigns(:posts)).to eq([posts]) expected: [[#<Post id: 1, title: "Title 1", body: "Body 1", created_at: "2016-10-23 05:40:39", updated_at: "201...: "Title 2", body: "Body 2", created_at: "2016-10-23 05:40:39", updated_at: "2016-10-23 05:40:39">]] got: #<ActiveRecord::Relation [#<Post id: 1, title: "Title 1", body: "Body 1", created_at: "2016-10-23 05:...: "Title 2", body: "Body 2", created_at: "2016-10-23 05:40:39", updated_at: "2016-10-23 05:40:39">]> (compared using ==) Diff: @@ -1,3 +1,13 @@ -[[#<Post id: 1, title: "Title 1", body: "Body 1", created_at: "2016-10-23 05:40:39", updated_at: "2016-10-23 05:40:39">, - #<Post id: 2, title: "Title 2", body: "Body 2", created_at: "2016-10-23 05:40:39", updated_at: "2016-10-23 05:40:39">]] +[#<Post:0x000000063ef570 + id: 1, + title: "Title 1", + body: "Body 1", + created_at: Sun, 23 Oct 2016 05:40:39 UTC +00:00, + updated_at: Sun, 23 Oct 2016 05:40:39 UTC +00:00>, + #<Post:0x000000063ef228 + id: 2, + title: "Title 2", + body: "Body 2", + created_at: Sun, 23 Oct 2016 05:40:39 UTC +00:00, + updated_at: Sun, 23 Oct 2016 05:40:39 UTC +00:00>] # ./spec/controllers/posts_controller_spec.rb:13:in `block (3 levels) in <top (required)>' Finished in 0.43037 seconds (files took 2.4 seconds to load) 1 example, 1 failure Failed examples: rspec ./spec/controllers/posts_controller_spec.rb:10 # PostsController posts assigns @posts

Displaying and Creating multiple entities rails Posted: 22 Oct 2016 10:03 PM PDT Hey guys im learning rails and as an assignment we have to do a site where people can bet on sport matches. Each match has two teams and three dividends (local win, visitor win or draw) that determine the users profit for each bet. These bets alone have no value because they go on to a ticket associated with the user and the amount and where the total profit is calculated. The ticket consists of up to three bets. Right now i have all the logic and views of the Matches but im trying to do the ticket one and im having some trouble. I already display a list of matches to the user like this: Match list From there i would like it if the user could click on the dividend number to select the match and the result desired and that would make that selection one of the three possible bets. For instance, if the user clicks on the draw dividend that would load a bet with that dividend for those two teams and a draw result. Once the user clicks on a dividend i want to dynamically load a table showing the current bet selected and a "submit" button that from those bets generates the ticket and persists them all to the database, how can i do it in a simple way? Thank You!

How can I prepare my rails app for production? Posted: 22 Oct 2016 08:02 PM PDT I've built a marketplace application using Rails, Devise, Heroku, and Stripe Connect. I want to launch the application in about 30 days. I have never actually launched an app that will be available to customers and has money involved. I'm kind of hazy in regards to what I need to do from here out to make sure the application will work as intended for the customers. I've read Basecamps Rework book which motivated me to launch sooner than trying to perfect it and have made the app as agile as possible as a result. I can't say I'm much of a programmer as I learned rails and programming in my spare time. If anyone has any experience in managing a rails app for live production please give me tips on things you wish you knew before. Thank you!

MySQL/Rails - Mysql2::Error (Access denied for user 'rails_user'@'localhost' to database 'simple_cms_development'): Posted: 22 Oct 2016 07:56 PM PDT I'm new to both MySQL and Rails.

Form submission within render partial is showing errors for all forms on all objects Posted: 22 Oct 2016 07:20 PM PDT To clarify my title, my portfolio/show file looks like <p> <strong>Name:</strong> <%= @portfolio.name %> </p> <%= content_tag :canvas, "", id: "positions_chart", width: "300", height: "300", data: {positions: @positions } %> <h1>Positions</h1> <div class = 'table'> <table> <thead> <tr> <th>Name</th> <th>Quantity</th> <th>Stock</th> <th colspan="3"></th> </tr> </thead> <tbody id = "positions"> <%= render @positions %> </tbody> </table> </div> <h3>New Position</h3> <%= render 'positions/form' %> <%= link_to 'Edit', edit_portfolio_path(@portfolio) %> | <%= link_to 'Back', portfolios_path %> The file that is rendering in line <%= render @positions %> is my _position.html.erb file. <tr> <td class="col-md-1"><%= position.name %></td> <td class="col-md-1"><%= position.quantity %></td> <td class="col-md-1"><%= position.ticker %></td> <td> <%= form_for [@portfolio, position, @movement] do |f| %> <div id = "movement-errors"> <% if @movement.errors.any? %> <%= render 'shared/error_messages', object: @movement %> <% end %> </div> <div class="field"> <%= f.label :quantity, 'Buy' %> <%= f.number_field :quantity, class: 'form-control' %> </div> <div class="actions"> <%= f.submit class: 'btn btn-primary' %> </div> <% end %> </td> <td> <%= form_for [@portfolio, position, @movement], url: sell_portfolio_position_movements_path(@portfolio, position, @movement), method: :post do |f| %> <div id = "movement-errors"> <% if @movement.errors.any? %> <%= render 'shared/error_messages', object: @movement %> <% end %> </div> <div class="field"> <%= f.label :quantity, 'Sell' %> <%= f.number_field :quantity, class: 'form-control' %> </div> <div class="actions"> <%= f.submit class: 'btn btn-success' %> </div> <% end %> </td> </tr> When I submit a number to buy or sell shares, the post request goes through and a movement is created. The issue I'm having is that I want to show an error message when a person submits nothing ensuring that a movement always has an integer value. My first error when dealing with this problem was when I submitted a nil value, I would get an error saying @partials within the render line was not defined. So I defined the variable in movements_controller. When I submit a nil value now, 2 things happen: 1) the post goes through and a movement is made with a quantity of nil, and 2) All of the buy/sell forms on all the position objects show me the error saying quantity should be present. My movement class is defined class Movement < ApplicationRecord belongs_to :position validates :quantity, presence: true, numericality: true My movement create method is defined as def create @movement = @position.movements.build(movement_params) @movement.update_price_and_date @movement.trade ='buy' respond_to do |format| if @movement.save @position.update_attribute(:quantity, (@movement.quantity + @position.quantity)) format.html { redirect_to @portfolio, notice: "#{params[:movement][:quantity]} share(s) successfully bought." } format.js else format.html { render template: 'portfolios/show' } format.json { render json: @movement.errors, status: :unprocessable_entity } format.js end end end and the sell action is defined as def sell @movement = @position.movements.build(movement_params) @movement.trade ='sell' respond_to do |format| if @position.sell(params[:movement][:quantity].to_i) @position.update_attribute(:quantity, (@position.quantity - @movement.quantity)) format.html { redirect_to @portfolio, notice: "You sold #{params[:movement][:quantity]} share(s)." } format.json { render :show, status: :created, location: @position } else format.html { render 'portfolios/show' } format.json { render json: @position.errors, status: :unprocessable_entity } format.js end end end

Rails 5 display number of results when grouped Posted: 22 Oct 2016 08:18 PM PDT I'm building an app using will paginate and ransack. My controller: def index @q = Stockdiary.all.ransack(params[:q]) @stockdiaries = @q.result.joins(:product).group(:PRODUCT).select("SUM(UNITS) AS UNITS, SUM(PRICE) AS PRICE").paginate(:page => params[:page], :per_page => 30) end Then in my view I have this to show the number of entries found: <div> <%= pluralize(@stockdiaries.size, 'stockdiary') %> found</div> But as I am applying group, it shows {"1"=>6, "103"=>2, "104"=>1, "106"=>2, "115"=>2, "116"=>1, "118"=>1, "122"=>1, "124"=>2, "13"=>6, "130"=>1, "133"=>3, "137"=>2, "138"=>2, "14"=>2, "140"=>1, "142"=>1, "144"=>1, "145"=>1, "146"=>2, "148"=>3, "149"=>1, "151"=>3, "152"=>3, "154"=>4, "16"=>4, "160"=>1, "161"=>1, "163"=>2, "166"=>1, "170"=>2, "174"=>1, "18"=>2, "19"=>1, "2"=>1, "25"=>3, "27"=>2, "29"=>1, "31"=>1, "33"=>1, "34"=>1, "43"=>2, "49"=>2, "56"=>1, "70"=>6, "73"=>4, "83"=>1, "9"=>2, "9e249a40-82d3-499f-a2b8-9f8613ecfe81"=>2, "bcea85d5-2596-4e41-8245-e520bc2b07a8"=>2} stockdiaries found which shows thew number of entries for each product (as it's grouped by product). Obviously I need to show just the total entries, not for each product. How to fix this?

Skipping Active Record breaks Rails Generator Posted: 23 Oct 2016 02:33 AM PDT I created a new Rails project with the -O --api flags turned on, and rails g model is now broken for me: it does nothing and simply says "running via Spring preloader" (its not a Spring bug as I've tried removing Spring) and returns. After that, I created a new project (exactly the same, just without -O), and rails g model worked fine. Is it that skipping AR breaks generators? If so, how shall I avoid? I'm using Ruby 2.3.1 and Rails 5.0.0.1 on Ubuntu Linux 16.04 LTS.

ElasticSearch: Altering indexed version of text Posted: 22 Oct 2016 03:00 PM PDT Before the text in a field is indexed, I want to run code on it to transform it, basically what's going on here https://www.elastic.co/guide/en/elasticsearch/reference/master/gsub-processor.html (but that feature isn't out yet).

In Ruby, What exactly is the difference between RVM, Bundler and Rake? Posted: 22 Oct 2016 03:20 PM PDT I know RVM stands for Ruby Version Manager, and that it helps you manage the versions of ruby across projects.

Big discrepancy in ruby Time arithmetic used with active support Time extensions Posted: 22 Oct 2016 02:42 PM PDT This code should not have, to my understanding, produce different results between third and second examples. 0> Time.utc(1999, 12, 29) - Time.utc(1999, 12, 29) => 0.0 0> Time.utc(1999, 12, 29) + 1.month - Time.utc(1999, 12, 29) => 2678400.0 0> 1.month.to_i => 2592000 Oddly enough when I convert everything to Fixnum it's back to working as expected. 0> Time.utc(1999, 12, 29).to_i + 1.month.to_i - Time.utc(1999, 12, 29).to_i => 2592000 What is going on?
