| Why Rails create my text_fields with the same "name" value? Posted: 29 Oct 2016 07:33 AM PDT I have the next code: text.gsub(/%{(\w*)}/, text_field_tag(/(?<=%{)[^%]*(?=})/.match(text), nil)).html_safe
So if I have the next text input: %{abc}, it will replace by %{abc} with text_field and will call its name as abc. But if I have %{abc} -- %{cba} it will add 2 text_fields but with the same name values, abc and abc. But I need to make it as abc and for the second text_field cba. What's wrong and how can I improve my code? |

| How to decrease query execution time on a db with 20 million records | Rails, Postgres Posted: 29 Oct 2016 08:03 AM PDT I have a Rails app with Postgres db. It has 20 million records. Most of the queries use ILIKE. I have created a triagram index on one of the columns. Before adding the triagram index, the query execution time was ~200s to ~300s (seconds not ms) After creating the triagram index, the query execution time came down to ~30s. How can I reduce the execution time to milliseconds? Also are there any good practices/suggestions when dealing with a database this huge?

| NameError in ProjectsController#index Posted: 29 Oct 2016 06:47 AM PDT In my rails app I am getting the following error: NameError in ProjectsController#index app/controllers/projects_controller.rb:6:in `index'
My routes look like this: RailsStarter::Application.routes.draw do resources :projects root :to => 'pages#home' match '/' => 'pages#home' match '/overview' => 'pages#overview' match '/recruitmentInfo' => 'pages#recruitmentInfo'
And the problem controller: class ProjectsController < ApplicationController # GET /projects # GET /projects.json def index @projects = ::Project.all respond_to do |format| format.html # index.html.erb format.json { render json: @projects } end end
My investigations so far showed that Project is not yet initialized, but this shouldn't matter as it is a constructor, in its own class. I even tryed precompiling that by adding this line config.autoload_paths += %W( #{config.root}/app/controllers) to application.rb. Nothing seems yet to work. Any ideas will be greatly appreciated. Thanks! |
| Unable to run gem pristine on rails app Posted: 29 Oct 2016 06:16 AM PDT So I'm trying to run my first rails app on my new Mac and am having some difficulties. When trying to generate a basic model, I get this error: Ignoring bcrypt-3.1.11 because its extensions are not built. Try: gem pristine bcrypt --version 3.1.11
bcrypt is commented out in the gemfile so I don't know why I'm getting this error, and when I run gem pristine bcrypt --version 3.1.11, it seems to work, but doesn't change the bcrypt error. I can't seem to figure out what I'm doing wrong. I never had this issue on my pc. I appreciate any help. |
| Jquery validation plugin doesn't work with fields that have bracket name Posted: 29 Oct 2016 06:12 AM PDT This question's got asked a lot on Stackoverflow but I can't seem to resolve the problem using the solution of turning $bookingForm.validate({ errorElement: "div", rules: { booking[name]: { required: true, minlength: 2 }, booking[email]: { required: true, email: true } ...
into $bookingForm.validate({ errorElement: "div", rules: { "booking[name]": { required: true, minlength: 2 }, "booking[email]": { required: true, email: true } },
Note the bracketed names are put in quotes. Jquery and Jquery validation plugin both load fine. No errors shown in console. I'm using rails5.0.0.1. Previously I used middleman and the validation plugin worked pretty well (with un-bracketed names). Has anyone had this issue with jquery validation plugin in rails? |

| Expected exactly 2 elements matching "a [href="/"]", found 0 Posted: 29 Oct 2016 05:57 AM PDT I'm trying to check how many links are routed to root_path. My question is why the route in my _header.html.erb file are not counted by assert_select? (I'm a beginner to code and rails and I'm following Michael Hartl's tutorial) root_path is used in the page twice: <%= link_to "sample app", root_path, id: "logo" %> <li><%= link_to "Home", root_path %></li>

This is the partial code for my HTML file (_header.html.erb): <header class="navbar navbar-fixed-top navbar-inverse"> <div class="container"> <%= link_to "sample app", root_path, id: "logo" %> <nav> <ul class="nav navbar-nav navbar-right"> <li><%= link_to "Home", root_path %></li> <li><%= link_to "Help", help_path %></li> <li><%= link_to "Log in", '#' %></li> </ul> </nav> </div> </header>
