| Dynamic Data with Google Tag Manager and TurboLinks Posted: 03 Jan 2017 08:00 AM PST How can I set up GTM with TurboLinks? The problem: GTM and the SEO team asks me to add this to my Head: <% if user_signed_in? %> dataLayer = [{'userID': '<%= current_user.id %>'},{'userCategory': 'User'}]; <% end %> </script> <!-- Paste this code as high in the <head> of the page as possible: --> <!-- Google Tag Manager --> <script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start': new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0], j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src= 'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f); })(window,document,'script','dataLayer','GTM-N7MDCP');</script> <!-- End Google Tag Manager -->
This will be cached by TurboLinks. I could try to wrap this in page:change, but that won't update the values for user_signed_in etc. Can I safely move this into the body, where TurboLinks will refresh it? If not, how else can i get GTM to work with a dynmic datalayer and GTM? |
| Optional where in Rails Posted: 03 Jan 2017 07:53 AM PST How can I make a where optional in Rails? I tried: @pages = Page .where(status: params[:status].present? ? params[:status] : 1) .where(parent_id: nil) if params[:status].blank? .order(sort_column + ' ' + sort_direction)
But it looks to exit the block and instead returns: undefined method 'where' for true:TrueClass. |

| api resource rails routes Posted: 03 Jan 2017 07:20 AM PST So I have some API resources in my app, and some regular resources, and for regular resources I use : resources :books
And then I could pass except: %i(destroy new edit) or only so works great! However for my resource I ll never have new/edit actions, sometimes I will need to pass except and only options too. I was thinking to create something like: api_resources :books Which comes without new/edit actions by default, how would I do that? |
| Can't hit API endpoint in Rails using Mongodb Posted: 03 Jan 2017 07:40 AM PST I am attempting to build a Rails backend using Mongodb that is just an API application. I have an events model and api controller and when I go to localhost:3000/events/2, I am getting a 404 error, although I know the record is in my database: { "_id" : 2, "name" : "String Cheese", "location" : "Durham, NC", "price" : "40.00" }
My controller looks like this: class API::V1::EventsController < ApplicationController respond_to :json def show respond_with Event.find('_id') end private def event_params params.require(:event).permit(:name, :url, :location, :dates, :price, :info, :genre, :address, :city, :tags) end end
And my routes look like this: require 'api_constraints' Rails.application.routes.draw do namespace :api, defaults: { format: :json }, path: '/' do scope module: :v1, constraints: ApiConstraints.new(version: 1, default: true) do resources :users, only: [:show] resources :events, only: [:show] end end end
And then I have an api_constraints.rb in my lib folder that looks like this: class ApiConstraints def initialize(options) @version = options[:version] @default = options[:default] end def matches?(req) @default || req.headers['Accept'].include?("application/vnd.marketplace.v#{@version}") end end
This is to remove the need for having the api version number in the uri. I'm not sure if it is effecting my endpoint. So then when I start my server and go to localhost:3000/events/2 I get a 404 error: {"status":404,"error":"Not Found","exception":"#\u003cMongoid::Errors::DocumentNotFound: \nmessage:\n Document(s) not found for class Event with id(s) {\"_id\"=\u003e\"2\"}.\nsummary:\n When calling Event.find with an id or array of ids, each parameter must match a document in the database or this error will be raised. The search was for the id(s): {\"_id\"=\u003e\"2\"} The stack trace is actually even longer, so i can post the whole thing if anyone needs it. Any help would be greatly appreciated. |

| How do I get rid of brackets that are appearing around my Rails model error message? Posted: 03 Jan 2017 07:10 AM PST I'm using Rails 5. In my model, I set an error if one of my fields isn't valid ... errors.add(:my_field, 'The field is not in the correct format')

When the error is displayed, it appears as ["The field is not in the correct format"]

and My registrations_controller.rb is below. class Users::RegistrationsController < Devise::RegistrationsController def create super if resource.save resource.rewards.create(point: 60) end end end

| UnknownFormat with Devise and custom controllers Posted: 03 Jan 2017 06:29 AM PST I am using Rails 5 and Devise. Because I want custom layouts for login and recover password pages I had to run rails generate devise:controllers

Which opens a form where they can set their email and password but when I submit the form I get the error: ActionController::UnknownFormat in Devise::RegistrationsController#update

| Can't access data in ActiveHash Posted: 03 Jan 2017 05:56 AM PST I'm using the Gem active_hash https://github.com/zilkey/active_hash to create models for simple data that I don't want to create DB tables for. For example, I have this model setup for FieldTypes: class FieldType < ActiveHash::Base self.data = [ {:id => 1, :name => "text", :friendly_name => "Text"}, {:id => 2, :name => "textarea", :friendly_ => "Text Area"}, {:id => 3, :name => "image", :friendly_ => "Image"}, ] end
And I'm trying to list these field types for a select: def field_types_for_select #FieldType.all.order('name asc').collect { |t| [t.friendly_name, t.name] } FieldType.pluck(:friendly_name, :name) end
But I get an error that order, collect or pluck are not defined. How do I access this data? This works fine on other models, just not ActiveHash ones. According to the docs the model should work the same as ActiveRecord but I don't seem to be able to access it the same. FieldType.all works, but other methods do not. |

I got 3 controllers in my application and two of them are models. The 3rd controller is just a controller I made to handle the main views (the main interface) its not a model.

| Save Multiple Records Simultaneously with a single AJAX request? Posted: 03 Jan 2017 05:35 AM PST I'm using jQuery Sortable to drag cards between lists, like Trello. When the user is finished interacting with a card, I need to save all cards in that list. I'm currently doing it with an each loop, looping over all items of that type and saving each one with an AJAX request. ui.item.parent('.js-CardsContainer').children('.js-CardContainer').each(function() { var list_id = $(this).closest('.js-List').data('id'); var order = $(this).index(); var id = $(this).find('.js-Card').data('id'); console.log(order); $.ajax({ url: "/cards/" + id, type: "PATCH", data: { card: { list_id: list_id, order: order } }, success: function(resp) { // } }); });
It seems to work for lists with just a few cards. But when 5+ cards are being saved, some of them fail. I guess that's because separate AJAX requests are being used for each card? So, I think I need to combine all AJAX requests into a single request? I have no idea how to do that though. Can anyone help? This is going to my controller update action which looks like this def update @card = Card.find(params[:id]) if @card.update_attributes(shared_params) respond_to do |format| format.js {} format.json { render json: @card, status: :created, location: @card } end else render :edit end end

| Rails file upload: upload a folder Posted: 03 Jan 2017 06:31 AM PST I work on Rails project and client asked if I can add 'upload a folder' feature to simple file upload system that we have now. Currently it attaches files to model and then displays them on a page for download. Pretty basic. But I can't figure out how can I handle folder uploads, with every folder having it's own content. Is there any pre-made gems that can help accomplish that? We use Paperclip at the moment, but I don't mind migrating to Carrerwave or some other gem that would UPDATE I see that I was unclear about my needs. I need an upload system that could handle folders. Something like this.  In Dropbox I am able to upload both files and folders. How can I make my uploaders accept folders and then display them alongside regular attached files? |
| Prevent Maruku from posting so many log warnings Posted: 03 Jan 2017 05:08 AM PST I use Maruku in Rails simply to convert a Markdown file to HTML so I can use it with Nokogiri. (Maybe there's a better solution for that?) That works fine, but I get lots and lots of "Maruku tells you" messages in the log: ___________________________________________________________________________ | Maruku tells you: +--------------------------------------------------------------------------- | Could not find ref_id = "FIX" for md_link("FIX", nil) | Available refs are [] +---------------------------------------------------------------------------
That's really confusing and not needed here. Is there a way to silence Maruku so it only warns in the log if there's a real error? |

| filter nested json column on multiple values rails Posted: 03 Jan 2017 05:10 AM PST The JSON which is stored in the database column looks similar to "data": { "player": { "firstName": "John", "lastName": "Doe", "team": "London Blues" } }
and in my view I would like to have a search field, which accepts first name last name or a team name and filters the list accordingly. At the moment I have the following solution which I am not really satisfied and if there is any better ways to do it please share :) PlayerReqeust.where("initial -> 'data' -> 'player' ->> 'firstName' LIKE ? or initial -> 'data' -> 'player' ->> 'lastName LIKE ? or initial -> 'data' -> 'player' ->> 'team LIKE ?", "%John%", "%John%", "%John%")

| How to perform server-side filtering on a boolean column using Datatables.Buttons? Posted: 03 Jan 2017 04:12 AM PST I am adding Datatables to a Rails app, broadly following this Railscast (though adjusted to reflect syntax changes in recent versions of Datatables). The table has a boolean "approved" column. Using the Datatables Buttons extension, I want to add buttons to the table to filter records where approved = true or false. However I've been unable to find documentation that explains what buttons expects to receive to perform manipulations on the data. What I have so far (where data[6] is the 'approved' column): $elm = $('#toggle_table') $elm.DataTable 'processing': true 'serverSide': true 'ajax': $elm.data('url') buttons: [ { text: 'Approved' action: (e, dt, node, config) -> $.fn.dataTable.ext.search.push (settings, data, dataIndex) -> data[6] == true table.draw() $.fn.dataTable.ext.search.pop() } ]
However, while the logs appear to indicate that a request is sent to the server (NB server side processing), the table data is not changed. Also, I assume the params sent to the server should include the search term, which they don't: Parameters: {"draw"=>"3", "columns"=>{....."6"=>{...."search"=>{"value"=>"", "regex"=>"false"}}
What function does the Buttons extension expect to see here? Is Datatables clever enough to realize that the search function defined in the button action should be handled server side? Or do I need to explicitly define an ajax function here? |
| Deploying rails application bitnami rubystack GoDaddy Posted: 03 Jan 2017 04:19 AM PST I am new to using stacks such as those from Bitnami. I recently created a Bitnami RubyStack on GoDaddy, cloned my repository and did all the house cleaning. When i SSH into the server and run rails s -b MY_PUBLIC_ip -p PORT in the application directory and i open the browser, it works perfectly fine but when i close the SSH session and point to the same address there is nothing. The public IP still shows the welcome page. I think i misunderstood the whole concept. Can someone please help teach me how it is done. Thanks in advance. Update I heard something about creating virtual hosts but cant understand how the rails s command will run. Is it possible to start the server and it continues running even when the SSH session is closed. |
| Get data from Helper or use Model in Rails Posted: 03 Jan 2017 04:09 AM PST In my Rails app when creating a new Article I need a list of Users and Categories for some drop-downs so that I can choose both a category and an author for the Article. Currently I do this in the controller: def new @article = Article.new @categories = Category.order('title asc').collect { |t| [t.title, t.id] } @users = User.order('email asc').collect { |t| [t.email, t.id] } end
And then in the view: <%= f.select :category_id, options_for_select(@categories), :prompt => '-- Please Select --', :required => true %>
But according to RubyDocs this is bad practice, and it's not very DRY as I then have to do this for the edit method too. To prevent this, I have two possible alternatives I can think of: 1.) Use a helper like this: def users_for_select User.order('email asc').collect { |t| [t.email, t.id] } end def categories_for_select Category.order('title asc').collect { |t| [t.title, t.id] } end
And then in the view: <%= f.select :category_id, options_for_select(categories_for_select), :prompt => '-- Please Select --', :required => true %>
2.) Move it to a Model: def self.categories_for_select Category.order('title asc').collect { |t| [t.title, t.id] } end def self.users_for_select User.order('email asc').collect { |t| [t.email, t.id] } end
And then in the controller do this: def new @article = Article.new @categories = Category.categories_for_select @users = User.users_for_select end
Option 1 feels cleaner as it removes the code from the controller, but I was under the impression that option 2 would be better as it uses a Model for data (as intended) and the controller is still sending the data (again as intended) but more DRY. I feel their is a sometimes some overlap between Helpers and Models for getting data. |

Glitch or rendering issues (click links to view the images) normal after I click back button from the browser Can someone help me out why? Plus, my search forms are in the navigation bar in header partial file. |
Thanks for the useful steps. I usually pay good attention to how actively plugin is maintained & how often plugin supports questions are answered in the forum.
