| Searching for files with a specific pattern Posted: 22 Jan 2017 07:50 AM PST I'm trying to look for specific files in a directory using a pattern Lets say i have the id of the user - 101 here are my files 101 101_2 101_5 10111 103 10125 101_6
I'm trying to form a regex pattern which only gives me files (101,101_2,101_5,101_6) I'm trying the below pattern ^101_?\d+$
but it doesnt seem to pick any of the files at all. if i remove the ^.only 101_6 matches for some reason. EDIT: I'm using rails/ruby to look for files in the particular directory. so something like Dir.glob(location).grep("^101_?\d+$") do something end

| Array of hashes is overriding data directly to array Posted: 22 Jan 2017 06:20 AM PST I want to make an array of hashes. But the problem is after first iteration when code goes to next line then it directly replaces the content of array. @item_name =[] item = {} @invoiceinfo.each do |invoice| item[:name] = Invoiceinfo.find(@invoiceinfo.id).item.name item[:desc] = Invoiceinfo.find(@invoiceinfo.id).desc item[:unit_price] = Invoiceinfo.find(@invoiceinfo.id).unit_price byebug @item_name.push (item) end
This is what i am getting after first iteration suppose i have this data @item_name = [{:name=>"usman", :desc=>"sample ", :unit_price=>100}]
As soon as next line is executed it directly changes @item_name(name variable) After executing item[:name] = Invoiceinfo.find(@invoiceinfo.id).item.name the content of the @item_name is changed @item_name = [{:name=>"next_name", :desc=>"sample ", :unit_price=>100}] Any help would be appreciated.

But then I get the following error: SQLite3::SQLException: no such column: users.message_id: SELECT "users".* FROM "users" WHERE "users"."message_id" IN ('1', '2', '3', '4', '5', '6', '7', '8', '9')
How it can be fixed? I want to return a collection of messages - not a user and a messages set inside the user. but without the N+1 problem |
| Rspec prevent method from being called Posted: 22 Jan 2017 07:00 AM PST I am testing a controller method for creating new orders (e-commerce-like app). If user is present in the system, he should be redirected to new_user_session_path, else to new_order_path. Simple as that. This is my orders_controller.rb def new if !User.where(phone: params[:phone]).blank? && !user_signed_in? redirect_to new_user_session_path() flash[:info] = "Already present" else @order = Order.new @menu = Menu.find(params[:menu_id]) @menu_price = @menu.calculate_price(@menu, params) end end
In my app, I need the calculate_price method to be called, because it calculates the overall price given the params. But in my test, I just want to ensure, that the redirect is correct. Right now I'm getting errors like (they are sourced inside the Menu.rb file, since calculate_price is called) : Front::OrdersController#new redirects user to new order page if user is not present in the system Failure/Error: menu_price_change = menu_amount.split(",")[1].gsub(" ","").gsub("]",'') NoMethodError: undefined method `split' for nil:NilClass
This is my spec file: require 'rails_helper' describe Front::OrdersController, type: :controller do describe '#new' do # Set up dummy menu let (:menu) { Menu.create() } it "redirects user to sign up page if user is present in the system" do user = User.create(name: "Bob", password: "bobspassword", phone: "+7 (903) 227-8874") get :new, params: { phone: user.phone } expect(response).to redirect_to(new_user_session_path(phone: user.phone)) end it "redirects user to new order page if user is not present in the system" do non_present_phone = "+7 (903) 227-8874" get :new, params: { phone: non_present_phone, menu_id: menu.id} expect(response).to redirect_to(new_order_path) end end end
Of course I could provide all the params, but there is a pretty big amount of them and besides, I just want to test the correct redirect. As far as I know, mocks and subs are useful in this case, when you want to explicitly test the methods. But in my case, I want to - somehow - omit them. How can I ensure that behaviour? |
| Unable to install will_paginate gem Posted: 22 Jan 2017 05:34 AM PST I tried installing will_paginate gem in rails but it somehow not working in mine. I am unable to start my rails server. Bundler::GemNotFound: Your bundle is locked to will_paginate (3.1.5), but that version could not be found in any of the sources listed in your Gemfile. If you haven't changed sources, that means the author of will_paginate (3.1.5) has removed it.

| Soundcloud embed player in rails Posted: 22 Jan 2017 04:18 AM PST I am a beginner and trying to work out how to use rails..I am making a CRUD system to play soundcloud tracks on my website. I'm creating a form so I can 'create' a song by inserting the soundcloud embed code in the fieldset to display the soundcloud widget on the view page. My question is how can I use the embed code in the form below?? <%= form_for @song do |f| %> <fieldset> <%= f.label :name %> <%= f.text_field :name %> </fieldset> <fieldset> <%= f.label :artist_id %> <%= f.select :artist_id, Artist.pluck(:name, :id), :include_blank => true %> </fieldset> <fieldset> <label></label> <%= f.submit %> </fieldset> <% end %>
this is my Songs controller class SongsController < ApplicationController def index @songs = Song.all end def new @song = Song.new end def create song = Song.create song_params redirect_to song end def edit @song = Song.find params[:id] end def update song = Song.find params[:id] song.update song_params redirect_to song end def show @song = Song.find params[:id] end def destroy song = Song.find params[:id] song.destroy redirect_to artists_path end private def song_params params.require(:song).permit(:name, :artist_id, :user_id) end end
Also I can't use the soundcloud API because I applied for it but I didn't receive a response. Would there be a way to display the widget on the website without the api? Can anybody let me know if this is the right approach and a step by step guide on how I can achieve this? Thank you so much.. |
| Rendering a form after Ajax request doesn't load tinyMCE 4 plugin (again) Posted: 22 Jan 2017 04:03 AM PST I have a form partial being loaded in my view 'powered' with tinyMCE. I'd like the form to do the following: - Create an instance of OpenEnder via Ajax
- After creation a form should still be there, loading the recently saved @open_ender allowing the instance to be updated via Ajax again
- TinyMCE should be always available for text formatting.
I'm able to achieve the first 2 points. However, although tinyMCE is loaded when the page is first rendered, I haven't been successful keeping tinyMCE active after the Create Ajax action. The issue is driven by the need of re-rendering the form partial after a Create Action in order to update the HTTP method so it updates the instance rather than keep creating instances. When I do this tinyMCE is not loaded in the new form. I've tried re-loading tinymce init after Create, wrapping tinymce.init in a function so I can call it after Create tinymce.remove() before calling init function as suggested in here without success. Any help would be appreciated. layouts/application.html.erb (in ) <script> var initTinymce = function() { tinymce.init({ selector: ".tinymce", plugins: [ "autosave save"], toolbar1: "save restoredraft | fullscreen | undo redo ", autosave_retention: "20m" }); } initTinymce(); <script>
answers/show.html.erb <%= render 'open_enders/form', open_ender: @open_ender, answer: @answer %>
open_enders/_form.html.erb <%= simple_form_for open_ender, remote: true, authenticity_token: true, html: { id:'open_ender_form' } do |f| %> <%= f.error_notification %> <div class="form-inputs"> <%= f.input :answer_id, :required => true, :as => :hidden, :autofocus => true, input_html: {value: @answer.id } %> <%= f.input :content, :label => false, :placeholder => "write your thoughts here...", :required => true, :autofocus => true, input_html: { class:'tinymce' } %> <%= button_tag(type: 'submit', id: "save-btn", style:'background:transparent' ) do %> <span id="inline_alert" class="hide">Remember to save your changes!</span> <% end %> </div> <% end %>
open_enders/create.js.erb ('#open_ender_form').replaceWith("<%= j render 'open_enders/form', open_ender: @open_ender, answer: @answer %>"); initTinymce();

| Rails on WINDOWS: install therubyracer & libv8 - working on a website designed on MAC Posted: 22 Jan 2017 03:37 AM PST I have a website developed with was RoR v 4.2.4 on MAC which needs some adaptions and I'm trying to get in running on my windows 10 (because I don't have a MAC).I was not successfull with the rails installer and rails 5.0. After a lot of pain installing RoR 4.2.4 with ruby 2.2.6 I managed to install nearly all missing gems using bundle check, bundle install and gem install xyz -v 0.0.... But now I'm really stuck with the last 2: therubyracer and libv8 What I tried: Install libv8 with gem install libv8 -v 3.16.14.11 -- --with-system-v8 and also the therubyracer-for-windows which is mentioned here. Modify the gemfile.lock to get rid of the dependencies like: group :production do gem 'therubyracer' end
and tried bundle install --without production. But then I get an error when starting the server. At the moment bundle check says that therubyracer v 0.12.2 is the last missing gem. libv8 is installed with --with-system-v8. gem list says libv8 (3.16.14.11) and therubyracer (0.11.0b) is installed but the systems does not seems to find therubyracer because: therubyracer -v does not work. Furthermore bundle install give me the follwing error: C:/Ruby22-x64/bin/ruby.exe -r ./siteconf20170122-10664-jwvn48.rb extconf.rb --with-v8-dir=/usr/local/opt/v8-315 checking for main() in -lpthread... yes checking for v8.h... no *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

This error is at least similar to all the ones I get before, when trying to install therubyracer after I installed libv8 with --with-system-v8.

If there is important information missing, let me know. By the way: I followed this guide as good as possible. Creating/Developping a new website with rails new blog and running the server for it works perfectly...the problem is only with the existing website I have to complete. Can someone help me? Is there any way to get the website running on my windows pc? Thanks! |

| Unable to make auto focus on fields for bootstrap modal Posted: 21 Jan 2017 11:32 PM PST Hi so following this rails tutorial using coffeescript , a part of this function is suppose to find the bootstrap div modal, then find the "textarea" within it to auto focus it immediately . ready = -> $(".media").on "click", -> document.location = $(this).data("target") return false $(".modal").on "shown.bs.modal", -> $(this).find("textarea").focus() $(document).ready(ready) $(document).on "page:load", ready
The .media function click is working so far. However, another function which uses the shown.bs.modal is not working... I tried to Console.log or alert it as well but it seems that $(".modal").on "shown.bs.modal", is not working and i'm not sure why. Here is my html <div class="modal fade" tabindex="-1" role="dialog" id='new-question-modal'> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title">Modal title</h4> </div> <div class="modal-body"> <!--body of modal--> <!--Form body <form action="/questions" method="POST">--> <%=form_for :question,url: '/questions', html: {class: 'form-group'} do %> <div class="form-group"> <label for="exampleInputEmail1">Email address</label> <input type="email" name="question[email]" class="form-control" value = "<%= current_user_email%>" id="exampleInputEmail1" placeholder="Email"> </div> <div class="form-group"> <label for="inputQuestion" class="control-label">Question:</label> <textarea class="form-control" name="question[body]" id="inputQuestion" placeholder="What would you like to know" required=""></textarea> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> <button type="submit" class="btn btn-primary">Submit</button> </div> <%end%> <!--body of modal</form>--> <!--Form body--> </div> </div><!-- /.modal-content --> </div><!-- /.modal-dialog --> </div><!-- /.modal -->
From what i can tell it's suppose to identify the modal groups , and modal fade is one of them? Below here is a sample of the webpage , where i click the green button and a form pops out which is the modal i took from bootstrap.

| HABTM Association with FactoryGirl Posted: 22 Jan 2017 05:08 AM PST Have looked through and tried most examples and still cannot create a working HABTM. No matter how the CaseTrack and CaseTrackValue factories are constructed, I'm not able to find the CaseTrackValue[] in CaseTrack. Shouldn't creating CaseTrack properly provide a CaseTrackValue param within CaseTrack.
BTW: the only working association for HABTM seems to be putting case_track_values { |a| [a.association(:case_track_value)] } in CaseTrack.
class CaseTrack has_and_belongs_to_many CaseTrackValue end class CaseTrackValue has_and_belongs_to_many CaseTrack end Rspec it 'may exercise the create action' do post '<route>', params: {case_track: attributes_for(:case_track)} end end class CaseTrackController < ApplicationController private: def case_track_params params.require(:case_track).permit(:name, :active, {case_track_values:[]}) end end

| Can I use an instance method for a computed value in a rails model? Posted: 22 Jan 2017 01:54 AM PST I have a model that has a time length (minutes and seconds columns) as part of its data. I would like to add a method to return the time formatted as mm:ss (like 09:08). I've made a method to do this and tested it using irb. But when I try to access the value from my view, it looks like the instance variables are not being initialized and I'm getting "00:00" for all of the values. In looking here and elsewhere, it looks like I could make a class method (by adding self.) and pass the value in for formatting but that seems redundant. The model instance should already have the data. Is using a class method the ruby way? Or am I doing something else obviously wrong? class Segment < ApplicationRecord belongs_to :course def time m = pad @min s = pad @sec m + ":" + s end def pad(x) x.to_s.rjust(2,"0") end end view: <%= segment.time %> # returns 00:00 <%= segment.min %>:<%= segment.sec %> # returns correct non-padded values

| How can i set an Order in a Rail's Jbuilder JSON Posted: 21 Jan 2017 08:00 PM PST I'm developing an simple invoicing app in Rails 5 For this question I have 2 models. Quote class Quote < ApplicationRecord belongs_to :client, optional: true has_many :quote_items, dependent: :destroy accepts_nested_attributes_for :quote_items end
And QuoteItem class QuoteItem < ApplicationRecord default_scope { order(:id, :item_order) } belongs_to :quote end
Because i have a scope in the QuoteItem model I can display the data in my erb based in the item_order field. But now i need to use the same data in JSON for build a dynamic table. And the Scope in my QuoteItem model is not working with Jbuilder. This is the JSON format: #myapp/app/views/quotes/show.json.jbuilder json.quote do json.partial! "quotes/quote", quote: @quote json.quote_items do json.array!(@quote.quote_items) do |item| json.id item.id json.clave item.product.clave json.name item.name json.quantity item.quantity json.item_order item.item_order json.days item.days json.unit_price item.unit_price json.seguro item.seguro json.descuento item.descuento json.total item.total end end end
My question is How can I set the sort order of json.quote_items with the "item_order" field instead of his "id". |

Verified by the fact i can see the authentication take place on the rails api and the user creds passed back. Due to the fact that it works on ionic serve i'm guessing this must be something to do with either the cordova permissions or the fact that the rails 5 api isn't configured to allow access via an app without an ip? I've therefore tried also using the cordova whitelist plugin. Whitelisting all ips, and completely opening up the permissions on the api using Rack-Cors gem. I've googled the sh*t out of this and am completely stumped. Code snippets below: In my ionic app app.js .config(function($authProvider) { $authProvider.configure({ apiUrl: 'http://localhost:3000', storage: 'localStorage' }); }) .config(function($stateProvider, $urlRouterProvider) { $stateProvider .state('auth', { url: "/auth", templateUrl: "views/auth.html", abstract: true, }) .state('auth.welcome', { url: '/welcome', templateUrl: "views/welcome.html", controller: 'WelcomeCtrl' }) .state('dashboard', { url: '/dashboard', templateUrl: "views/dashboard.html", controller: 'DashboardCtrl', }) ; // if none of the above states are matched, use this as the fallback $urlRouterProvider.otherwise('/auth/welcome'); })
welcome controller - redirect on auth. $auth.validateUser().then(function(resp) { console.log('validated User'); $window.location.href = '/#/dashboard'; // $state.go('dashboard'); });

All help or hints much appreciated in advance! |
