| Rails how to update instance variable value at every execution Posted: 12 Mar 2016 07:12 AM PST I need to solve two problems with this piece of code inside a model. As far as I figured out the values in instance variables will be saved the first time it is executed, but since it is date and time it should be executed every time the method is called. How to go around that? Second, How can I access the instance variables inside the downtime method? def entry_time @day = DateTime.now.wday @date = Date.current @time = DateTime.now.hour if downtime errors.add(:_, "Please submit your request during working hours") end end def downtime holidays || @time < 9 || @time > 17 || @day == 6 || @day == 0 end
Thanks a lot! |
| Countdown timer with Javascript/JQuery in rails application Posted: 12 Mar 2016 06:56 AM PST What I would like to do is basically something like this: 1.Users sign up/ log in. OK 2.They create a new countdown and share it. NOPE 3.Other people just subscribe by email to the user. OK
In the second point I am not really having a clear thought on how I can implement countdown timer creation and deletion. The creation part should be something like in this site: http://www.timeanddate.com/countdown/create If anyone can give any direction on how to do this implementation on a rails app please do. |

| Better practice to modularize code in mixins? Or just put all the code directly into the model? Posted: 12 Mar 2016 06:21 AM PST The title kind of says it all. I prefer to modularize code into mixins and include them into the model. My coworkers like to put the code directly into the model, potentially growing our model to MOUS's, models of unusual size. They think mixins are overkill. I'm wondering what you guys do/what's better practice out there in dev land. |
| Ruby on Rails Dashboard partials Posted: 12 Mar 2016 05:52 AM PST I want to make a task-dasboard, but I have a few problems. What I want to achieve: I want to show multiple partials on one page, that respond to eachother. When you go to the dashboard you have two columns. The first column shows you the lists with all tasks and the second column shows you the details of one of the tasks you have clicked on in the first column (or automaticly the last made task in the list) Image to visualise what I want to achieve: https://gyazo.com/e87acf214e255817cdb03a22e3a35c4d At this moment my files look like this: application.html.erb <div class="main-content"> <section id="tasks"> <div class="wrapper"> <%= render partial: 'task_lists/index', collection: @task_lists %> </div> </section> <section id="description"> <%= render partial: 'task_lists/show', collection: @task_lists %> </section> <%= yield %>
The <%= render partial: 'task_lists/index', collection: @task_lists %> already works so every task is listed in one column. The problem is that <%= render partial: 'task_lists/show', collection: @task_lists %>, doesn't work. This is the _show.html.erb where the 'broken' partial links to: <div class="row"> <div class="task_image"> <img src="../images/phone_img.png"></img> </div> <div class="task_heading"> <h1><%= @task_list.title %></h1> <p class="user_info">For <%= @task_list.client_email %></p> </div> <div class="task_content"> <%= render @task_list.task_items %> </div> <div class="task_finish"> <div class="row"> <p>Finish task</p> </div> </div>
When I run the project, Rails says that the ID is undifined in the file _show.html.erb. My question: How can I make that Rails automaticly picks the first task unless someone clicked on a other task? So when you come on the dashboard you see the tasklist in the first column and Rails automaticly picks the first task and shows the details of it (_show.html.erb) in the second column. When you click on a other task in the first column you will get to see the details of that task in the second column. I hope my question is clear, ohterwise let me know. Thanks in advance. |
| Using ruby on rails variables with Highchart Posted: 12 Mar 2016 06:29 AM PST I'm trying to create a column chart in my ruby on rails app. I have the basic graph set up, but for some reason I can't figure out how to dynamically change the data in my graph by using the variables i have created. <script type="text/javascript" charset="utf-8"> $(function () { new Highcharts.Chart({ chart: { renderTo: 'progress_chart', type: 'column'}, title: { text: 'My Weekly Progress' }, xAxis: { categories: ['Activity 1', 'Activity 2', ' Activity 3'], crosshair: true }, yAxis: { min: 0, max: <%=$extra%> , title: { text: 'Weeks' } }, tooltip: { headerFormat: '<span style="font-size:10px">{point.key}</span><table>', pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' + '<td style="padding:0"><b>{point.y:.1f} mm</b></td></tr>', footerFormat: '</table>', shared: true, useHTML: true }, plotOptions: { column: { pointPadding: 0.2, borderWidth: 0 } }, series: [{ name: 'Submitted', data: [<%= @submitted_array %>] }, { name: 'Approved', data: [83.6, 78.8, 98.5] }, { name: 'Weeks left', data: [48.9, 38.8, 39.3] }] }); }); </script>
At the moment I am just trying to set the max of the yAxis to equal the variable $extra, but this doesn't seem to work. I am also trying to set the data for 'Submitted' to equal the following array which has been created within my controller: def show @submitted_array = $submitted1.to_s + ", " + $submitted2.to_s + ", " + $submitted3.to_s end
Have I got incorrect syntax? Or am I calling my variables incorrectly? |

| Referring another model's method from current model's view Posted: 12 Mar 2016 05:55 AM PST I'm pretty new to Rails. I'm working on an app where you can upload a csv file or create a manual bank transaction. Previously I had both the manual entry and uploaded csv file entries in a single table called Transaction. Now I'm trying to store the uploaded file entries in a separate table called Bank. So I have a Bank model and a Transaction model and their respective controllers & views. Previously I had "New Transaction" form and "Upload CSV" form in the same page called "New Transaction" to avoid creating separate views for both and it was working fine. Now, After I've created a new model(Bank) for CSV uploaded entries, I tried to refer the Bank model's import method path from my "New Transaction" page to import csv files. But its returning me a Load Error. LoadError in BanksController#new Unable to autoload constant BanksController, expected /app/controllers/banks_controller.rb to define it
This is my Bank Model: class Bank < ActiveRecord::Base belongs_to :admin paginates_per 10 def self.to_csv(options = {}) CSV.generate(options) do |csv| csv << column_names all.each do |transaction| csv << transaction.attributes.values_at(*column_names) end end end extend ActiveModel::Model include ActiveModel::Validations include ActiveModel::Conversion attr_accessor :file validates :date, presence: true validates :notes, presence: true validates :t_type, presence: true validates :t_method, presence: true validates :amount, presence: true validates :paid_by, presence: true validates :paid_to, presence: true #validates :cashbox, presence: true validates :bank, presence: true def self.import(file) CSV.foreach(file.path, headers: true) do |row| transaction_hash = row.to_hash t = Bank.new(transaction_hash.except("cashbox")) t.id = Bank.maximum(:id).next t.save! end end end
This is my Bank Controller: class BankController < ApplicationController before_filter :authenticate_admin! def index @banks = Bank.all.order('created_at DESC') respond_to do |format| format.html format.csv { send_data @banks.to_csv } end end def import begin Bank.import(params[:file]) redirect_to root_url, notice: "Transactions Imported!" rescue ActiveRecord::RecordInvalid => exception redirect_to :back, alert: "#{exception.message}" end end def editview @q = Transaction.ransack(params[:q]) respond_to do |format| format.html format.csv { send_data @transactions_list_for_csv.to_csv, filename: 'transactions.csv' } end end end
This is my New Transaction View from transaction model where it contains both forms for new transaction and upload csv: <div class="col-md-6"> <div class="container new-container"> <h3>New Transaction</h3> <%= render 'form' %> </br> <%= link_to "Back", root_path %> </div> </div> <div class="divider"></div> <div class="col-md-6"> <div class="import-col"> <h3>Import a CSV File:</h3> <%#= form_tag import_transactions_path, multipart: true do %> <%= form_tag import_banks_path, multipart: true do %> <%= file_field_tag :file, class: "form-control", required: true %></br> <%= submit_tag "Import CSV", class: "btn btn-success" %> <% end %> </div> </div>
This is Transactions controllers new method: def new @transaction = Transaction.new end

| Nested Views with Dynamic Id's Angular & Rails Posted: 12 Mar 2016 05:39 AM PST Hey I have Angular rendering a list of Quotes as resources. The Quotes are stored in a rails back end. I am at the point where I would like to use Angular to render the show.html for that specific quote resource. I havent been able to get angular to resolve to the state. I'm not sure if I understand how to pass id's into state. I need help figuring out how to get angular to render the show.html in the ui-view labeled "fullquote" for the specific quote.

| Rails custom fonts Posted: 12 Mar 2016 04:01 AM PST After following this guide I'm still not able to use my custom font in my Rails application. This is my new Assets file structure: |-app/ |---assets/ |-----fonts/ |-----images/ |-----javascripts/ |-----stylesheets/ In the fonts directory I placed a file named: "Hurme Design - HurmeGeometricSans3 Regular" I edited my config/application.rb which now looks like so: require File.expand_path('../boot', __FILE__) require 'rails/all' # Require the gems listed in Gemfile, including any gems # you've limited to :test, :development, or :production. Bundler.require(*Rails.groups) module Criteofootball class Application < Rails::Application config.assets.paths << Rails.root.join("app", "assets", "fonts") # Settings in config/environments/* take precedence over those specified here. # Application configuration should go into files in config/initializers # -- all .rb files in that directory are automatically loaded. # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone. # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC. # config.time_zone = 'Central Time (US & Canada)' # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded. # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s] # config.i18n.default_locale = :de end end
In my scss file I wrote the following in order to apply the font to all my HTML elements: @font-face { font-family: "Hurme Design"; src: font-url(Hurme Design - HurmeGeometricSans3 Regular); } html * { font-family: "Hurme Design" !important; }
Thanks a lot in advance! |
| SQLite3 error in rails SQLite3::SQLException: no such column Posted: 12 Mar 2016 06:07 AM PST I am making a rails app where a user can post courses and also subscribe to courses.My model files are:

end The coursejoin model is like a relation between a course and a user.
When I try to do @course.students, i get error: SELECT "users".* FROM "users" INNER JOIN "coursejoins" ON "users"."id" = "coursejoins"."student_id" WHERE "coursejoins"."course_id" = ? [[nil, 1]] ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: coursejoins.course_id: SELECT "users".* FROM "users" INNER JOIN "coursejoins" ON "users"."id" = "coursejoins"."student_id" WHERE "coursejoins"."course_id" = ?
I don't know SQL much so I am not able to decipher the error.
I looked at questions with similar error but none seemed related.
I have been stuck with this for two days.
How do I fix this? |
| Rails referral marketing on discount Posted: 12 Mar 2016 03:45 AM PST I am trying to build a referral marketing system on rails. Searched on various web pages for information could not find any helpful content. What I would like to do is, I have created a user model, who can sign in - out OK. Then they can type a email address to text_field to send a email to friends saying "come join us" etc. The referred user clicks to link come backs to site when he signs up to site, I will give a discount for instance. For the sake of clarity lets say the main user's email address is jack@gmail.com, who wants to send to his friend alex@gmail.com. Alex receives and email "come join us". He clicks and signs up, and gets discount. How can I know that Alex clicked on the link and signed up. I should be generating some come attached to the link in the email address but not sure how to do it. Thank you for your help! |
| rails - HasManyThroughAssociationNotFoundError on plural has_many Posted: 12 Mar 2016 06:04 AM PST I have the following models: User Team UserTeam
There are users and there are teams. Each team has 0 or more users, the join table is UserTeams I want to get all teams and for each team get its users. Initially I tried for one team and get its users, like this Team.find('759ccbb7-2965-4558-b254-3e437ca721aa').users
but rails complains about this with: Could not find the association :user_team in model Team
This is how my Team model looks like: class Team < ActiveRecord::Base has_many :users, through: :user_team has_many :user_teams, dependent: :destroy accepts_nested_attributes_for :user_teams, :reject_if => lambda { |a| a[:user_id] == '0' } validates :name, presence: true end
Team model: class UserTeam < ActiveRecord::Base belongs_to :team belongs_to :user validates :user_id, presence: true end
Weird enough, if I change Team model like this: has_many :user_team
using the singular word, it works, but I read that it has to be pluralized |

| Using Turbolinks without asset pipeline? Posted: 12 Mar 2016 02:07 AM PST I am building a Rails 5 webapp around a premade HTML5 template. I would like to use Turbolinks as it would heavily complement the purposes of the application. However, I chose not to use the Rails asset pipeline because everything in the HTML/CSS files of the template is statically linked with absolute paths. The turbolinks documentation specifies an entry to be made in the Javascript manifest. However, will it still work if nothing else is being processed by the asset pipeline? |
| How to stub searchkick in search method in controller Posted: 12 Mar 2016 01:31 AM PST I am new to rspec and I want to test my search controller, I try to stub my search method in controller but it always fails.

And here is my controller test: context 'with keyword' do let(:search_param) { "rizky" } let(:doctor) { instance_double(Doctor) } let(:results) { instance_double(Searchkick::Results) } before do allow(Doctor).to receive(:search).with(search_param) {:results} end it 'calls Doctor.search' do get :search, search_param expect(Doctor).to receive(:search).with(search_param) end end

| data attribute returns duplicated array #rails Posted: 12 Mar 2016 12:49 AM PST So I have a link that has data passed into it. I access that data from the click function in jquery. But when I alert the data objects, it alerts the first object twice. I don't know why it does that. I printed the size of the data and it said 2.
