| Rails, Ajax, jQuery - Can't make to render changes without page refresh Posted: 11 Nov 2016 07:45 AM PST I'm using Ajax and jQuery to display changes after user adds products to cart. I use it in two places and one is working fine - when user on products page, after he adds product I display number of added products and total price in navbar (using create action) But cant make same feature on Cart page - there users can increase or decrease number of products (using increase and decrease actions) App models: Cart has_many :line_items Product has_many :line_items LineItem belongs_to :cart, belongs_to :product This works fine application.html.erb: <%= link_to @cart do %> Your cart: <i class="glyphicon glyphicon-shopping-cart"></i> <span id="number"><strong><%= @cart.line_items.map { |i| i[:quantity] }.sum %></span></strong> pcs. Total: <span id="price"><strong><%= number_to_currency(@cart.line_items.map { |i| i.total_price }.sum, :unit => "€", separator: ",", format: "%n %u") %></strong></span> <% end %>
create.js.erb (in views/line_items folder): $('#notice').hide(); $('#number').html("<strong><%= @cart.line_items.map { |i| i[:quantity] }.sum %></strong>") $('#price').html("<strong><%= number_to_currency(@cart.line_items.map { |i| i.total_price }.sum, :unit => "€", separator: ",", format: "%n %u") %></strong>")
line_items_controller.rb: def create product = Product.find(params[:product_id]) @line_item = @cart.add_product(product) respond_to do |format| if @line_item.save format.html { redirect_to :back } format.js format.json { render :show, status: :created, location: @line_item } else format.html { render :new } format.json { render json: @line_item.errors, status: :unprocessable_entity } end end end

This does not work: _line_item.html.erb (rendering this into _cart.html.erb): <tbody> <...> <td data-th="Quantity"> <span id="number"><%= line_item.quantity %></span> </td> <...> <td><%= link_to "-", decrease_line_item_path(product_id: line_item.product), remote: true %></td> <td><%= link_to "+", increase_line_item_path(product_id: line_item.product), remote: true %></td> </td> </tr> </tbody>

| Rails: Ransack Gem using dropdown - "undefined method name" error Posted: 11 Nov 2016 07:36 AM PST I am using the Ransack gem to create a filter form for my table. In my controller (I am taking the filter options from another table): homeworks_controller: ... @q = Homework.search(params[:q]) @sub = Homework.find_by_sql("SELECT subject FROM classmodules GROUP BY subject").map &:subject @q.build_condition if @q.conditions.empty? @q.build_sort if @q.sorts.empty? ...
In my view <%= search_form_for @q do |f| %> <%= f.select :subject_eq, @sub %> <%= f.submit %> <% end %>
Models classmodule.rb has_many :homeworks, :class_name => 'Homework' homework.rb belongs_to :classmodule, :class_name => 'Classmodule', :foreign_key => :subject
I get "undefined method `name' for nil:NilClass" as an error. I searched for an answer but nothing solid for this and tried some suggested solutions. I'm stuck, any ideas? Thanks |
| static error pages from an engine Posted: 11 Nov 2016 07:25 AM PST I have an engine I'm using in a suite of apps to share assets, layout, MVCs and helpers. I'd like to add error pages to that list, what's the easiest way to go about this for static pages? Ideally, I'd like each app using the engine to serve up the error pages in my engine's public/ rather than the main app's public/. |
| Two step confirmation with Devise 4.2 and Rails 5 Posted: 11 Nov 2016 07:23 AM PST I'm developing an rails API and I'm facing the problem of making, with devise and devise_token_auth a two steps confirmation for user registration specified here. To put more context in this post, what I'm trying to accomplish is give the ability to create a standard user by an admin only inputing the user email, and then sending an email to with an URL with a confirmation token in it so he then input his password and password confirmationm so he can finally finish creating the user. So it appears that the documentation specified in the post from above isn't too much updated as the most updated post is for Rails 4 with Devise 3.X. I'm using Rails 5 and Devise 4.2, not totally sure if that affects something, but I tried to do what specified and, of course, didn't work. I'll be glad to hear some advices on this. I've been researching and there's not too much documentation about it, also because I have the complexity of using devise_token_auth, not only devise. |
| get the latest version from an array in ruby Posted: 11 Nov 2016 07:46 AM PST I have an array of version numbers called unique_versions that keeps on increasing : 1.7.16 1.7.14 1.7.13 1.7.12 1.7.9 1.7.7 1.7.5 1.7.4 1.7.2 1.6.2 1.2.1 1.2.0 1.1.0 0.0.1
and I need to get the latest(1.7.16) from the array. What the most elegant ruby way of doing it ? I get this array by the following code : require "json" require "open-uri" require 'openssl' string_object = open("https://xxx", :http_basic_authentication=>["xxx"], :ssl_verify_mode=>OpenSSL::SSL::VERIFY_NONE) json_file = JSON.parse(string_object.read) version_array = Array.new json_file["results"].each do |version| version_array.push(version["version"].sub /-.*$/, '') end unique_versions=(version_array.uniq)

| Rails nested form with unknown columns Posted: 11 Nov 2016 07:03 AM PST I'm creating an admin interface where the admin (of a company) can add custom fields to their employees. Example: Models: - Employee: Basic info like name, contact info, etc (has_many employee_field_values)
- EmployeeFields: These are the dynamic ones the admin can add (every company has different needs, it could be anything), lets say
favorite_food - EmployeeFieldValues: The actual values based on the fields above, say
pizza (belongs_to both models above) What's a smart way of adding the EmployeeFieldValues fields while editing an employee? I'm trying something simple like this, but not sure if I like it # Controller @custom_fields = EmployeeFields.all # View <%= form_for(@employee) do |f| %> <%= f.text_field :first_name %> <% @custom_fields.each do |custom_field| %> <%= custom_field.name %> <%= text_field_tag "employee_field_values[#{custom_field.name}]" %> <% end %> <%= f.submit :save %> <% end %>
And then when updating, params[:employee_field_values] gives this: <ActionController::Parameters {"favorite_food"=>"pizza"}>
So, not sure if this is a good direction, also I'm not sure how to handle future edits to an employee's custom_fields if they change. |

| NoMethodError - Calculation in Rails Model Posted: 11 Nov 2016 06:49 AM PST I have an item model. In that model I need to be able to calculate the profit of a product. However, if I just bought that item it obviously has not been purchased yet and the values for sold_for, fees, and shipping will be empty. If there are no values entered I get a undefined method-' for nil:NilClasserror. I triedrescue NoMethodError`, but then it would not calculate the profit. Is there a way to avoid the error and also have my calculation work? items.rb class Item < ActiveRecord::Base def profit_calc sold_for - bought_for - fees - shipping end def self.purchase_total sum(:bought_for) end def self.fee_total sum(:fees) end def self.shipping_total sum(:shipping) end def self.sales_total sum(:sold_for) end def self.profit_total sum(:sold_for) - sum(:bought_for) - sum(:fees) - sum(:shipping) end scope :visible, -> { where(sold: false) } scope :sold, -> { where(sold: true) } end

| Search logic in ruby on rails 4.0 Posted: 11 Nov 2016 07:43 AM PST Well when we are implementing simple search its something like (searching for a song): Model: def self.search(query5) where("name LIKE ? ","%#{query5.downcase}%") end
but when the query is something like James TW when you love someone and the name of the song is when you love some James TW it doesnt return anything. So what do I do about that hat the correct logic for that? |
| @user.reload not working as expected (change the year to 2000) Posted: 11 Nov 2016 06:57 AM PST Hi I`m following the Michael Hartl tutorial and I came across strange behaviour. In chapter 12 Password reset, password_reset_controller, create action looks like this: def create @user = User.find_by(email: params[:password_reset][:email].downcase) if @user @user.create_reset_digest @user.send_password_reset_email flash[:info] = 'Email sent with password reset instructions' redirect_to root_url else flash.now[:danger] = 'Email address not found' render 'new' end end
And the create_reset_digest method looks like this: def create_reset_digest self.reset_token = User.new_token update_attribute(:reset_digest, User.digest(reset_token)) update_attribute(:reset_sent_at, Time.zone.now) end
I used a byebug to monitor changes and came across a strange thing: When I try byebug at the end of the create action I got this result: #<User id: 762146111, ..., reset_sent_at: 2016-11-11 13:47:00 UTC>
But when I try to see what was saved after @user.reload, I get: #<User id: 762146111, ..., reset_sent_at: "2000-01-01 13:47:00">
Why is the attribute reser_sent_at switching to year 2000-01-01? |
| Deprecation Warning About Mass Assignment Rails 4.0 Posted: 11 Nov 2016 05:50 AM PST I am upgrading an app to 4.0 and using ruby-2.2.5. I am down to a couple of Deprecation Warnings, which appear when I run >> bundle exec rake. One of the warnings: DEPRECATION WARNING: Model based mass assignment security has been extracted out of Rails into a gem. Please use the new recommended protection model for params or add `protected_attributes` to your Gemfile to use the old one. To disable this message remove the `whitelist_attributes` option from your `config/application.rb` file and any `mass_assignment_sanitizer` options from your `config/environments/*.rb` files. See http://guides.rubyonrails.org/security.html#mass-assignment for more information.
I understand what this about and I have gone through all my models looking for and removing 'attr_accessible'. I have gone through all my controllers and added a method for strong_params, which I call in my 'create' and 'update' actions. We are not using 'whitelist_attributes' or any 'mass_assignment_sanitizer' options. And, all my spec tests are passing. My Questions is, Would this warning be just a standard output or would it be from rails seeing something I am not? Ideas? Much appreciated |

| How to reference an image within HTML tag in Rails 4 Posted: 11 Nov 2016 04:29 AM PST I understand that rails assets eg. an image in assets/images/ get a cache helper number appended to them ie. background.jpg may become background77bfb376c1e.jpg and therefore, a helper must be used to reference them e.g. asset-url("background.png", image)
However.. How could I reference background.jpg in a HTML tag such as this: <header class="pt100 pb100 parallax-window-2" data-image-src="background.jpg">

| Rails. Undefined method `remove_product' for nil:NilClass Posted: 11 Nov 2016 04:04 AM PST App models: Cart has_many :line_items Product has_many :line_items LineItem belongs_to :cart, belongs_to :product If the same product being added in the cart multiple times, I count that number in cart.rb: def add_product(product) current_item = line_items.find_by(product_id: product.id) if current_item current_item.quantity += 1 else current_item = line_items.build(product_id: product.id) end current_item end

This is my trivial partial, where @box is the list of all received or sended messages (set via controller) <div class="container-full"> <div class="mailbox"> <div class="caption"> <% if @box.blank? %> Non ci sono messaggi <span id="inout"></span> <% else %> Ci sono <%= @box.count %> messaggi <span id="inout"></span> <% end %> </div> <table class="table"> <caption> Messaggi <span id="inout"></span></caption> <thead> <tr> <th> <span id="invric"></span> da </th> <th> Data di invio </th> <th> messaggio </th> </tr> </thead> <tbody><% if !@box.blank? %><% @box.each do |m| %> <tr> <td id="mailselector"></td> <td> <%= m.updated_at.to_formatted_s(:short) %> </td> <td> <%= m.mex[0, 30] %><span>...</span> </td> </tr> <% end %> <% end %> </tbody> </table> </div> </div>

| Writing test on generated text Posted: 11 Nov 2016 03:29 AM PST I'm replacing words in a piece of content with a rails helper to add tooltips. No problem at all and working fine, but i would like to test this helper on the exact output and because the replacement adds some unwanted formatting i find it hard to really test this helper. original string a piece of <a href="http://">content</a> that contains jargon1 to be replaced
my helper replaces jargon1 with some html to render a tooltip content.gsub!(/#{jargon.word}/i, get_node(jargon)) def get_node jargon <<-HTML <a href='#jargon-#{jargon.id}' class='jargon-tip' data-toggle='tooltip' data-placement='top' data-original-title='#{jargon.desc}' rel='help'>#{jargon.word}</a> HTML end
result of the string with the injected html a piece of <a href="http://">content</a> that contains <a href='#jargon-130' class='jargon-tip' data-toggle='tooltip' data-placement='top' data-original-title='desc for jargon 1' rel='help'>jargon1</a> to be replaced
First of all there are 7 spaces between that contains and <a and i would like the html to display inline in the result but in my code i like it formatted like above to keep it readable. My end goal would be to build a robust test on comparing the parsed string to a pre defined string. For now i only test on a piece of the string (expect(result).to include("data-original-title='desc for jargon 1'")) because of formatting issues with \n and it going to be a fragile test. Thanks in advance! |

| Rails validate format with regex Posted: 11 Nov 2016 02:29 AM PST In my rails app, I want to validate input on a string field containing any number of keywords (which could be more than 1 natural language word (e.g. "document number")). To recognize the individual keywords, I am entering them separated by ", " (or get their end by end of string). For this I use validates :keywords, presence: true, format: { with: /((\w+\s?-?\w+)(,|\z))/i, message: "please enter keywords in correct format"}
It should allow the attribute keywords (string) to contain: "word1, word2, word3 word4, word5-word6" It should not allow the use of any other pattern. e.g. not "word1; word2;" It does incorrectly allow "word1; word2" On rubular, this regex works; yet in my rails app it allows for example "word1; word2" or "word3; word-" where is my error (got to say am beginner in Ruby and regex)? |
