| rails4 behavior based on link_to is nil Posted: 08 Jun 2016 07:01 AM PDT There is a website attr on product_lead table which is optional. If it's present then I wanna turn @produc_lead.lead into a link, but if it's not it should be plain text. If I use the code below and the website is nil then the link points to the page the user is currently on. If I do it with @product_lead.try(:website), it's gonna be the same. But as I mentioned I would like to have plain text over link in this case. <%= link_to @product_lead.website, target: "_blank" do %> <%= @product_lead.lead %> <% end %>
After playing around I fell back to the following solution, but it's terrible. Any better ideas? <% if @product_lead.website %> <%= link_to @product_lead.website, target: "_blank" do %> <%= @product_lead.lead %> <% end %> <% else %> <%= @product_lead.lead %> <% end %>

| How to create has_many association with "includes" and "where" conditions Posted: 08 Jun 2016 06:53 AM PDT Here is the situation: a store has many products, and can join multiple alliances. But the store owner may not want to display certain products in some alliances. For example, a store selling computers and mobile phones might want to display only phones in a "Phone Marts". By default, all products in the store will be displayed in all alliances one shop joins. So I think building a product-alliance blacklist (I know it's a bad name...any ideas?) might be a convenient way. The question is: how to create a "has_many" to reflect such relations like the behaviours of function shown_alliances and shown_products? I need this because Car.includes(:shop, :alliances) is needed elsewhere, using functions make that impossible. Product: class Product < ActiveRecord::Base belongs_to :store has_many :alliances, -> { uniq }, through: :store has_many :blacklists def shown_alliances alliances.where.not(id: blacklists.pluck(:alliance_id)) end end
Store: class Store < ActiveRecord::Base has_many :products has_many :alliance_store_relationships has_many :alliances, through: :alliance_store_relationships end
Alliance: class Alliance < ActiveRecord::Base has_many :alliance_store_relationships has_many :store, through: :alliance_store_relationships has_many :products, -> { uniq }, through: :companies has_many :blacklists def shown_produtcts @produtcts ||= produtcts.where.not(id: blacklists.pluck(:produtct_id)) end end
Blacklist: class Blacklist < ActiveRecord::Base belongs_to :produtct belongs_to :alliance validates :produtct_id, presence: true, uniqueness: { scope: :alliance_id } end

However I will need two profiles within the system. User and Professional. User = devise basic information Profisssional = will have to add various informations. What better way to create these different profiles? with a boolean in the model User = 0 User, 1 Professional. or creating more 1 devise model? or Another way Remembering that I'll need to list (array) the registered professional later. |
| render two different model errors in JSON Posted: 08 Jun 2016 06:40 AM PDT I have a remote form, that essentially submits two forms in one. One for Address the other for User now what I'd like to do is render the errors in JSON. I'm able to return the errors individually like this: if current_user.errors.any? || !@address.save respond_to do |format| format.json { render json: @address.errors, status: :unprocessable_entity } end end
now there's the case where they trigger an error on both User model and Address. How can I render both errors so @address.errors and current_user.errors. I've tried to merge them as hashes, but as they belong to ActiveModel::Errors it's unable to do so. An error usually returns like this if you inspect it: #<ActiveModel::Errors:0x007fbe094edda0 @base=#<Address id: nil, street_address: "Lorem ipsum", city: nil, state: nil, zip_code: "0000", country: nil, user_id: 1, created_at: nil, updated_at: nil, latitude: 10.92876, longitude: 52.23023, trashed: false>, @messages={:zip_code=>["No zip code matches this"]}, @details={:zip_code=>[{:error=>:inclusion, :value=>"0000"}]}>
so what I'm trying to figure out is if there's a way to merge this into one, so I can just return that. |

| Disable enforce utf8 in a redmine form Posted: 08 Jun 2016 05:57 AM PDT I have a redmine installation running fine. I have an issue to disable the utf-8 enforcement tag when doing searches.

| Prerendering React Components With React Rails Posted: 08 Jun 2016 05:18 AM PDT I have a simple React component that is currently rendering correctly on the client. I am trying to have it render on the server. To test this I am switching off the JavaScript in Chrome and loading the page. My component looks like this: window.TestComponent = React.createClass({ render: function() { return React.DOM.h1({className: 'TestComponent'}, 'Test Component') } });
The entrypoint looks like this: <%= react_component 'TestComponent', {prerender: true} %>
At the moment, the page loads without error and contains the following: <div data-react-class="TestComponent" data-react-props="{'prerender': true}"></div>
It seems that Rails is parsing the erb, but fails to render the component it references. I have included The Ruby Racer in my Gemfile and have verified it is working by printing out some calculations to the DOM. According to the React Rails docs on server-side rendering there are three requirements: Requirement 1 react-rails must load your code. By convention, it uses components.js, which was created by the install task. This file must include your components and their dependencies (eg, Underscore.js). My component is located in: app/assets/javascripts/components/test_component.js.erb and should be loaded by the JavaScript in components.js: //= require_tree ./components
Requirement 2 Your components must be accessible in the global scope. If you are using .js.jsx.coffee files then the wrapper function needs to be taken into account: I am using plain JavaScript Requirement 3 Your code can't reference document. Prerender processes don't have access to document, so jQuery and some other libs won't work in this environment :( I don't reference document. What might I be doing wrong? |

| How to save ids to users columns Posted: 08 Jun 2016 05:46 AM PDT So I've built a system of products and a shopping cart in my rails app. The goal I have is to add ids of the saved products from a cart to the user model. So in my cart view page there is a list of all added products in a cart and I want to add a save button which will save those products by their ids to the columns in users table. As an example, if current_user ads three products in the cart with ids 1,2,3 and clicks on "Save" button in a cart, I want to be able to save those three ids by integers to the three columns: product_one, product_two, product_three of the current_user. So far these are my models: class Item < ActiveRecord::Base has_one :cart end class User < ActiveRecord::Base has_one :cart has_many :items, through: :cart end class Cart < ActiveRecord::Base belongs_to :user belongs_to :item validates_uniqueness_of :user, scope: :item end
My controllers: class ItemsController < ApplicationController before_action :set_item, only: [:show, :edit, :update, :destroy] respond_to :html, :json, :js def index @items = Item.where(availability: true) end def show end def new @item = Item.new end def edit end def create @item = Item.new(item_params) @item.save respond_with(@item) end def update @item.update(item_params) flash[:notice] = 'Item was successfully updated.' respond_with(@item) end def destroy @item.destroy redirect_to items_url, notice: 'Item was successfully destroyed.' end private def set_item @item = Item.find(params[:id]) end def item_params params.require(:item).permit(:name, :description, :availability) end end
my cart controller: class CartController < ApplicationController before_action :authenticate_user!, except: [:index] def add id = params[:id] if session[:cart] then cart = session[:cart] else session[:cart] = {} cart = session[:cart] end if cart[id] then cart[id] = cart[id] + 1 else cart[id] = 1 end redirect_to :action => :index end def clearCart session[:cart] = nil redirect_to :action => :index end def index if session[:cart] then @cart = session[:cart] else @cart = {} end end end

| Devise 'Unpermitted parameter: email' Posted: 08 Jun 2016 04:42 AM PDT I'm using devise with cancancan and rails_admin. On signing in the admin model, I get the following error. Unpermitted parameter: email
admin model was generated by devise using rails g devise Admin
I tried overriding the controller and here's my admin/registrations_conroller.rb class Admin::RegistrationsController < Devise::RegistrationsController before_action :configure_devise_permitted_parameters, if: :devise_controller? protected def configure_permitted_parameters devise_parameter_sanitizer.for(:account_update).push(:email) if params[:action] == 'update' devise_parameter_sanitizer.permit(:account_update) { |u| u.permit(registration_params << :current_password) } elsif params[:action] == 'create' devise_parameter_sanitizer.permit(:sign_up) { |u| u.permit(registration_params) } end end # def new # super # end # def create # super # end end
Here's my admin model class Admin < ActiveRecord::Base # Include default devise modules. Others available are: # :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable validates :email, presence: true end
My ability.rb class Ability include CanCan::Ability def initialize(admin) admin ||= Admin.new # guest user (not logged in) if admin.position? :superadmin can :manage, :all else can :read end end end
My config/initializers/rails_admin.rb RailsAdmin.config do |config| ## == Devise == config.authenticate_with do warden.authenticate! scope: :admin end config.current_user_method(&:current_admin) ## == Cancan == config.authorize_with :cancan config.actions do dashboard # mandatory index # mandatory new export bulk_delete show edit delete show_in_app ## With an audit adapter, you can add: # history_index # history_show end end
And finally my admins table create_table "admins", force: :cascade do |t| t.string "email", default: "", null: false t.string "encrypted_password", default: "", null: false t.string "reset_password_token" t.datetime "reset_password_sent_at" t.datetime "remember_created_at" t.integer "sign_in_count", default: 0, null: false t.datetime "current_sign_in_at" t.datetime "last_sign_in_at" t.string "current_sign_in_ip" t.string "last_sign_in_ip" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.string "position" end
What I'm trying to do is have a position column in the admins table which specifies the type of admin i.e. superadmin, moderator etc. |

I ended up removing & reinstalling mysql via homebrew in order to fix issues. I managed to recover the enviroments of all my php projects but not this one. running ps aux | grep mysql returns: myuser 19131 0,0 0,1 3570856 6428 ??

When i try to run rake db:create i get the following error: rake aborted! uninitialized constant Mysql2::Client::SECURE_CONNECTION
mysql.server status seems to be running.. when i try to stop (mysql.server stop) i get: Shutting down MySQL .. ERROR! The server quit without updating PID file (/usr/local/var/mysql/macbook.local.pid).
And mysql continue to run but with a new pid id . Any idea whats wrong with the rails project and how to approach it? Thanks, C |
| Need to genrate bills for all users in rails, what should be create method? Posted: 08 Jun 2016 04:11 AM PDT Hi, I need to generate bills for all users (residents) in my app, the bill_controller's create method looks like : def create resident = Resident.find_by(hostel:current_admin_user.hostel) # current_admin_user action is provided by Activeadmin to access current activeadmin user details @bill=resident.bills.create(bill_params) if @bill.save flash[:info] = "Bills Generated successfully" redirect_to new_bill_path else flash[:danger] = "Bills Not generated, Please try again!" redirect_to new_bill_path end end
The active admin users can generate bills, and bills will be generated only for residents that have same hostel with admin user ! And bills should be generated for all residents with specific hostel. check out my code, right now it is generating only for current user(resident logged in) . thanks ! |
| Select tag doesn't display on my form Posted: 08 Jun 2016 03:42 AM PDT I'm writing a really simple form with 2 text fields and one select. For some reason, the select tag with options doesn't display on my page. I can see the 2 text fields and the label for the the select, but not the select it self. The app is written in rails and I use materialize. There might be something too obvious that I don't see it, but after 30mn of thinking, I guess it's fair to put it on SO :) Thanks Here's the code: <form action="/resources" method="post"> <input type="hidden" name="authenticity_token" value="<%= form_authenticity_token %>"> <label for="ressource_name">Ressource Name</label> <input type="text" id="ressource_name" name="resource[ress_name]" value="<%= @resource.ress_name %>"> <label for="ressource_link">Ressource Link</label> <input type="text" id="ressource_link" name="resource[link]" value="<%= @resource.link %>"> <label for="categories">Categories</label> <select id="categories" name="resource[category_id]"> <option value="1">Stuff 1</option> <option value="2">Stuff 2</option> <option value="3">Stuff 3</option> <option value="4">Stuff 4</option> <option value="5">Stuff 5</option> <option value="6">Stuff 6</option> <option value="7">Stuff 7</option> <option value="8">Stuff 8</option> </select> <br> <input type="submit" value="Post"> </form>

| Ammend changes to previous Capistrano 3 release Posted: 08 Jun 2016 03:24 AM PDT Hello Ruby and web programmers! In the company where I work, we are currently developing a web application with Ruby on Rails. For production deployments, we use Capistrano 3. The production deploys will be performed like this: 1. The desired features are implemented. 2. Those features are tested in a test environment (staging). 3. When and all features have been refined and approved, they are deployed to production (basically with `cap production deploy`).
The Deploys are performed every 1 or 2 weeks. Thus, suppose that in one month, the following releases are generated: 1. Release nº1 (deploy, week 1) 2. Release nº2 (deploy, week 2) 3. Release nº3 (deploy, week 4)
Now if in week No. 3 we'd found a critical bug, the release history will look like this: 1. Release nº1 (deploy, week 1) 2. Release nº2 (deploy, week 2) 3. Release nº3 (hotfix, week 3) 4. Release nº4 (deploy, week 4)
My question is: is there any way to ammend or patch changes to the previous version (in this case, *Release No 2*without rollback? We've taken a look at capistrano-patch, but it seems too complex for what we look for solution. Thanks in advance! |

| Credit card number is stored as a plain text while using Activemerchant gem with paypal integration Posted: 08 Jun 2016 02:58 AM PDT I am working on a maintenance project which is in Rails 3.2.3. Here for payments they are using Active Merchant gem for Paypal integration. As per the code review I did, mostly the code is written based on this railscast. When I enter a credit card number, it is saved as a plain text. Does Active Merchant have any mechanism to encrypt this card number? or Is there any way to store this card number as either "xxxx-xxx-xxx-xxxx" or encrypted? |
