| Rails search form throwing back error Couldn't find Product with 'id'=search Posted: 24 Jun 2016 07:56 AM PDT I'm building an rails app to learn ruby on rails.(I'm very unexperienced) I'm trying to implement a search bar to the app. When I hit search rails throws back this error Couldn't find Product with 'id'=search in this line # Use callbacks to share common setup or constraints between actions. def set_product @product = Product.find(params[:id]) end I've been working on this search form for hours and checked out various tutorials and stackoverflow posts trying to figure this out. I'm totally lost but the solution is probably pretty simple. Please can anyone help me. this is my search form in _navbar.html.erb <div class="input-group"> <%= form_tag search_products_path, method: 'get', class: 'navbar-form' do %> <%= text_field_tag :query, params[:query], placeholder: "Search", class: "form-control"%> </div> <span class="input-group-btn"> <%= submit_tag "Search", class: 'btn btn-default' %> </span> <% end %>
This is the products.rb model class Product < ActiveRecord::Base mount_uploader :image, ImageUploader validates_presence_of :name, :price, :stock_quantity validates_numericality_of :price, :stock_quantity belongs_to :designer belongs_to :category belongs_to :page def self.search(query) where("name LIKE ? OR description LIKE ?", "%#{query}%", "%#{query}%") end end
This is the products_controller.rb class ProductsController < ApplicationController before_action :set_product, only: [:show, :edit, :update, :destroy, :search] before_filter :initialize_cart before_action :authenticate_admin!, only: [ :new, :edit, :update, :create, :destroy ] # GET /products # GET /products.json def index @products = Product.all end def search @products = Product.search(params[:query]).order("created_at DESC") @categories = Category.joins(:products).where(:products => {:id => @products.map{|x| x.id }}).distinct end # GET /products/1 # GET /products/1.json def show end # GET /products/new def new @product = Product.new end # GET /products/1/edit def edit end # POST /products # POST /products.json def create @product = Product.new(product_params) respond_to do |format| if @product.save format.html { redirect_to @product, notice: 'Product was successfully created.' } format.json { render :show, status: :created, location: @product } else format.html { render :new } format.json { render json: @product.errors, status: :unprocessable_entity } end end end # PATCH/PUT /products/1 # PATCH/PUT /products/1.json def update respond_to do |format| if @product.update(product_params) format.html { redirect_to @product, notice: 'Product was successfully updated.' } format.json { render :show, status: :ok, location: @product } else format.html { render :edit } format.json { render json: @product.errors, status: :unprocessable_entity } end end end # DELETE /products/1 # DELETE /products/1.json def destroy @product.destroy respond_to do |format| format.html { redirect_to products_url, notice: 'Product was successfully destroyed.' } format.json { head :no_content } end end private # Use callbacks to share common setup or constraints between actions. def set_product @product = Product.find(params[:id]) end # Never trust parameters from the scary internet, only allow the white list through. def product_params params.require(:product).permit(:name, :description, :price, :image, :category_id, :stock_quantity, :designer_id, :query) end end
this is views/products/search.html.erb <table class="table table-hover"> <thead> <tr> <th>Name</th> <th>Description</th> <th>Designer</th> <th>Price</th> <th>Stock</th> <th>Image</th> </tr> </thead> <tbody> <% @products.each do |product| %> <tr> <td><%= link_to product.name, product %></td> <td><%= product.description %></td> <td><%= product.designer.designer_name %></td> <td><%= number_to_currency product.price %></td> <td><%= product.stock_quantity %></td> <td><%= image_tag product.image.thumb %></td> <% end %> </tr> </tbody>
and in routes.rb I have Rails.application.routes.draw do get 'pages/index' get 'pages/about' get 'pages/location' get 'pages/stockists' devise_for :users resources :categories resources :categories resources :designers resources :category_names resources :products resource :cart, only: [:show] do post "add", path: "add/:id", on: :member get :checkout end resources :orders, only: [ :index, :show, :create, :update ] do member do get :new_payment post :pay end end post 'products/search' => 'products#search', as: 'search_products' root 'pages#index' end

| Database_Cleaner with AR-Octopus not cleaning records Posted: 24 Jun 2016 07:42 AM PDT We have a project that is using the AR-Octopus gem using sharded databases. The problem we are running into is that the gem 'database_cleaner' is not cleaning records when using this setup, as we are consistently having leftover records in our test database that cause issues with our test suite. I found this GitHub gist - https://gist.github.com/nowlinuxing/22ea0ab673a5622eb48d Here is my database_cleaner config file # spec/support/database_cleaner.rb require 'database_cleaner' RSpec.configure do |config| config.before(:suite) do DatabaseCleaner.strategy = :transaction DatabaseCleaner.clean_with(:truncation) end ["master", *Octopus.config[Rails.env].keys].each do |shard| DatabaseCleaner[:active_record, model: ActiveRecord::Base.using(shard)] end config.around(:each) do |example| DatabaseCleaner.cleaning do example.run end end end
Has anyone ever encountered this issue? If so, what did you do to resolve the issue? Just looking for some helpful insight. |
| ActiveRecord query using a joins and where. How do I build it? Posted: 24 Jun 2016 07:46 AM PDT I have this query. I am trying to find a house with no address but with a person with an address. A house belongs to an address and a person has many addresses. A house belongs to a person and a person has many houses. The model names are House, Person, and Address. House.joins(:person).where('houses.address.id = ? and persons.address_id = ?', 'nil', 'not nil')
This query above is wrong but probably what I want. How do I construct it? My SQL isn't very good. |

| Looking for a review of my ActiveRecord relations Posted: 24 Jun 2016 07:17 AM PDT I recently just started learning RoR and I am creating a hobby project. So some quick background: Each customer is identified by an account number. Each product sale has an account number attributed with it and the products table contains all the specific product data. My question is - with the format I have now, is this the proper way I should be linking these tables? One of the issues I am having is filtering a group of sales based on product major. So say I have a customer and I only want to view product sales where the major is "commercial", how do I go about filtering this data? See the scope I created - but I am not sure how to use it. class Product < ActiveRecord::Base has_many :product_sales, :primary_key => :prodnum, :foreign_key => :prodnum has_many :customers, through: :sales scope :commercial_products, -> { where(major: 'Commercial') } end class ProductSale < ActiveRecord::Base belongs_to :customer, :foreign_key => :account belongs_to :product, :foreign_key => :prodnum, :primary_key => :prodnum end class Customer < ActiveRecord::Base has_many :product_sales, :primary_key => :account, :foreign_key => :account has_many :products, through: :product_sales end
and my schema create_table "customers", force: :cascade do |t| t.integer "account" t.string "name" t.datetime "created_at", null: false t.datetime "updated_at", null: false end create_table "product_sales", force: :cascade do |t| t.integer "account" t.string "month" t.string "prodnum" t.integer "sales" t.integer "qtyshipped" t.datetime "created_at", null: false t.datetime "updated_at", null: false end create_table "products", force: :cascade do |t| t.string "pcatcode" t.string "pcatname" t.string "major" t.string "prodline" t.string "brand" t.string "tier" t.string "prodnum" t.string "proddesc" t.datetime "created_at", null: false t.datetime "updated_at", null: false end

| Bring "assets" bundler group back in Rails 4 Posted: 24 Jun 2016 06:45 AM PDT Not sure why it was removed, but how would I go about adding the "assets" bundler group back into my Gemfile, and having it only be included for asset precomplication on deploy (as well as development etc.)? Basically, to recreate the functionality that was already present in Rails 3. My rationale is to reduce runtime memory usage, since the gems I would put into that group are only really needed during asset precompilation. Also, is there any inherent reason why this would be a bad idea? I deploy to Heroku, in case that makes any difference. |

| How do I modify the creation of an associated object when done via accepts_nested_attributes_for for another object? Posted: 24 Jun 2016 07:38 AM PDT I have a Job model, that belongs_to :company. Both models belong_to :user (i.e. the current_user). Job accepts_nested_attributes_for :company.
I have my company attributes on the jobs/_form.html.erb. But, what is happening is that when the company object is being created, it isn't setting an attribute I want it to (company.user_id). I am not quite sure how to force it to do that. This is what the log for this part of the operation looks like: Company Exists (1.4ms) SELECT 1 AS one FROM "companies" WHERE ("companies"."id" IS NOT NULL) AND "companies"."slug" = $1 LIMIT $2 [["slug", "phish-me"], ["LIMIT", 1]] SQL (2.7ms) INSERT INTO "companies" ("name", "logo", "description", "city", "state", "country", "email", "created_at", "updated_at", "slug") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10) RETURNING "id" [["name", "Acme Corp"], ["logo", "#<ActionDispatch::Http::UploadedFile:0x007f>"], ["description", "Some random description."], ["city", "Leesburg"], ["state", "Virginia"], ["country", "US"], ["email", "random@email.com"], ["created_at", 2016-06-24 09:50:49 UTC], ["updated_at", 2016-06-24 09:50:49 UTC], ["slug", "acme-corp"]]
I even tried including a hidden field for the user_id in the company portion of that form and it didn't work. I added a binding.pry to my Company#Create action and it didn't work - so it seems that's not being called. I am not quite sure how to modify that Create event and ensure that company.user = job.user How do I do that? |
| Storing passwords in a database Posted: 24 Jun 2016 06:38 AM PDT There are many questions on SO about how to store passwords in a database and i'm aware passwords should under no circumstances be stored in plain text. However, my application requires authentication against various third parties, such as SMB or REST APIs that don't provide OAUTH. In short: i need to store passwords. To avoid storing passwords in clear text, my idea is to store a secret key in an environment variable and use that for encrypting / decrypting the passwords. Is that a good approach for the problem or are there any better options? |

| How to restrict current_user from adding more than 3 order_items to a order per time period? Posted: 24 Jun 2016 06:35 AM PDT I'm building a store in Rails that has a specific sales model. I need to allow a user to add only 3 items to his order per 30 days. The 30 days counter should start upon adding the first order_item. Once 30 days expires, user would be able to add 3 orders. If 30 days didn't pass and for an example, user adds two order_items he would still be allowed to add one more order_item within 30 days. So as well if user tries to add more then 3 items to show an error message and disregard saving of the order_items to current_user's order. I have products, orders, order_items, users. I guess that I should add something to user model but I'm not sure what. order_items_controller.rb def create @order = current_order @order_item = @order.order_items.new(order_item_params) @order.user_id = current_user.id @order.save session[:order_id] = @order.id respond_to do |format| format.js { flash[:notice] = "ORDER HAS BEEN CREATED." } end end private def order_item_params params.require(:order_item).permit(:quantity, :product_id, :user_id) end end

| Rails + AngularJS + ActionCabel + Websocket Posted: 24 Jun 2016 07:49 AM PDT I am doing rails + angularjs application with real time chat, based on websocket within action cable. I have done all required things about sending and receiving messages through channel connections. $scope.moreMessages = function() { AccountsMessages.query({ conversation_id: $scope.conversationId, page: $scope.page }, function(response) { $scope.page += 1; $scope.messages = response.messages.concat($scope.messages); } ) } function init() { $scope.moreMessages(); }; init(); var cable = $cable('/cable'); var channel = cable.subscribe({ channel: 'MessagesChannel', conversation: $scope.conversationId }, { received: function(newMessage) { if (newMessage) { $scope.messages.push(newMessage); $scope.$apply(); } } }); $scope.save = function() { channel.send({ conversation_id: $scope.conversationId, body: $scope.message.body, state: 'unread' }); $scope.message = {}; };
But right now I am doing read/unread for messages. It is like, one user sends a message to another user. By default, it appears like it is with 'unread' state. But if another user, receiver, views this message, it becomes 'read' or 'viewed'. The problem is, how can I update it like so, that sender dynamically could see mark 'read' on the message state right after that. It is done on server side, and messages are updated while index(query) action is requested by receiver. But how can I do it for sender's vision? Thanks. |

Any help would be greatly appreciated or help with setting up my config/ldap.yml to match my test class. Here is my config/ldap.yml #Environment development: host: myldap.mydomain.com port: 389 attribute: sAMAccountname base: dc=mydomain, dc=com admin_user: cn=admin,dc=mydomain,dc=com admin_password: password #ssl: false
Here is my devise.rb Devise.setup do |config| # ==> LDAP Configuration config.ldap_logger = true # config.ldap_create_user = false # config.ldap_update_password = true config.ldap_config = "#{Rails.root}/config/ldap.yml" # config.ldap_check_group_membership = false # config.ldap_check_group_membership_without_admin = false config.ldap_check_attributes = true #config.ldap_use_admin_to_bind = true # config.ldap_ad_group_check = false
this is what I get back when using ldap with devise.

Here is my test class that works to authenticate with ldap on my microsoft AD require 'net/ldap' # gem install ruby-net-ldap module Test class PutAd SERVER = 'myldap.mydomain.com' PORT = 389 BASE = 'DC=mydomain,DC=com' DOMAIN = 'mydomain.com' ATTR_SV = { :login => :samaccountname, :first_name => :givenname, :last_name => :sn, :email => :mail } def self.authenticate(login, pass) return nil if login.empty? or pass.empty? conn = Net::LDAP.new :host => SERVER, :port => PORT, :base => BASE, :auth => { :username => "#{login}@#{DOMAIN}", :password => pass, :method => :simple } if conn.bind and user = conn.search(:filter => "sAMAccountName=#{login}").first return self.new(user) else return nil end rescue Net::LDAP::LdapError => e return nil end end end
^This will return my account information if it matches if not it will return nil. |
| Efficient inline editing in Rails Posted: 24 Jun 2016 05:08 AM PDT I want to integrate functionality like LinkedIn where, when you're logged in, you can hover over your info on profile page and it will enable you to click on a certain field and you can edit it. And, if it passes validation, that record is edited in the database. I've seen some jQuery plugins, but I want to stay away of jQuery because of the performance. Are there any Rails solutions or gems that will do this? |
| Add a new object of a Model without going to /model/new in Rails Posted: 24 Jun 2016 05:33 AM PDT Let's say I have my Home page and a Post model. If I want to add a new Post, I go to /posts/new and create a new object of a Post class. That is a standard way. Can I include, for example, in my Home Page, a + button that will open a small window asking me to type title and content and have the same effect as the standard way ? |

| Get day numbers of a week number Posted: 24 Jun 2016 04:40 AM PDT In my application I store activities with a day_number ranging from 1 to 31 and a number of hours. Any activity belongs to a timesheet which contains a month and year. Now I want to have an overview with all the weeks in a year and with the total number of activity hours in that week. I determine the weeks of a month with: first_week = Date.new(timesheet.year,timesheet.month,1).strftime("%U").to_i last_week = Date.new(timesheet.year,timesheet.month,1).end_of_month.strftime("%U").to_i weeknrs = (first_week..last_week).to_a weeknrs.each do |weeknr| # Do something end
How can I determine the day numbers belonging to a specific week? |

| Rails Presenter Pattern - Yield Duplicates HTML Code Posted: 24 Jun 2016 04:03 AM PDT I'm doing a bit of view logic refactoring, following the presenter pattern Ryan Bates brilliantly tutors in his #287 Presenters from Scratch Railscast- which can be seen here: http://railscasts.com/episodes/287-presenters-from-scratch I have a scenario where a view file HTML logic is wrapped in a few ugly if statements limiting access to the page, based on certain attributes of the model. For Example: <% if @user.my_friend? %> <% if @user.not_apart_of_group? %> <div> Sorry, you're not apart of your friends group! </div> <% else %> <% if @user.group_admin? %> /* html code to edit group, with lots of horrid logic */ <% else %> <div> Sorry, you're not an admin of your friends group! </div> <% end %> <% end %> <% else %> <% if @user.not_apart_of_group? %> <div> Sorry, you're not apart of this public group! </div> <% else %> <% if @user.group_admin? %> /* html code to edit group, with lots of horrid logic */ <% else %> <div> Sorry, you're not an admin of this public group! </div> <% end %> <% end %> <% end %>
My above example mimics a scenario where the view page is used to render a group admin page for both friend groups and public group, but the one served depends on some logic in the controller. As you can see, it's a horrible mess of nested if statements in the view file, so I began to move it a presenter ruby class that contains methods that does the job of the if statements. For example, in the view file, I call the method as a block and pass the html code that I want to render, if the @user object meets all the requirements of the page: <% present @user do |user| %> <%= user.render_group_admin do %> /* html code */ <% end %> <% end %>
In my presenter class, I have the method render_group_admin which yields the html code if the @user object meets of the criteria, or returns the content_tag with one of the above simple splash screens- this again depends on what criteria the object doesn't meet: class User::UserPresenter < BasePresenter presents :user def render_group_admin if user.is_friend h.content_tag :div, class:"blah blah blah" do "Sorry, you're not apart of your friends group!" end elsif ... #various condition checks else yield #meets all conditions, so we'll yield the html end end end
This worked great and allowed me to completely remove the nested if statements from the view file and put them in a Ruby Class that does the job for me and allows me to write RSpec test that test the logic directly (and avoid that horrible capybara for front end testing). Well, apart from one problem.... When I ran the code for the first time, I found that my presenter method was rendering (or yielding) the html code passed to it, twice. I did a bit a tinkering and found that adding return "" under the yield, like so: class User::UserPresenter < BasePresenter presents :user def render_group_admin if user.is_friend h.content_tag :div, class:"blah blah blah" do "Sorry, you're not apart of your friends group!" end elsif ... #various condition checks else yield #meets all conditions, so we'll yield the html return "" end end end
This sorted the issue, well, I guess renders my html code + the blank string- but aesthetically, achieved what I wanted. Albiet, in a hacky looking way. My questions really are: why does yield render my html code twice, when called in a helper-like method from the view file? Is there a way to stop this duplication behavior in a better way than simply putting the line return "" under it? Thanks in advance guys and gals, |
| Anything wrong with this plan for my model associations Posted: 24 Jun 2016 05:28 AM PDT I'm creating an app that allows users to take multiple choice quizzes that I create. There's a Quiz model, a Question Model, and an Answer model. The Quiz model has_many questions which has_many answers (and they all belongs_to the model intuitively above them). answers will have a correct_answer boolean attribute that indicates ONE of the answers to be the correct answer. (and they all belongs_to the model intuitively above them). This is to create the quiz. To provide support for user input once the quiz has already been created, I want to define two other models: SubmittedAnswer and SubmittedSurvey. SubmittedSurvey belongs_to User, and also belongs_to Survey (both of which has_many submittedsurveys). SubmittedSurvey also has_many submittedanswers. So when you visit the page that displays the quiz, it allows user input which submits data that sets submittedanswers. Then, since submittedsurvey belongs_to survey, I can compare submittedanswers to the answers themselves and grade the quiz. Is this reasonable or should I do it some other way? |
