| Add price label in chartkick.js Posted: 27 Nov 2016 07:35 AM PST I'm using chartkick to generate a bar chart, with this data that generated via ajax in ruby on rails, @data = [ { name: "Fruits", data: [["2010", 10], ["2020", 16], ["2030", 28]] }, { name: "Meats", data: [["2010", 24], ["2020", 22], ["2030", 19]] }, { name: "Vegetables", data: [["2010", 20], ["2020", 23], ["2030", 29]] } ]
All I want to ask is how to add like $ label, so in example, the bar label would show 20$ in 2010 for vegetables? Thanks before. |

| Add Objects on Rails Server Posted: 27 Nov 2016 06:56 AM PST meanwhile I'm pretty desperate since I can't continue working on my Website. I created a Ruby on Rails server and added a products controller via scaffolding. When I am on my local server, I can add a new product (new object of the product category) with the already given Rails structure. But I want to add the objects/products in my text documents, but where exactly is this possible? I know I can add a product like so: bike1 = Bike.create ( :name => "Nice Bike" ) But where exactly do I have to add it that it is displayed on the show page of the Product controller? And is it possible to see my created products in my database folder? Thank You! |

| How to update if statement in views through AJAX in Rails app Posted: 27 Nov 2016 03:59 AM PST In my app I have votable posts where you vote through AJAX which works fine but I want to update status of the post (whether it is agreed milestone) upon voting through AJAX as well. Status of the post is in views: <div id="milestone-<%= post.id %>"> <% if post.agreed? %> Agreed Milestone <% elsif post.milestone? %> Proposed Milestone <% end %> </div>
posts_controller.rb def upvote @post = Post.find(params[:post_id]) respond_to do |format| format.html { redirect_to @post } format.js @post.upvote_by current_user end if @post.votes_for.up.size == count_users @post.toggle! :agreed end end
upvote.js.erb $('#voting-<%= @post.id %>').hide(); $('#agreed-<%= @post.id %>').html("<%= j render(partial: 'posts/agreed', locals: {post: @post}) %>");
Agreed partial is list of voters. So when post reaches certain number of votes it changes its boolean agreed to true. I want to then update status in views. I tried rendering milestone element as partial and several other approaches but the if statement is never executed and status does not update. |
| Does queries per second in MySql really matter? Posted: 27 Nov 2016 02:10 AM PST For example, if you were to have a webpage that writes 10 times (5ms each query so relatively inexpensive) to a MySQL database every time you visited the page. Would it be the same thing as a page load that writes only one query that is 50ms instead? What I'm basically asking is does queries per second really matter? Will it bottleneck my database faster? If I had a pretty large database, is there any differences of writing 10000 inexpensive queries per second versus 1000 more expensive ones? |

| How to address shortcomings of associated model from Rails tutorial Posted: 27 Nov 2016 03:07 AM PST I followed the getting started tutorial for Rails which was fine for the most part, but lacked some detail when it came to the associated model (comments): - There was no validation - it's easy enough to add that, but then I wasn't sure how to display the error messages from failed validation.
- Using
@article.comments.build so you can display the comment form effectively "created" another comment in that session, so if you iterate through all comments, there'd be an extra blank one because of that. It's just a coincidence that the guide listed the comments before that line of code was executed, and thus didn't encounter the problem. Whilst I tried something for 1. (which will be detailed below), I've no idea how to go about solving 2. - it probably belongs in its own question, but I'm not even sure how to name it. Attempt at validation/error display I tried to basically apply the same strategy for displaying error messages with the articles, again for the comments. I knew there'd be some extra complexity, but I tried to navigate it logically. This is what I changed: app/models/comments.rb class Comment < ApplicationRecord belongs_to :post validates :commenter, presence: true validates :body, presence: true end
app/controllers/comments_controller.rb class CommentsController < ApplicationController def create @article = Post.find(params[:article_id]) @comment = @article.comments.new(comment_params) if @comment.save redirect_to article_path(@article) else render 'articles/show' end end def destroy ...
app/views/comments/_form.html.erb <%= form_for([@article, @article.comments.build]) do |f| %> <% if self.instance_variable_defined?('@comment') and @comment.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@comment.errors.count, 'error') %> occurred:</h2> <ul> <% @comment.errors.full_messages.each do |msg| %> <li><%= msg %></li> <% end %> </ul> </div> <% end %> <p> <%= f.label :commenter, 'Your Name' %> ...
Whilst this successfully displayed the error messages, the following problems occurred: - Because it uses render instead of redirect, the user ends up on a URL that normally can't serve
GET requests (i.e. /posts/1/comments) - this is strange, because if the page loads again it'll 404. I can't use redirect though, because then the attempted comment creation (with the error messages) will be lost. - Presumably because
@article.comments.new has been executed prior to rendering, the same problem as that which was described in 2. above (regarding @article.comments.build) occurs: a blank comment is displayed. So that's where I'm stuck. These are pretty basic problems - the system wouldn't be whole without them, and yet I'm lost for what the proper solution would be. How can I display these errors whilst avoiding the above problems? |

| Why does order of migrations matter in Heroku Postgres but not local Postgres database? Posted: 26 Nov 2016 09:42 PM PST I was having a hell of a time earlier trying to figure out why Heroku couldn't run my migrations. It kept complaining that a reference did not exist. For my first migration, I referenced a table that hadn't been created yet using a foreign key. In order to solve this problem, I had to arbitrarily modify the timestamps of the migration files so that no table would be created before a table it depends on (references). Amazingly, this solved the problem with running the migrations on Heroku and they eventually ran without error. Also, the migrations would run perfectly on my development machine, even with the tables that have dependencies being created before the referenced tables exist. Why did it work on my local database and not on the Heroku database? Is there something I can do next time this happens? It seems really ridiculous to have to always create migrations in order of their dependency in order to please Heroku. I must be missing something, no?

I want to encrypt password without adding or modifying my existing database. Can it be possible using this gem ? Thanks, Hare |
| How to implement an index like action, that limits the fields displayed depending on user parameters? Posted: 27 Nov 2016 05:53 AM PST I want to implement an action that functions just like index, but with the catch being that if the in the request URL, it specifies that it wants field 1 and field 2, it should only render field 1 and field 2. Now this would be trivial if it's only done for a JSON response, but how do I implement this for HTML views too ? The only way I can think of is having a separate view for each combination of fields, but that would be insane. Surely there must be a way that I am completely oblivious of to implement this. |
| What does resource mean in Devise? Posted: 26 Nov 2016 08:56 PM PST I want to change what happenes in devise when a user logs in.. When I look at the source code the word resource is everywhere, but I can't understand what it is a stand in for. Does it only pertain to devise and warden? def after_sign_in_path_for(resource) stored_location_for(resource) || if resource.is_a?(User) && resource.can_publish? publisher_url else super end end

| Statement Invalid in DoorKeeper Error Posted: 26 Nov 2016 08:57 PM PST I am getting a peculiar error when using Doorkeeper in my rails app. Here is what my doorkeeper.rb file looks like: Doorkeeper.configure do # Change the ORM that doorkeeper will use (needs plugins) orm :active_record # This block will be called to check whether the resource owner is authenticated or not. resource_owner_authenticator do |routes| # Put your resource owner authentication logic here. # Example implementation: User.find_by_id(session[:user_id]) || redirect_to(routes.login_url) end end
When I go to the route localhost:3000/oauth/authorize with my logged in user it throws this error: ActiveRecord::StatementInvalid in Doorkeeper::AuthorizationsController#new Could not find table oauth_application def table_structure(table_name) structure = exec_query("PRAGMA table_info(#{quote_table_name(table_name)})", 'SCHEMA') raise(ActiveRecord::StatementInvalid, "Could not find table '#{table_name}'") if structure.empty? table_structure_with_collation(table_name, structure) end
Could anyone tell me why this error might be occuring?Thanks in advanced for the help. |
| Clickable text for radio button on Rails Posted: 26 Nov 2016 08:18 PM PST <%=form_for @link do |f| %> <%= f.collection_radio_buttons :title, [['💩'] ,['😊'],['😡'],['😏'], ['🙃']], :first, :last%> <%= f.submit 'Save'%>
I'm trying to make the the emojis of my radio buttons clickable (instead of clicking the circle button I want to click the actual emoji). Then, I want to get rid of the little circle buttons so all that can be seen is the emojis. Finally, I want there to be some sort of visual signal when one of the emojis is chosen, such as a highlight, since the actual radio button will be gone. I'm using the simple_form gem. I've searched for days but can't figure out how to do this. Thank you so much for your help! |
| Using Angular, Trying to Save An Array to the Rails Backend Posted: 27 Nov 2016 07:34 AM PST I tried several methods I found online but none worked and they weren't specifically targeting the problems I'm having. Basically I have a recipes Rails app, and using Angular, I have to:
(1) Allow the user to add one or more ingredients and directions in the form, like this: http://jsfiddle.net/V4BqE/
(2) Save the ingredients and directions as an array data type in the Rails database (I'm using postgresql), sort of like this but without using $scope: How to create an Array with AngularJS's ng-model Schema: create_table "recipes", force: :cascade do |t| t.string "title" t.integer "difficulty" t.integer "time" t.integer "servings" t.string "description" t.string "ingredients", array: true t.string "directions", array: true t.integer "category_id" t.integer "author_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false end
Controller: (function() { 'use strict'; function NewRecipeController ($location, RecipeService, CategoryService) { var vm = this; CategoryService.getCategories() .then(function(response) { vm.categories = response.data; }); vm.addRecipe = function() { var data = { title: this.title, difficulty: this.difficulty, time: this.time, servings: this.servings, description: this.description, // Im stuck trying to figure out the following 2 lines ingredients: this.ingredients, directions: this.directions, category_id: this.category.id }; RecipeService.createRecipe(data); $location.path('profile'); }; } angular .module('app') .controller('NewRecipeController', NewRecipeController) }());
Form (just the ingredients and directions section are relevant): <form name="newRecipe" novalidate ng-submit="vm.addRecipe()"> <!-- title --> <div class="form-group"> <label for="title">Recipe Name</label> <input class="form-control" type="text" name="title" ng-model="vm.title" required> </div> <!-- category --> <div class="form-group"> <label for="category">Category</label> <select class="form-control" name="category" ng-model="vm.category" ng-options="category.name for category in vm.categories" required></select> </div> <!-- description --> <div class="form-group"> <label for="description">Description</label> <input class="form-control" type="text" name="description" ng-model="vm.description" required> </div> <!-- difficulty --> <div class="form-group"> <label for="difficulty">Difficulty</label> <input class="form-control" type="number" name="difficulty" ng-model="vm.difficulty" min="1" max="5" required> <small id="emailHelp" class="form-text text-muted">Enter a number between 1 and 5.</small> </div> <!-- time --> <div class="form-group"> <label for="time">Time to Make (Minutes)</label> <input class="form-control" type="number" name="time" ng-model="vm.time" min="5" step="5" required> <small id="emailHelp" class="form-text text-muted">Enter a number that is an increment of 5 minutes.</small> </div> <!-- servings --> <div class="form-group"> <label for="servings">Servings</label> <input class="form-control" type="number" name="servings" ng-model="vm.servings" required> </div> <!-- ingredients - this is where I'm stuck --> <!-- I want to be able to let the user add more input fields if they want and do the same for directions --> <div class="form-group" ng-repeat="ingredient in vm.ingredients"> <label for="ingredients">Ingredients</label> <input class="form-control" type="text" name="ingredients" ng-model="vm.ingredients[$index]" required> </div> <div ng-show="newRecipe.$valid"> <input class="btn btn-primary" type="submit" value="Create Recipe"> </div> </form>
I understand that I have to save the array as a string. I tried directly saving ingredients: '["ingredient1", "ingredient2"]' and ingredients: '["ingredient1, ingredient2"]', but both just saved as ingredients: ["ingredient1"]. I've also tried JSON.stringify(ingredients). I am using a serializer: class RecipeSerializer < ActiveModel::Serializer attributes :id, :title, :difficulty, :time, :servings, :description, :ingredients, :directions belongs_to :category belongs_to :author, class_name: 'User' # has_many :favorites has_many :favorited_users, through: :favorites, source: :user end
Recipe Rails controller #create: def create @recipe = Recipe.new(recipe_params) @recipe.author = current_user @recipe.save end
