| How to send canvas image to database on form submit in Rails Posted: 09 Aug 2016 07:31 AM PDT I'm creating an app in Rails where users are able to draw on an html5 canvas with JavaScript. With JavaScript, I've been able to convert the canvas to an image so the user can easily right click the canvas and save the image: var img = new Image; img.onload = function(){ ctx.drawImage(img,0,0); }; img.src = window.mapImgUrl;
However, the problem is that the canvas lives on a form. I want the image result to somehow get added to the database so I can show previous drawings on other views of the app. I set up CarrierWave and AWS for image uploads, but I can't figure out a way to reconfigure the settings to treat the canvas images as uploads on submitting the form. Is this something that will have to involve AJAX or base64? Or is there some way to make use of CarrierWave for this? |
| rake db:migrate rake aborted! StandardError: An error has occurred Posted: 09 Aug 2016 07:06 AM PDT Would be very grateful if someone could help at least to understand where the issue could be coming from. I'm having problems with migration with the project I'm working on. I even started a brand new one but the issue is still assuring the same. Error messages appearing on attempts to do rake db:migrate (have tried both starting new project with the default database- sqlite3 and the optional- postgresql ), however, after generating a model (tried both with rails g scaffold Schedule name:name dep_date:datetime and just model - rails g model Schedule name:name dep_date:datetime ) migration stays down. the migration itself is: class CreateSchedules < ActiveRecord::Migration[5.0] def change create_table :schedules do |t| t.name :name t.datetime :dep_date t.timestamps end end end
command: rake db:migrate:status gives the following: database: travel_t_challenge_development Status Migration ID Migration Name down 20160809121048 Create schedules

| Paperclip::Error (There was an error processing the thumbnail Posted: 09 Aug 2016 06:58 AM PDT Paperclip::Error in RegistrationsController#update There was an error processing the thumbnail. I'm Running Rails 4.2.6 and paperclip", "~> 5.0.0" My application controller file is: class NewsController < ApplicationController def create @news = News.new(news_params) respond_to do |format| if @news.save format.html { redirect_to news_url, notice: 'News post was successfully created.' } format.json { render :show, status: :created, location: @news } else format.html { render :new } format.json { render json: @news.errors, status: :unprocessable_entity } end end end private def news_params params.require(:news).permit(:topic, :header, :content, :link, :image) end end
My news model is: class News < ActiveRecord::Base validates :image, presence: true has_attached_file :image, styles: { thumb: "64x64#", small: "100x100#", med: "150x150#", large: "200x200# -adaptive-resize" }, default_url: "/images/:style/missing.png" validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/ end
And my database migration for paperclip is: class AddAttachmentImageToNews < ActiveRecord::Migration def self.up change_table :news do |t| t.attachment :image end end def self.down remove_attachment :news, :image end end
When I rake db:migrate this and then try to use it I get the Paperclip::Error in NewsController#create There was an error processing the thumbnail for dfc9ea4994791a9884f662cfa4333da420160809-29993-12b0k3n. I previously had an attribute of the news class called image, not sure if that messes anything up? It seems like it's a database problem, since if I do a rake db:setup it works fine. But, I don't want to wipe my database, so that's not an option, since db:setup runs a db:schema:load this will delete data on the server. Any help or suggestions would be appreciated. Thanks. |
| How can I make a link to the result of a model method in my views? Posted: 09 Aug 2016 06:47 AM PDT I have this method in my model: ## Finds invoice with next upcoming due date. ## def self.next_due where("due_date >= ? AND status = ?", Time.now, 'Open').order("due_date ASC").first ? where("due_date >= ?", Time.now).order("due_date ASC").first.due_date : '' end
This returns the due_date of the next invoice due. I am trying to make a link_to to the actual invoice but so far have not been able to get it to work. I feel like such an idiot because I can't make a simple link work when I've had no problems with links that I couldn't quickly sort out on my own up till now. Is it possible to store the invoice returned by this query as a variable that I can call from the view and link to? If not, then how would I go about making the link? Thanks. |

| How to display posts using Modals Posted: 09 Aug 2016 06:13 AM PDT I'm new to RoR and I've encountered a problem recently as I am trying to display different posts in different modals. To contextualize I have a Home page on which is displayed every post. Every post contains an author, a content, a like button and a comment button. I want the comment button to open a modal containing again the author's name, the content and an area to comment the post. The problem is that every modal that I click on contains the same author and the same content even if the comment button I clicked on is from a different post. To be precise the content displayed in the Modal is from the most recently posted post. Tell me if you need something in particular and I will be happy to edit this post with the code you ask me. Displaying the posts: <% @posts.each do |post| %> <div class="media"> <a class="media-left" href="#"> <div class='circle-icon'> <span class="glyphicon glyphicon-user" aria-hidden="true"></span> </div> </a> <div class="media-body"> <h2 class="media-heading"><%= post.user.first_name %> <%= post.user.last_name %></h2> <h4><%= post.content %> </h4> <br>Submitted <%= time_ago_in_words (post.created_at) %> ago<br> <%= button_to like_post_path(post), method: :put do %>Like<%= post.get_upvotes.size %> <% end %> <a href="#" data-toggle="modal" data-target="#myModal" class="btn btn-xs btn-primary"><span class="glyphicon glyphicon-comment"></span> Comment</a>
And here is my Modal: <!-- Modal --> <div class="modal fade .local-modal" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel"><%= post.user.first_name %> <%= post.user.last_name %></h4> </div> <div class="modal-body"> <p><%= post.content %> </p> <hr> <fieldset class="form-group"> <label for="exampleTextarea">Write your comment:</label> <textarea class="form-control" id="exampleTextarea" rows="3"> </textarea> </fieldset> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" >Like</button> <button type="button" class="btn btn-primary" data-dismiss="modal">Comment</button> </div> </div> </div> </div>

| Rspec Mocking A Class Instance Posted: 09 Aug 2016 05:55 AM PDT If in my Rspec test I have... foo = mock_model(Foo, id: 1)
& my code runs... Foo.where(id: 1)
My code will always fail as the mock_model foo never gets to belong to the Foo collection... e.g. Foo.count # => 0 If I run foo.instance_of?(Foo) i'll get true so the behaviours right... What am I missing? I'd like to rely on true mocks & not have to rely on FactoryGirl or instantiate an object of Foo itself... |

| How to save city, state, zip and country based on address using geocoder gem Posted: 09 Aug 2016 05:43 AM PDT I have user model in which user search address and what I need to do is to update fields like city, state, zip and country based on that address. The problem I am facing is, I cant able to get this information and pass it to update params. See code: geocoded_by :address do |obj,results| if geo = results.first obj.city = geo.city obj.lat = geo.latitude obj.lng = geo.longitude obj.zip = geo.postal_code obj.state = geo.state obj.country = geo.country_code end end after_validation :address
If I puts results and geo it returns nil only. I wants to have Longitude, Latitude, city, state, zip, and country based on Address search and then pass all of them to update method so they will automatically get updates in the system. And for doing all of this I am using Geo Coder GEM |

| Ruby on rails - Datepicker with I18n - Jquery Posted: 09 Aug 2016 05:16 AM PDT I am changing my current datepicker to this, daterangepicker. I have this working correctly but I am having trouble with the translations. I think it's a jquery problem as if I put in a comma after the last translation, the calendar shows in Spanish regardless or locale, and if I leave out this comma then the calendar shows in English, regardless of locale.
datepicker jquery: $(function() { return $('#q_daterange').daterangepicker({ "autoApply": true, "locale": { "format": "MM/DD/YYYY", "daysOfWeek": ['<%= I18n.t('datepicker.sun') %>', '<%= I18n.t('datepicker.mon') %>', '<%= I18n.t('datepicker.tue') %>', '<%= I18n.t('datepicker.wed') %>', '<%= I18n.t('datepicker.thu') %>', '<%= I18n.t('datepicker.fri') %>', '<%= I18n.t('datepicker.sat') %>' ], "monthNames": [ '<%= I18n.t('datepicker.january') %>', '<%= I18n.t('datepicker.february') %>', '<%= I18n.t('datepicker.march') %>', '<%= I18n.t('datepicker.april') %>', '<%= I18n.t('datepicker.may') %>', '<%= I18n.t('datepicker.june') %>', '<%= I18n.t('datepicker.july') %>', '<%= I18n.t('datepicker.august') %>', '<%= I18n.t('datepicker.september') %>', '<%= I18n.t('datepicker.october') %>', '<%= I18n.t('datepicker.november') %>', '<%= I18n.t('datepicker.december') %>' ], "firstDay": 1 }, "showCustomRangeLabel": false, "minDate": new Date(), "startDate": new Date(), "endDate": new Date(+new Date + 12096e5), "opens": "left", }, function(start, end, label) { $('#q_date_gteq').val(start.format("YYYY-MM-DD")); return $('#q_date_lteq').val(end.format("YYYY-MM-DD")); }).on('apply.daterangepicker', function() { return $('#gig_search').submit(); }); });
Note the line '<%= I18n.t('datepicker.december') %>' has no comma after it. Everything currently shows in English. Adding a comma here makes everything show in Spanish. I cannot spot my error, any help would be appreciated!! |

| Ruby on Rails Session Variable not Showing on Front End on First Render Posted: 09 Aug 2016 04:19 AM PDT I'm having a strange issue where the last value in a session array is not displaying on the front end when a partial is rendered for the first time. I'm using the add_to_box method to add a set of values to a session variable called 'session[:box]'. I then want to update the partial on the front end with the new list of values. Here's the code... (sanitised slightly) Controller: def add_to_box(values_hash) session[:box] ||= [] if params_valid?(values_hash) session[:box].push(values_hash) respond_to do |format| format.js end end end
add_to_box.js.erb: $("#box").html("<%= escape_javascript(render partial: 'box') %>");
Partial _box.html.erb: <ul> <% session[:box].each do |m| %> <li> <%= "#{m['bottom_id']}, #{m['filling_id']}, #{m['top_id']}" %> </li> <% end %> </ul>
Console output: Started POST "/things/add_to_box" for ::1 at 2016-08-09 11:59:23 +0100 Processing by ThingController#add_to_box as JS Rendered things/_box.html.erb (0.9ms) Rendered things/add_to_box.js.erb (2.8ms) Completed 200 OK in 17ms (Views: 8.2ms | ActiveRecord: 0.7ms)
The first time the method is called (values 1,1,1), the front end displays as: ∙ , , The second time the method is called (values 2,2,2), the front end displays as: ∙ 1, 1, 1 ∙ , , The third time the method is called (values 3,3,3), the front end displays as: ∙ 1, 1, 1 ∙ 2, 2, 2 ∙ , , You get the picture... Essentially the latest value is never rendered. BUT if I refresh the page, it shows correctly with all values: ∙ 1, 1, 1 ∙ 2, 2, 2 ∙ 3, 3, 3 I thought at first it could be because the values aren't saved in time and the render is happening first, but then how does it know there is a new set of values before they have been set?!

| Building an RSVP system in Rails with has_many, through Posted: 09 Aug 2016 04:25 AM PDT I have an Events app in Rails 5 and I'm trying to build an RSVP system. The functionality that I'm trying to build is that a user can go to the events show page and click an 'rsvp' button. This user will then show up in the events show page under 'users attending this event'. Additionally, the event will also show up on the user's show page - 'this user is attending the following events'. I'm pretty new to Rails and I'm not really sure how to handle the rsvp button functionality. This is my code so far: user.rb class User < ApplicationRecord ... has_many :attendances has_many :events, through: :attendances ... end
event.rb class Event < ApplicationRecord has_many :attendances has_many :users, through: :attendances end
attendance.rb class Attendance < ApplicationRecord belongs_to :user belongs_to :event end
routes.rb Rails.application.routes.draw do root 'events#index' resources :events do resources :users end resources :users end
And this is the form on the events show page where I'm trying to add a user to the event show.html.erb - events <%= form_for([@event, @event.users.build] do |f| %> <%= f.hidden_field :user_id, value: current_user.id %> <%= f.submit "RSVP", class: "btn btn-default" %> <% end %>
Please let me know if you need any extra code posting. |
| looping over records with condition Posted: 09 Aug 2016 04:14 AM PDT I have a Customer model that has the attribute private. This attribute is only visible for a total of 3 users in the database. If this method (check_box) gets checked by one of those 3 users the Customer is only visible by them. I'm currently looping over all of the Customers like this: <% @customers.where(:private => false).each do |single_customer| %>
My question is how can I accomplish when one of the 3 users is signed in that :private => false gets changed to @customers.each do |single_customer| because then I don't want to filter the private attribute anymore. |

| Optimization Ruby on Rails (count) Posted: 09 Aug 2016 04:46 AM PDT How is it possible to optimize this code? ( (Many messages) def messages_count total = 0 users.each do |u| total += u.messages.size end total end
Thanks you |
