| RAILS Issue with User Cart Posted: 13 Jun 2016 07:42 AM PDT I've got a rails cart for a customer which works BUT only on the second attempt of trying to 'add-to-cart'. So everytime i click 'add to cart', the cart is empty the first time. But on second attempt, the item is added to cart. What am i doing wrong??

| Pundit::NotDefinedError: unable to find policy when moving from Pundit 0.3 to 1.0 Posted: 13 Jun 2016 07:40 AM PDT When I am running rspec wit pundit version 1.0 on one of my project spec classes I get multiple errors which I haven't seen before. However, when I'm switching to the previous version of pundit (0.3) everything works correctly. Up to now what I have noticed is that with newer version of pundit @error in create function is not correctly assigned (instead of error class, I get an error message string from the error class). class ErrorsController < ApplicationController before_action :set_execution_environment def authorize! authorize(@error || @errors) end private :authorize! def create @error = Error.new(error_params) authorize! end def error_params params[:error].permit(:message, :submission_id).merge(execution_environment_id: @execution_environment.id) end private :error_params

| How to properly isolate multiple rails applications in development (local machine) Posted: 13 Jun 2016 07:39 AM PDT Given we use a preferred flavour of a ruby version manager (RVM or Rbenv) the ruby gems are isolated per ruby version. Let's say we want to work on multiple applications locally (they are completely separate applications) and we want to use the same ruby version and the same rails version how do we properly isolate them and their gems? Are gemsets the (only) answer here? I mean if I have 5 applications with the same ruby version and I keep adding gems on all 5 fronts it's just a matter of time when one of the applications is ok with the latest stable gem version while one of the apps will still need to roll on an older version of the same gem due to legacy dependency or whatnot. How do you guys avoid this timebomb? What if we want to use the same ruby version on multiple apps but a different Rails version? Rails being 'just a gem' is the answer same as for the above? Thanks. |
| Rails: Retrieving DB records where attribute's parent meets criteria Posted: 13 Jun 2016 07:27 AM PDT I want to retrieve database records where an associated foreign entry's parent meets a certain criterion. I have a Discipline model (for academic discipline). A Discipline can have another Discipline as a parent (e.g. "Social Sciences" would be the parent to "Anthropology"); there are only 2 levels, i.e. a Discipline with a parent cannot have children and vice-versa (ensured by the controller). For clarity, let's call Disciplines without an assigned parent the Parent Disciplines, those with an assigned parent the Child Disciplines. There is a Degree model. Each Degree is assigned a Child Discipline. E.g. a "BSc Anthropology" would be assigned to the "Anthropology" Discipline, never the "Social Sciences" Discipline directly. Discipline: class Discipline < ActiveRecord::Base belongs_to :parent, class_name: "Discipline" has_many :children, class_name: "Discipline", foreign_key: "parent_id" has_many :degrees ... end
Degree: class Degree < ActiveRecord::Base belongs_to :discipline ... end
How do I now retrieve all the Degrees belonging to a certain Parent Discipline? Preferably I would like to avoid SQL code altogether and only use Rails code for it. I'd guess this will go via a .join() but I cannot get my head around the logic I must apply here. Thank you! |
| Query HSTORE key based on data type Posted: 13 Jun 2016 07:25 AM PDT Trying to use PostgreSQL HSTORE data structure. Users can add number of custom attributes for their records e.g:- source, counter_number, received_at etc. Now we need to provide a filtering option based on the data type added. e.g:- received_at is datetime column so we will provide datetime specific filter. If counter_number is integer then we will provide integer type filters. Data type for every column is saved in separate table, that is used as reference while querying records. Now if someone add string in datetime type field it will crash due to type conversion. Is there a way to query in hstore that will query only records those are of some certain data type e.g:- Query only those rows those are having counter_number as integer. |
| How to force an html element to load first - RoR Posted: 13 Jun 2016 07:23 AM PDT Im have 2 drop down menus on my website that use the isotope plugin to filter items on the site. The problem is that those drop down menus take time to appear on the page, which is a problem especially on mobile devices because users might scroll down before they are even loaded and completely miss them. You can see the problem for yourself on my website www.shopwatchkw.com. The drop down menus are displayed in red and blue. How can I make it so the two drop down menus either load faster or before the rest of the page is loaded so that users wont potentially miss it? I should point out that the options for the drop down menu are being populated through database requests from a Category and Mall model, and they are not static html text. Here is the relevant code: index.html.erb <div class="filter-select"> <div id="filterGroup"> <select class="filter option-set selectpicker" data-filter-group="category" data-style="btn-category" data-size="false" title=" Choose a Category.."> <option data-filter-value="" selected="selected">All Categories</option> <% @categories.each do |category| %> <option data-filter-value=".category<%= category.id %>"><%= category.category_type %></option> <% end %> </select> <select class="filter option-set selectpicker" data-filter-group="location" data-style="btn-location" data-size="false" title="Choose a Location.."> <option data-filter-value="" selected="selected">All Locations</option> <% @malls.each do |mall| %> <option data-filter-value=".mall<%= mall.id %>"><%= mall.name %></option> <% end %> </select> </div> </div>
I'm not sure what other code would be useful but please let me know if you need more specific code. |
| Rails formatting logs to use with aws-logs and CloudWatch Posted: 13 Jun 2016 07:18 AM PDT AWS has this very cool log collection tool using aws-logs However, I do not understand how I can format my log / configure the tool to be smarter and regroup the same error message.

| Is there any software out there to visually represent the branches, directories and tags created as I develop a Ruby on Rails program? Posted: 13 Jun 2016 07:11 AM PDT I am looking for software to illustrate all the directories and branches I have created during a Ruby on Rails program but cannot find any. I feel it would be really useful to have a graphical representation of what branch/directory I am currently in relative to the others etc. Also to have an illustration of the various tags and versions I have created and be able to click back and forth between them. Does anyone else think this would be useful at all?? And if software like this exists could you post a link? Thanks in advance. |

| Error with Rails Mailer Posted: 13 Jun 2016 06:31 AM PDT I've written a code so that the attendees of a conference receive an email whenever a call is made. My mailer code is this: def send_attendee_invite(conference_id) # Setting value for attendees which is an array of user type @attendees.each do |attendee| @attendee = attendee subject = "Some Subject specific to attendee" mail.attachments['attachment.ics'] = { mime_type: 'text/calendar', content: someattachment} mail(to: @attendee.email, subject: subject) end end
The test I've written for this is: test "mail to an attendee for a conference" do conference = conferences(:test) email = ABCMailer.send_attendee_invite(conference.id).deliver_now assert_not ActionMailer::Base.deliveries.empty? assert_equal [Settings.mail.default_from], email.from assert_equal ["attendee_1@mail.com"], email.to assert_includes email.body.encoded, "You have been invited to a conference call scheduled by Requesor." end
Mail goes to attendee_1's email but has the following body \r\n----==_mimepart_575ea732df68e_144d8df98c2091b\r\nContent-Type: text/plain;\r\n charset=UTF-8\r\nContent-Transfer-Encoding: 7bit\r\n\r\n<p></p>Hi Attendee_2, <p></p>You have been invited to a conference call scheduled by Requestor. <p></p>The invite has been attached in this email.

The html.slim page is being called thrice instead of once and so the body appears three times in the same email. Secondly, for some reason, instead of sending two emails for two attendees, it sends one email to attendee_1's email id with the body that must appear in attendee_2's email. Attendee_2 doesn't get his own email at all. I'm calling this mailer this way: ABCMailer.send_attendee_invite(conference.id).deliver_now

| Overriding Spree views with deface Posted: 13 Jun 2016 05:09 AM PDT I have a spree view I want to override with deface. It consists of three li tags.

For session controller my view/sessions/create.html.erb file is: <h4>Database contents here:</h4> <table> <tr> <th>ID</th> <th>AGE</th> <th>NAME</th> </tr> <% @data.each do |data| %> <tr> <td><%= data.id %></td> <td><%= data.age %></td> <td><%= data.name %></td> </tr> <% end %> </table> <div> <%= form_tag :method => :get do %> <%= button_tag type: 'submit' do %> <%= content_tag :div do%> <h4>View Data </h4><h4><%= @num %></h4> <% end %> <% end %> <% end %> </div>
And my contollers/sessions_controller file is: class SessionsController < ApplicationController def new end def index end def create user = User.authenticate(params[:email], params[:password]) @data=Information.all @num=Information.count() @tym=Time.now.getutc if user session[:user_id] = user.id #redirect_to root_url, :notice => "Logged in!" #this part is for showing the content of the information table respond_to do |format| format.html format.xml { render xml: @data } end else flash.now.alert = "Invalid email or password" render "new" end end def destroy session[:user_id] = nil redirect_to root_url, :notice => "Logged out!" end end

| Deploying with Capistrano, nginx and puma Posted: 13 Jun 2016 06:28 AM PDT I followed this tutorial: https://www.digitalocean.com/community/tutorials/deploying-a-rails-app-on-ubuntu-14-04-with-capistrano-nginx-and-puma to learn how to deploy my project to a staging environment everything works great except the server won't restart after I deploy and still runs on the old version. - I'm running the staging environment from the /current deployed folder, by using "rails s -e staging"
- I'm running sidekiq, redis and another task using "RAILS_ENV=staging foreman start"
- deploying using "cap staging deploy" from my development project folder
am I doing anything wrong? This project was passed to me by another team and I can't contact them for questions so there may be information missing here. I think I'm doing something wrong in this process of starting the server and deploying but I haven't found any information on this procedure on the web When I start the server using "RAILS_ENV=staging rails s puma" from /current I don't get a puma process, but I see the server terminal running and I the website is working. But when I do "cap staging puma:start" from the development terminal I do see a puma process but no server terminal and I the site is not working.

| How to access google sheet api using Roo gem? Posted: 13 Jun 2016 04:12 AM PDT I have set up OAuth 2.0 from google developer console(as there were three type of credentials, suggest if any issue) and enabled Sheet API, On trying below snippet from Rails console, Roo::Google.new(sheet_key, access_token: token).first_row
throwing below error, Attempting refresh of access token & retry of request Google::APIClient::AuthorizationError: Invalid Credentials
I am passing Client secret copied from dev-console I have taken a reference from row-google gem initialize method how can i fix this error? PS: Do I have to be owner of the sheet or edit access will suffice, by the way I am accessing my owned Sheet. :) Thanks! |
| Rails - auto form submit on Devise login, undefined method `permit' Posted: 13 Jun 2016 04:51 AM PDT I am experimenting with a Rails app - I am using Devise for user login, and I am trying to set it up so that every time a user successfully logs in, a specific entry is automatically inserted into a model called reports. In my Devise session controller, I have the following actions related to a successful user login: def create self.resource = warden.authenticate!(auth_options) sign_in(resource_name, resource) yield resource if block_given? respond_with resource, location: after_sign_in_path_for(resource) end def after_sign_in_path_for(resource) Report.create(report_params({"comment" => "user logged in"})) end private def report_params(params) params.permit(:comment) end
So, if that's not clear, what I mean to do is create a new entry in reports every time a user logs in, and that entry will always read "user logged in". However, when I try to run this, I get the following error: undefined method `permit' for {"comment"=>"user logged in"}:Hash
I realize that this exact operation may seem a bit pointless or redundant - as I said, I'm just experimenting, but getting this right may help me to restructure a different app that I was working on (thinking about JSONs in place of this fixed entry). If someone could explain the meaning of this error and help me figure out what I am doing wrong (or if this is the best way to accomplish such a task), that would be much appreciated. |
| Model not saving Paperclip avatar data Posted: 13 Jun 2016 04:56 AM PDT I have a Rails 4 app that scrapes a given web page and saves the data in a Link model. I'm using the Paperclip gem in conjunction with the after_save callback to get the url of the image and then upload it to AWS S3. This all works fine and I can view the image in my S3 bucket. The problem I have is that the avatar_file_name, avatar_content_type, avatar_file_size and avatar_updated_at columns in the db remain nil as if there is no :avatar attached the the Link link.rb:
class Link < ActiveRecord::Base after_save :picture_from_url has_attached_file :avatar, styles: { medium: "300x300>", thumb: "100x100>" }, default_url: "/images/:style/missing.png" validates_attachment_content_type :avatar, content_type: /\Aimage\/.*\Z/ ... def picture_from_url self.avatar = URI.parse(self.image_url) end end
UPDATE: with Controller code class LinksController < ApplicationController ... def new @link = Link.new end def create @link = Link.create(link_params) if @link.save flash[:success] = "Thanks for your submission!" redirect_to link_path(@link) else render :new end end private def link_params params.require(:link).permit(:title, :url, :content, :tag_list, :category, :image_url, :avatar).merge(user_id: current_user.id, author_first_name: current_user.first_name) end end
