Add index to Rails form object Posted: 05 Nov 2016 08:13 AM PDT Add a index when using Rails Form Objects to update multiple records Issue I'm having is when I need to create multiple records for the same model The hash created by the form overwrites identical models form_for @post_form do |f| ... f.text_field :article f.text_field :article ... Parameters: {"post_form"=>{"article"=>"article 2"}} I'm using a Form Object to update multiple different models with some of the fields being created client side with ajax I need a way to add an index to get around the overwriting when creating multiple records with the same model.

gocardless webhook signature mismatch Posted: 05 Nov 2016 08:12 AM PDT I am going through the gocardless getting started guide, but when I try to setup a webhook (sandbox mode), I don't get the correct value. The code is copy-pasted from https://developer.gocardless.com/getting-started/api/staying-up-to-date-with-webhooks/#building-a-webhook-handler and looks like this computed_signature = OpenSSL::HMAC.hexdigest(OpenSSL::Digest.new('sha256'), secret, request.raw_post) provided_signature = request.headers['Webhook-Signature'] Rack::Utils.secure_compare(provided_signature, computed_signature) # => false What am I missing? Thanks for any help

How to deploy a Rails application through Core FTP Posted: 05 Nov 2016 07:39 AM PDT I am trying to deploy my Rails application to a hosting site through Core FTP.

Why is activerecord-import using type_cast_for_database instead of value_for_database Posted: 05 Nov 2016 04:54 AM PDT Tracking Rails 5 source code, it turns out that its way to get SQL value for database of a column can be simplified as follows: ActiveRecord::Base.connection.quote(attribute.value_for_database) https://github.com/rails/rails/blob/master/activerecord/lib/active_record/attribute.rb However I noticed that activerecord-import gem, uses another method type_cast_for_database(attr_name, value), and it passes it the value of the attribute before_type_cast https://github.com/zdennis/activerecord-import/blob/master/lib/activerecord-import/import.rb#L639 Also I noticed that calling type_cast_for_database(column_name, value_before_typecast) is faster than calling attribute.value_for_database as the former is reduced to calling type.serialize(value_before_type_cast), while the latter is reduced to type.serialize(type_cast(value_before_type_cast)) So why does rails uses the extra step of type casting the attribute value before passing it to serialize? As it appears that activerecord-import works fine without the need of this step.

Ruby-on-rails: are there any other way to make page statefull except use session? Posted: 05 Nov 2016 07:29 AM PDT I am creating search form for model with some tabs, radiobuttons, dropbox, etc. I use index action for searching and sorting. Parameters for searching is persisted in params. It works while I stay in the same index view. But if I had to visit other page and then come back to search page again, params doesn't work and state is not persisted. I know I can do it with session, but suppose I would have more search forms for another models and so all that params goes into session. Doesn't it make session messy? So question is: Is there other reasonable way to persist page state (but I don't want to put into database)

The associations are: Proposal has_many :images, as: :imageable accepts_nested_attributes_for :images, reject_if: :all_blank, allow_destroy: true Image belongs_to :imageable, :polymorphic => true, optional: true My view partial has: <!-- GALLERY --> <div id="myCarousel" class="carousel slide" data-ride="carousel"> <!-- <div class="carousel-inner" role="listbox"> --> <% @images.each do |gallery| %> <% if gallery == @images.order(created_at: :asc).first%> <div class="item active"> <%= carousel_for(gallery) %> <%= image_tag(gallery.picture.url, :class => "carousel_image", :style => "text-align: center" ) %> <div class="carousel_caption"> <p style="text-align: center"><%= gallery.comment.humanize %></p> <p style="text-align: center"><%= gallery.credit %></p> </div> </div> <% else %> <div class="item"> <%= carousel_for(gallery) %> <%= image_tag(gallery.picture, :class => "carousel_image") %> <div class="carousel_caption"> <p style="text-align: center"><%= gallery.comment.humanize %></p> <p style="text-align: center"><%= gallery.credit %></p> </div> </div> <% end %> <% end %> <!-- </div> --> <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev"> <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span> <span class="sr-only">Previous</span> </a> <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next"> <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span> <span class="sr-only">Next</span> </a> </div> <!-- /GALLERY --> Helper has: module CarouselHelper def carousel_for(images) Carousel.new(self, images).html end class Carousel def initialize(view, images) @view, @images = view, images @uid = SecureRandom.hex(6) end def html content = safe_join([indicators, slides, controls]) content_tag(:div, content, id: uid, class: 'carousel slide') end private attr_accessor :view, :images, :uid delegate :link_to, :content_tag, :image_tag, :safe_join, to: :view def indicators items = images.count.times.map { |index| indicator_tag(index) } content_tag(:ol, safe_join(items), class: 'carousel-indicators') end def indicator_tag(index) options = { class: (index.zero? ?

Using Devise to set up referrals issue Posted: 05 Nov 2016 01:58 AM PDT I am running devise to handle user authentication, I am wondering if any of you have experience in setting one up with devise? I found this small post which is nice but am a bit confused as to how this line works: def capture_referal session[:referral] = params[:referral] if params[:referral] end I can't see in that example where I am meant to input in the params[:referral] ? Also this seems kind of simple, is the referral token going to be the referral code the user sets e.g RAILSDEVISE or will it be the entire URL x.com?ref=RAILSDEVISE? If anyone has a github of a rails referral program i'd love to check it out(:

Preview last uploaded image Posted: 05 Nov 2016 03:35 AM PDT I'm using an old project where I could upload many images but for this one, I only need just one. When uploaded, I should see what's uploaded (preview). When first uploaded, I see the image. If uploaded a different image, I still see the first image. I dont want that, I need to preview the last uploaded image. JavaScript: $('.receipt.upload').on('change', function(e) { let id = e.target.id; let files = e.target.files; let image = files[0]; let reader = new FileReader(); reader.onload = function(file) { let img = new Image(); console.log(file); img.src = file.target.result; $('.'+id).replaceWith(img); } reader.readAsDataURL(image); //console.log(files); }); Rails html.erb: <div> <%= image_tag('/assets/receipt/missing-receipt.jpg', class: "receipt#{contract.id}") %> </div> // Inside a form <div> <%= f.file_field :receipt, id: "receipt#{contract.id}" , class: "receipt upload"%> </div> Change these makes no difference: let files = e.target.files[0]; let image = files;

Rails 5: Two forms for one polymorphic model on a single view Posted: 04 Nov 2016 11:04 PM PDT I have a polymorphic model, Comment, comment on a Post or another Comment (reddit style). I want a user to be able to comment directly to the post with a commentable_id of @post.id and a commentable_type of @post.class.name OR be able to comment on another comment on the same page, however, using @comment.id and @comment.class.name Is there a way to dynamically change between @post or @comment depending on where the form is?

Rails assets usage clarification Posted: 04 Nov 2016 11:20 PM PDT I am new to rails and I'm a bit confused about how assets are loaded. I can get things working but I would like to understand what really happens behind the scenes. I have been reading the documentation but there are things that I don't understand completely. MANIFEST FILE First thing that confuses me is the usage of manifest files. For instance if in my app/assets/javascripts/application.js file I have: //= require_tree . Rails documentation says: tells Sprockets to recursively include all JavaScript files in the specified directory into the output What isn't clear to me is which directory? app/assets/javascripts/? Does that mean that if I add a file in app/assets/javascripts/ it will be loaded and served? If I add a gem that requires to add a file example.js I need to add to the manifest file: //= require example.js But why is this necessary if //= require_tree already loads and serve files in app/assets/javascripts/ which is the location where I have put my example.js? Ok that allows me to specify the order if later I add more requires. But other than that? HTML FILE And then the script to be included in application.html.erb <%= javascript_include_tag ('application'), 'data-turbolinks-track' => true %> I understand this loads the application.js file mentioned above and therefore the various //= require in it. Sometimes happens that is required to script the particular file as: <script src="js/example.js"></script> Is this scenario wouldn't be <script src="js/example.js"></script> doing the exact same thing of //= require example.js? PUBLIC VS APP ASSETS I understand that if I place my example.js file on public/assets folder it won't be compiled but served separately. Why would I do that? Is it reasonable to do it in case a file is not served correctly when concatenated and compiled and works only if served separated? In other words, if I include a .js file on app/assest and it has problems to load or break things, is it worth to try to remove it from there and move it to public/assets or does this just not make sense? APP ASSETS VS VENDOR ASSETS On which scenario should I add a file to vendor assets instead of app assets? What is the difference between adding it to a place or another? And in my vendor/assets/javascripts I have only an empty .keep file. So there'n so such thing as manifest file on app/assets. How are files in this folder referenced then?
