| Update Nested Attributes Posted: 27 Dec 2016 07:38 AM PST I have a form with nested attributes. It all works perfect for creating a new product and at the same time creating a consumption record for that product in a different table. The problem is when i want to edit the product.. It does a SQL UPDATE for the product object and SQL INSERT for the nested consumptions object. One product has many consumptions so how can i program this to find and update all the consumptions associated with this product. Form View <%= form_for(@new_product) do |f| %> <div class="container"> <div class="name-category"> <h1>New Product</h1> <div class="field"> <%= f.label :name %><br> <%= f.text_field :name %> </div> <div class="field"> <%= f.label :price %><br> <%= f.number_field :price %> </div> <div class="field"> <%= f.select :category_id, Category.all.collect { |c| [ c.name, c.id ] } %> </div> </div> <div class="add-ingredients"> <div class="add-button"> <p id="more">Add Ingredients</p> </div> <%= f.fields_for :consumptions, @consumptions do |ff| %> <div id="new-ingredients-container"> <div class="titles"> <p>Ingrediente</p> <p>Consumo</p> </div> <div class="ingredients-row"> <%= ff.select :supply_id, Supply.all.collect { |c| [ c.name, c.id ] }, {}, {class: "ingredients-select"} %> <%= ff.number_field :consumption %> </div> </div> <% end %> </div> </div> <div class="actions"> <%= f.submit %> </div> <% end %>
Product Controller def new @new_product = Product.new @consumptions = @new_product.consumptions.build end def update @product = Product.find(params[:id]) @consumptions = @product.consumptions @consumptions.each do |c| c.update(params.permit(:consumption_id, :supply_id, :product_id, :consumption)) end 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

| rails link_to on overlay div Posted: 27 Dec 2016 07:33 AM PST I have a div structured like so: <% @posts.each do |post| %> <!-- Shot --> <div class="col-xs-12 col-sm-6 col-md-4 col-lg-3"> <div class="shot shot-minimal"> <div class="shot-preview"> <a class="img" href="shot-gallery.html"><img src="http://rwdtow.stdout.in/img/avatar-icon.png" alt=""></a> <a class="text-overlay"> <span class="heading"><%= post.tite %></span> <span class="desc"><%= post.shortdescription %></span> <time datetime="2016-02-04 22:30">7 hours ago</time> </a> </div> <div class="shot-detail"> <div class="shot-info"> <p><%= post.title %></p> </div> <ul class="shot-stats"> <li><i class="fa fa-eye"></i><span>6.3k</span></li> <li><a class="like" href="#"><i class="fa fa-heart"></i><span>1.2k</span></a></li> </ul> </div> </div> </div> <!-- END Shot --> <% end %>
In the above div i have an overlay: <a class="text-overlay"> <span class="heading"><%= post.tite %></span> <span class="desc"><%= post.shortdescription %></span> <time datetime="2016-02-04 22:30">7 hours ago</time> </a>
So i placed a link_to with the overlay, so the text overlays, the text is clickable: <%= link_to post, class:"text-overlay" do %> <span class="heading"><%= post.tite %></span> <span class="desc"><%= post.shortdescription %></span> <time datetime="2016-02-04 22:30">7 hours ago</time> <% end %>
The overlay works correct, but when i click on it, it does not take me to the show action for the post. Heres how my final code looks: <% @posts.each do |post| %> <!-- Shot --> <div class="col-xs-12 col-sm-6 col-md-4 col-lg-3"> <div class="shot shot-minimal"> <div class="shot-preview"> <a class="img" href="shot-gallery.html"><img src="http://rwdtow.stdout.in/img/avatar-icon.png" alt=""></a> <%= link_to post, class:"text-overlay" do %> <span class="heading"><%= post.tite %></span> <span class="desc"><%= post.shortdescription %></span> <time datetime="2016-02-04 22:30">7 hours ago</time> <% end %> </div> <div class="shot-detail"> <div class="shot-info"> <p><%= post.title %></p> </div> <ul class="shot-stats"> <li><i class="fa fa-eye"></i><span>6.3k</span></li> <li><a class="like" href="#"><i class="fa fa-heart"></i><span>1.2k</span></a></li> </ul> </div> </div> </div> <!-- END Shot --> <% end %>

| Rails association with a (non-activerecord) class (not a object/row) Posted: 27 Dec 2016 07:24 AM PST The problem: People may have many types of degrees (bachelor, master, phd, etc...). In my country, some degrees includes another. Ex.: Superior Degree may be either bachelor or licentiate. I'd like to create this structure in a class hierarchy: Bachelor < Superior < Degree Licentiate < Superior < Degree Master < Degree PHD < Degree
Those classes don't need to have rows stored in the Database, but I'd like to associate them with some ActiveRecord objects of other classes. Should I just store classes name as strings? |
| Ruby on Rails: can you store regex in a variable? [duplicate] Posted: 27 Dec 2016 07:16 AM PST This question already has an answer here: I check the format of my input against a custom regex. I use this regex in more than one place in my model, so I want to store it in a variable. MY_REGEX = '/\A*blablabla*\Z/' validates_format_of :my_input, :with => MY_REGEX, :allow_blank => true ... ... if somethingelse =~ MY_REGEX: # more code end
Which yields: ArgumentError (A regular expression or a proc or lambda must be supplied as :with)

| Dynamic concerns for a Rails model Posted: 27 Dec 2016 06:41 AM PST For a project I needed the ability to upload video's to a video server. At first the scope was to only upload to a Kaltura video server. To enable this, I created a simple concern that added some callback methods to the model which handle the uploads. These callback methods (specifically for Kaltura) are being loaded like so: class Videofile < ActiveRecord::Base include KalturaBox::Entry end
And they contain basics like this (simplified version): module KalturaBox module Entry extend ActiveSupport::Concern included do before_save :create_kaltura_item, on: :create private def create_kaltura_item puts 'create callback called' self.upload end end end
Now the scope has broadened, and I was asked to also include Vimeo uploads as an option. Is it possible to dynamically embed the concerns based on an attribute of the model, or should I consider using STI instead? I was thinking about creating a drop-down called "video_type". How do I include the correct code based on that attribute? |

| How to add new attachinary image to an instance instead of replacing the whole array in Rails 5 Posted: 27 Dec 2016 07:27 AM PST This might be a stupid question since I can't find it already asked here but I can't find a solution no matter how I tried. I use Rails 5 with Cloudinary and Attachinary gems. I have a model PointOfInterest with has_attachments :photos, maximum: 3
Everything works fine if photos are uploaded at once (with simple_form). But I want my users to be able to upload photos sequentially ; for instance 1 photo at the creation of the point_of_interest and then add 2 more later on edit. Unfortunately the update method deletes the attachments before saving the new input. I ended up building an array with the old attachment and new one from the update and tried to overwrite the attachments: @point_of_interest.photos = new_photoset
but I get a Runtime error => Can't modify frozen hash. I also just realized my new_photoset array mixes Attachinary::File (previous image) and Attachinary::File::ActiveRecord_Associations_CollectionProxy (new image) so I'm pretty sure I'm not on the right track. I tries many different approaches and I don't find the Attachinary docs very helpful. Or maybe I should investigate on the jQuery-File-Upload side? Any help will be much appreciated. |

| multiple user types with self references rails Posted: 27 Dec 2016 03:53 AM PST I am working on an app in rails where I need to make multiple types of users. I am using Devise gem for authentication. Now let me give you an overview what I am trying to achieve and could not for past whole week. First, I want 2 types of users. Let us call them Client and Developer as shown below. class Client < ActiveRecord::Base end class Developer < ActiveRecord::Base end
Now, these 2 users have many to many relation with each other. A client can have many developers and a developer can also work for many clients. So, for that, we will need a middle table as well. Let us call it client_developer_join. So, let us update our models accordingly. class Client < ActiveRecord::Base has_many :developers, through: :client_developer_joins, dependent: :nullify has_many :client_developer_joins, dependent: :destroy end class Developer < ActiveRecord::Base has_many :clients, through: :client_developer_joins, dependent: :nullify has_many :client_developer_joins, dependent: :destroy end class ClientDeveloperJoin < ActiveRecord::Base belongs_to :client belongs_to :developer end
Important: Now, what I want is that when a user sign up, he will be given the ability to choose whether to sign up as a Client or a Developer using radio buttton or some other good looking thing. There will also be a third option named "Both". In that case, user will have the option to switch from Client to Developer and vice versa whenever he wants. How can I acheive without creating multiple sign up and sign in forms for each type of user and give them the ability to switch. I have looked into STI (Single Table Inheritance) and all the questions on StackoverFlow related to that but could not solve the problem. One solution that I think is ideal but do not know how to achieve is to have seperate devise models for each type of user but that will create different sign up and sign in forms for that. I do not want that and it will also not give me the ability to switch from the one type to another type. |

| Render images from enother project cause 404(not found) error Posted: 27 Dec 2016 05:59 AM PST Hello I have to separate projects, images_project and site_project. site_project should render images from images_project only in development environment from local machine. In production it does by SDN. I share images_project path from secrets in 'praser_path'. I added images path to assets config in site_project: # config/initializers/assets.rb if Rails.env.development? && Rails.application.secrets.parser_path # share parser images for admin Rails.application.config.assets.paths.push( File.join( Rails.application.secrets.parser_path, 'public', 'uploads') ) Rails.application.config.assets.precompile += %w( advert_image/** ) end
My model looks for images in local machine # model/image.rb def file_url(size=nil) if Rails.env.development? && Rails.application.secrets.parser_path File.join( Rails.application.secrets.parser_path, 'public', file.url(size)) else REMOTE_HOST + file.url(size) end end
But when a page with my images renders it processes 404 for all images with this error: http://localhost:3000/Users/nick/CODE/work/biz/parser/public/uploads/advert_image/images/374/micro_3117094366.jpg Failed to load resource: the server responded with a status of 404 (Not Found) I know that the follow link is bad and images is in file:///Users/nick/CODE/work/biz/parser/public/uploads/advert_image/images/374/micro_3117094366.jpg What should I do to get around the server and render images straight from local machine? |
| devise_ldap_authenticatable not wotking Posted: 27 Dec 2016 01:54 AM PST Try yo use devise_ldap_authenticatable gem in my app, but it's not working. Authorization page return invalid email or password error and Completed 401 Unauthorized in 1ms (ActiveRecord: 0.0ms) in server logs. ldap.yml authorizations: &AUTHORIZATIONS allow_unauthenticated_bind: false group_base: "dc=dvfu,dc=ru" development: host: dc.dvfu.ru port: 389 attribute: cn base: dc=dvfu,dc=ru admin_user: CN=usertest,OU=Service,DC=dvfu,DC=ru admin_password: 'password' ssl: no <<: *AUTHORIZATIONS
And i have no idea how to debug it, devise_ldap_authenticatable documentation is poor. Oh, maybe it's important i have username or email authethication in my app, so have to rewrtie one line in on class: auth_key = self.authentication_keys.first was chanhged to auth_key = :username Devise::Models::LdapAuthenticatable::ClassMethods.class_eval do def find_for_ldap_authentication(attributes={}) #auth_key = self.authentication_keys.first auth_key = :username return nil unless attributes[auth_key].present? auth_key_value = (self.case_insensitive_keys || []).include?(auth_key) ? attributes[auth_key].downcase : attributes[auth_key] auth_key_value = (self.strip_whitespace_keys || []).include?(auth_key) ? auth_key_value.strip : auth_key_value resource = where(auth_key => auth_key_value).first if resource.blank? resource = new resource[auth_key] = auth_key_value resource.password = attributes[:password] end if ::Devise.ldap_create_user && resource.new_record? && resource.valid_ldap_authentication?(attributes[:password]) resource.ldap_before_save if resource.respond_to?(:ldap_before_save) resource.save! end resource end end

| ruby on rails secuirity [on hold] Posted: 27 Dec 2016 01:40 AM PST In term to performing penetration testing with one of the tool Vega then its giving error of flag not set of cookie. And then I have set it to secure: true for a session in the config file but still same response from Vega. Log of Vega is below: Vega has detected that this cookie was set without the Secure flag. When the Secure flag is set, the browser will only transmit the cookie back to the server over HTTPS. However, when this flag is not set, the cookie may be transmitted over unencrypted HTTP. This may allow the cookie to be observed in transit. Please let me know if any suggestion..Quick response will help me more Thanks |

| Render the submit button from another controller Posted: 27 Dec 2016 01:17 AM PST I'm trying to render form(form2) into another form(form1). Both forms have the submit button. Both buttons work like submit button but only for form1 has the error "NoMethodError at form1: undefined method `save' for nil:NilClass" and params: "form1_params"=>{"form1_title"=>"title1", "form1_count"=>"1"}, "form2_params"=>{"form2r_name"=>"name2", "form2_value"=>"1"}, "commit"=>"add", "controller"=>"form1", "action"=>"create"} form1: = form_for @form1 do |f| = render 'form2/new' = f.submit 'Submit', class: 'btn btn-success', id: 'sav_bonuse1'
form2: = form_for(@form2, url: form2_path) do |f| = f.submit 'Submit', class: 'btn btn-success', id: "save"
create action in form1_controller: def create @form1 = Form1.new(form1_params) if @form1.save flash[:success] else flash[:error] end redirect_to form1_path end
How I can fix both this buttons? |
