| passing data from one rails application to another using apache camel-cxf-rest in servicemix Posted: 24 May 2016 07:09 AM PDT I have two Rails applications, lets say app1 and app2. I have to send some data from app1 to app2 using Apache ServiceMix(actually i have to send this data to 2 applications from ServiceMix - but for now lets stick to one application). I am using the camel-cxf-rest example inside ServiceMix/example/camel/ folder of ServiceMix. And in this there is the implementation of Person class as restful service(we can do POST of person and GET of person from other application.) So my app1 code looks like this: def post_demo url_string = "http://localhost:8989/rest/personservice/person/post/" xml_string = "<person><age>21</age><id>1</id><name>dharma</name> </person>" uri = URI.parse url_string request = Net::HTTP::Post.new uri.path request.body = xml_string request.content_type = 'text/xml' @response = Net::HTTP.new(uri.host, uri.port).start { |http| http.request request } end
so i am making a post request from the app1 one and it successfully posts this person to the database in the servicemix. Now i use get from app2 as follows: def get_demo url = URI.parse('http://localhost:8989/rest/personservice/person/get/1') req = Net::HTTP::Get.new(url.to_s) @res = Net::HTTP::start(url.host, url.port){|http| http.request(req) } puts @res.body end
So - till now what i am doing is making POST request from app1 and storing the data in the servicemix and making GET request from the app2 to get these data- But what i really want it whenever I make POST request to ServiceMix I want it to get forwarded to app2 so that i don't have to make GET request from app2. I dont have full idea but maybe apache camel routing is one solution.Thank you for any help in advance. |

| search function for conversations in ruby on rails Posted: 24 May 2016 06:36 AM PDT I m new to rails. I would like to add a search function for my rails app. the user can search for the conversations that he made with other users. in that search, he can type keywords of the messages or the user name that he chatted. Can some one guide me through this... conversation.rb is, class Conversation < ActiveRecord::Base belongs_to :sender, foreign_key: :sender_id, class_name: 'User' belongs_to :recipient, foreign_key: :recipient_id, class_name: 'User' has_many :messages, dependent: :destroy validates_uniqueness_of :sender_id, scope: :recipient_id scope :involving, -> (user) do where("conversations.sender_id = ?

OR (conversations.sender_id = ? AND conversations.recipient_id = ?)", sender_id, recipient_id, recipient_id, sender_id) end end
message.rb is, class Message < ActiveRecord::Base belongs_to :conversation belongs_to :user validates_presence_of :content, :conversation_id, :user_id def message_time created_at.strftime("%v") end end
conversations_controller.rb is, class ConversationsController < ApplicationController before_action :authenticate_user! def index @users = User.all @conversations = Conversation.involving(current_user) end def create if Conversation.between(params[:sender_id], params[:recipient_id]).present? @conversation = Conversation.between(params[:sender_id], params[:recipient_id]).first else @conversation = Conversation.create(conversation_params) end redirect_to conversation_messages_path(@conversation) end private def conversation_params params.permit(:sender_id, :recipient_id) end end

Can someone guide me to write the functionality for search and view the results of the search. i have tried in two different types but not worked. Thanks in advance |

| Rails quickly find record where has_many associations exactly match array of association ids Posted: 24 May 2016 06:27 AM PDT I've got a Product model which has_many OptionValue records, which describe color, size, etc. Within my code, I need to query the Product model where the product.option_values.pluck(:id) array exactly matches an array of (e.g.) options = [1, 6, 4]. Running something like Product.includes(:option_values).where(option_values: { id: options_array }) returns all values that match at least one element of the options array, rather than all of them. I've developed an inefficient way of getting the record I need, as follows: Product.all.each { |v| return v if v.option_values.pluck(:id).sort == options_array.sort }
Obviously the above is way ott and I'm sure there's a simpler way to handle this, and I'm happy to use ActiveRecord or a straight SQL query (though I'm not too hot on the latter, so haven't come up with anything yet). Any advice on the best way of achieving this greatly appreciated. Not sure I've explained this perfectly, so please comment if you've any questions. Thanks in advance, Steve. |

| Form routes to the wrong action causing errors Posted: 24 May 2016 05:57 AM PDT I created an itinerary web app that allows a user to upload itineraries and 'download' other users itineraries into their profile. For whatever reason instead of my download button routing to the downloads controller, it routes to the itineraries controller and breaks my app. I can't seem to figure out why - hope you can help. Here's the download button on the itinerary show page: Itineraries/show.html.erb <% if logged_in? %> <% unless current_user.downloaded?(@itinerary) %> <%= render 'download' %> <% end %> <% else %> <p> You need to be logged in to download this. </p> <% end %>
The partial rendered should route to the download controller: itineraries/_download.html.erb <%= form_for(current_user.downloadeds.build) do |f| %> <div><%= hidden_field_tag :downloaded_id, @itinerary.id %></div> <%= f.submit "Download", class: "btn btn-primary" %> <% end %> Class DownloadsController < ApplicationController before_action :logged_in_user def create #download id is established in the download form @itinerary = Itinerary.find(params[:downloaded_id]) current_user.download(@itinerary) redirect_to @itinerary end
Instead it routes to the itineraries controller and this returns the following error - ActionController error - param is missing or value is empty: itinerary itineraries_controller.erb def create @itinerary = current_user.itineraries.build(itinerary_params) #@user = User.find(params[:id]) if @itinerary.save # render the page with the users itineraries flash[:success] = "Your itinerary has been added!" redirect_to request.referrer || current_user else #show the add itinerary page flash[:error] = @itinerary.errors.full_messages render 'new' end end
Lastly here are my routes: routes # You can have the root of your site routed with "root" root 'static_pages#home' get 'signup' => 'users#new' get 'help' => 'static_pages#help' get 'about' => 'static_pages#about' get 'login' => 'sessions#new' post 'login' => 'sessions#create' delete 'logout' => 'sessions#destroy' resources :users resources :itineraries do resources :reviews end resources :downloads, only: [:create, :show] mount PdfjsViewer::Rails::Engine => "/pdfjs", as: 'pdfjs'

| Add a reference column using migration having non standard primary key column Posted: 24 May 2016 06:23 AM PDT I have a model which has a non-rails conventional primary key. class Guoid < ActiveRecord::Base self.primary_key = :guoid end
and related migration class CreateGuoids < ActiveRecord::Migration def change create_table :guoids, id: false do |t| t.integer :guoid, limit: 8, auto_increment: true, primary_key: true t.integer :parent_guoid, limit: 8 t.string :resource_type, limit: 60 end end end

and related migration class CreateContents < ActiveRecord::Migration def change create_table :contents, id: false do |t| t.references :content_unit, index: true, foreign_key: true t.references :user, index: true, foreign_key: true end end end
When I run the migration, I am getting following error.

I am expecting to create content_unit_guoid foreign key in contents table referencing guoid in guoids table. I used activerecord-mysql-awesome gem to work well with non-rails convention primary keys. Here is a trigger which first creates a record in guids table and use it's pk as pk of the target table.

| rails has_many :through association doesnt work Posted: 24 May 2016 04:35 AM PDT I have a problem with a has_many through association. I have an account model which has many offices and hotels account.rb : class Account < ActiveRecord::Base # associations has_many :partnerships, through: :hotels, dependent: :destroy has_many :partnerships, through: :offices, dependent: :destroy has_many :users, through: :hotels, dependent: :destroy has_many :hotels, dependent: :destroy has_many :offices, dependent: :destroy belongs_to :admin, class_name: "User", foreign_key: "admin_user_id", dependent: :destroy
then I have a partnerships table which is a join table between hotels and offices thus both hotel and office have many partnerships: class Hotel < ActiveRecord::Base has_many :partnerships belongs_to :account has_and_belongs_to_many :user class Office < ActiveRecord::Base belongs_to :account has_and_belongs_to_many :users has_many :partnerships
and finally my partnership model : class Partnership < ActiveRecord::Base belongs_to :hotel belongs_to :office
Yet when I test the association between account and partnership with an account that has hotels with partnerships (@account.partnerships), I get an empty [], whereas when I directly use the relevant hotel(@hotel.partnerships), I get my list of relevant partnerships. Could you tell me why these associations dont work : has_many :partnerships, through: :hotels, dependent: :destroy has_many :partnerships, through: :offices, dependent: :destroy

| Load UI in batches Posted: 24 May 2016 03:53 AM PDT I have a long FORM that has lots of fields(as fields can be dynamically created and I can't restrict the number of fields). When I edit form that has less than 20 fields, then the form loads properly. But, it starts getting delayed as the number of fields keeps increasing. I tried the following to batch load the FORM: #Inside edit.html.haml :javascript load_next_questions_set("#{url}", "#{params}", #{total_pages}, #{current_page}); #Inside app.js function load_next_questions_set(url, params, total_pages, current_page) { if(current_page <= total_pages) { var next_page = current_page + 1; jQuery.ajax({ url: url data: params, success: function(data) { jQuery("#some_div").append(data); setTimeout(function() { load_next_questions_set( jQuery.extend({url: url, total_pages: total_pages, current_page: current_page}, params) ); }, 2000); } }); } }
My moto is to load the form in the background without the knowledge of user. The problem is, until the entire form is loaded, the page becomes sluggish. How can I optimize this? And How can I avoid memory leaks? (if any). Or is there any better way to achieve this in Rails level? |

| Ability for users to add images to comments in Rails forum Posted: 24 May 2016 03:27 AM PDT So i have added the ability for users to add images to posts in my rails forum. I now want users to be able to add images to comments to posts. I began with a migration add_attachment_image_to_comments.rb class AddAttachmentImageToComments < ActiveRecord::Migration def self.up change_table :comments do |t| t.attachment :image end end def self.down remove_attachment :comments, :image end end
Edited the view file: = simple_form_for([@post, @post.comments.build]) do |f| = f.input :comment = f.input :image %br = f.submit
Here is the posts_controller file: class PostsController < ApplicationController before_action :find_post, only: [:show, :edit, :update, :destroy] before_action :authenticate_user!, except: [:index, :show] def index @posts = Post.all.order("created_at DESC").paginate(page: params[:page], per_page: 7) end def show end def new @post = current_user.posts.build end def create @post = current_user.posts.build(post_params) if @post.save redirect_to @post else render 'new' end end def edit end def update if @post.update(post_params) redirect_to @post else render 'edit' end end def destroy @post.destroy redirect_to root_path end private def find_post @post = Post.find(params[:id]) end def post_params params.require(:post).permit(:title, :content, :image) end
end Here is the comments_controller file: class CommentsController < ApplicationController def create @post = Post.find(params[:post_id]) @comment = @post.comments.create(params[:comment].permit(:comment, :image)) @comment.user_id = current_user.id if current_user @comment.save if @comment.save redirect_to post_path(@post) else render 'new' end end def edit @post = Post.find(params[:post_id]) @comment = @post.comments.find(params[:id]) end def update @post = Post.find(params[:post_id]) @comment = @post.comments.find(params[:id]) if @comment.update(params[:comment].permit(:comment, :image)) redirect_to post_path(@post) else render 'edit' end end def destroy @post = Post.find(params[:post_id]) @comment = @post.comments.find(params[:id]) @comment.destroy redirect_to post_path(@post) end end
This give users the ability to add the attachment. The problem i have now is getting the image to show in the comments section on the post. This is my show file: #post_content %h1= @post.title %p= @post.content = image_tag @post.image.url(:medium) #comments %h2 = @post.comments.count Comment(s) = render @post.comments = image_tag @comment.image.url(:medium)
I get the error - undefined method `image' for nil:NilClass. Highlighing this row - = image_tag @comment.image.url(:medium) Any help much appreciated. |
| rspec rails testing session_id Posted: 24 May 2016 03:35 AM PDT I have a quite peculiar thing to test. Recently we have changed from cookie-storage to active-record-storage when it comes to storing session information. This was done in order to prevent using session_id from cookies to continue browsing session even after users was logged out (That's a thing you need to sadly accept when using cookie-storage). Now I need to write some code to test whether moving to active-record-storage indeed fixed that security issue but I dont know how. The scenario is that: user signs in to the app users signs out of the app session_id from the request header is then used in get request to view a part of the app that normally needs authentication this should not be possible, because we are not authenticated(although we use the session_id from the previous request)
we get a 401, or 404 or anything else than 200 hopefully. So far I have managed to get the session_id from the request -> @request.env["rack.sesion.options"][:id] but I don't know how to use and put this session_id into next request any ideas? |
