  • Can using Chronic impair you sense of time?

    - by Trip
    Haha.. I'm using Chronic to parse the time users add in the Calendar. Where the code works and implements the right time, the end result is that, IF a user adds a time, then it has no date, and because it has no date, it will not show in results. Any ideas? def set_dates unless self.natural_date.blank? || Chronic.parse(self.natural_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_date) self.date = nil self.time = Chronic.parse(self.natural_date) else self.date = Chronic.parse(self.natural_date).to_date self.time = nil end end unless self.natural_end_date.blank? || Chronic.parse(self.natural_end_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_end_date) self.end_date = nil self.end_time = Chronic.parse(self.natural_end_date) else self.end_date = Chronic.parse(self.natural_end_date).to_date self.end_time = nil end end end

  • How to get notified of changes on a read only table? (I.e., Price drop notifications.)

    - by mirthlab
    Let's say I have these tables/models: Product - id - last_updated_date - name - price User - id - name Wishlist - id - user_id - product_id The Product table has a few million records and is being updated automatically each night via a data import (inserting into a new table, dropping the old one). I basically have read-only access to that table/model. If a product is on a user's wishlist and the price drops, I'd like to be able to notify that user. What methods can be used to do this? I have a couple of ideas: Keep track of the Product.last_updated_date in the wishlist model and periodically poll the product table to see if it has been updated. This sounds like a horrible/non-scaleable solution. Some sort of Postgres View or Function that triggers when the Product table is updated? I'm new to postgres so I'm not yet sure if this is even possible. Something amazing that you will suggest that I haven't thought of :) Any help in the right direction is greatly appreciated!

  • Saving an ActiveRecord non-transactionally.

    - by theFunkyEngineer
    My application accepts file uploads, with some metadata being stored in the DB, and the file itself on the file system. I am trying to make the metadata visible in the application before the file upload and post-processing are finished, but because saves are transactional, I have had no success. I have tried the callbacks and calling create_or_update() instead of save(), all to no avail. Is there a way to do this without re-writing the guts of ActiveRecord::Base? I've even attempted naming the method make() instead of save(), but perplexingly that had no effect. The code below "works" fine, but the database is not modified until everything else is finished. def save(upload) uploadFile = upload['datafile'] originalName = uploadFile.original_filename self.fileType = File.extname(originalName) create_or_update() # write the file File.open(self.filePath, "wb") { |f| f.write(uploadFile.read) } begin musicFile = TagLib::File.new(self.filePath()) self.id3Title = musicFile.title self.id3Artist = musicFile.artist self.id3Length = musicFile.length rescue TagLib::BadFile => exc logger.error("Failed to id track: \n #{exc}") end if(self.fileType == '.mp3') convertToOGG(); end create_or_update() end Any ideas would be quite welcome, thanks.

  • How can I add two models in one form, where one model is a has_many :through?

    - by Angela
    How do I model having multiple Addresses for a Company and assign a single Address to a Contact? Contacts belong_to a Company. A Company has_many Contacts. A Company also has_many Addresses. And each Contact has_one Address. I want to be able, whenever I create a New Contact, to access all the addresses in all Contacts that belong to the Company. Here is are my Models: class Company < ActiveRecord::Base attr_accessible :name, :phone, :addresses has_many :contacts has_many :addresses, :through => :contacts end class Contact < ActiveRecord::Base attr_accessible :first_name, :last_name, :title, :phone, :fax, :email, :company, :date_entered, :campaign_id, :company_name, :address belongs_to :company has_one :address accepts_nested_attributes_for :address end class Address < ActiveRecord::Base attr_accessible :street1 has_many :contacts end How do I create the View in the _form for Contacts so that I can 1) Add an Address when creating a Contact; 2) Display the options of the Address. Here is how I am doing step 1, which is just to add a new address for a new contact: <% f.fields_for :addresses do |builder| %> <p> <%= builder.label :street1, "Street 1" %> </br> <%= builder.text_field :street1 %> <p> Right now, what I have doesn't work. The console says I cannot mass-assign addresses when I hit "submit" on this New contact form.

  • How do I create a polymorphic model with a collection_select?

    - by muxe
    This are my models: class Speaker < ActiveRecord::Base belongs_to :session, :foreign_key => :session_id, :class_name => :Session belongs_to :speakable, :polymorphic => true end class Session < ActiveRecord::Base has_many :speakers accepts_nested_attributes_for :speakers end class Person < ActiveRecord::Base has_many :speakers, :as => :speakable end class Company < ActiveRecord::Base has_many :speakers, :as => :speakable end What I want to do now is something like this: app/views/sessions/edit.html.erb <% f.fields_for :speakers do |sf| %> <p> <%= sf.label :speaker %><br /> <%= sf.collection_select :speakable, Company.all + Person.all, :id, :full_name %> </p> <% end %> But it is not working because of the polymorphic assignment. How do I approach this problem? EDIT: The Error is: undefined method `base_class' for String:Class with params being: "speaker"=>{"speakable"=>"1063885469", "session_id"=>"1007692731"} The value passed to speakable is the id of the Speaker/Company. Yes, this is the value I specified the collection_select to return, but how can I manage to supply both values (speakable_id and speakable_type) ?

  • Unique view count.

    - by alokswain
    I have a collection of links which are being displayed on the index page. Whenever a user clicks a link I want to keep a track of the number of unique views. I know it can be done by tracking the ips whenever a click happens by request.remote_ip and then the link of the page that was clicked. Is there any better approach ? Any plugins etc.

  • How to stub Restul-authentication's current_user method?

    - by Thiago
    Hi there, I'm trying to run the following spec: describe UsersController, "GET friends" do it "should call current_user.friends" do user = mock_model(User) user.should_receive(:friends) UsersController.stub!(:current_user).and_return(user) get :friends end end My controller looks like this def friends @friends = current_user.friends respond_to do |format| format.html end end The problem is that I cannot stub the current_user method, as when I run the test, I get: Spec::Mocks::MockExpectationError in 'UsersController GET friends should call current _user.friends' Mock "User_1001" expected :friends with (any args) once, but received it 0 times[0m ./spec/controllers/users_controller_spec.rb:44: current_user is a method from Restful-authentication, which is included in this controller. How am I supposed to test this controller? Thanks in advance

    - by Justin Meltzer
    I want to turn two "voting" links into jQuery UI icons. One is the upvote link that should be an icon with an up arrow, and one is the downvote link that should be an icon with a down arrow. Here is one of the link's RoR code: <%= link_to "+1", video_votes_path( :video_id => video.id, :type => "up" ), :method => :post, :remote => true %> I also want to change the color of the icon when it is clicked, and when it is clicked again, it should change back to its original color. How can I do all of this?

  • form_for [@parent,@son],:remote=>true not asking for JS

    - by Cibernox
    Hi. I have a plain old form. That form is used to create new objects of a nested model. #restaurant.rb has_many :courses #courses.rb belongs_to :restaurant #routes.rb resources :restaurants do resources :courses end In my views(in haml), i have that code: %li.course{'data-random'=>random} = form_for([restaurant,course], :remote=>true) do |f| .name= f.text_field :name, :placeholder=>'Name here' .cat= f.hidden_field :category .price= f.text_field :price,:placeholder=>'Price here' .save = hidden_field_tag :random,random = f.submit "Save" I espected that form to be answered by action create of courses_controller with JS (create.js.erb), but it is submited like a normal form, and is answered with html. What am I doing wrong? This problem is similar to this but the only answer don't make sense to me. Thanks Inside

  • How to add or remove a value inside a table cell on selection / de-selection of checkbox of that row, trying to submit the value via Jquery?

    - by Raul
    Here is the table: <%= form_tag '', :id => "costs" do %> <table class="table table-bordered" id="service_cost"> <% @services.each do |service| %> <tbody> <tr> <td><%= check_box_tag :open_service, {}, false, :class => 'checkable' %></td> <td><%= service.phone %></td> <td><%= service.internet %></td> <td></td> <td></td> <td></td> <td></td> <td></td> <td><%= service.house_keeping %> </td> <td>0.0 </td> <td><%= service.laundry %></td> <td><%= text_field_tag "service_cost", service.total, :class => "input-small" %></td> </tr> <% end %> when the form gets submitted, the javascript gets into action: $("#costs").submit(function(){ formData=$("#costs").serializeArray(); processFormData(formData) return false; }); This ensures form submission on selecting the checkbox: $('.checkable').live('change', function() { $(this).parents('form:first').submit(); }); But, what I am looking for is adding or removing a cell value based on checkbox selection/de-selection and submitting it, kindly suggest a way to do it.

  • how rspec creates database between specs

    - by timpone
    This is a bit of a naive / simple question. I'm having a hard time finding this info online. Basically, does rspec run rake db:test:prepare between every rspec group? Or is it between every example or model? Or does the schema get loaded once and then truncated between each. I need to add a rake task directly after this call to create a view since they are not supported in schema.rb. Either a link or explanation would be greatly appreciated so that I know where to insert my rake task to create a view. Or whether there is a callback like rake db:test:after_prepare thx

  • How to copy a file using Paperclip

    - by CalebHC
    Does anyone know of a way to copy files with Paperclip using S3 for storage? Before I try to write my own, I just wanted to make sure there wasn't already a way to do this. Speaking of copying, is there an easier way of copying a whole model including all of its has_many relationships? Sorry for the second question but it kind of fits! :) Thanks
