  • How do I use a named_scope to filter records in my model

    - by kibyegon
    I have a model "Product" with a "description" field. Now I want to have a link in the index page that when clicked will show all products where the description is blank (empty). In the model I have defined a named_scope like this named_scope :no_description, :conditions => { :description => "" } I have checked that the named_scope works by calling Product.no_description.count on the console. As far as I know, the controller is then supposed to handle the filter request from the link on the "index" action but be able to distinguish it from the default which is view all products. def index @products = Product.all ... My problem is getting the controller handle the different request, what route to setup for the link on the view and the actual link on the view. Hope I explained my problem.

  • How to clone a model's attributes easily?

    - by Zabba
    I have these models: class Address < ActiveRecord::Base belongs_to :event attr_accessible :street, :city validates :street, :city, :presence => true end class Event < ActiveRecord::Base has_one :address accepts_nested_attributes_for :address end If I do the below assignment in the Events create action and save the event I get an error: #Use the current user's address for the event @event.address_attributes = current_user.address.attributes #Error occurs at the above mentioned line ActiveRecord::RecordNotFound (Couldn't find Address with ID=1 for Event with ID=) I think what's happening is that all the address's attributes (including the primary key) is getting assigned in the @event.address_attributes = line. But all I really want is the "real data" (street, city), not the primary keys or created_at etc to get copied over. I suppose I could write a small method to do this sort of selective copy but I can't help but feel there must be some built-in method for this? What's the best/right way to do this?

  • Retrieving Data From formData in Rails jquery-file-upload

    - by CanCeylan
    I am trying to add additional form data by using https://github.com/blueimp/jQuery-File-Upload/wiki/How-to-submit-additional-form-data this tutorial for jQuery-File-Upload plugin in my Rails app. I'm following the instructions for Setting formData on upload start for each individual file upload. My problem is, after saving the files with their titles as explained in tutorial, I cannot show them in the final table, because I don't know how to reach the formData's values. How should I reach the data inside data.formData = inputs.serializeArray(); and post them next to each item ? Thanks.

  • Rails attribute alias

    - by Dr1Ku
    Hi, I was just wondering if it's possible to "rename" an association in Rails. Let's assume : # An ActiveRecord Class named SomeModelASubModel (some_model_a_sub_model.rb) class SomeModelASubModel < ActiveRecord::Base has_many :some_model_a_sub_model_items end # An ActiveRecord Class named SomeModelASubModelItem (some_model_a_sub_model_item.rb) class SomeModelASubModelItem < ActiveRecord::Base belongs_to :some_model_a_sub_model end At this point, calling some_model.items, where some_model is an instance of the SomeModelASubModel Class would trigger an undefined method error. What is the best practice for making this happen though, e.g. : # With a method_alias or something, would it be possible to : some_model = SomeModelASubModel.first # for instance items = some_model.items # For the reason stated, this doesn't work, one has to call : items = some_model.some_model_a_sub_model_items Is such a shorthand possible ? Thank you in advance !

  • for TimeWithZone object, how to change the zone part only?

    - by leomayleomay
    I have a table Coupon with a field expired_at, which is of datetime type, and before I save the record, I want to change the zone part of the field according to the user's choice. Say, c = Coupon.new c.expired_at = DateTime.now c.expired_at_timezone = "Arizona" c.save! and in the coupon.rb class Coupon << ActiveRecord::Base def before_save # change the zone part here, leave the date and time part alone end end What I'm saying is if the admin want the coupon expired at 2014-07-01 10:00 am, Arizona time, the expired_at stored in the db should be like this: Tue, 01 Jul 2014 10:00:00 MST -07:00 is there any way I can modify the zone part only and leave the date and time part alone? Thanks

  • Build model with nested model in rspec integration test

    - by user1116573
    I understand that I can do something like in rspec: let(:project) { Project.new } but in my app a project accepts_nested_attributes_for tasks and when I generate the Project form I build a task along with it using: @project = Project.new @project.tasks.build I need something like: let(:project) { Project.new.tasks.build } but that doesn't seem to work. How can I do this as a let in my rspec test?

  • update_attributes with validations

    - by Timothy
    I have the following contrived example in Rails. I want to make sure the Garage model has at least one car with this. class Garage has_many :cars validate :at_least_one_car def at_least_one_car if cars.count == 0 errors.add_to_base("needs at least one car") end end end class Car belongs_to :garage end In my form I have a remove button that will set the hidden field _delete to true for an existing car. Let's say there is only one car object and I "delete" it in my form, if I do garage_object.update_attributes(params[:garage]), it will delete the car model and make the garage object invalid. Is there to a way to make it not update the attributes if it will make the model invalid?

  • Rails: bi-directional has_many :through relationship

    - by Chris
    I have three models in a Rails application: Game represents an instance of a game being played. Player represents an instance of a participant in a game. User represents a registered person who can participate in games. Each Game can have many Players, and each User can have many Players (a single person can participate in multiple games at once); but each Player is in precisely one Game, and represents precisely one User. Hence, my relationships are as follows at present. class Game has_many :players end class User has_many :players end class Player belongs_to :game belongs_to :user end ... where naturally the players table has game_id and user_id columns, but games and users have no foreign keys. I would also like to represent the fact that each Game has many Users playing in it; and each User has many Games in which they are playing. How do I do this? Is it enough to add class Game has_many :users, :through => :players end class User has_many :games, :through => :players end

  • simple search in rails

    - by Adnan
    Hi, I'm making a simple search form in rails. In my search view I have two select boxes with fixed values like: SELECT BOX 1 SELECT BOX 2 ALL, ALL, FR, FR, US, US, DE DE And I have 2 fields in my DB with country_from and country_to. So for making a simple search like from FR to US I use: @search_result = Load.find(:all, :conditions => "country_from='#{params[:country_from]}' AND country_to='#{params[:country_to]}'" ) that is fine, but I need to implement the ALL option as well, so when I make a search like from DE to ALL I get a list with all countries in country_to I image I can do it with ifs...but what would be the most efficient way to do it?

  • What to use to write tests? [Rails]

    - by yuval
    I asked a question about different testing frameworks yesterday. This question can be found here. Now that I have a better understanding of the different frameworks, I have a very simple question: With a basic understanding, but very limited experience with writing tests with rails' built in testing framework (basic assertions), would it be okay for me to jump directly to testing with RSpec, Webrat, and Cucamber? Thank you! As a side note: yes, this is an opinion based question, but I feel that the input received to this question is valuable enough to the community to keep this question open. Thanks.

  • Find and sort by number of ocurrences of tag with Active Admin and act_as_taggable_on

    - by nunopolonia
    I'm using act_as_taggable_on and Active Admin on a Rails project. In that project there are Posts and each Post has Tags. I want to show a list of Tags in Active Admin and the number of ocurrences of each one. The way I found to do this was: index do column :name column :ocurrences do |tag| ocurrences = Post.tag_counts.find(tag.id).count end default_actions end Which will search the Tag List every time for every Post, which performance wise looks really bad. I would also like to be able to sort the tags by ocurrence. Any idea of how I can do it?

  • Field name being converted in Unit Tests [rails]?

    - by yar
    I am noting this strange behavior where one of my fields -- receive_empresa_test_info -- has worked fine though it's always been referred to as receive_empresa_info. In Functional Tests, though, the real field name is receive_empresa_test_info. What is going on here? Might this be some part of the Rails environment that I'm missing during testing?

  • Rails - Create if record doesn't exist or else update.....Whats Best way to do this?

    - by ChrisWesAllen
    Hi, I have a create statement for some models but its creating a record within a join table regardless if the record exist. Here is what my code looks like. @user = User.find(current_user) @event = Event.find(params[:id]) for interest in @event.interests @user.choices.create(:interest => interest, :score => 4) end The problem is it creates records no matter what. I would like it to create a record if it doesnt exist, if a record does exist I would just to it to take the attribute of the found record and add or subtract 1. So, I've been looking around and I see something called find_or_create_by. My question is what happens if it finds? Preferably if it finds,I would like to take the current :score attribute and +1. SO is it possible to find or create by id? I'm not sure what attribute I would find by since the model I'm looking at is a join model which only had id foreign keys and the score attribute. I tried @user.choices.find_or_create_by_user(:user => @user.id, :interest => interest, :score => 4) but got "undefined method `find_by_user'".....ANy ideas or help?

  • scope equivalent in rails 2.3.x?

    - by Jacob Relkin
    Is there a way to generate a group of routes under an admin scope without having to create a new physical directory (like namespace requires you to). I know that in Rails 3 there is a scope method on the route mapper, and this appears to do what I want, but apparently it doesn't exist in Rails 2.3.x My goal is to have a route like this: "/admin/products" map to "app/controllers/products_controller, not "app/controllers/admin/products_controller". Is there any way to accomplish this in Rails 2.3.x?

  • Building a calendar navigation in Rails (controller and view links)

    - by user532339
    Trying to get the next month when clicking the link_to. I've done the following in the view. <%= form_tag rota_days_path, :method => 'get' do %> <p> <%= hidden_field_tag(:next_month, @t1) %> <%= link_to 'Next Month', rota_days_path(:next_month => @next_month)%> </p> <% end %> class RotaDaysController < ApplicationController # GET /rota_days # GET /rota_days.json # load_and_authorize_resource respond_to :json, :html def index @rota_days = RotaDay.all @hospitals = Hospital.all @t1 = Date.today.at_beginning_of_month @t2 = Date.today.end_of_month @dates = (@t1..@t2) #Concat variable t1 + t2 together # @next_month = Date.today + 1.month(params[: ??? ] #Old if params[:next_month] # @next_month = Date.today >> 1 @next_month = params[:next_month] + 1.month @t1 = @next_month.at_beginning_of_month @t2 = @next_month.end_of_month @dates = (@t1..@t2) end @title = "Rota" respond_to do |format| format.html # index.html.erb format.json { render json: @rota_days } end end I have identified that the reason why this may not be working is in because of the following in my controller @next_month = params[:next_month] + 1.month the last two called methods is defined only on time/date objects. but not on fixnum/string objects. I understand I am missing something from this Update I have found that the actual issue is that the `params[:next_month] is a string and I am trying to add a date to to it. Which means I need to convert the string to a date/time object. Console output: Started GET "/rota_days" for 127.0.0.1 at 2012-12-14 22:14:36 +0000 Processing by RotaDaysController#index as HTML User Load (0.0ms) SELECT `users`.* FROM `users` WHERE `users`.`id` = 1 LIMIT 1 RotaDay Load (0.0ms) SELECT `rota_days`.* FROM `rota_days` Hospital Load (1.0ms) SELECT `hospitals`.* FROM `hospitals` Rendered rota_days/index.html.erb within layouts/application (23.0ms) Role Load (0.0ms) SELECT `roles`.* FROM `roles` INNER JOIN `roles_users` ON `roles`.`id` = `roles_users`.`role_id` WHERE `roles_users`.`user_id` = 1 AND `roles`.`name` = 'Administrator' LIMIT 1 Completed 200 OK in 42ms (Views: 39.0ms | ActiveRecord: 1.0ms)

Its content is into the grid.html.haml and this file can only use the instance vars set in the grid_module.rb is this possible to do?

  • 1) PasswordResets emails user when requesting password reset

    - by Surge Pedroza
    I've been trying to add a password reset for users that forget their password. The users clicks on forgot password? on sign up page.
