  • Rails 3 query in multiple date ranges

    - by NeoRiddle
    Suppose we have some date ranges, for example: ranges = [ [(12.months.ago)..(8.months.ago)], [(7.months.ago)..(6.months.ago)], [(5.months.ago)..(4.months.ago)], [(3.months.ago)..(2.months.ago)], [(1.month.ago)..(15.days.ago)] ] and a Post model with :created_at attribute. I want to find posts where created_at value is in this range, so the goal is to create a query like: SELECT * FROM posts WHERE created_at BETWEEN '2011-04-06' AND '2011-08-06' OR BETWEEN '2011-09-06' AND '2011-10-06' OR BETWEEN '2011-11-06' AND '2011-12-06' OR BETWEEN '2012-01-06' AND '2012-02-06' OR BETWEEN '2012-02-06' AND '2012-03-23'; If you have only one range like this: range = (12.months.ago)..(8.months.ago) we can do this query: Post.where(:created_at => range) and query should be: SELECT * FROM posts WHERE created_at BETWEEN '2011-04-06' AND '2011-08-06'; Is there a way to make this query using a notation like this Post.where(:created_at => range)? And what is the correct way to build this query? Thank you

  • Rails - Format number as currency format in the Getter

    - by daemonsy
    I am making a simple retail commerce solution, where there are prices in a few different models. These prices contribute to a total price. Imagine paying $0.30 more for selecting a topping for your yogurt. When I set the price field to t.decimal :price, precision:8, scale:2 The database stores 6.50 as 6.5. I know in the standard rails way, you call number_to_currency(price) to get the formatted value in the Views. I need to programmatically call the price field as well formatted string, i.e. $6.50 a few places that are not directly part of the View. Also, my needs are simple (no currency conversion etc), I prefer to have the price formatted universally in the model without repeated calling number_to_currency in views. Is there a good way I can modify my getter for price such that it always returns two decimal place with a dollar sign, i.e. $6.50 when it's called? Thanks in advance.

  • Accessing an API

    - by Paritosh Praharaj
    I'm trying to build a Rails app where I have to access the Zomato API Could anybody guide me on how to create the Controller and View. Suppose I want to get the name of the restaurant from this URL: Restaurant, how do I write the controller and views for it. Currently, I'm using HTTParty gem. This is my controller code: def restaurants @response = HTTParty.get("https://api.zomato.com/v1/restaurant.json/773", :headers => {"X-Zomato-API-Key" => "MYAPIKEY"}) puts response.body, response.code, response.message, response.headers.inspect @categories = Category.where(:category_name => 'Restaurants') end And I'm trying to get the response object in the view: <%= @response.each do |item| %> <td><%= item.id %></td> <td><%= item.name %></td> <td><%= item.url %></td> <% end %> So, this shows the following error: undefined method 'id' for ["id", 773]:Array

  • named_scope + average is causing the table to be specified more then once in the sql query run on po

    - by hadees
    I have a named scopes like so... named_scope :gender, lambda { |gender| { :joins => {:survey_session => :profile }, :conditions => { :survey_sessions => { :profiles => { :gender => gender } } } } } and when I call it everything works fine. I also have this average method I call... Answer.average(:rating, :include => {:survey_session => :profile}, :group => "profiles.career") which also works fine if I call it like that. However if I were to call it like so... Answer.gender('m').average(:rating, :include => {:survey_session => :profile}, :group => "profiles.career") I get... ActiveRecord::StatementInvalid: PGError: ERROR: table name "profiles" specified more than once : SELECT avg("answers".rating) AS avg_rating, profiles.career AS profiles_career FROM "answers" LEFT OUTER JOIN "survey_sessions" survey_sessions_answers ON "survey_sessions_answers".id = "answers".survey_session_id LEFT OUTER JOIN "profiles" ON "profiles".id = "survey_sessions_answers".profile_id INNER JOIN "survey_sessions" ON "survey_sessions".id = "answers".survey_session_id INNER JOIN "profiles" ON "profiles".id = "survey_sessions".profile_id WHERE ("profiles"."gender" = E'm') GROUP BY profiles.career Which is a little hard to read but says I'm including the table profiles twice. If I were to just remove the include from average it works but it isn't really practical because average is actually being called inside a method which gets passed the scoped. So there is some times gender or average might get called with out each other and if either was missing the profile include it wouldn't work. So either I need to know how to fix this apparent bug in Rails or figure out a way to know what scopes were applied to a ActiveRecord::NamedScope::Scope object so that I could check to see if they have been applied and if not add the include for average.

  • Is there a way to validates_presence_of only one time? (to skip that validation once the user's been

    - by GoodGets
    So, I'd like for a user to see an error message if he submits a comment and the :name is blank (typical error message, don't need help with that). However, I'd then like to allow the user to skip that validation once he's been notified that "we like all comments to have a name." So, he submits the comment once, sees the notification, then can submit the form again unchanged if he really doesn't want to add a name, and the validates_presences_of :name is skipped. But, I'm not sure how to go about doing this. I thought about checking to see where the request is coming from, but after a create, errors are handed off to the "new" action, which is the same as actual "new" comments. I then thought about checking to see if flash[errors] were present, but that won't work because there are other validations a comment has to pass. Finally, I thought about trying a validates_presences_of :name, :unless = :notified but wasn't sure how to define notified. I honestly hate asking such an open ended question, but wasn't sure where to get started. So, is there a way to just check a certain validation once?

  • Workling processes multiplying uncontrolably

    - by adam
    Hello there. We have a rails app running on passenger and we background process some tasks using a combination of RabbitMQ and Workling. The workling's worker process is started using the script/workling_client command. There is always only one worker process started, and the script/workling_client has a :multiple => false options, thus allowing only one instance. But sometimes, under mysterious circumstances which I haven't been able to track down, more worklings spawn up. If I let the system run for some time, more and more worklings appear. I'm not sure if these rogue worklings cause any problems, but it is still unsettling not to know why is it happening. We are using Monit to monitor the workling process. So if it dies, it will spawn it up again. But this still does not explain how come there are suddenly more than one of them. So my question is: does anyone know what can be cause of this and how to make it stop? Is it possible that workling sometimes dies by itself, without deleting it's pid file? Could there be something wrong with the Daemons gem workling_client is build upon?

  • Polymorphic :has_many, :through as module in Rails 3.1 plugin

    - by JohnMetta
    I've search everywhere for a pointer to this, but can't find one. Basically, I want to do what everyone else wants to do when they create a polymorphic relationship in a :has_many, :through way… but I want to do it in a module. I keep getting stuck and think I must be overlooking something simple. To wit: module ActsPermissive module PermissiveUser def self.included(base) base.extend ClassMethods end module ClassMethods def acts_permissive has_many :ownables has_many :owned_circles, :through => :ownables end end end class PermissiveCircle < ActiveRecord::Base belongs_to :ownable, :polymorphic => true end end With a migration that looks like this: create_table :permissive_circles do |t| t.string :ownable_type t.integer :ownable_id t.timestamps end The idea, of course, is that whatever loads acts_permissive will be able to have a list of circles that it owns. For simple tests, I have it "should have a list of circles" do user = Factory :user user.owned_circles.should be_an_instance_of Array end which fails with: Failure/Error: @user.circles.should be_an_instance_of Array NameError: uninitialized constant User::Ownable I've tried: using :class_name => 'ActsPermissive::PermissiveCircle' on the has_many :ownables line, which fails with: Failure/Error: @user.circles.should be_an_instance_of Array ActiveRecord::HasManyThroughSourceAssociationNotFoundError: Could not find the source association(s) :owned_circle or :owned_circles in model ActsPermissive::PermissiveCircle. Try 'has_many :owned_circles, :through => :ownables, :source => <name>'. Is it one of :ownable? while following the suggestion and setting :source => :ownable fails with Failure/Error: @user.circles.should be_an_instance_of Array ActiveRecord::HasManyThroughAssociationPolymorphicSourceError: Cannot have a has_many :through association 'User#owned_circles' on the polymorphic object 'Ownable#ownable' Which seems to suggest that doing things with a non-polymorphic-through is necessary. So I added a circle_owner class similar to the setup here: module ActsPermissive class CircleOwner < ActiveRecord::Base belongs_to :permissive_circle belongs_to :ownable, :polymorphic => true end module PermissiveUser def self.included(base) base.extend ClassMethods end module ClassMethods def acts_permissive has_many :circle_owners, :as => :ownable has_many :circles, :through => :circle_owners, :source => :ownable, :class_name => 'ActsPermissive::PermissiveCircle' end end class PermissiveCircle < ActiveRecord::Base has_many :circle_owners end end With a migration: create_table :permissive_circles do |t| t.string :name t.string :guid t.timestamps end create_table :circle_owner do |t| t.string :ownable_type t.string :ownable_id t.integer :permissive_circle_id end which still fails with: Failure/Error: @user.circles.should be_an_instance_of Array NameError: uninitialized constant User::CircleOwner Which brings us back to the beginning. How can I do what seems to be a rather common polymorphic :has_many, :through on a module? Alternatively, is there a good way to allow an object to be collected by arbitrary objects in a similar way that will work with a module?

  • Can 'locals' be used with 'collection' when rendering partials in Rails?

    - by Gav
    Everything works okay when I try to render a partial like this: = render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types However, if I also want to pass a variable (in this case 'path', because I'm sharing this partial across two forms), the path is not available to me: = render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types, :locals => {:path => customers_enquiry_path} I've tried moving things around, but nothing appears to work, leading me to believe one cannot use locals with collections. Any help would be appreciated. Gav

  • Rails: common approach for handling exceptions in restful actions on objects that have been destroye

    - by Greg
    It is very common in Rails for an objects_controller controller to have RESTful edit and destroy actions like so: def edit @object = Object.find(params[:id]) end def destroy @object = Object.find(params[:id]) @object.destroy redirect_to :back end With an associated view that provides edit and destroy links like so: <%= link_to "Edit the Object", edit_object_path(object) %> <%= link_to "Delete", object, :confirm => 'Are you sure?', :method => :delete %> And it is easy to blow this up. If I open two browser windows, A and B, destroy an object with the "Delete" link in browser A and then press the "Edit" link in browser B, the find() in the edit action throws an exception. Obviously there are several ways to deal with this in the edit action: catch the exception and recover gracefully use @object = find(:first, "conditions... etc. and test the @object before going further But seeing as this is such a common pattern, I would love to know how other folks deal with this situation.

  • Rails method as a nested resource

    Hello, I'm wondering about the clever way to do this... I have methods that return a value when passed an an object as parameter, such as: <%= average_rainfall(@location) % I'd like to use the exact same methods as a nested resource to call via jQuery/Ajax, like so: .load('/location/8/average_rainfall') I understand how to define the route, but how do I tell my method to 'find' /location/8 and use that as it's parameter instead of @location as expected? Thanks!

  • Rails messing up with HTTP POST Params

  • Rails - default value in text_field but only for new_record?

    - by jyoseph
    On a Content model have an attribute named slug. When creating a new record, I want to use a helper to populate this field, but on an existing record I want to use the value from the database. Currently I have: <%- if @content.new_record? -%> <%= f.text_field :slug, :value => "#{generate_slug(6)}" %> <%- else %> <%= f.text_field :slug %> <%- end %> But that seems a bit verbose. Is this the best way, or is there no other way? (Rails newb just trying to find the "Rails way" on issues I'm unsure of) Edit I should note that the helper is currently in /app/helpers/application_helper.rb

  • Dynamic select menu Rails, Javascript HABTM

    - by Jack
    Hi, I am following a tutorial in one of Ryan Bates' Railscasts here. Basically I want a form where there are 2 drop down menus, the contents of one are dependent on the other. I have Years and Courses, where Years HABMT Courses and Courses HABTM Years. In the tutorial, the javascript is as follows: var states = new Array(); <% for state in @states -%> states.push(new Array(<%= state.country_id %>, '<%=h state.name %>', <%= state.id %>)); <% end -%> function countrySelected() { country_id = $('person_country_id').getValue(); options = $('person_state_id').options; options.length = 1; states.each(function(state) { if (state[0] == country_id) { options[options.length] = new Option(state[1], state[2]); } }); if (options.length == 1) { $('state_field').hide(); } else { $('state_field').show(); } } document.observe('dom:loaded', function() { countrySelected(); $('person_country_id').observe('change', countrySelected); }); Where I guess country has many states and state belongs to country. I think what I need to do is edit the first for statement to somehow loop through all of the courses for each year_id, but don't know how to do this. Any ideas? Thanks

  • Get ANSI-colored output from external command

    - by German Rumm
    I am writing a small script for watchr that runs my PHP unit tests. Current script runs tests using system() and displays them colored. I am trying to add libnotify functionality, but for that I need to parse the output and match against regexp, so that notification will either display green or red. system() doesn't return output, %x does return, but puts p doesn't display colors, which I need to quickly see which test failed. One option would be to run tests twice - once for display in terminal window, and second time for checking which notification to show, but I would rather avoid it.

  • Unit Testing a rails 2.3.5 plugin

    - by brad
    I'm writing a new plugin for a rails 2.3.5 app. I've included an app directory (which makes it an engine) so i can easily load some extra routes. Not sure if that affects anything. Anyway, in the test directory i have two files: test_helper.rb and my_plugin_test.rb These files were generated automatically using script/generate plugin my_plugin When I go to vendor/plugins/my_plugin directory and run rake test they don't seem to run. I get the following console output: (in /Users/me/Repos/my_app/source/trunk/vendor/plugins/my_plugin) /Users/me/.rvm/rubies/jruby-1.4.0/bin/jruby -I"lib:lib:test" "/Users/me/.rvm/gems/jruby-1.4.0/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" "test/my_plugin_test.rb" So it obviously sees my test file, but none of the tests inside get run, I just get back to my console prompt. What am I missing here? I figured the generated code would work out of the box Here are the two files test_helper.rb require 'rubygems' require 'active_support' require 'active_support/test_case' my_plugin_test.rb require 'test_helper' class MyPluginTest < ActiveSupport::TestCase # Replace this with your real tests. test "the truth" do assert true end test "Factories are supported" do assert_not_nil Factory end end File structure vendor - plugins - my_plugin - app - config - routes.rb - generators - my_plugin - some generator files.rb - lib - my_plugin.rb - my_plugin - my_plugin_lib_file.rb - rails - init.rb - Rakefile - tasks - my_plugin_tasks.rake - test - test_helper.rb - my_plugin_test.rb

  • Rails Multiple Table Inheritance question

    - by Tony
    I am starting to implement an MTI solution and have a basic question. I have 3 physical models - SMSNotifications, EmailNotifications, TwitterNotifications and they are subclasses of notification. At times in my code, I want to say Notifications.find(:all)so that I can get a set of results sorted by their creation time. Then I want to do things based on their subclass. What is the way to write Notifications.find(:all) and have Rails look through the subclass tables and combine the results? Right now Rails still thinks I have a physical Notifications table which goes against my MTI design. I am also considering the possibility that I should be using STI instead. I would probably have 10 empty columns per row but if getting all notifications requires a query for each type of notification, then I feel like this could be a big issue. Thanks!

  • Cucumber vs. built-in testing? [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 Cucumber? 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.

  • Apache/Rails/Passenger directory URLs that don't end in '/' fail to 404.

    - by Portamento
    I'm using Apache with passenger to run a rails app. In my rails app, I have some static content in subdirectories of the public directory. Each subdirectory has an index.html in it. So, inside the public directory, I have a subdir called 'b' and inside it, is an index.html. So it's like this: /public/b/index.html I have links to these pages, of the form: http://a.com/b If I do this in my regular non-rails web directory, Apache correctly rewrites this URL to be http://a.com/b/ which then, subsequently shows the index.html. It's only when accessing my rails app that it doesn't work. In fact, if I turn off passenger mod... so it just accesses my rails app like a regular document root, it works correctly also. What the heck do I need to do to get this to work properly with passenger? Again, it works fine in apache itself when passenger is not involved. I am running passenger 2.1.3. I have another server running passenger 2.0 that doesn't seem to have this problem, but I don't see anything different in the config other than the different versions of passenger itself. HELP! Been working on this for two days solid with no improvement!
