  • Testing instance variables from controllers with rspec

    - by Thiago
    Hi, I am trying to get the following spec to run: describe BlacklistController, "GET index" do it "should display the list of universally blocked numbers" do get :index debugger assigns[:blocked_numbers].should contain "190" end end Here's the action def index @blocked_numbers << "190" respond_to do |format| format.html end end And the failure simply says that assigns[:blocked_numbers} is nil. Why's that?

  • counter_cache not updating on the model after save

    - by sehnsucht
    I am using a counter_cache to let MySQL do some of the bookkeeping for me: class Container has_many :items end class Item belongs_to :container, :counter_cache => true end Now, if I do this: container = Container.find(57) item = Item.new item.container = container item.save in the SQL log there will be an INSERT followed by something like: UPDATE `containers` SET `items_count` = COALESCE(`items_count`, 0) + 1 WHERE `containers`.`id` = 57 which is what I expected it to do. However, the container[:items_count] will be stale! ...unless I container.reload to pick up the updated value. Which in my mind sort of defeats part of the purpose of using the :counter_cache in favor of a custom built one, especially since I may not actually want a reload before I try to access the items_count attribute. (My models are pretty code-heavy because of the nature of the domain logic, so I sometimes have to save and create multiple things in one controller call.) I understand I can tinker with callbacks myself but this seems to me a fairly basic expectation of the simple feature. Again, if I have to write additional code to make it fully work, it might as well be easier to implement a custom counter. What am I doing/assuming wrong?

  • session[:key] = value doesn't work

    - by Bill Leeper
    I am trying to make use of session data in my application and for some reason I don't have something setup right. The code: session[:key] = some_value Generates the following error: The error occurred while evaluating nil.[] Other controllers don't have an issue with the session, so I am guessing I missed some basic configuration thing somewhere.

  • Rails layouts per action?

    - by mrbrdo
    I use a different layout for some actions (mostly for the new action in most of the controllers). I am wondering what the best way to specify the layout would be? (Consider like I am using 3 or more different layouts in the same controller) I don't like using render :layout = 'name' that much. I did like doing layout 'name', :only = [:new] but it turns out I can't use that to specify 2 different layouts (e.g. if I call layout 2 times in the same controller, with different layout names and different only options, the first one gets ignored - those actions don't display in the layout i specified). I'm using Rails 2.

  • validates_associated not honoring :if

    - by James Ferguson
    I'm totally blocked on this. See this pastie for sample code: http://pastie.org/990040 The first test will fail. The user model validates an associated address model, but is only supposed to do it if a flag is true. In practice it does it all the time. What is going on?

  • Conditional Branching Issues

    - by Zack
    Here is the code: def main_menu print_main_menu user_selected = gets.chomp if user_selected.downcase == "no" main_menu elsif user_selected == "1" || "2" || "3" || "4" || "5" || "6" || "7" user_selected = user_selected.to_i call_option(user_selected) else main_menu end end This code uses calls to allow a user to make a selection from a main menu. Depending on the input, be it a certain number, a certain word, or something else, the respective method is called (in the case of a valid input) or the main menu is printed again (in the case of an invalid input or "no"). My questions are twofold. 1) Is there an efficient way to get rid of the literal string error that appears as a result of this redundant or statement on the elsif line? (the code itself works fine, but this error appears and is frustrating). 2) When an alternate/unspecified input is made by the user, the else branch doesn't execute and main_method doesn't start over. I have no idea why this is happening. Is there something I'm missing here? Thanks

  • Selecting favourites from DB rails 3

    - by Richlewis
    I have a small app which has Users, Recipes, Ingredients and preparation models A user has many recipes, recipes belong to user and ingredients/preparation belongs to recipes. Now a user can view all recipes but I would like the option to add the particular recipe to a favourites list. Would I need to set a new DB to hold this and then link by associations or could I add a column to the recipe model called fav for example? Im looking for the best practice here or if someone has done this before and can offer any advice that would be appreciated

  • Multiple row insertion in a faster way

    - by Cyborgo
    Hi, I am using rails and I am trying to insert new rows into the table. The data comes from a text file and I created hash with one of the attribute as key. Then I find all the keys that are currently not in the table. Then I need to insert all of them into the table with all the attributes that I saved in hash. newvals.each{ |x| author = Author.create(:first => x, :second => hash[x][0], :third => hash[x][1]) author.save } This has lot of overhead as it makes an SQL update one at time. The newals array is usually quite big around the size of 20-30k. I know create can insert multiple objects at once, but I cant seem to figure out how. Is there any way to get this done. Thanks.

Anyone?

  • rails log rotation behaves weird (rails version 2.3.5)

    - by robodo
    I'm trying to setup log rotation in rails. I have put this in my environment/development.rb: config.logger = Logger.new("#{RAILS_ROOT}/log/#{ENV['RAILS_ENV']}.log", 1, 5*1048576) 2 files are created :-) but it looks like rails is writing to them randomly and at the same time as well. This creates messy log files :-( what am I missing?

  • Is it possible to have variable find conditions for both the key and value?

    - by DarrenD
    I'm trying to pass in both the field and the value in a find call: @employee = Employee.find(:all, :conditions => [ '? = ?', params[:key], params[:value].to_i) The output is SELECT * FROM `employees` WHERE ('is_manager' = 1) Which returns no results, however when I try this directly in mysqsl using the same call without the '' around is_manager, it works fine. How do I convert my params[:key] value to a symbol so that the resulting SQL call looks like: SELECT * FROM `employees` WHERE (is_manager = 1) Thanks, D

  • Rails 2.3.4 and jquery form plugin works on development, not in production?

    - by hemajang
    Hello, i'm trying to build a contact form in Rails 2.3.4. I'm using the jQuery Form plugin along with this (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) for validations. Everything works in my development environment (mac os x snow leopard), the loading gif appears and on my log the email gets sent and the "request completed" notice shows. But on my production machine the loading gif just keeps going and the form doesn't get sent. I've waited as long as I could, nothing. Here is my code: /public/javascripts/application.js // client-side validation and ajax submit contact form $('#contactForm').validate( { rules: { 'email[name]': { required: true }, 'email[address]': { required: true, email: true }, 'email[subject]': { required: true }, 'email[body]': { required: true } }, messages: { 'email[name]': "Please enter your name.", 'email[address]': "Please enter a valid email address.", 'email[subject]': "Please enter a subject.", 'email[body]': "Please enter a message." }, submitHandler: function(form) { $(form).ajaxSubmit({ dataType: 'script', beforeSend: function() { $(".loadMsg").show(); } }); return false; } }); I'm using the submitHandler to send the actual ajaxSubmit. I added the "dataType: "script" and the "beforeSubmit" for the loading graphic. def send_mail if request.post? respond_to do |wants| ContactMailer.deliver_contact_request(params[:email]) flash[:notice] = "Email was successfully sent." wants.js end end end Everything works fine on development, but not in production. What am I missing or did wrong?

  • has_many through and saving to join table

    - by Paul
    I have the following: class Invite < ActiveRecord::Base belongs_to :user has_many :invite_recipients has_many :recipients, :through => :invite_recipients end class InviteRecipient < ActiveRecord::Base belongs_to :invite belongs_to :user_comm validates_associated :user_comm, :invite validates_uniqueness_of :user_comm_id, :scope => :invite_id end class UserComm < ActiveRecord::Base end I'd like to create a method for Invite with invite_text and a list of UserComms as the variables and then have it create a new invite with the following validations: 1. All UserComms are unique 2. The invite isn't saved unless all the associated InviteRecipients are saved as well (in other words, the invite isn't valid unless all the created InviteRecipients are valid) I'm not familiar with how to create model functions. Moreover, when I try something like this: i = Invite.new(:invite_text => 'come join') ir1 = InviteRecipient.new(:invite => i, :user_comm => user_comm1) ir2 = InviteRecipient.new(:invite => i, :user_comm => user_comm2) i.invite_recipients = [uc1, uc2] i.save! I get: SystemStackError: stack level too deep

  • rails - REST or create another method

    - by user1304740
    Let's assume we have two models linked with a 1-to-many relationship (like clients and invoices - a client can have many invoices). In a view of a 'client' (let's say the 'show' view), there is a form to capture an 'invoice'. I found 2 approaches: This form should be handled by the 'invoice' controller (method create), having client_id passed as a parameter This form should be handled by a new method in 'client' controller, probably a PUT method defined in routes.rb. Is there a 'Rails way', or both of them are good? Is there a preffered way? Thanks!

  • How to override 'where' in rails 3

    - by Zakwan Alhajjar
    I have upgraded my application from rails 2.3.8 to 3.0.3 . But I'm facing a problem. I was using 'find' but the overriding doesn't work in rails 3: # override activerecord's find to allow us to find by name or id transparently def self.find(*args) if args.is_a?(Array) and args.first.is_a?(String) and (args.first.index(/[a-zA-Z\-_]+/) or args.first.to_i.eql?(0) ) find_by_login_slug(args) else super end end I'm wondering if there is a way to make this work in rails 3 or even by using where instead. thanks

Or I just have to convert the < and > by Javascript? Thank you :)

  • Rails: How to preload a message to user

    - by Michael
    I have a Rails based prelaunch site that has some rotating background images (which are important for selling the idea of the site) that are taking too long to load, such that the users are leaving the site before they load. The only thing they're seeing is the email submission box. What's a good way to show a message to the users that the site will take some time to load but then have that message disappear after a reasonable period of time. I'm guessing a jQuery fadeOut() with a timer, but I'm not sure how long to set the timer for, because I'm not sure at what time it would start counting. Any suggestions?
