  • Storing a variable into a database

    - by Alekx
    In an attempt to better learn Rails and I'm building a simple Blackjack game, but I'm running into a problem of storing the variable. I understand how to store user-genereated data into the db using form_for, but I'm struggling to create a random number and put it in the db. @hand = rand(9) + 2 I have "hand" as a field in my db, just curious how to store this random number. Any help anyone could provide to point me in the right direction would be very much appreciated. Thanks.

  • How can I return something early from a block?

    - by ryeguy
    If I wanted to do something like this: collection.each do |i| return nil if i == 3 ..many lines of code here.. end How would I get that effect? I know I could just wrap everything inside the block in a big if statement, but I'd like to avoid the nesting if possible.

  • sending specific data into a collection partial

    - by mikeglaz
    I have a User class with a has_many :messages and a Message class which belongs_to :user. In the Message controller's show action has the corresponding view: <% if @messages.any? %> <ol class="microposts"> <%= render partial: 'shared/message', collection: @messages %> </ol> <% end %> And the shared/_message.html.erb template looks like this: <li id="<%= message.id %>"> <span class="content"><%= message.body %></span> <% user_id = message.from %> <% user = User.find(user_id) %> From: <%= user.name %> </li> I feel like the following two lines should be done in the Messages controller from what I read in tutorials on Rails: <% user_id = message.from %> <% user = User.find(user_id) %> But how would I pass each message's corresponding from value (which stores user.id) into the partial? thanks, mike

  • Why is this line breaking Rails with Passenger on DreamHost?

    - by Frew
    Ok, so I have a Rails app set up on DreamHost and I had it working a while ago and now it's broken. I don't know a lot about deployment environments or anything like that so please forgive my ignorance. Anyway, it looks like the app is crashing at this line in config/environment.rb: require File.join(File.dirname(__FILE__), 'boot') config/boot.rb is pretty much normal, but I'll include it here anyway. # Don't change this file! # Configure your app in config/environment.rb and config/environments/*.rb RAILS_ROOT = "#{File.dirname(__FILE__)}/.." unless defined?(RAILS_ROOT) module Rails class << self def boot! unless booted? preinitialize pick_boot.run end end def booted? defined?

  • using helper methods in a view in rails 3

    - by Frida777
    Hello everyone, there is something that is disturbing me a bit about rails 3. i am trying to upgrade my application from rails 2 to rails 3. i followed all the steps necessary to do and things were working well for me till now except one thing: i have a helper method that is defined differently in different helpers, for example it is defined in the application_helper in one way and the same method defined in a different way in the homepage_helper, and defined differently in another helper, let's say video_helper, in addition to that, it is used in a shared view that is used throughout the application, now if i am in the homepage, i want this function to get called from the homepage_helper and if i am in the video page, the function must be called from the video_helper, based on the concept of convention in rails, this worked perfectly in rails 2 but in rails 3, the function is always called from the last helper, alphabetically ordered, that is in the example, video_helper. How can i fix this? Kindly advice. Appreciate all the help.

  • Devise role based routing

    - by teknull
    I have an app with multiple users. Each user as a theoretical role (user, client, etc). I've designed a view/controller for each user type. I want to be able to login each type of user do a different root url and lock them to it. Originally I was going to add a column to Users in Devise called role and so I can differentiate the users. The problem I'm having is how to say in routes.rb if current_user.role == "client" root :to = 'controller#index' Once they are logged in to the page I also want to keep them from being able to visit any of my other paths ie: domain.com/calls domain.com/units I've been looking into cancan to run alongside Devise but I'm not sure if this is the answer.

  • Fetch a Rails ActiveRecord 'datetime' attribute as a DateTime object.

    - by Tobias Cohen
    I have an attribute in one of my models that contains a Date/Time value, and is declared using t.datetime :ended_on in my migrations. When I fetch this value using myevent.ended_on, I get a Time object. The problem is that when I try to use this attribute as an axis in a Flotilla chart, it doesn't work properly because Flotilla only recognizes dates as Date or DateTime objects. I thought about writing a virtual attribute that will convert the existing Time value to a DateTime, but I'm wary of doing this, since I've heard that Time can't handle dates later than 2040, and I don't wish to risk creating a "2040 bug" to worry about later. Is there any way I can persuade ActiveRecord to return DateTime objects for this attribute instead of Time objects?

  • why is link generated in YUI javascript failing to render in rails?

    - by pmneve
    Using YAHOO.widget.treeview to generate a table with three levels of data: module, submodule, and detail. If there is an image associated with a detail row the javascript generates a link: "<td><a href=\"/screenshot/show/" + rowData.id + "\">Screenshot</a></td>" that is appended to the html for the row. The url is generated correctly and the link appears. When clicked nothing happens except the word 'Done' appears in the browser status bar. Am calling the very same url from another page that does not use javascript and the screenshot page appears as expected. Here is the controller. class ScreenshotController < ApplicationController def show if @detail.screen_path.length 1 @imagePath = "#{RAILS_ROOT}" + "/private/#{Company.find(@detail.company_id).subdir}/" + "#{Project.find(@detail.project_id).subdir}/screenshot/" + "#{@detail.screen_path}" send_file ( @imagePath, :type = 'image/jpeg', :disposition = 'inline') end end end A sample url: http://localhost:3004/screenshot/show/20854 This code from show.html.erb belonging to the detail model works: <%= link_to 'View', :controller = 'screenshot', :id = @detail.id, :action = 'show' % Any ideas???

  • javan-whenever not writing crontab with Capistrano deploy

    - by Gordon Isnor
    I’ve been trying to get whenever running on an ec2 instance that was created with ec2 on rails. When I deploy with Capistrano it indicates that the crontab was written, but when I log into the server and run crontab -l it does not seem to have been changed. If I go into the release folder and manually run whenever --write-crontab then run crontab -l - it gets updated properly. Any ideas what could be causing this? Capistrano is not indicating any errors so not sure how to debug, have tried a billion permutations and combinations and nothing changes.

  • How to add additional condition to the JOIN generated by include?

    - by KandadaBoggu
    I want to add additional criteria to the LEFT OUTER JOIN generated by the :include option in ActiveRecord finder. class Post has_many :comments end class Comment belongs_to :post has_many :comment_votes end class CommentVote belongs_to :comment end Now lets say I want to find last 10 posts with their associated comments and the up comment votes. Post.find.all(:limit => 10, :order => "created_at DESC", :include => [{:comments => :comment_votes]) I cant add the condition to check for up votes as it will ignore the posts without the up votes. So the condition has to go the ON clause of the JOIN generated for the comment_votes. I am wishing for a syntax such as: Post.find.all(:limit => 10, :order => "created_at DESC", :include => [{:comments => [:comment_votes, :on => "comment_votes.vote > 0"]) Have you faced such problems before? Did you managed to solve the problem using the current finder? I hope to hear some interesting ideas from the community. PS: I can write a join SQL to get the expected result and stitch the results together. I want to make sure there is no other alternative before going down that path.

  • Error when rendering a partial (RoR) passing the form as a local variable

    - by Dmitriy Likhten
    In my main template I have the following: <%= render :partial => "delivery_date", :collection => @brand.delivery_dates, :locals => {:form => f} %> However when the partial tries to use the form local variable, I get this error Showing app/views/brands/_delivery_date.html.erb where line #2 raised: wrong number of arguments (0 for 1) Extracted source (around line #2): 1: <%= delivery_date.id %> 2: <%= form.text_field :name %> 3: <% new_or_existing = delivery_date.new_record? ? 'new' : 'existing' %> 4: <% prefix = "brand[#{new_or_existing}_delivery_date_attributes][]" %> 5: <% fields_for prefix, delivery_date do |dd_f| %> Does anyone understand what this error means? Actually I want to do <% form.fields_for delivery_date do |dd_f| %> but that fails as well.

  • Rendering partial for table row with form_tag is getting crazy!

    - by xopht
    I have 23(column)x6(row) table and change the row with link_to_remote function. each tr tag has its own id attribute. change link call change action and change action changes the row using render function wit partial. _change.html.erb <td id="row_1">1</td> . . omitted . . <td id="row_23">23</td> link_to_remote function <%= link_to_remote 'Change', :update => 'row_1', :url => change_path %> change action def change logger.debug render :partial => 'change' end If I coded like above, everything work okay. This means all changed-columns are in one row. But, if I wrap partial code with *form_for* function like below... <% form_for 'change' do %> <td id="row_1">1</td> . . omitted . . <td id="row_23">23</td> <% end %> Then, one column located in one row and that column is the first column. I've looked up the log file, but it was normal html tags. What's wrong?

  • Heroku only initializes some of my models.

    - by JayX
    So I ran heroku db:push And it returned Sending schema Schema: 100% |==========================================| Time: 00:00:08 Sending indexes schema_migrat: 100% |==========================================| Time: 00:00:00 projects: 100% |==========================================| Time: 00:00:00 tasks: 100% |==========================================| Time: 00:00:00 users: 100% |==========================================| Time: 00:00:00 Sending data 8 tables, 70,551 records groups: 100% |==========================================| Time: 00:00:00 schema_migrat: 100% |==========================================| Time: 00:00:00 projects: 100% |==========================================| Time: 00:00:00 tasks: 100% |==========================================| Time: 00:00:02 authenticatio: 100% |==========================================| Time: 00:00:00 articles: 100% |==========================================| Time: 00:08:27 users: 100% |==========================================| Time: 00:00:00 topics: 100% |==========================================| Time: 00:01:22 Resetting sequences And when I went to heroku console This worked >> Task => Task(id: integer, topic: string, content: string, This worked >> User => User(id: integer, name: string, email: string, But the rest only returned something like >> Project NameError: uninitialized constant Project /home/heroku_rack/lib/console.rb:150 /home/heroku_rack/lib/console.rb:150:in `call' /home/heroku_rack/lib/console.rb:28:in `call' >> Authentication NameError: uninitialized constant Authentication /home/heroku_rack/lib/console.rb:150 /home/heroku_rack/lib/console.rb:150:in `call' update 1: And when I typed >> ActiveRecord::Base.connection.tables it returned => ["projects", "groups", "tasks", "topics", "articles", "schema_migrations", "authentications", "users"] Using heroku's SQL console plugin I got SQL> show tables +-------------------+ | table_name | +-------------------+ | authentications | | topics | | groups | | projects | | schema_migrations | | tasks | | articles | | users | +-------------------+ So I think they are existing in heroku's database already. There is probably something wrong with rack db:migrate update 2: I ran rack db:migrate locally in both production and development modes and nothing wrong happened. But when I ran it on heroku it only returned: $ heroku rake db:migrate (in /disk1/home/slugs/389817_1c16250_4bf2-f9c9517b-bdbd-49d9-8e5a-a87111d3558e/mnt) $ Also, I am using sqlite3 update 3: so I opened up heroku console and typed in the following command class Authentication < ActiveRecord::Base;end Amazingly I was able to call Authentication class, but once I exited, nothing was changed.

  • Rails 3 HABTM Strange Association: Project and Employee in a tree.

    - by Mauricio
    Hi guys I have to adapt an existing model to a new relation. I have this: A Project has many Employees. the Employees of a Project are organized in some kind of hierarchy (nothing fancy, I resolved this adding a parent_id for each employee to build the 'tree') class Employee < AR:Base belongs_to :project belongs_to :parent, :class_name => 'Employee' has_many :childs, :class_name => 'Employee', :foreign_column => 'parent_id' end class Project < AR:Base has_many :employees, end That worked like a charm, now the new requirement is: The Employees can belong to many Projects at the same time, and the hierarchy will be different according to the project. So I though I will need a new table to build the HABTM, and a new class to access the parent_id to build the tree. Something like class ProjectEmployee < AR:Base belongs_to :project belongs_to :employee belongs_to :parent, :class_name => 'Employee' # <--- ?????? end class Project < AR:Base has_many :project_employee has_many :employees, :through => :project_employee end class Employee < AR:Base has_many :project_employee has_many :projects, :through => :project_employee end How can I access the parent and the childs of an employee for a given project? I need to add and remove childs as wish from the employees of a project. Thank you!

  • How do I create another controller action to create an object in rails?

    - by Angela
    I have a model called Contact_Email. When an Email template is sent through ActionMailer to a specific Contact, as part of the Create action it sends it through upon .save. However, I want to create a "skip" action which also creates a Contact_Email, but does NOT send an ActionMailer and allows me to set the status differently. I want to create a separate action because I want to make this respond to a remote_for_tag so that I can just have an ajax button indicate it has been "skipped": Here's what I tried, but while it creates a Contact_Email, I end up getting an error when I want to go back and view all the Contacts again. def skip @contact_email = ContactEmail.new @contact_email.contact_id = params[:contact_id] @contact_email.email_id = params[:email_id] @contact_email.status = "skipped" if @contact_email.save flash[:notice] = "skipped email" redirect_to contact_emails_url end end

  • Using an observer within an Engine

    - by Tim
    I've created an Engine which is basically used for all of our projects. Now what I want to do is add a before_create callback to all of the models in this Engine. After some searching I found out that an observer is the way to go. So, I've created this observer: class AuthObserver < ActiveRecord::Observer def before_create( record ) p record end end And now I need to add it to the application, but of course in my Engine there is no such file as application.rb. What I tried is adding it to an initializer located in /config/initializers/observers.rb Like so: Rails.application.config.active_record.observers = :auth_observer But this doesn't work, and it throws no errors. Anybody out here has experience using an observer inside an engine? Thanks a lot!

  • How to replace href using javascript regex in Firefox?

    - by Andrei
    I try to change some links on a webpage using the following code for jQuery on Rails $(function () { $('#lesson a').live('click', function () { $.getScript(this.href.replace(/^(http...[^\/]+)?\/+(.*)$/,'/ajax/\\$2')); return false; }); }) This trick works for Chrome and Safari, but fails (nothing happens on click) for Firefox and Opera. What can be wrong with the code? EDIT1: The webpage contains: <div id="lesson"> <a href="/subj1">Subject 1</a> ... </div> On click, a browser (i.e. Firefox and Opera) should make an ajax-request of /ajax/subj1.
