  • Can't figure out how to use db:seed for rails in netbeans

    - by user317766
    can't seem to get my seeds.rb file to run through the command "rake db:seed". I'm using netbeans and I'm a beginner to rails, so I could be doing something really simple and stupid =/. I know you're meant to put your seeds.rb file in the db directory but netbeans doesn't seem to have one or might have renamed it... any help out there? Thanks in advance!

  • How do I use accepts_nested_attributes_for? I cannot use the .build method (!)

    - by Angela
    Editing my question for conciseness and to update what I've done: How do I model having multiple Addresses for a Company and assign a single Address to a Contact, and be able to assign them when creating or editing a Contact? Here is my model for Contacts: class Contact < ActiveRecord::Base attr_accessible :first_name, :last_name, :title, :phone, :fax, :email, :company, :date_entered, :campaign_id, :company_name, :address_id, :address_attributes belongs_to :company belongs_to :address accepts_nested_attributes_for :address end Here is my model for Address: class Address < ActiveRecord::Base attr_accessible :street1, :street2, :city, :state, :zip has_many :contacts end I would like, when creating an new contact, access all the Addresses that belong to the other Contacts that belong to the Company. So here is how I represent Company: class Company < ActiveRecord::Base attr_accessible :name, :phone, :addresses has_many :contacts has_many :addresses, :through => :contacts end Here is how I am trying to create a field in the View for _form for Contact so that, when someone creates a new Contact, they pass the address to the Address model and associate that address to the Contact: <% f.fields_for :address, @contact.address do |builder| %> <p> <%= builder.label :street1, "Street 1" %> </br> <%= builder.text_field :street1 %> <p> <% end %> When I try to Edit, the field for Street 1 is blank. And I don't know how to display the value from show.html.erb. At the bottom is my error console -- can't seem to create values in the address table: My Contacts controller is as follows: def new @contact = Contact.new @contact.address.build # I GET AN ERROR HERE: says NIL CLASS @contact.date_entered = Date.today @campaigns = Campaign.find(:all, :order => "name") if params[:campaign_id].blank? else @campaign = Campaign.find(params[:campaign_id]) @contact.campaign_id = @campaign.id end if params[:company_id].blank? else @company = Company.find(params[:company_id]) @contact.company_name = @company.name end end def create @contact = Contact.new(params[:contact]) if @contact.save flash[:notice] = "Successfully created contact." redirect_to @contact else render :action => 'new' end end def edit @contact = Contact.find(params[:id]) @campaigns = Campaign.find(:all, :order => "name") end Here is a snippet of my error console: I am POSTING the attribute, but it is not CREATING in the Address table....

  • Rails: vendor/gems or vendor/plugins?

    - by TheDeeno
    I'm attempting to track my dependencies with git-submodules in my rails app. So far I've added submodules for things like, haml, shoulda, authlogic, etc to 'vendor/plugins'. I've seen indications that I should be using 'vendor/gems' instead though. Question, which directory is the appropriate place to put dependencies being tracked as submodules? Is the choice arbitrary? Thanks

  • IRB and large variables?

    - by tesmar
    How can I print a large variable nicely in an irb prompt? I have a variable that contains many variables which are long and the printout becomes a mess to wade through. What if I just want the variable names without their values? Or, can I print each one on a separate line, tabbed-in depending on depth?

  • Ajax, Multiple Attachments and Paperclip question.

    - by dustmoo
    Alright everyone this is a bit of a complicated setup so if I need to clarify the question just let me know. I have a model: class IconSet < ActiveRecord::Base has_many :icon_graphics end This Model has many icongraphics: class IconGraphic < ActiveRecord::Base belongs_to :icon_set has_attached_file :icon has_attached_file :flagged end As you can see, IconGraphic has two attached files, basically two different versions of the icon that I want to load. Now, this setup is working okay if I edit the icongraphic's individually, however, for ease of use, I have all the icon graphics editable under the IconSet. When you edit the icon set the form loads a partial for the icongraphics: <% form_for @icon_set, :html => {:class => 'nice', :multipart => true} do |f| %> <fieldset> <%= f.error_messages %> <p> <%= f.label :name %> <%= f.text_field :name, :class => "text_input" %> </p> <!-- Loaded Partial for icongraphics --> <div id="icon_graphics"> <%= render :partial => 'icon_graphic', :collection => @icon_set.icon_graphics %> </div> <div class="add_link"> <%= link_to_function "Add an Icon" do |page| page.insert_html :bottom, :icon_graphics, :partial => 'icon_graphic', :object => IconGraphic.new end %> </div> <p><%= f.submit "Submit" %></p> </fieldset> <% end %> This is based largely off of Ryan's Complex Forms Railscast. The partial loads the file_field forms: <div class="icon_graphic"> <% fields_for "icon_set[icon_graphic_attributes][]", icon_graphic do |icon_form|-%> <%- if icon_graphic.new_record? -%> <strong>Upload Icon: </strong><%= icon_form.file_field :icon, :index => nil %><br/> <strong>Upload Flagged Icon: </strong><%= icon_form.file_field :flagged, :index => nil %> <%= link_to_function image_tag('remove_16.png'), "this.up('.icon_graphic').remove()"%><br/> <% else -%> <%= image_tag icon_graphic.icon.url %><br/> <strong>Replace <%= icon_graphic.icon_file_name %>: </strong><%= icon_form.file_field :icon, :index => nil %><br /> <% if icon_graphic.flagged_file_name.blank? -%> <strong>Upload Flagged Icon: </strong><%= icon_form.file_field :flagged, :index => nil %> <% else -%> <strong>Replace <%= icon_graphic.flagged_file_name %>: </strong><%= icon_form.file_field :flagged, :index => nil %> <%= icon_form.hidden_field :flagged, :index => nil %> <% end -%> <%= link_to_function image_tag('remove_16.png'), "mark_for_destroy(this, '.icon_graphic')"%><br/> <%= icon_form.hidden_field :id, :index => nil %> <%= icon_form.hidden_field :icon, :index => nil %> <%= icon_form.hidden_field :should_destroy, :index => nil, :class => 'should_destroy' %> <br/><br/> <%- end -%> <% end -%> </div> Now, this is looking fine when I add new icons, and fill both fields. However, if I edit the IconSet after the fact, and perhaps try to replace the icon with a new one, or if I uploaded only one of the set and try to add the second attachment, paperclip doesn't put the attachments with the right IconGraphic Model. It seems that even though I have the IconGraphic ID in each partial, <%= icon_form.hidden_field :id, :index => nil %> it seems that paperclip either creates a new IconGraphic or attaches it to the wrong one. This all happens when you save the IconSet, which is setup to save the IconGraphic attributes. I know this is complicated.. I may just have to go to editing each icon individually, but if anyone can help, I would appreciate it.

  • Rails new vs create

    - by Senthil
    Why is there a need to define a new method in RESTful controller, follow it up with a create method? Google search didn't provide me the answer I was looking for. I understand the different, but need to know why they are used the way they are.

  • ActiveRecord Logic Challenge - Smart Ways to Use AR Timestamp

    - by keruilin
    My question is somewhat specific to my app's issue, but the answer should be instructive in terms of use cases for association logic and the record timestamp. I have an NBA pick 'em game where I want to award badges for picking x number of games in a row correctly -- 10, 20, 30. Here are the models, attributes, and associations in-play: User id Pick id result # (values can be 'W', 'L', 'T', or nil. nil means hasn't resolved yet.) resolved # (values can be true, false, or nil.) game_time created_at *Note: There are cases where a pick's result field and resolved field will always be nil. Perhaps the game was cancelled. Badge id Award id user_id badge_id created_at User has many awards. User has many picks. Pick belongs to user. Badge has many awards. Award belongs to user. Award belongs to badge. One of the important rules here to capture in the code is that while a user can be awarded multiple streak badges (e.g., a user can win multiple 10-streak badges), the user CAN'T be awarded another badge for consecutive winning picks that were previously granted an award badge. One way to think of this is that all the dates of the winning picks must come after the date that the streak badge was awarded. For example, let's pretend that a user made 13 winning picks from May 5 to May 8, with the 10th winning pick occurring on May 7, and the last 3 on May 8. The user would be awarded a 10-streak badge on May 7. Now if the user makes another winning pick on May 9, the code must recognize that the user only has a streak of 4 winning picks, not 14, because the user already received an award for the first 10. Now let's assume that the user makes 6 more winning picks. In this case, the code must recognize that all winning picks since May 5 are eligible for a 20-streak badge award, and make the award. Another important rule is that when looking at a winning streak, we don't care about the game time, but rather when the pick was made (created_at). For example, let's say that Team A plays Team B on Sat. And Team C plays Team D on Sun. If the user picks Team C to beat Team D on Thurs, and Team A to beat Team C on Fri, and Team A wins on Sat, but Team C loses on Sun, then the user has a losing streak of 1. So when must the streak-check kick-in? As soon as a pick is a win. If it's a loss or tie, no point in checking. One more note: if the pick is not resolved (false) and the result is nil, that means the game was postponed and must be factored out. With all that said, what is the most efficient, effective and lean way to determine whether a user has a 10-, 20- or 30-win streak?

  • PDF to PNG Processor - Paperclip

    - by Josh Crowder
    I am trying to develop a system in which a user can upload a slideshow (pdf) and it'll export each slide as a png. After some digging around I came across a post on here that suggested using a processor. I've had a go, but I cant get the command to run, if it is running then I don't know what is happening because no errors are being shown. Any help would be appreciated! module Paperclip class Slides < Processor def initialize(file, options = {}, attachment = nill) super @file = file @instance = options[:instance] @current_format = File.extname(@file.path) @basename = File.basename(@file.path, @current_format) end def make dst = Tempfile.new( [ @basename, @format].compact.join(".")) dst.binmode command = <<-end_command -size 640x300 #{ File.expand_path(dst.path) } tester.png end_command begin success = Paperclip.run("convert", command.gsub(/\s+/, " "))) rescue PaperclipCommandLineError raise PaperclipError, "There was an error processing the thumbnail for #{@basename}" end end end end I think my problem is with the convert command... When I run that command by hand, it works but it doesn't give the details of each slide it just executes it. What I need to happen is once its made all the slides, pass back the data to a new model... or I know where all the slides are, but once I get to that point I'm not sure what todo.

  • Solution for social network + marketplace with multiple sellers?

    - by user261231
    I want to build a social network, with some of the users being able to put up some stuff up for sale. So basically, a social network + multiple sellers e-commerce. What is the best technology solution for that? I was thinking of going Rails route, using CommunityEngine and ActiveMerchant. Another option is going PHP and using something like X-Cart, which already has multiple sellers interface. Any recommendations? Thanks!

  • Rails routing problem

    - by Steve
    I am new to Rails routing and I currently have a problem and hope someone can explain it to me. I am using Rails 2.3.5 Firstly, let me describe my working-fine code: I have a text example, which has a controller (cars_controller) with an update action (along with some other actions). The update action needs the :id parameter. The edit.html.erb has a form: <% form_for :car, :url = {:controller = 'cars', :action = 'update' } % ... # rest of the form content. In the configuration/routes.rb, I have a self-defined routing rule for update: map.connect 'car/update/:id', :controller = 'cars', :action = 'update' This works fine. Secondly, I change the code. All I change is the self-defined routing rule to map.connect 'car/:action/:id, :controller = 'cars' To me, this rule covers the self-written routing rule. Of course, this rule is also used by other actions such as edit. But the edit.html.erb doesn't work. It complains that update action misses the :id parameter. I have to change the form_for helper to: <% form_for :car, :url = {:controller = 'cars', :action = 'update', :id = @car }% ... # @car is the instance passed to edit view. I know that if missing the :id parameter, update action will complain. What I don't understand is why my first code works (with my self-defined routing rule) but my second code fails. It seems to me that I didn't provide :id parameter in my self-defined routing rule. Anyone has an idea?

  • Google Maps integration with JSON - CircularReferenceError

    - by JZ
    I'm working on Rails 3.0.0.beta2, following Advanced Rails Recipes "Recipe #32, Mark locations on a Google Map" and I hit a road block. The following code is returning a "ActiveSupport::JSON::Encoding::CircularReferenceError" "object references itself" at line 3. This code represents the /layouts/maps.html.erb file <% if @maps -%> <script type="text/javascript"> var maps = <%= @maps.to_json %>; </script> <% end -%> This is my first attempt at rendering JSON, and I don't know how to debug this problem. Do you have experience with this? What could cause this problem? Thank you in advance!

  • Securely persist session between https://secure.yourname.com and http://www.yourname.com on rails ap

    - by Matt
    My rails site posts to a secure host (e.g. 'https://secure.yourname.com') when the user logs into the site. Session data is stored in the database, with the cookie containing only the session ID. The problem is that when the user returns to a non-https page, such as the home page (e.g. 'http://www.yourname.com') the user appears to have logged out. I believe the reason for this is that a separate cookie is stored for each host (www vs. secure). Is this correct? What is the best secure way to persist the session between both the http and https sections of the site? Does anyone know of any plugins that address this problem? The site runs on Heroku.

  • Is it Me or Are Rails and Django Difficult to Install on Windows?

    - by Mackristo
    I tried getting these frameworks working on Windows Vista for a couple of days but to no avail. Every single time I thought I had them working I would get some random error involving the PostgreSQL or MySQL setup, or the paths were screwed up or some other command line error "not recognized as an internal or external command" (or something). Someone told me that these frameworks are a lot easier to get running on Ubuntu but I really don't want to make that switch as everything I have is on Windows. Are these common problems when trying to get running on Windows? I think I'll just stick with C# and .NET as everything seems to work pretty nicely together with none of this "install-twenty-different-components" stuff and see if they work together. Is Instant Django advisable to use?

  • Rails, How can I combine multiple model attributes to create a unique permalink using permalink_fu?

    - by Ranknoodle
    Can Permalink_fu combine 2 or more model attributes to create a unique permalink? Let's say I have a Business Model, this model contains :name, :address, :phone, :city, :state, :country etc. attributes. Right now I have permalink set up in this model only for :name has_permalink :name So I would get "/biz/name". However I would like to combine the Business name, city, and a incremental number if there are more than 1 location in the city for that business. For example I would like to use: "/biz/joes-coffee-shack-chicago" for the permalink or if a multple location business "/biz/starbucks-chicago-92" Is this possible with the current permalink_fu plugin or some fork of permalink_fu? Or will this require some modification to the permalink_fu plugin?

  • Are these settings correct for sending mail through Rails/Gmail?

    - by aressidi
    Hi there, I spend a good deal of time building an email system for my Rails app that uses Gmail to send bulk mail to a list of opt-in users. I realize a shortcomming of using Google Apps for my mail, namely a rate limit on the number of emails it will send out (i believe 500). Anyway, I have reached out to my users to see how many have received the email, and a lot of them have not, though some have. The list I tried sending to was about 540 users, so I would have expected more "yes, got it," then "nope, still waiting" responses. I have two questions: Do these settings look correct for outgoing bulk mailing through Gmail? Again, using google apps to manage my domain and i know some people (including myself) have received the mailer. This is in a mail.rb initializer in my app. ActionMailer::Base.delivery_method = :sendmail ActionMailer::Base.smtp_settings = { :address => "smtp.gmail.com", :port => 25, :domain => "mydomain.com", :authentication => :login, :user_name => "[email protected]", :password => "mypass" } Is there any way I can test if the mail was delivered, or at least attempted to be delivered? I can't tell where in the list the mailer stops mailing! The way I generate the list is through a query which then passes the user info to a mailer worker which sends the emails out via Starling/Workling. Any advice here would be useful. Happy to post code, but want to make sure the method I'm using is sound. Thanks for the help!

  • Rails accepts_nested_attributes_for callbacks

    - by Rabbott
    I have two models Ticket and TicketComment, the TicketComment is a child of Ticket. ticket.rb class Ticket < ActiveRecord::Base has_many :ticket_comments, :dependent => :destroy, :order => 'created_at DESC' # allow the ticket comments to be created from within a ticket form accepts_nested_attributes_for :ticket_comments, :reject_if => proc { |attributes| attributes['comment'].blank? } end ticket_comment.rb class TicketComment < ActiveRecord::Base belongs_to :ticket validates_presence_of :comment end What I want to do is mimic the functionality in Trac, where if a user makes a change to the ticket, and/or adds a comment, an email is sent to the people assigned to the ticket. I want to use an after_update or after_save callback, so that I know the information was all saved before I send out emails. How can I detect changes to the model (ticket.changes) as well as whether a new comment was created or not (ticket.comments) and send this update (x changes to y, user added comment 'text') in ONE email in a callback method?

  • Has any one used client_side_validations gem with Chosen.js dropdown?

    - by Abid
    I am using chosen.js (http://harvesthq.github.com/chosen/). I was wondering if anyone has been able to use chosen select boxes and client_side_validations together. The issue is that when we use chosen it hides the original select element and renders its own dropdown instead, and when we focus out the validation isn't called and also when the validation message is shown it is shown with the original select element so positioning of the error isnt also correct. What could be a good way to handle this, My be we can change some code inside ActionView::Base.field_error_proc which currently looks something like ActionView::Base.field_error_proc = Proc.new do |html_tag, instance| unless html_tag =~ /^<label/ %{<div class="field_with_errors">#{html_tag}<label for="#{instance.send(:tag_id)}" class="message">#{instance.error_message.first}</label></div>}.html_safe else %{<div class="field_with_errors">#{html_tag}</div>}.html_safe end end Any ideas ? Edit 1: I have the following solution that is working for me now. applied a class "chzn-dropdown" to all my selects that were being displayed by chosen used the following callback provided by client_side_validations Gem clientSideValidations.callbacks.element.fail = function(element, message, callback) { if (element.data('valid') !== false) { if(element.hasClass('dropdown')){ chzn_element = $('#'+element.attr('id')+'_chzn'); console.log(chzn_element); chzn_element.append(""+message+""); } else{ callback(); } } } Thanks

  • adding visual effects to RJS before action rendered

    - by Sam
    I just started using RJS which is awesome however I am used to putting visual effects in the link_to_remote and such and I'm not sure how to trigger actions before and after remotes are triggered. Take this link for example: HTML <span id="<%= "edit_comment_link_#{comment.id.to_s}"%>" style="float:left;"> <%= link_to_remote "edit", {:update => "comment_#{comment.id.to_s}", :url => edit_post_comment_path(comment.post, comment), :method => :get}%> | </span> Controller: def edit @comment = Comment.find(params[:id]) respond_to do |format| #format.html render edit_comment_path(@comment) format.js end end RJS: page.replace_html "edit_comment_link_#{@comment.id.to_s}", "currently editing | " So is RJS mainly for after actions are rendered visual effects such as a spinner should be put into the link_to_remote with call_backs? Is this a good way of doing things?
