  • 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.

  • Rapid Web Application Development ASP.net vs. Open Source Platforms

    - by Yaaqov
    Good morning - I'm an intermediate-level developer who wants to build on online data-driven app (CRUD with a few calculations and basic HTML form inputs, nothing fancy) that keeps track of user sessions, and looks "professional" (or at least not "homemade"). I'm looking to development something with the look-and-feel that users get from sites like: http://www.datamasher.org/ http://www.thisweknow.org/ (About page says it was made with Ruby on Rails, which I'm unfamiliar with) (stackoverflow.com) Any pointers on whether I should just go the Miscrosoft route, and develop in ASP.net with WebForms, or if there's a quick qay to do this kind of development (with a WYSIWYG environment) on an open-source platform? I'm willing to learn, if it's somethat I can use to quickly drag/drop, add code, and publish online. Templates would be a plus, too. I apologize is the question seems a bit vague.

  • What are the best practices for importing large datasets into MongoDB?

    - by snl
    We are just giving MongoDB a test run and have set up a Rails 3 app with Mongoid. What are the best practices for inserting large datasets into MongoDB? To flesh out a scenario: Say, I have a book model and want to import several million records from a CSV file. I suppose this needs to be done in the console, so this may possibly not be a Ruby-specific question. Edited to add: I assume it makes a huge difference whether the imported data includes associations or is supposed to go into one model only. Any comments on either scenario welcome.

  • How to program a Sort feature

    - by Brian Roisentul
    I'm working on Ruby on rails 2.3.4 and I'm trying to develop a Sort feature on my website's search page(its url is /anuncios/buscar). What I tried is to create a "map" on routes file: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' Then, I wrote this on the view: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance(@announcements) %> And finally, I created a method in the controller, as is specified on the routes' line: def search_filer_relevance raise params.inspect end First of all, as I'm sorting search results, I'd like to keep them in their public variable called @announcements. Please help me do this. An the other thing is that when I click the link I get an error due its trying to access the Show action instead of search_filter_relevance as specified in routes. Why is this happening?

  • Local variable not being passed to partial template by render?

    - by brad
    I don't seem to be able to pass a variable to my partial template in rails (2.3.5). My code is as follows; In the main view .html.erb file: <% f.fields_for :payments do |payment_form| %> <%= render 'payment', {:f => payment_form, :t => "test" } %> <% end %> and in the _payment.html.erb file: <%= t %> produces a wrong number of arguments (0 for 1) error. The payment_form object is being passed to the partial as f without any problems. I've tried a number of variations on the above syntax (e.g. :locals => {:f => payment_form, :t => "test" } without success. I presume I'm doing something pretty basic wrong but just can't see it.

  • how can I have a teammate restart heroku server from his machine

    - by josh
    I have a rails app up on heroku. Sometimes the server bombs out and I have to go to the console and execute heroku restart so that servers get restarted. This seems to fix the problem. However, I am not on my machine all the time. I would like to have a team member have this capability as well. For this to happen...what does he need to do? Does he need to first have access to the github repository so that he can push and pull code to the repository and then install heroku on his machine? Can this be done without git hub? can he just install heroku?

  • how to handle large dataset like sproutcore

    - by Nik
    Hello all, I really don't have any substantial code to show here, actually, that's kinda why I am writing: I looked at the SproutCore demo, especially the Collection demo, on http://demo.sproutcore.com/sample_controls/, and am amazed by its loading 200,000 records to the page so easily. I tried using Rails to provide 200,000 records and in a completely blank HTML page with <% @projects.each do |p| % <%= p.title % <% end % that freezes the browser for seconds on my m1530 laptop with 4gb ram and t7700 256gb ssd. Yet the sproutcore demo does not freeze and takes less than 3 seconds to load. What do you think the one technique they are using to enable this is? Thanks!

  • 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!

  • Store the day of the week and time

    - by bsiddiqui
    I have a two part question about storing day(s) of the week and time in a database. I'm using Rails 4.0, ruby 2.0.0, and postgres. I have certain events and those events have a schedule. For the event Skydiving for example, for example, I might have Tuesday and Wednesday and 3 pm. 1) Is there a way for me to store the the record for Tuesday and Wednesday in one row or do should I have two records? 2) What is the best way to store the day and time? Is there a way to store day of week and time (not datetime) or should these be separate columns? If they should be separate, how would you store day of week? I was thinking of storing them as integer values (0 for Sunday, 1 for Monday, etc) since that's how wday method for the Time class does it. Any suggestions would be super helpful. Thanks!

  • Heroku Postgres Error: PGError: ERROR: relation "organizations" does not exist (ActiveRecord::StatementInvalid)

    I'm having a problem deploying my Rails app to Heroku, where this error is thrown when trying to access the app: PGError: ERROR: relation "organizations" does not exist (ActiveRecord::StatementInvalid) SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull FROM pg_attribute a LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE a.attrelid = '"organizations"'::regclass AND a.attnum > 0 AND NOT a.attisdropped ORDER BY a.attnum Anybody have any ideas? This is a first for me, especially because I've been working with Heroku for a year on other apps, and haven't see anything like this. Of course, everything works on local SQLite. Thanks in advance for any help! --Mark

  • Can’t dup NilClass - how to trace to offender

    - by fullware
    This exception occurs often and intermittently when in development mode, and appears to get triggered by model associations. Does There are lots of references found by google but none seem to help to trace the problem to an offending class. Does anyone have any insight into how to trace the occurrence of this exception to it's cause? I've seen the posts on adding "unloadable" but I'm not sure I buy it--unless there's a way to trace it somehow to its cause. I'm not in favor of indiscriminately adding such things to every class in hopes the problem might go away. Rails 2.3.5.

  • Exporting ActiveRecord objects into POROs

    - by Lucas d. Prim
    Hello, I'm developing a "script generator" to automatize some processes at work. It has a Rails application running on a server that stores all data needed to make the script and generates the script itself at the end of the process. The problem I am having is how to export the data from the ActiveRecord format to Plain Old Ruby Objects (POROs) so I can deal with them in my script with no database support and a pure-ruby implementation. I tought about YAML, CSV or something like this to export the data but it would be a painful process to update these structures if the process changes. Is there a simpler way? Ty!

  • rake test and test_structure.sql

    - by korinthe
    First of all, I have to run "rake RAILS_ENV=test ..." to get the test suites to hit my test DB. Annoying but ok to live with. However when I do so, I get a long stream of errors like so: > rake RAILS_ENV=test -I test test:units psql:/path/to/project/db/test_structure.sql:33: ERROR: function "armor" already exists with same argument types [and many more] It looks like some DB definitions are getting unnecessarily reloaded. I can't find any mention of this on Google, so I was wondering whether others have seen this? I am using a PostgreSQL database with the following in my environment.rb: config.active_record.schema_format = :sql and using Rails 2.3.5 with rake 0.8.7.

  • Checking for duplicates with nested forms

    - by Cyrus
    I'm making a rails 3.2.9 app that allows users to create pages and they can embed youtube videos through a nested form. I'm trying to figure out how to make it so that I can prevent duplicate video records from being stored in my db. So I have a Video model that takes the youtube url and just parses out the video id and stores that instead of the full user submitted youtube url, which may have extraneous url query parameters. So here's the situation that I'm trying to figure out: There's page1 with video1 - url: 123 and video2 - url: abc Then another user creates page2 and submits video3 - url: def and video4 - url: 123 Currently each page has_many videos. But I think I should change it to a many-to-many relationship. But how would I make it so that the url submitted as video4 in the nested form points to video1? Also I how would I make a nested form that creates objects that are connected through a join table?

  • how can I add a new action to a controller?

    - by Angela
    I used the following in routes to add a new action to my Email controller: map.resources :emails, :member => { :newfwd => :put} The expected result was that newfwd_email_path(:id = 1) would generate the following urL: emails/1/newfwd It does. But I get an error, it treats '1' as an action and 'newfwd' as an id. I want '1' to be interpreted as the id for emails, upon which the newfwd action acts. I'm not sure what I'm doing wrong. (Note: I am using Rails 2.3.8)

    - by user179438
    Hi, I have a model I named User, and I want use two different Views to edit it: the usual edit view and another view I called edit_profile. I had no problem in creating routing, controller and views: I added edit_profile and update_profile views, and I added on routes.rb the line: map.resources :users ,:member => {:edit_profile => :get, :update_profile => :put} The problem is: when I submit the form in edit_profile and some error occur in some input fields, rails reload the edit_path page instead of edit_profile_path page ! This is the form on edit_profile.html.erb form_for(:user, @user, :url => {:action => :update_profile}, :html => { :method => :put} ) do |f| = f.text_field :description = f.text_area :description = f.error_message_on :description .... .... = f.submit 'Update profile' After clicking Update profile, if input errors occur I want to show edit_profile view instead of edit view Do You have some ideas ? many thanks

  • Ruby Hash.merge with specified keys only

    - by ba
    I'm pretty sure I saw on a Rails related site something along the lines of: def my_function(*opts) opts.require_keys(:first, :second, :third) end And if one of the keys in require_keys weren't specified, or if there were keys that weren't specified, an exception was raised. I've been looking through ActiveSupport and I guess I might be looking for something like the inverse of except. I like to try and use as much of the framework as possible compared to writing my own code, that's the reason I'm asking when I know how to make the same functionality on my own. :) At the moment I'm doing it through the normal merge routine and making sure that I have what I need with some IFs.

  • expiring image assets referenced from stylesheets

    - by crankharder
    So rails appends timestamps to CSS, JS and image files: image_tag 'foo.png' => <img src="foo.png?123123123123' /> # or somethin like that ...which is really useful for doing far-future expiration, etc. with Apache's help. But what about images referenced from stylesheets? They don't get an appended timestamp. So it seems to me that it's entirely possible to update one of those images, redeploy, and then not see the file change because the browser doesn't think it's been updated. Unless I'm missing something. If I'm not, is there a decent solution to this problem?

  • session variable not available in global before(:each, :type => :controller)

    Hi, I'm refactoring some specs, in controller specs I have a before(:each) which sets up things required in the session my before filter is... config.before(:each, :type => :controller) do ... session[:current_user] = @user session[:instance] = @instance ... end @user and @instance are also set in the before(:each) i've just hidden them for readability here I get the following error when running the controller tests undefined method `session' for nil:NilClass I would expect the global before callbacks to have the same things as the ones in the individual tests but I guess maybe they are loaded before the rails environment has been initialised? Thanks

  • is it possible to combine will_paginate with find_by_sql?

    In my rails application I want to use will_paginate plugin to paginate on my query. Is that possible? I tried doing something like this but it didn't work: @users = User.find_by_sql(" SELECT u.id, u.first_name, u.last_name, CASE WHEN r.user_accepted =1 AND (r.friend_accepted =0 || r.friend_accepted IS NULL) .........").paginate( :page => @page, :per_page => @per_page, :conditions => conditions_hash, :order => 'first_name ASC') If not, can you recommend a way around this or a way that might work as I don't want to write my own pagination.

  • Cannot call struct properties from HAML file

    I have the following code in my controller: @nav_items = ActiveSupport::OrderedHash.new @nav_items[:home] = Struct::NavItem.new("Home", nil, "/", "icon-home") @nav_items[:about] = Struct::NavItem.new("About", nil, "/about", "icon-heart") @nav_items[:contact] = Struct::NavItem.new("Contact", nil, "/contact", "icon-envelope") if (current_user != nil && current_user.admin?) @nav_items[:admin_divider] = Struct::NavItem.new(nil, "divider-vertical", nil, nil) @nav_items[:admin] = Struct::NavItem.new("Admin", nil, "/admin", "") end And the following in my view: - @nav_items.each do |nav_item| %li{ :class => nav_item[:class] } %a{ :href => nav_item[:link] }= nav_item[:text] And my struct definition: Struct.new("NavItem", :text, :class, :link, :icon_class) I'm relatively new to Ruby, Rails, and HAML, but in another project using ERB rendering, code like that worked fine. I've tried referencing properties by doing something like nav_item.link as well, but that still does not work. The error I get with my current code is: Symbol as array index By using code like nav_item.link: undefined method `link' for #< Array:0x126970ff0 As this is my first time using HAML, I'm not too sure what I'm doing wrong.
