• Rails + facebox + authlogic - how?

  - by Vitaly

  Hello, on my web site I want to have login/registration form in modal window done using facebox (jQuery plugin). What is better: Create view with one method and template that has form and refer facebox to this view. Create static HTML file in public directory and refer facebox to this static page. What I want to achieve is: Easy verification (like "user name already taken", "password confirmation doesn't match password" and stuff like that). Easy submit and redirect I'm new to Rails, I just know about forms verification in Django, so for Django I would probably choose option 1, but it might be another thing in Ruby.

• Link redirects to "show" action instead of the indicated in routes.rb

  - by Brian Roisentul

  I'm working with Ruby on rails 2.3.4 and I'd like to have a link that executes an action when clicked. The relevant part of the routes.rb file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' My view(it's the model's index page) looks like this: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> And my controller looks like this: def search_filter_relevance raise params.inspect unless params[:announcements].nil? or params[:announcements].empty? @announcements = params[:announcements].order_by_featured end end The problem is that when I click the link I get an error due to some null value in the Show action! I'm not accessing that action at all...why is executing it?

• Make Sphinx quiet (non-verbose)

  - by J. Pablo Fernández

  I'm using Sphinx through Thinking Sphinx in a Ruby on Rails project. When I create seed data and all the time, it's quite verbose, printing this: using config file '/Users/pupeno/projectx/config/development.sphinx.conf'... indexing index 'user_delta'... collected 7 docs, 0.0 MB collected 0 attr values sorted 0.0 Mvalues, 100.0% done sorted 0.0 Mhits, 99.6% done total 7 docs, 159 bytes total 0.042 sec, 3749.29 bytes/sec, 165.06 docs/sec Sphinx 0.9.8.1-release (r1533) Copyright (c) 2001-2008, Andrew Aksyonoff for every record that is created or so. Is there a way to suppress that output?

• GEM Version Requirements Depreciated

  - by Kevin Sylvestre

  When creating a new Rails project using: rails sample Then creating a model using: script/generate model person first_name:string last_name:string Everything is fine. However, if I add any gems to my environment.rb: config.gem "authlogic" And run the same generator, I get the following: /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. The warning just recently appeared (I think), but I would like to fix it if possible. Any hints or similar experiences? Thanks.

• How can I embed the result of a rails view in another website?

  - by NotDan

  I would like to allow users to call my ruby on rails app as a service which returns a 'div' with html content in it, and embed that div into their app (which will not be a rails application). For example, assume someone has their own php website that has a header/footer template that gets rendered, and a content area of the page that they need to fill based on some html I generate in my rails app. I would like to allow them, from php, to call to my website, get the 'div' I generate, and embed that as html in their php page. What I'm trying to do is host a service on my site that returns some html content, but actually show that content as part of another site, so that the end user only sees the other site and never really knows about mine. Is this possible?

• Learning rails and AJAX. How do I load a div via ajax and then toggle hiding/showing it?

  - by Kevin L.

  I'm doing my first Ruby on Rails project. I am working on a project where the user can add a new message. Then they can add updates to this message like a thread. I've got it all written and now I'm going back and applying some AJAX. I want to show just the main message when the page first loads. Then when I click a link I want an AJAX event to fire that populates a div with all the updates to the message. Then I want this same link to toggle hiding and showing the div. I've made a submit button to fire the ajax and get back the updates using form_remote_tag. I've also created a separate link to toggle the hiding using $(div_id).toggle();. But now I'm stuck on how to combine these two things into one all purpose link. Thanks.

• Unrecognized authentication type when doing an Auth to Exchange from Rails

  - by blakeage

  I'm getting this error when trying to authenticate with Exchange Server from Ruby on Rails: 504 5.7.4 Unrecognized authentication type config.action_mailer.raise_delivery_errors = true config.action_mailer.perform_deliveries = true config.action_mailer.delivery_method = :smtp config.action_mailer.smtp_settings = { :address => "x.x.x.x", :port => 25, :user_name => "xxdomain\xxuser", :password => "xxxxxx", :authentication => :login, :enable_starttls_auto => true } I've tried all sorts of combinations of configuration settings, including changing the settings to use "plain" authentication, adding the domain, setting enable_starttls_auto to true, false, and removing it entirely, removing the port. Nothing has worked. Any ideas?

• How to not encapsulate Coffeescript

  - by JellicleCat

  I don't know whether all coffeescript compilers wrap their scripts in anonymous functions, but that's what I see Rails doing. How can I disable this encapsulation? I want to put several initializing functions in a single coffeescript file, then call one of them from an on-page <script> tag (so that each page calls a different initializer). This can't be if the initializing functions are encapsulated. Coffeescript initializer functions: initializerA = -> console.log 'foo' initializerB = -> console.log 'bar' On-page code: <script>$(document).ready(initializerA)</script> Sys: coffee-rails 3.2.1, Rails 3.2.3, Ruby 1.9.3

• I get "stack level too deep" error when using a named scope

  - by Brian Roisentul

  I'm using ruby on rails 2.3.8 and when I write the syntax shown below I get the "stack level too deep" error message. The model is called Announcement and the line of the error looks like this: Tag.find(category_id).announcements.published Where published is named_scope :published, :conditions => "announcements.state = 'published'" I use this named scope in many other places and it works fine. What am I doing wrong? (the relationship between Tag and Announcement model is ok because if I remove the ".published" method from that line it works just fine).

• How do you share pre-calculated data between calls to a Rails web service?

  - by Nigel Thorne

  I have a Rails app that allows users to build up a network structure and then ask questions about how to navigate around it. When adding nodes and connections these are just saved to the database. At the point you make a query of the network I calculate the shortest path from any node to any other node. Constructing this in memory takes a while (something I need to fix), but once it is there, you can instantly get the answer to any of these path questions. The question is... How do I share this network between calls to the website, so each request doesn't regenerate the paths network each time? Note: I am hosting this on apache server using passenger (mod ruby) Thoughts?

• Dynamic path in new.AjaxRequest with Rails

  - by Robbie

  Hello, I was wondering if there's anyway to get a 'dynamic path' into a .js file through Ruby on Rails. For example, I have the following: new Ajax.Request('/tokens/destroy/' + GRID_ID, {asynchronous:true, evalScripts:true, onComplete:function(request){load('26', 'table1', request.responseText)}, parameters:'token=' + dsrc.id + '&authenticity_token=' + encodeURIComponent(AUTH_TOKEN)}) The main URL is '/tokens/destroy/:id', however on my production server this app runs as a sub folder. So the URL for this ajax call needs to be '/qrpsdrail/tokens/destroy/:id' The URL this is being called from would be /grids/1 or /qrpsdrail/grids/1 I could, of course, do ../../path -- but that seems a bit hackish. It is also dependent on the routing never changing, which at this stage I can't guarantee. I'm just interested in seeing what other solutions there might be to this problem. Thanks in advance :)

• Regular Expressions - Match all alphanumeric characters except individual numbers

  - by imaginonic

  I would like to create a RegEx to match only english alphanumeric characters but ignore (or discard) isolated numbers in Ruby (and if possible in JS too). Examples: 1) I would like the following to be matched: 4chan 9gag test91323432 asf5asdfaf35edfdfad afafaffe But not: 92342424 343424 34432 and so on.. The above is exactly what I would want. 2) However, I would be really thankful if someone could also include French letters like: é ë ê (These are just few examples of many) 1) is my priority, it's totally okay if 2) is impossible or difficult to implement. Sorry, my regex skills aren't that great (hence this question!) Thank you.

• What is Restful Routing?

  - by John Baker

  I have been searching pretty hard for info out on the net to explain exactly what Restful routing is but I haven't had any success. There are a lot of resources but not a who lot make sense to me. I'm familiar with Ruby On Rails's routing system and well as how Code Igniter and PhpCake route things but is there more to it than having a centralized location where you give out routes based on a directory structure? Like this: controller/action/id/ Admin/editUser/22 I'd appreciate any help with this, it's had me baffled for months. I just thought of putting it on SO. Thanks

• respond_to? and protected methods

  - by mlomnicki

  It may not be so obvious how respond_to? works in ruby. Consider that: class A def public_method end protected def protected_method end private def private_method end end obj = A.new obj.respond_to?(:public_method) # true - that's pretty obvious obj.respond_to?(:private_method) # false - as expected obj.respond_to?(:protected_method) # true - WTF? So if 'obj' responds to protected_method we should expect obj.protected_method not to raise an exception, shouldn't we? ...but it raises obviously Documentation points that calling respond_to? with 2nd argument set to true check private method as well obj.respond_to?(:private_method, true) # true And that's far more reasonable So the question is how to check if object responds to public method only? Is there a solution better than that? obj.methods.include?(:public_method) # true obj.methods.include?(:protected_method) # false

• One configuration per domain name on the same application. How to easily access config values from m

  - by Aymeric

  Hi, I run a Ruby on Rails website that have multiple domain names. I have a "Website" table in the database that stores the configuration values related to each domain name: Website - domain - name - tagline - admin_email - etc... At the moment, I load the website object at the start of each request (before_filter) in my ApplicationController: @website = Website.find_by_domain(request.host) The problem is when I need to access the @website object from my models methods. I would like to avoid to have to pass @website everywhere. The best solution would be to have something similar to APP_CONFIG but per domain name. def sample_model_property - - "#{@website.name} is a great website!" end How would you do it?

• inheriting scope from a has_many relationship

  - by hb922

  I am using ruby on rails 3.1 and have 2 models, an event and a group. Each event has_many groups, but has to have at least one "master" group, where the column :is_master = true Class Group < ActiveRecord::Base has_many :users belongs_to :event scope :master, where (:is_master => true) end Class Event< ActiveRecord::Base has_many :groups def master_group groups.master end end I want to be able to default all properties of the master group to the event, so for example, event.users.count should be the same as event.master_group.users.count. Is there any way to do something like this? Can I do a has_many :through = master_group? Am I approaching this the wrong way? Thanks!

• How to handle recursive parent/child problems like this?

  - by lsdude

  In web dev I come across these problems a lot. For example, we have a giant list of URLs that are in this format: /businesses /businesses/food /businesses/food/wendys /businesses/food/wendys/chili /businesses/food/wendys/fries /businesses/food/wendys/chicken-nuggets /businesses/pharmacy/cvs /businesses/pharmacy/cvs/toothpaste /businesses/pharmacy/cvs/toothpaste/brand ... and then we need to output each one, where the parent category is in h1 tags, the child is in h2 tags, and the children of that are in h3 tags. I can handle this but I feel my code is messy. I'm sure there is a design pattern I can use? Langs are ruby/php usually. how would you handle this?

• strange characters at beginning of file

  - by luca

  there are strange characters at the beginning of a file I'm editing (using textmate..) I don't know when they appeared, they're invisible in textmate but my script that reads the file goes crazy.. this is the first few chars in the file (as seen with od command): 0000000 177377 000120 000105 000117 000120 000114 000105 000072 the first 2 shouldn't be there I think.. maybe they were caused by some strange dropbox sync? Or something else.. but they tend to reappear (I don't yet know when..) My question: what is that 177377 and a simple way to remove it in my ruby script? thanks

• Model's method not being recognized when called

  - by Brian Roisentul

  I'm using ruby on rails 2.3.2 and also using the acts_as_taggable_on puglin. That generated me two db tables: tags and taggings. As I didn't need anything more from those, I didn't create a Tag model, for example. Now the project is more mature, I need to create some methods for tags, so I created a Tag model with some methods in it. The model looks something like this: class Tag < ActiveRecord::Base def self.get_parent parent = Tag.find(self.parent_id) return parent end end When I call it from a controller, it won't find the method. This is the code: tag = Tag.find(tag_id) the_parent = tag.get_parent This will throw an error saying: undefined method `get_parent' for #<Tag id: 13, name: "Historia", parent_id: 12> I don't know what's wrong. Any help will be appreciated.

• Converting a 16 bit tiff file to something viewable online?

  - by msandbot

  I need to take a 16 bit .tiff file and make it viewable on my website. To even view .tiff files many browsers require plugins. I found a software that could convert them to .jpg files but I was wondering if there is a way to do this independently. I am making my website using Ruby on Rails. I must be able to do the conversion from the website because the whole point of the website is to upload large folders of .tiff files and display them in an online slideshow. Any help would be appreciated. Thanks!

• What are the design patterns for HTML and CSS ?

  - by IHawk

  I know that is a very embracing question, but I have just started with Ruby on Rails, and still have a long way with CSS and HTML. There are lots of books about CSS and HTML patterns, but I would like to know what is really applied to actual webpages. For example, what's the best way of doing a simple webpage with a lateral menu, a logo on the top, and some text below? Ok, it seems stupid, but there's lot of ways of doing that, or not ? So, how can I learn this patterns and what are the real patterns ? Would appreciate suggestions of books, articles, etc.
