• Why does Rails screw up timezones when I am editing a resource?

  - by DJTripleThreat

  Steps to produce this: prompt>rails test_app prompt>cd test_app prompt>script/generate scaffold date_test my_date:datetime prompt>rake db:migrate now edit your app/views/date_tests/edit.html.erb: <h1>Editing date_test</h1> <% form_for(@date_test) do |f| %> <%= f.error_messages %> <p> RIGHT!<br/> <%= text_field_tag @date_test, f.object.my_date %> </p> <p> WRONG!<br /> <%= f.text_field :my_date %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> <%= link_to 'Show', @date_test %> | <%= link_to 'Back', date_tests_path %> now edit your config/environment.rb: #add this config.time_zone = 'Central Time (US & Canada)' This recreates the problem I am having in my actual app. The problem with my app is that I'm storing a date in a hidden field and rendering a "user friendly" version. Creating a resource works fine but as soon as I try to edit it the time changes (it adds the difference between my current time zone configuration and UTC). go to http://localhost:3000/date_tests/new and save the time then go to reedit it and you will have two different representations of the date/time one which will save incorrectly and the other that will.

• How to implement a tagging plugin for jQuery

  - by anxiety

  Goal: To implement a jQuery plugin for my rails app (or write one myself, if necessary) that creates a "box" around text after a delimiter is typed. Example: With tagging on SO, the user begins typing a tag, then selects one from the drop-down list provided. The input field recognizes that a tag has been selected, puts a space and then is ready for the next tag. Similarly, I am attempting to use this plugin to put a box around the previously entered tag before moving to to accept the next tag/input. The instructions in the README.txt seem simple enough, however I have been receiving a $(".tagbox").tagbox is not a function error when debugging my app with firebug. Here is what I have in my application.js: $(document).ready( function(){ $('.tagbox').tagbox({ separator: /\[,]/, // specifying comma separation for <code>tags</code> }); }); And here is my _form.html.erb: <% form_for @tag do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= text_field :tag, :name, { :method => :get, :class => "tagbox" } %> </p> <p><%= f.submit "Submit" %></p> <% end %> I have omitted some other code (namely the implementation of an autocomplete plugin) existing within my _form.html.erb and application.js for sake of readability. The inclusion or exclusion of this omitted code does not affect the performance of this plugin. I have included all of the necessary files for the tagbox plugin (as well as application.js after all other included JS files) within the javascript_include_tag in my application.html.erb file. I'm pretty much confused as to why I'd be getting this "not a function" error when jquery.tagbox.js clearly defines the function and is included in the head of my html page in question. I've been struggling with this plugin for longer than I'd like to admit, so any help would really be appreciated. And, of course, I'm open to any other plugins or from-scratch suggestions you may have in mind.. This tagbox plugin does not seem to have a wealth of documentation or any currently working examples. Also to note, I'm trying to avoid using jrails. Thanks for your time

• Rails (pagination and tags)

  - by Vitaly

  Hey, I stumbled upon a problem of how to mix both acts_as_taggable (on steroids) and will_paginate gems. What I found on this problem is this: http://www.mckinneystation.com/2007/08/20/pagination-with-acts_as_taggable_on_steroids-acts_as_ferret-and-will_paginate/ But it's dated of 2007, may be there's something more recent? And also could you explain in details what should I do to make that fix work?

• Nokogiri changing custom elements

  - by dagda1

  Hi, I have sample html that I have marked up with some special tags that will be used by a different program, an example of the html is below. You should note the <START:organization>..<END> elements. <html> <head/> <body> <ul> <li> <START:organization> Advanced Integrated Pest Management <END> </li> <li> <START:organization> American Bakers Association <END> </li> </ul> </body> </html> I wanted to use nokogiri to preprocess the html to easily remove irrelevant tags like <script>. I created the following extension to the nokogiri document class: module Nokogiri module HTML class Document def prepare_html xpath("//script").remove to_html.remove_new_lines end end end end The problem is that nokogiri is changing the <START:organization> element to <organization>. Is there anyway that I can preserve the htnl to maintain my custom markup tags? Thanks Paul

• routing problem with startpage in rails3

  - by DannyRe

  Hey, I deleted the Index.html in my /public/ folder. I added a "application" folder in my views. In it I put a new index.html.erb. This I want to be my startpage/homepage. In my new "index.html.erb" I set: link_to 'sign in', {:controller => 'devise/sessions', :action => 'new'} But it redirects me to the "application#index". I set root :to => "application#index How can I set this to route it to "posts#index" after I sign in, for example? Is there a chance to use .erb oder .haml in my /public/index.html? Many thanks!!

• Using named_scope with counts of child models

  - by Joe Cairns

  Hi, I have a simple parent object having many children. I'm trying to figure out how to use a named scope for bringing back just parents with specific numbers of children. Is this possible? class Foo < ActiveRecord::Base has_many :bars named_scope :with_no_bars, ... # count of bars == 0 named_scope :with_one_bar, ... # count of bars == 1 named_scope :with_more_than_one_bar, ... # count of bars > 1 end class Bar < ActiveRecord::Base belongs_to :foo end I'm hoping to do something like Foo.with_one_bar I could write methods on the parent class for something like this, but I'd rather have the power of the named scope

• Help getting ActiveScaffold to work properly

  - by x3ro

  Hey there I was curious about the ActiveScaffold Rails plugin, but somehow I can't get it to work properly. I've followed the steps which are described on http://activescaffold.com/tutorials/ . The table and everything shows up and when I click on "Create new", the dialog pops up. However, when I fill out the form and click "Create", I just get "500 Internal server error". In the server log, it says "NameError (wrong constant name ###):", with ### being what I entered in the first form field. If I don't enter anything in the form, it says "NoMethodError (undefined method `new_record?' for #):"... So what am I doing wrong here? Thanks in advance for your help :)

• Is there a way to make the flash[:notice] appear above, or before, the flash[:error] ?

  - by GoodGets

  So, I'd like to be able to display both a flash[:notice] and a flash[:error] on the same action, but I'd like for the :notice to always be displayed above (or before) the error. Is there a way to do this? In my controller, I thought I could just code the flash[:error] before the flash[:notice], so that rails will display it correctly, and it does a vast majority of the time. But every now and then they are randomly switched, and I can't seem to figure out why. So, how can I ensure that a flash[:notice] is always displayed above an :error ?

• Array::include? on ActiveRecord collection not calling op== ?

  - by tribalvibes

  Given a collection of named Foos from ActiveRecord, why does Array.include? not seem to call Foo.== but yet index does? class Foo < ActiveRecord::Base def ==(s) self.name == s end end class Bar < ActiveRecord::Base has_many :foos end bar.foos << Foo.new( :name = 'hmm' ) bar.foos.all.include?('hmm') # does select all from db every time = true bar.foos.include?('hmm') # does not go to db, but does not find the Foo! = false bar.foos.index('hmm') # does not go to db, but does find the Foo[0] ! = 0 bar.foos.index('eh') # no such object = nil I understand shallow about the proxies, but (without a detour into the AR source) why is index seemingly behaving correctly but include? is not !? Is this a bug in the proxy behavior, and/or is this behavior documented somewhere ? Thanks.

• Adding RESTful route to Rails app

  - by macek

  I'm reading these two pages resources Adding more RESTful actions The Rails Guides page shows map.resources :photos, :new => { :upload => :post } And its corresponding URL /photos/upload This looks wonderful. My routes.rb shows this map.resources :users, :new => { :signup => :get, :register => :post } When I do: [~/my_app]$ rake routes I see the two new routes added signup_new_user GET /users/new/signup(.:format) register_new_user POST /users/new/register(.:format) Note the inclusion of /new! I don't want that. I just want /users/signup and /users/register (as described in the Rails Routing Guide). Any help?

• Saving an active record, in what order are the associated objects saved?

  - by Bryan

  In rails, when saving an active_record object, its associated objects will be saved as well. But has_one and has_many association have different order in saving objects. I have three simplified models: class Team < ActiveRecord::Base has_many :players has_one :coach end class Player < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end class Coach < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end I expected that when team.save is called, team should be saved before its associated coach and players. I use the following code to test these models: t = Team.new team.coach = Coach.new team.save! team.save! returns true. But in another test: t = Team.new team.players << Player.new team.save! team.save! gives the following error: > ActiveRecord::RecordInvalid: > Validation failed: Players is invalid I figured out that team.save! saves objects in the following order: 1) players, 2) team, and 3) coach. This is why I got the error: When a player is saved, team doesn't yet have a id, so validates_presence_of :team_id fails in player. Can someone explain to me why objects are saved in this order? This seems not logical to me.

• duplicate rows in join table with has_many => through and accepts_nested_attributes_for

  An event has many artists, and an artist has many events. The join of an artist and an event is called a performance. I want to add artists to an event.

• Does it make sense to fragment cache static partials

  - by ash34

  Hi, I have my views and layouts split into multiple partials, some of them are static partials i.e, no data from the database being displayed here. Does it make sense to cache these to prevent the erb templating system from generating the html each time or it only makes sense to cache in situations where something needs to be retrieved from the db each time. thanks, ash

• Precompile assets for a rails engine

  - by Peter Ehrlich

  In a standard app, I have this line in my production.rb, which creates endpoints for non-default precompiled assets: config.assets.precompile += %w( mobile.css ) My rails engine is a standard Sinatra app. It has its own assets. When on development, these assets are served fine, presumably the web requests are handled by rails and sprockets. On production I'm getting 404s on the assets, and think I have to manually tell sprockets to provide the files. How can this be done without tightly linking? It isin't evident how to set up env-specific initializers for engines. Is this done? Not only, for example, is config/development.rb within the engine not loaded, but there's no way to get the application class itself without knowing its name, in order to modify configuration. And even if there was, it seems that having any engine able to reconfigure the main app would be very bad idea. So maybe its better to let assets handling be done by sinatra itself? Or another instance of sprockets for the engine? How do other engines handle this?

• are fixtures loaded when using the sql dump to create a test database

  - by Josh Moore

  Because of some non standard table creation options I am forced to use the sql dump instead of the standard schema.rb (i.e. I have uncommented this line in the environment.rb config.active_record.schema_format = :sql). I have noticed that when I use the sql dump that my fixtures do not seem to be loaded into the database. Some data is loaded into it but, I am not sure where it is coming from. Is this normal? and if it is normal can anybody tell me where this other data is coming from?

• Active Record like functionality on array instance variable

  - by rube_noob

  I would like to write a module that provides active record like functionality on an array instance variable. Examples of its use would be x = Container.new x.include(ContainerModule) x.elements << Element.new x.elements.find id module ContainerModule def initialize(*args) @elements = [] class << @elements def <<(element) #do something with the Container... super(element) end def find(id) #find an element using the Container's id self #=> #<Array..> but I need #<Container..> end end super(*args) end end The problem is that I need the Container object within these methods. Any reference to self will return the Array, not the Container object. Is there any way to do this? Thanks!

• Yet another Rails routing question

  - by danhere

  I can't seem to grasp the Rails routing just yet. I want to be able to link the site to, for example, ...com/store/xbox360/Mass Effect 2 (which is /store(my controller)/:system/:title). I have the database entries that include the :system and :title variables (?). How would I route these to show up and filter these entries? Or is this something I need to set up in the controller? I'm lost. Thanks so much for your help.

• disabling transactional fixtures in Rspec has no effect

  - by Dia

  Due to a legacy database I'm using, I'm stuck with MySQL using MyISAM, which means my tables don't support transactions. This is causing the tests to fail, since table data generated (I'm using factory_girl for fixtures) by the tests are not reverted for each scenario. I discovered that Rspec exposes the config.use_transactional_fixtures config setting in spec_helper.rb. which is set to true by default. When I set it to false, I don't see any effect on my tests; they still fail due to duplicate records. Isn't that setting supposed to automatically unroll any changes made to the DB? Or am I supposed to do that manually?

• Validate HAML from ActiveRecord: scope/controller/helpers for link_to etc?

  - by Chris Boyle

  I like HAML. So much, in fact, that in my first Rails app, which is the usual blog/CMS thing, I want to render the body of my Page model using HAML. So here is app/views/pages/_body.html.haml: .entry-content= Haml::Engine.new(body, :format => :html5).render ...and it works (yay, recursion). What I'd like to do is validate the HAML in the body when creating or updating a Page. I can almost do that, but I'm stuck on the scope argument to render. I have this in app/models/page.rb: validates_each :body do |record, attr, value| begin Haml::Engine.new(value, :format => :html5).render(record) rescue Exception => e record.errors.add attr, "line #{(e.respond_to? :line) && e.line || 'unknown'}: #{e.message}" end end You can see I'm passing record, which is a Page, but even that doesn't have a controller, and in particular doesn't have any helpers like link_to, so as soon as a Page uses any of that it's going to fail to validate even when it would actually render just fine. So I guess I need a controller as scope for this, but accessing that from here in the model (where the validator is) is a big MVC no-no, and as such I don't think Rails gives me a way to do it. (I mean, I suppose I could stash a controller in some singleton somewhere or something, but... excuse me while I throw up.) What's the least ugly way to properly validate HAML in an ActiveRecord validator?
