• Rails: What's the suggested approach to retrieve xml from an outside source

  - by Syrahn

  Rails newbie (though long time programmer) here. I'm writing an test app that retrieves data from several outside sources (think Twitter, RSS feeds, etc.) and under certain circumstances, it stores that data in a db (or presents it to the user). The data model and the views are trivial. What I'm having difficulty with is making the actual xml HTTP call to the outside source and deserialize the xml response so I can query/use it in my controller/helper. What library/gem should I use to accomplish this? I tried looking this up around the net, but only came up with some article from 2006 which, knowing how fast Rails has developed, might well be completely deprecated. Your help is much appreciated.

  - by blackpond

  I want to have a select menu to change a field on a Customer dynamically, I've never used Jquery with a select menu, and I'm having problems.

• MIgrations and Rspec

  - by pablorc

  Hi, I'm developing a Rails application with Rspec for unit testing. Weeks ago, Rspec used to migrate the database to the last version automatically when executing 'rake spec', but now it doesn't do it automatically, I have to implement everything for myself. This happens in test environment, because my development data doesn't desappear. Is my fault? I didn't change anything, I think :) Thanks in advance.

• Generating the input id with an ActiveRecord model

  - by swilliams

  How do you generate an input's id attribute, given a model? For example, if I have a model of Person with a first_name attribute, the form helper prints out a textbox with this html: <input type="text" id="person_first_name" /> How can I generate that person_first_name from some other place in the code (like in a controller or some place)?

• Lightbox getting open multiple time on enter.

  - by Salil

  Hi All, I am going through a weird problem while using lightbox . Where ever the new light box is used user is able to open the same light box on same page number of time. For e.g Using tab button go to `Lightbox link`. Press enter --> Light box will open. Press enter --> second light box open below the previous one. and so on....... The problem is occurred when I use tab and entered on the link my focus is not getting changed from the link and so user is able to open multiple lightbox on clicking enter.

• ActiveRecord date format

  - by Mongus Pong

  I've run into a spot of bother with date formats in our Rails application. I have a date field in our view which I want to be formatted as dd/mm/yy. This is how the user will expect to enter their dates, and the datepicker control uses this format. However, Active Record seems to be expecting mm/dd/yy. If I enter 01/03/2010, this gets put in as 03 January 2010. If I enter 25/03/2010, this gets put in a null. How do I get ActiveRecord to expect Her Majesties date format?

• About presenter pattern in rails. is a better way to do it?

  - by Totty

  I have in my model: def presenter @presenter ||= ProfilePresenter.new(self) @presenter end The ProfilePresenter is a class that has methods like, get_link(), get_img_url(size), get_sex(), get_relationship_status() and other methods that have not to do with the model, not even with the controller but is used multiple times in the view. So now i use them by doing this: Profile.presenter.get_link # or Profile.presenter.get_img_url('thumb') # returns the path of the image. is not used to make a db query

• Rails: bi-directional has_many :through relationship

  - by Chris

  I have three models in a Rails application: Game represents an instance of a game being played. Player represents an instance of a participant in a game. User represents a registered person who can participate in games. Each Game can have many Players, and each User can have many Players (a single person can participate in multiple games at once); but each Player is in precisely one Game, and represents precisely one User. Hence, my relationships are as follows at present. class Game has_many :players end class User has_many :players end class Player belongs_to :game belongs_to :user end ... where naturally the players table has game_id and user_id columns, but games and users have no foreign keys. I would also like to represent the fact that each Game has many Users playing in it; and each User has many Games in which they are playing. How do I do this? Is it enough to add class Game has_many :users, :through => :players end class User has_many :games, :through => :players end

• How do I sort an activerecord result set on a i18n translated column?

  - by PlanetMaster

  Hi, I have the following line in a view: <%= f.select(:province_id, options_from_collection_for_select(Province.find(:all, :conditions => { :country_id => @property.country_id }, :order => "provinces.name ASC"), :id, :name) %> In the province model I have the following: def name I18n.t(super) end Problem is that the :name field is translated (through the province model) and that the ordering is done by activerecord on the english name. The non-english result set can be wrongly sorted this way. We have a province in Belgium called 'Oost-Vlaanderen'. In english that is 'East-Flanders". Not good for sorting:) I need something like this, but it does not work: <%= f.select(:province_id, options_from_collection_for_select(Province.find(:all, :conditions => { :country_id => @property.country_id }, :order => "provinces.I18n.t(name) ASC"), :id, :name) %> What would be the best approach to solve this? As you may have noticed, my coding knowledge is very limited, sorry for that.

• rails eval code

  - by xpepermint

  Hey. I have to do a coll inside my model like this: import = Import.find(id) status = User.find(import.user_id).{XXX}.import(import.file.path) Notice a {XXX} which should be replaced by a dinamic variable of a submodel. Model User has_many groups, clients and products. In translation this would be status = User.find(import.user_id).groups.import(import.file.path) status = User.find(import.user_id).clients.import(import.file.path) status = User.find(import.user_id).products.import(import.file.path) I was thinking of import = Import.find(id) status = eval("User.find(#{import.user_id}).#{import.model}").import(import.file.path) but this gives me an error 'TypeError: can't convert nil into String'. Please tell me how would you fix that. Thx!

• In rails whats the best way to get the site that a user came from? I am getting conflicting info.

  - by kidbrax

  If i enter a url directly into the address bar of the browser, i get the following results: logger.debug ENV['HTTP_REFERER'] // => logger.debug request.referrer // => / So the first one gives me a blank result which is what I expected but the second gives me the root? Is this correct? It seems from the docs (http://api.rubyonrails.org/classes/ActionController/AbstractRequest.html#M000478) that they should return the same thing. And secondly, why does it return the root, if there was no referrer.

• Rails Routes Mappings

  - by rdasxy

  I'm a rails newbie, and I have a controller called resource_links that I've mapped to resources: resources :resources, :as => :resource_links, :controller => :resource_links And this works (basically /resources works as /resource_links). However, trying to go to /resources/tags does not work. To get around this, I added more mappings as: match 'resource_links/tag/:tag(.:format)' => 'resource_links#tag', :via => :get, :as => 'resource_links_tagged', :constraints => {:tag => /.*/} match 'resource_links/tags' => 'resource_links#tags', :via => :get, :as => 'resource_links_tags' Is there any way I can get /resources/tags to be mapped to /resource_links/tag?

• Multi-model form problem

  - by raphael_turtle

  (I'm just learning rails so....) I have a photo model and a gallery model, habtm associations and a join table. I'm making a photo gallery. The gallery page has a title field and description field. User creates gallery title, then goes to the photo page and checkboxes each image they want in that gallery. I get the error "undefined method `to_i' for ["1", {"title"="1"}]:Array" when trying to save/update a photo with a gallery title(with the checkbox) <% form_for @photo, :html => {:multipart => true } do |f| %> <%= f.error_messages %> <p> <%= f.label :title %> <%= f.text_field :title %> </p> <p> <%= f.label :description %> <%= f.text_area :description %> </p> <p> <%= f.label :image %> <%= f.file_field :image %> </p> <% for gallery in @photo.galleries %> <% fields_for "painting[gallery_attributes][]", gallery do |g| %> <div> <%= g.check_box :title %> <%= gallery.title %> </div> <% end %> <% end %> <p><%= submit_tag 'Update' %></p> <% end %> How much of this is horribly wrong? Can someone point me in the right direction?, I can't find any tutorials relating to this for 2.3 and above.

• Finding records when using has_many through associations

  - by winter sun

  I have two models, Worker and Project, and they are connected with has_many through association. I manage to find all the projects which are related to a specific worker by writing the following code: worker=Worker.find_by_id("some_id") worker.projects but I want the projects that I get to be only active projects (in the project model I have a status field) I tried to do something like worker.projects(:status_id=>'active') but it didn’t work for me. Can somebody tell me how I can do this?

• How can I have a single helper work on different models passed to it?

  - by Angela

  I am probably going to need to refactor in two steps since I'm still developing the project and learning the use-cases as I go along since it is to scratch my own itch. I have three models: Letters, Calls, Emails. They have some similarilty, but I anticipate they also will have some different attributes as you can tell from their description. Ideally I could refactor them as Events, with a type as Letters, Calls, Emails, but didn't know how to extend subclasses. My immediate need is this: I have a helper which checks on the status of whether an email (for example) was sent to a specific contact: def show_email_status(contact, email) @contact_email = ContactEmail.find(:first, :conditions => {:contact_id => contact.id, :email_id => email.id }) if ! @contact_email.nil? return @contact_email.status end end I realized that I, of course, want to know the status for whether a call was made to a contact as well, so I wrote: def show_call_status(contact, call) @contact_call = ContactCall.find(:first, :conditions => {:contact_id => contact.id, :call_id => call.id }) if ! @contact_call.nil? return @contact_call.status end end I would love to be able to just have a single helper show_status where I can say show_status(contact,call) or show_status(contact,email) and it would know whether to look for the object @contact_call or @contact_email. Yes, it would be easier if it were just @contact_event, but I want to do a small refactoring while I get the program up and running, and this would make the ability to do a history for a given contact much easier. Thanks!

• how do you group select_tag and text_field_tag?

  - by Eytan

  I'm trying to build a form where a user can select an existing category, or define their own. My form looks something like this... <%= f.select :category, category_options, prompt: "Select"> <%= f.text_field :category %> However, this UI is confusing. The user can select something in the select box, and type in a custom category. In this case, the final result is not obvious. Do you guys have any recommendations on how to handle this situation?

• Rails 2.3.5: How to handle this type of validation

  - by randombits

  The use case is simple. I allow users to enter in an expiration field which needs to be between 1 and 15 into a form. The model takes that number and converts it into a datetime (such as adding 15 days from today) and stores it in the database. What's the correct way to actually validate that though? Do I validate against the datetime format that gets persisted in the database or the select box (1..15) that the user gets to pick through the form? I want to be able to validate that the user is putting in 1..15.. How is this done with ActiveRecord validation in Rails 2.3.5?

• No such file to load, Model/Lib naming conflict?

  - by Tom

  I'm working on a Rails application. I have a Module called Animals. Inside this Module is a Class with the same name as one of my Models (Dog). show_animal action: def show_animal require 'Animals/Bear.rb' #Works require 'Animals/Dog.rb' #Fails end So the first require definitely works, the seconds fails. MissingSourceFile (no such file to load -- Animals/Dog.rb): I noticed that Dog.rb is the same file name as one of my models, is that what's causing this? I'm using Webrick.

• rails 3.1 partial_updates doesn't seem to work with password

  - by user1306769

  i have a user model with a password attribute, which gets saved as password_digest. What i want to do is have the edit user page and the edit password page separated, so that the admin doesn't need to input the password everytime he needs to change something else. For this i have made an extra action / view. My problem is that when i update the user info, i get password validation errors even though i have no password field in the form. Which leads me to the conclusion that partial_updates isn't working with the password attribute (as i have already tested in the console that it is enabled, and it is) Is this me doing something wrong, or should i approach this differently?

• Rails active record association problem

  - by Harm de Wit

  Hello, I'm new at active record association in rails so i don't know how to solve the following problem: I have a tables called 'meetings' and 'users'. I have correctly associated these two together by making a table 'participants' and set the following association statements: class Meeting < ActiveRecord::Base has_many :participants, :dependent => :destroy has_many :users, :through => :participants and class Participant < ActiveRecord::Base belongs_to :meeting belongs_to :user and the last model class User < ActiveRecord::Base has_many :participants, :dependent => :destroy At this point all is going well and i can access the user values of attending participants of a specific meeting by calling @meeting.users in the normal meetingshow.html.erb view. Now i want to make connections between these participants. Therefore i made a model called 'connections' and created the columns of 'meeting_id', 'user_id' and 'connected_user_id'. So these connections are kinda like friendships within a certain meeting. My question is: How can i set the model associations so i can easily control these connections? I would like to see a solution where i could use @meeting.users.each do |user| user.connections.each do |c| <do something> end end I tried this by changing the model of meetings to this: class Meeting < ActiveRecord::Base has_many :participants, :dependent => :destroy has_many :users, :through => :participants has_many :connections, :dependent => :destroy has_many :participating_user_connections, :through => :connections, :source => :user Please, does anyone have a solution/tip how to solve this the rails way?
