  • Rails populate edit form for non-column attributes

    - by Rabbott
    I have the following form: <% form_for(@account, :url => admin_accounts_path) do |f| %> <%= f.error_messages %> <%= render :partial => 'form', :locals => {:f => f} %> <h2>Account Details</h2> <% f.fields_for :customer do |customer_fields| %> <p> <%= customer_fields.label :company %><br /> <%= customer_fields.text_field :company %> </p> <p> <%= customer_fields.label :first_name %><br /> <%= customer_fields.text_field :first_name %> </p> <p> <%= customer_fields.label :last_name %><br /> <%= customer_fields.text_field :last_name %> </p> <p> <%= customer_fields.label :phone %><br /> <%= customer_fields.text_field :phone %> </p> <% end %> <p> <%= f.submit 'Create' %> </p> <% end %> As well as attr_accessor :customer And I have a before_create method for the account model which does not store the customer_fields, but instead uses them to submit data to an API.. The only thing I store are in the form partial.. The problem I'm running into is that when a validation error gets thrown, the page renders the new action (expected) but none of the non-column attributes within the Account Detail form will show? Any ideas as to how I can change this code around a bit to make this work me?? This same solution may be the help I need for the edit form, I have a getter for the data which it asks the API for, but without place a :value = "asdf" within each text box, it doesn't populate the fields either..

  • From Sinatra Base object. Get port of application including the base object

    - by Poul
    I have a Sinatra::Base object that I would like to include in all of my web apps. In that base class I have the configure method which is called on start-up. I would like that configure code to 'register' that service with a centralized database. The information that needs to be sent when registering is the information on how to contact this web-service... things like host and port. I then plan on having a monitoring service that will spin over all registered services and occasionally ping them to make sure they are still up and running. In the configure method I am having trouble getting the port information. The 'self.settings.port' variable doesn't seem to work in this method. a) any ideas on how to get the port? I have the host. b) is there a sinatra plug-in that already does something like this so I don't have to write it myself? :-) //in my Sinatra::Base code. lets call it register_me.rb RegisterMe < Sinatra::Base configure do //save host and port information to database end get '/check_status' //return status end //in my web service code require register_me //at this point, sinatra will initialize the RegisterMe object and call configure post ('/blah') //example of a method for this particular web service end

  • Rails: Multiple "types" of one model through related models?

    - by neezer
    I have a User model in my app, which I would like to store basic user information, such as email address, first and last name, phone number, etc. I also have many different types of users in my system, including sales agents, clients, guests, etc. I would like to be able to use the same User model as a base for all the others, so that I don't have to include all the fields for all the related roles in one model, and can delegate as necessary (cutting down on duplicate database fields as well as providing easy mobility from changing one user of one type to another). So, what I'd like is this: User -- first name -- last name -- email --> is a "client", so ---- client field 1 ---- client field 2 ---- client field 3 User -- first name -- last name -- email --> is a "sales agent", so ---- sales agent field 1 ---- sales agent field 2 ---- sales agent field 3 and so on... In addition, when a new user signs up, I want that new user to automatically be assigned the role of "client" (I'm talking about database fields here, not authorization, though I hope to eventually include this logic in my user authorization as well). I have a multi-step signup wizard I'm trying to build with wizardly. The first step is easy, since I'm simply calling the fields included in the base User model (such as first_name and email), but the second step is trickier since it should be calling in fields from the associated model (like--per my example above--the model client with fields client_field_1 or client_field_2, as if those fields were part of User). Does that make sense? Let me know if that wasn't clear at all, and I'll try to explain it in a different way. Can anyone help me with this? How would I do this?

  • Rails: Routing to a different controller based on request format

    - by Jimmy Cuadra
    I'm writing an app where I want all requests for HTML to be handled by the same controller action. I have some other routes that are JSON-specific. Here's what my routes look like: Blog::Application.routes.draw do constraints format: :json do resources :posts end match "(*path)" => "web#index" end The problem is that constraints is being interpreted as "this route only works with the specified format" rather than "skip this route and try the next one if the request is not in the specified format." In other words, navigating to /posts in the browser gives me a 406 Not Acceptable because the URL is constrained to the JSON format. Instead, I want it to fall through to web#index if the request is for HTML, and hit the resourceful route if the request is for JSON. How can this be achieved? (Using Rails 3.2.9.)

  • How long can rails keep Ajax open

    - by Alexey
    My application is suppose to constantly update the page without any user interaction. The criteria is that the page just has to be there, as an extra window on the monitor so the user can see the information get updated real time. I'm using the Ajax in jQuery with Rails, and my question is - how long will the .erb page keep Ajax open? Will there be a point where I have to refresh the page or re-initialize? Or will that won't be a problem at all?

  • Rails has_and_belongs_to_many join across 3 tables

    - by Birdman
    I have a three models: listing, category, and site. There is a many to many relationship between listing and site and there is a many to many relationship between listing and category. A listing thus belongs to one or more sites and one or more categories (a listing can appear on multiple sites and multiple categories). Given a site id and a category id, I want a set of all the listings. I understand how to get the listings from a site id (listings = site.listings) and how to get the listings from a category id (listings = category.listings), but how do I get the triple join of the set of listings from both a site id and category id? The sql would look something like (sit_id and cat_id are input): select l.name from listings l, categories_listings cl, listings_sites, ls where cl.category_id = cat_id and ls.site_id = sit_id and cl.listing_id = l.id and ls.listing_id = l.id Thanks in advance

    - by El - Key

  • Why MyModel.all works in Rails ?

    - by AntonAL
    Hi, i don't understand this little thing: Suppose, we have "Person" model class Person < ActiveRecord::Base end Why Person.all works ? Person.all.each { |p| do_something } This syntax tells us, that we have Person class-object instanciated somewhere ? Or is it some convention over configuration case ?

  • What to do with missing fields in sunspot-rails?

    - by chrismealy
    I'm using sunspot/rails version 2. It's working great, but I can't figure out how to handle missing fields. If I don't have latitude and longitude this code will map it to 0,0 (near Africa): searchable do text :resume, :stored => true text :city, :boost => 5 latlon(:geo) { Sunspot::Util::Coordinates.new(latitude, longitude) } end I tried using two search blocks, each with a different conditional, but sunspot just uses the first searchable block. What I want to happen is for things missing locations to still be searchable, just not by location.

  • Specifying the range of supported Rails versions in a project

    - by Tomas Sedovic
    The config/environment.rb of my rails project contains this line: RAILS_GEM_VERSION = '>= 2.3.2' unless defined? RAILS_GEM_VERSION Which makes sure that only Rails of version 2.3.2 or greater will be used to run this app. Is there a way of specifying both the lower and the upper boundary at the same time? So that it would run, say, only on versions higher than 2.3.1 and lower than 2.3.6?

  • Joining a one-to-many association with a many-to-many association in Rails 3

    - by Maz
    Hi all, I have a many-to-many association between a User class and a Table class. Additionally, i have a one-to-many association between the User and the Table (one User ultimately owns the table). I am trying to access all of the tables which the user may access (essintally joining both associations). Additionally, it would be nice to do this this with named_scope (now scope) Here's what I have so far: class User < ActiveRecord::Base acts_as_authentic attr_accessible :email, :password, :password_confirmation has_many :feedbacks has_many :tables has_many :user_table_permissions has_many :editableTables, :class_name => "Table", :through => :user_table_permissions def allTables editableTables.merge(tables) end end Thanks.

  • Rails 3) Delete, Destory, and Routing

    - by Maximus S
    The problem is the code below <%= button_to t('.delete'), @post, :method => :delete, :class => :destroy %> My Post model has many relations that are dependent on delete. However, the code above will only remove the post, leaving its relations intact. The problem is that methods delete and destroy are different in that method delete doesn't instantiate the object. So I need to use "destroy" instead of "delete" my post. <%= button_to t('.delete'), @post, :method => :destroy %> gives me routing error. No route matches [POST] "/posts/2" <%= button_to t('.delete'), @post, Post.destroy(@post) %> deletes the post without clicking the button. Could anyone help me with this? UPDATE: application.js //= require jquery //= require jquery-ui //= require jquery_ujs //= require bootstrap-modal //= require bootstrap-typeahead //= require_tree . rake routes DELETE (/:locale)/posts/:id(.:format) posts#destroy Post model has_many :tag_links, :dependent => :destroy has_many :tags, :through => :tag_links Tag model has_many :tag_links, :dependent => :destroy has_many :posts, :through => :tag_links Problem: When I delete a post, all the tag_links are destroyed but tags still exist.

  • Rails - Permission denied when try to save uploaded file in windows

    - by logoin
    I'm writing my own file upload in rails. I saw some related questions but it doesn't answer my question. I use File.open ("#{RAILS_ROOT}/public/docs/attachments/#{@file_name}", "wb") {|f| f.write(@temp_file.read)} to write the file on my local machine (OS: Windows XP) instead of saving it in database. I got a Permission denied error on the File.open method. Since I have cygwin installed, I chmod 777 the folder that files should write to and also make sure the file I upload can be read. But I'm still getting the same error. Any ideas? Thanks!

  • Problem with skipping login validation for authlogic

    - by Andrei
    Hi, I want to use email for signing in, and to allow users to have similar names. One way to do this is to rename login/username field to something different. However, I want to do it just by setting up authlogic. I tried the following acts_as_authentic do |c| c.login_field :email c.validate_login_field false c.validate_email_field true end but it still complains that the login already exists. What must be done to avoid username validation without renaming the field?

  • I have the CSS & JS, how do I convert that to erb for my Rails app?

    - by marcamillion
    So I have the foundation of my Rails app, then I went ahead and did the JS and CSS. How do I then take the CSS and JS that I have, and apply it to the app in a 'Rails Way'. i.e. a dynamic way that works nicely. Can you give me some tutorials/articles/resources that I can read up to guide me, please? I have tried the Rails guides, but I find them a bit lacking. Any other good suggestions or tips that might help get me on the right track? Thanks.

  • In Sinatra, best way to serve iPhone layout vs. normal layout?

    - by Doug
    I'm writing a Sinatra app which needs to render different layouts based on whether the user is using an iPhone or a regular browser. I can detect the browser type using Rack-Mobile-Detect but I'm not sure of the best way to tell Sinatra which layout to use. Also, I have a feeling that how I choose to do this may also break page caching. Is that true? Example code: require 'sinatra/base' require 'haml' require 'rack/mobile-detect' class Orca < Sinatra::Base use Rack::MobileDetect helpers do def choose_layout if request.env['X_MOBILE_DEVICE'] == :iPhone # use iPhone layout else # use normal layout end end end before do # should I use a before filter? choose_layout() end get '/' do haml :home # with proper layout end end #Class Orca

  • What to Learn: Rails 1.2.4 -> Rails 3

    - by Saterus
    I've recently convinced my management that our outdated version of Rails is slowing us down enough to warrant an upgrade. The approach we're taking is to start a fresh project with current technology rather than a painful upgrade. Our requirements for the project have changed and this will be much easier. The biggest problem is actually that my knowledge of Rails is out of date. I've dealt only with Rails 1.2.4 while the rest of the world has moved on long ago. What topics have I missed by being buried in my work instead of keeping up with the current Rails fashion? I'm hesitant to dig through blogs at random because I'm not sure how much has changed between the intervening versions of Rails. It's no use to learn Rails 2.1-2.3 specific stuff that is no longer useful for Rails 3.

  • Rails find_or_create by more than one attribute?

    - by tybro0103
    There is a handy dynamic attribute in active-record called find_or_create_by: Model.find_or_create_by_<attribute>(:<attribute> => "") But what if I need to find_or_create by more than one attribute? Say I have a model to handle a M:M relationship between Group and Member called GroupMember. I could have many instances where member_id = 4, but I don't ever want more than once instance where member_id = 4 and group_id = 7. I'm trying to figure out if it's possible to do something like this: GroupMember.find_or_create(:member_id => 4, :group_id => 7) I realize there may be better ways to handle this, but I like the convenience of the idea of find_or_create.

  • Rails Nested Attributes, Relationship for Shared or Common Object

    - by SooDesuNe
    This has to be a common problem, so I'm surprised that Google didn't turn up more answers. I'm working on a rails app that has several different kinds of entities, those entities by need a relation to a different entity. For example: Address: a Model that stores the details of a street address (this is my shared entity) PersonContact: a Model that includes things like home phone, cell phone and email address. This model needs to have an address associated with it DogContact: Obviously, if you want to contact a dog, you have to go to where it lives. So, PersonContact and DogContact should have foreign keys to Address. Even, though they are really the "owning" object of Address. This would be fine, except that accepts_nested_attributes_for is counting on the foreign key being in Address to work correctly. What's the correct strategy to keep the foreign key in Address, but have PersonContact and DogContact be the owning objects?

  • link_to for calling an action, instead of a button_to

    - by Brian Roisentul
    I'd like to call an action with a link_to button without being redirected to another page(I don't want ajax). For you to have an idea, I'm trying to accomplish a sort "link button" in a search page. So, when the link is clicked, the page should be refreshed showing the list ordered as I tell it in the action. If I do the following in my view, it will ask me for a template called as the action, and I don't want it: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> My routes file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' And my controller looks like this(I haven't developed the functionality yet): def search_filter_relevance end Any help on this will be appreciated.

  • How can I reduce the number of loops in this VIEW in Rails when using :collection?

    - by Angela
    I am using the :collection to go through all the Contacts that are part of a given Campaign. But within that Campaign I check for three different Models (each with their own partial). Feels like I am going through the list of Contacts 3x. How can I make this alot leaner? <h2>These are past due:</h2> <% @campaigns.each do |campaign| %> <h3>Campaign: <%= link_to campaign.name, campaign %></h3> <strong>Emails in this Campaign:</strong> <% for email in campaign.emails %> <h4><%= link_to email.title, email %> <%= email.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%> <!--contacts collection--> <!-- render the information for each contact --> <%= render :partial => "contact_email", :collection => @contacts, :locals => {:email => email} %> <% end %> Calls in this Campaign: <% for call in campaign.calls %> <h4><%= link_to call.title, call %> <%= call.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%> <!--contacts collection--> <!-- render the information for each contact --> <%= render :partial => "contact_call", :collection => @contacts, :locals => {:call => call} %> <% end %> Letters in this Campaign: <% for letter in campaign.letters %> <h4><%= link_to letter.title, letter %> <%= letter.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%> <!--contacts collection--> <!-- render the information for each contact --> <%= render :partial => "contact_letter", :collection => @contacts, :locals => {:letter => letter} %> <% end %> <% end %>
