  • Multiple Rails forks with separate designs and layouts

    - by mettadore
    I have a Rails project that is basically a simple web app for a membership-based organization. We've open sourced the code on Github for the web app so that others can use it, but have a licensed design/layout that the original organization is going to use. This layout cannot be open sourced. I was wondering if others have run into the situation where you have an open-source Rails app with a non-OS design. My initial thought is to put app/views in .gitignore, and to have anyone forking the code add their own views directory, perhaps including an app/views_default directory with a web-app-theme layout or something else to get people running. Is this the best option (realizing that there are other files such as JavaScript, CSS, etc that come with the layout that must also be ignored). Does anyone have some good thoughts or pointers on this?

  • Authentication in Rails, where to start?

    - by Victor P
    Hello. Im learning Rails by building apps. I want to make my first authenticated app: users signup, login, do some changes in models they have access to and logout. I did the Google search but it is quite confusing: many plugins, many tutorials. Don't know where to start. Is there a state-of-the-art authentication method for Rails? What do you use in Production to authenticate your users? Any help in this will be helpful. Thanks

  • Best way to associate phone numbers with names

    - by Horace Loeb
    My application stores lots of its users friends' phone numbers. I'd like to allow users to associate names with these phone numbers, but I don't want to make users manually type in names (obviously). I'm curious what the best overall approach is here, as well as the best way to implement it Overall approach-wise, I imagine using Gmail / Yahoo / Windows Live contacts is best (the Facebook API doesn't let you access phone numbers), though the gems I've found for interacting with these contacts APIs (this and this) only give you access to the names and email addresses of each contact.

  • post-install hook for a particular gem

    - by Henry Flower
    Here is what I've googled: http://www.mail-archive.com/[email protected]/msg02168.html Gem.post_install do |installer| puts "!!! #{installer.spec.full_name} INSTALLED !!!" end But where to put this snipped? If I put it in my Rakefile and/or src_of_myproject/lib/rubygems_plugin.rb file, than build the gem, install it--but the expected string is never printed after the installation. I'm totally confused. How to embed the post-install hook into the gem spec? Update: it's getting more interesting. If I put Gem.post_uninstall hook in src_of_myproject/lib/rubygems_plugin.rb--that hook works. Gem.post_uninstall do |uninstaller| puts "!!! #{uninstaller.spec.full_name} UNINSTALLED !!!" end Hm... And wtf is with Gem.post_install?

  • Rails - Preventing users from contributing to website when there score is too low - callback / obser

    - by adam
    A User can add a Sentence directly on my website, via twitter or email. To add a sentence they must have a minimum score. If they don't have the minimum score they cant post the sentence and a warning message is either flashed on the website, sent back to them via twitter or email. So I'm wondering how best to code this check. Im thinking a sentence observer. So far my thoughts are in before_create score_sufficient() - score ok = save - score too low = do not save In the case of too low i need to return some flag so that the calling code can then fire off teh relevant warning. What type of flag should I return? False is too ambiguous as that could refer to validation. I could raise an exception but that doesn't sound right or I could return a symbol? Is this even the right approach? What's the best way to code this?

  • Rails Authlogic Prevent User from Changing their Login/Username

    - by bob
    Hello, I have implemented Authlogic. I believe that this isn't an authlogic specific quesetion. Assume that I have a User model and each User has a column in the database called "login". Upon creating a user, the login column is populated. However, I don't want the user to be able to change their login once they set it. Currently, I have removed the text field in the _form.html.erb file in my views for users. However, it can probably still be accessed through the url right? How can I make it so that once a login is set, it can not be changed at all?

  • How do I stop the scriptaculous blind-down effect from flickering when element has padding?

    - by ro
    Hi all, it seems that when the blind down effect is used on an element with padding it looks a bit awkward. It seems to blind down too far and then jumps back. It's a very subtle thing but is really annoying. I don't have an online example but if you go to the demo on github and give the element a padding-top or bottom with firebug or something you'll see what I mean. http://wiki.github.com/madrobby/scriptaculous/effect-blinddown Anybody found a way to stop it?

  • How do I model a has_many :through and with aggregation in Rails?

    - by Angela
    How do I model having multiple Addresses for a Company and assign a single Address to a Contact? Contacts belong_to a Company. A Company has_many Contacts. A Company also has_many Addresses. And each Contact belongs_to an Address. How do I model this? I have Model/Contacts.rb belong_to :Company belong_to :Address (?) Model/Company.rb has_many :Contacts has_many :Addresses Address is an aggregation of :street1, :street2, :city, :state, :zip so not clear exactly what to do there. So what would I do in my _form so that when I have a contact/new I am able to either default to a main address or select one of the others? If none of them match, adding for a Contact makes that address available to any subsequent contact?

  • How to make ActiveRecord work with legacy partitioned/sharded databases/tables?

    - by Utensil
    thanks for your time first...after all the searching on google, github and here, and got more confused about the big words(partition/shard/fedorate),I figure that I have to describe the specific problem I met and ask around. My company's databases deals with massive users and orders, so we split databases and tables in various ways, some are described below: way database and table name shard by (maybe it's should be called partitioned by?) YZ.X db_YZ.tb_X order serial number last three digits YYYYMMDD. db_YYYYMMDD.tb date YYYYMM.DD db_YYYYMM.tb_ DD date too The basic concept is that databases and tables are seperated acording to a field(not nessissarily the primary key), and there are too many databases and too many tables, so that writing or magically generate one database.yml config for each database and one model for each table isn't possible or at least not the best solution. I looked into drnic's magic solutions, and datafabric, and even the source code of active record, maybe I could use ERB to generate database.yml and do database connection in around filter, and maybe I could use named_scope to dynamically decide the table name for find, but update/create opertions are bounded to "self.class.quoted_table_name" so that I couldn't easily get my problem solved. And even I could generate one model for each table, because its amount is up to 30 most. But this is just not DRY! What I need is a clean solution like the following DSL: class Order < ActiveRecord::Base shard_by :order_serialno do |key| [get_db_config_by(key), #because some or all of the databaes might share the same machine in a regular way or can be configed by a hash of regex, and it can also be a const get_db_name_by(key), get_tb_name_by(key), ] end end Can anybody enlight me? Any help would be greatly appreciated~~~~

  • Storing an encrypted cookie with Rails

    - by J. Pablo Fernández
    I need to store a small piece of data (less than 10 characters) in a cookie in Rails and I need it to be secure. I don't want anybody being able to read that piece of data or injecting their own piece of data (as that would open up the app to many kinds of attacks). I think encrypting the contents of the cookie is the way to go (should I also sign it?). What is the best way to do it? Right now I'm doing this, which looks secure, but many things looked secure to people that knew much more than I about security and then it was discovered it wasn't really secure. I'm saving the secret in this way: encryptor = ActiveSupport::MessageEncryptor.new(Example::Application.config.secret_token) cookies[:secret] = { :value => encryptor.encrypt(secret), :domain => "example.com", :secure => !(Rails.env.test? || Rails.env.development?) } and then I'm reading it like this: encryptor = ActiveSupport::MessageEncryptor.new(Example::Application.config.secret_token) secret = encryptor.decrypt(cookies[:secret]) Is that secure? Any better ways of doing it? Update: I know about Rails' session and how it is secure, both by signing the cookie and by optionally storing the contents of the session server side and I do use the session for what it is for. But my question here is about storing a cookie, a piece of information I do not want in the session but I still need it to be secure.

  • Multiple layouts in rails [Newbie Q]

    - by BriteLite
    Hi. As a newb, I decided to build a "home inventory" application. I am now stuck on how to programmatically select a layout based on what type of item it is when viewing it in a browser. According to my planning, so far I should have created a few models to represent types of items I can find in my home: Furniture, Electronics and Books. class Book < ActiveRecord::Base end class Furniture < ActiveRecord::Base end class Electronic < ActiveRecord::Base end Now the Books model has things like isbn, pages, address, and category. Furniture model has things like color, price, address, and category. Electronics has things like name, voltage, address, and category. Here is where I got confused. I know the property address is going to be the same for all of them. I also know that, I will need to create multiple "layouts" for 3 different types of items to show the different properties of said items with appropriate graphics and stylesheets. But how will I go about deciding which category the item is so I can determine which layout to render. According to me, this is how I will do it: class DisplayController < ApplicationController def display @item = Params[:item] if @item.category = "electronics" render :layout => 'electronics' end end In my routes.rb map.display ':item', :controller => 'display', :action => 'display' I only seem to have one concern with this, I probably will add a lot of categories later on and think there should be a more DRY-esque way of dealing, rather than hardcoding them. I understand that I need to add into my layout html tags to display relevant information for that particular category. ----Questions---- Is this the right way to approach this type of problem. Will this approach be compatible when I decide to add a gem like *thinking_sphinx* to run search. What issues do you see with my approach and how can I make it better. I was reading something about "Polymorphic Assoc", does that apply in this case, since category exist for all items? Also, I was trying to get a routes to render a URL like "http://localhost/living-room-tv"

  • How can I prevent double file uploading with Amazon S3?

    - by Tony
    I decided to use Amazon S3 for document storage for an app I am creating. One issue I run into is while I need to upload the files to S3, I need to create a document object in my app so my users can perform CRUD actions. One solution is to allow for a double upload. A user uploads a document to the server my Rails app lives on. I validate and create the object, then pass it on to S3. One issue with this is progress indicators become more complicated. Using most out-of-the-box plugins would show the client that file has finished uploading because it is on my server, but then there would be a decent delay when the file was going from my server to S3. This also introduces unnecessary bandwidth (at least it does not seem necessary) The other solution I am thinking about is to upload the file directly to S3 with one AJAX request, and when that is successful, make a second AJAX request to store the object in my database. One issue here is that I would have to validate the file after it is uploaded which means I have to run some clean up code in S3 if the validation fails. Both seem equally messy. Does anyone have something more elegant working that they would not mind sharing? I would imagine this is a common situation with "cloud storage" being quite popular today. Maybe I am looking at this wrong.

  • Howto: Access a second related model in a nested attribute builder block

    - by Joe Cairns
    I have a basic has_many through relationship: class Foo < ActiveRecord::Base has_many :bars, :dependent => :destroy has_many :wtfs :through => :bars accepts_nested_attributes_for :bars, :wtfs end On my crud forms I have a builder block for the wtf, but I need the label to come from the bar (an attribute called label for instance). What's the proper method to do this? Here's the most simple scaffold: <h1>New foo</h1> <% form_for(@foo) do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> <h2>Bars</h2> <% f.fields_for :wtfs do |builder| %> <%= builder.hidden_field :bar_id %> <p> <%= builder.text_field :wtf_data_i_need_to_set %> </p> <% end %> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Back', foos_path %>
