  • Sinatra: How do I provide access to a login form while preventing access to the rest of my Sinatra a

    - by Brandon Toone
    I recently created a Sinatra app with a login form (no basic auth). To prevent access to the app unless the user logged in I put a before block in place before do unless request.path_info == '/login' authenticated? end end I quickly realized that this prevented me from accessing resources in the public directory like my style sheet and logo unless authenticated first as well. To get around that I changed my filter to the following: before do unless request.path_info == '/login' || request.path_info == "/stylesheets/master.css" || request.path_info == "/images/logo.png" authenticated? end end If there were lots of resources I needed to provide exceptions to this way of making them would quickly become overwhelming. What is a better way to code this so I can make exceptions for the public directory or even its specific sub-directories and files like /stylesheets, /images, /images/bg.png but not /secret or /secret/eyes-only.pdf? Or ... Is there a completely different best-practice to handle this situation of locking down everything except the stuff related to logging in (handlers, views, resources)?

  • What is the subject of Rspecs its method

    - by Steve Weet
    When you use the its method in rspec like follows its(:code) { should eql(0)} what is 'its' referring to. I have the following spec that works fine describe AdminlwController do shared_examples_for "valid status" do it { should be_an_instance_of(Api::SoapStatus) } it "should have a code of 0" do subject.code.should eql(0) end it "should have an empty errors array" do subject.errors.should be_an(Array) subject.errors.should be_empty end #its(:code) { should eql(0)} end describe "Countries API Reply" do before :each do co1 = Factory(:country) co2 = Factory(:country) @result = invoke :GetCountryList, "empty_auth" end subject { @result } it { should be_an_instance_of(Api::GetCountryListReply) } describe "Country List" do subject {@result.country_list} it { should be_an_instance_of(Array) } it { should have(2).items } it "should have countries in the list" do subject.each {|c| c.should be_an_instance_of(Api::Country)} end end describe "result status" do subject { @result.status } it_should_behave_like "valid status" end end However if I then uncomment the line with its(:code) then I get the following output AdminlwController Countries API Reply - should be an instance of Api::GetCountryListReply AdminlwController Countries API Reply Country List - should be an instance of Array - should have 2 items - should have countries in the list AdminlwController Countries API Reply result status - should be an instance of Api::SoapStatus - should have a code of 0 - should have an empty errors array AdminlwController Countries API Reply result status code - should be empty (FAILED - 1) 1) NoMethodError in 'AdminlwController Countries API Reply result status code should be empty' undefined method code for <AdminlwController:0x40fc4dc> /Users/steveweet/romad_current/romad/spec/controllers/adminlw_controller_spec.rb:29: Finished in 0.741599 seconds 8 examples, 1 failure It seems as if "its" is referring to the subject of the whole test, namely AdminLwController rather than the current subject. Am I doing something wrong or is this an Rspec oddity?

  • Updating nested attributes causes duplicate entries

    - by params_noob
    I have a has_many and belongs_to relationship between Job and Address. When I try to update Job and Address in the same form, it updates job but creates a duplicate entry for Address. Am I missing something here? The Edit and Update Actions from Jobs: def edit @job = Job.find(params[:id]) end def update @job = Job.find(params[:id]) if @job.update_attributes(job_params) flash[:success] = "Job Updated" redirect_to current_user else render 'edit' end end The edit form: <h1>Edit Job Information</h1> <div class="row"> <div class="span6 offset3"> <%= form_for(@job) do |f| %> <%= render 'shared/error_messages' %> <%= f.label :recipient %> <%= f.text_field :recipient %> <%= f.label :age %> <%= f.text_field :age %> <%= f.label :gender %> <%= f.text_field :gender %> <%= f.label :ethnicity %> <%= f.text_field :ethnicity %> <%= f.label :height %> <%= f.text_field :height %> <%= f.label :weight %> <%= f.text_field :weight %> <%= f.label :hair %> <%= f.text_field :hair %> <%= f.label :eyes %> <%= f.text_field :eyes %> <%= f.label :other_info %> <%= f.text_field :other_info %> <h3> Address Information </h3> <%= f.fields_for :addresses do |address| %> <%= address.label :label, "Label" %> <%= address.text_field :label %> <%= address.label :addy, "Address" %> <%= address.text_field :addy %> <%= address.label :apt, "Apt/Suite/etc" %> <%= address.text_field :apt %> <%= address.label :city, "City" %> <%= address.text_field :city %> <%= address.label :state, "State" %> <%= address.text_field :state %> <%= address.label :zip, "Zip code" %> <%= address.text_field :zip %> <% end %> <%= f.label :instructions, "Service Instructions" %> <%= f.text_field :instructions %> <%= check_box_tag(:rush) %> <%= label_tag(:rush, "Rush?") %> <%= f.submit "Update Job", class: "btn btn-large btn-primary" %> <% end %> </div> </div>

  • 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 to override the attr_protected?

    - by KandadaBoggu
    I have STI implementation as follows: class Automobile < ActiveRecord::Base end class Car < Automobile end class Truck < Automobile end class User < ActiveRecord::Base has_many :automobiles accepts_nested_attributes_for :automobiles end I am creating a list of automobiles for a user. For each automobile, the UI sets the type field and the properties associated with the automobile.While form submission, the type field is ignored as it is a protected attribute. How do I work around this issue? Is there a declarative way to unprotect a protected attribute?

  • What is the best way to read files in an EventMachine-based app?

    - by Theo
    In order not to block the reactor I would like to read files asynchronously, but I've found no obvious way of doing it using EventMachine. I've tried a few different approaches, but none of them feels right: Just read the file, it'll block the reactor, but what the hell, it's not that slow (unless it's a big file, and then it definitely is). Open the file for reading and read a chunk on each tick (but how much to read? too much and it'll block the reactor, too little and reading will get slower than necessary). EM.popen('cat some/file', FileReader) feels really weird, but works better than the alternatives above. In combination with the LineAndTextProtocol it reads lines pretty swiftly. EM.attach, but I haven't found any examples of how to use it, and the only thing I've found on the mailing list is that it's deprecated in favour of… EM.watch, which I've found no examples of how to use for reading files. How do you read files within a EventMachine reactor loop?

  • Active Record Associations: has_one :through? Or multiple has_one's?

    - by jmccartie
    I'm brand new to Rails, so bear with me. I have 3 models: User, Section, and Tick. Each section is created by a user. My guess with this association: class Section < ActiveRecord::Base has_one :user end Next, each user can "tick" off a section -- only once. So for each tick, I have a section_id, user_id, and timestamps. Here's where I'm stuck. Does this call for a "has_one :through" association? If so, which direction? If not, then I'm way off. Which association works here? Thanks!

  • 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?

  • Taking out a subpart from Enumerable

    - by sawa
    I often want to take out a subpart from an Enumerable. The subpart is sometimes at the beginning and sometimes the end of the original Enumerable instance, and the length used to specify the subpart is sometimes that of the subpart and sometimes its complement. That gives four possibilities, but I only know how to do three of them. Is there a way to do the fourth one? Getting the first n elements: [1, 2, 3, 4, 5].first(3) #= [1, 2, 3] or [1, 2, 3, 4, 5].take(3) #= [1, 2, 3] Dropping the first n elements: [1, 2, 3, 4, 5].drop(3) #= [4, 5] Getting the last n elements: [1, 2, 3, 4, 5].last(3) #= [3, 4, 5] Dropping the last n elements: [1, 2, 3, 4, 5].some_method(3) #= [1, 2]

  • Find by include nil object error in rails

    - by SpyrosP
    I've been trying hard to solve this problem but i really don't know what is happening. I have this small piece of code : DiscoveredLocation.find_by_user_id(user.id, :include => [:boss_kills]) The models are : DiscoveredLocation(id, user_id, boss_location_id) BossKill(user_id, monster_id) and associations : Monster belongs_to :boss_location Monster has_many :boss_kills BossKill belongs_to :user BossKill belongs_to :monster DiscoveredLocation belongs_to :user DiscoveredLocation belongs_to :boss_location DiscoveredLocation has_many :monsters, :through => :boss_location DiscoveredLocation has_many :boss_kills, :through => :monsters When i executed the find_by i get this error : NoMethodError in BossesController#index You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.each If i change the include option to any other model, like :monster, it works great. I'm pretty much owned by this problem :P. Maybe somebody can help me ? :)

  • Can I retrieve objects from a complex query that limits results to fields from a single table?

    - by Sean Redmond
    I have a model whose rows I always want to sort based on the values in another associated model and I was thinking that the way to implement this would be to use set_dataset in the model. This is causing query results to be returned as hashes rather than objects, though, so none of the methods from the class can be used when iterating over the dataset. I basically have two classes class SortFields < Sequel::Model(:sort_fields) set_primary_key :objectid end class Items < Sequel::Model(:items) set_primary_key :objectid one_to_one :sort_fields, :class => SortFields, :key => :objectid end Some backstory: the data is imported from a legacy system into mysql. The values in sort_fields are calculated from multiple other associated tables (some one-to-many, some many-to-many) according to some complicated rules. The likely solution will be to just add the values in sort_fields to items (I want to keep the imported data separate from the calculated data, but I don't have to). First, though, I just want to understand how far you can go with a dataset and still get objects rather than hashes. If I set the dataset to sort on a field in items like so class Items < Sequel::Model(:items) set_primary_key :objectid one_to_one :sort_fields, :class => SortFields, :key => :objectid set_dataset(order(:sortnumber)) end then the expected clause is added to the generated SQL, e.g.: >> Items.limit(1).sql => "SELECT * FROM `items` ORDER BY `sortnumber` LIMIT 1" and queries still return objects: >> Items.limit(1).first.class => Items If I order it by the associated fields though... class Items < Sequel::Model(:items) set_primary_key :objectid one_to_one :sort_fields, :class => SortFields, :key => :objectid set_dataset( eager_graph(:sort_fields). order(:sort1, :sort2, :sort3) ) end ...I get hashes ?> Items.limit(1).first.class => Hash My first thought was that this happens because all fields from sort_fields are included in the results and maybe if selected only the fields from items I would get Items objects again: class Items < Sequel::Model(:items) set_primary_key :objectid one_to_one :sort_fields, :class => SortFields, :key => :objectid set_dataset( eager_graph(:sort_fields). select(:items.*). order(:sort1, :sort2, :sort3) ) end The generated SQL is what I would expect: >> Items.limit(1).sql => "SELECT `items`.* FROM `items` LEFT OUTER JOIN `sort_fields` ON (`sort_fields`.`objectid` = `items`.`objectid`) ORDER BY `sort1`, `sort2`, `sort3` LIMIT 1" It returns the same rows as the set_dataset(order(:sortnumber)) version but it still doesn't work: >> Items.limit(1).first.class => Hash Before I add the sort fields to the items table so that they can all live happily in the same model, is there a way to tell Sequel to return on object when it wants to return a hash?

  • Store request.headers in a serialized model attribute

    - by Horace Loeb
    Here's my model: class Comment < ActiveRecord::Base serialize :request_headers end But when I try to do @comment.request_headers = request.headers I get a TypeError (can't dump anonymous class Class) exception. Another way to ask my question: how can I convert request.headers into a Hash? It uses a Hash under the covers so this should be easy, no?

  • Regarding Authlogic and page redirection.

    - by Paddy
    I am using authlogic for authentication in my Rails app. Have named routes for the frequent actions, viz: map.login "login", :controller = "user_sessions", :action = "new" map.logout "logout", :controller = "user_sessions", :action = "destroy" map.register "register", :controller = "users", :action = "new" map.edit 'user/edit/:id', :controller = "users", :action = "edit" But also in my routes.rb i have these automatically created REST routes too: map.resources :user_sessions map.resources :users The problem now is that a user can login from two different routes. Ex: From, http://localhost/login and also from http ://localhost/user_sessions/new. How do i restrict access only from the named route i have defined and not allow from user_sessions/new?

  • Rails Functional Test Failing Due to Association

    - by Koby
    I have an accounts model that holds some basic account info (account name, website, etc). I then have a user model that has the following in the app/models/user.rb belongs_to :account I also have the following in my routes.rb map.resources :account, :has_many => [:users, :othermodel] the problem I'm facing is that the following test is failing: test "should create user" do assert_difference('User.count') do post :create, :user => { } #this is the line it's actually failing on end assert_redirected_to user_path(assigns(:user)) #it doesn't get here yet end The error it gives is "Can't find Account without ID" so I kind of understand WHY it's failing, because of the fact that it doesn't have the account object (or account_id as it were) to know under what account to create the user. I have tried variations of the following but I am completely lost: post :create, :user => { accounts(:one) } #I have the 'fixtures :accounts' syntax at the top of the test class post :create, [accounts(:one), :user] => { } post :create, :user => { accounts(:one), #other params for :user } and like I said, just about every variation I could think of. I can't find much documentation on doing this and this might be why people have moved to Factories for doing test data, but I want to understand things that come standard in Rails before moving onto other things. Can anyone help me get this working?

  • How do I get AuthLogic to skip Password validation?

    - by ndp
    I think I'm just missing something obvious. I send a user a perishable token embedded in a link. They click on it, and they come back to the site. I want to log them in automatically (I'm not building a banking app). This seems like this should be simple, but all the examples I've found require a password. How do I skip this completely? I just seem to get UserSession.create to work.
