  • Super inplace controls in_place_select displays incorrectly

    - by Magicked
    I'm using the super_inplace_controls plugin to allow users to edit fields on the "show" page. However, I'm running into an issue with the in_place_select function. Here is my view: <p> <b>Status:</b> <%= in_place_select :incident, :incident_status, :choices => @statuses.map { |e| [e.name, e.id] } %> </p> This is in the 'Incident' view. IncidentStatus is a separate table that has_many Incidents. In the Incident controller, I retrieve @statuses like so: @statuses = IncidentStatus.find(:all) Everything works fine for the in_place_select, except the original display. In my browser, it shows: Status: #<IncidentStatus:0x1033147d8> Which means it's not grabbing the current incident_status.name, but it's just changing the object to a string. I'm not sure how to fix this! When I click on the "IncidentStatus:0x1033147d8", everything works properly and I can select the proper fields. Thanks for any help!

  • Paperclip: "missing" image when uses has_one

    - by EricR
    I'm working on a website that allows people who run bed and breakfast businesses to post their accommodations. I would like to require that they include a "profile image" of the accommodation when they post it, but I also want to give them the option to add more images later (this will be developed after). I thought the best thing to do would be to use the Paperclip gem and have a Accommodation and a Photo in my application, the later belonging to the first as an association. A new Photo record is created when they create an Accommodation. It has both id and accommodation_id attributes. However, the image is never uploaded and none of the Paperclip attributes get set (image_file_name: nil, image_content_type: nil, image_file_size: nil), so I get Paperclip's "missing" photo. Any ideas on this one? It's been keeping me stuck for a few days now. Accommodation models/accommodation.rb class Accommodation < ActiveRecord::Base validates_presence_of :title, :description, :photo, :thing, :location attr_accessible :title, :description, :thing, :borough, :location, :spaces, :price has_one :photo end controllers/accommodation_controller.erb class AccommodationsController < ApplicationController before_filter :login_required, :only => {:new, :edit} uses_tiny_mce ( :options => { :theme => 'advanced', :theme_advanced_toolbar_location => 'top', :theme_advanced_toolbar_align => 'left', :theme_advanced_buttons1 => 'bold,italic,underline,bullist,numlist,separator,undo,redo', :theme_advanced_buttons2 => '', :theme_advanced_buttons3 => '' }) def index @accommodations = Accommodation.all end def show @accommodation = Accommodation.find(params[:id]) end def new @accommodation = Accommodation.new end def create @accommodation = Accommodation.new(params[:accommodation]) @accommodation.photo = Photo.new(params[:photo]) @accommodation.user_id = current_user.id if @accommodation.save flash[:notice] = "Successfully created your accommodation." render :action => 'show' else render :action => 'new' end end def edit @accommodation = Accommodation.find(params[:id]) end def update @accommodation = Accommodation.find(params[:id]) if @accommodation.update_attributes(params[:accommodation]) flash[:notice] = "Successfully updated accommodation." render :action => 'show' else render :action => 'edit' end end def destroy @accommodation = Accommodation.find(params[:id]) @accommodation.destroy flash[:notice] = "Successfully destroyed accommodation." redirect_to :inkeep end private def check_owner end end views/accommodations/_form.html.erb <%= form_for @accommodation, :html => {:multipart => true} do |f| %> <%= f.error_messages %> <p> Title<br /> <%= f.text_field :title, :size => 60 %> </p> <p> Description<br /> <%= f.text_area :description, :rows => 17, :cols => 75, :class => "mceEditor" %> </p> <p> Photo<br /> <%= f.file_field :photo %> </p> [... snip ...] <p><%= f.submit %></p> <% end %> Photo The controller and views are still the same as when Rails generated them. models/photo.erb class Photo < ActiveRecord::Base attr_accessible :image_file_name, :image_content_type, :image_file_size belongs_to :accommodation has_attached_file :image, :styles => { :thumb=> "100x100#", :small => "150x150>" } end

Thanks for your help.

  • Nested Resource testing RSpec

    - by Joseph DelCioppio
    I have two models: class Solution < ActiveRecord::Base belongs_to :owner, :class_name => "User", :foreign_key => :user_id end class User < ActiveRecord::Base has_many :solutions end with the following routing: map.resources :users, :has_many => :solutions and here is the SolutionsController: class SolutionsController < ApplicationController before_filter :load_user def index @solutions = @user.solutions end private def load_user @user = User.find(params[:user_id]) unless params[:user_id].nil? end end Can anybody help me with writing a test for the index action? So far I have tried the following but it doesn't work: describe SolutionsController do before(:each) do @user = Factory.create(:user) @solutions = 7.times{Factory.build(:solution, :owner => @user)} @user.stub!(:solutions).and_return(@solutions) end it "should find all of the solutions owned by a user" do @user.should_receive(:solutions) get :index, :user_id => @user.id end end And I get the following error: Spec::Mocks::MockExpectationError in 'SolutionsController GET index, when the user owns the software he is viewing should find all of the solutions owned by a user' #<User:0x000000041c53e0> expected :solutions with (any args) once, but received it 0 times Thanks in advance for all the help.

  • How to select table column names in a view and pass to controller in rails?

    - by zachd1_618
    So I am new to Rails, and OO programming in general. I have some grasp of the MVC architecture. My goal is to make a (nearly) completely dynamic plug-and-play plotting web server. I am fairly confused with params, forms, and select helpers. What I want to do is use Rails drop downs to basically pass parameters as strings to my controller, which will use the params to select certain column data from my database and plot it dynamically. I have the latter part of the task working, but I can't seem to pass values from my view to controller. For simplicity's sake, say my database schema looks like this: --------------Plot--------------- |____x____|____y1____|____y2____| | 1 | 1 | 1 | | 2 | 2 | 4 | | 3 | 3 | 9 | | 4 | 4 | 16 | | 5 | 5 | 25 | ... and in my Model, I have dynamic selector scopes that will let me select just certain columns of data: in Plot.rb class Plot < ActiveRecord::Base scope :select_var, lambda {|varname| select(varname)} scope :between_x, lambda {|x1,x2| where("x BETWEEN ? and ?","#{x1}","#{x2}")} So this way, I can call: irb>>@p1 = Plot.select_var(['x','y1']).between_x(1,3) and get in return a class where @p1.x and @p1.y1 are my only attributes, only for values between x=1 to x=4, which I dynamically plot. I want to start off in a view (plot/index), where I can dynamically select which variable names (table column names), and which rows from the database to fetch and plot. The problem is, most select helpers don't seem to work with columns in the database, only rows. So to select columns, I first get an array of column names that exist in my database with a function I wrote. Plots Controller def index d=Plot.first @tags = d.list_vars end So @tags = ['x','y1','y2'] Then in my plot/index.html.erb I try to use a drop down to select wich variables I send back to the controller. index.html.erb <%= select_tag( :variable, options_for_select(@plots.first.list_vars,:name,:multiple=>:true) )%> <%= button_to 'Plot now!', :controller =>"plots/plot_vars", :variable => params[:variable]%> Finally, in the controller again Plots controller ... def plot_vars @plot_data=Plot.select_vars([params[:variable]]) end The problem is everytime I try this (or one of a hundred variations thereof), the params[:variable] is nill. How can I use a drop down to pass a parameter with string variable names to the controller? Sorry its so long, I have been struggling with this for about a month now. :-( I think my biggest problem is that this setup doesn't really match the Rails architecture. I don't have "users" and "articles" as individual entities. I really have a data structure, not a data object. Trying to work with the structure in terms of data object speak is not necessarily the easiest thing to do I think. For background: My actual database has about 250 columns and a couple million rows, and they get changed and modified from time to time. I know I can make the database smarter, but its not worth it on my end. I work at a scientific institute where there are a ton of projects with databases just like this. Each one has a web developer that spends months setting up a web interface and their own janky plotting setups. I want to make this completely dynamic, as a plug-and-play solution so all you have to do is specify your database connection, and this rails setup will automatically show and plot which data you want in it. I am more of a sequential programmer and number cruncher, as are many people here. I think this project could be very helpful in the end, but its difficult to figure out for me right now.

  • 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.

  • Rails: Obfuscating Image URLs on Amazon S3? (security concern)

    - by neezer
    To make a long explanation short, suffice it to say that my Rails app allows users to upload images to the app that they will want to keep in the app (meaning, no hotlinking). So I'm trying to come up with a way to obfuscate the image URLs so that the address of the image depends on whether or not that user is logged in to the site, so if anyone tried hotlinking to the image, they would get a 401 access denied error. I was thinking that if I could route the request through a controller, I could re-use a lot of the authorization I've already built into my app, but I'm stuck there. What I'd like is for my images to be accessible through a URL to one of my controllers, like: http://railsapp.com/images/obfuscated?member_id=1234&pic_id=7890 If the user where to right-click on the image displayed on the website and select "Copy Address", then past it in, it would be the SAME url (as in, wouldn't betray where the image is actually hosted). The actual image would be living on a URL like this: http://s3.amazonaws.com/s3username/assets/member_id/pic_id.extension Is this possible to accomplish? Perhaps using Rails' render method? Or something else? I know it's possible for PHP to return the correct headers to make the browser think it's an image, but I don't know how to do this in Rails... UPDATE: I want all users of the app to be able to view the images if and ONLY if they are currently logged on to the site. If the user does not have a currently active session on the site, accessing the images directly should yield a generic image, or an error message.

  • Rails precision error

    - by dontangg
    When I run this in my Rails application: my_envelope.transactions.sum(:amount) This SQL is shown in the log files: SQL (0.3ms) SELECT SUM("transactions"."amount") AS sum_id FROM "transactions" WHERE (envelope_id = 834498537) And this value is returned: <BigDecimal:1011be570,'0.2515999999 9999997E2',27(27)> As you can see, the value is 25.159999. It should be 25.16. When I run the same SQL on the database myself, the correct value is returned. I'm a little confused because I know that there are precision problems with Floats, but it is returning a BigDecimal. The SQL column type is decimal. Any ideas?

  • How do I update a cumulative field in a Rails database (using ActiveRecord or Mongoid)?

    - by picardo
    I want to update a field in a database table that has to have a cumulative value. So basically I need to find the current value of the field and update it using a new number. My first inefficient try at this (in Mongoid) is: v = Landlord.where(:name=>"Lorem") v.update_attributes(:violations=>v.violations + 10) Is there a simple method than making one query to read, then sum up, and another query to write?

  • Problem with user login validation by 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?

  • Rails, different routes for production app.

    - by Joseph Silvashy
    Well, maybe not just different routes. Here is the issue at hand, we have an app that we want to present the users with a "beta sign-up" form when the app is running in production, but we still want to be able to login, however in development the app should function normally. For example in development the app's root path would be the page that show's all the products (using a store as an example) but in production we want the app to present the user with a beta page that just has a form for leaving an email, but also be able to sign-in for users that have accounts. We don't need any help with authentication, that's all sorted out more just the setup of redirecting users to the beta page in production so they can't explore the site unless they are logged in. We are using Devise so I thought maybe we could put something in our application controller that's like: before_filter :authenticate_user! if ENV['RAILS_ENV'] == 'production' But that doesn't seem like it works.

  • In Rails, a Sweeper isn't getting called in a Model-only setup

    - by charliepark
    I'm working on a Rails app, where I'm using page caching to store static html output. The caching works fine. I'm having trouble expiring the caches, though. I believe my problem is, in part, because I'm not expiring the cache from my controller. All of the actions necessary for this are being handled within the model. This seems like it should be doable, but all of the references to Model-based cache expiration that I'm finding seem to be out of date, or are otherwise not working. In my environment.rb file, I'm calling config.load_paths += %W( #{RAILS_ROOT}/app/sweepers ) And I have, in the /sweepers folder, a LinkSweeper file: class LinkSweeper < ActionController::Caching::Sweeper observe Link def after_update(link) clear_links_cache(link) end def clear_links_cache(link) # expire_page :controller => 'links', :action => 'show', :md5 => link.md5 expire_page '/l/'+ link.md5 + '.html' end end So ... why isn't it deleting the cached page when I update the model? (Process: using script/console, I'm selecting items from the database and saving them, but their corresponding pages aren't deleting from the cache), and I'm also calling the specific method in the Link model that would normally invoke the sweeper. Neither works. If it matters, the cached file is an md5 hash off a key value in the Links table. The cached page is getting stored as something like /l/45ed4aade64d427...99919cba2bd90f.html. Essentially, it seems as though the Sweeper isn't actually observing the Link. I also read (here) that it might be possible to simply add the sweeper to config.active_record.observers in environment.rb, but that didn't seem to do it (and I wasn't sure if the load_path of app/sweepers in environment.rb obviated that).

  • using respond_to format.js to replace the content of a textarea on rails

    - by Stacia
    I have some saved text in my create controller. If it's not stressful, I'd like it to populate a textarea on the page with the saved text along with displaying the error message fields (which is what's already happening). I've used things like replace_html before, but I don't know if there's an easy way to get to textarea or text field IDs and just replace the value of the text. For now I'm just going to do some javascript but it would be nice to know the rails shortcut. edit: I wasn't in the right mindset because this app uses extjs and was trying to figure out how to do it this way. The text box is actually an ext status bar (same as here : http://www.extjs.com/deploy/dev/examples/statusbar/statusbar-demo.html ) which doesn't get created until the page is finished loading. When I try to enter commnands like the first poster suggested, I get "setvalue is not a function". Playing with firebug on the page I can get it to set the value after loading by using (whatever method to get it through ext or scriptaculous).value = "lol" but none of the page update things work with this.
