  • Restricting Access in ERB code.

    - by LGFaler
    I am trying to build a CMS using ERB. Is there a way you can give ERB code read-only access to your models? For instance, I want to be able to load any information on my models (Model.all, Model.find_by_slug, Model.find_by_name, Model.other_model.name, etc...), but I don't want to be able to change this data. Can you disable ERB from executing commands that would make database changes (Model.save, Model.update, Model.delete, Model.destroy, etc.)???

  • CSRF protecting and cross site form access

    - by fl00r
    Hi. I aw working on cross site authentication (some domains have got common authentication). So I want to send authentication data (login, password) to main domain from others. How should I use protect_from_forgery and how can I check if data received from valid domain? What I am thinking now is to turn off protect_from_forgery for session controller and check domain name of received data. But maybe I can configure CSRF protection for not only one domain?

  • Splitting PDF to png

    - by Josh Crowder
    I'm using paperclip to upload a pdf. Once the file is uploaded I need to split every page into a png. This is the command I think I need to use convert -size 640x300 fileName.pdf slide.png Now if I run that command from terminal it works fine, but I need a way of getting each slides name so I can add it into a model. What's the best way to achieve this?

  • How do I find the .max of an attribute value among a group of different Models?

    - by Angela
    Hi, everyone: I am also open to just straight-up refactoring what I'm finding to be pretty repetitive, but to give a baseline of how it's working.... I have for every contact a Campaign, which has_many of three types of Models: Email, Call, and Letter. When an Email (Call or Letter) has been executed for a specific contact, I have a Contact_Email(_or_Call_or_Letter) which belongs to both the Contact and the Model (Email_or_Call_or_Letter). Each Contact_Email for example pairing has a :date_sent attribute. So does each Contact_Call and Contact_Letter. How do I find the latest of all of them? Here is the code I wrote that can find the latest Email and my finding retyping similar code for Call and Letter, but then stuck on how to do a .max on all of them: def last_email(contact) #get campaign the contact belongs to @campaign = Campaign.find_by_id(contact.campaign_id) @last_email = ContactEmail.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") @last_call = ContactCall.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") @last_letter = ContactLetter.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") # how do I get the latest of all of these to display? if @last_sent_email.nil? return "no email sent" else return @last_sent_email.date_sent end end Question 1: With what I have, how can I find effectively @last_event given I can find the last Email, last Call, and last Letter for every contact? Question 2: How can I remove the repetitive code that I have to write for each Model?

  • ActiveRecord field normalization

    - by Bill
    I feel bad asking this question, as I thought I knew enough about Activerecord to answer this myslef. But such is the way of having SO available ... I'm trying to remove the commas from a field in a model of mine, I want the user to be able to type a number , ie 10,000 and that number be stored in the database as 10000. I was hoping that I could do some model-side normalization to remove the comma. I don't want to depend on the view or controller to properly format my data. I tried ; before_validation :normalize def normalize self['thenumber'] = self['thenumber'].to_s.gsub(',','') end no worky :(

    - by Tam

  • Checking ActiveRecord Associations in RSpec.

    - by alokswain
    I am learning how to write test cases using Rspec. I have a simple Post Comments Scaffold where a Post can have many Comments. I am testing this using Rspec. How should i go about checking for Post :has_many :comments. Should I stub Post.comments method and then check this with by returning a mock object of array of comment objects? Is testing for AR associations really required ?

  • How to run only the latest/a given test using Rspec?

    - by marcgg
    Let's say I have a big spec file with 20 tests because I'm testing a large model and I had no other way of doing it : describe Blah it "should do X" do ... end it "should do Y" do ... end ... it "should do Z" do ... end end Running a single file is faster than running the whole test suite, but it's still pretty long. Is there a way to run the last one (ie the one at the end of the file, here "should do Z")? If this is not possible, is there a way to specify which test I want to run in my file ?

  • Overriding rubies spaceship operator <=>

    - by ericsteen1
    I am trying to override rubies <= (spaceship) operator to sort apples and oranges so that apples come first sorted by weight, and oranges second, sorted by sweetness. Like so: module Fruity attr_accessor :weight, :sweetness def <=>(other) # use Array#<=> to compare the attributes [self.weight, self.sweetness] <=> [other.weight, other.sweetness] end include Comparable end class Apple include Fruity def initialize(w) self.weight = w end end class Orange include Fruity def initialize(s) self.sweetness = s end end fruits = [Apple.new(2),Orange.new(4),Apple.new(6),Orange.new(9),Apple.new(1),Orange.new(22)] p fruits #should work? p fruits.sort But this does not work, can someone tell what I am doing wrong here, or a better way to do this?

  • Choosing gems to work with AWS

    - by Sergii Vozniuk
    Suppose a service written with RoR starts to use AWS S3 to store some data. What is the best library to use for working with AWS S3? Currently the main two alternatives for me are: RightScale AWS Ruby gems http://github.com/rightscale/right_aws AWS::s3 http://amazon.rubyforge.org/ What are their main advantages and disadvantages? What if later service will need to use other AWS (like EC2)? What other gems do you use and why? Thanks!

    I'm trying to print a simple array defined in my controller into my view with a new line for each element. But what it's doing is printing the whole array on one line. Here's my controller: class TodosController < ApplicationController def index @todo_array = [ "Buy Milk", "Buy Soap", "Pay bill", "Draw Money" ] end end Here's my view: <%= @todo_array.each do |t| %> <%= puts t %><\br> <% end %> Here's the result: <\br> <\br> <\br> <\br> ["Buy Milk", "Buy Soap", "Pay bill", "Draw Money"]

  • Nokogiri Truncating XML Input

    - by bdorry
    I am having issues with a colleagues machine truncating XML while using Nokogiri to parse a Media RSS feed. The feed is a standard Media RSS feed, and the XML is not malformed. It looks like it simply stops at a certain point in the XML and closes any tags that would have been open at that current point in the document. (Unfortunately I do not have the XML avialable to me right now, but I will update this question with the actual XML when I have it available to me). My confusion comes from it working fine on my machine (OSX 10.6, Nokogiri 1.4.4) while it in correctly on his machine using the same setup - however his machine is a few years older. I imagine that there is a difference somewhere but unfortunately I don't know what to look for. Any thoughts or direction would be greatly appreciated.

  • Updating protected attributes using update_all

    - by Jack
    Since you cannot use the normal 'update' and 'update_attribute' methods from ActiveRecord to update a protected attribute, is the following the best way to update an attribute for a single user? User.update_all("admin = true","id = 1") I'm guessing this doesn't lie in the 'best practice' category, so I'm just curious if there is a more appropriate way.
