  • double slash apache configuration

    - by VP
    Hi, i'm deploying a ror application and now i have to rewrite the url (in apache) to add a prefix www to the url add / to the end of the url So i took the following approach: RewriteCond %{REQUEST_URI} ^/[^\.]+[^/]$ RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1/ [R=301,L] RewriteCond %{HTTP_HOST} ^foo\.com RewriteRule ^(.*)$ http://www.foo.com/$1 [R=301,L] The problem is that it is appending two trailing slash to my url So for example a resource /question/ask are becoming: http://foo.com//question/ask I tried to add the following Rule before all my Rewrite rules to try to remove the double //: RewriteCond %{REQUEST_URI} ^// RewriteRule ([^/]*)/+(.*) http://www.foo.com/$1/$2 [R=301,L] but it didnt work.. any idea to rip off all extras "//" added to the url?

  • 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 to get custom form fields from controller -- a.k.a. how to not use date helpers in form

    - by 99miles
    I created a form with scaffold that includes two datetime fields. I replaced them with a datepicker, and now I'm trying to grab the date from within the controller. Instead of having ruby do all the magic work with the datefields, I instead just have to fields, start_date and stop_date that I want to use, but I can't figure out how to grab them from within my controller. Hints? Thanks!

  • Adding a computed column to an ActiveRecord query

    - by bmwbzz
    Hi, I am running a query using a scope and some conditions. Something like this: conditions[:offset] = (options[:page].to_i - 1) * PAGE_SIZE unless options[:page].blank? conditions[:limit] = options[:limit] ||= PAGE_SIZE scope = Promo.enabled.active results = scope.all conditions I'd like to add a computed column to the query (at the point when I'm now calling scope.all). Something like this: (ACOS(least(1,COS(0.71106459055501)*COS(-1.2915436464758)*COS(RADIANS(addresses.lat))*COS(RADIANS(addresses.lng))+ COS(0.71106459055501)*SIN(-1.2915436464758)*COS(RADIANS(addresses.lat))*SIN(RADIANS(addresses.lng))+ SIN(0.71106459055501)*SIN(RADIANS(addresses.lat))))*3963.19) as accurate_distance Is there a way to do that without just using find_by_sql and rewriting the whole existing query? Thanks!

  • Simple CanCan problem

    - by sscirrus
    I have just started with CanCan and here's a sample of the code: # Ability.rb def initialize(user) user ||= User.new can :read, Link end # view.html.erb <% if can? :read, @link %> ... <% end %> This is from the github repo for CanCan but this doesn't seem to work (it returns false and stops the ... code from running). When I change the view to <% if can? :read, Link %>, it works. But, this is different to the CanCan readme. Do you know where I'm going wrong here?

  • CSRF protection 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?

  • problem with parsing string from excel file

    - by ohana
    hi, i have ruby code to parse data in excel file using Parseexcel gem. I need to save 2 columns in that file into a Hash, here is my code: worksheet.each { |row| if row != nil key = row.at(1).to_s.strip value = row.at(0).to_s.strip if !parts.has_key?(key) and key.length 0 parts[key] = value end end } however it still save duplicate keys into the hash: "020098-10". I checked the excel file at the specified row and found the difference are " 020098-10" and "020098-10". the first one has a leading space while the second doesn't. I dont' understand is it true that .strip function already remove all leading and trailing white space? also when i tried to print out key.length, it gave me these weird number: 020098-10 length 18 020098-10 length 17 which should be 9....

  • rake gems:refresh_specs error on unpacked gems

    - by Urf
    Following the great advice of Chris Wanstrath, I decided to vendor everything. However, whenever I run a rake task now I get an error for each of my unpacked gems stating config.gem: Unpacked gem gemname in vendor/gems has no specification file. Run 'rake gems:refresh_specs' to fix this. I've done this but no dice. Anyone have the same issue? If so, how do I resolve? TIA

  • Test if current page is inside a shadowbox? (so i can close the shadowbox and reopen that page in t

    - by Max Williams
    Hi all I have a couple of pages in my site which open in a shadowbox window rather than the main window. My problem is that if the user session expires, then the user clicks on one of the links that open in a shadowbox, they are redirected to the login page INSIDE THE SHADOWBOX, which i don't want. I've been trying to think of the best way to handle this - one way i thought of, which seems a bit clumsy tbh, was on the login page to test if we're in a shadowbox, and if we are then close it and redirect the parent window to the login page. a) does this seem like a sensible plan? I added the following to my login page, which works: $(document).ready(function(){ if(window.parent.location != window.location){ window.parent.location.href = window.location; } } but i have to wait for the shadowbox to finish loading the page and then redirect. So it's working but like i say a bit clumsy. Is there a nicer way? grateful for any advice - max

  • Multitenant shared user account?

    - by jpartogi
    Dear all, Based on your experience, which is the route to go for a multi-tenant user login? One user login per account. Which means if there is one user that has access to multiple account, there will be redundancy of record in the database One user login for all account that she has privileges to. Which means one user record has access to multiple account if she has privileges to that account. From your experience, which one is better and why? I was thinking to choose the latter, but I don't know whether it will cause security issue or less flexibility. Thank you for sharing your experience.

  • Mongoid Embeds_many won't save on nested form

    - by Brandon J McKay
    I've got an embeds_many association I'm trying to set up which I've done successfully before, but I'm trying to do it all in one nested form and I can't figure it out. Let's say we have a pocket model: class Pocket include Mongoid::Document field :title, type: String embeds_many :coins, cascade_callbacks: true end and a Coin Model: class Coin include Mongoid::Document field :name, type: String embedded_in :pocket end in my form for the pocket, I'm using: = f.fields_for @pocket.coins do |coin| = coin.text_field :name My controller is the default scaffolded controller. When I use the console, it saves fine and I can see the new pocket and coin I've created. But when I try to create or update a coin from the form, the pocket saves but the coin remains unchanged. What am I missing here?

  • map.resource, parameter restrictions

    - by Tiago
    I've a controller :platform here. I'm trying to do something like: /:platform_name/ to redirect to its show, with the parameter. Here is what I've got: map.resource :platform, :as => ':platform_name', :platform_name => /pc|ps2|ps3|wii|ds|psp|xbox-360/ It's working fine. I've other neasted resources to it, and all them are accessing. But. The problem is, I've only those platform names, but when it doesnt fine another route, it aways fall on this. if I try /whatever/, it will look for the *platform_name = whatever*. I was expecting it to fall into the map.connect ':controller/:action/:id' rule. When I did *:platform_name = /pc|ps2|ps3|wii|ds|psp|xbox-360/*, wasnt expected that this rule only apply when the regular expression is fit? how could i restrict this?

  • How Do I Search Between a Date Rang Using the ActiveRecord Model?

    - by Russ Bradberry
    I am new to both Ruby and ActiveRecord. I currently have a need to modify and existing piece of code to add a date range in the select. The current piece goes like this: ReportsThirdparty.find(:all, :conditions => {:site_id=>site_id, :campaign_id=>campaign_id, :size_id=>size_id}) Now, I need to add a range, but I am not sure how to do the BETWEEN or >= or <= operators. I guess what I need is something similar to: ReportsThirdparty.find(:all, :conditions => {:site_id=>site_id, :campaign_id=>campaign_id, :size_id=>size_id, :row_date=>"BETWEEN #{start_date} AND #{end_date}") Even if this did work, I know that using interpolation here would leave me subject to SQL injection attacks.

  • Help with Ruby Date Compare

    - by Kevin
    Yes, I've read and done teh Google many times but I still can't get this working... maybe I'm an idiot :) I have a system using tickets. Start date is "created_at" in the timestamps. Each ticket closes 7 days after "created_at". In the model, I'm using: def closes (self.created_at + 7.days) end I'm trying to create another method that will take "closes" and return it as how many days, hours, minutes, and seconds are left before the ticket closes. Anyone want to help and/or admonish my skills? ;)
