  • Is it possible to do have Capistrano do a checkout over a reverse SSH tunnel?

    - by James A. Rosen
    I am developing an application that resides on a public host but whose source I must keep in a Git repository behind a corporate firewall. I'm getting very tired of the slowness of deploying via scp (copying the whole repository and shipping it over SSH on each deploy) and would like to have the remote host simply do a git pull to update. The problem is that the firewall prohibits incoming SSH connections. Would it be possible for me to set up an SSH tunnel from my computer to the deployment computer and use my repository as the source for the git pull? After all, git is distributed, so my copy is just as valid a repository as the central one. If this is possible, what would the tunnel command and the Capistrano configuration be? I think the tunnel will look something like ssh -R something:deployserver.com:something [email protected]

  • Retrieving all objects in code upfront for performance reasons

    - by ming yeow
    How do you folks retrieve all objects in code upfront? I figure you can increase performance if you bundle all the model calls together? This makes for a bigger deal, especially if your DB cannot keep everything in memory def hitDBSeperately { get X users ...code get Y users... code get Z users... code } Versus: def hitDBInSingleCall { get X+Y+Z users code for X code for Y... }

  • Rails: unexpected behavior updating a shared instance

    - by Pascal Lindelauf
    I have a User object, that is related to a Post object via two different association paths: Post --(has_many)-- comments --(belongs to)-- writer (of type User) Post --(belongs to)-- writer (of type User) Say the following hold: user1.name == "Bill" post1.comments[1].writer == user1 post1.writer == user1 Now when I retrieve the post1 and its comments from the database and I update post1.comments[1].writer like so: post1.comments[1].writer.name = "John" I would expect post1.writer to equal "John" too. But it doesn't! It still equals "Bill". So there seems to be some caching going on, but the kind I would not expect. I would expect Rails to be clever enough to load exactly one instance of the user with name "Bill"; instead is appears to load two individual ones: one for each association path. Can someone explain how this works exactly and how I am to handle these types of situations the "Rails way"?

  • Rails - Permission denied when try to save uploaded file in windows

    - by logoin
    I'm writing my own file upload in rails. I saw some related questions but it doesn't answer my question. I use File.open ("#{RAILS_ROOT}/public/docs/attachments/#{@file_name}", "wb") {|f| f.write(@temp_file.read)} to write the file on my local machine (OS: Windows XP) instead of saving it in database. I got a Permission denied error on the File.open method. Since I have cygwin installed, I chmod 777 the folder that files should write to and also make sure the file I upload can be read. But I'm still getting the same error. Any ideas? Thanks!

  • Rails: Easiest way to provide file downloads?

    - by Schroedinger
    G'day guys, currently have almost finished writing a rails application that allows a CSV download of the database. This is generated when the index is first viewed. Is there an easy way to insert a link to a helper that returns a CSV document? That is to say is it easy to insert links to helpers? This would make a lot of problems I've been having much easier

  • has_one update problem

    - by Kalyan M
    I have two models, User and Account. Each user may have one account. Creating an account for a user works fine. My problem is that when I try to update the account, the previous accounts user_id is nullified and a new account row is created with the user_id. I do not want this happening. I want to update the existing row with the changes to account. How do I do this? Thanks.

  • CanCan polymorphic resource access problem

    - by Call 'naive' True
    Hi everybody, i don't quite understand how to restrict access to links in this particular case with CanCan. I always get "Edit" link displayed. So i believe the problem is in my incorrect definition of cancan methods(load_ and authorize_). I have CommentsController like that: class CommentsController < ApplicationController before_filter :authenticate_user! load_resource :instance_name => :commentable authorize_resource :article def index @commentable = find_commentable #loading our generic object end ...... private def find_commentable params.each { |name, value| if name =~ /(.+)_id$/ return $1.classify.constantize.includes(:comments => :karma).find(value) end } end end and i have in comments/index.html.erb following code that render file from other controller: <%= render :file => "#{get_commentable_partial_name(@commentable)}/show.html.erb", :collection => @commentable %> you can think about "#{get_commentable_partial_name(@commentable)}" like just "articles" in this case. Content of "articles/show.html.erb": <% if can? :update, @commentable %> <%= link_to 'Edit', edit_article_path(@commentable) %> | <% end %> my ability.rb: class Ability include CanCan::Ability def initialize(user) user ||= User.new # guest user if user.role? :admin can :manage, :all elsif user.role? :author can :read, [Article, Comment, Profile] can :update, Article, :user_id => user.id end end end relations with models is: class Comment < ActiveRecord::Base belongs_to :commentable, :polymorphic => true, :dependent => :destroy ... end class Article < ActiveRecord::Base has_many :comments, :as => :commentable, :dependent => :destroy ... end i have tried debug this issue like that user = User.first article = Article.first ability = Ability.new(user) ability.can?(:update, article) and i always get "= true" in ability check Note: user.role == author and article.user_id != user.id if you need more information please write thank's for your time && sorry for my english

  • Rails: Settingslogic accessible to users?

    - by neezer
    I have my app configured with Settingslogic, which I love. My question is how to I make a page on my Rails app where Administrators can make changes to the settings specified in config/settings.yml?? I assume said page would have to read and display appropriate form fields for all the values in the YAML file, then save those values back to config/settings.yml? Would those settings take effect immediately or would the server need to be restarted? Bit lost here. Thanks. Related: http://stackoverflow.com/questions/2907643/rails-application-settings

  • SQLite REGEXP initializer not working in production on Heroku

    - by morcutt
    I am using this to create a REGEXP in SQLite with rails because SQLite does not support REGEXP. When running this app on Heroku rather than the localhost it does not work. Is the initializer not being run when the app launches? The log files are providing .. 2011-03-04T18:35:36-08:00 app[web.1]: ActiveRecord::StatementInvalid (PGError: ERROR: syntax error at or near "REGEXP" 2011-03-04T18:35:36-08:00 app[web.1]: LINE 1: ... "posts".* FROM "posts" WHERE (message REGEXP '(?... 2011-03-04T18:35:36-08:00 app[web.1]: ^ 2011-03-04T18:35:36-08:00 app[web.1]: : SELECT "posts".* FROM "posts" WHERE (message REGEXP '(?:^|\s+)/(\w+)' and user_id = 1)): Which are similar to what the development files produced if I had deleted the implemented code. It seems as though the REGEXP initializer is not being run at startup.

  • How to get the "#" symbol in the :id into the redirect_to method in Rails

    - by Matthias Günther
    Hello, this is a silly questions but I don't understand, why rails isn't evaluating my string as expected. Here is my problem: I want to redirect to an url in the form ~/:controller/index/#_76 redirect_to :action => "index", :id => '#_76' But I'm getting the url in the form: ~/:controller/index/%25_76 and so my anchor for linking to a certain place in the website isn't working. Can someone please explain me, why rails makes this rendering? I think this hase something to do with url encoding. Again thanks for your help, I'm learning every day a little bit more about rails :).

  • I have the CSS & JS, how do I convert that to erb for my Rails app?

    - by marcamillion
    So I have the foundation of my Rails app, then I went ahead and did the JS and CSS. How do I then take the CSS and JS that I have, and apply it to the app in a 'Rails Way'. i.e. a dynamic way that works nicely. Can you give me some tutorials/articles/resources that I can read up to guide me, please? I have tried the Rails guides, but I find them a bit lacking. Any other good suggestions or tips that might help get me on the right track? Thanks.

  • rails 3 cookies

    - by ralph
    I have a simple app where users type in stuff in a text filed to get various results. I would like a feature where if a user enters something and then closes the browser tab, the next time they come, I can show them their previous/recent searches. This will persist even if they close the whole browser and open it again. I believe this can be done by help of cookies. Are there some good rails3 gems for using cookies or any simple tutorial that could guide me in a direction?

  • .save puts NULL in id field in Rails

    - by mathee
    Here's the model file: class ProfileTag < ActiveRecord::Base def self.create_or_update(options = {}) id = options.delete(:id) record = find_by_id(id) || new record.id = id record.attributes = options puts "record.profile_id is" puts record.profile_id record.save! record end end This gives me the correct print out in my log. But it also says that there's a call to UPDATE that sets profile_id to NULL. Here's some of the output in the log file: Processing ProfilesController#update (for 127.0.0.1 at 2010-05-28 18:20:54) [PUT] Parameter: {"commit"=>"Save", ...} ?[4;36;1mProfileTag Create (0.0ms)?[0m ?[0;1mINSERT INTO `profile_tags` (`reputation_value`, `updated_at`, `tag_id`, `id`, `profile_id`, `created_at`) VALUES(0, '2010-05-29 01:20:54', 1, NULL, 4, '2010-05-29 01:20:54')?[0m ?[4;35;1mSQL (2.0ms)?[0m ?[0mCOMMIT?[0m ?[4;36;1mSQL (0.0ms)?[0m ?[0;1mBEGIN?[0m ?[4;35;1mSQL (0.0ms)?[0m ?[0mCOMMIT?[0m ?[4;36;1mProfileTag Load (0.0ms)?[0m ?[0;1mSELECT * FROM `profile_tags` WHERE (`profile_tags`.profile_id = 4) ?[0m ?[4;35;1mSQL (1.0ms)?[0m ?[0mBEGIN?[0m ?[4;36;1mProfileTag Update (0.0ms)?[0m ?[0;1mUPDATE `profile_tags` SET profile_id = NULL WHERE (profile_id = 4 AND id IN (35)) ?[0m I'm not sure I understand why the INSERT puts the value into profile_id properly, but then it sets it to NULL on an UPDATE. If you need more specifics, please let me know. I'm thinking that the save functionality does many things other than INSERTs into the database, but I don't know what I need to specify so that it will properly set profile_id.

  • Rails: How to toggle a boolean field from a view?

    - by sscirrus
    Very simple question. I have a boolean field called "saved" in my database. I want to toggle this field by clicking on a text link that changes from "Save" to "Unsave" depending on the situation, and updates my "Customer" table with 0 or 1. I imagine Javascript may be a way to go for this but I am not experienced enough (yet!) in Javascript to know how to code it. What is the best way to approach this problem, and how can I find the code I would need to drop into my view to make this toggle work? Thank you very much.

  • Rails 3 query in multiple date ranges

    - by NeoRiddle
    Suppose we have some date ranges, for example: ranges = [ [(12.months.ago)..(8.months.ago)], [(7.months.ago)..(6.months.ago)], [(5.months.ago)..(4.months.ago)], [(3.months.ago)..(2.months.ago)], [(1.month.ago)..(15.days.ago)] ] and a Post model with :created_at attribute. I want to find posts where created_at value is in this range, so the goal is to create a query like: SELECT * FROM posts WHERE created_at BETWEEN '2011-04-06' AND '2011-08-06' OR BETWEEN '2011-09-06' AND '2011-10-06' OR BETWEEN '2011-11-06' AND '2011-12-06' OR BETWEEN '2012-01-06' AND '2012-02-06' OR BETWEEN '2012-02-06' AND '2012-03-23'; If you have only one range like this: range = (12.months.ago)..(8.months.ago) we can do this query: Post.where(:created_at => range) and query should be: SELECT * FROM posts WHERE created_at BETWEEN '2011-04-06' AND '2011-08-06'; Is there a way to make this query using a notation like this Post.where(:created_at => range)? And what is the correct way to build this query? Thank you

  • Is there an API for listing queues and exchanges on RabbitMQ?

    - by parsenome
    I've looked quite a bit, but I haven't been able to find a good programmatic way to list the queues on a RabbitMQ server. This is important because I need to clean up my queues and exchanges when I'm done with them. I don't always have a good "done" event that can be used to trigger a cleanup, so I'd like to do it with more of a garbage collection model. If I can list the queues, I can verify that the objects that they're related to shouldn't be producing more entries and clean them up. I know I can use rabbitmqctl to do it, but that needs elevated privileges. Since I haven't been able to find a way to list the queues programmatically, I've been keeping a list of names in the database. That works, but it's ugly.

  • Rails ActionCaching with Memcached fragment hit but action gets called anyway

    - by baldtrol
    Hi stackoverflow. I'm running into something strange. I'm using memcached with a caches_action setup. I'm doing this in 4 different controllers. In two of them, it works flawlessly (so far), though admittedly those two controllers are less complicated than the two in which it doesn't seem to work. I'm doing something like this: caches_action :index, :expires_in => 6.hours, :cache_path => Proc.new {|controller| controller.send(:generate_cache_path) }, :layout => false, :if => Proc.new { |c| c.request.format.js? } The intention behind the above is to cache some results that are dependent on the params. my :generate_cache_path method just takes into account some params and session vars and creates a unique key for memcached. I can see in memcached -vv that this is working. What's weird is that I get my request from the rails app for a given key, and I see memcached (with -vv) get the request and send back the response. But then my action runs anyway, and a new value is then set for the same key, even when all the same params are given. I can watch it happen. In the controllers where everything is working, the request is made for the fragment, it gets it, and the action in the controller is halted, and the fragment is passed back. These lines come from the exact same request: Cached fragment hit: views/items/?page=1&rp=10&srtn=created_at&srto=DESC.js And then: Cached fragment miss: views/items/?page=1&rp=10&srtn=created_at&srto=DESC.js I don't know what to make of it, or if I'm doing something stupid. Any help or ideas where I could start looking for trouble would be greatly appreciated.

  • Counting distinct and duplicate attribute values in an array

    - by keruilin
    I have an array of users that's sorted in descending order based on total_points. I need to find the rank of each user in that array. The issue is that more than one user can have the same total points and, thus, the same rank. For example, three users could be in 3rd place with 200 Points. Here's my current code: class Leader < ActiveRecord::Base def self.points_leaders all_leaders = all_points_leaders # returns array of users sorted by total_points in desc order all_leaders_with_rank = [] all_leaders.each do |user| rank = all_leaders.index(user)+1 all_leaders_with_rank << Ldr.new(rank, user) # Ldr is a Struct end return all_leaders_with_rank end end How must I modify the code so that the correct rank is returned, and not just the value of the index position?

  • Help debugging Apache, Passenger and Rails problem

    - by Matt Dressel
    We have an environment running that uses Apache, Passenger and rails. The system is handling most request normally, yet certain requests do not make it to the rails application. For instance, a request to /books is successful, but /books/1 hits apache and passenger, but does not even make it to rails. We set the apache log level to debug and the passenger log level to 3 so that we could monitor all incoming requests. We could see each request coming through and even the /books/1 request is being handled by passenger. But it never gets to rails. Is there any way to determine where the request goes between Passenger and rails or where debugging information might live? Has anyone ever seen any problems with passenger spawning or queuing? We have spawning set to conservative. Also, we have had some permission/ownership problems in the past, so I am not ruling this out yet. Thanks in advance
