  • if_attribute on declarative authorization. STUCK FOR DAYS!!!

    - by Victor Martins
    I can't seem to find a solution for this problem :s I have a many to many relationship like this: A user has_many organizations through affiliations and vice versa. I'm using declarative organizations and I only want a user to edit a particular organization if he is affiliated and the affiliationtype attribute of affiliation is a particular value. So affiliations has 3 columns , user_id, organization_id and affiliationtype_id I can do: o = Organization.find(:first) o.affiliatons[0].user and get the user now I wish to do this: has_permission_on [:organizations], :to => :edit do if_attribute (...) end That if_attribute should see if the current user is the organization.affiliation[?].user and if the organization.affiliation[?].affiliationtype_id = "3" I hope this is syntax issue ... I really need to get this working. Thanks in advance.

  • Heroku taps push weirdness...

    - by holden
    I have the strangest experience using taps to move data between my machine and heroku. It works fine except that it seems to loose 0s directly behind the decimal place for my geo coordinates. Ie 50.0519322 for some reason gets set to 50.519322... no idea why. When I pull the data from the remote location ie. heroku db:pull... it works fine, all decimal places intact on my machine, however, when i push it back to the remote server it loses these zeros. Especially directly behind the decimal place, though I haven't noticed it elsewhere yet. At first I was storing the lat and lng as simply numeric but refined it to: change_column :places, :lat, :numeric, :precision => 15, :scale => 10 change_column :places, :lng, :numeric, :precision => 15, :scale => 10 With no result, any ideas what's going on? From the console on the remote server i get the lat as being: #<BigDecimal:2aebcc5967c0,'0.50519322E2',18(18)> and my machine as: #<BigDecimal:10232f7c8,'0.50519322E2',12(16)> which is also odd, the second one because it shows up as 50.0519322 when i edit it thru my view but when i do to_f via console it gives me 50.519322

  • Rails Routing Broken In Production - Caching of routes.rb suspected

    - by ming yeow
    Hi folks, i have an urgent problem. Essentially, my routing works on my localhost. But when i deployed this to production, the routes does not seem to work correctly. For example, given a new route "/invites" - sometimes i will get a 404, and sometimes it will work correctly. I suspect there is some caching going on somewhere, but i am not sure. Logs: when a page is not found (when the routes are supposed to be accurate) Processing UsersController#network (for 67.180.78.126 at 2010-06-01 09:59:31) [GET] Parameters: {"id"="new"} ActionController::RoutingError (No route matches "/comm/role_playing_games" with {}): app/controllers/application_controller.rb:383:in prev_page_label' app/controllers/application_controller.rb:238:in log_timed_info' app/controllers/users_controller.rb:155:in network' app/controllers/users_controller.rb:151:in network' app/controllers/application_controller.rb:44:in turn_on_query_caching' app/controllers/application_controller.rb:43:in turn_on_query_caching' app/controllers/application_controller.rb:42:in turn_on_query_caching' app/controllers/application_controller.rb:41:in turn_on_query_caching' app/controllers/application_controller.rb:40:in turn_on_query_caching' app/controllers/application_controller.rb:39:in turn_on_query_caching' haml (3.0.6) lib/sass/plugin/rack.rb:41:in `call' Rendering /mnt/app/releases/20100524233313/public/404.html (404 Not Found)

  • Call child's method or cast parent to child in Rails

    - by Brian
    I have some STI structure like following: class Box has_many :part,:class_name = "Part" end class Part def self.dosomething() end end class TypeA class TypeB assuming we have some codes like boxtypeA = Box.new. I am wondering if there is a way to make boxtypeA.part.dosomething() to call TypeA's method not Part's or TypeB's. I think basically what we need to do is to convert the part to TypeA, how can we achieve that? Thx in advance!

  • How do I add a condition to all ActiveRecords Queries for a particular model?

    - by Kyle West
    I am using the sentient_user gem to have access to the current_user object in my application. I want to override the default ActiveRecordBase queries to scope them to the current user. For instance, I don't want my users looking at, deleting, modifying other user's orders. I feel like I should be able to override a single (or couple) ActiveRecordBase methods to accomplish this, but I don't know which or how. Thanks in advance.

  • Validate a belongs to association in a build situation.

    - by Victor Martins
    I have a Mission model that has_many Task, and the Task belongs_to Mission For security I've made this validation on the Task Model: validates_presence_of :mission_id validates_numericality_of :mission_id But the problem is that when create a Mission and add tasks like this: @mission.tasks.build The validation returns error, because the mission id on the task is null ( the mission wasn't yet created ) If I delete the validation, the Mission and Task is created successfuly, but how can I keep the validation and still have this work? I could do a callback after the save, but I don't think that's right, because I don't want to save Tasks without a mission_id. P.S. I'm hidding my mission field on the form. If I have it visible, it will show the currect mission and everything is ok. But if I hidde it the error happens. <%= f.hidden_field :mission, :label => "Missão" %> Is the form reseting the attributes given by the controller on the new action?

  • vlad the deployer: why do I need a scm folder?

    - by egarcia
    I'm learning to use vlad the deployer and I've got a question. Since I'm still learning I don't know what is pertinent to the question and what isn't, so please bear with me if I'm a little verbose. I've got 2 environments for a new application (test and production) besides my development machine. I've figured out this way to do the initial setup in my vlad.rake: namespace :test task :set set :domain, 'test.myserver.com' end end namespace :production task :set set :domain, 'www.myserver.com' end end This way I can have environment-specific stuff inside the namespaces, and still have shared tasks. For example, this would be the initial setup for test: rake vlad:test:set vlad:setup vlad:update This creates the following folders on my test server: releases/ scm/ shared/ current -> symlink to last release (inside the releases folder) My question is: what's the point of the scm folder? Every time I do vlad:update, the following happens: svn checkout on the scm/ folder above svn export on the /releases/{date} folder update current symlink So scm is a copy of my repository... but then there's an "export" copy of the repository on /releases/{date}. And that is the one used by the application... scm doesn't seem to be used by anyone? Wouldn't I be just fine without the scm folder?

  • Mysql results sorted by list which is unique for each user

    - by ADAM
    Ive got a table of thousands of products and 50 or so authenticated users. These users all show the products on their own web sites and they all require the ability to have them ordered differently. Im guesing i need some kind of seperate table for the orders which contains the product_id, user_id and order column? How do i do this the most efficiently in mysql so as to be very fast, and not slow down if i get millions of products in the database. Is it even wise to do it in mysql or should i be using some kind of other index like solr/lucene? My Product table is called "products" My User table is called "users" A good example of the functionality i need is google search where you can order/supress the results if you are logged in. edit: the product results will be paginated and the users have the authority to edit the products, so its not just ready only

  • Rails: Ajax: Changes Onload

    - by Jay Godse
    Hi. I have a web layout of a for that looks something like this <html> <head> </head> <body> <div id="posts"> <div id="post1" class="post" > <!--stuff 1--> </div> <div id="post2" class="post" > <!--stuff 1--> </div> <!-- 96 more posts --> <div id="post99" class="post" > <!--stuff 1--> </div> </div> </body> </html> I would like to be able to load and render the page with a blank , and then have a function called when the page is loaded which goes in and load up the posts and updates the page dynamically. In Rails, I tried using "link_to_remote" to update with all of the elements. I also tweaked the posts controller to render the collection of posts if it was an ajax request (request.xhr?). It worked fine and very fast. However the update of the blank div is triggered by clicking the link. I would like the same action to happen when the page is loaded so that I don't have to put in a link. Is there a Rails Ajax helper or RJS function or something in Rails that I could use to trigger the loading of the "posts" after the page has loaded and rendered (without the posts)? (If putsch comes to shove, I will just copy the generated JS code from the link_to_remote call and have it called from the onload handler on the body).

  • rails, mysql charsets & encoding: binary

    - by Benjamin Vetter
    Hi, i've a rails app that runs using utf-8. It uses a mysql database, all tables with mysql's default charset and collation (i.e. latin1). Therefore the latin1 tables contain utf-8 data. Sure, that's not nice, but i'm not really interested in it. Everything works fine, because the connection encoding is latin1 as well and therefore mysql does not convert between charsets. Only one problem: i need a utf-8 fulltext index for one table: mysql> show create table autocompletephrases; ... AUTO_INCREMENT=310095 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci But: I don't want to convert between charsets in my rails app. Therefore I would like to know if i could just set config/database.yml production: adapter: mysql >>>> encoding: binary ... which just calls SET NAMES 'binary' when connecting to mySQL. It looks like it works for my case, because i guess it forces mysql to -not- convert between charsets (mySQL docs). Does anyone knows about problems about doing this? Any side-effects? Or do you have any other suggestions? But i'd like to avoid converting my whole database to utf-8. Many Thanks! Benjamin

  • Running a SQL query in rails

    - by Bharat
    Hello I have a rails application where I have to subtract 2 time stamps and display the result on the webpage I have used the following sql statement and I am getting the results. select (julianday(resolutions.created_at)-julianday(tickets.created_at))*24 from tickets,resolutions the value of tickets.created_at is 2010-04-05 18:59:02 which is a time stamp and value of resolutions.created_at is 2010-04-08 08:10:33 Now where do I put this sql so that I can be seen in my webpage. I tired it in the views page with the following but nothing showed up: <% @sql = "select (julianday(resolutions.created_at)-julianday(tickets.created_at))*24 from tickets,resolutions" %> <% @t=(ActiveRecord::Base.connection.execute(@sql)) %> So how do I display it on my webpage? when I perform the above I get the output printed on the webpage as 061.1919444389641(julianday(resolutions.created_at)-julianday(tickets.created_at))*2461.1919444389641 only 61.1919444389641 is supposed to be printed but the query statement is also getting printed.

  • Rails choking on the content of this request because of protect_from_forgery

    - by randombits
    I'm trying to simply test my RESTful API with cURL. Using the following invocation: curl -d "name=jimmy" -H "Content-Type: application/x-www-form-urlencoded" http://127.0.0.1:3000/people.xml -i Rails is dying though: ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): :8:in `synchronize' Looks like it's running this through a protect_from_forgery filter. I thought protect_from_forgery is excluded for non-HTML HTTP POST/PUT/DELETE type requests? This is clearly targeting the XML format. If I pass actual XML content, it works. But my users will be submitting POST data as URL encoded parameters. I know all the various ways I can disable protect_from_forgery but what's the proper way of handling this? I want to leave it on so that when I do have HTML based forms and handle format.html, I don't forget to re-enable it for then. I want users to be able to make HTTP POST requests to my XML-based API though and not get bombarded with this.

  • Rails polymorphic associations, two assoc types in one class

    - by snitko
    Consider a class: class Link < ActiveRecord::Base has_many :link_votes, :as => :vote_subject, :class_name => 'Vote' has_many :spam_votes, :as => :vote_subject, :class_name => 'Vote' end The problem is, when I'm adding a new vote with @link.link_votes << Vote.new the vote_subject_type is 'Link', while I wish it could be 'link_votes' or something like that. Is this an AR limitation or is there a way to workaround this thing? I've actually found one related answer, but I'm not quite sure about what it says: http://stackoverflow.com/questions/1168047/polymorphic-association-with-multiple-associations-on-the-same-model/1764117#1764117

  • Setting a cookie before Javascript Redirection

    - by Jason
    Hello, I have a Rails app where I set a set a session variable the moment a user lands on my site with the referer and the page they hit. Additionally, I have Google Optimizer sending traffic from my homepage to various landing pages. The problem is that I think Google Optimizer is sending users away before the cookie is set. Is that even possible? I believe that the cookie is set from the HTTP Header, which must have fully loaded before Google's Javascript has even loaded. Thanks, Jason

  • I'm using a sequence in Factory Girl to get unique values but I'm getting validation errors

  • Good way to handle inline-edit form using Rails and jQuery

    - by Tim Sullivan
    I have a list of items, being displayed in a series of DIVs. When someone clicks on an "edit" link, I want to replace the div with a form that will let them edit the contents of that item in a nice way. I'm trying to think of the ideal way to handle this. Do I create a hidden edit form for every item in the list, and hook the edit link to reveal it, like this: <div> <a href="#">edit</a> Item One <div id="edit_1202" class="editform">Edit form goes here</div> </div> <div> <a href="#">edit</a> Item Two <div id="edit_2318" class="editform">Edit form goes here</div> </div> Or is there a better way to fetch the data and insert the form's HTML into the right spot? Remember, I'm using jQuery, so I can't use the prototype helpers. Thanks!

  • Form is submitting when the page loads

    - by RailAddict
    I have a really simple Rails app. Basically an article with comments. I want the article page to show the article, comments underneath and then a textbox to write a comment and a submit button to submit it. I got it all working except for one (big) problem. When the page loads.. example.com/article/1 a blank comment is submitted to the database. I fixed that by including "validates_presence_of :body" in the Comment model. But that results in the following image when the page loads: This is my code by the way: def show @place = Article.find(params[:id]) @comment = Article.find(params[:id]).comments.create(params[:comment]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @article } end end and <% form_for([@article, @comment]) do |f| %> <p> <%= f.label :commenter %><br /> <%= f.text_field :commenter %> </p> <p> <%= f.label :body %><br /> <%= f.text_area :body %> </p> <p> <%= f.submit "Create" %> </p> <% end %>

  • Big sinatra problems

    - by Joel M.
    Hi, So I'm having huge trouble with sinatra. Here's what I have: require 'dm-core' DataMapper.setup(:default, ENV['DATABASE_URL'] || 'sqlite3://my.db') class Something include DataMapper::Resource property :id, Serial property :thing, Text property :run_in, Integer property :added_at, DateTime property :to, String def schedule cronify(self.thing+" to "+self.to, "http://url"+self.id.to_s, self.run_in) end def notify text(self.thing, self.to) end end Something.auto_upgrade! The cronify method works. I tested it in irb. Also, the schedule instance method works, I tested it in the console. However, it doesn't work in the route, even though it works in the console. post '/add' do @something = Something.create(blah) #this works fine @something.schedule #this works fine in the console; not in the route. end I've tried everything, from @something.create(blah).schedule (which also works fine in the console, but not in the route), to defining the method cronify inside the sinatra helpers, and even calling cronify directly on the route. Nothing works on the route. What am I doing wrong?
