  • Rails: Passing new child object placeholder (build) to parent view

    - by Meltemi
    I've got 2 classes of objects... Magician has_many Rabbits and Rabbit belongs_to Magician. When viewing a Magician (show.html) I'd like to list all the associated Rabbits and then have some blank fields with a submit button to add a new Rabbit. To do so I build a new rabbit (associated to the current magician) in the Magician's show method (below). Edit2: found way to make it work but not sure if it's the "Rails way"? see comments inline (below): If I build the rabbit in Magician's show method then when show is rendered an empty (and invalid) rabbit ends the list before the new rabbit form fields are then shown. If I build it in the view itself then everything works & renders correctly. I was led to believe that we should not be doing this type of stuff in the view...if so, what's the proper way to address this? #/app/controllers/magicians_controller.rb class MagiciansController < ApplicationController respond_to :html, :json def show @magician = Magician.find(params[:id]) @rabbit = @magician.rabbits.build # <=== build here and empty rabbit gets # included in @magician.rabbits when they're rendered... # but is NOT included in @magician.rabbits.count for some reason?!?!? respond_with(@magician) end ... end #view/magicians/show.html.haml %p %b Name: = @magician.name %h2 Rabbits = "There are #{pluralize(@magician.rabbits.count, "rabbit")}" = render @magician.rabbits, :target => @magician %h2 Add a rabbit: - @rabbit = @clown.rabbits.build -# <=== build here and everything SEEMS to work = render :partial =>"rabbits/form", :locals => { :parent => @magician, :foreign_key => :magician_id, :flash => flash } Edit1: Adding generated html from partial as per request: <p> <b>Rabbit:</b> <b>Color:</b> | <b>ID:</b> <a href="/magicians/2/rabbits" data-confirm="Sure? A bunny will die" data-method="delete" rel="nofollow">Kill Rabbit</a> </p> And I suppose you probably want to see the partial that generates this: %p %b Rabbit: = rabbit.name %b Color: = rabbit.color | %b ID: = rabbit.id = link_to("Kill Rabbit", [target, rabbit], :method => :delete, :confirm => "Sure? A bunny will die")

  • Winform without .NET framework ?

    - by Karthick
    Hi, I have to create few forms and give it as direct EXE (instead of installer, which installs .NET framework, which the end user is not happy, they want something they can directly open and work). I know it can be done as web, but am looking for winforms? Please suggest which tool/technology can handle this? Thanks, Karthick

  • will_paginate with named_scopes

    - by Lowgain
    I'm using will_paginate for pagination, which has been working well so far, except for this one thing. If I try to paginate a scope, for instance class User < ActiveRecord::Base named_scope :scope, lambda { etc } end User.scope.paginate({:page => params[:page], :per_page => 10}) That will tell me paginate is an undefined method. I'd rather not have to use a second solution for only this scope, is there something I can do here?

  • How can I provide an ASP.NET Forms Authentication UX while using Active Directory Role and Authentic

    - by Nate Bross
    Is it possible to use this Role Provider AspNetWindowsTokenRoleProvider with ASP.NET FORMS Authentication (via this MembershipProvider System.Web.Security.ActiveDirectoryMembershipProvider)? It seems to only work with <authentication mode="Windows">, is it possible to use it with FORMS? background -- The objective here is to provide an ASP.NET Forms UX while using Active Directory as the back-end authentication system. If there is another, easy way to do this using built-in technologies, that's great and I'd like to hear about that as well.

  • What does this code do?

    - by Senthil
    I found this in Ryan Bates' railscast site, but not sure how it works. #models/comment.rb def req=(request) self.user_ip = request.remote_ip self.user_agent = request.env['HTTP_USER_AGENT'] self.referrer = request.env['HTTP_REFERER'] end #blogs_controller.rb def create @blog = Blog.new(params[:blog]) @blog.req = request if @blog.save ... I can sort of understand what he is doing. But am confused with the req=(request) line. Any help is appreciated. Thanks

  • Making a COM dll to be invoked from c#, HRESULT error handling?

    - by Daniel
    I'm making a COM interface that c# will be using, however i am wondering how i am to check for errors and exception handling on the c# end as at the moment i am just returning a HRESTULT or bool for most methods. But several things can go wrong in some of these methods and returning a E_FAIL just doesn't cut it. What can i do in order to return more information? Can i make a HRESULT of my own?

  • ASP.NET csv excel issue with strange characters

  • Creating an empty Drawable in Android

    - by Kai
    Creating a Drawable that is completely empty seems like a common need, as a place holder, initial state, etc., but there doesn't seem to be a good way to do this... at least in XML. Several places refer to the system resource @android:drawable/empty but as far as I can tell (i.e., it's not in the reference docs, and aapt chokes saying that it can't find the resource) this doesn't exist. Is there a general way of referencing an empty Drawable, or do you end up creating a fake empty PNG for each project?

  • NSDocument Subclass not closed by NSWindowController?

    - by Nathan Douglas
    Okay, I'm fairly new to Cocoa and Objective-C, and to OOP in general. As background, I'm working on an extensible editor that stores the user's documents in a package. This of course required some "fun" to get around some issues with NSFileWrapper (i.e. a somewhat sneaky writing and loading process to avoid making NSFileWrappers for every single document within the bundle). The solution I arrived at was to essentially treat my NSDocument subclass as just a shell -- use it to make the folder for the bundle, and then pass off writing the actual content of the document to other methods. Unfortunately, at some point I seem to have completely screwed the pooch. I don't know how this happened, but closing the document window no longer releases the document. The document object doesn't seem to receive a "close" message -- or any related messages -- even though the window closes successfully. The end result is that if I start my app, create a new document, save it, then close it, and try to reopen it, the document window never appears. With some creative subclassing and NSLogging, I managed to figure out that the document object was still in memory, and still attached to the NSDocumentController instance, and so trying to open the document never got past the NSDocumentController's "hmm, currently have that one open" check. I did have an NSWindowController and NSDocumentController instance, but I've purged them from my project completely. I've overridden nearly every method for NSDocument trying to find out where the issue is. So far as I know, my Interface Builder bindings are all correct -- "Close" in the main menu is attached to "performClose:" of the First Responder, etc, and I've tried with fresh unsullied MainMenu and Document xibs as well. I thought that it might be something strange with my bundle writing code, so I basically deleted it all and started from scratch, but that didn't seem to work. I took out my init method overrides, and that didn't help either. I don't have the source of any simple document apps here, so I didn't try the next logical step (to substitute known-working code for mine in the readfromurl and writetourl methods). I've had this problem for about sixteen hours of uninterrupted troubleshooting now, and needless to say, I'm at the end of my rope. If I can't figure it out, I guess I'm going to try the project from scratch with a lot more code and intensity based around the bundle-document mess. Any help would be greatly appreciated.

  • Blackberry Player, custom data source

    - by Alex
    Hello I must create a custom media player within the application with support for mp3 and wav files. I read in the documentation i cant seek or get the media file duration without a custom datasoruce. I checked the demo in the JDE 4.6 but i have still problems... I cant get the duration, it return much more then the expected so i`m sure i screwed up something while i modified the code to read the mp3 file locally from the filesystem.

  • Rails find over multiple models

    - by kgb
    I think I'm missing something very obvious and its making my brain hurt. class User < ActiveRecord::Base has_one :profile class Profile < ActiveRecord::Base has_one :user belongs_to :team I have a partial that loops through the users and print some basic info, I'm using this partial in my team show page. I had originally written this to return users who's profiles were a member of a team. def show @team = Team.find_by_id(params[:id]) @profiles= Profile.find(:all, :conditions => ['team_id = ?', @team.id]) @users = User.find_by_id(@profiles.user_id) end But quickly realized @profiles was an array, and it looks messy as hell. Stuck as to what my find should look like to select all User who have a profile that is a member of a team. The partial that is working elsewhere for displaying users looks like this <% for user in @users%> <table> <tr> <td> <%= image_tag user.profile.picture.url %> </td> <td> <a href="/users/<%= user.id %>"><%= user.login %></a> </td> <td> <%= user.profile.first_name %> <%= user.profile.second_name %> </td> <td> <%= user.profile.status %> </td> </tr> </table> <% end %> Development log output with updated show and relationships Processing TeamsController#show (for 127.0.0.1 at 2010-03-30 22:06:31) [GET] Parameters: {"id"=>"1"} User Load (1.3ms) SELECT * FROM "users" WHERE ("users"."id" = 3) LIMIT 1 Team Load (1.0ms) SELECT * FROM "teams" WHERE ("teams"."id" = 1) Rendering template within layouts/main Rendering teams/show Completed in 75ms (View: 11, DB: 2) | 200 OK [http://localhost/teams/1]

  • System.Net.Dns.GetHostAddresses("")

    - by dbasnett
    Yesterday s**ked, and today ain't (sic) looking better. I have an application I have been working on and it can be slow to start when my ISP is down because of DNS. My ISP was down for 3 hours yesterday, so I didn't think much about this piece of code I had added, until I found that it is always slow to start. This code is supposed to return your IP address and my reading of the link suggests that should be immediate, but it isn't, at least on my machine. Oh, and yesterday before the internet went down, I upgraded (oymoron) to XP SP3, and have had other problems. So my questions / request: 1. Am I doing this right? 2. If you run this on your machine does it take 39 seconds to return your IP address? It does on mine. One other note, I did a packet capture and the first request did NOT go on the wire, but the second did, and was answered quickly. So the question is what happened in XP SP3 that I am missing, besides a brain. One last note. If I resolve a FQDN all is well.
