• Problem running Thinking Sphinx with Rails 2.3.5

  - by benoror

  Hi, I just installed Sphinx (distro: archlinux) downloading the source. Then I installed "Thinking Sphinx" plugin for Rails. I followed the official page setup and this Screencast from Ryan Bates, but when I try to index the models it gives me this error: $ rake thinking_sphinx:index (in /home/benoror/Dropbox/Proyectos/cotizahoy) Sphinx cannot be found on your system. You may need to configure the following settings in your config/sphinx.yml file: * bin_path * searchd_binary_name * indexer_binary_name For more information, read the documentation: http://freelancing-god.github.com/ts/en/advanced_config.html Generating Configuration to /home/benoror/Dropbox/Proyectos/cotizahoy/config/development.sphinx.conf sh: indexer: command not found I tried starting the daemon manually (/usr/bin/sphinx-searchd), changing the config/sphinx.yml file: devlopment: searchd_binary_name: sphinx-searchd indexer_binary_name: sphinx-indexer But it shows the same error, any ideas ?

• PHP file download header

  - by skidding

  I have developed a small download system in PHP, where files are downloaded through a proxy file. When I had to do this before, I just redirected by changing the location header; which is not what I want to do now. So, obviously, the first issue that appeared is what kind of header must I set. First of all, Content-Disposition is set as "attachment", so this is good, but I can't seem to get around Content-Type. I need to set it to fit all possible files that might be downloaded through this system. I don't know how to detect the file header automatically, and I'm trying to aviod a GIANT switch. What are my options? Thanks!

• Memory efficient way of inserting an array of objects with Core Data

  - by randombits

  I'm working on a piece of code for an iPhone application that fetches a bunch of data from a server and builds objects from it on the client. It ends up creating roughly 40,000 objects. They aren't displayed to the user, I just need to create instances of NSManagedObject and store them to persistent storage. Am I wrong in thinking that the only way to do this is to create a single object, then save the context? is it best to create the objects all at once, then somehow save them to the context after they're created and stored in some set or array? If so, can one show some example code for how this is done or point me in the direction to code where this is done? The objects themselves are relatively straight forward models with string or integer attributes and don't contain any complex relationships.

• MVC2 jQuery Validation & Custom Business Objects

  - by durilai

  I have an application that was built with MVC1 and am in the process of updating to MVC2. I have a custom DLL and BLL, of which the model objects are custom business objects that reside in a separate class library. I was using this validation library in MVC1, which worked great. It worked great, but I want to eliminate the extra plugins and use what is available. Rather than use the Enterprise Library validation attributes I have converted to using DataAnnotations and want to use jQuery validation as the client side validation. My questions are: 1) Is the MicrosoftMvcJQueryValidation JS file still required, where do I download. 2) How to you automate the validation to views that do not have models, IE Membership sign in page? 3) How to you add model errors in a custom business layer. Thanks for any help or guidance.

• Remove all html tags from attributes in rails

  - by Hock

  I have a Project model and it has some text attributes, one is summary. I have some projects that have html tags in the summary and I want to convert that to plain text. I have this method that has a regex that will remove all html tags. def strip_html_comments_on_data self.attributes.each{|key,value| value.to_s.gsub!(/(<[^>]+>|&nbsp;|\r|\n)/,"")} end I also have a before_save filter before_save :strip_html_comments_on_data The problem is that the html tags are still there after saving the project. What am I missing? And, is there a really easy way to have that method called in all the models? Thanks, Nicolás Hock Isaza

• Screen Capture Under Win7 of JOGL Applet

  - by binarybug

  Hi I'm trying to take a screen shot of an applet running inside a browser. The applet is using JOGL (OpenGL for Java) to display 3D models. (1) The screen shots always come out either black or white.The current solution uses the usual GDI calls. Screen shots of applets not running OpenGL are fine. A few examples of JOGL apps can be found here https://jogl-demos.dev.java.net/ (2) Another thing I'm trying to achieve is to get the scrollable area inside the screen shot as well. I found this code on the internet which works fine except for the 2 issues mentioned above. import win32gui as wg import win32ui as wu import win32con def copyBitMap(hWnd, fname): wg.SetForegroundWindow(hWnd) cWnd = wu.CreateWindowFromHandle(hWnd) rect = cWnd.GetClientRect() (x,y) = (rect[2] - rect[0], rect[3] - rect[1]) hsrccDc = wg.GetDC(hWnd) hdestcDc = wg.CreateCompatibleDC(hsrccDc) hdestcBm = wg.CreateCompatibleBitmap(hsrccDc, x, y) wg.SelectObject(hdestcDc, hdestcBm.handle) wg.BitBlt(hdestcDc, 0, 0, x, y, hsrccDc, rect[0], rect[1], win32con.SRCCOPY) destcDc = wu.CreateDCFromHandle(hdestcDc) bmp = wu.CreateBitmapFromHandle(hdestcBm.handle) bmp.SaveBitmapFile(destcDc, fname)

• how many fps can iPhone's UIGetScreenImage() actually do?

  - by M Katz

  Now that Apple is officially allowing UIGetScreenImage() to be used in iPhone apps, I've seen a number of blogs saying that this "opens the floodgates" for video capture on iPhones, including older models. But I've also seen blogs that say the fastest frame rate they can get with UIGetScreenImage() is like 6 FPS. Can anyone share specific frame-rate results you've gotten with UIGetScreenImage() (or other approved APIs)? Does restricting the area of the screen captured improve frame rate significantly? Also, for the wishful thinking segment of today's program, does anyone have pointers to code/library that uses UIGetScreenImage() to capture video? For instance, I'd like an API something like Capture( int fps, Rect bounds, int durationMs ) that would turn on the camera and for the given duration record a sequence of .png files at the given frame rate, copying from the given screen rect.

• Play! - Expecting a stack map frame in method controllers

  I am using the Security module for my Play! application and had it working at one point, but for some reason I did something to make it stop working. I am getting the following errors: Execution exception VerifyError occured : Expecting a stack map frame in method controllers.Secure$Security.authentify(Ljava/lang/String;Ljava/lang/String;)Z at offset 33 In {module:secure}/app/controllers/Secure.java (around line 61) I saw the post below, but, even though I am using Java 7, it looks like Play! works ok with 7 now.

• Rack rSpec Controller Tests with Rack Middleware issue

  - by Roman Gonzalez

  Howdy, I'm having big trouble testing with rSpec's controller API. Right now I'm using a middleware authentication solution (Warden), and when I run the specs, the proxy added by the middleware is not there, and all the authentication tests are throwing NilPointerExceptions all over the place. It seems rSpec is not adding the middleware to the final app on purpose, and I would like to know if there is a way to monkey patch rSpec in order to make that go. I already tested the whole thing with cucumber, however this is a refactoring of an old authentication version and there is several Controller tests that depend on authentication logic in order to work. Thanks in advance.

• Odd Drag and drag bug in nested attributes Rails

  - by Senthil

  I've got this weird bug when trying to use drag and drag for two models (one nested within another). I've a category model which has many apps. In my category index page, I tried use "content_tag_for" to sort categories and apps within each category. But for some odd reason only the first element has drag, drop enabled. I can drag and drop categories all I want, but I can't drag the app in the second category, just the first category. Copy and paste gets ridiculously hopeless with HAML, so here's a Pastie instead. I made a sample app on heroku for you to check out here. Drag and drag work for both category and app, so I'm guessing it has to do something with the ul or li. Any help is appreciated. Thanks.

• Using fields from an association (has_one) model with formtastic in rails

  - by subprime

  I searched and tried a lot, but I can't accomplish it as I want.. so here's my problem.

• MVVM/ViewModels and handling Authorization

  - by vdh_ant

  Hey guys Just wondering how how people handle Authorization when using MVVM and/or View Models. If I wasn't using VM's I would be passing back the Model and it would have a property which I could check if a user can edit a given object/property but when using MVVM I am disconnecting myself from the business object... and thus doen't know what the security should be any more. Is this a case where the mapper should be aware of the Authorization that is in place and don't copy across the data if the Authorization check fails. If this was the case I am guessing that the mapper would have to see some properties on the VM to let the interface know which fields are missing data because of the Authorization failure. If this does occur within the mapper, how does this fit in with things like AutoMapper, etc. Cheers Anthony

• Axapta 2009 WCF service

  - by Rogue101

  I am trying to add a service reference to axapta 2009. All is working well, its a simple web method(external webservice) that gets executed on the server tier(necessary, otherwise clr interop error) But I've ran into the following problems : is it possible to close the proxy one way or another? Because this option is not available in the generated service object in AX (only the webmethods and a tostring). at a certain moment, i ran into a service with faulted state. Normally, you create the service object again, but this didnt solve anything, until i restarted the AOS. Is this normal behaviour? Is the service object cached or something like that on server side? Thx in advance.

• Dynamic attributes with Rails and Mongoid

  - by japancheese

  Hello, I'm learning MongoDB through the Mongoid Ruby gem with Rails (Rails 3 beta 3), and I'm trying to come up with a way to create dynamic attributes on a model based on fields from another model, which I thought a schema-less database would be a good choice for. So for example, I'd have the models: class Account include Mongoid::Document field :name, :type => String field :token, :type => String field :info_needed, :type => Array embeds_many :members end class Member include Mongoid::Document embedded_in :account, :inverse_of => :members end I'm looking to take the "info_needed" attribute of the Account model and created dynamic attributes on the Member model based on what's inside. If club.info_needed was ["first_name", "last_name"], I'm trying to create a form that would save first_name and last_name attributes to the Member model. However, upon practice, I just keep getting "undefined method first_name=" errors on the Member model when trying to do this. I know MongoDB can handle dynamic attributes per record, but how can I get Mongoid to do this without an undefined method error?

• How to display and update data in MVC2

  - by Picflight

  Table Product Product Id Product Name Table ProductSupplier ProductSupplierId ProductId SupplierId Table Supplier SupplierId SupplierName I have the above 3 tables in my database, ProductSupplier is the lookup table. Each Product can have many suppliers. I am using Entity Framework. Using Web Forms it was fairly easy to display a Product on a web page and bind a repeater with the suppliers information. Also, with Web Forms it was easy to Add new Product and suppliers, the linkage seemed easy. How do you do this sort of functionality in MVC? In the Create View below, I want to be able to Add the Supplier as well. Is there a better approach that I might be missing here? This is how I did it with Web Forms. Beyond the code below I am totally lost. I can show data in a list and also display the Suppliers for each Product, but how do I Add and Edit. Should I break it into different views? With Web Forms I could do it all in one page. namespace MyProject.Mvc.Models { [MetadataType(typeof(ProductMetaData))] public partial class Product { public Product() { // Initialize Product this.CreateDate = System.DateTime.Now; } } public class ProductMetaData { [Required(ErrorMessage = "Product name is required")] [StringLength(50, ErrorMessage = "Product name must be under 50 characters")] public object ProductName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } public class ProductFormViewModel { public Product Product { get; private set; } public IEnumerable<ProductSupplier> ProductSupplier { get; private set; } public ProductFormViewModel() { Product = new Product(); } public ProductFormViewModel(Product product) { Product = product; ProductSupplier = product.ProductSupplier; } } } ProductRepository public Product GetProduct(int id) { var p = db.Product.FirstOrDefault(por => por.ProductId == id); p.ProductSupplier.Attach(p.ProductSupplier.CreateSourceQuery().Include("Product").ToList()); return p; } Product Create View <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MyProject.Mvc.Models.ProductFormViewModel>" %> <%= Html.ValidationSummary("Please correct the errors and try again.") %> <% using (Html.BeginForm()) {%> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.ProductId) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.ProductId) %> <%= Html.ValidationMessageFor(model => model.Product.ProductId) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.ProductName) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.ProductName) %> <%= Html.ValidationMessageFor(model => model.Product.ProductName) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.Description) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.Description) %> <%= Html.ValidationMessageFor(model => model.Product.Description) %> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %>

• Rails User-Profile model challenges

  - by Craig

  I am attempting to create an enrollment process similar to SO's: route to an OpenID provider provider returns the user's information to the UsersController (a guess) UsersController creates user, then routes to the ProfilesController's new or edit action. For now, I'm simply trying to create the user, then route to the ProfilesController's new or edit action (not sure which I should be using). Here's what I have thus far: Models: class User < ActiveRecord::Base has_one :profile end class Profile < ActiveRecord::Base belongs_to :user end Routes: map.resources :users do |user| user.resource :profile end new_user_profile GET /users/:user_id/profile/new(.:format) {:controller=>"profiles", :action=>"new"} edit_user_profile GET /users/:user_id/profile/edit(.:format) {:controller=>"profiles", :action=>"edit"} user_profile GET /users/:user_id/profile(.:format) {:controller=>"profiles", :action=>"show"} PUT /users/:user_id/profile(.:format) {:controller=>"profiles", :action=>"update"} DELETE /users/:user_id/profile(.:format) {:controller=>"profiles", :action=>"destroy"} POST /users/:user_id/profile(.:format) {:controller=>"profiles", :action=>"create"} users GET /users(.:format) {:controller=>"users", :action=>"index"} POST /users(.:format) {:controller=>"users", :action=>"create"} new_user GET /users/new(.:format) {:controller=>"users", :action=>"new"} edit_user GET /users/:id/edit(.:format) {:controller=>"users", :action=>"edit"} user GET /users/:id(.:format) {:controller=>"users", :action=>"show"} PUT /users/:id(.:format) {:controller=>"users", :action=>"update"} DELETE /users/:id(.:format) {:controller=>"users", :action=>"destroy"} Controllers: class UsersController < ApplicationController # generate new-user form def new @user = User.new end # process new-user-form post def create @user = User.new(params[:user]) if @user.save redirect_to new_user_profile_path(@user) ... end end # generate edit-user form def edit @user = User.find(params[:id]) end # process edit-user-form post def update @user = User.find(params[:id]) respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' format.html { redirect_to(users_path) } format.xml { head :ok } ... end end end class ProfilesController < ApplicationController before_filter :get_user def get_user @user = User.find(params[:user_id]) end # generate new-profile form def new @user.profile = Profile.new @profile = @user.profile end # process new-profile-form post def create @user.profile = Profile.new(params[:profile]) @profile = @user.profile respond_to do |format| if @profile.save flash[:notice] = 'Profile was successfully created.' format.html { redirect_to(@profile) } format.xml { render :xml => @profile, :status => :created, :location => @profile } ... end end end # generate edit-profile form def edit @profile = @user.profile end # generate edit-profile-form post def update @profile = @user.profile respond_to do |format| if @profile.update_attributes(params[:profile]) flash[:notice] = 'Profile was successfully updated.' # format.html { redirect_to(@profile) } format.html { redirect_to(user_profile(@user)) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @profile.errors, :status => :unprocessable_entity } end end end Edit-User View: ... <% form_for(@user) do |f| %> ...

• Apache - Tomcat ProxyPass VirtualHost - Context Path

  Hi, I have a problem configuring apache tomcat ProxyPass directive for two applications that have two different Contaxt Pathes in tomcat. The tomcat is running behind an apache and I use the apache to proxy path the requests to tomcat. In apache I want to access both application via a hostname instead of a context path. Scenario: tomcat https://domain:8443/app1 https://domain:8443/app2 in tomcat the applications have the context path app1 and app2 in apache I want to enable both application as follow: https://app1.host/ https://app2.host/ In apache I have created a configuration for each domain: ProxyPass / https://localhost:8443/app1 ProxyPassReverse / https://localhost:/8443/app1 The strange thing is app1 is only available through apache using the context path: https://app1.host/app1 Is it possible to realize such a setup with apache ProxyPass module?

• Django app that can provide user friendly, multiple / mass file upload functionality to other apps

  - by hopla

  Hi, I'm going to be honest: this is a question I asked on the Django-Users mailinglist last week. Since I didn't get any replies there yet, I'm reposting it on Stack Overflow in the hope that it gets more attention here. I want to create an app that makes it easy to do user friendly, multiple / mass file upload in your own apps. With user friendly I mean upload like Gmail, Flickr, ... where the user can select multiple files at once in the browse file dialog. The files are then uploaded sequentially or in parallel and a nice overview of the selected files is shown on the page with a progress bar next to them. A 'Cancel' upload button is also a possible option. All that niceness is usually solved by using a Flash object. Complete solutions are out there for the client side, like: SWFUpload http://swfupload.org/ , FancyUpload http://digitarald.de/project/fancyupload/ , YUI 2 Uploader http://developer.yahoo.com/yui/uploader/ and probably many more. Ofcourse the trick is getting those solutions integrated in your project. Especially in a framework like Django, double so if you want it to be reusable. So, I have a few ideas, but I'm neither an expert on Django nor on Flash based upload solutions. I'll share my ideas here in the hope of getting some feedback from more knowledgeable and experienced people. (Or even just some 'I want this too!' replies :) ) You will notice that I make a few assumptions: this is to keep the (initial) scope of the application under control. These assumptions are of course debatable: All right, my idea's so far: If you want to mass upload multiple files, you are going to have a model to contain each file in. I.e. the model will contain one FileField or one ImageField. Models with multiple (but ofcourse finite) amount of FileFields/ ImageFields are not in need of easy mass uploading imho: if you have a model with 100 FileFields you are doing something wrong :) Examples where you would want my envisioned kind of mass upload: An app that has just one model 'Brochure' with a file field, a title field (dynamically created from the filename) and a date_added field. A photo gallery app with models 'Gallery' and 'Photo'. You pick a Gallery to add pictures to, upload the pictures and new Photo objects are created and foreign keys set to the chosen Gallery. It would be nice to be able to configure or extend the app for your favorite Flash upload solution. We can pick one of the three above as a default, but implement the app so that people can easily add additional implementations (kinda like Django can use multiple databases). Let it be agnostic to any particular client side solution. If we need to pick one to start with, maybe pick the one with the smallest footprint? (smallest download of client side stuff) The Flash based solutions asynchronously (and either sequentially or in parallel) POST the files to a url. I suggest that url to be local to our generic app (so it's the same for every app where you use our app in). That url will go to a view provided by our generic app. The view will do the following: create a new model instance, add the file, OPTIONALLY DO EXTRA STUFF and save the instance. DO EXTRA STUFF is code that the app that uses our app wants to run. It doesn't have to provide any extra code, if the model has just a FileField/ImageField the standard view code will do the job. But most app will want to do extra stuff I think, like filling in the other fields: title, date_added, foreignkeys, manytomany, ... I have not yet thought about a mechanism for DO EXTRA STUFF. Just wrapping the generic app view came to mind, but that is not developer friendly, since you would have to write your own url pattern and your own view. Then you have to tell the Flash solutions to use a new url etc... I think something like signals could be used here? Forms/Admin: I'm still very sketchy on how all this could best be integrated in the Admin or generic Django forms/widgets/... (and this is were my lack of Django experience shows): In the case of the Gallery/Photo app: You could provide a mass Photo upload widget on the Gallery detail form. But what if the Gallery instance is not saved yet? The file upload view won't be able to set the foreignkeys on the Photo instances. I see that the auth app, when you create a user, first asks for username and password and only then provides you with a bigger form to fill in emailadres, pick roles etc. We could do something like that. In the case of an app with just one model: How do you provide a form in the Django admin to do your mass upload? You can't do it with the detail form of your model, that's just for one model instance. There's probably dozens more questions that need to be answered before I can even start on this app. So please tell me what you think! Give me input! What do you like? What not? What would you do different? Is this idea solid? Where is it not? Thank you!
