  • ASP.NET MVC: Html.Actionlink() generates empty link.

    - by wh0emPah
    Okay i'm experiencing some problems with the actionlink htmlhelper. I have some complicated routing as follows: routes.MapRoute("Groep_Dashboard_Route", // Route name "{EventName}/{GroupID}/Dashboard", // url with Paramters new {controller = "Group", action="Dashboard"}); routes.MapRoute("Event_Groep_Route", // Route name "{EventName}/{GroupID}/{controller}/{action}/{id}", new {controller = "Home", action = "Index"}); My problem is generating action links that match these patterns. The eventname parameter is really just for having a user friendly link. it doesn't do anything. Now when i'm trying for example to generate a link. that shows the dashboard of a certain groep. Like: mysite.com/testevent/20/Dashboard I'll use the following actionlink: <%: Html.ActionLink("Show dashboard", "Group", "Dashboard", new { EventName_Url = "test", GroepID = item.groepID}, null)%> What my actual result in html gives is: <a href="">Show Dashboard</a> Please bear with me i'm still new at ASP MVC. Could someone tell me what i'm doing wrong? Help would be appreciated!

  • Java Classpath Issues with Webservices(CXF) and Jboss

    - by JohnC
    I am using CXF(which autogenerates my webservices in my pom.xml from my wsdl) with JBoss(eclipse ide), and I am having some trouble accessing the webservice from my web application. I found this resource: http://blog.progs.be/?p=92 but I am having a really hard time using WSDL_LOCATION = cl.getResource( "my/progam/pack/wsdl/myService.wsdl" ); to work properly in my code. I have my wsdls located in src/main/wsdl and have added the following line to the .classpath file: classpathentry kind="src" path="src/main/wsdl" I also created the folders my,program,pack,wsdl and dropped my wsdls into that location, so it is accessible. However, the classloader.getResource call always returns null no matter what. When I specify getResource( "/wsdl/myService.wsdl" ) it does not return null, but I believe it looks at the full file path and not what I need (considering part of the URL contains the path to the wsdl file all the way through the jboss server directory and includes the WEB-INF dir. Is my .classpath file set up incorrectly or am I missing something else? if the WSDL Location is not correct it always throws a ClassCast Exception like so: java.lang.ClassCastException: org.apache.cxf.jaxws.ServiceImpl at javax.xml.ws.Service.(Service.java:81)

  • Reversing Django URLs With Extra Options

    - by Justin Voss
    Suppose I have a URLconf like below, and 'foo' and 'bar' are valid values for page_slug. urlpatterns = patterns('', (r'^page/(?P<page_slug>.*)/', 'myapp.views.someview'), ) Then, I could reconstruct the URLs using the below, right? >>> from django.core.urlresolvers import reverse >>> reverse('myapp.views.someview', kwargs={'page_slug': 'foo'}) '/page/foo/' >>> reverse('myapp.views.someview', kwargs={'page_slug': 'bar'}) '/page/bar/' But what if I change my URLconf to this? urlpatterns = patterns('', (r'^foo-direct/', 'myapp.views.someview', {'page_slug': 'foo'}), (r'^my-bar-page/', 'myapp.views.someview', {'page_slug': 'bar'}), ) I expected this result: >>> from django.core.urlresolvers import reverse >>> reverse('myapp.views.someview', kwargs={'page_slug': 'foo'}) '/foo-direct/' >>> reverse('myapp.views.someview', kwargs={'page_slug': 'bar'}) '/my-bar-page/' However, this throws a NoReverseMatch exception. I suspect I'm trying to do something impossible. Any suggestions on a saner way to accomplish what I want? Named URLs aren't an option, since I don't want other apps that link to these to need to know about the specifics of the URL structure (encapsulation and all that).

  • ASP.NET MVC, areas, routing and a controller factory.

    - by Kieron
    Hi, I've an interesting problem with some routing with an ASP.NET MVC app. I'm building a CMS and I've got a catch-all handler that takes the URL and checks to see if there's some matching content in a database. If so, it displays it, otherwise we get a 404. Now I've got all that working with some test data, I moved on to write a quick admin system. I thought I'd use some of the new Area functionality baked into MVC 2, so I've created an area called Admin with a controller called Home. Now however I have a problem of the default HomeController in the Admin Area is being returned when requesting the application root path. The problem is that there is no other HomeController for the 'root' application (the one hosting all of the areas), instead the root would be redirected to the my catch-all handler and populated from the database. So now the controller factory is returning the best matching controller, which it thinks is the admin area one, what I really need is for it to not match it at all - as it did previously. Apart from renaming the Admin HomeController to something else, is there another solution?

  • Render view to string followed by redirect results in exception

    - by Chris Charabaruk
    So here's the issue: I'm building e-mails to be sent by my application by rendering full view pages to strings and sending them. This works without any problem so long as I'm not redirecting to another URL on the site afterwards. Whenever I try, I get "System.Web.HttpException: Cannot redirect after HTTP headers have been sent." I believe the problem comes from the fact I'm reusing the context from the controller action where the call for creating the e-mail comes from. More specifically, the HttpResponse from the context. Unfortunately, I can't create a new HttpResponse that makes use of HttpWriter because the constructor of that class is unreachable, and using any other class derived from TextWriter causes response.Flush() to throw an exception, itself. Does anyone have a solution for this? public static string RenderViewToString( ControllerContext controllerContext, string viewPath, string masterPath, ViewDataDictionary viewData, TempDataDictionary tempData) { Stream filter = null; ViewPage viewPage = new ViewPage(); //Right, create our view viewPage.ViewContext = new ViewContext(controllerContext, new WebFormView(viewPath, masterPath), viewData, tempData); //Get the response context, flush it and get the response filter. var response = viewPage.ViewContext.HttpContext.Response; //var response = new HttpResponseWrapper(new HttpResponse // (**TextWriter Goes Here**)); response.Flush(); var oldFilter = response.Filter; try { //Put a new filter into the response filter = new MemoryStream(); response.Filter = filter; //Now render the view into the memorystream and flush the response viewPage.ViewContext.View.Render(viewPage.ViewContext, viewPage.ViewContext.HttpContext.Response.Output); response.Flush(); //Now read the rendered view. filter.Position = 0; var reader = new StreamReader(filter, response.ContentEncoding); return reader.ReadToEnd(); } finally { //Clean up. if (filter != null) filter.Dispose(); //Now replace the response filter response.Filter = oldFilter; } }

  • How do I pass a cookie to a Sinatra app using curl?

    - by Brandon Toone
    I'm using the code from the example titled "A Slightly Bigger Example" from this tutorial http://rubylearning.com/blog/2009/09/30/cookie-based-sessions-in-sinatra/ to figure out how to send a cookie to a Sinatra application but I can't figure out how to set the values correctly When I set the name to be "brandon" in the application it creates a cookie with a value of BAh7BiIJdXNlciIMYnJhbmRvbg%3D%3D%0A which is a url encoding (http://ostermiller.org/calc/encode.html) of the value BAh7BiIJdXNlciIMYnJhbmRvbg== Using that value I can send a cookie to the app correctly curl -b "rack.session=BAh7BiIJdXNlciIMYnJhbmRvbg==" localhost:9393 I'm pretty sure that value is a base64 encoding of the ruby hash for the session since the docs (http://rack.rubyforge.org/doc/classes/Rack/Session/Cookie.html) say The session is a Ruby Hash stored as base64 encoded marshalled data set to :key (default: rack.session). I thought that meant all I had to do was base64 encode {"user"=>"brandon"} and use it in the curl command. Unfortunately that creates a different value than BAh7BiIJdXNlciIMYnJhbmRvbg==. Next I tried taking the base64 encoded value and decoding it at various base64 decoders online but that results in strange characters (a box symbol and others) so I don't know how to recreate the value to even encode it. So my question is do you know what characters/format I need to get the proper base64 encoding and/or do you know of another way to pass a value using curl such that it will register as a proper cookie for a Sinatra app?

  • "The image <name> cannot be displayed because it contains errors" when using pchart Render method

    - by christophe-milard
    Hi, I am trying to use the pchart package (over php) to build (and directly display) graphs/charts. At this time, I am just trying to run their provided example (Example1.php), where I just have replaced the final: $Test-Render("example1.png"); by $Test-Stroke(); But When I do this, I get:" The image cannot be displayed because it contains errors" on the browser. If I leave the original "$Test-Render(...)" the generated image is OK. (but not sent) I have read that there is (was?) an issue with mozilla/Firefox browsers regarding images being required twice and the REFER URL, but when I browse at the pchart home page, I can use their "sanboxes" and get the result of my tests directly displayed on my browser (http://pchart.sourceforge.net/demo.php). ... So their must be a way (or a nice work around) to send the generated graphs directely to the browser successfuly. If your answer is to generate the image (i.e. use Render) and then send it afterwards, please but accurate on how to do this (how do I destroy the generated files automaticaly, permissions...) I am new to this, sorry advance if it's obvious...;-)

  • jQuery UI Accordion CSS

    - by ScG
    I am planning to use the jQuery UI Accordion and also the default theme provided I see that the jQuery UI Accordion uses the following classes from this url link text <div class="ui-accordion ui-widget ui-helper-reset"> <h3 class="ui-accordion-header ui-helper-reset ui-state-active ui-corner-top"> <span class="ui-icon ui-icon-triangle-1-s"/> <a href="#">Section 1</a> </h3> <div class="ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom ui-accordion-content-active"> Section 1 content </div> <h3 class="ui-accordion-header ui-helper-reset ui-state-default ui-corner-all"> <span class="ui-icon ui-icon-triangle-1-e"/> <a href="#">Section 2</a> </h3> <div class="ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom"> Section 2 content </div> <h3 class="ui-accordion-header ui-helper-reset ui-state-default ui-corner-all"> <span class="ui-icon ui-icon-triangle-1-e"/> <a href="#">Section 3</a> </h3> <div class="ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom"> Section 3 content </div> </div> I do not want to use the entire CSS from the theme file, just the ones required for the UI Accordion.

  • Help with an AJAX request

    - by sea_1987
    The Problem I am tring to do an ajax request to a PHP script, however I am having a problem getting the data into the format that the PHP is expecting it, the PHP is expecting the data to come in as array within an array something like, Array ( [cv_file] => Array ( [849649717] => Y [849649810] => Y ) [save] => Save CVs ) What have I tried? I have tried in my javascript to create an empty array and use that as the array key, something like this, var cv_file = new Array(); $(".drag_check").draggable({helper:"clone", opacity:"0.5"}); $(".searchPage").droppable({ accept:".drag_check", hoverClass: "dropHover", drop: function(ev, ui) { var droppedItem = ui.draggable.children(); cv_file = ui.draggable.children().attr('name'); var link = ui.draggable.children().attr('name').substr(ui.draggable.children().attr('name').indexOf("[")+1, ui.draggable.children().attr('name').lastIndexOf("]")-8) $.ajax({ type:"POST", url:"/search", data:cv_file+"&save=Save CVs", success:function(){ alert(cv_file) $('.shortList').append('<li><input type="checkbox" value="Y" class="checkbox" name="remove_cv['+link+']"/><a href="/cv/'+link+'">'+link+'</a></li>'); }, error:function() { alert("Somthing has gone wrong"); } }); } }); My Question How can I get the data into the format that the PHP is expecting, I would appreciate any help that anyone can give? Edit On alerting what the poster in the comments suggested I get he following, cv_file[849649717]&save=Save CVs Thank you

  • Django Class Views and Reverse Urls

    - by kalhartt
    I have a good many class based views that use reverse(name, args) to find urls and pass this to templates. However, the problem is class based views must be instantiated before urlpatterns can be defined. This means the class is instantiated while urlpatterns is empty leading to reverse throwing errors. I've been working around this by passing lambda: reverse(name, args) to my templates but surely there is a better solution. As a simple example the following fails with exception: ImproperlyConfigured at xxxx The included urlconf mysite.urls doesn't have any patterns in it mysite.urls from mysite.views import MyClassView urlpatterns = patterns('', url(r'^$' MyClassView.as_view(), name='home') ) views.py class MyClassView(View): def get(self, request): home_url = reverse('home') return render_to_response('home.html', {'home_url':home_url}, context_instance=RequestContext(request)) home.html <p><a href={{ home_url }}>Home</a></p> I'm currently working around the problem by forcing reverse to run on template rendering by changing views.py to class MyClassView(View): def get(self, request): home_url = lambda: reverse('home') return render_to_response('home.html', {'home_url':home_url}, context_instance=RequestContext(request)) and it works, but this is really ugly and surely there is a better way. So is there a way to use reverse in class based views but avoid the cyclic dependency of urlpatterns requiring view requiring reverse requiring urlpatterns...

  • DDD principlers and ASP.NET MVC project design

    - by kaivalya
    Two part questions I have a product aggregate that has; Prices PackagingOptions ProductDescriptions ProductImages etc I have modeled one product repository and did not create individual repositories for any of the child classes. All db operations are handled through product repository. Am I understanding the DDD concept correctly so far? Sometimes the question comes to my mind that having a repository for lets say packaging options could make my life easier by directly fetching a the packaging option from the DB by using its ID instead of asking the product repository to find it in its PackagingOptions collection and give it to me.. Second part is managing the edit create operations using ASP.MVC frame work I am currently trying to manage all add edit remove of these child collections of product through product controller(sound right?). One challenge I am now facing is; If I edit a specific packaging option of product through mydomain/product/editpackagingoption/10 I have access to the id of the packaging option But I don't have the ID of the product it self and this forces me to write a query to first find the product that has this specific packaging option then edit that product and the revelant packaging option. I can do this as all packaging option have their unique ID but this would fail if I have collections that don't have unique ID. That feels very wrong.. The next option I thought of is sending both the product and packaging option IDs on the url like; mydomain/product/editpackagingoption/3/10 But I am not sure if that is a good design either. So I am at a point that I am a bit confused. might be having fundamental misunderstandings around all of this... I would appreciate if you bear with the long question and help me put this together. thanks!

  • Lazy loading of Blob properties of one class

    - by Khosro
    Hi, My class contains "summary" and "title" properties those are Blob and other properties. Code:(I write some part of class) public class News extends BaseEntity{ @Lob @Basic(fetch = FetchType.LAZY) public String getSummary() { return summary; } @Lob @Basic(fetch = FetchType.LAZY) public String getTitle() { return title; } @Temporal(TemporalType.TIMESTAMP) public Date getPublishDate() { return publishDate; } } I instrument this class to lazy load of Blob properties using this class "org.hibernate.tool.instrument.javassist.InstrumentTask". When i write this code to retrieve only summary of new , newsDAO.findByid(1L).getSummary(); Hibernate generates these queries: Hibernate: select news0_.id as id1_, news0_.entityVersion as entityVe2_1_, news0_.publishDate as publish15_1_, news0_.url as url1_ from News news0_ Hibernate: select news_.summary as summary1_, news_.title as title1_ from News news_ where news_.id=? I have two qurestions: 1.I only want to retrieve "summary" property not "title" property,but Hibernate queries show that it also retrieve "title" property,Why this happens(i want to lazy load of "property")? It seems when i load one of Blob property ,Hibernate loads all of them.Why?(This is my main question) 2.Why Hibernate generates two queries for retrieving only "summary" property of news? Khosro.

  • How to forward a 'saved' request stream to another Action within the same controller?

    - by Moe Howard
    We have a need to chunk-up large http requests sent by our mobile devices. These smaller chunk streams are merged to a file on the server. Once all chunks are received we need a way to submit the saved merged request to an another method(Action) within the same controller that will process this large http request. How can this be done? The code we tried below results in the service hanging. Is there a way to do this without a round-trip? //Open merged chunked file FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read); //Read steam support variables int bytesRead = 0; byte[] buffer = new byte[1024]; //Build New Web Request. The target Action is called "Upload", this method we are in is called "UploadChunk" HttpWebRequest webRequest; webRequest = (HttpWebRequest)WebRequest.Create(Request.Url.ToString().Replace("Chunk", string.Empty)); webRequest.Method = "POST"; webRequest.ContentType = "text/xml"; webRequest.KeepAlive = true; webRequest.Timeout = 600000; webRequest.ReadWriteTimeout = 600000; webRequest.Credentials = System.Net.CredentialCache.DefaultCredentials; Stream webStream = webRequest.GetRequestStream(); //Hangs here, no errors, just hangs I have looked into using RedirectToAction and RedirecctToRoute but these methods don't fit well with what we are looking to do as we cannot edit the Request.InputStream (as it is read-only) to carry out large request stream. Thanks, Moe

  • Test Ruby-on-Rails controller with RSpec and different route name

    - by jhwist
    I have a Rails model named Xpmodule with a corresponding controller XpmoduleController. class XpmoduleController < ApplicationController def index @xpmodule = Xpmodule.find(params[:module_id]) end def subscribe flash[:notice] = "You are now subscribed to #{params[:subscription][:title]}" redirect_to :action => :index end end The original intent was to name the model Module which for obvious reasons doesn't work. However I still want to have the URLs look like /module/4711/ therefore I added this to my routes.rb: map.connect '/module/:module_id', :controller => 'xpmodule', :action => 'index' map.connect '/module/:module_id/subscribe', :controller => 'xpmodule', :action => 'subscribe' Now I want to test this controller with Rspec: describe XpmoduleController do fixtures :xpmodules context "index" do it "should assign the current xpmodule" do xpm = mock_model(Xpmodule) Xpmodule.should_receive(:find).and_return(xpm) get "index" assigns[:xpmodule].should be_an_instance_of(Xpmodule) end end end for which I get No route matches {:action=>"index", :controller=>"xpmodule"}. Which of course is sort-of right, but I don't want to add this route just for testing purposes. Is there a way to tell Rspec to call a different URL in get?

  • Paperclip wont save image in rails app

    - by Micke
    Hello stackoverflow. I am trying to use Paperclip with my rails app to add an avatar to a user but it wont save my image when creating the user. This is what the model looks like: class User < ActiveRecord::Base has_attached_file :avatar And the registerform in haml: - form_for :user, @user, :url => { :action => "signup" }, :html => { :multipart => true } do |f| ... ... %li %div{:class => "header"} Profilepicture %div{:class => "input"} = f.file_field :avatar And when i look in the log this is what is being passet to the "signup" action: Parameters: {"commit"=>"Save", "action"=>"signup", "controller"=>"user/register", "user"=>{"name"=>"Micke Lisinge", "birthmonth"=>"07", "password_confirmation"=>"[FILTERED]", "nickname"=>"lisinge", "avatar"=>#<File:/tmp/RackMultipart20100426-3076-1x04oxy-0>, "gen"=>"m", "birthday"=>"23", "password"=>"[FILTERED]", "birthyear"=>"1992", "email"=>"[email protected]"}} [paperclip] Saving attachments. Paperclip says it is saving the template but when i look in the public folder in my app it has created a system but the system folder is empty. So it seems like it isnt saving the picture to the folder. It gets handled by the form and saved in my /tmp folder. Maybe you guys have any tips or know what this problem might be? Thanks in advance, Micke.

  • Navigating between pages in a Facebook Platform iframe application

    - by Jimmy Cuadra
    I'm working on a Facebook Platform application that runs in iframe mode, and I'm having trouble understanding how to navigate between pages within the app. Let's say the first page that is loaded within the iframe at my canvas URL is one.html. Within that page, there is a link to two.html that just changes the source of the iframe and doesn't reload the Facebook chrome. When I do this, all the Facebook fb_sig_* query string parameters that Facebook passes to the original page aren't included, and so two.html has no awareness of the connection to Facebook and no ability to make API calls to generate the content for the page. One possible solution would be to manually extract all the Facebook parameters from one.html and append it to the link to two.html myself. This seems really ugly and I figured there had to be a cleaner way. For reference, my application is written in Perl and uses the WWW::Facebook::API module as a client library. I didn't see anything in it that I can use to easily reconstruct the Facebook parameters for use with links in iframe apps. Another possible solution would be to store all the Facebook parameters in a session on my server on the first page load, and just use the values in that session on subsequent page views. But what happens if the data I've stored no longer matches what Facebook would have sent if it were a completely new request (i.e. something in the user's Facebook session changed)? Is there something obvious I'm missing? What is the standard approach to navigating between pages within an iframe app? Facebook's documentation is atrocious and I haven't been able to find anything that clearly explains how this works. I also realize this wouldn't be an issue with an app using FBML instead of an iframe, but my understanding is that iframe apps are now encouraged over FBML apps, though again this seems ambiguous since so much of Facebook's documentation is outdated and contradictory.

  • How do I dynamically create a document for download in Javascript?

    - by Nelson
    I'm writing some Javascript code that generates an XML document in the client (via Google Earth plugin). I'd like the user to be able to click a button on the page and be prompted to save that XML to a new file. If I were generating the XML server-side this would be easy, just make the button open the link. But the XML is generated client-side. I've come up with a couple of hacks that half-work, inspired in part by this StackOverflow question. But neither completely work. Here's a demo HTML with embedded code: <html><head><script> function getData() { return '<?xml version="1.0" encoding="UTF-8"?><doc>Hello</doc>'; } function dlDataURI() { window.open("data:text/xml;charset=utf-8," + getData()); } function dlWindow() { var w = window.open(); w.document.open(); w.document.write(getData()); w.document.close(); } </script><body> <div onclick="dlDataURI()">Click for Data URL</div> <div onclick="dlWindow()">Click for Window</div> </body></html> The dlDataURI() version works great in Firefox, poorly in Chrome (can't save), and not at all in IE. The Window() version works OK in Firefox and IE, and not well in Chrome (can't save, XML embedded inside HTML). Neither version ever prompts a user download, it always opens a new window trying to display the XML. Is there a good way to do what I want in client side Javascript? I'd like this to work in today's browsers, ideally Firefox, MSIE 8, and Chrome.

  • Google App Engine on Google Apps Domain

    - by Bob Ralian
    I'm having trouble getting my domain pointed to my website hosted with google app engine. Here's the background... take care to separate the concepts of "google apps" (domain hosting, email, etc.) and "google app engine" (website framework). I have a domain that's using Google Apps for Your Domain, let's call it company.com. So my login for my google apps account is [email protected]. I have a different domain that is aliased back to my google apps account, let's call it mycompany.com. It's been successfully aliased and registered with my primary google apps account using the cname method, and has updated mx records. We have a ton of domains, and I only want to use one "google apps" account to maintain them all. Now I have a website I've built using google app engine, and the url is effectively mycompany.appspot.com. I want to get mycompany.com to point to my website that currently resides at mycompany.appspot.com. There's a spot in the google app engine dashboard under application settings where you can add a domain. So I click there and enter mycompany.com and I get an error message saying that domain is not using google apps. If I back up to the page I submitted, there's a note saying I need to register the domain with google apps. So I click the link to do that and enter mycompany.com and I get an error message saying the domain has been registered and is in the process of ownership verification. But that process is already finished. So... what do I do? Does google app engine not support a domain that is only aliased to a primary google apps account? Does mycompany.com need to have its own primary google apps account?

  • ws-xmlrpc claims error on part of service but other clients work fine

    - by mludd
    I've been trying to connect to an rTorrent instance using ws-xmlrpc and it just isn't going too well. Now, the URL I'm using is the same that I've been using when making sure that rTorrent's XMLRPC support is fine (which it appears to be since both a native OS X application and a small python script I threw together appear to be able to talk to it just fine without any errors). However, when I try using ws-xmlrpc to connect I get org.apache.xmlrpc.XmlRpcException: Failed to create input stream: Unexpected end of file from serverat the top of my stack trace followed by a bunch of steps down to: java.net.SocketException: Unexpected end of file from server at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:769) ... So basically, it seems that ws-xmlrpc is convinced that the reply from rTorrent is malformed somehow but other libraries apparently have no problem with it. The code I use to call rTorrent is: private Object callRTorrent(String command, Object[] params) { Object result = null; try { // xmlrpcclient is an XmlRpcClient object and is instantied in // the class constructor result = xmlrpcclient.execute(command, params); } catch(XmlRpcException xre) { System.out.println("Unable to execute method "+command); xre.printStackTrace(); } return result; } With command set to system.listMethodsand params set to an empty Object[]. From reading documentation and googling my conclusion is that I'm not doing anything obviously wrong and this problem doesn't appear to be common, so does anyone have a clue what's going on here?
