  • render json data returned from mvc controller

    - by user1765862
    I'm having js function which calls mvc controller action method which return list of data as json. function FillCountryCities(countryId) { $.ajax({ type: 'GET', url: '/User/FillCityCombo', data: { countryId: countryId }, contentType: 'application/json', success: function (data) { alert(data[0].Name); } error: function () { alert('something bad happened'); } .... format of data which sent back from controller is Name (string) and Id (Guid) Now I just want to alert Name on success first item from collection. Double checked controller sends 20 records, so it should alert first from collection but I'm getting error something bad happened update: public JsonResult FillCityCombo(Guid countryId) { var cities = repository.GetData() .Where(x = x.Country.Id == countryId).ToList(); if (Request.IsAjaxRequest()) { return new JsonResult { Data = cities, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } else { return new JsonResult { Data = "Not Valid Request", JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } }

  • Django: do I need to do HttpResponseRedirect to render a simple string after a POST?

    - by AP257
    I've got a mobile app that makes POST requests to a Django site. I want to return a simple string (not a template-based page) after the app makes the POST request, saying 'Success' or 'Failure' as appropriate. However I know that after a POST request in Django you're supposed to do a HttpResponseRedirect. But, do I really need to redirect to another page and write a new function to handle it, all to output a string? And if so, how do I pass the success/failure status of the app in the HttpResponseRedirect, since it's only supposed to take one argument? Thanks!

  • help with Zend dispatcher

    - by simple
    this is the Zend Controller Dispatcher Standart public function isDispatchable(Zend_Controller_Request_Abstract $request) { $className = $this->getControllerClass($request); echo 'is dispatchanble started'; var_dump($className); if (!$className) { return false; } var_dump(class_exists($className, false)); if (class_exists($className, false)) { return true; } $fileSpec = $this->classToFilename($className); $dispatchDir = $this->getDispatchDirectory(); $test = $dispatchDir . DIRECTORY_SEPARATOR . $fileSpec; return Zend_Loader::isReadable($test); } I need to set up custom modular structure and loading just using plugins (I need to setup the path where zend looks for controller), so I am stuck tracing down I came to the isDispatchable method that returns false and consequently the dispatching returns error . This method returns false because class_exists return false , it is surely has to do with auto loading ,but confused. help will be appreciated,though I got the feeling that I am looking at wrong place.

  • Designing server communications like DNS

    - by fryme
    I'm just need some help about server design. I need help in the design of the structure of the server application. Need to develop a network of servers that interact with each other. If a server receives a request and the server can not comply it, then the request is sent to another server and the result will be refunded to the sender. Information on all servers is different, and sender did not know where the result is placed in. The first thing that comes to mind is to use the model(scheme) of the DNS. But any interesting detailed articles on this subject I have not found. Any ideas?

  • Modern way to validate POST-data in MVC 2

    - by zerkms
    There are a lot of articles devoted to working with data in MVC, and nothing about MVC 2. So my question is: what is the proper way to handle POST-query and validate it. Assume we have 2 actions. Both of them operates over the same entity, but each action has it's own separated set of object properties that should be bound in automatic manner. For example: Action "A" should bind only "Name" property of object, taken from POST-request Action "B" should bind only "Date" property of object, taken from POST-request As far as I understand - we cannot use Bind attribute in this case. So - what are the best practices in MVC2 to handle POST-data and probably validate it.

  • How to create a web framework in C# without ASP?

    - by Mark
    I've managed to get a C# asp page running under ubuntu/apache/mono, but I don't want to write my framework in these ASP pages, I want to use straight C# and then I'll use a templating language for my views. But I don't know where to begin? C# is a compiled language, so... how would I do this? Would I compile everything and then have apache hook into the (single) executable and pass in the the request URL? Could I request specific .cs pages and then have apache tell it to compile and then "display" it only if it's been updated? Can the "view" files be compiled individually to avoid having to recompile everything every time there's a change? Is there some "base" I can work from, or am I going to have to reinvent accessing GET and POST variables (by reading header info) and all sorts of other stuff we take for granted in languages like PHP?

  • How can I view the all inherited url-resolution rules affecting a given directory?

    - by john.designop.us
    I work on two sites hosted on the same server, using the same CMS configurations and identical .htaccess files in their respective document roots. One site is letting me use the CMS's clean-url mode, and the other isn't. Site #2 functions fine in ?=messy-url mode, but when I turn clean urls on in the admin panel, and request a rewritten URL, I get a 404 error served before the CMS sees the request. I've contacted the server administrator, but he isn't inclined to provide support and the site owners are beholden to this hosting provider. I have shell access to the Linux-based server, and I can verify that mod_php and mod_rewrite are active, but I don't know what more I can do to troubleshoot this issue. Is there any way to identify directives upstream that may be differentiating the way http requests are handled by the two sites? Thanks!

  • how can JIRA soap API not have this method?

    - by oo
    I want to be able to get a list of issues given a: Project Name and Release Version this seems like a basic JIRA soap API 101 request It seems, looking at the documentation: http://docs.atlassian.com/software/jira/docs/api/rpc-jira-plugin/latest/index.html?com/atlassian/jira/rpc/soap/JiraSoapService.html you can get issues by: Filter SearchTerms SearchTerms and Project but not the above. Is this a complete oversight or i am missing something i would expect to see something like this: RemoteIssue[] issues = _soapService.getIssues(string project_, string version_) any help? UPDATE: I see that JIRA 4.0 is out but i can't find any documentation if the API has changed to support this request above. Can anyone find this link to answer that questions.

  • asp.net mvc 2 multithread

    - by Chris Cap
    I'm getting some weird behavior in asp.net MVC2 (at least it's not what I'm expecting). I have a controller httppost action that processes credit cards. I'm setting a session variable on the server to let me know if a user has attempted to process a card. I clear that session variable when I'm done. I am doing some very quick posts to test the process and the session variable is coming back null everytime because I clear the session variable at the end of the process. I have some debug prints that show me that the all requests are processed synchronously. That is...the first attempt occurs, it fails, session variable is cleared, second attempt tries and fails and the variable is cleared, etc... My first thought was that this was a side effect of debugging and that it just lined requests up for debugging purposes using the local webserver. So I put it on a development server and the same thing is occurring. Multiple submits/posts are processed synchronously. I even put a System.Threading.Sleep in there to make sure it would stop right after I set the session variable and it still won't even START the second request until the first is done. Has anyone else seen this behavior? My understanding was that a worker process was spawned for each request and that these actions could happen asychronously. Here's some psuedo code if (Session["CardCharged"] != null) return RedirectToAction("Index", "Problem"); Session["CardCharged"] = false; //starting the process System.Threading.Thread.Sleep(10000); //charge card here if (!providerResponse.IsApproved) { System.Diagnostics.Debug.WriteLine("failed"); Session["CardCharged"] = null; //have to allow them to charge again since this failed return View(myModel); } Session["CardCharged"] = true; return RedirectToAction("Index", "OrderComplete"); I should mention that my code ALWAYS fails the credit card check for testing purposes. I'm trying to test the situation where processing is STILL occurring and redirect the user elsewhere. I have set a dummy session variable elsewhere to assure that the session id "sticks". So I know the session id is the same for each request. Thanks

  • Hit external url from code-behind

    - by Steven
    I have a form on my site. The user enters their e-mail and selects a location from a dropdown. I then need to post that data to an external site by hitting a url with the user's location and e-mail in the query string. I'm doing this like so: string url = "http://www.site.com/page.aspx?location=" + location.Text + "&email=" + email.Text; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); My client says that I am not hitting their server, but when going through the debugger, I'm getting a response from their server. I also tried tracking what was happening by using Firebug, and I noticed that there was no POST made to that external site. What am I doing wrong here?

  • django - change content inside an iframe

    - by fabriciols
    Hello guys, I have a site running in django and want to make it available on third party sites. In these sites they make my content available through an tag. When my site is requested from within that iframe I would like to modify the content (remove header, filter data, etc.). What would be the best way to do this? Is there any way of knowing that the request is being made from an iframe? Multiples sites will request the same url, can I change the content, based on the requesting site? Thanks! PS: Sorry for my bad english :/

  • Rails 2.3.5: flash[:notice] disappears after redirect_to call

    - by xyzman
    Here I've got two controller methods: def invite if request.post? begin email = AccountMailer.create_invite(@user,url) AccountMailer.deliver(email) flash[:notice] = "Invitation email sent to #{@user.email}" rescue #mail delivery failed flash[:error] = "Failed to deliver invitation" end redirect_to :action => :show, :id => @user.id end end and def show @title = "User #{@user.full_name}" end The problem is, when I send an invitation, and get redirected to ./show, I see no messages at all. If I change redirect_to to render, the message appears. Still, isn't it intended for flash to work in the immediate subsequent requests? BTW, I'm using Rails+Passenger setup, could it be so that redirected request goes to another application instance?

  • PHP cURL: get headers only from post

    - by Stewart
    There ought to be a way of sending a post request and getting back just the headers. $ch = curl_init('http://www.stackoverflow.com/'); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_NOBODY, true); doesn't work, because all setting CURLOPT_NOBODY does is to change the request method to HEAD, thereby overriding CURLOPT_POST. I could just leave the last of these lines out and only process the headers, but is there a more efficient way? It's also odd that there doesn't seem to be a way in cURL to truncate the received content to a specified length as there is with file_get_contents.

  • Is JSONRequest a global Javascript object ?

    - by Anth0
    My goal is to asynchronously call a URL via POST request (REST Webservice) to increment a statistic on one of my object. I am a newby web developper and I discovered JSON yesterday. Since JSON seems a lot popular and handy I went to www.json.org and discovered a JSONRequest object which seems to able one to send POST/GET request asynchronously but I can't get it work. Is it a global Javascript object or do I need to add some files ? I am a little bit confused since I've found a Firefox plugin extension for JSONRequest but I don't understand its purpose.

  • JPA @version - can it be used to calcualate version of a table entry

    - by OpenSource
    Hi, Please consider the following table (created using a corresponding entity) request ------- id requestor type version items 1 a t1 1 5 2 a t1 2 3 3 b t1 1 2 4 a t2 1 4 5 a t1 3 9 The above is what I want to achieve. The version field is a calculated field others are user provided. Basically the request's version needs to be calculated based on the combination of requestor and the type. The first occurance with a given combination will have a version 1 then version 2 and so on. I tried various things using @version on a different entity with just the three columns and joining the two entities using ManytoOne etc but I'm not able to get to the desired outcome. I dont want to confuse you with the things I tried. Since the objective is simple there should be an easier way I suppose? Can you please help? - any help greatly appreciated! thanks in advance

  • What exactly is Appdomain recycling

    - by kudlur
    Hi, I am trying to figure out what exactly is Appdomain recycling? When a aspx page is requested for the first time from a DotNet application, i understand that an appdomain for that app is created, and required assemblies are loaded into that appdomain, and the request will be served. Now, if the web.config file or the contents of the bin folder, etc are modified, the appdomain will be "recycled". My question is, at the end of the recycling process, will the appdomain be loaded with assemblies and ready to serve the next request? or a page has to be requested to trigger the assemblies to load?.

  • Viewstate seems to be hijacked inadvertently

    - by dvr
    Hi, we are using asp.net 2.x, we use session state stored in sql server, 2 web servers in loadbalance, iis6. our issue is that in the last 3 months we have had 2 cases where some one using our enquiry form has seen someone else's info e.g. first name and last name. We are not populating the form from objects in session so I have come to the conclusion that the second user has somehow received the viewstate from the first user, after that user has tried to submit and got an error e.g. has posted view state and returned the the same page and the other user has requested that page at the same time (must have been on the same server I am guessing if it is a viewstate issue). have any of you experienced this before? some questions mulling around in my head is how does the worker process know to retun view state to a unique request and how does it determine a unique request etc..

  • How should nested components interact with model in a GUI application?

    - by fig-gnuton
    Broad design/architecture question. If you have nested components in a GUI, what's the most common way for those components to interact with data? For example, let's say a component receives a click on one of its buttons to save data. Should the save request be delegated up that component's ancestors, with the uppermost ancestor ultimately passing the request to a controller? Or are models/datastores in a GUI application typically singletons, so that a component at any level of a hierarchy can directly get/set data? Or is a controller injected as a dependency down the hierarchy of components, so that any given component is only one intermediary away from the datastore/model?

  • Flex Application for PlayBook Text Input Variable

    - by user568128
    I know this is probably a very simple question, but can someone please walk me through how to take what a user inputs into a s:TextInput and use that as a variable in a JSON data request? Basically, I want to have a user enter a search term, like "math" and then have that placed into a variable so I can use it in a JSON request. Something like public var q:String, except that my search box (and hence user input) is on another "view" of the application. I've just started with Flex Mobile applications and I might be way out of my league. Does anyone know how to do this?

  • securing a webservice for use from a custom iphone app only

    - by mme
    I want to create an iphone application which consists of two parts: The app itself and a server side component. On a users request, the app sends data to the server which is to be handled by human operators. To prevent abuse from an iphone app user, the id of the iphone is sent along with the request, and the operators can blacklist pranksters to deny their iphone access to the service. So far so good. Now the problem is: Someone could easily discover the address of the serverside component, and write a script to send bogus requests, using multiple IP addresses etc. So my question is: how can I defend myself against this? Captchas to protect against scripted attacks or requiring the user to register himself are not an option for this particular application. If I had control of the download, I would associate a unique ID with each downloaded app, but obviously this is not an option with the appstore. What would be your approach to make the server side part more secure?

  • Checking if the email had been already taken in the following if statement (Rails)?

    - by alexchenco
    I have the following action: users.rb: def omniauth_create auth = request.env["omniauth.auth"] user = User.from_omniauth(env["omniauth.auth"]) unless user.email.blank? if user.id.nil? # Save the user since he hasn't been created yet user.save! end sign_in user redirect_back_or user else # Send user to a form to fill his email #session[:omniauth] = request.env['omniauth.auth'].except('extra') redirect_to(enter_email_path(oprovider: user.provider, ouid: user.uid, oname: user.name, opassword: user.password, opassword_confirmation: user.password)) end end It does the following: If the user's email is not blank, sign him in, and redirect him to his profile (and save him if his id is nil. In other words, if he hasn't been created yet). If the user's email is blank, send him to enter_email_path (where the user can enter his email). Now I want to add another if statement that flashes an error if the email had been already taken, and redirects the user to the root_path I'm not very sure how to do this, Any suggestions? (and where to put that if statement?)
