  • Pass dynamic data to mvc controller with AJAX

    - by Yustme
    How can I pass dynamic data with an AJAX call to an MVC Controller? Controller: public JsonResult ApplyFilters(dynamic filters){ return null; } The AJAX call: $(':checkbox').click(function (event) { var serviceIds = $('input[type="checkbox"]:checked').map(function () { return $(this).val(); }).toArray(); //alert(serviceIds); $.ajax({ type: 'GET', url: '/home/ApplyFilters', data: JSON.stringify({ name: serviceIds }), contentType: 'application/json', success: function (data) { alert("succeeded"); }, error: function (err, data) { alert("Error " + err.responseText); } }); //return false; }); Ideally would be that the filters would contain the serviceIds as a property For example like this: filters.ServiceIds. I got another filter for a date range and that one would be added like so: filters.DateRange. And server side get the filter as a dynamic object in the ApplyFilters()

  • PHP Serialization Will not work correctly.

    - by stevoo
    Hi, I am developing and doing all the testing on a local machine using PHP Version 5.3.3-1ubuntu9.1 version. The host machine is PHP Version 5.2.15. All the seriliaze arguments are identical. The problems is when i try to login the user on my test local machine i do the following : $user->getByUserId($results['id'],$db); $_SESSION['user'] = serialize($user); which retrieved me and serialize the user. and i just load it back when ever i detect that a session exists $user->LoadFromObject(unserialize($_SESSION['user'])); This works perfectly on my test machine. Just transfered the files on the host to see if i can get a beta version out but i keep on getting Warning: unserialize() expects parameter 1 to be string, object given in /home/gamerent/public_html/beta/includes/header.php on line 19 i have noticed that if i echo the $_SESSION['user'] in both system the test will indeed display me the serializated one but the main one will just show me the object and will not serialize the $user

  • Is there a technical way to speed up a general program above current PC speed limit?

    - by Maksee
    Let's imagine I developed a Windows console application implementing some algorithm calculating something. Let's say it doesn't use any threads, just straightforward linear approach with ifs, loops and so on. Is there any technical way to make if run it 100x times faster than on the most advanced current PC? For example one of the way would be to run it on a super computer that emulates i386 faster than any of the existing PCs. But in this case the question what computer and does it really have ability to emulate Windows. In other words, is there real examples of such approach? Although in general it looks useless, but if there is a way, one could develop some program on his general home computer and pay for running it much faster on some other hardware. I suppose that this question could be asked on superuser.com, but since there are possible specific with such things as assembler instructions or threads, I thought that stackoverflow.com is better

  • PHP MVC: How to implement an effective Controller/View Association like ZendFramework guys do!

    - by Navi
    Hi, I am making my own PHP-MVC framework. i have a question regarding Controller and View Association. I love the way Zend framework uses view within Controller as follow: $this->view->data = 'Data here'; so it can be used in view as follow: echo $this->data; I am wondering how can i implement this association. I want to remove codes between /** **/ and want to replace with some magic functions. My codes for controller as as follow: class UserController extends Controller{ /************************************/ public function __construct(){ $this->view = new View(); $this->view->setLayout( 'home' ); } function __destruct(){ $this->view->render(); } /************************************/ public function index(){ $this->redirect('user/login'); } public function login(){ } public function register(){ } public function forgotPassword(){ } } Thanks and best regards, -Navi

  • Other SecurityManager implementations available?

    - by mhaller
    Is there any other implementation (e.g. in an OSS project) of a Java SecurityManager available which has more features than the one in the JDK? I'm looking for features like configurable at runtime policies updateable at runtime, read from other data sources than a security.policy file Thread-aware, e.g. different policies per Thread Higher-level policies, e.g. "Disable network functions, but allow JDBC traffic" Common predefined policies, e.g. "Allow read-access to usual system properties like file.encoding or line.separator, but disallow read-access to user.home" Monitoring and audit trace logging, e.g. "Log all file access, log all network access going NOT to knownhost.example.org" Blocking jobs "requesting" a permission until an administrator grants permission, letting the thread/job continue ... I'm pretty sure that application servers (at least the commercial ones) have their own SecurityManager implementation or at least their own policy configuration. I'm wondering if there is any free project with similar requirements.

  • ListView not showing up in fragment

    - by aindurti
    When I insert a listview in a fragment in my application, it doesn't show up after I populate it with items. In fact, the application crashes due to a NullPointerException. Can anybody help me?

  • Annotation based view mapping

    - by Eqbal
    I am trying to get my head around annotation based mappings and I am having some trouble mapping requests directly to jsp. Do all request have to go through a controller? Is it possible to make it just go to a jsp without declaring a RequestMapping for GET? I am using a InternalResourceViewResolver. Below is my app-servlet.xml <context:annotation-config/> <context:component-scan base-package="com.pioneer.b2broe.web" /> <mvc:annotation-driven /> <mvc:view-controller path="/" view-name="home"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:viewClass="org.springframework.web.servlet.view.JstlView" p:suffix=".jsp" p:order="2"/>

  • Why can't I access a web app running on my Mac via my iPhone?

    - by bpapa
    I'm developing an iPhone app that has a network component. I'm developing the app in Java (Google App Engine actually), running on port 8080. And it works, when I test my app in the iPhone simulator. But now I am trying to test on the device, and I can't hit my Jetty instance. I can certainly access my Mac via the iPhone because I'm able to hit http://10.0.1.7/~brianpapa/ and view my Home Folder when Web Sharing is turned on. But when I try to hit http://10.0.1.7:8080/, it says it can't connect to the server. Interestingly, if I try to hit http://10.0.1.7:8080/ from my mac, it doesn't work either - I have to use localhost as the hostname instead, then it's fine. Has anybody ever encountered this before, and know how to fix it?

  • How to enable absolute paths in LaTeX

    - by Matthias Günther
    Hey, I have one document under ~/my_files/test.tex and want to include in test.tex some styling informations, which can be found under ~/latex/styles/info_hypersetup.tex. When I include the following statement into my test.tex: %% setting the infos for the pdf \include{home/helex/latex/styles/info_hypersetup.tex} I get the following error when running pdflatex test.test: ! I can't write on file `~/latex/styles/info_hypersetup.tex.aux'. I set the rights to 777 but this doesn't changed anything. It works, if I put info_hypersetup.tex in the directory-structure where test.tex is. But I want to use this styleinformation as a global setting for all my documents and don't want to copy it into every project. Thanks for your help.

  • Why first arg to execve() must be path to executable

    - by EBM
    I understand that execve() and family require the first argument of its argument array to be the same as the executable that is also pointed to by its first argument. That is, in this: execve(prog, args, env); args[0] will usually be the same as prog. But I can't seem to find information as to why this is. I also understand that executables (er, at least shell scripts) always have their calling path as the first argument when running, but I would think that the shell would do the work to put it there, and execve() would just call the executable using the path given in its first argument ("prog" from above), then passing the argument array ("args" from above) as one would on the command line.... i.e., I don't call scripts on the command line with a duplicate executable path in the args list.... /bin/ls /bin/ls /home/john Can someone explain?

  • Launching an activity at its current state.

    - by Profete162
    Hello, I am trying to make a task switcher and i succed in it. My only problem is that when I launch activities, they are relaunched as they were new activities ( for instance, I am writing an email, i press home and go into my activity,launch email, and then the app launch the email bout goes back at the inbox and the email is lost) So that's not true multitasking. Here are my steps: 1) getting all the running apps: List<ActivityManager.RunningTaskInfo> allTasks = activityManager.getRunningTasks(30); 2) getting the intent: for (ActivityManager.RunningTaskInfo aTask : allTasks) { Intent i = new Intent(Intent.ACTION_MAIN); i.setComponent(aTask.baseActivity); (...) 3) Launching the application when clicking on the button: intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED).addCategory(Intent.CATEGORY_LAUNCHER); monthis.startActivity(intent); ` What is wrong with this code? Should I do something different to get it? Thank a lot for any answer.

  • bytea type & nulls, Postgres

    - by Thanatos
    I'm using a bytea type in PostgreSQL, which, to my understanding, contains just a series of bytes. However, I can't get it to play well with nulls. For example: =# select length(E'aa\x00aa'::bytea); length -------- 2 (1 row) I was expecting 5. Also: =# select md5(E'aa\x00aa'::bytea); md5 ---------------------------------- 4124bc0a9335c27f086f24ba207a4912 (1 row) That's the MD5 of "aa", not "aa\x00aa". Clearly, I'm Doing It Wrong, but I don't know what I'm doing wrong. I'm also on an older version of Postgres (8.1.11) for reasons outside of my control. (I'll see if this behaves the same on the latest Postgres as soon as I get home...)

    I need to add a span tag to the title of an actionlink to output the following html <li><a href="#" id="topmenu1" accesskey="1" title=""><span>Homepage</span></a></li> I currently have <li><%= Html.ActionLink("Homepage", "Index", "Home", null, new { @id= "topmenu1" , @accesskey = "1", @title = "" } ) %></li> which gives me <li><a accesskey="1" href="/" id="topmenu1" title="">Homepage</a></li> without the span tag around Homepage I cannot use <span>Homepage</span> as the title variable of the actionlink, that doesn't work.

  • is this a secure approach in ActiveRecords in Rails?

    - by Adnan
    Hello, I am using the following for my customers to unsubscribe from my mailing list; def index @user = User.find_by_salt(params[:subscribe_code]) if @user.nil? flash[:notice] = "the link is not valid...." render :action => 'index' else Notification.delete_all(:user_id => @user.id) flash[:notice] = "you have been unsubscribed....." redirect_to :controller => 'home' end end my link looks like; http://site.com/unsubscribe/32hj5h2j33j3h333 so the above compares the random string to a field in my user table and accordingly deletes data from the notification table. My question; is this approach secure? is there a better/more efficient way for doing this? All suggestions are welcome.

  • Unable to output XML data in a manageable way

    - by Rob
    I've been given data from a previous version of a website (it was a custom CMS) and am looking to get it into a state that I can import it into my Wordpress site. This is what I'm working on - http://www.teamworksdesign.com/clients/ciw/datatest/index.php. If you scroll down to row 187 the data starts to fail (there should be a red message) with the following error message: Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /home/teamwork/public_html/clients/ciw/datatest/index.php:132 Stack trace: #0 /home/teamwork/public_html/clients/ciw/datatest/index.php(132): SimpleXMLElement-__construct(' Can anyone see what the problem is and how to fix it?

  • VirtualHost problem with passenger (mod_rails)

    - by Jake
    Hi all, I'm at my wit's end here with virtual hosting. I'm trying to install redmine and it works with the webrick test server, but when I tried to use passenger (mod_rails) to host and go to the address I specified when in the virtualhost part of my apache config file nothing happens. Here is the relavent section of /etc/httpd/conf/httpd.conf where I try to set up the virtual host: <VirtualHost *:80> SetEnv RAILS_ENV production ServerName redmine.MYSITE.com:80 DocumentRoot /opt/redmine-1.0.5/public/ <Directory /opt/redmine-1.0.5/public/> Options -MultiViews Allow from all AllowOverride none </Directory> However, when I got to redmine.MYSITE.com:80 nothing happens, I just get our normal home page. I have no idea what the problem is, any help our guidance would be greatly appreciated. If you need any other information, please tell me and I'll provide it.

  • Python Eggs on Google App Engine

    - by ott
    Usually I would use virtualenv and pip for deployment of web applications. With Google App Engine this doesn't work, because all import statement are relative to directory of the application. The most common approach I saw was to simply copy the packages from site-packages to the directory of the application. This involves manual work and is error-prone. Another approach was to changes install_lib and install_scripts in ~/.pydisutils.cfg, but this doesn't allow me to use pip in my home directory simultaneously. Do you have any suggestions for this?
