  • JQuery: how to store records id for data from ajax query in dynamicly created html elements

    - by grapkulec
    Probably question title is rather cryptic but I will try to explain myself here so please bare with me :) Let's assume this configuration: server-side is PHP application responding for requests with data (list of items, single item details, etc.) in json format client-side is JQuery application sending ajax request to that PHP app and creating html content corresponding with received data So, for example: client requests "list of all animals with names staring with 'A'", gets the json response from server, and for every "animal" creates some html gizmo like div with animal description or something like that. It doesn't really matter what html element it will be but it has to point exactly to specific record by "containing" id of that record. And here is my dilemma: is it good solution to use "id" property for that? So it would be like: <div id="10" class="animal"> <p> This is animal of very mysterious kind... </p> </div> <div id="11" class="animal"> <p> And this one is very common to our country... </p> </div> where id="10" is of course indication that this is representation of record with id = 10. Or maybe I should store this record id in some custom made tag like <record_id>10</record_id> and leave an "id" strictly for what it was meant to be (css selector)? I need that record id for further stuff like updating database with some user input or deleting some of "animals" or creating new ones or anything that will be needed. All manipulations will be done with JQuery and ajax requests and responses will be visualized also with dynamic creation of html interface. I'm sure that somebody had to deal with that kind of stuff before so I would be grateful for some tips on that topic.

  • Precompile assets for a rails engine

    - by Peter Ehrlich
    In a standard app, I have this line in my production.rb, which creates endpoints for non-default precompiled assets: config.assets.precompile += %w( mobile.css ) My rails engine is a standard Sinatra app. It has its own assets. When on development, these assets are served fine, presumably the web requests are handled by rails and sprockets. On production I'm getting 404s on the assets, and think I have to manually tell sprockets to provide the files. How can this be done without tightly linking? It isin't evident how to set up env-specific initializers for engines. Is this done? Not only, for example, is config/development.rb within the engine not loaded, but there's no way to get the application class itself without knowing its name, in order to modify configuration. And even if there was, it seems that having any engine able to reconfigure the main app would be very bad idea. So maybe its better to let assets handling be done by sinatra itself? Or another instance of sprockets for the engine? How do other engines handle this?

  • Run arbitrary subprocesses on Windows and still terminate cleanly?

    - by Weeble
    I have an application A that I would like to be able to invoke arbitrary other processes as specified by a user in a configuration file. Batch script B is one such process a user would like to be invoked by A. B sets up some environment variables, shows some messages and invokes a compiler C to do some work. Does Windows provide a standard way for arbitrary processes to be terminated cleanly? Suppose A is run in a console and receives a CTRL+C. Can it pass this on to B and C? Suppose A runs in a window and the user tries to close the window, can it cancel B and C? TerminateProcess is an option, but not a very good one. If A uses TerminateProcess on B, C keeps running. This could cause nasty problems if C is long-running, since we might start another instance of C to operate on the same files while the first instance of C is still secretly at work. In addition, TerminateProcess doesn't result in a clean exit. GenerateConsoleCtrlEvent sounds nice, and might work when everything's running in a console, but the documentation says that you can only send CTRL+C to your own console, and so wouldn't help if A were running in a window. Is there any equivalent to SIGINT on Windows? I would love to find an article like this one: http://www.cons.org/cracauer/sigint.html for Windows.

  • Why does Rails screw up timezones when I am editing a resource?

    - by DJTripleThreat
    Steps to produce this: prompt>rails test_app prompt>cd test_app prompt>script/generate scaffold date_test my_date:datetime prompt>rake db:migrate now edit your app/views/date_tests/edit.html.erb: <h1>Editing date_test</h1> <% form_for(@date_test) do |f| %> <%= f.error_messages %> <p> RIGHT!<br/> <%= text_field_tag @date_test, f.object.my_date %> </p> <p> WRONG!<br /> <%= f.text_field :my_date %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> <%= link_to 'Show', @date_test %> | <%= link_to 'Back', date_tests_path %> now edit your config/environment.rb: #add this config.time_zone = 'Central Time (US & Canada)' This recreates the problem I am having in my actual app. The problem with my app is that I'm storing a date in a hidden field and rendering a "user friendly" version. Creating a resource works fine but as soon as I try to edit it the time changes (it adds the difference between my current time zone configuration and UTC). go to http://localhost:3000/date_tests/new and save the time then go to reedit it and you will have two different representations of the date/time one which will save incorrectly and the other that will.

  • Dynamic WCF base addresses in SharePoint

    - by Paul Bevis
    I'm attempting to host a WCF service in SharePoint. I have configured the service to be compatible with ASP.NET to allow me access to HttpContext and session information [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)] public class MISDataService : IMISDataService { ... } And my configuration looks like this <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> <services> <service name="MISDataService"> <endpoint address="" binding="webHttpBinding" contract="MISDataViews.IMISDataService" /> </service> </services> </system.serviceModel> Whilst this gives me access to the current HTTP context, the serivce is always hosted under the root domain, i.e. http://www.mydomain.com/_layouts/MISDataService.svc. In SharePoint the URL being accessed gives you specific context information about the current site via the SPContext class. So with the service hosted in a virtual directory, I would like it to be available on mulitple addresses e.g. http://www.mydomain.com/_layouts/MISDataService.svc http://www.mydomain.com/sites/site1/_layouts/MISDataService.svc http://www.mydomain.com/sites/site2/_layouts/MISDataService.svc so that the service can figure out what data to return based upon the current context. Is it possible to configure the endpoint address dynamically? Or is the only alternative to host the service in one location and then pass the "context" to it some how?

  • Unity: Replace registered type with another type at runtime

    - by gehho
    We have a scenario where the user can choose between different hardware at runtime. In the background we have several different hardware classes which all implement an IHardware interface. We would like to use Unity to register the currently selected hardware instance for this interface. However, when the user selects another hardware, this would require us to replace this registration at runtime. The following example might make this clearer: public interface IHardware { // some methods... } public class HardwareA : IHardware { // ... } public class HardwareB : IHardware { // ... } container.RegisterInstance<IHardware>(new HardwareA()); // user selects new hardware somewhere in the configuration... // the following is invalid code, but can it be achieved another way? container.ReplaceInstance<IHardware>(new HardwareB()); Can this behavior be achieved somehow? BTW: I am completely aware that instances which have already been resolved from the container will not be replaced with the new instances, of course. We would take care of that ourselves by forcing them to resolve the instance once again.

  • Apache redirection problem!!!!

    - by vikas
    Hi guys, I am setting up a pre-built website built in php. The site was actually hosted on the linux server. Now I am trying to set it up on a Window machine with WAMP server. In this website almost every page request passes through a particular file called redirect(which is basically a php file without extension). Now the problem is that when I inspected the configuration(httpd.conf, apache.conf,.htaccess, vhost.conf etc) of the apache server on the linux machine, I nowhere found the redirect rules for doing so. Neither mod_rewrite nor mod_alias rules for this redirection were found there. But is still redirects the request properly. I also noticed that Zend Framework library is there in the exact same directory where the redirect file is. This library is included in the include_path in php.ini. However, the web site is still not developed using Zend MVC and I have seen NO proof of ZEND being used there. So I am really confused how this redirection is working there? I am unable to set up this on window machine without rewrite rules of mod_rewrite or mod_alias. Do you guys know any alternative of both the said modules for redirection? I know the site is really weird, but i have to set it up. :) Thanks in advance for your help.

  • How can I build a generic dataset-handling Perl library?

    - by Pep.
    Hello, I want to build a generic Perl module for handling and analysing biomedical character separated datasets and which can, most certain, be used on any kind of datasets that contain a mixture of categorical (A,B,C,..) and continuous (1.2,3,881..) and identifier (XXX1,XXX2...). The plan is to have people initialize the module and then use some arguments to point to the data file(s), the place were the analysis reports should be placed and the structure of the data. By structure of data I mean which variable is in which place and its name/type. And this is where I need some enlightenment. I am baffled how to do this in a clean way. Obviously, having people create a simple schema file, be it XML or some other format would be the cleanest but maybe not all people enjoy doing something like this. The solutions I can think of are: Create a configuration file in XML or similar and with a prespecified format. Pass the information during initialization of the module. Use the first row of the data as headers and try to guess types (ouch) Surely there must be a "canonical" way of doing this that is also usable and efficient. Thanks p.

  • Structuring the UI code of a single-page EXTjs Web app using Rails?

    - by Daniel Beardsley
    I’m in the process of creating a large single-page web-app using ext-js for the UI components with Rails on the backend. I’ve come to good solutions for transferring data using Whorm gem and Rails support of RESTful Resources. What I haven’t come to a conclusion on is how to structure the UI and business logic aspects of the application. I’ve had a look at a few options, including Netzke but haven’t seen anything that I really think fits my needs. How should a web-application that uses ext-js components, layouts, and controls in the browser and Rails on the server best implement UI component re-use, good organization, and maintainability while maintaining a flexible layout design. Specifically I’m looking for best-practice suggestions for structuring the code that creates and configures UI components (many UI config options will be based on user data) Should EXT classes be extended in static JS for often re-used customizations and then instantiated with various configuration options by generated JS within html partials? Should partials create javascript blocks that instantiate EXT components? Should partials call helpers that return ruby hashes for EXT component config which is then dumped to Json? Something else entirely? There are many options and I'd love to hear from people who've been down this road and found some methodology that worked for them.

  • `DesignMode` in subcontrols is not set correctly?

    - by affan
    I have a compound control contains nested controls. The problem i am facing is that control read properties from a global setting class which is static and intern read from setting file. To stop individual control from accessing configuration in design mode i added check in each control. If(!DesignMode){ ... //Initialize properties e.g. prop = AppConfig.GetProperty("prop1"); } The problem is that individual control work fine when open in VS. But when i open top control containing nested control i get error by VS designer. The error is that in a nested control DesignMode=false for some reason. I also created a test app and created a simple control within another control to test if there is a problem with VS but it seem to work correctly for any depth of controls. I dont even know how to debug this. For now i comment out the property initializing code and build it and then open designer and there uncomment it and build it again to run it. Did anyone came across this problem or is there any way to fix it.

  • named type not used for constructor injection

    - by nmarun
    Hi, I have a simple console application where I have the following setup: public interface ILogger { void Log(string message); } class NullLogger : ILogger { private readonly string version; public NullLogger() { version = "1.0"; } public NullLogger(string v) { version = v; } public void Log(string message) { Console.WriteLine("NULL " + version + " : " + message); } } The configuration details are below: <type type="UnityConsole.ILogger, UnityConsole" mapTo="UnityConsole.NullLogger, UnityConsole"> My calling code looks as below: IUnityContainer container = new UnityContainer(); UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity"); section.Containers.Default.Configure(container); ILogger nullLogger = container.Resolve(); nullLogger.Log("hello"); This works fine, but once I give a name to this type something like: <type type="UnityConsole.ILogger, UnityConsole" mapTo="UnityConsole.NullLogger, UnityConsole" name="NullLogger"> The above calling code does not work even if I explicitly register the type using container.RegisterType<ILogger, NullLogger>(); I get the error: {"Resolution of the dependency failed, type = \"UnityConsole.ILogger\", name = \"\".

  • Passing jquery JSON from Codeigniter controller to view

    - by dede
    I've been struggling to make it work, but cannot pass the inserted data from the controler to the view in CI using JSON. The input value from the form is successfully inserted into the database, but cannot make it appear in the view. This is my view file ajax_view.php: <script type="text/javascript" src="<?php echo base_url(); ?>js/jquery-1.4.2.min.js"></script> $(document).ready(function(){ $("#submit").click(function(){ var inp = $('#inp').val(); $.post("ajax/ajax_input", { 'send' : inp }, function(data){ alert(data.input_text); }, "json"); }); }); </script> </head> <body> <form id="form1" method="post" action=""> <label for="inp">Text</label> <input type="text" name="inp" id="inp" /> <label for="submit"></label> <input type="submit" name="submit" id="submit" value="Submit" /> And this is the ajax_input method of the ajax.php controller: <?php // Initializing controller ..... // ............................. //ajax method function ajax_input(){ $var_1 = trim($this->input->post('send')); $array = array('input_text' => $var_1); echo json_encode($array); $this->db->insert('ajax',$array); } Trying to debug it with Firebug, it gives me that data.input_text is empty.

  • Fatal error with Custom Magento Module on one server but not the other

    - by Jack
    Hi, I am creating my own custom module in Magento and during testing on a Litespeed server (PHP v5.2.14) I am getting a Fatal Error: Call to a member function batch() on a non-object in ../../../BatchController.php on line 25 that was not appearing during testing on another linux server and a wamp server (PHP v5.2.11). This one has stumped me. I am guessing it has something to do with the server configuration rather than the code itself. But i am just guessing. I was hoping someone here could tell me. The only real major difference I could see, aside from the php versions and environment, is that the server that the error is on is using the Suhosin Patch. But would that be something that could cause this? The line in question is Mage::getModel('mymodule/mymodel')->batch(); which is enclosed in an IF statement. batch() is a public function located in my model file. If you need more code let me know. Thanks!

  • Two Applications using the same index file with Hibernate Search

    - by Dominik Obermaier
    Hi, I want to know if it is possible to use the same index file for an entity in two applications. Let me be more specific: We have an online Application with a frondend for the users and an application for the backend tasks (= administrator interface). Both are running on the same JBOSS AS. Both Applications are using the same database, so they are using the same entities. Of course the package names are not the same in both applications for the entities. So this is our usecase: A user should be able to search via the frondend. The user is only allowed to see results which are tagged with "visible". This tagging happens in our admin interface, so the index for the frontend should be updated every time an entity is tagged as "visible" in the backend. Of course both applications do have the same index root folder. In my index folder there are 2 index files: de.x.x.admin.model.Product de.x.x.frondend.model.Product How to "merge" this via Hibernate Search Configuration? I just did not get it via the documentation... Thanks for any help!

  • Zend hostname route doesn't match when it has child routes

    - by talisker
    I am implementing an Admin module, which contains the following routes: 'router' => array( 'routes' => array( 'admin' => array( 'type' => 'Zend\Mvc\Router\Http\Hostname', 'options' => array( 'route' => ':subdomain.mydomain.local', 'constraints' => array( 'subdomain' => 'admin', ), 'defaults' => array( 'module' => '__NAMESPACE__', 'controller' => 'Admin\Controller\Index', 'action' => 'index', ), ), 'priority' => 9000, 'may_terminate' => true, 'child_routes' => array( 'users' => array( 'type' => 'Zend\Mvc\Router\Http\Literal', 'options' => array( 'route' => '/users', 'defaults' => array( 'module' => '__NAMESPACE__', 'controller' => 'Admin\Controller\Users', 'action' => 'index', ), ), ), ) ), ), ), And this is the home route configuration: 'home' => array( 'type' => 'Zend\Mvc\Router\Http\Literal', 'options' => array( 'route' => '/', 'defaults' => array( 'controller' => 'Application\Controller\Index', 'action' => 'index', ), ), ), When I try to access to http://admin.mydomain.com, the route match always with the homeroute, but if I remove all the child routes from the admin route, the behavior is correct and a http://admin.mydomain.com matches with the adminroute. Any idea?

  • Getting batch_action functionality in Symfony 1.0

    - by Alex Ciminian
    I'm currently working on a web app written in Symfony. I'm supposed to add an "export to CSV" feature in the backend/administration part of the app for some modules. In the list view, there should be an "Export" button which should provide the user with a csv file of the elements that are displayed (considering filtering criteria). I've created a method in the actions class of the module that takes a comma separated list of ids and generates the CSV, but I'm not really sure how to add the link to it in the view. The problem is that the view doesn't exist anywhere, it's generated on the fly from the data in the generator.yml configuration file. I've posted the relevant part of the file below. I'm new to Symfony, so any help would be appreciated :). Thanks, Alex Update list: display: [id, =name, indemn, _status, _participants, _approved_, created_at] title: Lista actiuni object_actions: _edit: ~ _delete: ~ actions: _create: ~ export_csv: name: Export to CSV action: CSVExport params: id=csvActionSubmit filters: [name, county_id, _status_filter, activity_id] fields: id: name: Nr. crt. ... Thanks to your advice, I've managed to add a button that is linked to my action. The problem is that I also need to send some parameters to the action, because I may not want all the elements - filters may have been used. Unfortunately, the project is using Symfony 1.0, which doesn't support batch_actions. Currently, I'm working around this with Javascript (I parse the DOM to get the numeric ids (from the display table) and then build the link for the button. I really think there could be a better way for this.

  • Host WCF in MVC2 Site

    - by Basiclife
    Hi, We've got a very large, complex MVC2 website. We want to add an API for some internal tools and decided to use WCF. Ideally, we want MVC itself to host the WCF service. Reasons include: Although there's multiple tiers to the application, some functionality we'd like in the API requires the website itself (e.g. formatting emails). We use TFS to auto-build (continuous integration) and deploy - The less we need to modify the build and release mechanism the better We use the Unity container and Inversion of Control throughout the application. Being part of the Website would allow us to re-use configuration classes and other helper methods. I've written a custom ServiceBehavior which in turn has a custom InstanceProvider - This allows me to instantiate and configure a container which is then used to service all requests for class instances from WCF. So my question is; Is it possible to host a WCF service from within MVC itself? I've only had experience in Services / Standard Asp.Net websites before and didn't realise MVC2 might be different until I actually tried to wire it into the config and nothing happened. After some googling, there don't seem to be many references to doing this - so thought I'd ask here.

  • How to find which file is open in eclipse editor without using IEditorPart?

    - by Destructor
    I want to know which file (or even project is enough) is opened in eclipse editor? I know we can do this once we get IEditorPart from doSetInput method, IFile file = ((IFileEditorInput) iEditorPart).getFile(); But I want the name of file without using IEditorPart, how can I do the same? Checking which is the selected file in project explorer is not of much help because, user can select multiple files at once and open all simultaneously and I did not way to distinguish which file opened at what time. Adding more info: I have an editor specified for a particular type of file, now every time it opens, during intializing editor I have some operation to do based on project properties. While initializing editor, I need the file handle (of the one which user opened/double clicked) or the corresponding project handle. I have my editor something this way: public class MyEditor extends TextEditor{ @Override protected void initializeEditor() { setSourceViewerConfiguration(new MySourceViewerConfiguration( CDTUITools.getColorManager(), store, "MyPartitions", this)); } //other required methods @Override protected void doSetInput(IEditorInput input) throws CoreException { if(input instanceof IFileEditorInput) { IFile file = ((IFileEditorInput) input).getFile(); } } } as I have done in the doSetInput() method , I want the file handle(even project handle is sufficient). But the problem is in initializeEditor() function there is no reference to editorInput, hence I am unable to get the file handle. In the source viewer configuration file, I set the code scanners and this needs some project specific information that will set the corresponding rules.

  • Compiling Wanderlust for Windows and use it for Gmail.

    - by User1
    I'm trying to get Wanderlust working in Windows to connect to Gmail. Compiling the code is much more painful than expected. Here are the barriers so far: Can't download dependent packages: SEMI, APEL, and FLIM. I eventually found newer versions, but I'm not sure they will work. Anyone have the older versions? Needs make and install. I used MSYS and it seems to have compiled okay. SSL support. I was getting a "Cannot open load file: ssl" error. I found an ssl.el that comes with w3. So installed w3. Bash command in ssl.el: ssl-get-command is running something from /bin/sh (not a directory I have in Windows). I really don't want to refactor this code. Is there a better way? Others speak very highly of Wanderlust, so I want to give it a try. I feel like I'm almost there, but am pretty much worn out with all the crazy configuration I have to do. Does anyone have this working on Windows? I'm pretty sure it will work with Gmail, because of this post. But will it work in Windows too? If you have a few pointers, please help.

  • Should we retire the term "Context"?

    - by MrGumbe
    I'm not sure if there is a more abused term in the world of programming than "Context." A word that has a very clear meaning in the English language has somehow morphed into a hot mess in software development, where the definition where the connotation can be completely different based on what library you happen to be developing in. Tomcat uses the word context to mean the configuration of a web application. Java applets, on the other hand, use an AppletContext to define attributes of the browser and HTML tag that launched it, but the BeanContext is defined as a container. ASP.NET uses the HttpContext object as a grab bag of state - containing information about the current request / response, session, user, server, and application objects. Context Oriented Programming defines the term as "Any information which is computationally accessible may form part of the context upon which behavioral variations depend," which I translate as "anything in the world." The innards of the Windows OS uses the CONTEXT structure to define properties about the hardware environment. The .NET installation classes, however, use the InstallContext property to represent the command line arguments entered to the installation class. The above doesn't even touch how all of us non-framework developers have used the term. I've seen plenty of developers fall into the subconscious trap of "I can't think of anything else to call this class, so I'll name it 'WidgetContext.'" Do you all agree that before naming our class a "Context," we may want to first consider some more descriptive terms? "Environment", "Configuraton", and "ExecutionState" come readily to mind.

My first thought was to check if the list contained zero items, however this is not acceptable because there are times I want to have zero items in the list. In essence I want a file that has been serialized with an older version of the same class to be "upgraded" and have defaults automatically inserted for new properties. How can I do this? For a more visual example of what I'm trying to do, see below: When I deserialize an XML file that contains: <Item1>wtfe</Item1> <Item2>wtfe</Item2> and after I've added a list property it will serialze as: <Item1>wtfe</Item1> <Item2>wtfe</Item2> <Item3/> I want it to serialize as: <Item1>wtfe</Item1> <Item2>wtfe</Item2> <Item3> <DefaultSubItem/ Field="wtfe"> <DefaultSubItem/ Field="wtfe"> </Item3> But allow me to change it to: <Item1>wtfe</Item1> <Item2>wtfe</Item2> <Item3></Item3>

  • What's best choice career-wise, to know a little about a lot or a lot about a little?

    - by nimo
    I work as a developer at a rather small company and we are providing a web application that is used by a big base of customers. Because we are so small everyone have to be able to do a lot of different tasks. It ranges from advanced support, developing the product (programming: c/c++, c#, php, sql, javascript, html, css), handle network configuration and network related issues and even sometimes go on sales meetings with potential customers. My concern is that I don't really specialize in any specific area. I know and learn little about a lot. I have graduated from school two years ago and this is my first real employment and when I look at other positions out there they always require so and so many years of experience in a specific area (for example 5 years of C#). For me to get that kind of specialized experience will be really hard at my current job. My question for you is what is, in your opinion, best choice career-wise, to know a little about a lot or a lot about a little? What path did you take? pros and cons that comes with that choice.
