  • CakePHP save without form

    - by SDwebs
    I have a photo gallery I'm trying to set a picture as the cover for the album. I have a field cover_id in the albums table that has already been linked to the photos through the model. I'm passing the album_id and photo_id to the controller. I want to update the album.cover_id passed thru the params with the photo_id passed thru the params. Is there a way to do this or a way to make the link a form without having it look like or form or changing much of the CSS?

  • How to overload shutdown function?

    - by Michal M
    I am using Kohana (v3) framework but I believe it's not tied to a particular framework. What I have is basically an app with a front-end, where I want to use Kohana's native Kohana::shutdown_handler(), but I also have a part of the - RESTful API - where I don't want colourful and html-encoded exception reporting. I want a plain text reporting. The way I thought it might work is to register another shutdown function in API's controller abstract class constructor, but then I realised register_shutdown_function() works differently to set_exception_handler() and instead of replacing it adds another function to the shutdown procedure. What's worse PHP doesn't allow "unregistering" shutdown functions and that's where my problem lies. What to do, if you want to use another shutdown function instead of one already registered?

  • Adjusting for compass wrap around in a navigation application

    - by chris12892
    I have a application where I am guiding a vehicle on compass headings and I am having an issue when the vehicle is crossing from 360 degrees to 0 degrees. In this case, there are no smarts in the control loop to compute that the nearest way to turn to follow a heading. For example, if the vehicle is instructed to follow a heading of 360 degrees, it will inevitably drifts a few degrees to ether side. If it drifts over to 0+ degrees, the control loop will go nuts and try to steer the vehicle all the way around to get it to 360 degrees again. Is there a graceful way to deal with this? The way the navigate function is written, I use an external PID controller class and I calculate the heading like this: lock (steering) { if (!Engaged) { return; } double mv = 90 + Trim + pidController.CalculateCorrection(flyHeading, currentHeading); steering.Degree = mv; } Thanks!

  • Grails design for domain class initialization from static data

    - by Allison Eer
    I have some data, stateNames, to instantiate an instance of the object Country. Right now, I will only have one Country but stateNames for each country should be different. What is the best way to instantiate the instance of Country with my data? I am new to grails and would appreciate any "best practices" or common designs. One solution I can think of is to use BootStrap to save the unitedStates instance of Country to the database. What are the cons of this approach? Another solution would be to save the data in a file (in xml?) under web-app folder. If I did this approach, should the unitedStates instance of Country be instantiated by a controller?

  • Urls parameters doesn't encoding correctly!

    - by Ivan90
    I'am using asp.net mvc version 1.0 and I've a problem with some parameter in a url! My url is look like so(http://localhost:2282/Tags/PostList/c#) routes.MapRoute( "TagsRoute", "Tags/PostList/{tag}", new { controller="Tags",Action="PostList",tag = "" } ); In effect the problem is that tag paramter isn't encoding and so simbol # is ignored! I am using an actionlink but maybe with version 1.0 isn't encoding parameter directly! <%=Html.ActionLink(itemtags.Tags.TagName, "PostList","Tags", new { tag = itemtags.Tags.TagName }, new { style = "color:red;" })%> With this actionlink only whitespace are encoding correctly, infact asp.net mvc become asp.net%20mvc and it work fine! But c# isn't encoding :( So I try to use Server.UrlEncode, and in effect it happen some stuff!!! Infact c# became c%2523 but it isn't correct again because hexadecimal of # is %23! Have you some solutions???? Route Contraints? Thanks

  • Ruby on Rails updating join table records

    - by Eef
    Hey, I have two models Users and Roles. I have setup a many to many relationship between the two models and I have a joint table called roles_users. I have a form on a page with a list of roles which the user checks a checkbox and it posts to the controller which then updates the roles_users table. At the moment in my update method I am doing this because I am not sure of a better way: role_ids = params[:role_ids] user.roles.clear role_ids.each do |role| user.roles << Role.find(role) end unless role_ids.nil? So I am clearing all the entries out then looping threw all the role ids sent from the form via post, I also noticed that if all the checkboxes are checked and the form posted it keeps adding duplicate records, could anyone give some advice on a more efficent way of doing this?

  • UIViewController is popped from view stack and NSURLConnection crashes the application

    - by rickharrison
    I am pushing a UIViewController onto a UINavigationController. This view controller immediately starts a download of an xml feed and then parses it. However, if you hit the back button before it is done downloading, and crashes with EXC_BAD_ACCESS. The line that is crashing it is in parserDidEndDocument and is this line: if (self.delegate && [self.delegate conformsToProtocol:@protocol(ModelDelegate)]) [self.delegate modelDidFinishParsing:self]; I assume it is crashing because it is trying to access self.delegate which is not assigned anymore. How do I get around this? Also, I would release the model object in the modelDidFinishParsing method. How would I release this model if it never reaches this method.

  • Recreating iPhone stock application with nested views

    - by john
    I am trying to create an app similar to the Yahoo Stocks app that comes on the iPhone, with the split-screen interface (table on the top, graph on the bottom). I'm struggling with the view hierarchy. What is the easiest way to implement a split-screen type of application. I basically want two views nested in a parent view. My problem is a little bit more complex because I want functionality like having a uipagecontrol (does this require another viewcontroller, or is simply implemented in the initial view controller)? To what degree do I need to use IB? I would prefer to do this all in Xcode. Thanks in advance!

  • hidden form element not bound?

    - by csetzkorn
    Is it standard/intended behaviour that the value of a hidden form field is not bound to the view model (nor is a query string value)? Example: <%= Html.Hidden("test", "13" )%> if my poco view model contains a property test it should be bound shouldn't it?! i have to set it explicitely in the controller at the moment which kind of defeats the objective doesn't it? bla( formviewmodel m, string test) { m.test = test; } any feedback appreciated. thanks! christian

    Hello, I want to create a website where the main pages will be served from CodeIgniter. I will use Wordpress in the /blog/ sub-directory to host the blog. Thats it! I want nothing else. Just to make sure that: example.com/somepage/ calls a CI controller where as example.com/blog/some-post/ is handled by Wordpress. I don't need any kind of integration or interaction between CI and WP. Is it possible to install in that way? If not, any workarounds so that I can achieve the objectives? Thanks and Regards, Masnun

  • NSArrayController that is sorted and unique (no duplicates) for use in a pop-up in a core-data app

    - by Douglas Weaver
    I have core data app with an entity OBSERVATION that has as one of its attributes DEALNAME. I want to reference through Interface Builder or by making custom modifications to an NSArrayController a list of unique sorted dealnames so that I can use them in a pop-up. I have attempted to use @distinctUnionOfSets (and @distinctUnionOfArrays) but am unable to locate the proper key sequence. I can sort the ArrayController by providing a sort descriptor, but do not know how to eliminate duplicates. Are the @distinct... keys the right methodology? It would seem to provide the easiest way to optimize the use of IB. Is there a predicate form for removing duplicates? Or do I need to use my custom controller to extract an NSSet of the specific dealnames, put them back in an array and sort it and reference the custom array from IB? Any help would be appreciated. I am astounded that other have not tried to create a sorted-unique pop-up in tableviews.

  • Pass dynamic value in URL with CakePHP

    - by Renato Dinhani Conceição
    I have the following method that performs an Ajax request passing some dynamic value obtained from a select input. It works fine, but the dynamic value is passed as parameter in the URL, something like states/listCities/?big_string_of_serialized_parameter . $this->Js->event( 'change', $this->Js->request( array( #url 'controller' => 'states', 'action' => 'listCities'), array( # ajax options that generates the serialized parameter 'update' => '#DealerCityId', 'data' => '$("#DealerStateId").serialize()', 'dataExpression' => true ) ) ); I'm trying to do this in a more friendly URL way, something like states/listCities/2. It's possible in CakePHP to generate a friendly URL like this with dynamic value from a input or is only possible passing the dynamic values as parameters?

  • ASP.NET MVC. Hot to guess autogenerated id value ?

    - by Andrew Florko
    My web form contains list of dynamic fields that are generated like this: <% for (int i = 0; i < Model.Options.Count; i++) { %> ... <%= Html.Hidden("Options[" + i + "].Id", Model.Options[i].Id)%> <%= Html.CheckBox("Options[" + i + "].Selected", Model.Options[i].Selected)%> ... This maps perfectly on array of controller method parameters as described in Model Binding To A List article. I want to add label for checkboxes to title them, but I have to guess their ids in hmtl layout. Options[" + i + "].Selected turns into Options_0__Selected How can I avoid hardcoding Id generation in-built asp.net mvc rules? Thank you advance.

  • What is the preferred way of loading browser-specific CSS files?

    - by Yuval A
    What is the best way to handle browser-specific CSS file loading? Assume you are running in the context of a proper MVC framework. Here are some options, you are free to discuss the pros and cons of these options as well as any other methods you know of, and prefer: Server-side solution: use the controller (e.g. servlet) to analyze the user-agent header in the request and return the proper CSS file in the view. Use browser specific hacks to load files, such as: <!--[if IE]> ... <![endif]--> Load CSS files asynchronously in client side by inspecting user-agent and adding respective files Use a client side framework to handle browser-specifics (such as jQuery browser-specific css rules)

    Hi, I have the following problem. I need to export a PDF in a controller The code below, where I return a View, works as expected. @RequestMapping(method = RequestMethod.GET) public View exportReport( @RequestParam(value = "userName", required = true) String userName, @RequestParam(value = "startDate", required = true) Date startDate, @RequestParam(value = "endDate", required = true) Date endDate) { /////////////////////////////////////////// return new TimeSheetReportPdfView(); } The problem occurs if I change the method to return a ModelAndView: @RequestMapping(method = RequestMethod.GET) public ModelAndView exportReport( @RequestParam(value = "userName", required = true) String userName, @RequestParam(value = "startDate", required = true) Date startDate, @RequestParam(value = "endDate", required = true) Date endDate) { /////////////////////////////////////////// return new ModelAndView(new TimeSheetReportPdfView(), model); } Now, the PDF is not exported, all I get is a blank page and nothing in the logs.

  • Updating div after full page refresh following AJAX request

    - by TonE
    Hi, I have an AJAX controller action which returns JSON. The returned JSON is handled via jQuery and contains a message displayed in an update div. The JSON also contains a flag which indicates a change in state. If this is true the entire page needs to be reloaded from a different url. This is currently performed in the jQuery using window.location.replace(url). In the situation where a full page refresh occurs, I still want to display the message from the JSON in the update div, but after the page has fully reloaded. How can I ensure the div is updated with the message after the window.location.replace call and the page has been completely reloaded? Thanks. (I realise AJAX is not intended for full page refreshes but I can't think of a simple way of avoiding it in this scenario. Normal behaviour here is updating the div with a status message.)

  • File listing with ActiveX

    - by Studer
    I need to program a simple Windows Explorer that only lists all files inside a folder recursively. The only solution I found up to now is using an ActiveX controller. So, I installed Visual Studio 2010, but I don't know really how to use it to make an ActiveX. I tried to create a Class Library then add a Explorer module. It compiles, but I don't know what to do now. Is there an easier way to do this or am I missing something ?

    Hello guys ! I'am trying to retrieve an parameter passed in a url using the zend framework. But of course, it is not working ! My code looks like this : Generating the url : <?php echo $this->url(array('controller' => 'poll', 'action' => 'showresults', 'poll_id' => $poll['_id']), null, true) ?> Retrieving the "poll_id" parameter in showresultsAction() : $request = new Zend_Controller_Request_Http(); $poll_id = $request->getParam('poll_id'); The problem is that $poll_id is NULL. When I do a var_dump of $request-getParams(), it is also NULL. I have glanced trough the Zend Framework doc, but it was not very usefull. Any idea ? Thanks !

  • Best practice in Rails when editing scaffold made pages

    - by abegbg
    I have a best practice question. I have two classes, company and category. They have a many-to-many relationship. When clicking a category I shall go to a page showing all companies with the chosen category. Pretty straight forward. My question is: Should I list all the companies on the companies/index.html.erb after filtering the companies in the controller? or Should I list all the companies on the categories/show.html.erb page? or Should I do a completely new page, since it doesn't really fit into any of the two above? Do you generally make a new page when your goal doesn't fit the scaffold made pages or do you use them quite freely? I am working/learning alone with rails, so there are a lot of best practice questions popping up all the time. Cheers Carl
