  • [super init] and loading NIB / XIB files?

    - by fuzzygoat
    I am a little curious, I have a view controller class and an NIB/XIB (both are named "MapViewController") If I do the following it loads the NIB with the matching name. -(id)init { self = [super initWithNibName:@"MapViewController" bundle:nil]; if(self) { do things ... } return self; } if on the other hand I just specify [super init] does Xcode just look for a NIB that matches the name of the controller, is that how this is working? -(id)init { self = [super init]; if(self) { do things ... } return self; } cheers Gary.

  • MVC Pages that require the user to be logged in

    - by keithjgrant
    I'm working on a little MVC framework and I'm wondering what the "best way" is to structure things so secure pages/controllers always ensure the user is logged in (and thus automatically redirects to a login page--or elsewhere--if not). Obviously, there are a lot of ways to do it, but I'm wondering what solution(s) are the most common or are considered the best practice. Some ideas I had: Explicitly call user->isLoggedIn() at the beginning of your controller action method? (Seems far too easy to forget and leave an important page unsecure on accident) Make your controller extend a secureController that always checks for login in the constructor? Do this check in the model when secure information is requested? (Seems like redundant calls would be made) Something else entirely? Note: I'm working in PHP, though the question is not language-dependent.

  • How can I fix Grails error: "No domain class found for name PrivacyOptions. Please try again and e

    - by ?????
    I'm just getting started with Groovy/Grails. I added a new domain controller to my project, and generate-controller doesn't like it. There are other indications something's wrong: If I run the app no table is actually created in the database for this. I've reduced the DomainController to one String field and no constraints, just to make sure there wasn't something wrong with my specification. I also tried renaming it, just in case there was something about the original name (Privacy) that conflicted with something. I'm sure I have the correct name, and that the file is called PrivacyOptions.groovy and inside the class is also called PrivacyOptions. Here's the error: Running script /opt/local/grails/scripts/GenerateController.groovy Environment set to development Domain class not found in grails-app/domain, trying hibernate mapped classes... No domain class found for name PrivacyOptions. Please try again and enter a valid domain class name

  • 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.

  • Symfony2 same form, different entities NOT related

    - by user1381537
    I'm trying to write one form for submitting against MySQL DB, but I can't get it working, I've tried a lot of things (separate forms, create an ->add('foo', new foo()) to a field, and trying to parse plain SQL with a normal HTML form is my only solution, which is obviously not the best. This is my DB structure: As you can see I need to insert the comments textarea to ticketcomments among the user who wrote it, etc. On crmentity the description field. Then on ticketcf the fields that I need to submit from form, are this (because you wont know if I don't tell you because of the field names): tcf.cf594 AS Type, tcf.cf675 AS Suscription, tcf.cf770 AS ID_PRODUCT, tcf.cf746 AS NotificationDate, tcf.cf747 AS ResponseDate, tcf.cf748 AS ResolutionDate, And, of course, every table needs to have the same ticketid id for the submitted form, so we can retrieve it with one simple query. It will be easy to do with plain SQL instead of using DQL and Symfony2 forms, but is not a good way to do it. Also, here's my "Ticket list" query, if you need it to have it more clear... SELECT t.ticketNo AS Ticket, t.title AS Asunto, t.status AS Estado, t.updateLog AS LOG, t.hours AS Horas, t.solution AS Solucion, t.priority AS Prioridad, tcf.cf594 AS Tipo, tcf.cf675 AS Suscripcion, tcf.cf770 AS IDPROD, tcf.cf746 AS F_Noti, tcf.cf747 AS F_Resp, tcf.cf748 AS F_Reso, CONCAT (cd.firstname, cd.lastname) AS Contacto, crm.description AS Descripcion, crm.crmid AS id FROM WbsGoclientsBundle:VtigerTroubletickets t INNER JOIN WbsGoclientsBundle:VtigerTicketcf tcf WITH t.ticketid = tcf.ticketid INNER JOIN WbsGoclientsBundle:VtigerContactdetails cd WITH t.parentId = cd.contactid INNER JOIN WbsGoclientsBundle:VtigerCrmentity crm WITH t.ticketid = crm.crmid WHERE t.parentId IN ( SELECT cd1.contactid FROM WbsGoclientsBundle:VtigerContactdetails cd1 WHERE cd1.accountid = ( SELECT cd2.accountid FROM WbsGoclientsBundle:VtigerContactdetails cd2 WHERE cd2.contactid = :contactid)) AND t.status <> \'Closed\' And also "Ticket details" query (which is not in DQL format yet, only SQL) is so simple, it only retrieve the comments field and createdtime from ticketcomments appended to this query so we have all the fields... Thank you. This is a test form, using troubletickets and ticketcomments, it's returning errores because I can't set a comments field because troubletickets doesn't has it, but I need that field to be submitted to ticketcomments ...

EDIT 2 This code is actually rendering my forms, but I need help in order to submit each XXXType form to its corresponding table. public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('descripcion') ->add('prioridad') ->add('solucion') ->add('comment', new VtigerTicketcommentsType() ) ->add('contacto') ->add('suscripcion') ->add('producto', 'entity', array( 'class' => 'WbsGo\clientsBundle\Entity\VtigerAssets', 'property' => 'assetname', 'empty_value' => '--SELECT--', 'query_builder' => function(\WbsGo\clientsBundle\Entity\VtigerAssetsRepository $repository) { //return $repository->findAssetByAccountId($this->customerId); return $repository->createQueryBuilder('a') ->select('a') ->where('a.account = (SELECT cd.accountid FROM WbsGoclientsBundle:VtigerContactdetails cd WHERE cd.contactid = ?1)') ->setParameter(1, $this->customerId); } ) ) ->add('hardware') ->add('backup') ->add('web') ->add('restore') ->add('customerId') ; } I also removed ->add('ticketid') from VtigerTicketcommentsType.php because it has relationship and is not needed. it's auto_incremental and must be generated once everything is submitted.

  • How to show specific link to user that's signed in and on specific page in rails?

    I have the following code for part of my navigation: <% if user_signed_in? %> <li><%= link_to 'Edit Profile', edit_profile_path(current_user.profile) %></li> <li><%= link_to 'Edit Account', edit_user_registration_path %></li> <% elsif user_signed_in? and params[:controller] == 'profiles#edit' %> <li><%= link_to 'View Profile', profile_path(current_user.profile) %></li> <li><%= link_to 'Edit Account', edit_user_registration_path %></li> <% else %> <li><%= link_to 'Sign up', new_user_registration_path %></li> <% end %> I want different links to show depending on where the "user_signed_in" is.

  • will_paginate route only works on page > 1

    I have the following routes defined: map.resources :categories, :has_many => :downloads map.resources :downloads, :member => {:go => :get}, :collection => {:tag => :get} map.connect '/downlods/page/:page', :controller => 'downloads', :action => 'index' map.connect '/categories/:category_id/downloads/page/:page', :controller => 'downloads', :action => 'index' For some reason, the first page that the will_paginate helper is called on causes links with ?page=2 to be rendered, while subsequent pages have links with /downloads/page/2. Do you know what might be causing this?

  • Error handling with Python + Pylons

    - by ensnare
    What is the proper way to handle errors with Python + Pylons? Say a user sets a password via a form that, when passed to a model class via the controller, throws an error because it's too short. How should that error be handled so that an error message gets displayed on the web page rather than the entire script terminating to an error page? Should there be any error handling in the controller itself? I hope I am explaining myself clearly. Thank you.

  • Can someone explain Kohana 3's routing system?

    - by alex
    In bootstrap.php, where you set routes, I'm having a hard time getting them to work. I read some documentation a while ago that I can't seem to find again that explains them. Here is one of my examples Route::set('products', 'products/(type)', array('type' => '.+')) ->defaults(array( 'controller' => 'articles', 'action' => 'view_product', 'page' => 'shock-absorbers', )); I thought that would mean a request like products/something would load up the articles controller, and the action_view_product method. But I can't get it to work. Can someone please explain to me exactly how they work, and what all the method parameters are?

  • How to program a Sort feature

    - by Brian Roisentul
    I'm working on Ruby on rails 2.3.4 and I'm trying to develop a Sort feature on my website's search page(its url is /anuncios/buscar). What I tried is to create a "map" on routes file: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' Then, I wrote this on the view: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance(@announcements) %> And finally, I created a method in the controller, as is specified on the routes' line: def search_filer_relevance raise params.inspect end First of all, as I'm sorting search results, I'd like to keep them in their public variable called @announcements. Please help me do this. An the other thing is that when I click the link I get an error due its trying to access the Show action instead of search_filter_relevance as specified in routes. Why is this happening?

  • IPhone: Controllers, Delagates, DataSources, etc all in one class?

    - by MLS
    Hi All, I am learning iPhone programming. I am starting with a simple example of displaying recently used documents in a UITableView. What I am confused about is why do I need to have several classes and why cant I just use one? Example, My class is called RecentFileList. I need to implement controller, delegate and datasource as well as the actual table view. Can't I just do this all in my RecentFileList Class versus having to create a RecentFileListDelegate RecentFileListController, RecentFileListDataSource class, etc, etc. Related to this can one define a class like: @interface FileListView : NSObject <UITableViewDelegate> <UITableViewController> <UITableViewDataSource { // code } @end or would I just do the work to make my class a delegate and controller in init()?

  • What is the best way to log errors in Zend Framework in my project at this stage?

    - by Pasta
    We built an app in Zend Framework and have not worked a lot in setting up error reporting and logging. Is there any way we could get some level or error reporting without too much change in the code? Is there a ErrorHandler plugin available? The basic requirement is to log errors that happens within the controller, missing controllers, malformed URLs, etc. I also want to be able to log errors within my controllers. Will using error controller here, help me identify and log errors within my controllers? How best to do this with minimal changes?

  • MVC: Structuring Feed Output

    The framework I'm using on my project follows the MVC Pattern. I"M building JSON feeds and need to structure them in a different way then what the system gives me by default from the ORM. Where should I be handling the task of mangling and shaping my data that I'll serve up, in the model, view or controller? Right now I'm doing it in my controller, then passing that data to the view. I can see this fitting better under the Model or the View but not sure which one.

  • 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?

  • More swing design & actions

    - by takoi
    Im pretty new to gui programming so i've been reading through every post on this site about swing and design. Whats been answered over and over again is that one should have a class which handles all the action. Like this: (GUI being some JFrame) Now, this works great for one-way actions, like OpenDialog. But the actions for buttons in DialogA and B will have to have access to all the components (there will be many) in its dialog, and the controller. This is where im stuck. The only sane way i can see is to put it in DialogA/B but i would then need to pass the controller all the way down, through classes that dont even need it, and it'll get all spaghetti. Really dont want that. Someone must have encountered this problem before. So where should i put this Action? Or should i just drop the whole design?

  • Handling Model Inheritance in ASP.NET MVC2

    - by enth
    I've gotten myself stuck on how to handle inheritance in my model when it comes to my controllers/views. Basic Model: public class Procedure : Entity { public Procedure() { } public int Id { get; set; } public DateTime ProcedureDate { get; set; } public ProcedureType Type { get; set; } } public ProcedureA : Procedure { public double VariableA { get; set; } public int VariableB { get; set; } public int Total { get; set; } } public ProcedureB : Procedure { public int Score { get; set; } } etc... many of different procedures eventually. So, I do things like list all the procedures: public class ProcedureController : Controller { public virtual ActionResult List() { IEnumerable<Procedure> procedures = _repository.GetAll(); return View(procedures); } } but now I'm kinda stuck. Basically, from the list page, I need to link to pages where the specific subclass details can be viewed/edited and I'm not sure what the best strategy is. I thought I could add an action on the ProcedureController that would conjure up the right subclass by dynamically figuring out what repository to use and loading the subclass to pass to the view. I had to store the class in the ProcedureType object. I had to create/implement a non-generic IRepository since I can't dynamically cast to a generic one. public virtual ActionResult Details(int procedureID) { Procedure procedure = _repository.GetById(procedureID, false); string className = procedure.Type.Class; Type type = Type.GetType(className, true); Type repositoryType = typeof (IRepository<>).MakeGenericType(type); var repository = (IRepository)DependencyRegistrar.Resolve(repositoryType); Entity procedure = repository.GetById(procedureID, false); return View(procedure); } I haven't even started sorting out how the view is going to determine which partial to load to display the subclass details. I'm wondering if this is a good approach? This makes determining the URL easy. It makes reusing the Procedure display code easy. Another approach is specific controllers for each subclass. It simplifies the controller code, but also means many simple controllers for the many procedure subclasses. Can work out the shared Procedure details with a partial view. How to get to construct the URL to get to the controller/action in the first place? Time to not think about it. Hopefully someone can show me the light. Thanks in advance.

  • What would be the best approach for this?

    - by chobo
    I have a site which has an area that requires authentication. Right now I use the roles attribute on all the controllers in that area, and I run a query to retrieve that users ID, and all their settings. It seems like a code or design smell to me that I am retrieving the userid and settings each time a controller in that area loads up? I'm not sure if I should be using sessions, or if ASP.Net MVC 2.0 provides some unique way to handle this. Another concern is security. Overall, I don't really know which way to turn. Design wise I would like the userId and settings retrieved only once when the user logs into the area. Right now I grab the userId each time a controller loads up, and then if required, I query the database for their settings each time as well.

  • How do I use a named_scope to filter records in my model

    - by kibyegon
    I have a model "Product" with a "description" field. Now I want to have a link in the index page that when clicked will show all products where the description is blank (empty). In the model I have defined a named_scope like this named_scope :no_description, :conditions => { :description => "" } I have checked that the named_scope works by calling Product.no_description.count on the console. As far as I know, the controller is then supposed to handle the filter request from the link on the "index" action but be able to distinguish it from the default which is view all products. def index @products = Product.all ... My problem is getting the controller handle the different request, what route to setup for the link on the view and the actual link on the view. Hope I explained my problem.

  • codeigniter not being able to get the full param from url?

    - by bnelsonjax
    Im having a weird issue that i cant seem to fix. It's dealing with viewing a company and adding a location to that company. when viewing a company, my url would look like this: domain.com/company/view/415 So clearly 415 is the ID of company, the company shows up correctly on my company view page. Now comes the weird part. when clicking on an "Add Location" link, which would take me to : domain.com/location/add/415 so once again this should be saying Location / Add / 415 (company ID 415) on this page, if i do it will echo 4 (instead of 415...the company id) if the company id is 754, the php echo $data['id'] would echo 7 (instead of 754). So its stripping the last 2 numbers off the Company ID. Here is my controller: public function add($id) { if (isset($_POST["add"])) { $this->Equipment_model->add($id); redirect('company/view/'.$id); } $data['locations'] = $this->Equipment_model->get_locations($id); $data['data'] = $id; $this->load->view('templates/header'); $this->load->view('equipment/add', $data); $this->load->view('templates/footer'); } here is my .htaccess RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-l RewriteCond $1 !^(index\.php|css|font|img|js|themes) RewriteRule ^(.*)$ index.php/$1 [QSA,L] Because my php/codeigniter experience is limited, maybe my terminology is off, so i created a video and uploaded it to twitch, here is the link if you wanna see what im talking about: http://www.twitch.tv/bnelsonjax/b/420079504 if anyone could help i'd be so grateful, I've been stuck on this for about a week. UPDATE ok now we are getting somehwere, when i change controller to: public function add($id) { if (isset($_POST["add"])) { $this->Equipment_model->add($id); redirect('company/view/'.$id); } $data['locations'] = $this->Equipment_model->get_locations($id); $data['data'] = $id; $data['cid'] = $id; $this->load->view('templates/header'); $this->load->view('equipment/add', $data); $this->load->view('templates/footer'); $this->output->enable_profiler(TRUE); } if i add the following to the view page: <?php echo $data['id']; ?> it echos: 7 this one: <?php echo $cid; ?> it echos 766 (CORRECT ONE) this one: <?php echo $data['cid']; ?> it echos 7 my question then is why if the controller show: $data['data'] = $id; $data['cid'] = $id; does only the one thats $data['cid'] echo correctly?

  • Rails show view of one model with form for adding one child - nested attributes vs seperate controll

    - by SWR
    I have a basic two tiered model structure: Articles - Comments with one Article having many comments. What is the best way to add a "Add a comment" form to the bottom of the Articles show page? nested_attributes is overkill as I don't want to be able to edit all of the comments on the page, just to add one more. Is the best way even with Rails 2.3 still to make a separate controller and embed a form_for pointing to the other controller into the Articles show view? If so, how do I get validation errors to return to the article display page? I don't want to make a separate comment page/view... thanks

  • Can I use accepts_nested_attributes_for with checkboxes in a _form to select potential 'links' from a list

    - by Ryan
    In Rails 3: I have the following models: class System has_many :input_modes # name of the table with the join in it has_many :imodes, :through => :input_modes, :source => 'mode', :class_name => "Mode" has_many :output_modes has_many :omodes, :through => :output_modes, :source => 'mode', :class_name => 'Mode' end class InputMode # OutputMode is identical belongs_to :mode belongs_to :system end class Mode ... fields, i.e. name ... end That works nicely and I can assign lists of Modes to imodes and omodes as intended. What I'd like to do is use accepts_nested_attributes_for or some other such magic in the System model and build a view with a set of checkboxes. The set of valid Modes for a given System is defined elsewhere. I'm using checkboxes in the _form view to select which of the valid modes is actually set in imodes and omodes . I don't want to create new Modes from this view, just select from a list of pre-defined Modes. Below is what I'm currently using in my _form view. It generates a list of checkboxes, one for each allowed Mode for the System being edited. If the checkbox is ticked then that Mode is to be included in the imodes list. <% @allowed_modes.each do |mode| %> <li> <%= check_box_tag :imode_ids, mode.id, @system.imodes.include?(modifier), :name => 'imode_ids[]' %> <%= mode.name %> </li> <% end %> Which passes this into the controller in params: { ..., "imode_ids"=>["2", "14"], ... } In the controller#create I extract and assign the Modes that had their corresponding checkboxes ticked and add them to imodes with the following code: @system = System.new(params[:system]) # Note the the empty list that makes sure we clear the # list if none of the checkboxes are ticked if params.has_key?(:imode_ids) imodes = Mode.find(params[:imode_ids]) else imodes = [] end @system.imodes = imodes Once again that all works nicely but I'll have to copy that cludgey code into the other methods in the controller and I'd much prefer to use something more magical if possible. I feel like I've passed off the path of nice clean rails code and into the forest of "hacking around" rails; it works but I don't like it. What should I have done?

  • How to Pass complex objects in ASP.NET MVC using Get parameters?

    - by VJ
    I am wanting to pass something like the following to my view from my controller via GET not POST: public class MyDTO { public string val1 { get; set; } public string val2 { get; set; } public MyObject obj { get; set; } } public class MyObject { public int SomeInt { get; set; } public string ACoolValue { get; set; } public string YetAnotherCoolValue { get; set; } } And then the controller would like like this. (Note it is a GET): public ActionResult MyView(MyDTO dto) { return View(dto) } The problem is that the instance of MyObject is coming back as null, where val1 and val2 have data. Has anyone run across this?
