  • STI and accepts_nested_attributes_for in rails

    - by ryanshackintosh
    I have models as follows: class Entity < ActiveRecord::Base has_many :addresses accepts_nested_attributes_for :addresses, :reject_if => lambda { |a| a[:label].blank?} , :allow_destroy => true end class Client < Entity before_save :set_type private def set_type self.type = "Client" end end class Address < ActiveRecord::Base belongs_to :entity end I have recently implemented accepts_nested_attributes_for on the /clients/new form, as follows: <% form_for(@client, :html => {:class => 'form'}) do |f| -%> <%= f.label :name %> <%= f.text_field :name -%> <%= f.label :phone %> <%= f.text_field :phone %> <% f.fields_for :addresses do |a| %> <%= a.label :street %> <%= a.text_field :street%> <%= a.label :city %> <%= a.text_field :city %> <% end %> <% end %> And my controller as follows: class ClientsController < ApplicationController before_filter :load_client , :except => [:index, :new, :create, :render_clients] def new @client = Client.new @client.addresses.build end def create @client = Client.new(params[:client]) if @client.save flash[:notice] = 'Client has been successfully added' redirect_to @client else render :action => 'new' end end The issue is that when the record is saved it gives an error stating: "Entity can't be blank" I assume it is something to do with the fact that a 'Client' and not an 'Entity' is being added. Can anyone point me in the right direction?

  • BlackBerry 5.0 causing full menu to show on navigationClick

    - by jwadsack
    I have a BlackBerry app that is built for 4.5.x SDK. The first page of the app shows a list of fields and each field can be highlighted and clicked. The click action shows a new view with additional information about the field. This all works fine in 4.5, 4.6 and 4.7 and on the sim with 5.0. On a real 9000 running 5.0, when clicking the trackball on an item in the list, the full menu is showing rather than the click event getting consumed (or even fired) for the field. The view is derived from MainScreen and looks something like this: public class ListView extends MainScreen { public ItemCollection list = new ItemCollection; protected void sublayout( int maxWidth, int maxHeight ) { int i = 1; while(( item == (Item)list.nextElement()) != null) { ItemField field = new ItemField(item, i++); add(field); } } } This class does not consume navigationClick, but shouldn't need to, right? The field class does consume navigationClick event: public class ItemField extends Field { protected boolean navigationClick(int status, int time) { controller.showDeal(item.id, Session.current); return true; } } Is there something that changed in 5.0 that I need to add to have this app work the same for all platforms?

  • How to set background color of tableView

    - by Praveen
    Hi Folks, I have tried all the way but could not succeed to set backgroundColor of TableView. setting tableView.backgroundColor and/or cell.backgroundColor to clearColor didn't work when the parent view controller was UIViewContoller. My nib file structure is FileOwner View UITableView (Note: i set the TableView to groupedTable section) First attempt, I created the UIView in the code viewDidLoad UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 160, 300)] autorelease; [view setBackgroundColor:UIColor blueColor]; // color it just to see if it is created at the right place [self.tableView sendSubViewToBack:view]; It works but it hides the content of cell. I am able to see the content of header but not cell content. (But when i change the co-ordinate of view(0,150,160,300) then i am able to see the cell's content but then it loose the backgroundColor of tableview. Second attempt, I created the imageView View ImageView UITableView and set the self.tableView.backgroundColor = [UIColor clearColor]; but did not work. I googled but did not the peaceful answer.

  • Codeigniter: validation problem

    For some reason a user can login with any password, first I thought I forgot to check for the password but I didn't... and I just cant find the problem here is the model: /*#######################################################*/ function validate() /*#######################################################*/ { $this->db->where('username', $this->input->post('username')); $this->db->where('password', md5($this->input->post('password'))); $q = $this->db->get('user_extra'); if($q->num_rows() == 1): return true; else: return false; endif; }//end of function validate() The controller /*#######################################################*/ function validate_credentials() /*#######################################################*/ { $this->load->model('membership_model'); $this->load->library('form_validation'); $this->form_validation->set_rules('username', 'Name', 'trim|required'); $this->form_validation->set_rules('password', 'password', 'trim|required'); if(!$this->membership_model->validate()): $this->form_validation->set_message('check_login', 'Login not correct, please try again.'); endif; if($this->form_validation->run() == FALSE): $this->index(); else: $this->membership_model->userinfo($this->input->post('username')); //should redirect to last view redirect($this->session->flashdata('redirect_url')); endif; }// end of validate_credentials()

  • Multiselect tranfer in zend

    - by niriza
    I want to transfer the selected value of Zend_Form_Element_Multiselect to another multiselect element of zend form. I tried this with JQuery it works but when I try to populate the form I get a problem what should I do in my controller. My code look like this: Form: $form['core'] = new Zend_Form_Element_Multiselect('core'); foreach ($results as $row) { $form['core']-addMultiOption($row['id'],$row['competencies']); } $form['core']-setLabel('Core competencies')-setAttrib('id','select1'); $form['core_competency'] = new Zend_Form_Element_Multiselect('core_competency'); foreach ($results as $row) { $form['core_competency']-addMultiOption($row['id'], ''); } $form['core_competency']-setAttrib('id','select2'); $form['subsidiary'] = new Zend_Form_Element_Multiselect('subsidiary'); foreach($results as $row) { $form['subsidiary']-addMultiOption($row['id'],$row['competencies']); } $form['subsidiary']-setLabel('Subsidiary competencies'); $form['subsidiary_competency'] = new Zend_Form_Element_Multiselect('subsidiary_competency'); $form['subsidiary_competency']-addMultiOption('',''); $form['save'] = new Zend_Form_Element_Submit('competencies'); $form['save']-setLabel('Save')-setValue('competencies') -setAttrib('id','competencies-save'); $this-addElements($form); $this-setMethod('post');

  • Stop lazy-loading images?

    - by Greg
    Here's the issue – I followed along with the Apple lazy-load image sample code to handle my graphical tables. It works great. However, my lazy-load image tables are being stacked within a navigation controller so that you can move in and out of menus. While all this works, I'm getting a persistent crash when I move into a table then move immediately back out of it using the "back" button. This appears to be a result of the network connections loading content not being closed properly, or calling back to their released delegates. Now, I've tried working through this and carefully setting all delegates to nil and calling close on all open network connections before releasing a menu. However, I'm still getting the error. Also – short posting my entire application code into this post, I can't really post a specific code snippet that illustrates this situation. I wonder if anyone has ideas for tasks that I may be missing? Do I need to do anything to close a network connection other than closing it and setting it to nil? Also, I'm new to debugging tools – can anyone suggest a good tool to use to watch network connections and see what's causing them to fail? Thanks!

  • C#: Determine Type for (De-)Serialization

    - by dbemerlin
    Hi, i have a little problem implementing some serialization/deserialization logic. I have several classes that each take a different type of Request object, all implementing a common interface and inheriting from a default implementation: This is how i think it should be: Requests interface IRequest { public String Action {get;set;} } class DefaultRequest : IRequest { public String Action {get;set;} } class LoginRequest : DefaultRequest { public String User {get;set;} public String Pass {get;set;} } Handlers interface IHandler<T> { public Type GetRequestType(); public IResponse HandleRequest(IModel model, T request); } class DefaultHandler<T> : IHandler<T> // Used as fallback if the handler cannot be determined { public Type GetRequestType() { return /* ....... how to get the Type of T? ((new T()).GetType()) ? .......... */ } public IResponse HandleRequest(IModel model, T request) { /* ... */ } } class LoginHandler : DefaultHandler<LoginRequest> { public IResponse HandleRequest(IModel mode, LoginRequest request) { } } Calling class Controller { public ProcessRequest(String action, String serializedRequest) { IHandler handler = GetHandlerForAction(action); IRequest request = serializer.Deserialize<handler.GetRequestType()>(serializedRequest); handler(this.Model, request); } } Is what i think of even possible? My current Solution is that each handler gets the serialized String and is itself responsible for deserialization. This is not a good solution as it contains duplicate code, the beginning of each HandleRequest method looks the same (FooRequest request = Deserialize(serializedRequest); + try/catch and other Error Handling on failed deserialization). Embedding type information into the serialized Data is not possible and not intended. Thanks for any Hints.

  • integrating jquery with AJAX using MVC for ddl/html.dropdownlist

    - by needhelp
    the situation: a user on the page in question selects a category from a dropdown which then dynamically populates all the users of that category in a second dropdown beside it. all the data is being retrieved using LinqtoSQL and i was wondering if this can be done a) using html.dropdownlist in a strongly typed view? b) using jquery to trigger the ajax request on selected index change instead of a 'populate' button trigger? sorry i dont have code as what i was trying really wasnt working at all.

  • Extended Zend_Db_Table_Row_Abstract does not return values

    - by WesleyE
    Hi, I'm quite new to Zend and the database classes from it. I'm having problems mapping a Zend_Db_Table_Row_Abstract to my rows. The problem is that whenever I try to map it to a class (Job) that extends the Zend_Db_Table_Row_Abstract class, the database data is not receivable anymore. I'm not getting any errors, trying to get data simply returns null. Here is my code so far: Jobs: class Jobs extends Zend_Db_Table_Abstract { protected $_name = 'jobs'; protected $_rowsetClass = "Job"; public function getActiveJobs() { $select = $this->select()->where('jobs.jobDateOpen < UNIX_TIMESTAMP()')->limit(15,0); $rows = $this->fetchAll($select); return $rows; } } Job: class Job extends Zend_Db_Table_Row_Abstract { public function getCompanyName() { //Gets the companyName for this row (Is on another table), just for example } } Controller: $oJobs = new Jobs(); $aActiveJobs = $oJobs->getActiveJobs(); foreach ($aActiveJobs as $value) { var_dump($value->jobTitle); } When I remove the "protected $_rowsetClass = "Job";" line, so that the table row is not mapped to my own class, I get all the jobTitles perfectly. What am I doing wrong here? Thanks in advance, Wesley

  • Error: undefined method `contact' for nil:NilClass

    - by user275801
    I have a ruby/rails/hobo system that someone wrote a couple years ago, that I need to port to the latest version of ruby/rails/hobo. It seems that ruby doesn't care about backward compatibility, so code that used to work in the old app doesn't work anymore: In the observation.rb model file, the old app has this: belongs_to :survey has_one :site, :through => :survey def create_permitted? acting_user == self.survey.contact or acting_user.administrator? end survey.rb model file has this: belongs_to :contact, :class_name => 'User', :creator => true Unfortunately the code in observation.rb doesn't work under the new ruby/rails/hobo, and it gives me the error: NoMethodError in Observations#index Showing controller: observations; dryml-tag: index-page where line #1 raised: undefined method `contact' for nil:NilClass Extracted source (around line #1): 0 Rails.root: /home/simon/ruby/frogwatch2 Application Trace | Framework Trace | Full Trace app/models/observation.rb:48:in `create_permitted?' How should the "create_permitted" method be changed? I'm finding that the documentation for ruby/rails/hobo is pretty atrocious (which is fair enough as it is free software). Also I don't even know how to begin searching for this on google (i've been trying for days). Please help! :)

  • Representing versions of objects with CakePHP

    - by user636901
    Hi people, Have just started to get into CakePHP since a couple of weeks back. I have some experience with MVC-frameworks, but this problem holds me back a bit. I am currently working on a model foo, containing a primary id and some attributes. Since a complete history of the changes of foo is necessary, the content of foo is saved in the table foo_content. The two tables are connected through foo_content.foo_id = foo.id, in Cake with a foo hasMany foo_content-relationship. To track the versions of foo, foo_content also contains the column version, and foo itself the field currentVersion. The version is an number incremented by one everytime the user updates foo. This is an older native PHP-app btw, to be rewritten on top of Cake. 9 times out of 10 in the app, the most recent version (foo.currentVersion) is the db-entry that need to be represented in the frontend. My question is simply: is there someway of representing this directly in the model? Or does this kind of logic simply need to be defined in the controller? Most grateful for your help!

  • Codeigniter PHP - loading a view at an anchor point

    - by James Billings
    I have a form at the bottom of a long page, if a user fills out the form but it doesn't validate the page is reloaded in the typical codeigniter fashion: $this->load->view('template',$data); however because the form is way down at the bottom of the page I need the page to load down there like you do with HTML anchors. Does anyone know how to do this in codeigniter? I can't use the codeigniter redirect(); function because it loses the object and the validation errors are gone. Other frameworks I've used like Yii you can call the redirect function like: $this->redirect(); which solves the problem because you keep the object. I've tried using: $this->index() within the controller which works fine as a redirect but the validation errors are in another method which is where the current page is loaded from: $this->item($labs) but when I use this it get stuck in a loop Any ideas? I've seen this question a lot on the net but no clear answers. I'm researching using codeigniter "flash data" but think it's a bit overkill. cheers.

  • Beginner MVC question - Correct approach to render out a List and details?

    - by fizzer
    I'm trying to set up a page where I display a list of items and the details of the selected item. I have it working but wonder whether I have followed the correct approach. I'll use customers as an example I have set the aspx page to inherit from an IEnumerable of Customers. This seems to be the standard approach to display the list of items. For the Details I have added a Customer user control which inherits from customer. I think i'm on the right track so far but I was a bit confused as to where I should store the id of the customer whose details I intend to display. I wanted to make the id optional in the controller action so that the page could be hit using "/customers" or "customers/1" so I made the arg optional and stored the id in the ViewData like this: public ActionResult Customers(string id = "0") { Models.DBContext db = new Models.DBContext(); var cList = db.Customers.OrderByDescending(c => c.CustomerNumber); if (id == "0") { ViewData["CustomerNumber"] = cList.First().CustomerNumber.ToString(); } else { ViewData["CustomerNumber"] = id; } return View("Customers", cList); } I then rendered the User control using RenderPartial in the front end: <%var CustomerList = from x in Model where x.CustomerNumber == Convert.ToInt32(ViewData["CustomerNumber"]) select x; Customer c = (Customer)CustomerList.First(); %> <% Html.RenderPartial("Customer",c); %> Then I just have an actionLink on each listed item: <%: Html.ActionLink("Select", "Customers", new { id = item.CustomerNumber })% It all seems to work but as MVC is new to me I would just be interested in others thoughts on whether this is a good approach?

  • Login fails when recreating database with Code First

    - by Mun
    I'm using ASP.NET Entity Framework's Code First to create my database from the model, and the login seems to fail when the database needs to be recreated after the model changes. In Global.asax, I've got the following: protected void Application_Start() { Database.SetInitializer(new DropCreateDatabaseIfModelChanges<EntriesContext>()); // ... } In my controller, I've got the following: public ActionResult Index() { // This is just to force the database to be created var context = new EntriesContext(); var all = (from e in context.Entries select e).ToList(); } When the database doesn't exist, it is created with no problems. However, when I make a change to the model, rebuild and refresh, I get the following error: Login failed for user 'sa'. My connection string looks like this: <add name="EntriesContext" connectionString="Server=(LOCAL);Database=MyDB;User Id=sa;Password=password" providerName="System.Data.SqlClient" /> The login definitely works as I can connect to the server and the database from Management Studio using these credentials. If I delete the database manually, everything works correctly and the database is recreated as expected with the schema reflecting the changes made to the model. It seems like either the password or access to the database is being lost. Is there something else I need to do to get this working?

  • using action helpers in Zend Framework 1.8

    - by Nasser
    Hi am starting off with Zend Framework and have a question about action helpers. My first application is a simple authentication system (following a tutorial from a book). The registration and authentication seems to work fine but the redirect doesn't. I have a customer controller that has this among others: class CustomerController extends Zend_Controller_Action { // some code here...... public function authenticateAction() { $request = $this->getRequest(); if (!$request->isPost()) { return $this->_helper->redirector('login'); } // Validate $form = $this->_forms['login']; if (!$form->isValid($request->getPost())) { return $this->render('login'); } if (false === $this->_authService->authenticate($form->getValues())) { $form->setDescription('Login failed, please try again.'); return $this->render('login'); } return $this->_helper->redirector('index'); } the authenticate url is http://localhost/customer/authenticate and this seems to work fine but it does not redirect. After authentication I get a blank page which looks like its taking me to the index and just sits there. I tried using '/index' instead but that did not help either. Do I need to do anything special to make the redirector helper work? I have a logout action which behaves the same.

  • And now for a complete change of direction from C++ function pointers

    - by David
    I am building a part of a simulator. We are building off of a legacy simulator, but going in different direction, incorporating live bits along side of the simulated bits. The piece I am working on has to, effectively route commands from the central controller to the various bits. In the legacy code, there is a const array populated with an enumerated type. A command comes in, it is looked up in the table, then shipped off to a switch statement keyed by the enumerated type. The type enumeration has a choice VALID_BUT_NOT_SIMULATED, which is effectively a no-op from the point of the sim. I need to turn those no-ops into commands to actual other things [new simulated bits| live bits]. The new stuff and the live stuff have different interfaces than the old stuff [which makes me laugh about the shill job that it took to make it all happen, but that is a topic for a different discussion]. I like the array because it is a very apt description of the live thing this chunk is simulating [latching circuits by row and column]. I thought that I would try to replace the enumerated types in the array with pointers to functions and call them directly. This would be in lieu of the lookup+switch.

  • CI + Joomla 1.5

    - by DMin
    Hi, This is something that I just cooked up with Joomla and CodeIgniter(CI). I Wrote my database intensive application in CodeIgniter and frontend is Joomla. I'm using Jumi(Joomla Extention) so I can include the CI files inside joomla to basically insert the content generated by CI into Joomla articles. Problem is, you can't include CI files directly using JUMI from joomla because CI tends to route the pages so instead of seeing your joomla page with the CI content, you be redirected to the CI page itself. I did a little work around for this : Made an additional page that just basically does cURL to the CI page - gets the data and echos it out. From jumi, I include this cURL page instead. Couple of questions: I've seen at least a few posts that CI + Joomla is difficult to do(link). 1) Do you see any glaring security issues or possible performance issues? 2) Do you know of a better way to implement this? 3) What do you think of this? Do you think this is a good way to do this? There is one component out there that plugs CI with Joomla but it requires you to have a fresh CI install. It allows only one controller & the download link is down as well.

  • Easier way to populate form data and validation data in Code Igniter?

    - by John
    I'm new to code igniter. I'm following the form validation tutorial found at: http://www.codeignitor.com/user_guide/libraries/validation.html I find I am typing too much in the view to get the form to re-populate. For example, here's what one of my INPUT fields look like: <input type="text" name="email" value="<?=$this->validation->email ? $this->validation->email : $array_db_values['email'] ?>" /> Basically, when the form first loads, it should show a value from the database. If the user alters the value and it fails validation, then the form should post the erroneously submitted value. Does code igniter have a "cleaner" way of rendering this kind of output? Otherwise, I'm going to do something like this in my controller: $array_db_values = getdbresults(); if($_POST['submit']) foreach($_POST as $key=>$val) $array_db_values[$key] = $val; That way, if postback data exists, it will always override database values. Then input fields in my view can simply be: <input type="text" name="email" value="<?=$array_db_values['email'] ?>" /> Is there a better/native CI way to handle this scenario?

For example controller: @vouch = Vouch.last.vouched_user_nickname view: <% Twitter::Search.new(params[:id]).each do |tweet| %> <li> <%= image_tag tweet.profile_image_url %> <% if @vouch.include? tweet.from_user %> <div class="flit_message_containerh"> <u> <a href="http://twitter.com/<%= tweet.from_user %>"> <%= tweet.from_user %></a></u> <%= linkup_mentions(auto_link(h tweet.text)) %> <div class="time_ago"> <%= link_to distance_of_time_in_words_to_now(tweet.created_at) , tweet %> <% else %> <div class="flit_message_container"> <u> <a href="http://twitter.com/<%= tweet.from_user %>"> <%= tweet.from_user %></a></u> <%= linkup_mentions(auto_link(h tweet.text)) %> <div class="time_ago"> <%= link_to distance_of_time_in_words_to_now(tweet.created_at) , tweet %> <% end %> But I'm having trouble doing it for multiple user nicknames. @vouch = Vouch.find(:all, :select => "vouched_user_nickname", :group => 'vouched_user_nickname' ) Any ideas would be greatly appreciated. I'm a rails noob.
