  • Ways to call Blocks within Magento: createBlock vs Layout xml file

    - by N. B.
    Context: I'm trying to include Adminhtml blocks in the frontend of the site to replace some of the user account blocks. The first thing I'm trying to do is simply display the block on the correct page. I can replace the entire page by setting the Body of the response inside the controller, but I'm having a hard time including the block in the layout xml file and then calling it within the template. Why would I be able to create an adminhtml/sales_order_grid from Mage_Sales_OrderController using createBlock: $this->getResponse()->setBody($this->getLayout()->createBlock('adminhtml/sales_order_grid')->toHtml()); But not from a frontend layout, using a declaration <block type="adminhtml/sales_order_grid" name="orders_widget"/> within app/design/frontend/default/default/layout/sales.xml The latter produces an error without a stack trace: Fatal error: Call to a member function toHtml() on a non-object in app/code/core/Mage/Core/Model/Layout.php on line 526 Thanks for any guidance!

  • Internationalization of static pages with Rails

    - by Gavin
    I feel like I'm missing something really simple and I keep spinning my wheels on this problem. I currently have internationalization working throughout my app. The translations work and the routes work perfectly. At least, most of the site works with the exception of the routes to my two static pages, my "About" and "FAQ" pages. Every other link throughout the app points to the proper localized route. For example if I select "french" as my language, links point to the appropriate "(/:locale)/controller(.:format)." However, despite the changes I make throughout the app my links for the "About" and "FAQ" refuse to point to "../fr/static/about" and always point to "/static/about." To make matters stranger, when I run rake routes I see: "GET (/:locale)/static/:permalink(.:format) pages#show {:locale=/en|fr/}" and when I manually type in "../fr/static/about" the page translates perfectly. My Routes file: devise_for :users scope "(:locale)", :locale => /en|fr/ do get 'static/:permalink', :controller => 'pages', :action => 'show' resources :places, only: [:index, :show, :destroy] resources :homes, only: [:index, :show] match '/:locale' => 'places#index' get '/'=>'places#index',:as=>"root" end My ApplicationController: before_filter :set_locale def set_locale I18n.locale=params[:locale]||I18n.default_locale end def default_url_options(options={}) logger.debug "default_url_options is passed options: #{options.inspect}\n" { :locale => I18n.locale } end and My Pages Controller: class PagesController < ApplicationController before_filter :validate_page PAGES = ['about_us', 'faq'] def show render params[:permalink] end def validate_page redirect_to :status => 404 unless PAGES.include?(params[:permalink]) end end I'd be very grateful for any help ... it's just been one of those days. Edit: Thanks to Terry for jogging me to include views. <div class="container-fluid nav-collapse"> <ul class="nav"> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown"><%= t(:'navbar.about') %><b class="caret"></b></a> <ul class="dropdown-menu"> <li><%=link_to t(:'navbar.about_us'), "/static/about_us"%></li> <li><%=link_to t(:'navbar.faq'), "/static/faq"%></li> <li><%=link_to t(:'navbar.blog'), '#' %></li> </ul> </li>

  • log4net - configure using multiple configuration files

    - by Gai
    Hi, I have an application consisting of a host and pluggable modules (plugins). I want to be able to configure log4net for the host and for each of the other modules. Each of them should have its own configuration file and each will log to a different file. Only the host has an App.config file. The plugins have their own config file containing the log4net config sections. Calling XmlConfigurator.Configure from one of the plugins overrides the host's app.config log4net definitions. Is there an easy way to append configurations instead of overriding them? Thanks, Gai.

  • gwt typeahead missing

    - by arinte
    I have a GWT app with a bunch of textboxes. In firefox I would expect that when I type a word in a textbox that I have already typed in and submitted, that firefox would offer to autocomplete that text. But for this GWT app it is not happening. Also in IE it seems that none of my css stuff is loaded. And when I IE developer tools on my GWT page, it can focus in on any of the textboxes it just focuses on the encompassing DIV around all the textboxes.

  • Migrating from Forms to WPF

    - by Jason Williams
    We're considering migrating a WinForms app to WPF, but are just starting on the WPF learning curve now that 4.0 is out. What I'd like to do is migrate our application commands (cut, copy, paste, etc) to a WPF-like command-binding system, while still running as a WinForms app - but in such a way as to make the migration easy when we go ahead with WPF. The ideal approach would be to implement our commands using the WPF command interfaces, classes and events directly, and simply hooking the WinForms events up to them with our own dispatcher. Has anyone tried something like this or know if it might be possible?

  • Having all Views in the Shared folder - works but is throwing "caught exceptions". Performance conc

    - by Scott
    Hi everyone, I have a simple but heavily used app done in VS2010/MVC2. I didn't like having separate folders for each view/controller and so have all the views in the Shared folder. It's working fine but while debugging in VS, I noticed that it's throwing IO "caught exceptions" since it seems to be looking in the [FolderName]/[ViewName] folder before going down to the Shared folder. Again, the app runs fine but I'm concerned that all these "caught exceptions" will have a minor performance impact since they do have a cost in via the CLR. Is there any way I can configure the Routing so that it will only look in the Shared folder? Thanks.

  • Problem with Classes in Python..

    - by Gui
    Ok guys, I'm really new at python (and programming itself) so sorry for my ignorance, but I really needed to ask this. So im doing a wxPython project where I added several tabs for a notebook (each tab of the notebook = a class) and there is one tab where I added a checkbox (in a tab, lets call it for example Tab1), and what I want is that when someone checks it, a button that exists in other tab (class called for example tab2) gets hidden where previously it was being shown. Well I see that it isn't hard to accomplish this, but my problem is the classes (tab1 and tab2, in this example). I've been trying to figure it out by searching but I guess im not searching hard enough because I just can't get it right. If they were in the same class I wouldn't have a problem, but as they are in different classes, im having a huge struggle with this. Hope someone can help me, and sorry for my ignorance once again.

  • How does jQuery .data() work?

    - by kazanaki
    My Javascript knowledge is pretty limited. Instead of asking several javascript questions I got the "message" from Stack overflow and started using jQuery right away in order to save me some time. However several times I do not undestand the "magic" behind jQuery and I would love to learn the details. I want to use .data() in my application. The examples are very helpful. I do not understand however WHERE these values are stored. I inspect the webpage with Firebug and as soon as .data() saves an object to a dom element, I do not see any change in Firebug (either HTML or Dom tabs). I tried to look at jQuery source, but it is very advanced for my Javascript knowledge and I lost myself. So the question is: Where do the values stored by jQuery.data() actually go? Can I inspect/locate/list/debug them using a tool?

  • IIS 6 session timing out a lot quicker than expected

    - by Echiban
    I am working with an web application that has its sessions timing out a lot quicker than expected. We expected a timeout of 15 minutes but it's timing out at 3-4 minutes. Info about environment: IIS6 classic ASP / COM+ app timeout OK on current PROD, much quicker in dev / QA environments We already disabled app pool recycling, and even put IIS in isolation mode - no effect HTTP err log doesn't display any lines when session times out We've done a close comparison of PROD and DEV / QA environments, and given we use virtual machines on all of them, settings should be preserved. I tried to find IIS blog notes from David Wang but many of them now have HTTP 404 errors, and I don't know what else to do. Please help! At the very least, is there a way to get IIS to log every time a session expires? At the very least some means of logging / debugging IIS would be useful. Thanks in advance.

  • Strange tab ordering when creating controls after postback

    - by Crackerjack
    I have a button that opens a panel in a popup window and then performs a postback to retrieve data from the server and render some controls. Some of the controls are textboxes and some are dropdown lists and can be in any order. Everything works fine when tabbing through the textbox controls. But when tabbing from the first dropdown contorl found, the tab order 'gets lost' and it starts tabbing from the first control again. When I tab to the same dropdown list the second time 'round, it correctly tabs to the next control. Does anyone know what might be going on? Example: TextBox1 (Tab -> focus set to 'TextBox2') TextBox2 (Tab -> focus set to 'DropDown1') DropDown1 (Tab -> focus goes back up to 'TextBox1' - wtf?) TextBox3 Update: The TabIndex attribute is set on all controls.

  • How does Windows Task Scheduler in Win7 recognize a failed task?

    - by lakeman
    Hello, I am working with Windows 7 and I have an application that returns zero (0x0) when successful and one (0x1) on error situations. I have scheduled this app using Windows Task Scheduler. I have checked the option boxes "If the task fails, restart every" and "Attempt to restart up to:". I thought that a non-zero return code from the app would be enough to trigger the task to be restarted after the given interval. But nothing happens. Any ideas what could be the issue? I tried to google it but did not found anything relevant.

  • Why would a FaceBook application "work" on a profile, but not a page?

    - by ed.talmadge
    I made a FaceBook application that works fine on profiles, but I can't figure out how to get it to show on a FaceBook page. For example, after I visit the application canvas URL, allow the application, then edit application settings and "add" to box and tab view... I cannot click the "plus" symbol to the left of the tabs in order to add a tab for the application. It does not appear in the list of available applications. Meanwhile, the application is working/showing up on profiles with no issues. I DID check the "Installable to Pages" checkbox on the application (authentication tab) settings. What could cause this? Here is the application canvas URL: http://apps.facebook.com/russian_girls/

  • Dragging Files on the Dock Icon

    - by enchilada
    I know how handle dragging of files on the dock icon, and it has been asked before. However, I'm wondering, can I somehow get more control? For example, can I make the dock icon reject files that are not in the user's folder and allow only files that are in the user's folder? I'd rather do that instead of the app appearing as if it handles files outside the user's folder, and then within the app delegate afterwards reject the files by detecting the file paths. That doesn't seem good from a user's perspective.

  • Why is 'heroku create' doing nothing?

    - by vlasits
    I opened a heroku account. I followed the instructions on http://docs.heroku.com/quickstart. I have a working rails app which I have deployed successfully elsewhere. I have a github account that works. I have a local git repository for my rails app. I installed the heroku gem. It shows up in my gem list. I typed 'heroku create' at the command prompt... My command console showed that it was thinking about it, but did nothing. No errors. No action. Possible related facts: I am using a Windows 7 machine. I have also failed miserably at deploying with capistrano with a similar--issue command, get no response--pattern.

  • flex chat/telnet application send/receive same window in TextArea

    - by Renassaince Geek
    Hi there, Just wanting to know if anybody has seen an example of a telnet/chat or other console like FLEX application where you can use the same TextArea as input/ouput area. I've been trying to modify the app at: http://livedocs.adobe.com/flex/3/html/17_Networking_and_communications_8.html but so far, computer says no. All the implementations I've seen use a combination of TextInput and TextArea. The challenge is that we'll be using this app to telnet into some old routers and we'll need to do a fair amount of copy/pasting. Based on what I've seen, it seems that I would need to point the mouse into the TextInput in order to be able to right click and paste, which is not very sleak..... Your thoughts, Fran

  • Why can't I store a float value - it's always zero!

    - by just_another_coder
    I have a view controller that is created by the app delegate - it's the first one shown in the app. In its interface I declare float lengthOfTime; I also set it as a property: @property (nonatomic) float lengthOfTime; And in it's implemetation: @synthesize lengthOfTime; In the class viewDidLoad method, I set the value: self.lengthOfTime = 3.0f; However, after this, the value is always zero. No errors, no compile warnings, nothing. Just zero. The class is instantiated, it is showing in the view, so I'm pretty sure it's not a nil reference. I've searched all over Google and can't figure it out. What's going on?!? :(

  • Facebook Graph - does the user "like" my page?

    - by Ican Zilb
    I am trying to upgrade my iPhone app to use the new facebook graph api. One thing I cannot find is how to find out if the current user connected from my app to facebook is a fan of my facebook page - (i.e. in the new paradigm - whether the user likes my page) In the Rest Api there was a function isFan, but not in the Graph. I can get all items the user likes and search whether one of them is my page, but certainly there must be an easier way instead of going trough thousands of records each time I must check whether he is a fan, right? If someone already figured it out how to do that from their new docs, I'll really appreciate if you share it with me.

  • Silverlight data-driven application with NHibernate

    - by Tigraine
    Hi Guys, this is more of a subjective Question, but I'll ask it anyway. I'm about to develop a very data-centric application that has to run inside the browser. The frontend will be Silverlight, backed by a Fluent NHibernate service that runs server side. The problem here is: Wherever I look for data-driven silverlight app I wind up finding Silverlight RIA services examples, but nothing on how to build this without some ADO.NET stuff involved. I have little to no knowledge in WCF so far, but from the limited research I did it seems like WCF is pretty much the only way to let the client talk to the server. Are there any tutorials/best practices on how to write a Silverlight MVVM app that provides CRUD for a non-EF database? Suggestions would be very much appreciated. Thanks PS: I can't use .NET remoting. The backend has to run on IIS6 :(

  • to-many Core Data fetch request behaves oddly with a new store

    - by Giao
    I have two entities, Department and Person. Department has a to-many relationship to Person. The Person entity has a hireDate property. I'm using the predicate "count(person) = 0 OR none person.hireDate %@" to find Departments without any Persons in them or Departments that haven't hired anyone since a recent date. When the app first starts up (new user experience) and Departments are inserted and no Person have been inserted, the fetch request with this predicate returns nothing. However, if I create insert a new Person entity and delete it, then save the store, the fetch request will return all the Departments. I've found a work around where, I just insert a new Person and delete it, then save the store, the fetch request as I expected it to work. I've found that inserting a new Person and deleting it without saving will not correct the problem. Is this a bug with Core Data or is this a bug with how I've designed my app?

  • Is it hacky to manually construct JSON and manually handle GET, POST instead of using a proper RESTful API for AJAX functionality?

    - by kliao
    I started building a Django app, but this probably applies to other frameworks as well. In Backbone.js methods that call the server (fetch(), create(), destroy(), etc.), should you be using a proper RESTful API such as one provided by Tastypie or Django-Piston? I've founded it easier and more flexible to just construct the JSON in my Django Views, which are mapped to some URLs that Backbone.js can use. Then again, I'm probably not leveraging Tastypie/Django-Piston functionality to the fullest. I'm not ready to make a full-fledged RESTful API for my app yet. I simply would like to use some of the AJAXy functionality that Backbone.js supports. Pros/Cons of doing this?

  • Displaying Photos on iPhone

    - by Bjorn S.
    Hi all, I'm working on an iPhone app and I need to be able to display images to users. I have already gotten the code that takes the photo and stores it into the filesystem working well. Now I just need to figure out how to display the image. I've looked at the Three20 project I've read about on a few of the posts here, but it seems a bit cumbersome and like an extra dependency to import link and combine all of the Three20 library into my little app. Are there any other ways or a more streamlined library that will let me display photos to my users? Thanks! B.

  • UITableView setting standalone delegate object?

    - by fuzzygoat
    Hi have setup a sample application using a UITableView. Initially I did this by conforming my controller to and , added a tableView in IB and connected "datasource" & "delegate" to Files Owner. It all works so thats good. What I have been trying out is creating my own class for the delegate. I created a new class and added and , but quickly found I could not connect the tableViewdataSource / delegate. To solve this I added an "Object" (NSObject) in IB and set it to my new class. I then connected the dataSource and delegate outlets to this object. It sort of works, the app runs and displays the tableView, but when I try and scroll the table the app crashes. Can I ask if I am going about this the right way? gary
