  • E-commerce platform for custom application integration

    - by Zach Smith
    We are building an online subscription-based website and I'm looking for recommendations on which e-commerce platform to use for the checkout process. Requirements include: Only four products. The sign-up process of the site is heavily customized, and after checkout the user should automatically get logged into the subscriber area. Subscriptions will last one year and can be renewed manually. Support for coupons/discount codes at a later point. Since the entire application is custom, we've weighed building a custom checkout but are strongly leaning towards using existing software to avoid having to build lots of admin reporting as well as a coupon engine down the road. The two questions we're pondering are: Is it better to a) build our application custom and use whatever e-commerce software we select just for the payment piece, or b) use the e-commerce software as the basis and build our application around it/as a module/etc? Which e-commerce platform should we use? I've looked into a variety of off the shelf e-commerce software, but it's not clear to me which would be easiest to integrate with. I've researched on the Web and looked at many of the threads on SO to compiled a list of potential candidates: www.magentocommerce.com/ (seems difficult to integrate with) www.prestashop.com/ www.nopcommerce.com/ www.opencart.com/ www.cubecart.com/ www.spreecommerce.com/ www.interspire.com/ www.tradingeye.com/ We're most concerned with the level of effort required with ramping up on the software and then doing the integration with our custom functionality. We're most proficient with PHP, ASP.NET and some ROR and are only considering those technologies. We prefer open source, but would be open to commercial if there's a significant upside. Any experiences with similar projects and advice is greatly appreciated.

  • Load dll's from Environment Variable Path from a service

    - by Paulo Manuel Santos
    We install Matlab Runtime on a machine, then we restart a .net windows service that invokes methods from the Matlab Runtime. The problem is that we receive TypeInitializationException errors until we restart windows. We think this happens because Environment Variables are not changed on services until restart and Matlab uses the %Path% variable to reference it's core DLL's. My question is, do you think I can change the %Path% variable so that Matlab will use it when referencing the core dll's for it's engine? Or is it possible to add a directory to the runtime DLL loading mechanism of .NET so that those Matlab core dll's would be referenced correctly without restarting the machine? Here is the exception we get System.TypeInitializationException: The type initializer for 'MatlabCalculation.Calculation' threw an exception. ---> System.TypeInitializationException: The type initializer for 'MathWorks.MATLAB.NET.Utility.MWMCR' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'mclmcrrt710.dll': Kan opgegeven module niet vinden. (Exception from HRESULT: 0x8007007E) at MathWorks.MATLAB.NET.Utility.MWMCR.mclmcrInitialize() at MathWorks.MATLAB.NET.Utility.MWMCR..cctor() --- End of inner exception stack trace --- at MatlabCalculation.Calculation..cctor() --- End of inner exception stack trace --- at MatlabCalculation.Calculation.Finalize() "Kan opgegeven module niet vinden" = "The specified module not found"

  • jsf and huge web site

    - by darko petreski
    Hi All, I need to program a very huge web site. The site should contain public part with search engine, user registration forms, cart and all other stuff. The private part should contain administrative web application with a lot of data grids, complex edit forms, security checks, services and so on. Also I need very good support for html mailing and pdf exports. Web services are also required. I am considering to use jsf. Can you recommend me books or other stuff where I can find all this info for building what i need? Is seam good option for this? I have looked their site and page seam on production. The sites listed there are far from professional and enterprise. Is there any book that explains how to build complete web site with jsf technology from login, security, sending mails, pdf conversion, time dependent background processes and everything else that big sites needs. I do not have time reading 20 books. In every php book all this stuff is explained but I have not seen a single java book that at least from high view will explain all of this. Regards

  • Help with understanding generic relations in Django (and usage in Admin)

    - by saturdayplace
    I'm building a CMS for my company's website (I've looked at the existing Django solutions and want something that's much slimmer/simpler, and that handles our situation specifically.. Plus, I'd like to learn this stuff better). I'm having trouble wrapping my head around generic relations. I have a Page model, a SoftwareModule model, and some other models that define content on our website, each with their get_absolute_url() defined. I'd like for my users to be able to assign any Page instance a list of objects, of any type, including other page instances. This list will become that Page instance's sub-menu. I've tried the following: class Page(models.Model): body = models.TextField() links = generic.GenericRelation("LinkedItem") @models.permalink def get_absolute_url(self): # returns the right URL class LinkedItem(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') title = models.CharField(max_length=100) def __unicode__(self): return self.title class SoftwareModule(models.Model): name = models.CharField(max_length=100) description = models.TextField() def __unicode__(self): return self.name @models.permalink def get_absolute_url(self): # returns the right URL This gets me a generic relation with an API to do page_instance.links.all(). We're on our way. What I'm not sure how to pull off, is on the page instance's change form, how to create the relationship between that page, and any other extant object in the database. My desired end result: to render the following in a template: <ul> {% for link in page.links.all %} <li><a href='{{ link.content_object.get_absolute_url() }}'>{{ link.title }}</a></li> {% endfor%} </ul> Obviously, there's something I'm unaware of or mis-understanding, but I feel like I'm, treading into that area where I don't know what I don't know. What am I missing?

  • Django: A Result Specific Numeration for Pagination.

    - by TheLizardKing
    Simply put I want what http://www.reddit.com/ and http://news.ycombinator.com/ have to the left of every link. A numerated link starting with 1 and continuing to the next page by means of pagination. I really enjoy using generic views and their built-in pagination for Django and it seems to allow me access to these values if I was on page 3 with 2 items per page. {'MEDIA_URL': ''} {'LANGUAGES': '<<languages>>', 'LANGUAGE_BIDI': False, 'LANGUAGE_CODE': 'en-us'} {'debug': True, 'sql_queries': '<<sql_queries>>'} {'messages': [], 'perms': <django.core.context_processors.PermWrapper object at 0xadedeec>, 'user': <User: thelizardking>} {'first_on_page': 5, 'has_next': True, 'has_previous': True, 'hits': 7, 'is_paginated': True, 'last_on_page': 6, 'links_list': [<Link: Funky Town>, <Link: Apple Jax>], 'next': 4, 'page': 3, 'page_obj': <Page 3 of 4>, 'page_range': [1, 2, 3, 4], 'pages': 4, 'paginator': <django.core.paginator.Paginator object at 0xadf914c>, 'previous': 2, 'results_per_page': 2} I know there is an add filter for templates but that's as close as I think I can get and that really doesn't do what I want. Am I going to have to use a custom template filter here or is there something I am not seeing?

  • Where can I find free and open data?

    - by kitsune
    Sooner or later, coders will feel the need to have access to "open data" in one of their projects, from knowing a city's zip to a more obscure information such as the axial tilt of Pluto. I know data.un.org which offers access to the UN's extensive array of databases that deal with human development and other socio-economic issues. The other usual suspects are NASA and the USGS for planetary data. There's an article at readwriteweb with more links. infochimps.org seems to stand out. Personally, I need to find historic commodity prices, stock values and other financial data. All these data sets seem to cost money however. Clarification To clarify, I'm interested in all kinds of open data, because sooner or later, I know I will be in a situation where I could need it. I will try to edit this answer and include the suggestions in a structured manners. A link for financial data was hidden in that readwriteweb article, doh! It's called opentick.com. Looks good so far! Update I stumbled over semantic data in another question of mine on here. There is opencyc ('the world's largest and most complete general knowledge base and commonsense reasoning engine'). A project called UMBEL provides a light-weight, distilled version of opencyc. Umbel has semantic data in rdf/owl/skos n3 syntax. The Worldbank also released a very nice API. It offers data from the last 50 years for about 200 countries

  • Workaround for GNU Make 3.80 eval bug

    - by bengineerd
    I'm trying to create a generic build template for my Makefiles, kind of like they discuss in the eval documentation. I've run into a known bug with GNU Make 3.80. When $(eval) evaluates a line that is over 193 characters, Make crashes with a "Virtual Memory Exhausted" error. The code I have that causes the issue looks like this. SRC_DIR = ./src/ PROG_NAME = test define PROGRAM_template $(1)_SRC_DIR = $$(SRC_DIR)$(1)/ $(1)_SRC_FILES = $$(wildcard $$($(1)_SRC_DIR)*.c) $(1)_OBJ_FILES = $$($(1)_SRC_FILES):.c=.o) $$($(1)_OBJ_FILES) : $$($(1)_SRC_FILES) # This is the problem line endef $(eval $(call PROGRAM_template,$(PROG_NAME))) When I run this Makefile, I get gmake: *** virtual memory exhausted. Stop. The expected output is that all .c files in ./src/test/ get compiled into .o files (via an implicit rule). The problem is that $$($(1)_SRC_FILES) and $$($(1)_OBJ_FILES) are together over 193 characters long (if there are enough source files). I have tried running the make file on a directory where there is only 2 .c files, and it works fine. It's only when there are many .c files in the SRC directory that I get the error. I know that GNU Make 3.81 fixes this bug. Unfortunately I do not have the authority or ability to install the newer version on the system I'm working on. I'm stuck with 3.80. So, is there some workaround? Maybe split $$($(1)_SRC_FILES) up and declare each dependency individually within the eval?

  • Silverlight 4 Drag and Drop Treeview

    - by Rich
    Does anyone have an example for any of the following scenarios. Given, these are all dynamically populated trees. Not using a Heirarchal data template, but by iterating through object collections manually and appending children at the appropriate level. Treeview1 has 3 levels, but items can only be reordered within their level. So, lets say we have Drives, Folders and Files. Drives can be rearranged in an order, but not put into a Folder. When navigated down one level in a drive, the individual folders can be reordered, but not dragged between drives.. and same with files, only can be reordered, but not moved to a different folder or drive I have 2 treeviews, Treeview1 is the same as #1 above and Treeview2 is like a picklist of available items. A user can drag an item from Treeview2 to Treeview1, but it can only be placed at Treeview1's File Level. The dragged item cannot be a child of a file, or placed at the folder level, nor placed at the drive level. Also, how to handle the Above, On Top, or Below an item. I have yet to come across these examples.

  • Passenger: "Missing these required gems redgreen"

    - by Michael Stum
    Hello, total ruby newbie, trying to setup a Rails/MongoDB application on Mac OS X Snow leopard. Installed Ruby 1.9.1 and RubyGems 1.3.7, which ruby and which gem point to the same directory. I'm using the Snow Leopard built-in apache and Passenger 2.2.11. I'm using the rails template from the mongo-site which seems to work okay overall. The exact error that passenger gives me is: /Users/User/Sites/feuerapp/vendor/rails/railties/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. Use #requirement **Notice: C extension not loaded. This is required for optimum MongoDB Ruby driver performance. You can install the extension as follows: gem install bson_ext If you continue to receive this message after installing, make sure that the bson_ext gem is in your load path and that the bson_ext and mongo gems are of the same version. Missing these required gems: redgreen You're running: ruby 1.9.1.376 at /usr/local/bin/ruby rubygems 1.3.7 at /Users/User/.gem/ruby/1.9.1, /usr/local/lib/ruby/gems/1.9.1 Runrake gems:installto install the missing gems.

  • Left Join with a OneToOne field in Django

    - by jamida
    I have 2 tables, simpleDB_all and simpleDB_some. The "all" table has an entry for every item I want, while the "some" table has entries only for some items that need additional information. The Django models for these are: class all(models.Model): name = models.CharField(max_length=40) important_info = models.CharField(max_length=40) class some(models.Model): all_key = models.OneToOneField(all) extra_info = models.CharField(max_length=40) I'd like to create a view that shows every item in "all" with the extra info if it exists in "some". Since I'm using a 1-1 field I can do this with almost complete success: allitems = all.objects.all() for item in allitems: print item.name, item.important_info, item.some.extra_info but when I get to the item that doesn't have a corresponding entry in the "some" table I get a DoesNotExist exception. Ideally I'd be doing this loop inside a template, so it's impossible to wrap it around a "try" clause. Any thoughts? I can get the desired effect directly in SQL using a query like this: SELECT all.name, all.important_info, some.extra_info FROM all LEFT JOIN some ON all.id = some.all_key_id; But I'd rather not use raw SQL.

  • Timeout reading verity collection - CF8

    - by Gary
    For a long time now I've been having a problem with using the verity search service bundled with ColdFusion 8. The issue is with timeout errors occurring when perfoming any operation on a collection. It's intermittent, and usually occurs after a few operations have been successfully performed. For instance: If I'm adding records to a collection the first, say 15 records, will go through with no problems, but all subsequent records will timeout until the service is rebooted. I'm on a shared server, Windows 2008, 64bit as far as I know. The error I receive is: "An error occurred while performing an operation in the Search Engine library. Error reading collection information.: com.verity.api.administration.ConfigurationException: java.io.IOException: Read timed out" Having spoken to my hosting company, and after doing some research, it's been suggested that the number of collections on a server may cause this issue. I've reduced the amount of collections I use, and there are currently 39 collections on the server. As I'm on a shared server, I have no control over how many collections other customers use, however I've read that the limit is 128 collections, so I don't see why 39 should cause it to become unusable. The collections aren't big, there's maybe around 5,000 records between all of them. Any ideas?

  • Explicit script end tag always converted to self-closing

    - by Jonas
    I'm using xslt to transform xml to an aspx file. In the xslt, I have a script tag to include a jquery.js file. To get it to work with IE, the script tag must have an explicit closing tag. For some reason, this doesn't work with xslt below. <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns="http://www.w3.org/1999/xhtml" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" xmlns:asp="remove"> <xsl:output method="html"/> <xsl:template match="/"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>TEST</title> <script type="text/javascript" src="jquery-1.2.6.js"></script> But if I change the script tag as shown below, it works. <script type="text/javascript" src="jquery-1.2.6.js"> // <![CDATA[ // ]]> </script> I thought that the <xsl:output method="html" /> would do the trick, but it doesn't seem to work? /Jonas

  • Ideas on C# DSL syntax

    - by Dmitriy Nagirnyak
    Hi, I am thinking about implementing a templating engine using only the plain C#/.NET 4 syntax with the benefit of static typing. Then on top of that templating language we could create Domain Specific Languages (let's say HTML4, XHTML, HTML5, RSS, Atom, Multipart Emails and so on). One of the best DSLs in .NET 4 (if not only one) is SharpDOM. It implements HTML-specific DSL. Looking at SharpDOM, I am really impressed of what you can do using .NET (4). So I believe there are some not-so-well-known ways for implementing custom DSLs in .NET 4. Possibly not as well as in Ruby, but still. So my the question would be: what are the C# (4) specific syntax features that can be used for implementing custom DSLs? Examples I can think of right now: // HTML - doesn't look tooo readable :) div(clas: "head", ul(clas: "menu", id: "main-menu", () => { foreach(var item in allItems) { li(item.Name) } }) // See how much noise it has with all the closing brackets? ) // Plain text (Email or something) - probably too simple Line("Dear {0}", user.Name); Line("You have been kicked off from this site"); For me it is really hard to come up with the syntax with least amount of noise. Please NOTE that I am not talking about another language (Boo, IronRuby etc), neither I am not talking about different templating engines (NHaml, Spark, StringTemplate etc). Thanks, Dmitriy.

  • Programmatically call webmethods in C#

    - by hancock
    I'm trying to write a function that can call a webmethod from a webserive given the method's name and URL of the webservice. I've found some code on a blog that does this just fine except for one detail. It requires that the request XML be provided as well. The goal here is to get the request XML template from the webservice itself. I'm sure this is possible somehow because I can see both the request and response XML templates if I access a webservice's URL in my browser. This is the code which calls the webmethod programmatically: XmlDocument doc = new XmlDocument(); //this is the problem. I need to get this automatically doc.Load("../../request.xml"); HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost/dummyws/dummyws.asmx?op=HelloWorld"); req.ContentType = "text/xml;charset=\"utf-8\""; req.Accept = "text/xml"; req.Method = "POST"; Stream stm = req.GetRequestStream(); doc.Save(stm); stm.Close(); WebResponse resp = req.GetResponse(); stm = resp.GetResponseStream(); StreamReader r = new StreamReader(stm); Console.WriteLine(r.ReadToEnd());

  • TinyMCE + jQuery + custom plugin = tinymce is undefined?

FireBug says that tinymce() in undefined; this message occurs in each() loop. Thus, tinymce() is actually initialized. I am really lost towards, what could be causing this.

  • iPhone: Utility Application - Open Flipside on startup

    - by Joel
    I have an application that I started with the Utility Application template. I'm using the Flipside for the Settings screen. I'm having the settings serialized to a file when the app is closed and deserialized when the app is opened. If there is no file to deserialize at startup, I want the flipside to be shown so the user can enter required information. This is what I have: - (void)viewDidLoad { flipController = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; flipController.delegate = self; flipController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; if(![self deserialize]) { [self showInfo]; } } - (IBAction)showInfo { [self presentModalViewController:flipController animated:YES]; } showInfo is the method that is called with the little 'i' button is pressed on the MainView. The button works, however my call in viewDidLoad doesn't. I have run through my code with the debugger. [self deserialize] is returning NO and [self showInfo] is being called, and I checked if flipController is nil in that context, and it's not. I've searched around and couldn't find anyone who's tried to do the same thing. I'm stumped to as why this isn't working. Anyone see what I'm doing wrong? Thanks

  • Annotation to make available generic type

    - by mdma
    Given an generic interface like interface DomainObjectDAO<T> { T newInstance(); add(T t); remove(T t); T findById(int id); // etc... } I'd like to create a subinterface that specifies the type parameter: interface CustomerDAO extends DomainObjectDAO<Customer> { // customer-specific queries - incidental. } The implementation needs to know the actual template parameter type, but of course type erasure means isn't available at runtime. Is there some annotation that I could include to declare the interface type? Something like @GenericParameter(Customer.class) interface CustomerDAO extends DomainObjectDAO<Customer> { } The implementation could then fetch this annotation from the interface and use it as a substitute for runtime generic type access. Some background: This interface is implemented using JDK dynamic proxies as outlined here. The non-generic version of this interface has been working well, but it would be nicer to use generics and not have to create a subinterface for each domain object type. The actual type is needed at runtime to implement the newInstance method, amongst others.

  • how to handle base tag target attribute in iphone uiwebview to open new window

    - by user217428
    When the links are supposed to open a new window, iphone uiwebview won't trigger an event when user click these links. We had to use javascript to do some trick to the target attribute of the links. I can handle 'a' tag to open in the '_self' window with the trick without problem. But when I do it the same way with the 'base' tag. it doesn't work. I believe the base target is set by the javascript. But the base tag is in the head, which may be handled by the uiwebview before my javascript executed, so the target change may not reflected in the webkit engine. Could someone please give some suggestion, so I can open the link in the same uiwebview? The following is the sample HTML opened in the uiwebview <html> <head> <base target='_blank'> </head> <body> <a href='http://google.ca'>google</a> </body> </html> The following is the code to be executed in the (void) webViewDidFinishLoad: (UIWebView*)webView static NSString* js = @"" "function bkModifyBaseTargets()" "{" "var allBases = window.document.getElementsByTagName('base');" "if (allBases)" "{" "for (var i = 0; i < allBases.length; i++)" "{" "base = allBases[i];" "target = base.getAttribute('target');" "if (target)" "{" "base.setAttribute('target', '_self');" "}" "}" "}" "}"; [webView stringByEvaluatingJavaScriptFromString: js]; [webView stringByEvaluatingJavaScriptFromString: @"bkModifyBaseTargets()"];

This enables animation, styling, binding, etc... public static readonly DependencyProperty SelectableProperty = DependencyProperty.RegisterAttached("Selectable", typeof(bool), typeof(Label), new UIPropertyMetadata(false)); } And then I'm trying to create a style with a trigger that depends on it: <!--Label--> <Style TargetType="{x:Type Label}"> <Style.Triggers> <Trigger Property="Util:LabelExtension.Selectable" Value="True"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Label}"> <TextBox IsReadOnly="True" Text="{TemplateBinding Content}" /> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> But I'm getting a run time exception: Cannot convert the value in attribute 'Property' to object of type 'System.Windows.DependencyProperty'. Error at object 'System.Windows.Trigger' in markup file How can I access the value of the attached property in a style trigger? I have tried using a DataTrigger with a RelativeSource binding but it wasn't pulling the value through.

  • Treebeard admin in Django

    - by Sharath
    I've setup Treebeard in Django and everything seems to have gone well. I tried to setup the admin system and I can see my models being presented in the admin interface. However, when I try to add new data using the admin interface, I get the following error in my template. The code still works fine, and I did a check in my DB and the data seems to be inserted properly. However, the view doesn't seem to load properly. Any idea about what is causing this?? The exception am getting is.. Caught an exception while rendering: Failed lookup for key [request] in u'[{\'action_index\': 0, \'block\': , , , , , , ]}, {\'block\': , , , ], , , , , \n \', ], , ], , , , ], , , \n \', , , , , , , , , ], , ], \n \']}, {\'cl\': , \'root_path\': None, \'actions_on_bottom\': False, \'title\': u\'Select album to change\', \'has_add_permission\': True, \'media\': , \'is_popup\': False, \'action_form\': , \'actions_on_top\': True, \'app_label\': \'gallery\'}, {\'MEDIA_URL\': \'\'}, {\'LANGUAGES\': ((\'ar\', \'Arabic\'), (\'bn\', \'Bengali\'), (\'bg\', \'Bulgarian\'), (\'ca\', \'Catalan\'), (\'cs\', \'Czech\'), (\'cy\', \'Welsh\'), (\'da\', \'Danish\'), (\'de\', \'German\'), (\'el\', \'Greek\'), (\'en\', \'English\'), (\'es\', \'Spanish\'), (\'et\', \'Estonian\'), (\'es-ar\', \'Argentinean Spanish\'), (\'eu\', \'Basque\'), (\'fa\', \'Persian\'), (\'fi\', \'Finnish\'), (\'fr\', \'French\'), (\'ga\', \'Irish\'), (\'gl\', \'Galician\'), (\'hu\', \'Hungarian\'), (\'he\', \'Hebrew\'), (\'hi\', \'Hindi\'), (\'hr\', \'Croatian\'), (\'is\', \'Icelandic\'), (\'it\', \'Italian\'), (\'ja\', \'Japanese\'), (\'ka\', \'Georgian\'), (\'ko\', \'Korean\'), (\'km\', \'Khmer\'), (\'kn\', \'Kannada\'), (\'lv\', \'Latvian\'), (\'lt\', \'Lithuanian\'), (\'mk\', \'Macedonian\'), (\'nl\', \'Dutch\'), (\'no\', \'Norwegian\'), (\'pl\', \'Polish\'), (\'pt\', \'Portuguese\'), (\'pt-br\', \'Brazilian Portuguese\'), (\'ro\', \'Romanian\'), (\'ru\', \'Russian\'), (\'sk\', \'Slovak\'), (\'sl\', \'Slovenian\'), (\'sr\', \'Serbian\'), (\'sv\', \'Swedish\'), (\'ta\', \'Tamil\'), (\'te\', \'Telugu\'), (\'th\', \'Thai\'), (\'tr\', \'Turkish\'), (\'uk\', \'Ukrainian\'), (\'zh-cn\', \'Simplified Chinese\'), (\'zh-tw\', \'Traditional Chinese\')), \'LANGUAGE_BIDI\': False, \'LANGUAGE_CODE\': \'en-us\'}, {}, {\'perms\': , \'messages\': [], \'user\': }, {}]' This happens after I hit the save button in Django admin.

  • ACL actions tag cause 'roles resource tree' draw incorrectly in admin/system/permissions/roles

    - by latvian
    Hi, We created new action similar to 'hold', 'ship' and others in the 'sales_order/view' admin section that can be triggered by clicking at the button. Afterward, we added our new action to the ACL with the following code in config.xml: <acl> <resources> <admin> <children> <sales> <children> <order> <children> <actions translate="title"> <title>Actions</title> <children> <shipNew translate="title"><title>Ship Ups</title></shipNew> </children> </actions> </children> <sort_order>10</sort_order> </order> </children> </sales> </children> </admin> </resources> </acl> ACL functionality works, however, in the 'Resources Tree'(System/Permissions/Roles/Role Resources) our new action does never show up as selected(checked) even thou it is allowed for particular Role. I can see that from table 'admin_rule' with resource id for our new action that it is allowed, so it needs to be selected, but it is not. When trying to solve this issue i looked into the template(permissions/rolesedit.phtml) and I found that the 'resource tree' is draw with Javascript...thats where i got stock due to my limited knowledge in Javascript. Why the resource tree does not display our new ACL entry correctly, that is the check box is never checked? Thank You for helping margots

  • Selecting a Java framework for large application w/ only ONE user

    - by Bijan
    I am building a large application that will be hosted on an AWS server. I'm trying to select a web framework for assisting me with code organization, template design, and generally presentation aspects. Here are some points of consideration: Require security/login/user authentication. I may add the ability in the future to allow more than just an administrator to access the web app, but it is not a public facing website. AJAX support would be helpful. There are a couple widgets that I don't want to recreate. One is a tree object, where the user can expand/contract items in the list, can create new branches, add/edit objects. This would be better off in some dynamic view rather than all done in ugly html. Generally, this is just to provide the application with a face for control, management, and monitoring. Having an easier time adding buttons, CSS, AJAX widgets are great additions though, but not the primary purpose. I'm considering: Wicket Spring Seam GWT Stripe and the list goes on, as I'm sure you all know. I originally planned on using GWT, but then started to feel that GWT didn't cover my primary needs. I could be wrong about this, but there seems to be a lot of support for GWT AND Wicket/Spring. All of this 'getting lost in java frameworks' got me thinking outside the java realm for a framework that would suit my needs that was a clear option, like: JRuby/Rails Jython/Django Groovy/Grails Guice (just throwing this in there... I don't clearly understand the main purposes of all these frameworks. It doesn't seem like DInjection is something I need for a single purpose application) Thanks as always. This community makes Googling for esoteric programming information an order of magnitude better.

  • SQL 2005 indexed queries slower than unindexed queries

    - by uos??
    Adding a seemingly perfectly index is having an unexpectedly adverse affect on a query performance... -- [Data] has a predictable structure and a simple clustered index of the primary key: ALTER TABLE [dbo].[Data] ADD PRIMARY KEY CLUSTERED ( [ID] ) -- My query, joins on itself looking for a certain kind of "overlapping" records SELECT DISTINCT [Data].ID AS [ID] FROM dbo.[Data] AS [Data] JOIN dbo.[Data] AS [Compared] ON [Data].[A] = [Compared].[A] AND [Data].[B] = [Compared].[B] AND [Data].[C] = [Compared].[C] AND ([Data].[D] = [Compared].[D] OR [Data].[E] = [Compared].[E]) AND [Data].[F] <> [Compared].[F] WHERE 1=1 AND [Data].[A] = @A AND @CS <= [Data].[C] AND [Data].[C] < @CE -- Between a range [Data] has about a quarter-million records so far, 10% to 50% of the data satisfies the where clause depending on @A, @CS, and @CE. As is, the query takes 1 second to return about 300 rows when querying 10%, and 30 seconds to return 3000 rows when querying 50% of the data. Curiously, the estimated/actual execution plan indicates two parallel Clustered Index Scans, but the clustered index is only of the ID, which isn't part of the conditions of the query, only the output. ?? If I add this hand-crafted [IDX_A_B_C_D_E_F] index which I fully expected to improve performance, the query slows down by a factor of 8 (8 seconds for 10% & 4 minutes for 50%). The estimated/actual execution plans show an Index Seek, which seems like the right thing to be doing, but why so slow?? CREATE UNIQUE INDEX [IDX_A_B_C_D_E_F] ON [dbo].[Data] ([A], [B], [C], [D], [E], [F]) INCLUDE ([ID], [X], [Y], [Z]); The Data Engine Tuning wizard suggests a similar index with no noticeable difference in performance from this one. Moving AND [Data].[F] <> [Compared].[F] from the join condition to the where clause makes no difference in performance. I need these and other indexes for other queries. I'm sure I could hint that the query should refer to the Clustered Index, since that's currently winning - but we all know it is not as optimized as it could be, and without a proper index, I can expect the performance will get much worse with additional data. What gives?
