  • Soft delete an entity in Grails with Hibernate Filters Plugin

    - by canotto90
    I was looking for a way to avoid deleting my users from DB, but instead to mark them as deleted and don't bring them back in queries. I found this plugin http://grails.org/plugin/hibernate-filter, which was a great tool for the task. But when I tried to implement my solution, I passed trought same problems whose solutions wheren't (or I was not able to find) on internet. So, next, I describe the way that I solve the problem of soft delete.

  • Validating XML using XSD with regex pattern

    - by Steel Plume
    Hello, I am parsing a XML file against a XSD containing some regex patterns used for checking input data, but only this regex generates an error, even if it passes into the Eclipse XSD plugin: InvalidRegex: Pattern value '(((com|it|org)\.)+(\b[a-z]+[.]{1}\b)+)?[A-Z]{1}[A-Za-z]+' is not a valid regular expression. The reported error was: 'This expression is not supported in the current option setting.'. So, with SAX validator where can I find the fatal "current option setting"?

  • IE6 "frame" layout with 100% height and scrollbars

    - by Joe
    I want to achieve a simple "frame" layout with fixed header, fixed left navigation area, and a main content area that fills 100% of the remainder of the viewport with scrollbars if necessary. My best attempt is below - but when I add enough content to the main div to force scrolling, I see that the scrollbar extends below the bottom of the viewport. What am I doing wrong? Or what is IE6 doing wrong and how can I fix it? NB please don't recommend using a more recent browser - I'd love to but can't. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title></title> <style type="text/css"> html, body { height:100%; margin:0; padding:0; overflow:hidden; } div { border:0; margin:0; padding:0; } div#top { background-color:#dddddd; height:100px; } div#left { background-color:#dddddd; float:left; width:120px; height:100%; overflow:hidden; } div#main { height:100%; overflow:auto; } </style> </head> <body> <div id="top">Title</div> <div id="left">LeftNav</div> <div id="main"> Content <p> Lorem ipsum ... </p> ... repeated several times ... </div> </body> </html>

  • Tutorials for .NET database app

    - by ChrisC
    My earlier question and comments are at "What is ADO.NET". This shows my level of knowledge about c# database apps. Can someone point me to tutorials and/or primers that can help me proceed from where I am (also stated in other question)? I've looked and all I've found are tutorials that talk about general db basics (ie, not helping with VS/C#), or talk about connecting to existing SQL db's. I need help setting one up and configuring it, as well as help on how to create and use queries to test the db schema.

  • Using a DataSet instead of custom business entities in soa and n-tier architecture

    - by kathy
    I’m working on a large and a high volume transactional enterprise application which has been designed using n-tire application architecture .And it was developed in the .NET platform utilizing C#,VB.NEt, Framework 3.5, ObjectDataSources, DataSet, WCF, asp.net update panel, JavaScript ,JSON, 3rd Party tools. The application is supposed to accomplish a really scalable / easily maintained / robust application / integrations, and to make sure that my services are created using a format that can be understood by other systems. The problem is, this application is about 70% complete but now I was wondering if the following would cause us future issues, I’m using a DataSet and a DataTable to (get /set) the data (form /to) the stored procedure in the database using the ObjectDataSources and was wondering if this would prevent my application from achieving the above goals. Actually, I am not anti-OO. I write lots of classes for different purposes, but I didn’t use the entity objects(custom business entities) instead of the previous way because I have a large database that may contain 50 tables and I was just afraid to create entities for each table and then in the future if I need to change the schema of the database, it might cause a huge affect on the application ?

  • spring jboss ehcache

    - by boyd4715
    I am trying to configure my application to make use of ehCache. I am using Spring 2.5.6, Jboss 5.1.0 GA and its embedded version of Hibernate along with ehCache-core V2.3.1. I have done the following configuration: <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.jdbc.batch_size">20</prop> <prop key="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</prop> <prop key="net.sf.ehcache.configurationResourceName">ehcache.xml</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.cache.use_structured_entries">true</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.generate_statistics">true</prop> <!-- prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</prop> <prop key="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.cache.use_query_cache">true</prop--> </props> </property> This is my ehcache.xml <defaultCache eternal="false" overflowToDisk="false" maxElementsInMemory="50000" timeToIdleSeconds="30" timeToLiveSeconds="6000" memoryStoreEvictionPolicy="LRU" /> <cache name="com.model.SystemProperty" maxElementsInMemory="5000" eternal="true" overflowToDisk="false" memoryStoreEvictionPolicy="LFU" /> This file is located in my class path. I have added the following to my domain object: @Cache(usage = CacheConcurrencyStrategy.READ_WRITE, region="vsg.ecotrak.admin.store.domain.Store", include="non-lazy") When I start up the server, it gets stuck. Here is the output: 13:17:09,000 INFO [SettingsFactory] Second-level cache: enabled 13:17:09,000 INFO [SettingsFactory] Query cache: enabled 13:17:09,016 INFO [SettingsFactory] Cache region factory : org.hibernate.cache.impl.bridge.RegionFactoryCacheProviderBridge 13:17:09,017 INFO [RegionFactoryCacheProviderBridge] Cache provider: net.sf.ehcache.hibernate.SingletonEhCacheProvider Any Ideal as to why this is happening? I am running on a Windows 7 64 bit if that matters. I downgraded the ehcache jar to V 1.2.3 and the server now starts.

  • How can two eclipse plugin use the same preferences store?

    - by St.Shadow
    I have two plugins, say com.site.plugin.core and com.site.plugin.ui. I'd like to separate core part from UI part, so at plugin com.site.plugin.ui I created Preferences page where I defined some preferences, which should be used by com.site.plugin.core. I check article at Eclipse site, but it is quite outdated, and linked bug also do not provide much info. So is it possible to do this using standard Eclipse mechanism, or I need use direct low-level API via package org.eclipse.core.runtime.preferences?

    Hi, so..I followed doctrine documnetation to get started. Here is the documentation http://www.doctrine-project.org/documentation/manual/1_2/en/working-with-models#dealing-with-relations:retrieving-related-records My code is $User = Doctrine_Core::getTable("User")->find(1); when I access relations by $User-Phonenumbers, it works. When I convert User object to array by using toArray() method, it does not convert relations to array. It simply display $User data. Am i missing something?

  • C# XPath Not Finding Anything

    - by ehdv
    I'm trying to use XPath to select the items which have a facet with Location values, but currently my attempts even to just select all items fail: The system happily reports that it found 0 items, then returns (instead the nodes should be processed by a foreach loop). I'd appreciate help either making my original query or just getting XPath to work at all. XML <?xml version="1.0" encoding="UTF-8" ?> <Collection Name="My Collection" SchemaVersion="1.0" xmlns="http://schemas.microsoft.com/collection/metadata/2009" xmlns:p="http://schemas.microsoft.com/livelabs/pivot/collection/2009" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <FacetCategories> <FacetCategory Name="Current Address" Type="Location"/> <FacetCategory Name="Previous Addresses" Type="Location" /> </FacetCategories> <Items> <Item Id="1" Name="John Doe"> <Facets> <Facet Name="Current Address"> <Location Value="101 America Rd, A Dorm Rm 000, Chapel Hill, NC 27514" /> </Facet> <Facet Name="Previous Addresses"> <Location Value="123 Anywhere Ln, Darien, CT 06820" /> <Location Value="000 Foobar Rd, Cary, NC 27519" /> </Facet> </Facets> </Item> </Items> </Collection> C# public void countItems(string fileName) { XmlDocument document = new XmlDocument(); document.Load(fileName); XmlNode root = document.DocumentElement; XmlNodeList xnl = root.SelectNodes("//Item"); Console.WriteLine(String.Format("Found {0} items" , xnl.Count)); } There's more to the method than this, but since this is all that gets run I'm assuming the problem lies here. Calling root.ChildNodes accurately returns FacetCategories and Items, so I am completely at a loss. Thanks for your help!

  • Tearing my hair out - ASP.Net AJAX AutoComplete not working

    - by Dave
    Hope someone can help with this. I've been up and down the web and through this site looking for an answer, but still can't get the Autocomplete AJAX control to work. I've gone from trying to include it in an existing site to stripping it right back to a very basic form and it's still not functioning. I'm having a little more luck using Page Methods rather than a local webservice, so here is my code <%@ Page Language="C#" AutoEventWireup="true" CodeFile="droptest.aspx.cs" Inherits="droptest" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:ScriptManager ID="ScriptManager1" EnablePageMethods="true" runat="server"> </asp:ScriptManager> <cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" MinimumPrefixLength="1" ServiceMethod="getResults" TargetControlID="TextBox1"> </cc1:AutoCompleteExtender> </form> </body> </html> using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.Script.Services; using System.Web.Services; public partial class droptest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } [WebMethod] public string[] getResults(string prefixText, int count) { string[] test = new string[5] { "One", "Two", "Three", "Four", "Five" }; return test; } } Tried to keep things as simple as possible, but all I get is either the autocomplete dropdown with the source of the page (starting with the <! doctype...) letter by letter, or in IE7 it just says "UNDEFINED" all the way down the list. I'm using Visual Web Developer 2008 at the moment, this is running on Localhost. I think I've exhausted all the "Try this..." options I can find, everything from adding in [ScriptMethod] to changing things in Web.Config. Is there anything obviously wrong with this code? Only other thing that may be having an effect is in Global.asax I do a Context.RewritePath to rewrite URLs - does this have any effect on AJAX? Thanks for any help you can give.

  • PostgreSQL Invalid Value for Parameter Warning

    - by gvkv
    In PostgreSQL 8.4.3, I get this error when logging on to one of my databases (adus): WARNING: invalid value for parameter "default_text_search_config": "tsc_markets" which makes sense since executing the command \dF does not list any such configuration (and only lists the defaults). However, when I ask psql to show me the current value: adus=# show default_text_search_config; I get default_text_search_config ---------------------------- pg_catalog.english (1 row) In addition, the postgresql.config file has the entry: # default configuration for text search default_text_search_config = 'pg_catalog.english' plus, there is only one (user) defined schema that I use (also called adus) in this database. What's going on?

  • C# Winforms ADO.NET - DataGridView INSERT starting with null data

    - by Geo Ego
    I have a C# Winforms app that is connecting to a SQL Server 2005 database. The form I am currently working on allows a user to enter a large amount of different types of data into various textboxes, comboboxes, and a DataGridView to insert into the database. It all represents one particular type of machine, and the data is spread out over about nine tables. The problem I have is that my DataGridView represents a type of data that may or may not be added to the database. Thus, when the DataGridView is created, it is empty and not databound, and so data cannot be entered. My question is, should I create the table with hard-coded field names representing the way that the data looks in the database, or is there a way to simply have the column names populate with no data so that the user can enter it if they like? I don't like the idea of hard-coding them in case there is a change in the database schema, but I'm not sure how else to deal with this problem.

  • Running CPython Applications With Visual Studio?

    I would like to know how to use Visual Studio with CPython (the official python.org python interpreter, not IronPython). In particular, I am interested in getting "build" and "run" commands in Visual Studio working. Other features such as color highlighting and auto-complete, I am less concerned about. Also, can the "build" command be made to run py2exe or similar exe packagers?

  • Prototype JS swallows errors in dom:loaded, and ajax callbacks?

    - by WishCow
    I can't figure out why prototype suppressess the error messages in the dom:loaded event, and in AJAX handlers. Given the following piece of HTML: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Conforming XHTML 1.1 Template</title> <script type="text/javascript" src="prototype.js"></script> <script type="text/javascript"> document.observe('dom:loaded', function() { console.log('domready'); console.log(idontexist); }); </script> </head> <body> </body> </html> The domready event fires, I see the log in the console, but there is no indication of any errors whatsoever. If you move the console.log(idontexist); line out of the handler, you get the idontexist is not defined error in the console. I find it a little weird, that in other event handlers, like 'click', you get the error message, it seems that it's only the dom:loaded that has this problem. The same goes for AJAX handlers: new Ajax.Request('/', { method: 'get', onComplete: function(r) { console.log('xhr complete'); alert(youwontseeme); } }); You won't see any errors. This is with prototype.js 1.6.1, and I can't find any indication of this behavior in the docs, nor a way to enable error reporting in these handlers. I have tried stepping through the code with FireBug's debugger, and it seems to jump to a function on line 53 named K, when it encounters the missing variable in the dom:loaded handler: K: function(x) { return x } But how? Why? When? I can't see any try/catch block there, how does the program flow end up there? I know that I can make the errors visible by packing my dom:ready handler(s) in try/catch blocks, but that's not a very comfortable option. Same goes for registering a global onException handler for the AJAX calls. Why does it even suppress the errors? Did someone encounter this before?

  • Django & google openid authentication (openid.ax) with socialauth

    - by Zayatzz
    Hello I am trying to use django-socialauth (http://github.com/uswaretech/Django-Socialauth) for authenticating users for my django project. This is firs time working with openid and i've had to figure out how exactly this open id works. I have more or less understood it, by now, but there are few things that elude me. The authentication process starts when the request is put together in in django-socialauth.openid_consumer.views.begin. I can see that the outgoing authentication request is more or less something like this: https://www.google.com/accounts/o8/ud?openid.assoc_handle=AOQobUckRThPUj3K1byG280Aze-dnfc9Iu6AEYaBwvHE11G0zy8kY8GZ& openid.ax.if_available=fname& openid.ax.mode=fetch_request& openid.ax.required=email& openid.ax.type.email=http://axschema.org/contact/email& openid.ax.type.fname=http://example.com/schema/fullname& openid.claimed_id=http://specs.openid.net/auth/2.0/identifier_select& openid.identity=http://specs.openid.net/auth/2.0/identifier_select& openid.mode=checkid_setup&openid.ns=http://specs.openid.net/auth/2.0& openid.ns.ax=http://openid.net/srv/ax/1.0& openid.ns.sreg=http://openid.net/extensions/sreg/1.1& openid.realm=http://localhost/& openid.return_to=http://localhost/social/gmail_login/complete/?janrain_nonce=2010-03-20T11%3A19%3A44ZPZCjNc&openid.sreg.optional=postcode,country,nickname,email This is lot like 2nd example here: http://code.google.com/apis/accounts/docs/OpenID.html#Samples The problem is, that the request, i get back, is nothing like the corresponding example from code.google.com (look at the 3rd example in example responses. Response dict i get is like this: { 'openid.op_endpoint': 'https://www.google.com/accounts/o8/ud', 'openid.sig': 'QWMa4x4ruMUvSCfLwKV6CZRuo0E=', 'openid.ext1.type.email': 'http://axschema.org/contact/email', 'openid.return_to': 'http://localhost/social/gmail_login/complete/?janrain_nonce=2010-03-20T17%3A54%3A06ZHV4cqh', 'janrain_nonce': '2010-03-20T17:54:06ZHV4cqh', 'openid.response_nonce': '2010-03-20T17:54:06ZdC5mMu9M_6O4pw', 'openid.claimed_id': 'https://www.google.com/accounts/o8/id?id=AItOghawkFz0aNzk91vaQWhD-DxRJo6sS09RwM3SE', 'openid.mode': 'id_res', 'openid.ns.ext1': 'http://openid.net/srv/ax/1.0', 'openid.signed': 'op_endpoint,claimed_id,identity,return_to,response_nonce,assoc_handle,ns.ext1,ext1.mode,ext1.type.email,ext1.value.email', 'openid.ext1.value.email': '[email protected]', 'openid.assoc_handle': 'AOQobUfssTJ2IxRlxrIvU4Xg8HHQKKTEuqwGxvwwuPR5rNvag0elGlYL', 'openid.ns': 'http://specs.openid.net/auth/2.0', 'openid.identity': 'https://www.google.com/accounts/o8/id?id=AItOawkghgfhf1FkvaQWhD-DxRJo6sS09RwMKjASE', 'openid.ext1.mode': 'fetch_response'} The socialauth itself has been built to accept my email address this way: elif request.openid and request.openid.ax: email = request.openid.ax.get('email') And obviously this fails. Why i am asking all this is, that perhaps i am doing something wrong and my outgoing request is wrong? Or am i doing all correctly and should change the socialaouth module to accept info in a new way and then commit the change? Alan
