• How do I map to a parent or child in the same table with NHibernate?

  - by adolfojp

  Lets suppose that I have a Category table with a column that holds the id of a parent or child category from the same table. This design would allow me to have unlimited levels of Categories, or unlimited levels in a thread, for example. How can I map this relationship with NHibernate? Are there any disadvantages or warnings that I should take into consideration when doing this?

• Delphi Search Edit Component

  - by Reber

  Hi, I need a delphi component for Delphi 2007 win32 that have features like Google search text box. ** While User writing search key it should fill/refresh the list with values, and user can select one of them. **User can go up and down list and can select one of them. **List should contain codes and text pair, so user can select text and I can get code for database operations. (Google can highlight the search text in List but I think it is not possible with Delphi 2007, so it is not excepted.) I tried Dev Express TcxMRUEdit, however it doesn't meet my needs

• Google Search API - Only returning 4 results

  - by user353829

  After much experimenting and googling, the following Python code successfully calls Google's Search APi - but only returns 4 results: after reading the Google Search API docs, I thought the 'start=' would return additional results: but this not happen. Can anyone give pointers? Thanks. Python code: /usr/bin/python import urllib import simplejson query = urllib.urlencode({'q' : 'site:example.com'}) url = 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&%s&start=50' \ % (query) search_results = urllib.urlopen(url) json = simplejson.loads(search_results.read()) results = json['responseData']['results'] for i in results: print i['title'] + ": " + i['url']

• Entity Framework vs. nHibernate for Performance, Learning Curve overall features

  - by hadi

  I know this has been asked several times and I have read all the posts as well but they all are very old. And considering there have been advancements in versions and releases, I am hoping there might be fresh views. We are building a new application on ASP.NET MVC and need to finalize on an ORM tool. We have never used ORM before and have pretty much boiled down to two - nHibernate & Entity Framework. I really need some advice from someone who has used both these tools and can recommend based on experience. There are three points that I am focusing on to finalize - Performance Learning Curve Overall Capability Your advice will be highly appreciated. Best Regards,

• Using Fluent NHibernate in commercial application

  - by Paja

  I want to use Fluent NHibernate in commercial desktop application, and I'm little concerned about the licensing. I've downloaded Fluent NHibernate precompiled binaries, and it contains this list of files: Antlr3.Runtime.dll Castle.Core.dll Castle.DynamicProxy2.dll FluentNHibernate.dll Iesi.Collections.dll log4net.dll NHibernate.dll NHibernate.ByteCode.Castle.dll I guess I will have to add all of these files to my Inno Setup script, which will install them on user's computer. But what should I do to comply to all of the licenses associated with each file? I'm sure I'm not the first who wants to use Fluent NHibernate in commercial application, so I hope I won't have to study each of the licenses. I'm not a lawyer.

• SQL Injection with Plain-Vanilla NHibernate

  - by James D

  Hello, Plain-vanilla NHibernate setup, eg, no fluent NHibernate, no HQL, nothing except domain objects and NHibernate mapping files. I load objects via: _lightSabers = session.CreateCriteria(typeof(LightSaber)).List<LightSaber>(); I apply raw user input directly to one property on the "LightSaber" class: myLightSaber.NameTag = "Raw malicious text from user"; I then save the LightSaber: session.SaveOrUpdate(myLightSaber); Everything I've seen says that yes, under this situation you are immune to SQL injection, because of the way NHibernate parameterizes and escapes the queries under the hood. However, I'm also a relative NHibernate beginner so I wanted to double-check. *waves hand* these aren't the droids you're looking for. Thanks!

• Can Fluent nhibernate's automapper be configured to handle private readonly backing fields?

  - by Mark Rogers

  I like private readonly backing fields because some objects are mostly read-only after creation, and for collections, which rarely need to be set wholesale (instead using collection methods to modify the collection). For example: public class BuildingType : DomainEntity { /* rest of class */ public IEnumerable<ActionType> ActionsGranted { get { return _actionsGranted; } } private readonly IList<ActionType> _actionsGranted = new List<ActionType>(); private readonly Image _buildingTile; public virtual Image BuildingTile { get { return _buildingTile; } } } But as far as I remember fluent-nhibernate's automapper never had a solution for private readonly backing fields, I'm wondering if that's changed in the last few months. So here's my question: How do I configure automapper or create an automapping convention to map private readonly backing fields?

• Getting Started with Fluent NHibernate

  - by Andy

  I'm trying to get into using Fluent NHibernate, and I have a couple questions. I'm finding the documentation to be lacking. I understand that Fluent NHibernate / NHibernate allows you to auto-generate a database schema. Do people usually only do this for Test/Dev databases? Or is that OK to do for a production database? If it's ok for production, how do you make sure that you're not blowing away production data every time you run your app? Once the database schema is already created, and you have production data, when new tables/columns/etc. need to be added to the Test and/or Production database, do people allow NHibernate to do this, or should this be done manually? Is there any REALLY GOOD documentation on Fluent NHibernate? (Please don't point me to the wiki because in following along with the "Your first project" code building it myself, I was getting run-time errors because they forget to tell you to add a reference. Not cool.) Thanks, Andy

• How do I add multiple joins (Fetches) to a joined table using nhibernate and LINQ ?

  - by ooo

  i have these tables /entities VacationRequestDate table which has a VacationRequestId field that links with VacationRequest table VacationRequest has PersonId and RequestStatusId fields that links with Person and RequestStatus respectively. i have this query so far: IEnumerable<VacationRequestDate> dates = Session.Query<VacationRequestDate>().Fetch(r => r.VacationRequest).ThenFetch(p=>p.RequestStatus).ToList(); this works fine and joins with VacationRequest and then VacationRequest joins with RequestStatus but i can't figure out how to add an additional EAGER join to the VacationRequest table. If i add a Fetch at the end, it refers to the VacationRequestDate table If i add a ThenFetch at the end, it refers to the RequestStatus table I can't find any api that will refer to the VacationRequest table as the reference point. how would you add multiple joins to a joined table using nhibernate LINQ ?

• How to look up an NHibernate entity's table mapping from the type of the entity?

  - by snicker

  Once I've mapped my domain in NHibernate, how can I reverse lookup those mappings somewhere else in my code? Example: The entity Pony is mapped to a table named "AAZF1203" for some reason. (Stupid legacy database table names!) I want to find out that table name from the NH mappings using only the typeof(Pony) because I have to write a query elsewhere. How can I make the following test pass? private const string LegacyPonyTableName = "AAZF1203"; [Test] public void MakeSureThatThePonyEntityIsMappedToCorrectTable() { string ponyTable = GetNHibernateTableMappingFor(typeof(Pony)); Assert.AreEqual(LegacyPonyTableName, ponyTable); } In other words, what does the GetNHibernateTableMappingFor(Type t) need to look like?

• How to Switch Chrome’s Default Search to International Google

  - by Erez Zukerman

  Google Chrome’s default search engine is Google. This makes perfect sense; the only problem is that it uses localized Google – for example, Google France or Google Israel. This impacts the interface language, and sometimes even the text orientation. Here’s how you can fix this and get “international” Google results with an English interface. First, we need to figure out what search query we’re going to use. Go to Google.com and execute a simple query for a single word – say “cats”. If you get real-time results, hit Enter so that the address bar updates with the query URL. It should look something like this: http://www.google.com/#sclient=psy&hl=en&site=&source=hp&q=cats&aq=f&aqi=g1g-s1g3&aql=&oq=&pbx=1&bav=on.2,or.&fp=369c8973645261b8 If you wish to customize your search further, click Advanced Search. For example, I would like Google to annotate results with the reading level they require, so I can see what’s going to be difficult to read: Latest Features How-To Geek ETC Macs Don’t Make You Creative!

• Is there an alternative to Google Code Search?

  - by blunders

  Per the Official Google Blog: Code Search, which was designed to help people search for open source code all over the web, will be shut down along with the Code Search API on January 15, 2012. Google Code Search is now gone, and since that makes it much harder to understand the features it presented, here's my attempt to render them via information I gathered from a cache of the page for the Search Options: The "In Search Box" just notes the syntax to type the command directly in the main search box instead of using the advance search interface. Package (In Search Box: "package:linux-2.6") Language (In Search Box: "lang:c++") (OPTIONS: any language, actionscript, ada, applescript, asp, assembly, autoconf, automake, awk, basic, bat, c, c#, c++, caja, cobol, coldfusion, configure, css, d, eiffel, erlang, fortran, go, haskell, inform, java, java, javascript, jsp, lex, limbo, lisp, lolcode, lua, m4, makefile, maple, mathematica, matlab, messagecatalog, modula2, modula3, objectivec, ocaml, pascal, perl, php, pod, prolog, proto, python, python, r, rebol, ruby, sas, scheme, scilab, sgml, shell, smalltalk, sml, sql, svg, tcl, tex, texinfo, troff, verilog, vhdl, vim, xslt, xul, yacc) File (In Search Box: "file:^.*.java$") Class (In Search Box: "class:HashMap") Function (In Search Box: "function:toString") License (In Search Box: "license:mozilla") (OPTIONS: null/any-license, aladdin/Aladdin-Public-License, artistic/Artistic-License, apache/Apache-License, apple/Apple-Public-Source-License, bsd/BSD-License, cpl/Common-Public-License, epl/Eclipse-Public-License, agpl/GNU-Affero-General-Public-License, gpl/GNU-General-Public-License, lgpl/GNU-Lesser-General-Public-License, disclaimer/Historical-Permission-Notice-and-Disclaimer, ibm/IBM-Public-License, lucent/Lucent-Public-License, mit/MIT-License, mozilla/Mozilla-Public-License, nasa/NASA-Open-Source-Agreement, python/Python-Software-Foundation-License, qpl/Q-Public-License, sleepycat/Sleepycat-License, zope/Zope-Public-License) Case Sensitive (In Search Box: "case:no") (OPTIONS: yes, no) Also of use in understanding the search tool would be the still live FAQs page for Google Code Search. Is there any code search engine that would fully replace Google Code Search's features?

• Multilingual sites and Google search results, using sub-folders for language

  - by AWinter

  About three months ago we added an English version of our, previously Japanese only, site under the subfolder /en/ we've tried to follow the sometimes incomplete best practices laid out by Google by adding alternate tags to all pages that are currently translated. The top page for instance has the following meta tags for language. <link rel="canonical" href="/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> While the English main page under /en/ has <link rel="canonical" href="/en/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> Alternate languages are setup in the sitemap. (as per Google's recommendations) It seems however that Google absolutely refuses to show the English top page in results when the user is using English at google.com if you search you'll, as of this post, get the Japanese description and a title that Google has apparently invented instead of the title and description in the meta-tags for the /en/ index page. Does anyone have any experience with subfolders actually working to affect search results? What are the best practices for ensuring that the correct language version of my website is displayed through Google and other search engines? And how long will it take before the new language version becomes prominent in search engine results?

• Can I use nofollow for offsite links without it affecting my page rank?

  - by Jack

  What I have is a page with almost all offsite links. Each clicked link is forwarded on to the destination. What I would like the search engines to do is to index the text between the anchor tag and not follow the link itself. <a href="somelink">Index This Text Only</a> I've read several articles and they all seem to contradict themselves as to when to use nofollow. What's been happening over the past 2 months that the site has been live is that both Google and Bing are crawling the site as well as all the links on the site that it has been forwarded to. The search engines are now generating a lot of 404s for images and files that never existed on my site but rather seems to correlate to the site it was forwarded to. The search engines don't seem to honor the 302 header when forwarded. I would like to get a definitive answer on the nofollow tag as it relates to my situation. Can I use nofollow to stop the 404s and if so, will it affect my page ranking negatively?
