c# - Fluent NHibernate Mapping - Saving Child object -

-

I have a problem with selfish NHibernate mapping, I think, mapping to avoid any problems.

I have a business object (literally, a "business"), and the review object can be several reviews in every business that are created on a page in the UI. Business review is a property, as follows: 

  Public Class Business {Public Virtual Ink BusinessId {get; Set;} Public Virtual DateTime LastModified {get; Set;} Public Virtual ILIT & lt; Review & gt; Review {get; Set;} [More to be summarized further ...] Public Sector Review {Public Virtual Ink Review ID {Set; Set;} public virtual string review text {received; Set;} public virtual business business {receive; Set;} [... more for brevity has been removed ...]

My mapping are as follows: 

  Public category reviewmap: Classplop & lt; Review & gt; {Public ReviewMap () (Together ("Reviews"); ID (x => x.ReviewId). CallmanName ("Review ID") generated. Identification (); Context (x = & gt; x (Business name); map (x => x review text); [... and so on ...]} Public class businessmap: classmap  gt; { Public BusinessMap (with Affordable ("Business"); ID (x => x.BusinessId). CallName IS ("Business Id") generated. ID (); Map (x = & x; x.Name) Column name IS (" Business Name "); Map (x => X.LastModified," LastModifiedOn "); HasMany & lt; review & gt; (x = & gt; X. review). Inverted (); For lazy (); More deleted ...]}

repository code 

  using Public Zero Save (T Entity) {eSession session = GetSession () ) In the code (ITRansaction tx = session.BeginTransaction ()) {session.SaveOrUpdate (unit); tx.Commit ();}}

In the code, I type the property to the review object Allot, and call the repository service method.

The problem is that since I am not updating the business, I hope that he will save - the review that I want is reviewed. But the code also tries to save the business, and I am getting a surprise, because I have not set the "last modified" property - nor do I want to, because I am saving the review, not the business.

How do I establish a mapping to allow it to happen?

This issue may be coming for business and review to require fireworks.

Can you include the mapping of your business object if it does not help?

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
