c# - Does saving to context in MVC update object attributes? -

-

I was wondering if it always happens that ASP saves an object in an MVC to an object with DB?

Just ask for example that I have a student class with field ID and where is the name

the key to the records is clearly ID

If I have a student: student student = new student ("student name");

and do 

  context. Insert (student); Id will be assigned a number reference. Save ();   
 After such operation, it is assumed that the "student" ID has been updated? Or do I have to ask it to the database.  
 Thanks   
 
 
 OK. .. depends on! :) You are describing a case where EF conferences are doing something for you. Code First Conference looks for those areas which have been named ID or [class name] ID and it determines that The keys are for the classes. You class design just match this conference. Because you have ID property integer type, EF has also configured it to be the identity column in the database. Therefore, when you save your object, it creates your database ID and the reference is partially updated.  
 Regarding documentation, Julia Lerman wants about three EF books.

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
