, I want to use fluent hibernate with asp.net but couldn't find any website or tutorial for that , they're all to configure it with asp.net mvc , anyone knows any?
I have a session criteria statement (Fluent NHibernate) that does not seem to filter the child collection even though I have Expressions/Restrictions defined.
This returns all the objects of type MyClass that have MyCollection.Property = value, however MyCollection is not filtered to MyCollection.Property = value
We are developing a multi-language web application with ASP.NET MVC 2 and Fluent NHibernate.Our platform will be multi-language. But just static text will be multi-language. Groups pages depends on community content whatever they use. Like Facebook.We decide to keep all language string in database. And load language when application starts.
I have the following models & mappings (code snippets further below).
One Competition has to have multiple CompetitionAnswers associated with it (multiple choice) from the outset.
At present, using the Fluent NHibernate mappings shown below, when I create a brand new Competition object, populate the properties, then create 3 brand new CompetitionAnswer objects and add them to the CompetitionAnswers property (property on Competition), I would expect to call Save on the session which would INSERT the 1 Competition row and 3 CompetitionAnswer rows to the DB.
However, as soon as I try to call Save on the session, it complains that CompetitionId is null and it can't insert a null into the CompetitionAnswers table for that field - which is right, it shouldn't, however, I assumed that the NHibernate would first create the Competition, then use the newly generated IDENTITY value (CompetitionId) in the CompetitionAnswers table?
I've upgraded an ASP.Net Web application to the latest build of Fluent NHibernate (1.0.0.636) and the newest version of NHibernate (v2.1.2.4000). I've checked a couple of times that the application is running in Full trust. But I keep getting the following error:
Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Anyone had a similar error? I've seach the web / stackoverflow / NHibernate forums but only found people who had a problem when running in medium trust mode, not full trust. I've been developing for several months on this application on this machine with previous versions of Fluent NHibernate and NHibernate.
The machine I'm running this on is 64-bit, you never know that this is relevant.
I am using the above combo in a new web app Im doing just to try to learn to build new stuff to expand my knowledge. Im hoping to go live if I do a good job.. Im kind of new at MVC and the other products so I was trying to find a link to a good tutorial that set all of these up together.
I'm working on a RoleProvider in .NET, using Fluent NHibernate to map tables in an Oracle 9.2 database.
The problem is that the many-to-many table connecting users and roles uses a primary key generated from a sequence, as opposed to a composite key. I can't really change this, because I'm writing it to be implemented in a larger existing system.
Here is my UserMap:
public UserMap() { this.Table("USR");[code].....
Yet, this is giving me the error:
Type 'FluentNHibernate.Cfg.FluentConfigurationException' in assembly 'FluentNHibernate, Version=1.0.0.593, Culture=neutral, PublicKeyToken=8aa435e3cb308880' is not marked as serializable.
Is there a simple fix to allow this HasMayToMany to use my PersistentObjectMap extension? I'm thinking I may have to add a convention for this many-to-many relationship, but I don't know where to start with that, since I've just started using NHibernate and Fluent NHibernate only recently.
EDIT: I think I've found a possible solution here: http://marekblotny.blogspot.com/2009/02/fluent-nhbernate-and-collections.html
I'll try the above method of creating an entity and a class map for the linking table and post my findings.
EDIT 2: I created a linking entity as mentioned in the above blog post and downloaded the newest binaries (1.0.0.623). This helped me discover that the issue was with setting lazy load and trying to add roles to the user object in a completely new session.
I modified the code to move OpenSession to the BeginRequest of an HttpModule as described here. After doing this, I changed my data access code from wrapping the open session in a using statement, which closes the session when it is finished, to getting the current session and wrapping only the transaction in a using statement.
This seems to have resolved the bulk of my issue, but I am now getting an error that says "Could not insert collection" into the USR_ROLE table. And I'm wondering if the above code should work with a UserRoleMap described as:
public UserRoleMap() { this.Table("USR_ROLE"); [code]....
Hibernate's documentation for many-to-many relationship suggests creating an object to maintain a one-to-many/many-to-one, as in an ERD. I'm sure this would be much easier with conventional naming standards, but I have to stick with certain abbreviations and odd (and not always properly-implemented) conventions.
am trying to implement fluent nhibernate in MVC project...there were no build errors... but when i run the project i get this exception
System.Xml.Schema.XmlSchemaValidationException: The element 'class' in namespace 'urn:nhibernate-mapping-2.2' has incomplete content. List of possible elements expected: 'meta, subselect, cache, synchronize, comment, tuplizer, id, composite-id' in namespace 'urn:nhibernate-mapping-2.2'.
have no idea what am doing wrong here... the following is the code for opening session factory...
I'm using Nhibernate as the OR/M tool for an asp.net application and the startup performance is really frustrating. Part of the problem is definitely me in my lack of understanding but I've tried a fair bit (understanding is definitely improving) and am still getting nowhere.
Currently ANTS profiler has that the Configure() takes 13-18 seconds and the BuildSessionFActory() as taking about 5 seconds. From what i've read, these times might actually be pretty good, but they were generally talking about hundreds upon hundreds of mapped entities...this project only has 10.
I've combined all the mapping files into a single hbm mapping file and this did improve things but only down to the times mentioned above...
I guess, are there any "Traps for young players" that are regularly missed...obvious "I did this/have you enabled that/exclude file x/mark file y as z" etc...
I'll try the serialize the configuration thing to avoid the Configure() stage, but I feel that part shouldn't be that long for that amount of entities and so would essentially be hiding a current problem...
I've been trying to follow the directions on the NHProf site but can't seem to make it work. What am I missing?I put a log4net configuration section in my web.config:
How can I see debug/trace type info for the MVC layer. This would be things like see the incoming HTTP requests, which routes they are mapped again, the incoming parameters etc.
(i.e. same kind of info I see when I am working on a Ruby on Rails app for it's MVC infrastructure)
I am writing unit tests for fluent Nhibernate, when I run the test in isloation it passes, but when I run multiple tests. or run the test more than once it starts failing with the message below System.ApplicationException : For property 'Id' expected '1' of type 'System.Int32' but got '2' of type 'System.Int32'
I am trying to redirect my trace output to a text file.
For this I tried to add a textwritertracelistener object to Trace.Listeners.Add but I can't see Listeners Class in Trace.ie When I put Trace. the Listeners class is not popup. Also I am unable to add System.Diagnostics.TraceListener namespace to the page.
I want to debug EditPanel.debug.js file of HTML Editor, but it never shows in VS 08 and Im sure it executes to that line.What I did to enable debuggingUnchecked both 2 checkboxes for disabling the debugging
Set ScriptMode="Debug"
Change following line
[ClientScriptResource("AjaxControlToolkit.HTMLEditor.EditPanel", "AjaxControlToolkit.HTMLEditor.EditPanel.js")] to [ClientScriptResource("AjaxControlToolkit.HTMLEditor.EditPanel", "AjaxControlToolkit.HTMLEditor.EditPanel.debug.js")]
Debug-Start Debugging/Debug-StartWithoutDebugging OR Project ASP.Net Configuration launches Dreamweaver. It started lastnight, I had both Deamweaver and VWD 2008 express open at the same time - (I was looking at JQuery in the Microsoft and Dreamweaver enviroments simultaniously). After the first tie this happened, I closed down Dreamweaver (CS3) and it opened when I tried to run my VWD project. I reinstalled VWD 2008 express, IIS and disabled Dreamweaver (renamed the exe). Dreamweaver still came up.
