I have a sample application that shows how to host Nancy on node.js.
To do that I need to change the rootpath. I ended up with something like that:
public class Startup
{
public static void Configuration(IAppBuilder app)
{
string rootpath = app.Properties["node.rootpath"] as string;
app.UseNancy(options => options.Bootstrapper = new NodeBootstrapper(rootpath));
}
}
public class NodeRootPathProvider : IRootPathProvider
{
private string rootpath;
public NodeRootPathProvider(string rootpath)
{
this.rootpath = rootpath;
}
public string GetRootPath()
{
return this.rootpath;
}
}
public class NodeBootstrapper : DefaultNancyBootstrapper
{
private string rootpath;
public NodeBootstrapper(string rootpath)
: base()
{
this.rootpath = rootpath;
}
protected override IRootPathProvider RootPathProvider
{
get { return new NodeRootPathProvider(this.rootpath); }
}
}
Is there a way to simplfy this?

I have a WPF app and I'm trying to use MEF to load viewmodels and view.
I can't successfully load Views.
The code:
public interface IContent
{
void OnNavigatedFrom( );
void OnNavigatedTo( );
}
public interface IContentMetadata
{
string ViewUri { get; }
}
[MetadataAttribute]
public class ExtensionMetadataAttribute : ExportAttribute
{
public string ViewUri { get; private set; }
public ExtensionMetadataAttribute(string uri) : base(typeof(IContentMetadata))
{
this.ViewUri = uri;
}
}
class ViewContentLoader
{
[ImportMany]
public IEnumerable<ExportFactory<IContent, IContentMetadata>> ViewExports
{
get;
set;
}
public object GetView(string uri)
{
// Get the factory for the View.
var viewMapping = ViewExports.FirstOrDefault(o =>
o.Metadata.ViewUri == uri);
if (viewMapping == null)
throw new InvalidOperationException(
String.Format("Unable to navigate to: {0}. " +
"Could not locate the View.",
uri));
var viewFactory = viewMapping.CreateExport();
var view = viewFactory.Value;
return viewFactory;
}
}
I supposed to use this code like this:
1)Decorate a User control
[Export(typeof(IContent))]
[ExtensionMetadata("CustomPause")]
[PartCreationPolicy(System.ComponentModel.Composition.CreationPolicy.NonShared)]
public partial class CustomPause : Page , IContent, IPartImportsSatisfiedNotification
{
public CustomPause()
{
InitializeComponent();
}
}
2) Compose the parts:
var cv = new CompositionContainer(aggregateCatalog);
var mef = new ViewContentLoader();
cv.ComposeParts(mef);
3) Load the view at runtime given a URI, for example:
private void CustomPause_Click(object sender, RoutedEventArgs e)
{
var vc = GlobalContainer.Instance.GetMefContainer() as ViewContentLoader;
MainWindow.MainFrame.Content = vc.GetView ("CustomPause");
}
Problem is this line in the GetView method fails:
var viewMapping = ViewExports.FirstOrDefault(o =>
o.Metadata.ViewUri == uri);
The query fails and so viewMapping is null but composition seems ok and I can see that ViewExports contains an object of type:
{System.ComponentModel.Composition.ExportFactory<EyesGuard.MEF.IContent, EyesGuard.MEF.IContentMetadata>[0]
I don't know where I'm wrong. Do you have a clue?

I had forgot this
[AttributeUsage(AttributeTargets.Class, AllowMultiple = false)]
in the MetadataAttribute
I'm upgrading my project from Nancy 1.4.5 -> 2.0
And I have errors:
public class AppBootstrapper : AutofacNancyBootstrapper
{
private readonly ILifetimeScope _scope;
public AppBootstrapper(ILifetimeScope scope)
{
_scope = scope;
}
protected override ILifetimeScope GetApplicationContainer()
{
return _scope;
}
protected override void ApplicationStartup(ILifetimeScope container, IPipelines pipelines)
{
JsonSettings.MaxJsonLength = int.MaxValue;
JsonSettings.RetainCasing = true;
base.ApplicationStartup(container, pipelines);
}
}
}
Error CS0103 The name 'JsonSettings' does not exist in the current context
How can I resolve this issue?
I added method to AppBootstrapper class:
public class AppBootstrapper : DefaultNancyBootstrapper
{
public override void Configure(INancyEnvironment environment)
{
environment.Json(retainCasing: true);
}
... other methods
}
And added maxJsonLength to web.config:
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="2147483647"/>
</webServices>
</scripting>
</system.web.extensions>
I have the following DbContext:
namespace Tasks.Models
{
public class TaskDBInitializer : DropCreateDatabaseIfModelChanges<TasksContext>
{
protected override void Seed(TasksContext context)
{
var projects = new List<Projects>
{
new Projects{ Title="proTitle", Describe="proDescribe" },
};
projects.ForEach(p => context.Projects.Add(p));
context.SaveChanges();
base.Seed(context);;
}
}
public class TasksContext : DbContext
{
public TasksContext() : base("name=TaskDB")
{
Database.SetInitializer(new TaskDBInitializer());
}
public DbSet<Task> Task { get; set; }
public DbSet<Projects> Projects { set; get; }
}
}
I now want to add another model but don't want to lose data that exists within the current database.
How can I add a model to my DbContext without losing data?
Instead of using DropCreateDatabaseIfModelChanges<TContext> as your IDatabaseInitializer<TContext> use MigrateDatabaseToLatestVersion<TContext,TMigrationsConfiguration> which will determine changes within your DbContext then update your existing database to be compatible.
Here is an example of how to implement the MigrateDatabaseToLatestVersion initializer:
namespace Tasks.Models
{
public sealed class TaskDBConfiguration : DbMigrationsConfiguration<TasksContext>
{
public TaskDBConfiguration()
{
AutomaticMigrationsEnabled = true;
AutomaticMigrationDataLossAllowed = false;
}
protected override void Seed(TasksContext context)
{
var projects = new List<Projects>
{
new Projects { Title = "proTitle", Describe = "proDescribe" },
};
projects.ForEach(p => context.Projects.Add(p));
context.SaveChanges();
base.Seed(context);
}
}
public class TasksContext : DbContext
{
public TasksContext() : base("name=TaskDB")
{
Database.SetInitializer<TasksContext>(
new MigrateDatabaseToLatestVersion<TasksContext, TaskDBConfiguration>()
);
}
public DbSet<Task> Task { get; set; }
public DbSet<Projects> Projects { set; get; }
}
}
I am trying to access a custom attribute applied to a method within a castle interceptor, but method Attribute.GetCustomAttribute() return null.
public class MyIntecept : Castle.DynamicProxy.IInterceptor
{
public void Intercept(IInvocation invocation)
{
// myAttr is null.
var myAttr = (MyAttribute)Attribute.GetCustomAttribute(
invocation.Method, typeof(MyAttribute));
}
}
[AttributeUsage(AttributeTargets.All, Inherited = true, AllowMultiple = true)]
public class MyAttribute : Attribute
{
readonly string _value;
public MyAttribute(string value)
{
this._value = value;
}
public string Value
{
get { return this._value; }
}
}
public interface IMyInterface
{
void Do();
}
public class MyClass : IMyInterface
{
[MyAttribute("MyValue")]
public void Do()
{
Console.WriteLine("Do");
}
}
How can i get 'MyAttribute'?
P.S. I'am using Castle.Core 3.3.3
Put the attribute "MyAttribute" on the method inside the interface and not inside the class
