Problem

confundido · March 18, 2009, 5:05pm

Hi all. I have a question that probably belongs on a users mailing list
but
I could not find one.
I get the following error when trying to use my IronRuby windsor
registration script:
System.InvalidOperationException: can’t convert
Castle::Core::ComponentModel into Castle::Core::ComponentModel

I assume this has something to do with the fact that newing up an object
in
IronRuby isn’t the same thing as newing it up in C#.

Any suggestions or guidance would be appreciated.

Here is the important IronRuby code:

require ‘Castle.Windsor’
require ‘Castle.MicroKernel’
require ‘Castle.Core’

ComponentRegistration =
Castle::MicroKernel::Registration::ComponentRegistration
ComponentModel = Castle::Core::ComponentModel
Parameter = Castle::MicroKernel::Registration::Parameter
Component = Castle::MicroKernel::Registration::Component

def component(options)
throw :classIsRequired if !options.has_key?(:class)
klass = options[:class].to_clr_type
if options.has_key?(:service)
service = options[:service].to_clr_type
else
service = klass
end
if options.has_key?(:name)
name = options[:name]
else
name = klass.class.name.underscore.lowercase
end
model = ComponentModel.new(name, service, klass)
if options.has_key?(:parameters)
parameters = options[:parameters]
parameters.each do |p|
model.Parameters.Add(p.key, p.value)
end
end
$container.Register(ComponentRegistration.new(model))
end

How do you run this script? From command line (ir.exe script.rb) or do
you use hosting API?

This is the entire method:

ScriptEngine engine = Ruby.GetEngine(runtime);
var ctx = Ruby.GetExecutionContext(runtime);
ctx.DefineReadOnlyGlobalVariable(“container”, container);

string header =
@"require ‘Castle.Windsor’

require ‘Castle.Core’

ComponentRegistration =

def component(options)
throw :classIsRequired if !options.has_key?(:class)

end
model = ComponentModel.new(name, service, klass)

parameters = options[:parameters]
parameters.each do |p|
model.Parameters.Add(p.key, p.value)
end
end
$container.Register(ComponentRegistration.new(model))
end";

ScriptSource headerSource = engine.CreateScriptSourceFromString(header);
headerSource.Execute();

string containerScript = reader.ReadToEnd();
ScriptSource source =
engine.CreateScriptSourceFromString(containerScript);
source.Execute();
}
}

You can try using the LoadAssembly method on the runtime object

runtime.LoadAssembly(typeof(IWindsorContainer).Assembly);

that should require the assembly a little nicer

I think you can also use load_assembly ‘Castle.Windsor’

I tried that and no luck.
It doesn’t seem that the assembly is not being loaded properly. I’m
able to
use methods on the objects fine in the script. However, it is that last
call to the $container.Register(ComponentRegistration.new(model)) where
for
some reason it won’t work.

ComponentRegistration.new() takes a ComponentModel. The error seems to
indicate that it is receiving a ComponentModel even with the same
namespace
prefixes but somehow it’s not able to use it.

Are you using resharper for your unit tests?

2009/3/18 Nathan S. [email protected]

confundido · March 18, 2009, 9:22pm

Good call Ivan.
The LoadAssembly apparently was doing the trick!

Thanks for the help.

BTW, was this the right mailing list for this question? Is there a
users
mailing list?

confundido · March 18, 2009, 8:58pm

If so turn off shadow copy assemblies under Resharper -> options -> unit
testing

confundido · March 18, 2009, 9:25pm

The assembly seems to be loaded twice into 2 different loader contexts.
â€œrequireâ€ with a simple name (as opposed to strong name â€œAssembly,
Version=â€¦, Culture=â€¦, PublicKeyToken=â€¦â€œ or Kernel#load_assembly) uses
Assembly.LoadFrom to load the assembly. If you have a reference to the
assembly in your C# host that loads it using Assembly.Load, which loads
to a different context. So you might end up loading the assembly (and
types that are defined there) twice. The runtime then as two different
Type objects for a single logical type.

Subject: [Ironruby-core] problem

Hi all. I have a question that probably belongs on a users mailing list
but I could not find one.

I get the following error when trying to use my IronRuby windsor
registration script:

System.InvalidOperationException: can’t convert
Castle::Core::ComponentModel into Castle::Core::ComponentModel

I assume this has something to do with the fact that newing up an object
in IronRuby isn’t the same thing as newing it up in C#.

Any suggestions or guidance would be appreciated.

Here is the important IronRuby code:

require ‘Castle.Windsor’

require ‘Castle.MicroKernel’

require ‘Castle.Core’

ComponentRegistration =
Castle::MicroKernel::Registration::ComponentRegistration

ComponentModel = Castle::Core::ComponentModel

Parameter = Castle::MicroKernel::Registration::Parameter

Component = Castle::MicroKernel::Registration::Component

def component(options)

        throw :classIsRequired if !options.has_key?(:class)

Excellent.
Thanks for your help, guys.

I’m now able to use IronRuby for my windsor registration DSL. I’m very
pleased so far.

I have one other question, how can I take a clr type and get its clr
name?

When I do this:
sometype.to_clr_type.class.name

I always get System::RuntimeType

You can try using the LoadAssembly method on the runtime object

runtime.LoadAssembly(typeof(IWindsorContainer).Assembly);

that should require the assembly a little nicer

I think you can also use load_assembly ‘Castle.Windsor’

Subject: [Ironruby-core] problem

Hi all. I have a question that probably belongs on a users mailing list
but I could not find one.

I get the following error when trying to use my IronRuby windsor
registration script:

System.InvalidOperationException: can’t convert
Castle::Core::ComponentModel into Castle::Core::ComponentModel

I assume this has something to do with the fact that newing up an object
in IronRuby isn’t the same thing as newing it up in C#.

Any suggestions or guidance would be appreciated.

Here is the important IronRuby code:

require ‘Castle.Windsor’

require ‘Castle.MicroKernel’

require ‘Castle.Core’

ComponentRegistration =
Castle::MicroKernel::Registration::ComponentRegistration

ComponentModel = Castle::Core::ComponentModel

Parameter = Castle::MicroKernel::Registration::Parameter

Component = Castle::MicroKernel::Registration::Component

def component(options)

        throw :classIsRequired if !options.has_key?(:class)



        klass = options[:class].to_clr_type



        if options.has_key?(:service)

                    service = options[:service].to_clr_type

        else

                    service = klass

        end



        if options.has_key?(:name)

                    name = options[:name]

        else

                    name = klass.class.name.underscore.lowercase

        end



        model = ComponentModel.new(name, service, klass)



        if options.has_key?(:parameters)

                    parameters = options[:parameters]

                    parameters.each do |p|

                                model.Parameters.Add(p.key, p.value)

                    end

        end



        $container.Register(ComponentRegistration.new(model))

end

Subject: [Ironruby-core] problem

Hi all. I have a question that probably belongs on a users mailing list
but I could not find one.

I get the following error when trying to use my IronRuby windsor
registration script:

System.InvalidOperationException: can’t convert
Castle::Core::ComponentModel into Castle::Core::ComponentModel

I assume this has something to do with the fact that newing up an object
in IronRuby isn’t the same thing as newing it up in C#.

Any suggestions or guidance would be appreciated.

Here is the important IronRuby code:

require ‘Castle.Windsor’

require ‘Castle.MicroKernel’

require ‘Castle.Core’

ComponentRegistration =
Castle::MicroKernel::Registration::ComponentRegistration

ComponentModel = Castle::Core::ComponentModel

Parameter = Castle::MicroKernel::Registration::Parameter

Component = Castle::MicroKernel::Registration::Component

def component(options)

        throw :classIsRequired if !options.has_key?(:class)



        klass = options[:class].to_clr_type



        if options.has_key?(:service)

                    service = options[:service].to_clr_type

        else

                    service = klass

        end



        if options.has_key?(:name)

                    name = options[:name]

        else

                    name = klass.class.name.underscore.lowercase

        end



        model = ComponentModel.new(name, service, klass)



        if options.has_key?(:parameters)

                    parameters = options[:parameters]

                    parameters.each do |p|

                                model.Parameters.Add(p.key, p.value)

                    end

        end



        $container.Register(ComponentRegistration.new(model))

end
