BaseTemplateKey tk = new NameOnlyTemplateKey("page", ResolveType.Include, new NameOnlyTemplateKey(null, ResolveType.Include, new NameOnlyTemplateKey()));
etc
So far the only way I can understand how to use a template is to read the
*.cshtml file with a TextReader and pass that into Engine.Razor.RunCompile(). I feel there has to be a cleaner way of doing this, especially with all the classes I am seeing like TemplateManager, CachingProvider, TemplateKey etc... I just cant seem to find a good example of how to use one or all of these to automatically parse a template which i have created in my project. any help would be much appreciated!
@mpbill Well you normally don't create TemplateKey instances yourself, those should be created by the TemplateManager. The manager and the IRazorEngineService provide APIs for this. More documentation can be found here: https://antaris.github.io/RazorEngine/TemplateManager.html. NOTE:
context needs to be null for at least some templates. The idea is that the context gets set by RazorEngine when an inner template is resolved, but at the same time give you a possibility to pre-compile those templates.
Excellent. I've created a spike branch to see how feasible it is to isolate the Razor compilation into separate assemblies as I think this will help with CoreCLR support as well. I think we talked a long time ago about trying to modularize some of the functionality so maybe separating out the AppDomain support is a pre-requirement for CoreCLR support.
My spike isn't going very well trying to brute-force the separation of the MS Razor bits from RazorEngine.Core :(. I think it needs a bit more thought as it is quite tightly coupled to MS Razor throughout the code base. Theoretically I think only the "template"->"source code" stage of the pipeline should depend on MS Razor? I also think I need to separate the configuration into configuration of our pipeline and configuration of the individual view engines (e.g. we could still support CodeInspectors in Razor2 & 3 then as it would be part of their configuration not the global configuration). As this change would force some configuration I'm not sure if it would be worth keeping the static Engine.Razor service.
Yeah I tried as well and had a similar experience (see the split_api branch). Theoretically, yes you are correct. However there is a hidden dependency after we load the generated assembly and load the instance - as then we again need to have the type information for the 'TemplateBase' class which might depend on the MS Razor version... About the static class I'm not really sure if we need it (but a lot of users are used to use the library like this...). Maybe I shouldn't have shipped it with the new API, but I wanted to have an easy upgrade path.
Hi, I'm been having a problem with Engine.Razor.Compile method in a WCF app as of RazorEngine 3.7.5 (tried 3.7.7). Here's my stackoverflow question: http://stackoverflow.com/questions/35512454/razorengine-3-7-7-error-when-compiling-a-cached-template
Any ideas of a solution to fix that problem would be appreciated.
Hi, I'm having an issue while "RazorEngine.RunCompile" view, where the "@model " is defined:
System.MissingMethodException: Method not found: 'Void Microsoft.AspNet.Razor.Parser.ParserContext.OnError(Microsoft.AspNet.Razor.SourceLocation, System.String)'.
at RazorEngine.Compilation.CSharp.CSharpCodeParser.ModelDirective()
System.MissingMethodException: Method not found: 'Void Microsoft.AspNet.Razor.Parser.ParserContext.OnError(Microsoft.AspNet.Razor.SourceLocation, System.String)'.
at RazorEngine.Compilation.CSharp.CSharpCodeParser.ModelDirective()
It is "Microsoft.AspNet.Mvc": "6.0.0-rc1-final" + "RazorEngine": "4.2.7-beta1"
@WalkingMist No, because the default caching provider allows to compile the same template with different types: https://github.com/Antaris/RazorEngine/blob/master/src/source/RazorEngine.Core/Templating/InvalidatingCachingProvider.cs#L23
there is no way to know the type from a template at least. Consider for example layout templates, they can use whatever type their children is using
so I would say there is no sane way to do it. maybe some heuristic. the realquestion is what you want to achieve...
@matthid, what I am trying to do is a message template engine, where I would like to have a single method to call and given the Template Key and a dictionary of parameters and be able to construct the final message. So I would like to have a method on the engine where I give it a template key and it will give me a new instance of the correct ViewModel so that I can populate it somehow
maybe it is too complex, so I have changed my mind and now the caller will construct the correct ViewModel type before passing that to the engine
You can even take it a step further and decorate your ViewModel class with an attribute that holds the template key. Then the caller doesn't need to know about that, but just pass the view model and your engine can resolve the template key automatically.
@matthid I am not so sure about dynamic objects, never used it before, maybe it's time to look that up
I can get the sample with the Anonymous Types running just fine
But I can't seem to use a List<Person> without having an exception blast in my face..
Can anyone help me out please? this is my simplified code
