The Razor.SetTemplateBase() method no longer seem to exist?

Okay, wow, I feel dumb... My model class was private. Making it public fixed my issue.

New Post: 'object' does not contain a definition for 'Header'

DeeboSan — Thu, 11 Apr 2013 13:56:37 GMT

Hello,

I'm getting this error when parsing my template even though my model object does have the Header property on it. The odd thing is if I use and anonymous type it works fine. Any ideas how I can fix this? I'm using .NET 4.0.

FAILS
string body = Razor.Parse<EmailBodyModel>(template, model);

WORKS
string body = Razor.Parse(template, new { Header = "xxx"} );

I came accross the discussion below but that appears to be the opposite issue that I have.

Created Issue: RazorEngine and specials characters [910]

Daimakaicho — Wed, 20 Mar 2013 16:02:46 GMT

Hello there,

I'm using your project in an application where my users are able to generate bunch of code through an user-friendly GUI. Even it's work really fine, I just got a little "bug" (well, I know it's not a real bug) with specials characters like thoses ones : ' " < > # etc. Thoses characters are interpreted like in HTML-code (< > etc.) like form, however it's not an awaited behavior.

So, here's my question : is there a way inside RazorEngine to disable this behavior, or should I handle with a method it in my template ?

Thanks for reading. Please excuse me for potential english mistakes.

New Post: Performance Issue when using RazorEngine.Razor.SetTemplateService

I found the solution, I just moved the code that sets the template service to App_Start in global.asax and now everything works great :)

New Post: Performance Issue when using RazorEngine.Razor.SetTemplateService

robi2 — Sun, 10 Mar 2013 18:59:47 GMT

Hi,

I noticed that if I use a base template for my razor views, the views don't get cached and are always begin parsed from scratch.

This is the code i am using:

// Set razor engine base template
                    var config = new RazorEngine.Configuration.TemplateServiceConfiguration
                    {
                        BaseTemplateType = typeof(MyTemplateBase<>)
                    };

                    using (var service = new TemplateService(config))
                    {
                        RazorEngine.Razor.SetTemplateService(service);
                        // Parse the template and also save it to cache
                        m_content.Text = RazorEngine.Razor.Parse(myTemplate, myModel, myCacheName);
                    }

This code runs on every request, and I think that is the problem.

Can someone point me in the right direction?

Thanks,
Robert

New Post: ArgumentNullException when using Assembly.LoadFrom

mrmohsoft — Thu, 28 Feb 2013 11:46:38 GMT

I debugged the code and found that the issue is the RazorEngine is trying to load itself when compile the template but can't find that in the loaded assemblies. So I fixed this problem by install RazorEngine dll in the GAC using .NET Framewok 4 tool with the following command.

Install RazorEngine to GAC 4.0

"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\x64\gacutil" /f /i RazorEngine.dll

New Post: Do I have to use dynamic models?

tojak — Wed, 20 Feb 2013 12:57:39 GMT

Is it necessary to use dynamic models?

I created a class "SampleModelClass" inheriting from abstract class ModelClassBase. I defined properties SampleModelClass.Firstname and SampleModelClass.Lastname.
When calling Razor.Parse<SampleModelClass>(templateContent, sampleModel); I get an exception telling me that Firstname is not found in class "ModelClassBase".

I don't understand why RazorEngine wants to use ModelClassBase? If I use a dynamic model (new {Firstname = "Foo", Lastname = "Bar";) it works fine.

New Post: RazorEngine and shared @helpers

shearer3000 — Fri, 01 Feb 2013 02:27:01 GMT

How do i use a shared helper within a razor view that's compiled by RazorEngine? i have a helper located in App_Code that contains some common markup, but when i call the helper i get a string representation, not raw html.

thanks

Is this problem officially fixed? or do we have go with the work around for now?

New Post: ArgumentNullException when using Assembly.LoadFrom

sergiopereira — Thu, 10 Jan 2013 18:42:19 GMT

Here's what fixed this problem for me. I had to help the runtime load the missing assemblies, so I used the AssemblyResolve event of the current AppDomain and manually loaded the missed assemblies:

        public string RenderText<T>(string templateText, T data)
        {
            AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;
            try {
                return Razor.Parse(templateText, data);
            } finally {
                AppDomain.CurrentDomain.AssemblyResolve -= CurrentDomain_AssemblyResolve;
            }
        }

        private Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args) {
            return Assembly.Load(args.Name);
        }

For me this error was happening in a custom MSBuild task that I wrote using RazorEngine to create a report.

RazorEngine has been moved to Github

http://github.com/Antaris/RazorEngine

Update - An early look at RazorEngine v3
New blog post - http://www.fidelitydesign.net/?p=473

Project Description
A templating engine built upon Microsoft's Razor parsing technology. The RazorEngine allows you to use Razor syntax to build robust templates. Currently we have integrated the vanilla Html + Code support, but we hope to support other markup languages in future.

Using the templating engine couldn't be easier, using a simple syntax, we can do the following:

  string template = "Hello @Model.Name! Welcome to Razor!";
  string result = Razor.Parse(template, new { Name = "World" });

The templating engine supports strict and anonymous types, as well as customised base templates, for instance:

  Razor.SetTemplateBase(typeof(HtmlTemplateBase<>));
  
  string template = 
  @"<html>
      <head>
        <title>Hello @Model.Name</title>
      </head>
      <body>
        Email: @Html.TextBoxFor(m => m.Email)
      </body>
    </html>";
    
  var model = new PageModel { Name = "World", Email = "someone@somewhere.com" };
  string result = Razor.Parse(template, model);

NuGet Distribution

The Razor Templating Engine is available through Nuget (http://nuget.codeplex.com/) in Visual Studio. Simply search for RazorEngine in the package manager, or:

New Post: Are there any plans to release this for System.Web.Razor Version 2.0.0.0

nirman1983 — Fri, 04 Jan 2013 04:28:09 GMT

Hi,

First of all, thanks for developing and sharing this package.This has helped me a lot in my applications.

I am consuming this package in one of my MVC 4 application, and hence facing issues as MVC 4 is referencing System.Web.Razor 2.0.0.0, and RazorEngine package is referencing version 1.0.0.0.. this making the live deployment difficult.

Could you please let us know if there are any plans to release RazorEngine package for S.W.R. V 2.0.0.0?

Thanks

Nirman

New Post: foreach with a single item

myname182 — Mon, 10 Dec 2012 20:38:21 GMT

When iterating an expando object with a Razor foreach, I receive the "'System.Collections.Generic.KeyValuePair<string,object>' does not contain a definition for ..." error. This only happens when there is a single object in the array. As soon as there is more than object in the array, it works.

Is there a workaround for this?

Thank you advance.

Comments: ** Comment from web user: mymatemitch **

Check this link http://www.asp.net/whitepapers/mvc4-release-notes#_Toc303253815 and look at the "Installing ASP.NET MVC 4 breaks ASP.NET MVC 3 RTM applications" section. This problem seems to be caused by VS2012 referencing the wrong versions of certain libraries. In particular, MVC 3 uses Razor 1 and MVC 4 uses Razor 2. If this is not explicitly specified in the csproj, .NET references the latest version by default. I had the same problem and as well as modifying the csproj as per the above link, I also changed System.Web.WebPages, System.Web.Helpers, System.Web.Razor and System.Web.WebPages.Razor to use version 1 in the web.config. Now my MVC 3 site works correctly.

Created Issue: Error when using a base template in the global namespace [850]

IanNewson — Thu, 25 Oct 2012 10:14:28 GMT

Create a base template in the global namespace, e.g.

public class MyTemplateBase : TemplateBase {}

Configure razor engine to use this template:
Razor.SetTemplateService(new TemplateService(new TemplateServiceConfiguration()
{
BaseTemplateType = typeof (MyTemplateBase<>)
}));

No template will be able to be compiled until the base template is put into a specific namespace.

New Post: Usage of BaseTemplateType

Silvochka — Mon, 15 Oct 2012 09:32:45 GMT

Hello.

Can you help me?
I have a BaseTemplateType:

public class MessageTemplateBase<T> : RazorEngine.Templating.TemplateBase<T>
	{
		protected string Subject { get; set; }
		protected string Body { get; set; }
	}

I can Set this class to razor:

var service = new TemplateService(new TemplateServiceConfiguration
			{
				BaseTemplateType = typeof(MessageTemplateBase<>)
			});

Also I have model.

How I can get parsed Subject amd Body separately?
