Razor Code in Orchard Articles / Pages

Topics: Customizing Orchard, Troubleshooting
Apr 8, 2011 at 1:56 PM


I am currently experimenting with Orchard for a new project. I am trying to put some custom Razor code in to the body of an article, but every time I publish the article, the code ends up with <p> tags wrapped around it.

Is there any way of stopping that?

Can you post your code and the resultant HTML? Thanks

The problem I am having, is that the Razor code end's up wrapped in <p></p> tags!

Well... technically what you're doing is illegal in HTML, text shouldn't exist outside of allowable block-level tags (such as <p>).

But if there's a reason you need to force this, you can try:

@{ string message = "This should show here!"; <text>@message</text> }

The <text> tag is actually a razor keyword for "here's some html not wrapped in tags". You see, the Razor parser usually expects to see a complete tag inside curly braces, it's part of how it actually parses the file.

Thanks mate,

That was my fault, the code should of read

@{ string message = "This should show here!"; <p>@message</p> }

However, when I click publish, the whole code block get's wrapped in <p> tags like this:

<p>@{ string message = "This should show here!";</p> <p>@message</p> <p>}</p>

Eek! Really not sure what's going on there, it could actually be the browser doing the wrapping and Razor just isn't even parsing anything.

Try reformatting the code as follows:

    string message = "This should show here!";

Razor can get confused in certain situations if you try to do too much on one line :)

Hi randompete

Thanks for the help there. Tried it your way, but again, everything keeps getting wrapped in <p> tags. Im thinking it could be TinyMce but i'm not sure.

Are there any setting's or something that people know of to stop it happening, or are you not allowed to put Razor code directly into an artice through TinyMce?



Apr 8, 2011 at 2:45 PM

Wait ... you're typing Razor code into TinyMce? That won't work :)

Apr 8, 2011 at 2:51 PM

do you know of any modules that will change the editor to allow it?

Apr 8, 2011 at 2:54 PM

Hang on ... are you trying to actually run the code, or just display it? If you just want to display it, you can wrap it in <pre></pre> and Tinymce won't mess with the formatting.

Apr 8, 2011 at 2:57 PM

Actually run the code. You will have to forgive my ignorance, I have moved over from PHP and this is my first .NET / MVC project. Thanks for all you help so far though :)

Apr 8, 2011 at 3:12 PM

Don''t worry. I actually haven't been using MVC or Razor all that long but I've been using ASP.NET a fairly long time. Razor hasn't even existed until recently :) I'm still constantly learning things.

You've just got to remember Razor is no different to PHP but with a slightly cooler syntax. It's server code, it lives in .cshtml files - that's mixed C# and HTML - so it gets parsed and executed at the server by the runtime.

TinyMCE / body editor are just for editing static HTML or Javascript content that gets rendered "as is" out to the page and parsed by your browser.

So your browser can't understand cshtml and neither can tinymce, it's not part of any widely-used spec, it's just an arbitrary syntax invented by some really awesome developers.

However... there is a system of filters in Orchard that enable scenarios like, for instance, expanding out BBCode from the body and turning it into html.

So it would be technically possible, perhaps using the .NET dynamic runtime (DLR), to parse and execute Razor code in the body during render.

But I wouldn't particularly recommend attempting that, it'd be pretty complicated, and could be extremely dangerous unless you're very careful and it's only you who's going to be editing the content. If you let someone input artitrary code to run on the server you could create all kinds of problems.

If you want to do this kind of customisation, you should be doing it in your Theme where you can write whatever cshtml code you like. The other option is to create a ContentPart and attach it to your Page content type, you can then write cshtml display views for the part.

Thanks mate - given me something to look at :)
