partials do not work

[Cuong Truong]

Hi,
I have a bare minimum test Drab-powered app. In the index.html.drab I have

<%= render "navbar.html" %>

Then, next to index.html.drab I created navbar.html.drab with content

NavBar here

The compiler gives me this error:

== Compilation error in file lib/tgshop_web/views/cms_view.ex ==
** (FunctionClauseError) no function clause matching in :lists.flatten/1    
    
    The following arguments were given to :lists.flatten/1:

As an excuse, I am using Drab and Phoenix for first time!
Thanks a lot

Ah I think it doesn't handle top-level text in a file. It assumes well formed HTML by default (that's how it decorates it for fast updates). Try wrapping the NavBar here with <span>NavBar here</span> or some other element as appropriate and see if that works? If it does then I may need to add some better error reporting. :-)

I think I might see the problem looking in the code as well, let me try to push a fix...

[Cuong Truong]

cool, pls tell me when u pushed. Just try with <div>NavBar here</div>, same error...

[OvermindDL1]

I just pushed it to git, can you try using the master github branch as a dependency and see if that fixes it? If not I'll keep looking. If it works then I can make a release. :-)

[Cuong Truong]

yay! works now, thanks a lot 👍

Awesome! Pushing a new release 0.10.4 now, expect it on hex momentarily. :-)
