Meteor: Strange/buggy behavior using include within foreach on a Cursor object

[Hal Helms]

From what I understand, the filename provided to include is parsed relative to the current file's directory (not documented?). This behavior changes when using include within a foreach on a Meteor Cursor object. For example:

client/zCode/body.js

Template.body.posts = function() {
  return Posts.find().fetch(); // regular Array
};

client/views/body.blade

.container
  include 'posts/posts_list' exposing posts

client/views/posts/posts_list.blade

.posts
  foreach posts as post
    include 'post' exposing post

This code will render the 'posts/post' template three times for three posts in the Array returned by Posts.find().fetch(), as expected.

However, change Posts.find().fetch() to just Posts.find() (which returns a Cursor object), and this error prints each time it tries to run the include:

This can be "fixed" by editing 'client/views/posts/posts_list.blade" and changing include 'post' exposing post to include 'posts/post' exposing post. It then renders the same as before. It seems like a bug to have the template path for include be dependent on whether an Array or Cursor was used, though...

Weird. I will investigate further.

The issue appears to be info.rel is not being carried over properly when using reactive calls in the foreach loop. Or, perhaps, for whatever reason, resolveFilename(info.rel + "/" + relFilename) does not begin with the string "client/views/"

Not to resurrect a dead thread/issue here, but could you simply add console.log(name) right after line 31 in this file: https://github.com/bminer/meteor-blade/blob/master/runtime-meteor.js#L31 ??

Try it then and see what prints to the console before the error message. That would be extraordinarily helpful!

Closing this issue. Dropping Blade + Meteor support for now. :(
