I don't know if that is a Problem with mongoid-simple-tags for sure, but maybe u can help me.

At the moment i'm testing my views with Capybara (1.1.2) and Rspec (2.11.0). When i use the all_tags method of mongoid-simple-tags in my controller i get the following error message:

Failures:

         @fields=nil>

     # ./app/controllers/admin/builds_controller.rb:11:in `index'
     # ./spec/requests/admin/builds_spec.rb:12:in `block (3 levels) in <top (required)>'

If i replace the all_tags method with a simple array ( [name: "test"] ) everything works fine.

Do u have any ideas where i can start to search for the problem?

Thanks, Matthias

When i upgraded mongoid-simple-tags gem version from "0.1.1" to "0.1.2", it was throwing "TypeError - can't convert String into Integer" for my existing model while i tried to access "model.tags"

For example

user.tags
TypeError - can't convert String into Integer

But downgrading to version "0.1.1" works fine

Is there a specific reason why you call to_a on the tagged_with result and not let it return a criteria, which can be used for chaining queries?

the api provided by mongoid changed a lot in v3.

For example, if I have

@posts = Post.where(:live => true)

I would like to do

@tags = @posts.scoped_tags # should really be @posts.all_tags

instead of

@tags = Post.scoped_tags(:live => true)

PS: Is this what calling @posts.all_tags would do?

Yes that's what it does... (I'll just leave this here to educate others)

See https://github.com/mongodb/mongo/blob/master/docs/errors.md
for details about this error.

With Pixel.all_tags this error occurs

I had this in the past, but the only solution I could come up with was to delete the collection and start over...
