The line in the auth.py file: return f(_args, *_kwargs)
results in an error: AssertionError: Unimplemented method 'GET'

Any idea why this may be? I followed the tutorial to the word, and everything was fine until I implemented the various post types.

One should completely rewrite this tutorial.

Post defines the following function

def get_absolute_url(self):
        return url_for('post', kwargs={"slug": self.slug})

This function isn't used in the tutorial, but calling it results in a BuildError exception.
The Blueprint for Post is 'posts' not 'post'.
It also doesn't define which 'function' to call, Ie 'posts.detail' or 'posts.list'.

The correct code should be

def get_absolute_url(self):
        return url_for('posts.detail', slug=self.slug)

So, first off, awesome tutorial, and thanks for making it!

But there seems to be an error somewhere, and I am having trouble pegging it. It's somewhere between the section ending just before this one:
http://docs.mongodb.org/manual/tutorial/write-a-tumblelog-application-with-flask-mongoengine/#configure-mongoengine-and-flask

and the end of this one:
http://docs.mongodb.org/manual/tutorial/write-a-tumblelog-application-with-flask-mongoengine/#add-templates

I can successfully run:
python manage.py runserver

at the first point, but not at the second.

I posted question on SO, and the commenters also remembered having to change a couple things to get it to work:

I am not so clever as they were to figure out what.

Hi,

I started this Turial, Here

And get this error

**mongoengine.errors.NotRegistered: ** `Comment` has not been registered in the document registry. Importing the document class automatically registers it, has it been imported?

any idea.
Thank you So much.

In the section Add Data with the Shell, I can follow along with post = Post(.... After post.save() I get a return <Post: Hello world>. So far, so good.

But…

When I go on with comment, I encounter an error.

comment = Comment(
    author="one",
    body="two"
)

Traceback (most recent call last):
File "<console>", line 3, in <module>
TypeError: __init__() takes exactly 2 arguments (1 given)

I compared my __init__.py with the one in your repository, but could not find any difference. Same with models.py.

What am I doing wrong?

Here is my requirements.txt:

in edit post, body part not recognising new line.

I've got error - "OperationFailure: database error: Can't canonicalize query: BadValue bad sort specification" when i used indexes ["-created_at", "-slug"] and ordering - "-created_at" instead of "created_at" and "slug".

Thanks for the tutorial!
The tutorial could benefit from adding links to available option in app.config. The link provided documents the connect() settings for mongoengine. I was only able to find the following options on a stackoverflow.
