I'm sorry, that's a mistake in the example. You can solve it by replacing blog.children.add with blog.add. I'll update the README to reflect this.

Feel free to report subsequent errors in README here :)

Please comment the assert line and replace it with print(blog.get_url()). What is the output ?

I think it is /api/, which is why the assertion fails.

[SoulRaven]

no problem, is my pleasure

[SoulRaven]

even when i user template='materials/navutil/material_top_menu.html', inside the node,
the default ul tag is render along side with my personal template

normally ul tag will not to be rended

[ovalfog]

I think that u should reset the 'assert'...And,I'm sorry,I know my English is very terrible.....o(╥﹏╥)o
