warum es mich an undefined 'Paginierung' erinnern, wenn ich es definiert habe

Question

Ich traf einen Fehler, wenn ich eine einfache Web-Anwendung benutze Kolben.

jinja2.exceptions.UndefinedError

UndefinedError: 'pagintion' is undefined

der Code direkt unter (/view.py) gezeigt:

page = request.args.get('page', 1, type=int) 
pagination = Post.query.order_by(Post.timestamp.desc()).paginate(
    page, per_page=current_app.config['FLASKY_POST_PER_PAGE'], 
    error_out=False) 
posts = pagination.items 
return render_template('index.html', form=form, posts=posts, 
         pagination=pagination) 

, warum es mich undefinierter 'Paginierung' erinnern, wenn ich es definiert hat. die Zurückverfolgungs unten gezeigt:

Answer 1

<a href="{% if pagination.has_next %}{{ url_for(endpoint, page = pagintion.page + 1, **kwargs) }}{% else %}#{% endif%}">»</a> 

Sie Paginierung hier falsch geschrieben (pagintion).
