flask-peewee ships with several useful utilities. If you're coming from the django world, some of these functions may look familiar to you.

Getting objects


Provides a handy way of getting an object or 404ing if not found, useful for urls that match based on ID.

def blog_detail(title):
    blog = get_object_or_404(, Blog.title==title)
    return render_template('blog/detail.html', blog=blog)


Wraps the given query and handles pagination automatically. Pagination defaults to 20 but can be changed by passing in paginate_by=XX.

def blog_list():
    active =
    return object_list('blog/index.html', active)
<!-- template -->
{% for blog in object_list %}
  {# render the blog here #}
{% endfor %}

{% if page > 1 %}
  <a href="./?page={{ page - 1 }}">Prev</a>
{% endif %}
{% if page < pagination.get_pages() %}
  <a href="./?page={{ page + 1 }}">Next</a>
{% endif %}


A wrapper around a query (or model class) that handles pagination.


query =
pq = PaginatedQuery(query)

# assume url was /?page=3
obj_list = pq.get_list()  # returns 3rd page of results

pq.get_page() # returns "3"

pq.get_pages() # returns total objects / objects-per-page
