Pyramid Listing contains pyramid resources and helpers for pagination of result lists

Project description

Pyramid List Pagination

Pyramid List Pagination contains pyramid resources and helpers for pagination
of result lists.

A lot of pyramid_ applications that use a (SQL) database need to list the result
of queries. This result list might get quite long and are split into several
pages. This package is offering some help in this.


Lets assume, that you'd like to start a cheese shop and define a simple
database model in the pyramid application::

from .meta import Base

class Cheese(Base):
id = Column(Integer, primary_key=True)
name = Column(Text, nullable=False)

To get a result list including pagination, just create a sub-class from
:class:`pyramid_listing.SQLAlchemyListing` and define a ``get_base_query``

from pyramid_listing import SQLAlchemyListing

class CheeseList(SQLAlchemyListing):

def get_base_query(self, request)
return request.dbsession.query(Cheese)

In a view you could then use this class to autmagically get paged results::

def cheese_list_view(request):
listing = CheeseList(request)
return {'cheeses': listing.items(), 'pagination': listing.pages}

With this URLs you could access different result pages:

shows page 3:

shows page 1 with 42 items per page:


* automatically calculate pagination information like first, next or last page
from `pyradmid.request.GET` parameters
* loading configuration defaults from .ini files
* easily implement ordering and filtering of results
* helper method for creating `pyradmid.request.GET` parameters for different
* base class for listings as location aware pyramid resources

This package was created with Cookiecutter_ and the
`audreyr/cookiecutter-pypackage`_ project template.

0.1.8 (2018-03-18)
* changed SQLAlchemyListing.pages to a calculated property:

Just creating a SQLAlchemyListing instance does not automatically trigger
a database query. It will only execute this first query if pagination
information is accessed, e.g. in a ordered query.

0.1.7 (2018-03-14)
* applied filters can now be accessed via ``SQLAlchemyListing.filters``

0.1.6 (2018-03-13)
* updated documentation setup for

0.1.5 (2018-03-13)
* code adjustments after liniting

0.1.4 (2018-03-13)
* fixed bug where settings as strings were not parsed correctly
* changed default implementation of __getitem__() to use base_query
* changed ordered_query from a calculated property to a real one

0.1.3 (2018-03-12)

* The classes and the includeme() function are now exposed in the

0.1.2 (2018-03-12)

* The pagination calculation class can now be configured in ``Listing`` and
``Resource`` classes. This enables the use of different pagination defaults
in different lists.

0.1.1 (2018-03-12)

* Untangled Pagination configuration from includeme() function. Pagination
(sub-) classes can now be configured via the ``configure()`` method

0.1.0 (2018-03-11)

* First Working Implementation
