Project description

About

Listable is a Django package to make the integration of your Djangomodels with Datatables.js easy.

Django-listable was motivated by my repeated need to generate sortableand filterable tables from my Django models for CRUD apps.

The idea is that you should easily be able to go from a model like this:

to a filterable/orderable table in a template like this with as little code as possible:

There are a couple of other similar projects worth checking out to see if they fit yourneeds better:

Settings

Listable currently has 4 settings you can configure to be usedas default values for your table (they can be overriden in the listable template tag).

LISTABLE_DOM

Default datatables sDOM parameter to use. By default listable uses the Bootstrap 3 dom below.:

LISTABLE_PAGINATION_TYPE

LISTABLE_STATE_SAVE

Enable sticky filters by default.:

LISTABLE_PAGINATE_BY

Default page size.:

Usage

There’s four steps to using django-listable

1. Including listable in your settings.INSTALLED_APPS
2. Create a view by subclassing listable.views.BaseListableView
3. Connect the view to a url pattern in your apps urls.py
4. Include the listable template tag in a template

These steps will demonstrated below assuming we havea Django application called staff and we want to create a page on oursite with a list of staff and the department and business they belong to.

with the following models defined:

A full functional example can be found in the demo app included withdjango-listable.

Adding listable to settings.INSTALLED_APPS

To start using django-listable add listable to your INSTALLED_APPS:

Defining a Listable view

To define a listable view, sublcass listable.views.BaseListableViewand set the model that is to be used as the source of data:

Defining Columns for your table

Every listable view must define one or more fields to be displayed as columns in the table.listable fields are defined in a manner similar to ModelForms:

fields

Fields defines an iterable of the columns that you want to display in the table,these fields can either be fields on your model, foreign key lookups, the nameof a callable on your view, the name of a callable on your model or the result of an extraquery.

widgets

Widgets is a dictionary mapping a field to a search widget type. Currently you can useeither text (default) or select inputs. For example:

The choices available in a select widget are currently automaticallypopulated although this will change to allow manual configuration of choicesin the future. The choices are populated based on either the choices optionfor a model field or in the case of a foreign key all the values of the foreignkey lookup. (I hope to make this more flexible in the future)

search_fields (optional)

Search fields are a mapping of field names to the django filter syntax that shouldbe used for searching the table. This can either be a string, an iterable ofstrings or a falsy value to disable searching on that field. For example:

if a field is not declared in search_field’s it a filter using icontains is assumed.

order_fields (optional)

Order fields allows you to define how a column should be ordered (similar toDjango’s ordering or order_by). For example:

headers (optional)

Headers is a mapping of field names to the column name to be displayed. For example by defaulta field name of department__business__name would be converted to “Department Business Name” but thatcould be overriden like so:

select_related

Allows you to use Django’s queryset select_related option for reducing database queries. e.g:

prefetch_related

Allows you to use Django’s queryset prefetch_related option for reducing database queries. e.g:

get_extra

Due to a bug with pagination, using an extra query will result in your entire table being loaded into memory beforebeing paginated :(

You may define a callable get_extra method on your view that should return a dictionary suitablefor use in the Django queryset’s extra method. For example:

A more complex example is given in the “Complete Example” sample below.

Formatting fields

The order in which listable tries to find a method for formatting a field for display is as follows:

1. A method on the actual view:

2. A get_{field}_display callable on the model.

3. A callable on the model:

4. A field on the model.

A listable column is defined using the listable.views.Column data structure.A Column is essentially a namedtuple with the following fields (detailed descriptions below):

Including the listable template tag in a template

To include listable in your templates you need to load the listable templatetags and include the listable_css, a placeholder for the listable tableand the listable tag which tells the template the name of the view to wire the table to.:

with the example above requiring a url something like:

Arguments to the listable tag

The listable tag currently has 1 required argument and five optional keyword args.A full example of the listable template tag looks like:

dom

Overrides the default Datatables sDOM parameter to use.

pagination_type

Overrides the default Datatables sDOM parameter to use.

save_state

Save state enables/disables sticky filters in DataTables.:

css_table_class

Add a css class to your datatables table e.g.:

css_input_class

Add a css class to the datatables column filter inputs e.g.:
