INSTALLED_APPS = [ ..., 'django_tables2', 'django_tables2_column_shifter', ..., ]Add path to js script: django_tables2_column_shifter.min.js in your base django template. Script must be add after jquery.js and before </body> tag.
base.html:
{% load static %} <body> ... ... <script src="{% static "jquery.min.js" %}"></script> {# require #} <script type="text/javascript" src="{% static "django_tables2_column_shifter/js/django_tables2_column_shifter.min.js" %}"> </script> </body>
Usage:
To use app, you must inherit your table class from django_tables2_column_shifter.tables.ColumnShiftTable
models.py - create normal model:
from django.db import models class MyModel(models.Model): first_name = models.CharField("First name", max_length=50) last_name = models.CharField("Last name", max_length=50)tables.py - change inherit to ColumnShiftTable:
from django_tables2_column_shifter.tables import ColumnShiftTable from app.models import MyModel # By default you probably inherit from django_table2.Table # Change inherit to ColumnShiftTable class MyModelTable(ColumnShiftTable): class Meta: model = MyModelviews.py - In your view, nothing changes:
from .tables import MyModelTable from .models import MyModel def simple_list(request): queryset = MyModel.objects.all() table = MyModelTable(queryset) return render(request, 'template.html', {'table': table})template.html - use default render_table tag to display table object (using bootstrap3 / bootstrap4):
{% extends "base.html" %} {% load django_tables2 %} {% render_table table %}
Warnings:
Warning : - If you use {% render_table %} tag with queryset (not table class instance), django-tables2-column-shifter will not be work. Queryset does not have template attribute:
{% load django_tables2 %} {% render_table queryset %} {# not work #}Warning : - If you use a different template than django_tables2_column_shifter/table.html to render your table, probably django-tables2-column-shifter will not be work. Your custom template should inherit from django_tables2_column_shifter/bootstrap3.html
Customizing:
If you use more then one instance of the same Table class, you should use a different prefix for each instance:
tab1 = MyModelTable(queryset, prefix='tab1') tab2 = MyModelTable(queryset, prefix='tab2') tab3 = MyModelTable(queryset, prefix='tab3')
To disable shifter mechanism - set False to shift_table_column in your table class (default value is True):
class MyModelTable(ColumnShiftTable): shift_table_column = False ...
By default, all columns from sequence are visible, if you want limit visible columns, override method get_column_default_show(self) like that:
class MyModelTable(ColumnShiftTable): def get_column_default_show(self): self.column_default_show = ['column1', 'column2'] return super(MyModelTable, self).get_column_default_show()
