django-tables2-reports

With django-tables2-reports you can get a report (CSV, XLS) of any table with minimal changes to your project

Requirements

• Python (supports 2.7, 3.3, 3.4, 3.5, 3.6)
• Django (supports 1.3, 1.4, 1.5, 1.6, 1.7, 1.8. 1.9, 1.10, 1.11)
• django-tables2
• xlwt, openpyxl or pyExcelerator (these are optionals, to export to xls; defaults to xlwt if available)

Installation

• In your settings:

INSTALLED_APPS = (

    'django_tables2_reports',
)


TEMPLATE_CONTEXT_PROCESSORS = (

    'django.core.context_processors.static',

)


# This is optional

EXCEL_SUPPORT = 'xlwt' # or 'openpyxl' or 'pyexcelerator'

Changes in your project

1.a Now your table should extend of 'TableReport'

############### Before ###################

import django_tables2 as tables


class MyTable(tables.Table):

    ...

############### Now ######################

from django_tables2_reports.tables import TableReport


class MyTable(TableReport):

    ...

1.b If you want to exclude some columns from report (e.g. if it is a column of buttons), you should set 'exclude_from_report' - the names of columns (as well as property 'exclude' in table)

class MyTable(TableReport):

    class Meta:
        exclude_from_report = ('column1', ...)
    ...

2.a. If you use a traditional views, now you should use other RequestConfig and change a little your view:

############### Before ###################

from django_tables2 import RequestConfig


def my_view(request):
    objs = ....
    table = MyTable(objs)
    RequestConfig(request).configure(table)
    return render_to_response('app1/my_view.html',
                              {'table': table},
                              context_instance=RequestContext(request))

############### Now ######################

from django_tables2_reports.config import RequestConfigReport as RequestConfig
from django_tables2_reports.utils import create_report_http_response

def my_view(request):
    objs = ....
    table = MyTable(objs)
    table_to_report = RequestConfig(request).configure(table)
    if table_to_report:
        return create_report_http_response(table_to_report, request)
    return render_to_response('app1/my_view.html',
                              {'table': table},
                              context_instance=RequestContext(request))

If you have a lot of tables in your project, you can activate the middleware, and you do not have to change your views, only the RequestConfig import

# In your settings

MIDDLEWARE_CLASSES = (

    'django_tables2_reports.middleware.TableReportMiddleware',
)

############### Now (with middleware) ######################

from django_tables2_reports.config import RequestConfigReport as RequestConfig

def my_view(request):
    objs = ....
    table = MyTable(objs)
    RequestConfig(request).configure(table)
    return render_to_response('app1/my_view.html',
                              {'table': table},
                              context_instance=RequestContext(request))

2.b. If you use a Class-based views:

############### Before ###################

from django_tables2.views import SingleTableView


class PhaseChangeView(SingleTableView):
    table_class = MyTable
    model = MyModel


############### Now ######################

from django_tables2_reports.views import ReportTableView


class PhaseChangeView(ReportTableView):
    table_class = MyTable
    model = MyModel

Usage

Under the table appear a CSV icon (and XLS icon if you have xlwt, openpyxl or pyExcelerator in your python path), if you click in this icon, you get a CSV report (or xls report) with every item of the table (without pagination). The ordering works!

Development

You can get the last bleeding edge version of django-tables2-reports by doing a clone of its git repository:

git clone https://github.com/goinnn/django-tables2-reports

Test project

In the source tree, you will find a directory called 'test_project'. It contains a readily setup project that uses django-tables2-reports. You can run it as usual:

cd test_project
export PYTHONPATH=..
python manage.py syncdb --noinput
python manage.py runserver
