Django Import-Export is a powerful and flexible tool for importing and exporting data in a Django application. It allows you to easily import and export data from various formats, such as CSV, Excel, and JSON. It also provides a simple and consistent interface for working with data, making it easy to integrate with other parts of your Django application.
To get started with Django Import-Export, you first need to install it by running the following command:
pip install django-import-export
Then, you need to add it to your Django project
INSTALLED_APPS list in the
INSTALLED_APPS = ['import_export']
Once you’ve done that, you can begin using Django Import-Export in your views, forms, and models. Here’s a quick example of how you might use it in a view:
from django.shortcuts import render from import_export import resources from .models import Books class BooksResource(resources.ModelResource): class Meta: model = Books def export_data(request): book_resource = BooksResource() dataset = book_resource.export() response = HttpResponse(dataset.xls, content_type='application/vnd.ms-excel') response['Content-Disposition'] = 'attachment; filename="Books.xls"' return response
In this example, we first import the
resources module from the
import_export package, as well as our Django model. We then create a resource class for our model, specifying the model to use in the
Meta class. In our view function, we create an instance of this resource class, and use the
export() method to export the data from our model to an Excel file.
We also can import data from different file formats like CSV, XLS, XLSX, JSON and many more using the
from django.shortcuts import render from import_export import resources from .models import Books class BooksResource(resources.ModelResource): class Meta: model = Books def import_data(request): if request.method == "POST": book_resource = BooksResource() dataset = Dataset() new_persons = request.FILES['myfile'] imported_data = dataset.load(new_persons.read()) result = book_resource.import_data(dataset, dry_run=True) # Test the data import if not result.has_errors(): book_resource.import_data(dataset, dry_run=False) # Actually import now return render(request, 'books/import.html')
This is a basic tutorial on how you can use Django Import-Export to easily import and export data in your Django application. There are many other features and options available, such as field-level options, export/import filters, and more. You can check the documentation for more details and examples.
