Sometimes, we want to fix CSRF token missing or incorrect with Python Django.

In this article, we’ll look at how to fix CSRF token missing or incorrect with Python Django.

How to fix CSRF token missing or incorrect with Python Django?

To fix CSRF token missing or incorrect with Python Django, we can pass the request context into the form when calling render_to_response.

For instance, in our view, we write

from django.template import RequestContext

# ...

return render_to_response('fileupload/upload.html', {'form': c['UploadFileForm']},  RequestContext(request))

to call render_to_response with RequestContext(request) to pass the CSRF token into the fileupload/upload.html template.

Then in our template, we use

{% csrf_token %}

to add the CSRF token field.

Conclusion

To fix CSRF token missing or incorrect with Python Django, we can pass the request context into the form when calling render_to_response.

Sometimes, we want to modify the request object with Python Django.

In this article, we’ll look at how to modify the request object with Python Django.

How to modify the request object with Python Django?

request.GET = request.GET.copy()

to make a copy of request.GET with request.GET.copy() to return a mutable copy of the dict.

And then we assign the copied dict back to request.GET.

Conclusion

To modify the request object with Python Django, we can use the copy method to make it mutable.

Sometimes, we want to get query string parameters with Python Django.

In this article, we’ll look at how to get query string parameters with Python Django.

How to get query string parameters with Python Django?

To get query string parameters with Python Django, we can use the request.GET property.

For instance, we write

def get_item(request):
    id = int(request.GET.get('id'))
    type = request.GET.get('type', 'default')

in the get_item view function to get the id query parameter with

id = int(request.GET.get('id'))

And we get the type query parameter with

type = request.GET.get('type', 'default')

The type query parameter has default value 'default' if it doesn’t exist.

Conclusion

To get query string parameters with Python Django, we can use the request.GET property.
