带有 Apache 的 django-rest-framework-datatables 显示 414 URI 太长错误

Question

Pre-requisites

• OS - Centos 7
• Python 3.6.4
• Django 3.0 (or 3.1.1)
• Django Rest framework 3.11.1
• django-rest-framework-datatables 0.5.0
• Apache 2.4
• ORACLE 19.1

I have a simple Rest API - which fetches all data from a table in Oracle database. This Django Framework is hosted on Apache webserver. This data is fed into a datatable using the django-rest-framework-datatables.

• When I fetch data from the API using djangorest framework it works well.
• When I fetch data using the template with ?format=datatables as the query parameter the URL is changed and it becomes a very long URL since my table consists of 50-60 columns.
• Thus throws a 414 error.

Did anybody else face this error?

It works well with the django's inherent webserver but when used using Django fails.

Answer 1

Django-rest-framework datatables also support POST requests which solves this particular problem of too long GET URIs, see:

https://django-rest-framework-datatables.readthedocs.io/en/latest/tutorial.html#using-datatables-via-post-method

and:

Answer 2

Yes, I faced such issue and reconfigured the code to shorten the URI.
