You may just want to set it to None, but check out the description in documentation. https://docs.djangoproject.com/en/1.11/ref/settings/#data-upload-max-number-fields
-----Original Message----- From: django-users@googlegroups.com [mailto:django-users@googlegroups.com] On Behalf Of Mike Dewhirst Sent: Thursday, October 12, 2017 3:08 AM To: django-users@googlegroups.com Subject: DATA_UPLOAD_MAX_NUMBER_FIELDS exceeded when not conducting a mass event re ticket #26810 I have an Admin based application which is somewhat ambitious for the Admin. Perhaps. My central model (substance) has a lot of stuff to do when it is saved. I received the error[1] when saving a substance. Not all substances. In fact only one out of twenty or so I was testing. I thought it must be data related because the substance wasn't different than the others. I could work around the problem by increasing the DATA_UPLOAD_MAX_NUMBER_FIELDS to 1045 I have left it at 1500 for now but I'm somewhat concerned. Why is it so? I don't think there are more than the default 1000 fields. I haven't counted them though.
