26810	DATA_UPLOAD_MAX_NUMBER_FIELDS not taken into account in admin mass actions	Jerome Leclanche	nobody	"In Django 1.10a1, when selecting all items in an admin view with a lot of items and clicking ""Select all 50+ elements"" and proceeding with the action, if the amount of elements exceeds the new `DATA_UPLOAD_MAX_NUMBER_FIELDS` setting, a TooManyFieldsSent error will be raised. The error is not caught by the admin.

Possible resolutions:

* Handle TooManyFieldsSent in admin actions (simple but bad experience)
* Allow a ""select everything"" that does not use individual POST fields (hard, but best experience)
* Check DATA_UPLOAD_MAX_NUMBER_FIELDS in the admin, preventing too many items from being selected (hard, bad experience)"	Cleanup/optimization	new	contrib.admin	1.10	Normal			vytis.banaitis@…	Accepted	0	0	0	0	0	0
