@sandeepsajan0 @theskumar Should we use the "rolepermissions" module for these kind of permissions? I believe it will handle things like template tags automatically.

Implemented here e.g.:

hypha/hypha/apply/funds/permissions.py

Lines 30 to 50 in 2b7fabc

	@register_object_checker()
	def delete_submission(role, user, submission) -> bool:
	"""
	Determines if a user has permission to delete a submission.
	Permissions are granted if:
	- User is a Superuser, or StaffAdmin
	- User has explicit delete_applicationsubmission permission
	- User is the applicant of the submission and it is in draft state
	"""
	if role == StaffAdmin:
	return True
	if user.has_perm("funds.delete_applicationsubmission"):
	return True
	# Allow the user to delete their own draft submissions
	if user == submission.user and submission.status == DRAFT_STATE:
	return True
	return False
