python - Django Pagination, User selected entry amount error -

i have page form user enters information filter queryset when press submit. upon submission, brought results page displays filtered queryset. have pagination set django interactive drop down user can select how many entries of queryset view per page. got working, issue having make work need global queryset object. i've run issues when several threads using page @ once trying find alternative options using global, still allowing interactive dropdown , pagination.

when try remove global , click on second or subsequent page, query seems wiped out , error saying none object cannot iterated over. tips on alternatives can try avoid error? thanks!

you're going wrong - rather trying remember state of queryset each user , paging based on that, instead set user page request page wants , request server.

you in lot of ways, tastypie or django rest framework can give easy way develop page based api , datatables or similar can allow filter , request pages using ajax.
