Django Pass file from one view action to another
pickle the file and store the pickle details in session from the view and access the pickle details from session in another view .
I have a view with two actions.
First one renders FileInput for csv. After submit, I read csv header and render the template for second action with dropdown containing header items. 
After dropdown items are selected and submitted, I want to read csv file, saving selected columns to db in second action.
How can I pass file from one action to another?
