### The purpose of this script is to create a version of the database
### that helps a U Mass Amherst researcher look through the OpenHatch
### data and perform text classification and other text analysis.

### To protect our users' privacy, we:
### * set the password column to the empty string
### * set the email column to the empty string
### * delete (from the database) any PortfolioEntry that is_deleted
### * delete (from the database) any Citation that is_deleted
### * delete all WebResponse objects

import mysite.profile.models
import django.contrib.auth.models

### set the email and password columns to the empty string
for user in django.contrib.auth.models.User.objects.all():
    user.email = ''
    user.password = ''
    user.save()

### delete PortfolioEntry instances that is_deleted
for pfe in mysite.profile.models.PortfolioEntry.objects.all():
    if pfe.is_deleted:
        pfe.delete()

### delete Citation instances that is_deleted
for citation in mysite.profile.models.Citation.objects.all():
    if citation.is_deleted:
        


### delete all WebResponse objects
for wr in mysite.customs.models.WebResponse.objects.all():
    wr.delete()
