title: prepopulate an admin field from logged-in User
body: <p>How do I prepopulate an Admin field from logged-in User info?</p>
  
  <p>I have model.py:</p>
  
  <pre><code>from django.db import models  
  class News(models.Model):  
      title = models.CharField(max_length=65)  
      body = models.TextField()  
      author = models.CharField(max_length=55)  
  </code></pre>
  
  <p>and I have admin.py:</p>
  
  <pre><code>from django.contrib import admin
  from django.contrib.auth.models import User
  from newsite.news.models import News
  class NewsAdmin(admin.ModelAdmin):
      list_display = ('title','author')
      search_fields = ['title', 'author']
      prepopulated_fields = {'author': (?????)} 
  admin.site.register(News, NewsAdmin)
  </code></pre>
  
  <p>I have been struggling trying to figure out how to get the currently logged-in user into that prepopulated_field for author.</p>
  
  <p>Any tips would be appreciated.  Thanks.</p>
