问题 I try to implement an image field that you can assign a string to and it will automatically fetch the image from that URL. Reading it afterwards, it will hold the path to the local copy.

问题 I am running django 1.7 & python 2.7. In my postgressql db, I had some surplus tables. I now believe that the surplus tables were made surplus when I changed the names of many of my tables some time ago, before I upgraded to django 1.7. The surplus table names did not have any data in them. After I checked my migrations and after searching my project for the surplus table names and finding no reference, I deleted/droped the tables. I am able to update existing records and add new records, but

问题 Previously in Django 1.6 and earlier versions, I used to do the following to make User 's email attribute unique: class User(AbstractUser): USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['username'] User._meta.get_field_by_name('email')[0]._unique=True I'm migrating to Django 1.7 but this code is raising the following error: django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet. traced all the way back to User._meta.get_field_by_name('email')[0]._unique=True .

问题 I'm trying Django 1.7. This is my TEMPLATE_DIRS setting: TEMPLATE_DIRS = ( os.path.join(os.path.dirname(__file__), 'templates').replace('\\', '/') ) which is fine for Django 1.6, but doesn't work for Django 1.7. Can someone explains this? Thx!! 回答1: You need a trailing , for it to be a tuple, see below, the last , TEMPLATE_DIRS = ( os.path.join(os.path.dirname(__file__), 'templates').replace('\\', '/'), ) When there's a single element in the tuple you need to leave a trailing comma at the end
