Django 1.8 ArrayField append & extend

由 [亡魂溺海] 提交于 2019-12-30 03:51:04
问题 Django 1.8 will come with new advanced field types including ArrayField these rely on PostgreSQL and are implemented at a DB level. PostgreSQL's array field implements an append method. However I can't find any documentation on appending an item to an ArrayField . This would clearly be very useful as it would allow the field to be updated without transferring its entire contents from the db then back to it. Is this possible? If not will it be possible in future? Any pointers to docs I've

Django 1.8.4 makemigrations CreateModel changes field's order

由 坚强是说给别人听的谎言 提交于 2019-12-25 06:39:08
问题 We've just switched to Django 1.8.4 (from 1.6, so first time using migrations), and we've noticed an issue when using the makemigrations command. The issue happens when creating a new model that contains Foreign Keys. The command generates a migration file with the field order changed: it sets all the FKs last, and reorganizes them by alphabetical order. Here's an example : class AnotherRandomModel(models.Model): attr1 = models.FloatField() class AnotherRandomModel2(models.Model): attr1 =

问题 I am using Django 1.8. I have a User model and a UserAction model. A user has a type. UserAction has a time, which indicates how long the action took. They look like this: class User(models.Model): user_type = models.IntegerField() class UserAction: user = models.ForeignKey(User) time = models.IntegerField() Now what I want to do is get ALL users of a certain type along with the sum of the time of their actions.So it would look something like this: {user:1,total_time=5000}, {user:2,total_time

Selecting specific fields using select_related in Django

问题 I have two models Article and Blog related using a foreign key.

I tried using only() and defer() with select_related but both didn't work out. articles = Articles.objects.all().select_related('blog__name').only('blog__name', 'title', 'create_time') The above query resulted in error: Invalid

问题 When I use runserver, it gives this warning message: (1_8.W001) The standalone TEMPLATE_* settings were deprecated in Django 1.8 and the TEMPLATES dictionary takes precedence.
