How to store files in djangos array field
django, postgresql, python
Solution
Currently, I think the `django.contrib.postgres.fields.ArrayField` is in active development. The `django.contrib` package is new to django 1.8 (which is still in beta) so I think this functionality is too early to count on.
The text field you are seeing is meant to be a delimited string which is saved in the array. It kinda makes sense with an array of `FileFields` because the `FileField` saves a URL string and not a blob of the file (as far as I can tell).
A `\d table` gives the table information on that column as follows:
arrayexample=# \d example_post
Column | Type | Modifiers
--------------------------------------------------
attachments | character varying(100)[] |
Currently the field you are seeing in admin is created from here. Notice it inherits from `forms.CharField` while a `FileField` uses forms.ClearableFileInput.
I don't think the functionality you are looking for currently exists in Django but I think it is feasible to build it. Personally, I would approach building it by subclassing the existing `ArrayField` and overriding the formfield to use my custom `form_class` to better handle an `Array` of `FileField`s.
I hope this helps, I also don't see any open pull requests for this feature.
Problem
I'm playing around with django.contrib.postgres.fields.ArrayField in django 1.8 alpha and try using it with a file field. Here's a post in a fictional forum: ``` # coding=utf-8 from backend.core.models import Team from django.contrib.postgres.fields import ArrayField from django.db import models from django.db.models import FileField class Post(models.Model): title = models.CharField(max_length=256) content = models.TextField() team = models.ForeignKey(Team, related_name='posts') attachments = ArrayField(FileField(), null=True) def __str__(self): return self.title ``` The migration worked and everything is looking great. However: Django Admin does not support this field. How would I implement that in code, how can I store / add a new file to this array field and store it's reference in the database?
