## Django Setup

### settings.py

```python
INSTALLED_APPS = [
...
's3direct',
...
]

# AWS keys
AWS_SECRET_ACCESS_KEY = ''
AWS_ACCESS_KEY_ID = ''
AWS_STORAGE_BUCKET_NAME = ''

# The region of your bucket, more info:
# http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region
S3DIRECT_REGION = 'us-east-1'

# Destinations in the following format:
# {destination_key: (path_or_function, auth_test, [allowed_mime_types], permissions, custom_bucket)}
#
# 'destination_key' is the key to use for the 'dest' attribute on your widget or model field
S3DIRECT_DESTINATIONS = {
# Allow anybody to upload any MIME type
'misc': ('uploads/misc',),

# Allow staff users to upload any MIME type
'files': ('uploads/files', lambda u: u.is_staff,),

# Allow anybody to upload jpeg's and png's.
'imgs': ('uploads/imgs', lambda u: True, ['image/jpeg', 'image/png'],),

# Allow authenticated users to upload mp4's
'vids': ('uploads/vids', lambda u: u.is_authenticated(), ['video/mp4'],),

# Allow anybody to upload any MIME type with a custom name function, eg:
'custom_filename': (lambda original_filename: 'images/unique.jpg',),

# Specify a non-default bucket for PDFs
'pdfs': ('/', lambda u: True, ['application/pdf'], None, 'pdf-bucket',),

# Allow logged in users to upload any type of file and give it a private acl:
'private': (
'uploads/vids',
lambda u: u.is_authenticated(),
'*',
'private')

# Allow authenticated users to upload with cache-control for a month and content-disposition set to attachment
'cached': (
'uploads/vids',
lambda u: u.is_authenticated(),
'*',
'public-read',
AWS_STORAGE_BUCKET_NAME,
'max-age=2592000',
'attachment')
}
```

### urls.py

```python
urlpatterns = patterns('',
url(r'^s3direct/', include('s3direct.urls')),
)
```

Run ```python manage.py collectstatic``` if required.

## Use in Django admin only

### models.py

```python
from django.db import models
from s3direct.fields import S3DirectField

class Example(models.Model):
video = S3DirectField(dest='destination_key_from_settings')
```

## Use the widget in a custom form

### forms.py

```python
from django import forms
from s3direct.widgets import S3DirectWidget

class S3DirectUploadForm(forms.Form):
images = forms.URLField(widget=S3DirectWidget(dest='destination_key_from_settings'))
```

You can create a custom template by passing in a string with your own HTML to the `html` keyword argument. For example:

```python
from django import forms
from s3direct.widgets import S3DirectWidget

class S3DirectUploadForm(forms.Form):
images = forms.URLField(widget=S3DirectWidget(
dest='destination_key_from_settings'
html=(
'<div class="s3direct" data-policy-url="{policy_url}">'
' <a class="file-link" target="_blank" href="{file_url}">{file_name}</a>'
' <a class="file-remove" href="#remove">Remove</a>'
' <input class="file-url" type="hidden" value="{file_url}" id="{element_id}" name="{name}" />'
' <input class="file-dest" type="hidden" value="{dest}">'
' <input class="file-input" type="file" />'
' <div class="progress progress-striped active">'
' <div class="bar"></div>'
' </div>'
'</div>'
)))
```

### views.py

```python
from django.views.generic import FormView
from .forms import S3DirectUploadForm

class MyView(FormView):
template_name = 'form.html'
form_class = S3DirectUploadForm
```

### templates/form.html

```html
<html>
<head>
<meta charset="utf-8">
<title>s3direct</title>
{{ form.media }}
</head>
<body>
<form action="" method="post">{% csrf_token %}
{{ form.as_p }}
</form>
</body>
</html>
```

## Examples
Examples of both approaches can be found in the examples folder. To run them:
```shell
$ git clone [e-mail]:bradleyg/django-s3direct.git
$ cd django-s3direct
$ python setup.py install
$ cd example

# Add your AWS keys to settings.py

$ python manage.py syncdb
$ python manage.py runserver 0.0.0.0:5000
```

Visit ```http://localhost:5000/admin``` to view the admin widget and ```http://localhost:5000/form``` to view the custom form widget.
