how to do file uploads via api about django-s3direct

[bradleyg]

Sure, you can call get_upload_params with 3 post params:

POST /s3direct/get_upload_params
type=video/quicktime
filename=filename.mov
dest=s3DirectDestinationFromSettings

Which returns all of the fields required to post directly to S3:

{  
  "policy":"generated-policy",
  "acl":"public-read",
  "signature":"JeEUf7TNFv5qOk3NmKAZaeIRZbk=",
  "form_action":"https://s3-eu-west-1.amazonaws.com/my-bucket",
  "key":"files/filename.mov",
  "Content-Type":"video/quicktime",
  "AWSAccessKeyId":"my-aws-key",
  "success_action_status":"201"
}

You can then post the file directly:

POST https://s3-eu-west-1.amazonaws.com/my-bucket
policy=generated-policy
acl=public-read
signature=JeEUf7TNFv5qOk3NmKAZaeIRZbk=
key=files/filename.mov
Content-Type=video/quicktime
AWSAccessKeyId=my-aws-key
success_action_status=201
file=binary

i have this code right now

content_type = "image/JPEG"
key = 'uploads/filename.jpg'
acl = 'public-read'
bucket = None
params_raw = create_upload_data(content_type,key,acl,bucket)

params = { 'policy': params_raw['policy'],'acl':acl,'signature':params_raw['signature'],'key':params_raw['key'],'Content-Type':params_raw['Content-Type'],'AWSAccessKeyId':params_raw['AWSAccessKeyId'],'success_action_status':params_raw['success_action_status'],'file': binary_data}
r = requests.post(params_raw['form_action'],data=params,files=dict(foo='bar')) 
return JsonResponse({'request':str(r.text)},safe=False)

but for some reason I am getting back
{"request": "\nInvalidArgument Bucket POST must contain a field named 'key'. If it is specified, please check the order of the fields.keyA68024822D18802EqCwAGDupGKUViTrwXYrKHhDdOWJzq1oWpjz+q/yrWzVPLvrmty3JgZEVdHyrs/8NeagWNZQ409s="}

whats the reason for this? sorry to bug you I know this really isn't in the scope for this. Thanks for the great add on and all the help!

Problem was that dictionaries aren't ordered in python you must use an ordered dictionary.

@bradleyg Can you update this to the latest version as it have changed since then? I am trying to use this as an API along with React JS frontend but I am not sure the requests I need to make. If you update it I'll submit a PR to the documentation adding how to use with React / Front end JS lib
