Retrieving images from GridFS using django-tastypie-mongoengine

[Hélio Miranda]

I have a project in Django, and I'm using mongoengine to save images into a Mongo database using GridFS.

All ok so far, but the problem is... when trying to retrieve the images via http request, with a REST API made with django-tastypie-mongoengine, I get back a json object like this:

{"file": "<GridFSProxy: 516ed7cf56ba7d01eb09f522>", "id": "516ed7cf56ba7d01eb09f524", "resource_uri": "/api/v1/movie/516ed7cf56ba7d01eb09f524/"}

Does anybody know how could I get the file from GridFS via http request?

Thanks!

Are you using mongoengine's GridFSStorage?

[Hélio Miranda]

No, I'm not using GridFSStorage.

I was just using mongoengine, with FileField field.

To get the image have to use GridFSStorage?

How to use it?

[Ryan Nowakowski]

GridFSStorage[1] is a Django storage backend[2]. You can override the
default storage backend for FileField[3] to use GridFSStorage[4] or set the
default storage for all FileFields to be GridFSStorage.

But then so was not save in mongodb but in a folder on the server right?

And then as these associated files to records that are in mongodb?

And I'm not using Models, I am using as mongoengine:

class Movie(mongoengine.Document):

    MovieTitle = StringField(max_length=100, required=False)

    MovieCover = FileField()
