how to create dynamic mapping with elasticsearch_dsl

Question

I have to create mapping which should look something like this.

{
  "mappings": {
    "properties": {
        "product_id": {
            "type": "keyword"
        },
        "attributes": {
            "dynamic": "true",
            "properties": {}
        },
    }
}

I would normally do something like this

class RetailerProductGeneric(Document):
    product_id = Keyword()

how do I do it when I have a dynamic schema in the document ?

I looked at the docs but not very clear to me. It goes as follows:

class Post(Document):
    title = Text()

    class Meta:
        all = MetaField(enabled=False)
        dynamic = MetaField('strict')

not sure what is happening here. Can someone please explain how to do it?

EDIT 1:

After some research, I figured how to create the dynamic mapping.

class RetailerProductGeneric(Document):
    product_id = Keyword()
    attributes = Object(dynamic=True)

but now expected mapping turns out to be like this

  "attributes": {
    "dynamic": true,
    "type": "object"
  },

what I am looking for is

  "attributes": {
    "dynamic": "true",
    "properties": {}
  },

What difference does it make? How Can I make the mapping as expected.

Actually, how to get the dynamic template mapping was my original question, which I eventually figured out. Later I was confused about a part that you answered. since I dint get any response in first 2 days, I started bounty. — Ojas Kale

Good start!!

"attributes": {
  "dynamic": true,
  "type": "object"
},

and

"attributes": {
  "dynamic": "true",
  "properties": {}
},

are actually exactly the same thing.

When type: object is specified, properties: {} is implied

And when properties: {} is specified and no type is given, then type: object is implied.
