How to use Pydantic base schema to n number of child schema - python-3.x

Question

I'm new to pydantic, I want to define pydantic schema and fields for the below python dictionary which in the form of JSONAPI standard
{
"data": {
"type": "string",
"attributes":{
"title": "string",
"name": "string"
}
}
I managed to achieve this by defining multiple schemas like below,
class Child2(BaseModel):
title: str
name: str
class Child1(BaseModel):
type: str
attributes: Child2
class BaseParent(BaseModel):
data: Child1
But, I will be having multiple json request with the same json API structure as below,
example 1 {
"data": {
"type": "string",
"attributes":{
"source": "001",
"status": "New"
}
}
example 2 {
"data": {
"type": "string",
"attributes":{
"id": "001"
}
}
If you look into the above python dictionary, Values only under the attributes object are different. So, is there any way that I can define a parent marshmallow scheme for { "data": { "type": "string", "attributes":{ } } } and use that parent schema for all child schema's.

I found an answer finally, Hope this will help someone.
Pydantic 'create_model' concept will help to resolve this kind of requirement by passing child schema as one of the field values to create_model.
class Child(BaseModel):
title: str
name: str
class BaseParent(BaseModel):
data: create_model('BaseParent', type=(str, ...), attributes=(Child, ...))
And this will frame a BaseParent schema structure as below,
data=BaseParent(type='id', attributes=Child2(title='test002', name='Test'))
