How does DataProvider manage field types?
I am working on a custom data provider, but for some reason, default template I got from refine playground, is showing custom fields as a dropdown and querying APIs for fetching values.
I want to understand how its taking the data type for these fields.

Hi @lostnobody. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Refine uses the
meta
fields to infer the data types of the fields in your data provider's response. This is particularly useful when you're working with GraphQL data providers. You'll need to provide some meta
values beforehand, and then the Inferencer will use these values to infer the fields of the data provider's response, generate a code, and a preview.
For example, if you're working with a Hasura GraphQL Data Provider, by default, the data provider assumes that your ID
type is uuid
. You can change this behavior by using the idType
option. You can pass Int
or uuid
as the value of idType
option or use a function to determine the idType
based on the resource name.
Or, you can pass a function to idType
to determine the idType
based on the resource name.
For more information, you can refer to the Refine Documentation (https://refine.dev/docs/packages/documentation/data-providers/graphql/) and the Hasura Data Provider Example (https://refine.dev/docs/examples/data-provider/hasura/).

Hello @lostnobody, you can check this documentation: https://refine.dev/docs/packages/documentation/inferencer/#how-the-fields-are-inferred
Inferencer
is doing that, and I want to emphasize that it doesn't give you complete code, it just tries to infer some data and generate code for you. You can copy/paste the generated code and modify as you need.
Inferencer just gives you a starting point.Inferencer | refine
