Inferencer fail to detect relations
i am making two pages that will have relations between them but antd inferencer fail to detect relations. how to give the right data so realtions can be detected?

Hi @M Farhan Zachary. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

If the
dataProvider
and resources
in your application work in a way that makes it impossible for Inferencer to find the relation
resources, you can manually modify the inferred fields by using the fieldTransformer
function. This function allows you to set the relations and resources manually.
Here is an example of how you can override the field tags with fieldTransformer
:
In this example, the key
is set to "tags", the type
is set to "relation", and the relation
is set to true. The resource
is set to an object with name
and route
properties. The relationInfer
is set to an object with an accessor
property. The accessor
is set to "id".
If the record's tag array does not have any item, the next records on the list do not get mapped with the accessor key. To solve this, you may need to make some changes to the file while debugging.
For more information about modifying the inferred fields, you can refer to the Modifying the inferred fields (https://refine.dev/docs/packages/inferencer#modifying-the-inferred-fields) section in the refine documentation.
If you are using multiple data providers, you need to define a default
property as well. It's required by refine to handle resources without a specific data providers to fallback to that one. Here's the docs (https://refine.dev/docs/api-reference/core/providers/data-provider/#using-multiple-data-providers) for using multiple data providers.
If the inferencer is erroring out, this might be the cause, since it can't find a proper data provider to handle the request, the process is going to fail. If you have different resources for the relations in your data, you can define a resource in the resources
array and pass the data provider name in options.dataProviderName
. Inferencer will use this config to send the requests for the resource.
Please note that Inferencer can only work when there is an API response and scaffolds some boilerplate code. You shouldn't rely on that for building your page, but can be used to get started easier. You can copy the generated code into your page and start from there. source (https://discord.com/channels/837692625737613362/1169979256705654874)

but i think i send the right data @kapa.ai , please send me an example how correct data sent from 2 tables that will detect the relations
Let me check the knowledge base for you. One moment! :books:
----------------------
Sure, I can provide an example of how to handle relational data in Refine.
Let's say you have two resources:
posts
and categories
, and each post has a category. You can fetch the categories of the post by using the useMany
hook. Here's an example:
In this example, we first use the useTable
hook to fetch the posts. Then we extract the category IDs from the posts and use the useMany
hook to fetch the categories. The useMany
hook is enabled only if there are category IDs.
This is how you can handle relational data in Refine. For more information, you can refer to the Refine documentation (https://refine.dev/docs/guides-concepts/tables#relationships-).

@kapa.ai @refinedev_inference…js?v=67a757d5:77696 @refinedev/inferencer is trying to detect relations
@refinedev_inference…js?v=67a757d5:77766 @refinedev/inferencer may send multiple requests to your API for nonexistent resources when trying to detect relations. To learn more about how the inferencer works, visit https://s.refine.dev/how-inferencer-works
@refinedev_inference…js?v=67a757d5:77938 @refinedev/inferencer: Inferencer failed to render this field

relation

{key: '__', fieldable: false, type: 'object', priority: 1}

Object
Let me check the knowledge base for you. One moment! :books:
----------------------
The error message you're seeing indicates that the Inferencer failed to render a field with the key
unit_id
. This could be due to a variety of reasons, such as the field not existing in the data, or the field not being correctly formatted for the Inferencer to understand.
The Inferencer in Refine tries to automatically generate views and codes based on the data structure of the resource. However, it might not always be able to correctly infer the relations between different resources, especially if the data structure is complex or unconventional.
In your case, it seems like the unit_id
field is being considered as a relation, but the Inferencer is unable to determine the related resource. This could be because the related resource does not exist, or the Inferencer is unable to find it due to the way your data is structured.
One way to solve this issue is to manually specify the relations using the fieldTransformer
function. This function allows you to customize the output of the Inferencer, such as setting a custom accessor
property for object
type fields or changing the type
of a field, or changing the resource
for a relation
type. Here's an example of how you can use fieldTransformer
:
In this example, the key
is set to "unit_id", the type
is set to "relation", and the relation
is set to true. The resource
is set to an object with name
and route
properties. The relationInfer
is set to an object with an accessor
property. The accessor
is set to "id".
For more information about how the Inferencer works and how to modify the inferred fields, you can refer to the Refine documentation (https://refine.dev/docs/packages/inferencer#modifying-the-inferred-fields).

Hello @M Farhan Zachary, I believe https://refine.dev/docs/packages/inferencer/#modifying-the-inferred-fields this is what you looking for
