Make Inferencer to use related objects id rather than the name

I have an issue with Refine Inferencer. I have the following REST response:
json
[
{
"id": "d212dfb9-f17a-4367-80a6-c013ef99037e",
"name": "Some example",
"description": "",
"account": {
"id": "e547940e-f9ec-4aa4-97e6-c2f0edf35a08",
"name": "Default"
}
]
json
[
{
"id": "d212dfb9-f17a-4367-80a6-c013ef99037e",
"name": "Some example",
"description": "",
"account": {
"id": "e547940e-f9ec-4aa4-97e6-c2f0edf35a08",
"name": "Default"
}
]
Then the inferencer tries to find the relation from this URL path: /accounts/Default But it should look it from this path: /accounts/e547940e-f9ec-4aa4-97e6-c2f0edf35a08 How can I make the Inferencer work correctly so it would use the id instead of the name?

Hi @Jugibugi. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To make the Refine Inferencer use the id of related objects rather than the name, you can manually modify the inferred fields by using the fieldTransformer function. This allows you to customize how the Inferencer interprets and processes the fields in your data. Here is how you can achieve this: 1. Use the fieldTransformer function: This function allows you to manually adjust the inferred fields to ensure that the Inferencer uses the id instead of the name. 2. Modify the inferred fields: You can specify how the Inferencer should handle the account field to use the id for the related resource. Here is an example of how you can implement this:
import { useInferencer } from "@refinedev/core";

const MyComponent = () => {
const { data, isLoading } = useInferencer({
resource: "your-resource",
fieldTransformer: (field) => {
if (field.key === "account" && field.type === "relation") {
return {
...field,
accessor: "account.id",
};
}
return field;
},
});

if (isLoading) {
return <div>Loading...</div>;
}

return (
<div>
{/* Render your data here */}
</div>
);
};
import { useInferencer } from "@refinedev/core";

const MyComponent = () => {
const { data, isLoading } = useInferencer({
resource: "your-resource",
fieldTransformer: (field) => {
if (field.key === "account" && field.type === "relation") {
return {
...field,
accessor: "account.id",
};
}
return field;
},
});

if (isLoading) {
return <div>Loading...</div>;
}

return (
<div>
{/* Render your data here */}
</div>
);
};
In this example, the fieldTransformer function checks if the field is a relation type and if the key is account. If so, it modifies the accessor to use account.id instead of account.name. For more detailed information, you can refer to the Modifying the inferred fields (https://refine.dev/docs/packages/inferencer/#modifying-the-inferred-fields) section in the Refine documentation. By using this approach, you can ensure that the Inferencer correctly uses the id for related objects, avoiding the issue of incorrect URL paths. If you need further customization or run into any issues, you can also refer to the How the relations are determined (https://refine.dev/docs/packages/inferencer/#how-the-relations-are-determined) section for more insights on how Refine handles relations. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Ok. I got that kind of resolved but I receive this kind of error when rendering the inferencer: Exception: ReferenceError: accountIsLoading is not defined

Let me check the knowledge base for you. One moment! :books: ---------------------- The error ReferenceError: accountIsLoading is not defined suggests that the generated code by the Inferencer is trying to use a variable that hasn't been defined. This is a known issue that can occur with the Inferencer. To resolve this, you can manually adjust the generated code to ensure that all necessary variables are defined. Here is a step-by-step approach to fix this issue: 1. Identify the problematic code: Locate the part of the generated code where accountIsLoading is being used. 2. Define the missing variable: Ensure that accountIsLoading is properly defined and initialized. Here is an example of how you can manually adjust the generated code:
import React from "react";
import {
IResourceComponentsProps,
useShow,
} from "@refinedev/core";
import {
Show,
TextField,
DateField,
} from "@refinedev/antd";
import { Typography, Space } from "antd";

export const YourResourceShow: React.FC<IResourceComponentsProps> = () => {
const { queryResult } = useShow();
const { data, isLoading } = queryResult;
const record = data?.data;

// Define the missing variable
const accountIsLoading = false; // or set it based on your logic

return (
<Show isLoading={isLoading}>
<Typography.Title level={5}>ID</Typography.Title>
<TextField value={record?.id} />
<Typography.Title level={5}>Name</Typography.Title>
<TextField value={record?.name} />
<Typography.Title level={5}>Account</Typography.Title>
{accountIsLoading ? (
<>Loading...</>
) : (
<>{record?.account?.id}</>
)}
</Show>
);
};
import React from "react";
import {
IResourceComponentsProps,
useShow,
} from "@refinedev/core";
import {
Show,
TextField,
DateField,
} from "@refinedev/antd";
import { Typography, Space } from "antd";

export const YourResourceShow: React.FC<IResourceComponentsProps> = () => {
const { queryResult } = useShow();
const { data, isLoading } = queryResult;
const record = data?.data;

// Define the missing variable
const accountIsLoading = false; // or set it based on your logic

return (
<Show isLoading={isLoading}>
<Typography.Title level={5}>ID</Typography.Title>
<TextField value={record?.id} />
<Typography.Title level={5}>Name</Typography.Title>
<TextField value={record?.name} />
<Typography.Title level={5}>Account</Typography.Title>
{accountIsLoading ? (
<>Loading...</>
) : (
<>{record?.account?.id}</>
)}
</Show>
);
};
In this example, accountIsLoading is defined and set to false. You can adjust this based on your actual loading logic. For more information on how to handle such issues, you can refer to the Inferencer documentation (https://refine.dev/docs/ui-integrations/ant-design/components/inferencer/) and the known issues (https://refine.dev/docs/ui-integrations/ant-design/introduction/#known-issues) section. If you continue to face issues, you might want to check the related GitHub issues for similar problems and their resolutions: - Issue 4679 (https://github.com/refinedev/refine/issues/4679) - Issue 4575 (https://github.com/refinedev/refine/issues/4575) These resources can provide additional context and potential solutions for handling Inferencer-related errors. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Btw, is there a way to run the Inferencer on command line to generate the files?

Let me check the knowledge base for you. One moment! :books: ---------------------- As of now, the Inferencer feature in Refine primarily works on the client-side, meaning you need to navigate to the route for the Inferencer to work. The Inferencer makes requests to your API and bootstraps the code for you. There isn't a built-in CLI switch to run the Inferencer directly from the command line to generate files. However, there has been discussion about this feature in the Refine community. One potential solution mentioned is to have a button in the Inferencer component that shows the generated code and updates the relevant file. Since the Inferencer works on the client-side, it doesn't have direct access to the file system, but this could potentially be handled through Refine's devtools, which has a running local express server that could navigate through your files and update them. For more details, you can refer to the GitHub issue discussing this feature (https://github.com/refinedev/refine/issues/5399). Here is a summary of the discussion from the GitHub issue:
Comment by MEMBER: So we are already generating resources with the Inferencer component, but the thing is, the Inferencer is working on the client-side, which means you need to navigate to the route for the Inferencer to work. The Inferencer will make requests to your API and bootstrap the code for you. Having the Inferencer work through CLI may require a big effort, but it should be possible. One solution could be to have another button in the Inferencer component, where we show the generated code. This button could basically update the relevant file with the generated code. But since the Inferencer works on the client-side, we wouldn't have access to the file system. I think it can be handled through our devtools though. Since devtools have a running local express server, it could navigate through your files and update them.
For now, you will need to manually copy the generated code from the Inferencer modal and paste it into your files. If you are interested in this feature, you might want to follow the GitHub issue for updates or contribute to the discussion. For more information on using the Inferencer, you can refer to the Inferencer documentation (https://refine.dev/docs/guides-concepts/development/#using-inferencer). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
