How to make Inferencer automatically generate the fields for the form?
Hello, I hope everyone is doing great today!
I am struggling and confused with a minor problem with the Inferencer, and I need help and insights on this.
I'm using the inferencer, particularly the MUI inferencer, to automatically generate route pages like create, update, list, etc. However, unlike the example provided in the sandbox documentation, my inferencer isn't automatically generating the required fields. I've tried adding meta props and specifying the fields manually, but it's not working as expected.
It's worth noting that I'm using Supabase as the data provider, and according to their documentation, it should generate the expected behavior, including the code for the fields component.
Could someone provide guidance on any additional steps I might need to take to ensure it functions correctly?
Thanks in advance for any help!

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

The Inferencer in Refine is designed to automatically generate basic boilerplate code for your application based on API responses. This includes generating fields for forms in create, update, and list pages. However, it's important to note that the Inferencer is not always reliable for all cases and isn't intended for production use. It's more of a starting point to save time during development.
Here's an example of how you can use the Inferencer to scaffold your pages:
If the Inferencer isn't generating the fields as expected, it could be due to the structure of your API responses. The Inferencer makes a guess and generates some code based on the API responses it receives. If the API responses are not structured in a way that the Inferencer can understand, it might not generate the fields correctly.
You can check the Inferencer documentation (https://refine.dev/docs/guides-concepts/general-concepts#inferencer) for more information on how it works and how the fields are inferred.
If you're still having issues, it might be helpful to manually copy the generated code and modify it according to your needs. As mentioned in a Discord support thread (https://discord.com/channels/837692625737613362/1159695761701871686), the Inferencer just gives you a starting point, and you can modify the generated code as needed.
I hope this helps! If you have any other questions, feel free to ask.

This is what my inferencer generated:

This should be the expected output of the inferencer, as an example:

SOLVED! Upon thorough investigation, I've identified the root cause of the issue. It appears that the oversight lay in neglecting to remove the pre-existing example from the template. This led to an error being triggered upon execution of the request.
Specifically, the error message returned, in my case, was:
{code: '42P01', details: null, hint: null, message: 'relation "public.categories" does not exist'}.
This error stems from the absence of the referenced table, public.categories,
within the database. Consequently, the absence of this table disrupts the entire request process.
I figured this out when I found out that the inferencer
is designed to derive its fields directly from the data provider. Therefore, any discrepancies or inaccuracies within the data source can directly impact the entire inferencing process. In this scenario, the presence of a non-existent table within the database results in the failure of the inferencing mechanism.
