Is there any way to use a different reference field (other than id) for a ReferenceInput?
For example:
I have a languages resource, which I want to populate using a language_code field.
Note, I don't want to use the id field of languages, I want to use the code field.
I have managed to get it to work by using the following:
<ReferenceInput
label="Language code"
source="language_code"
reference="languages"
>
<SelectInput optionText="name" optionValue="code" />
</ReferenceInput>
The only problem with this is that:
After selecting a language from the select input, the ReferenceInput tries to fetch the resource using the code field rather than the id field, which returns a 404 error.
The value stored as the reference to the languages in the resource must be its identifier. Indeed, if you add a ReferenceField in the show view of your resource, how can it fetch the language without its id ?
You have two options here:
languages/en routelanguage_id in addition to the language_code in your resource and create a custom ReferenceInput which will return both values after selectionCollected from the Internet
