i already did that and got typescript error Argument of type '{ name: "audio"; title: string; type: "file"; accept: string; }' is not assignable to parameter of type '{ type: "file"; name: "audio"; } & Omit<FileDefinition, "preview"> & { preview?: PreviewConfig<Record<string, string>, Record<never, any>> | undefined; } & FieldDefinitionBase'. Object literal may only specify known properties, and 'accept' does not exist in type '{ type: "file"; name: "audio"; } & Omit<FileDefinition, "preview"> & { preview?: PreviewConfig<Record<string, string>, Record<never, any>> | undefined; } & FieldDefinitionBase'.ts(2345)

Ok. Wait.

this is my whole schema and audio is simply this
defineField({
name: 'audio',
title: 'Audio ',
type: 'file',
accept: 'audio/*',
}),
Mar 19, 2023, 7:26 AM
Robin, your issue is you're not using "options.accept". This is what you're looking for:
            defineField({
              name: 'audio',
              title: 'Audio ',
              type: 'file',
              options: { accept: 'audio/*' },
            }),

user Z
thanks it worked and also can i do conditional rendering here
defineField({
name: 'question',
title: 'Question ',
description: 'Question यहाँ लेख्नुहोस् ',
type: 'string',
validation: (Rule) =&gt; Rule.required().error('Question लेख्नुहोस् यहाँ'),
}),
defineField({
name: 'audio',
title: 'Audio ',
type: 'file',
options: {accept: 'audio/*'},
}), like if there is a text in question, hidden true to audio field and if there is a audio file selected, question field hidden
Mar 19, 2023, 7:29 AM
Yes. You can use Sanity's hidden property as a function, e.g. hidden: ({ parent }) =&gt; !!parent?.question in the audio file will hide it if question has any text in it
Mar 19, 2023, 7:31 AM
The related documentation is a great place to start: https://www.sanity.io/docs/conditional-fields
Mar 19, 2023, 7:32 AM
user Z
thanks, that worked out too, and now here defineField({ name: 'setNumber',
title: 'Set Number',
description: 'यहाँ Set Number लेख्नुहोस् र यो नम्बर दोहोर हुनु हुँदैन।',
type: 'number',
validation: (Rule) =&gt; [Rule.required(), Rule.min(1)],
placeholder: 'eg: 1',
}),
defineField({
name: 'slug',
title: 'Slug',
description: 'Set Number लेखेपछि Generate बटनमा क्लिक गर्नुहोस्',
type: 'slug',
options: {
source: 'setNumber',
slugify: (input) =&gt; 'set-' + input,
},
validation: (Rule) =&gt; Rule.required(),
}), can i also generate slug without even clicking on generate button, i want it hidden and it has to get auto generated when i type setNumber,
Mar 19, 2023, 7:38 AM
user U
While you can do that, I believe you'd need to go a bit too far to make that one happen, so best leave the slug field visible
Mar 19, 2023, 7:39 AM
you know how clients are, they are stupid. they want it hidden and gets auto generated
Mar 19, 2023, 7:40 AM
user U
I would tell them to settle for this one. In order to make this happen you'd need to write a custom component for your type, which would take you some time, but it's still possible
Mar 19, 2023, 7:41 AM
user Z
and now here defineField({ name: 'questions',
title: 'Questions',
type: 'array',
of: [
{
type: 'object',
name: 'set',
title: 'Set',
fields: [
defineField({
name: 'questionNumber',
title: 'Question Number',
description: 'यहाँ Question Number दिनुहोस् र नम्बर दोहोर हुनु नदिनुहोस्।',
type: 'number',
validation: (Rule) =&gt; [
Rule.required().error(
' यहाँ Question Number दिनुहोस् र नम्बर दोहोर हुनु नदिनुहोस्।'
),
Rule.min(1).error(' 1 भन्दा बढी नम्बर हुनुपर्छ'),
],
placeholder: 'eg: 1',
}), can i make the question number auto incremented
Mar 19, 2023, 7:41 AM
The documentation will mostly answer all of those questions as you walk through it. You're looking for this: https://www.sanity.io/docs/initial-value-templates#f853d3151a21
Mar 19, 2023, 7:44 AM
Now, I am not particularly aware if you can read document information from initialValue, but there's the fetch route
Mar 19, 2023, 7:45 AM
If your question number is just its index + 1, you don't need a question number at all in your schema, right?
Mar 19, 2023, 7:45 AM
If a field's value is always derived from another field, the field shouldn't exist in the first place, technically speaking
Mar 19, 2023, 7:46 AM
and now this is the final question i swear🥳🥳, can i make the string or even number field unique?
