How to implement automatic Custom ID?

[didiraja]

Collection config allow me to overwrite payload ID implement, but can't define defaultValue. Classic ID numbering is not an option to me, to prevent users discovering and playing with other entries, just changing ID.

Would like to fully customize using nanoID but any ID like, its totally fine. Is it possible?

Hey @didiraja,

I was surprised that defaultValue is not allowed for custom ID fields. As another workaround you could add it to the beforeValidate hook like this:

// in your collection:
  hooks: {
    beforeValidate: [({ data }) => {
      if (!data.id) {
        // replace with your own way to generate IDs
        const customID = uuid()
        return {...data, id: customID }
      }
      return data
    }],
  },
  fields: [
    {
      name: 'id',
      type: 'text',
      admin: {
        components: {
          Field: () => null,
        },
      },
    },
 // ... rest of the fields
}]

@didiraja please mark this as answered if it solved your issue. If not, I'm curious what happened.
Thanks!

@DanRibbens worked flawlessly, thanks!

@DanRibbens This is how Payload reacts when I try to overwrite id object using defaultValue:

collection definition:

const Events: CollectionConfig = {
  slug: 'events',
  auth: false,
  admin: {
    useAsTitle: 'title',
  },
  fields: [
    {
      name: 'id',
      type: 'text',
      defaultValue: nanoid(),
      required: true,
    },
    {
      label: 'Título',
      name: 'title',
      type: 'text',
      required: true,
    },

terminal output:
