  Or I wonder if the

  buildStateFromSchema

  function might do it for you!

  
  

  
  

  Try passing in the fields array into buildStateFromSchema and see what happens

  Oooh you got me excited, let me give that a go! 👀

  
  

  
  

  Hmmm doesn't seem to be quite what I need, this is what

  buildStateFromSchema

  returns:

  
  
  

  {
    title: {
      valid: true,
      value: 'Title in German',
      initialValue: 'Title in German',
      validate: [Function (anonymous)],
      condition: undefined,
      passesCondition: true
    },
    slug: {
      valid: true,
      value: 'slug-in-german',
      initialValue: 'slug-in-german',
      validate: [Function (anonymous)],
      condition: undefined,
      passesCondition: true
    },
    ...
  }

  hm

  
  

  
  

  what about

  reduceFieldsToValues

  ?

  
  

  
  

  or wait

  
  

  
  

  the main problem is parsing more complex blocks isn't it?

  
  

  
  

  e.g. blocks with subfields?

  You could always just import your collection config directly

  
  

  
  

  But again, you would probably need to still handle nested fields

  wouldn't that result in the same data compared to using req.payload.config.collections?

  Likely, but you could skip the faff of filtering from the collections array if you want to get the config of a specific static collection

  Yeah getting the full config is pretty straightforward here one way or the other, the tricky part is mapping the data to their associated field config... 🤔

  You might have to make a recursive parser to get the output you specifically want

  Another to approach the problem I have could be to find a way to emulate the

  afterChange

  state of the doc with

  locale: "all"

  .

  
  
  

  For example, following my initial example, if I could get:

  
  

  {
    id: '642609c1a7d2bc624df538da',
    title: { 
      en: 'Title in English', 
      de: 'Title in German' 
    },
    slug: { 
      en: 'slug-in-english', 
      de: 'slug-in-german' 
    },
    excerpt: { 
      de: 'The excerpt goes here.' 
    },
    _status: 'draft',
    createdAt: '2023-03-30T22:14:25.318Z',
    updatedAt: '2023-04-05T07:02:50.800Z'
  }

  
  

  ie:

  findByID

  result + the current operation's data, I'd be golden. 🙌

  
  
  

  I may have to do more digging into how Payload work on the inside. 😅

  
  

  
  

  Yeah that's what I started doing and it quickly started feeling a bit "gross". And given that Payload probably already do this somehow somewhere, I figured that I probably shouldn't be reinventing the wheel and that maybe someone would know where the magic happens within Payload - and how to utilize it. 😊

  
  

  
  

  Haven't had the chance to dig more into this yet today, but giving it a bump in case anyone who knows how Payload works on the inside happens to be around and has thoughts. 🙏

  I think the recursive parser is a fine approach, you would just separate your parsing functions into field types and loop over the a collection config and generate this obj/map

  
  
  

  What are you trying to achieve, would a fieldHook work better for you?

  Ah thanks Jarrod! The fieldHook approach could work indeed, although I'd then need to loop over every field in my plugin where I extend the config and add a hook to them. And I'll probably have to go through the same kind of recursive parser to achieve that. 🤔

  
  
  

  That being said, both @thompsonsj (

  ) and @Exo (

  ) might have already solved this in their own plugins, so I'm gonna check their work and learn from it before trying to reinvent the wheel. 😄

  
  
  

  I'll try to remember to close the loop on this thread once I have. 👍
