Deny all fields except for a few

Hi all,

is there a way to allow only a few specific fields and deny all others?

Background: I have a layer with 30+ fields. I only want the users to see a few of them (let's say 5). Using the UI, I'd have to set a Deny permission for each of the 25+ denied fields. Using Advanced Permissions doesn't really help because even there, I will have to write a denyField()for each field.

Is there a way to do this? What I need would be something like a wildcard, or a denyAllFields() method. The only way I found was to iterate over the fields, like this:

layer.fields.forEach(function (item) {
  denyField(item.name);
});

But this throws a lot of Varint overflow errors, and I believe there should be a better way to do this.

  Hi Marius, 

  This works for us to allow only a few specific fields and denying all others:
   

  const allowedSet = new Set(['type', 'survstatus']);
  // Deny all fields
  layer.fields.forEach((f) => {
      const fname = f && f.name;
      try {
          denyField(fname);
      } catch (e) {
          // Field might not exist on this layer?
      }
  });
  
  // Explicitly allow whitelisted fields
  allowedSet.forEach((fieldName) => {
      try {
          allowField(fieldName);
      } catch (e) {
          // Field might not exist on this layer?
      }
  });

   

  By the way, if you use denyfield do you find you can no longer sort any other fields ?

  Thank you for your replay. Your code works, but I still get the Varint errors.

  And yes, I also get the sorting bug.
