Parse-server: How to set CLP?

[sumihiro]

I need to set class level permission to some classes.
I referenced #92, and cheked Schema.js and spec/Schema.spec.js.
Also, set environment PARSE_EXPERIMENTAL_CONFIG_ENABLED=1.

I tried to get config and load schema. But I could not get config.

Parse.Cloud.define('restrict', function(req, res) {
  Parse.Cloud.useMasterKey();

  Parse.Config.get().then((config) => {
    return config.database.loadSchema()
  }).then((schema) => {
    return schema.setPermissions('Product', {
      'find': {}
    });
  }).then((schema) => {
    res.success('OK');
  }, (err) => {
    res.error(err);
  });
});

I got ParseError { code: 105, message: 'config does not exist' } on Parse.Config.get().

How to get config and set CLP?

You can get the right config object with:

var Config = require('parse-server/lib/Config');
var config = new Config('your-app-id', '/parse'); // second param is your mount point.

This config and globalConfig are so confusing :)

@gfosco Thanks for your advice.
I got config correctly, and set permission successfully!

It would be extremely useful to have some official documentation/sample code on the recommended way to set CLPs. At the moment I can't get my migrated app to work because it relies heavily on CLPs that I don't know how to migrate.

Do CLP's migrate in general, or no?

After search i found the answer how to implement CLP.
The CLP is implemented and can be set via rest api (with master key).
the relevant file in parse-server is Schema.js

example with Parse Js SDK:

Parse._request(
        'PUT',
        'schemas/' + className,
        {className: className, fields: fields, classLevelPermissions: classLevelPermissions}
    )

the value of fields and classLevelPermissions should match the format you get by GET request:

Parse._request(
        'GET',
        'schemas',
        {}
    )

example for CLP

"classLevelPermissions": {
        "find": {
          "FVPW0vrLEB": true
        },
        "get": {
          "FVPW0vrLEB": true
        },
        "create": {},
        "update": {},
        "delete": {
          "*": true
        },
        "addField": {
          "role:isRulsMDfQ": true
        }
      }

i hope it's can helpful.

The newest version of the Parse Dashboard also lets you set CLPs, as long as you are also on the latest version of Parse Server.

Hi @gfosco, I try to use the Config class but it don't work :

const config = new Config(PARSE_APP_ID, ${PUBLIC_URL}/parse); console.log(config); // stdout : Config {} const schema = await config.database.loadSchema();

I got the error : TypeError: Cannot read property 'loadSchema' of undefined

I don't understand what change and what's wrong...

[oallouch]

For CLPs, I use the REST interface. I often use Config, but not for this one.

[brunoMaurice]

Is it possible to do something like that with the REST interface ?
if (await schema.hasClass(className)) { await schema.updateClass(className, fields); } else { await schema.addClassIfNotExists(className, fields); }

[oallouch]

Looks very doable.
Look at SchemasRouter, line 144.

[brunoMaurice]

I found a solution to access to Schema :
const schema = await Config.get(PARSE_APP_ID).database.loadSchema();

The Config class have probably change since 2016 and the class don't have the constructor but a static method get to factory the Config with all necessary property.

Thanks for you advice I will still check about the SchemasRouter for knowledge purpose (maybe a better solution for my need).
