Hey I am trying to reverse engineer how the user creation process works from the front end. When i click the button save, i see:

POST /content-manager/collection-types/plugins::users-permissions.user

My need is to be able to limit the number of total users of a certain type.
Now, i tried copying the folder onto the extensions folder of strapi but it spit out an error. Probably i am totally off road, but how would go about setting up this users limit?

Thanks

I’ve done a bit of further research and it seems that the file is /node_modules/strapi-plugin-content-manager/controllers/collection-types.js, in particular:

  async create(ctx) {
    const { userAbility, user } = ctx.state;
    const { model } = ctx.params;
    const { body } = ctx.request;
    strapi.log.debug(model);
    strapi.log.debug(body);
    const entityManager = getService('entity-manager');
    const permissionChecker = getService('permission-checker').create({ userAbility, model });

    if (permissionChecker.cannot.create()) {
      return ctx.forbidden();
    }

    const pickWritables = pickWritableAttributes({ model });
    const pickPermittedFields = permissionChecker.sanitizeCreateInput;
    const setCreator = setCreatorFields({ user });

    const sanitizeFn = pipe([pickWritables, pickPermittedFields, setCreator]);

    await wrapBadRequest(async () => {
      const entity = await entityManager.create(sanitizeFn(body), model);
      ctx.body = permissionChecker.sanitizeOutput(entity);

      await strapi.telemetry.send('didCreateFirstContentTypeEntry', { model });
    })();
  },

However:

  1. strapi.log.debug() does not show anything
  2. seems kinda awkward, to me, to control what content can be limited
