    @DownPW yeah for Windows, it's just the executable as downloaded from the GitHub releases page.

    The script for Linux and Mac does the same thing, it just automatically updates the $PATH variable for you.

    If you have a custom theme that introduces custom user fields into the edit page, you might have noticed that the fields don't seem to show up on the frontend even if they're saved in the database.
    Likewise, if you have some custom data you want to maintain on a per-user basis, and you tried using user.updateProfile, you might've noticed that your fields don't seem to save.

    The reason for this behaviour is that the the user fields getter and setter are protected so that values in the user hash are not unintentionally overwritten, or that fields are retrieved that should not be.

    For example:

    nodebb-plugin-foobar saves a private user token in the user's hash. It is not meant to be retrieved. Another plugin calls user.getUsersFields() and that method naively returns everything in the user hash. The private key would then be considered leaked if it is accidentally exposed to the end user, even if unintentionally.

    Getter (retrieving user data)

    If you've saved a custom field into the user hash and you wish to retrieve it via User.getUsersFields(), you will have to explicitly whitelist it by attaching a hook listener to filter:user.whitelistFields. That plugin hook sends in { uids, whitelist }, where uids is an array of uids (requested by the calling script), and whitelist, which is an array containing user field properties.

    You can add a new entry to the whitelist thusly:


    { ... "hooks": [ { "hook": "filter:user.whitelistFields", "method": "addUserField" }, ] ... }


    library.addUserField = async ({ uids, whitelist }) => { whitelist.push('customField'); return { uids, whitelist }; };

    After doing so, a call to user.getUsersFields(uids, ['customField']); will have the customField property show up as it has been explicitly allowed.

    Setter (saving user data)

    Setting user data is comparatively simpler. We recommend using the user.updateProfile() method, as that has some sanity checks and special handling for certain fields. To allow the saving of a certain field, you will need to pass it in to the third argument of user.updateProfile():

    await User.updateProfile(callerUid, { uid, customField: 'value', }, ['customField']);

    @шЫкель-грубый said in How can I backdate topics and posts (for migration purposes)?:

    I'll also try to comment date changing in sources. I'm not familiar with JS but it looks obviously enough.

    Yes, this is probably the most direct solution. It'll get your script working with the correct timestamps, all you have to do is comment out that line in the file, and restart NodeBB.
