How to validate some fields before creation?

Help me!

This is a template you can use to report issues. You can also drag images, videos and include Preformatted text

Expected behavior

I would like to know if there is a way to validate data before creation? (mongodb)

Actual behavior

I am validating fields on my end, and intializing fields for backend computation (updatedAt, createdAt, etc)

// Create a Note
router.post('/notes', permissionMiddlewareCreator.create(), (request, response, next) => {
    // Learn what this route does here: https://docs.forestadmin.com/documentation/v/v6/reference-guide/routes/default-routes#create-a-record
    let forestAdminUser = request["user"] as IForestAdminUser;
    const {query} = request;

    const recordCreator = new RecordCreator<INote>(Notes, forestAdminUser, query);
    let record = request.body.data.attributes as INote;
    
    if (record.title === undefined || record.title === "") {
        throw new Error(TITLE_NOT_SET_ERROR);
    } else if (record.description === undefined || record.description === "") {
        throw new Error(DESCRIPTION_NOT_SET_ERROR);
    }
    
    if (record[smartFieldToStr(SmartField.ProjectID)] !== undefined) {
        if (record[smartFieldToStr(SmartField.ProjectID)] === "" || ProjectIDFromStr(record[smartFieldToStr(SmartField.ProjectID)]) === ProjectID.Undefined) {
            throw new Error(PROJECT_ID_NOT_SET_ERROR);
        } else {
            record.project_id = ProjectIDFromStr(record[smartFieldToStr(SmartField.ProjectID)]);
        }
    } else {
        throw new Error(PROJECT_ID_NOT_SET_ERROR);
    }
    
    record.created_at = getCurrentTimestampInSeconds();
    record.image_url = DEFAULT_IMAGE_ON_CREATION;
    record.is_active_in_prod = false;
    record.updated_at = getCurrentTimestampInSeconds();
    
    recordCreator.create(record as Record<string, any>).then(() => {
        response.status(200).send("Note \""+record.title+"\" created.")
    });
});

Failure Logs

I am getting this red banner: Note creation failed: unexpected error. but the record does get created if the validation is passing, which I don’t really understand :sweat_smile:

Hey @Emixam23,

of course you can. Any field that is required will be considered as required on the front too. You can also add validation (we handle, is present, min, max, minlength, maxlength)
