Saving and updating nested documents with MongoEngine

I want to implement this structural model to store my data on Mongodb with MongoEngine on flask:

skills = [{"asm":"Assembly",
           "flag":False,
          "date": datetime},
          {"java":"Java",
           "flag":False,
           "date": datetime}]

So I don't know how I can declare and update this kind of structure. For updating one object I used:

User.objects(skills=form.skills.data).update_one()

However, I don't know how to update more fields in one shot. I tried with the code below but it doesn’t work.

now = datetime.now()
 User.objects(skills=form.skills).update_one(set__skills = ({'ruby':'Ruby'}, {'flag':'true'},{'date':now}))

What kind of fields should I declare on forms.py?

For what I understood, you need a a nested document (skills) into another (who refers to User in this case). For doing something like this you don't have to update atomically a field but append values to the subdocument and the save everything. Tryin' to follow your example, in your case should do something like this:

user = User.objects(email=current_user.email).get()

To get the BaseQuery that refers to user X through a certain query filter, in my example the email of the current logged user

user.kskills.append(SubDocumentClass(skillName="name_of_the_skill", status=True, date=datetime.now()))

For append a collection to the subdocument list. (I've appended your field)

user.save()

To save everything
