如何在eve中设置默认的datetime值？

Question

For example, for a key:

'joinDate' : {'type' : 'datetime'}

How can I make it automatically get posted with the current date without being explicitly given in POST method?

Answer 1

You can define an Insert Event , like this:

from datetime import datetime

"""some code omitted"""

def insert_join_date(items):
    for item in items:
        item["joinDate"] = datetime.utcnow()

app.on_insert_your_schema += insert_join_date

The previous example is based on on_insert_<resource_name>(items) and applies to a specific resource -- your_schema in this case. If this logic should by applied to all the schemas, then on_insert(resource_name, items) can be used.

Answer 2

You can use the Python datetime.datetime.now() method like so:

>>> import datetime
>>> datetime.datetime.now()
datetime.datetime(2016, 6, 30, 14, 51, 25, 977000)
