Assuming, var friend = { firstName: ‘Harry’, lastName: ‘Potter’ }; There are two options you have: Update the model in-memory, and save (plain javascript array.push): or I always try and go for the first option when possible, because it’ll respect more of the benefits that mongoose gives you (hooks, validation, etc.).

Unfortunately, MongoDB doesn’t provide this option for any of the commonly needed types such as str, decimal or datetime: http://api.mongodb.org/python/current/tutorial.html#a-note-on-unicode-strings http://api.mongodb.org/python/current/faq.html#how-can-i-store-decimal-decimal-instances http://api.mongodb.org/python/current/faq.html#how-can-i-save-a-datetime-date-instance Having eliminated Mongo options, that leaves writing Python code to do the conversion after the data is retrieved. … Read more
MongoDB needs a folder to store the database. Create a C:\data\db\ directory: and then start MongoDB: Sometimes C:\data\db folder already exists due to previous installation. So if for this reason mongod.exe does not work, you may delete all the contents from C:\data\db folder and execute mongod.exeagain.

Most probably unit mongodb.service is masked. Use following command to unmask it. sudo systemctl unmask mongod and re-run sudo service mongod start
The enums here are basically String objects. Change the enum line to enum: [‘NEW’, ‘STATUS’] instead. You have a typo there with your quotation marks.
You created the directory in the wrong place /data/db means that it’s directly under the ‘/’ root directory, whereas you created ‘data/db’ (without the leading /) probably just inside another directory, such as the ‘/root’ homedirectory. You need to create this directory as root Either you need to use sudo , e.g. sudo mkdir -p /data/db Or you … Read more
