It means you cannot use collections on your db like this. The db = MongoEngine(app) configure your database setting. So you need define languages collections like this:

class languages(db.Document):
    name = db.StringField()
    ...

@app.route('/add', methods = ['POST'])
def add_data():
    #language = {'name':'python'}
    lang = languages(name=request.form.get('name','python'))
    lang.save()
    return jsonify({'message':"Inserted Succesfuuly"})

if you want to insert into already created languages collection, you can use pymongo:

from pymongo import MongoClient
client = MongoClient()
db = client.db_name
@app.route('/add', methods = ['POST'])
def add_data():
    #language = {'name':'pyhton'}
    db.languages.insert_one( {'name': request.form.get('name','python')})
    return jsonify({'message':"Inserted Succesfuuly"})
