使用Python操作ArangoDB的方法步骤

$ pip install pyArango

from pyArango.connection import *


# 创建连接
conn = Connection(arangoURL='http://106.54.228.237:8529', username="root", password="Letmein")
print('conn: %s' % conn)

# 创建数据库
if not conn.hasDatabase('mydb'):
  conn.createDatabase(name="mydb")

db = conn['mydb']
print('db: %s' % db)

# 创建集合
if not db.hasCollection('users'):
  db.createCollection(name='users')

collection = db['users']
print('collection: %s' % collection)

# 插入文档数据
print('collection count before insert: %s' % collection.count())
for i in range(0, 10):
  user = {
    'name': 'user_' + str(i), 
    'age': 20 + i, 
    'address': {
      'home': 'home address', 
      'office': 'office address'
    }
  }
  collection.createDocument(user).save()
print('collection count after insert: %s' % collection.count())

# 分页查询文档
print('fetchAll ...')
query = collection.fetchAll(skip=5, limit=2)
for doc in query:
  print(doc)

# 按条件查询文档
print('fetchByExample ...')
query = collection.fetchByExample({'name': 'user_5'}, batchSize=10, count=True)
for doc in query:
  print(doc)

# 使用AQL查询文档
print('query by AQL ...')
aql = "FOR user IN users FILTER user.name == @name || user.age > 25 LIMIT 5 RETURN user"
bindVars = {'name': 'user_0'}
query = db.AQLQuery(aql, rawResults=False, batchSize=1, bindVars=bindVars)
for doc in query:
  print(doc)

# 删除文档
print('collection count before delete: %s' % collection.count())
query = collection.fetchAll()
for doc in query:
  doc.delete()
print('collection count after delete: %s' % collection.count())

# 删除集合
collection.delete()
