1. 切换到 virtualenv 环境
.
/pyenv/bin/activate
2. 安装pymongo

书写model
models.py,代码如下
from
flask_mongoengine
import
MongoEngine
#--
#进行配置
app.config[
'MONGODB_SETTINGS'
]
=
{
'db'
:
'the_way_to_flask'
,
'host'
:
'localhost'
,
'port'
:
27017
}
#创建mongo原型
mdb
=
MongoEngine()
mdb.init_app(app)
class
Address(mdb.Document):
name
=
mdb.StringField()
address
=
mdb.StringField()
# 查询 Address.objects(name="zhangsan").first()
# 添加 Address(name='lisi', address='lisi@gmail.com').save()
# 删除 Address.delete()
# 更新 Address.update(name="lisi@outlook.com")
书写视图
views.py,代码如下
from
models
import
Address
from
flask
import
jsonify
#--
@app
.route(
'/mdb_list'
,methods
=
[
'get'
])
def
mdb_list():
name
=
request.args.get(
'name'
)
address
=
request.args.get(
'address'
)
Addr
=
Address.objects(name
=
name,address
=
address).first()
if
not
Addr:
Address(name
=
name , address
=
address).save()
return
jsonify({
'code'
:
1
,
'message'
:
'success'
})
else
:
return
jsonify(Addr.to_json())
