Flask中多APP应用以及admin后台系统

一.多APP

from werkzeug.wsgi import DispatcherMiddleware

from werkzeug.serving import run_simple

from flask import Flask, current_app

app1 = Flask('app01')

app2 = Flask('app02')

@app1.route('/index')

def index():

    return "app01"

@app2.route('/index2')

def index2():

    return "app2"

# http://localhost:5000/index

# http:/localhost:5000/sec/index2

dm = DispatcherMiddleware(app1, {

    '/sec': app2,

})

if __name__ == "__main__":

    run_simple('localhost', 5000, dm)

二.flask-admin

安装

pip3 install flask_admin

简单使用

from flask import Flask

from flask_admin import Admin

app = Flask(__name__)

#将app注册到adminzhong

admin = Admin(app)

if __name__=="mian":

	app.run()

#访问

#127.0.0.1:5000/admin端口，会得到一个空白的页面

将表模型注册到admin中

#在将表注册之前应该对app进行配置

SQLALCHEMY_DATABASE_URI = "mysql+pymysql://root:@127.0.0.1:3307/py9api?charset=utf8mb4"

SQLALCHEMY_POOL_SIZE = 5

SQLALCHEMY_POOL_TIMEOUT = 30

SQLALCHEMY_POOL_RECYCLE = -1

#导入models文件的中的表模型

from flask_admin.contrib.sqla import ModelView

from api.models import Stock,Product,Images,Category,Wxuser,Banner

admin.add_view(ModelView(Stock, db.session))

admin.add_view(ModelView(Product, db.session))

admin.add_view(ModelView(Category, db.session))

如果有个字段是图片指端

#配置上传文件的路径

#导入from flask_admin.contrib.fileadmin import FileAdmin

from flask_admin.contrib.fileadmin import FileAdmin,form

file_path = op.join(op.dirname(__file__), 'static')

admin = Admin(app)

admin.add_view(FileAdmin(file_path, '/static/', name='文件'))

#如果有个字段要是上传文件重写该方法的modleView类，假设imgae_url是文件图片的字段

class ImagesView(ModelView):

    form_extra_fields = {

        'image_url': form.ImageUploadField('Image',

                                          base_path=file_path,

                                          relative_path='uploadFile/'

                                          )

    }

admin.add_view(ImagesView(Images, db.session))
