Flask中多APP應用以及admin後臺系統

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

安裝

pip3 install flask_admin

簡單使用

from flask import Flask
from flask_admin import Admin

app = Flask(__name__)
#將app註冊到adminzhong 
admin = Admin(app)

if __name__=="mian":

    app.run()
#訪問
#127.0.0.1:5000/admin埠，會得到一個空白的頁面

將表模型註冊到admin中

#在將表註冊之前應該對app進行配置
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

#導入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))

如果有個欄位是圖片指端

#配置上傳文件的路徑
#導入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'))

#如果有個欄位要是上傳文件重寫該方法的modleView類，假設imgae_url是文件圖片的欄位
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))
