前端之家收集整理的这篇文章主要介绍了
Flask中多APP应用以及admin后台系统,
前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
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))
