flask分離路由，前面是最笨的方法，最好的辦法是使用藍圖

from management import view
if __name__ == '__main__':
    view.run()

from flask import Blueprint, render_template, request

admin = Blueprint('admin', __name__)


@admin.route('/index')
def index():
    return render_template('admin/adminmanagement.html')


@admin.route('/add')
def add():
    return 'admin_add'


@admin.route('/show')
def show():
    return 'admin_show'

from flask import Blueprint, render_template, redirect

user = Blueprint('user', __name__)


@user.route('/index')
def index():
    return 'nice'
    # return render_template('user/seeHello.html')


@user.route('/add')
def add():
    return 'user_add'


@user.route('/show')
def show():
    return 'user_show'

from flask import Flask

# 這種寫法也可
# from management.admin.admin import admin
# from management.user.user import user

# 這里是你python的語法不足，所以你想了一宿。。。，不是框架的問題
# from admin import admin 是錯誤寫法，編譯器找不到這個函數

# 這里是用的相對路徑
from .admin.admin import admin
from .user.user import user


app = Flask(__name__)

app.register_blueprint(admin, url_prefix='/admin')
app.register_blueprint(user, url_prefix='/user')


def run():
  app.run(debug=True)
