Python Flask Blueprint Blueprint

1. Directory structure

2. manage.py similar to Django in manage

Import Fcrm if __name__ ' __main__ ' :    fcrm.app.run (Port=8001)

3. Fcrm the following __init__.py file

 fromFlaskImportFlask from. viewsImportAccount#Import the account.py module under the Fcrm.views directory, from. viewsImportOrder#Import the order.py module under the Fcrm.views directory,app= Flask (__name__)#using blueprints, the App.route () mode is still available, paying attention to the problem of routing duplicationapp.register_blueprint (Account.account)#Register the Blueprint object account in the Views module with the appApp.register_blueprint (Order.order)#Register the Blueprint object order in the Views module with the app

3. Account and Order module under the Fcrm.view directory

 fromFlaskImportBlueprintorder= Blueprint ('Order',__name__)#creates a Blueprint object. The first parameter can be seen as the name of the Blueprint object                                         #in one app, the name cannot be duplicated with the rest of the Blueprint object name                                         #The second parameter, __name__, is used as an initialization@order. Route ('/order')#use a Blueprint object as an ' app 'deflogin ():return 'Order'

 from  flask import   Blueprint,render_templateaccount  = Blueprint ("  account  " , __name__    " /login  "  )  def   login ():  #   return ' Login '  return  render_ Template ( " login.html   ) 

Summary ideas:     1. mange.py file runs, first run the Code    2. init file in the __init__.py file below the Fcrm directory into theflask and the py file    3 under the View directory . Then Init creates the Flask    object 4. Register the module file below the views directory with the Blueprint    object 5. mange.py finally runs the Code app object in init
