問(wèn)題描述

在同級(jí)目錄下，不明白為什么 index.html 和 視圖控制器沒(méi)有自動(dòng)綁定， 提示鴨子類型引起的，是哪里干擾了 視圖的綁定？

那這種，app和 temeplate 在同級(jí)目錄，路徑該如何寫？我 寫成 app =Flask(__name__,template_folder=’templates’)，pycharm 左側(cè)，并沒(méi)有提示 ，templates 綁定 html 的圖標(biāo)

問(wèn)題解答

默認(rèn)情況下模板是在同級(jí)目錄templates里的,你這個(gè)目錄沒(méi)有創(chuàng)建。

這個(gè)主要原因是app在定義的時(shí)候，默認(rèn)是指向templates這個(gè)目錄中的，你應(yīng)該吧index.html放到rest1的templates目錄中。或者在app=Flask(__name__, template_folder=’path’), 指定路徑http://flask.pocoo.org/docs/0... 此為Flask API文檔

Parameters: import_name – the name of the application packagestatic_url_path – can be used to specify a different path for the static files on the web. Defaults to the name of the static_folder folder.static_folder – the folder with static files that should be served at static_url_path. Defaults to the ’static’ folder in the root path of the application.template_folder – the folder that contains the templates that should be used by the application. Defaults to ’templates’ folder in the root path of the application.instance_path – An alternative instance path for the application. By default the folder ’instance’ next to the package or module is assumed to be the instance path.instance_relative_config – if set to True relative filenames for loading the config are assumed to be relative to the instance path instead of the application root.root_path – Flask by default will automatically calculate the path to the root of the application. In certain situations this cannot be achieved (for instance if the package is a Python 3 namespace package) and needs to be manually defined.

要仔細(xì)閱讀文檔，里面有寫template_folder參數(shù)讀取的目錄是以root_path為準(zhǔn)，你要理解每個(gè)參數(shù)的意義。

pycharm 設(shè)置 Mark as template folder
