Python - Flask:找不到render_template() [英] Python - Flask: render_template() not found
问题描述
你会给我一个建议,我做错了什么?谢谢
从瓶子导入Flask
从瓶子导入请求$ b $从瓶子导入render_template
app = Flask(__ name__)
@ app.route('/')
def my_form():
return render_template('my-form.html')
@ app.route('/',methods = ['POST'])
def my_form_post():
$ b $ text = request.form ['text ']
processed_text = text.upper()
return processed_text
app.debug = True
print(asdsa)
if __name__ =='__main__':
app.run()
我把文件my-form.html放到这个文件夹:C:\Python33\Lib\site-packages\flask\testsuite\template
但是当我刷新127.0.0.1:5000时,我得到

你把你的模板放在错误的地方。从Flask文档:
Flask将在模板文件夹中查找模板。所以如果你的应用程序是一个模块,那么这个文件夹就在这个模块的旁边,如果它是一个包,它实际上就在你的包里面:

I'm new in flask. I have this code: Will you give me an advice what I'm doing wrong? Thanks
from flask import Flask
from flask import request
from flask import render_template
app = Flask(__name__)
@app.route('/')
def my_form():
return render_template('my-form.html')
@app.route('/', methods=['POST'])
def my_form_post():
text = request.form['text']
processed_text = text.upper()
return processed_text
app.debug = True
print("asdsa")
if __name__ == '__main__':
app.run()
I have put file my-form.html into this folder: C:\Python33\Lib\site-packages\flask\testsuite\templates
But when I refresh the 127.0.0.1:5000 I get jinja2.exceptions.TemplateNotFound:

You put your template in the wrong place. From the Flask docs:
Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it’s a package it’s actually inside your package:
See the docs for more information: http://flask.pocoo.org/docs/quickstart/#rendering-templates
