I'm not a python expert but while your glitch <a href="https://glitch.com/edit/#!/prettymes?path=mesostic.py:17:32" rel="nofollow noreferrer">project</a> has the same code as localhost, your local machine is executing the code through a different path. In this case because there are no instructions for Glitch to start your project from <code>mesostic.py</code> it's just treating your project as a static website. (hence why the template tags are just being rendered out as text).

It might help to look at other python projects on glitch to get a sense of how to execute your <code>.py</code> file. e.g. checkout <code>start.sh</code> on <a href="https://glitch.com/edit/#!/python3-morepath" rel="nofollow noreferrer">https://glitch.com/edit/#!/python3-morepath</a>. I'm not sure but you may also need a <code>requirements.txt</code> to tell Glitch that this is a python project.

Hope this gives you a place to start debugging from

Seems like this was not a problem with earlier <a href="https://github.com/pallets/flask/issues/2127#issuecomment-360269773" rel="nofollow noreferrer">versions</a> of Flask and Python. 

<hr>

Firstly, adding the following <code>debug</code> option in the <code>server.py</code> file.

<code>
app.debug = True
</code>

Secondly, add some code as follows:

<code>
@app.after_request
def apply_kr_hello(response):
 """Adds some headers to all responses.""" 
 ...
 response.headers['Cache-Control'] = 'no-cache' 
 return response
</code>

Thirdly, do a <code>Ctrl-Shift-R</code> on the specific browser tab where your application is being rendered.

That is it! Now, when you make changes to static file, they should be reflected in your app.

I presume one might also benefit from reading <a href="https://stackabuse.com/serving-static-files-with-flask" rel="nofollow noreferrer">https://stackabuse.com/serving-static-files-with-flask</a> as well.

I have <a href="https://prettymes.glitch.me/templates" rel="nofollow noreferrer">a deployment of a tiny Flask app</a> on Glitch. It seems to be working... sort of. However, the Jinja2 template engine is clearly not working, since all Jinja2 tags are being read into the browser as text. The application, which I have up <a href="https://github.com/bronzebygold/prtty_mes" rel="nofollow noreferrer">on my GitHub page</a>, works fine on the localhost. Can I fix this somehow?

Jinja2 not work on flask/glitch.me deployment

我有的小故障。看起来很管用..。说大也大吧。但是，Jinja2模板引擎显然无法工作，因为所有的Jinja2标记都以文本的形式读取到浏览器中。这个应用程序在本地主机上工作得很好，我已经安装了。我能解决这个问题吗？
