sayhello's Issues

用gunicorn部署问题

您好，最近看书部署部分，用gunicorn想部署下sayhello程序实验。

在sayhello目录下运行gunicorn sayhello:app可以正常

但是在sayhello/sayhello下运行gunicorn __init__:app 提示如下

请教原因？

Invalid package

Hi!

requirements.txt lists mako==1.1.13 as a dependency - this version simply doesn't exist on pypi. Works like a charm after changing this to any valid version.
Also, werkzeug is outdated and fails on Python3.9; updating its version to werkzeug==0.15.5 helps.

Cheers,

新手求教！！

新手求教，我复制粘贴过来一样的代码报了下面的错误

image

找了半天原因感觉似乎是bootstrap里并没有form.html

image

那个render_form在那个form.py文件里，请问这时候该怎么调用。

在pycharm上部署该项目，在view模块报错

AssertionError: View function mapping is overwriting an existing endpoint function: index
这是编译器的报错，可是整个项目中只有一个index函数，尝试了很多方法都没解决，求助。

heroku

git push heroku master 後不行在heroku 運行

add delete function

i want add delete function,but i do not know how to add submit and view function

view.py优化

messages = Message.query.order_by(Message.timestamp.desc()).all() 移动到最后的return之前。

@app.route('/', methods=['GET', 'POST'])
def index():
    form = HelloForm()
    if form.validate_on_submit():
        name = form.name.data
        body = form.body.data
        message = Message(body=body, name=name)
        db.session.add(message)
        db.session.commit()
        flash('Your message have been sent to the world!')
        return redirect(url_for('index'))
    messages = Message.query.order_by(Message.timestamp.desc()).all()
    return render_template('index.html', form=form, messages=messages)

sqlalchemy报错

作者你好，我fork了 您的文件，在根目录下写了一个start.py

from sayhello import app
import flask
FLASK_DEBUG = 1
if __name__ == '__main__':
    app.run(debug=True)

执行后报错为：sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) no such table: message。
烦请您指点一下。

7.4最后一句中的疑问

原描述是：

作为替代，你也可以加载Bootstrap提供的合集包文件bootstrap.bundle.min.css

应该是：
bootstrap.bundle.min.css → bootstrap.bundle.min.js

pipenv install --dev 执行之后 所有的包不能安装 请问这是什么原因呢

一直都是按照教程走的

clone下来 进入项目 安装依赖的时候就这样

直接clone下代码，在pycharm运行项目的时候，就报了错误，会不会是环境配置的问题，，从邮件那篇开始就总有traceback
