在烧瓶上执行 py 脚本的问题

Question

感谢您的关注！

我在使用烧瓶执行 .py 脚本时遇到问题。 当我在调用中将所有东西都放在一个“def”中时，我可以将带有 dict 的值直接返回到烧瓶中，然后返回 HTML 页面。但是当我在我的脚本中使用多个'def'时 - 我在外面有'无'。对不起我的英语不好:)

routes.py

import calc_ttv as ct

...

@app.route('/calculate', methods=['GET', 'POST'])

    undertitle = 'online web app'
    date_var = request.form['datepicker-input-line']
    if date_var == '':
        flash('Use calendar first!')
        return render_template('calculate_interface.html', undertitle=undertitle)
    time_var = request.form['timepicker-input-line']
    gender_var = request.form['gender-input-line']
    suntime_var = request.form['timepicker-sunrise-input-line']
    naksh_var = request.form['nakshatra-input-line']
    fday = date_var[0:2]
    fmonth = date_var[3:5]
    fyear = date_var[6:10]
    fhour = time_var[0:2]
    fminute = time_var[3:5]
    if gender_var == 'Male':
        fgender = 1
    else:
        fgender = 2
    fnakshatra = naksh_var
    fsunhour = suntime_var[0:2]
    fsunminute = suntime_var[3:5]

这毕竟是我得到的：

Answer 1

函数calculateDate 没有return 语句，因此函数calculate（在routes.py 中）中的result 变量总是None。

修改 calc_ttv.py 中的calculateDate 以返回您的计算结果：

return cttvcl.calculateTime()
