python - 如何使用 WTForms 制作具有唯一 id 的多个复选框，以便可以将其存储在架子上？

Question

如何使用 WTForms 制作多个复选框并将其呈现到我的 html 页面？这就是我使用 WTForms 想到的，但我被告知通过使用 Boolean(True,False) 它将仅适用于一个复选框而不是多个复选框。我如何将选定的复选框附加到字典中有一个唯一的 ID 吗？

我对 python、flask 和 WTForms 很陌生。感谢您抽出时间来帮助我。给我一些建议/指南来帮助我解决这个问题也很好。

Answer 1

如果有帮助，请告诉我。最后，返回一个字典(数据)，其中包含选中的复选框的名称。

flask 代码:

@app.route('/index/', methods=['POST', 'GET'])
def index():
    weekdays = ['Mon', 'Tue', 'Wed', 'Thur', 'Fri', 'Sat', 'Sun']
    timeslots = ['8AM', '9AM', '10AM', '11AM', '12PM', '13PM', '14PM','15PM','16PM','17PM','18PM']

    if request.method == "POST":
        data = dict((key, request.form.getlist(key) if len(
            request.form.getlist(key)) > 1 else request.form.getlist(key)[0])
            for key in request.form.keys())
        print (data) # do whatever you want with this data dict. Store it, flash messages, etc.

    return render_template('index.html',
       weekdays = weekdays,
       timeslots = timeslots,
       )

模板

<form method = "post" action = "">
  <table class="table table-bordered">
    <thead>
      {% for weekday in weekdays %}
      <tr>
        <th> {{ weekday }} </th>
          {% for timeslot in timeslots %}
            <td><input id="{{ weekday+timeslot }}" type="checkbox" name="{{ weekday+timeslot }}">{{ timeslot }}</td>
          {% endfor %}
      </tr>
      {% endfor %}
    </thead>
  </table>
  <div class="form-group col-md-1">
    <input type="submit" value="Submit" class="btn btn-info"/>
  </div>
</form>
