这是我的源代码:

<ul class="filebase">
        {% for file in finance %}
        <li class="filelist">
            <div class="file-author"><a href="http://127.0.0.1:5000/uploads/files/{{file. filename}}">{{ file.filename }}</a></div>
            <div class="file-body">Description: {{ file.description }}</div>
            <div class="file-date">Date posted: {{ moment(file.date).fromNow() }}</div>
            <div class="delete-file"><a href="{{ url_for('.delete_file', file_name={{ file.filename }} ) }}">Delete File</a></div><br>
        </li>
        {% endfor %}

起初,我的代码工作正常,我突然得到这样的错误:

TemplateSyntaxError:期望令牌':',得到'}'

这是我的追溯(如果你需要):

Traceback (most recent call last):

我想要做的是在函数的参数中传递日期，然后处理输入。这是它的功能

@HR.route('/confirm_sickLeave/<date>/<user>', methods=['GET', 'POST'])
def confirm_sickLeave(user,date):
    u = User.query.filter_by(username=user.username).first()
    print u
    us = UserStatistics.filter_by(userId=u.id).first()
    temp = us.slDates
    dates = temp.keys()
    for a in dates:
        if a == date:
            temp['date'] = True
            flash('Date Confirmed.')
            return redirect(url_for('.approval_of_leaves'))


    return redirect(url_for('.approval_of_leaves'))

现在，我的问题是我无法在我的函数中传递值。原因是我的输入中dates有斜杠 ( /)。让我演示给你看：

HTML：

{% for u in all_users %}
## Returns all the dates applied by the user (it's in dict format)
{% set user_info = u.return_sickLeaves(u.username) %}  
{% for us in user_info %}
<tr>

        <td>     {{ u.username }} …
