python - Flask：ValueError：从列表中解包的值太多（预期为 2）

问题描述

我正在尝试遍历GoalHours并GoalNames获取names& hours。

HTML

{% for names, hours in  GoalHours, GoalNames %}
   <input  type="submit" value="{{names}}: {{ hours }}" class="btn" name="remove" required> Hrs 
{% endfor %}

烧瓶

@blueprint.route('/goals' , methods=['GET', 'POST'])
def goals():
    goal_ = theGoal(str(flask.session['id']))
    goalNames_ = goal_['goalName']
    goalHours_ = goal_['goalHours']
    
    return render_template('/accounts/goals.html', calList = calList, GoalHours = goalHours_, GoalNames = goalNames_)

我不断得到：

ValueError: too many values to unpack (expected 2)

我尝试了从压缩到添加各种 iter 方法到导入zipAttributeError: 'Blueprint' object has no attribute 'jinja_env'的所有 Web 解决方案。非常感谢您的帮助
