因此,我在我的网站上有一个供稿,其中列出了最近制定的所有新“建议”。 这些在我的html模板的jinja2循环中列出。问题是,我在每个提案下都有评分按钮,我希望能够获得用户在python中单击的评分,然后将其发送到数据库。 但是我还是个初学者,我真的不知道该怎么做。
这就是我的html模板中的内容:
{% for proposition in propositions %}
<div class="feed_propBox"> <!--prop Box: Begin-->
<form method="POST" action="rate">
<p id="titre" name="titre" value="{{proposition.title}}">{{ proposition.title }}</p>
<p id="perso" name="perso">{{ proposition.date }}</p>
<p id="content" name="content">{{ proposition.content }}</p>
<div class="ratingBlock">
<button type="submit" class="mThree ratingButton" id="m3" name="rate" value="m3">-3</button>
<button type="submit" class="mTwo ratingButton" id="m2" name="rate" value="m2">-2</button>
<button type="submit" class="mOne ratingButton" id="m1" name="rate" value="m1">-1</button>
<button type="submit" class="zero ratingButton" id="z" name="rate" value="z">0</button>
<button type="submit" class="pOne ratingButton" id="p1" name="rate" value="p1">1</button>
<button type="submit" class="pTwo ratingButton" id="p2" name="rate" value="p2">2</button>
<button type="submit" class="pThree ratingButton" id="p3" name="rate" value="p3">3</button>
</div>
</form>
</div> <!--prop Box: End-->
{% endfor %}
在我的python views.py中,我将其作为供稿使用:
@bp.route('/rate', methods=['POST','GET'])
def rate():
if request.method == 'POST':
note_list = ["m3", "m2", "m1", "z", "p1", "p2", "p3"]
for i in note_list:
titre = request.form["titre"]
note = request.form['rate']
if note == i:
note = note_list.index(i)
client.POSTS.rating.insert_one({"title" : titre, "rate" : note})
return redirect(url_for('.proposer'))
但是,单击评分按钮时,我会收到此错误:

无论如何,我认为问题可能仅来自“标题”,但我也不知道该如何解决...
顺便说一句,你们知道如何将值附加到json文档中的数组吗?使用python和mongodb运算符:/
非常感谢:)
答案 0 :(得分:0)
我认为错误来自此行:
titre = request.form["titre"]
您可能在titre
对象中没有request.form
键。
为了调试此问题,我建议在循环中添加一个print request.form
,以便您可以看到对象的结构。
此外,如果request.form["titre"]
为空,则可能是因为您在value
元素上设置了<p>
属性,而HTML中是不允许的。
根据this page value
属性无法在<p>
元素上设置。尝试切换到<input>
元素。

好吧,前一段时间找到了解决方法
如果可以帮助任何人:
只需使用request.form.get('')
而不是request.form['']
以及带有隐藏属性的输入,以获取proposition.title的值。
