我有一个包含12个类别的对象列表,我想获得这个列表的前3个,只显示最后一个条目这3个itens中的每一个的数据库。我究竟做错了什么?我不能拿只需要3个特定类别的最后一个项目...Flask/Mongo/Jinja - 切片一个ListField并显示数据库的最后一个条目
这是我app.py(不工作!):
# try and get experiences where mood_name is inside the mood list
try:
experiences = models.Experience.objects(mood=mood_name)
except:
abort(404)
# get the first 3 interests inside Experience
ints = models.Experience.objects.fields(slice__interest=[0,2])
interest =()
for i in ints:
interest = 'i'
# get the last experience of a specific interest
exp_highlight = models.Experience.objects(interest=interest).order_by('-timestamp')
这是我的HTML /神社(不工作):
{% for experience in experiences if experience.mood == 'Chill' %}
{% if loop.index <= 2 %}
<div class="item">
<img class="image-highlight" src="https://s3.amazonaws.com/aliceapp/{{experience.filename}}"/>
<div id="purple-small-box">
<h6>{{ experience.interest }}</h6>
</div>
<div class="small-boxes">
<h3>{{ experience.title }}</h3>
<p>{{ experience.description }}</p>
</div>
</div>
{% endif %}
{% endfor %}
