问题描述
找不到另一个存在类似问题的帖子,我正在尝试生成一些带有flask和wtforms的复选框,此刻我已经获得了这段代码:
didn't find another post which has the similar problem, I'm trying to generate some checkboxes with flask and wtforms, at the moment I've got this piece of code:
<div class="control-group">
<p><strong>Check the enabled BRI Ports</strong></p>
<label class="checkbox inline">
{{ form.bri1(value=1) }} {{ form.bri1.label }}
</label>
<label class="checkbox inline">
{{ form.bri2(value=1) }} {{ form.bri2.label }}
</label>
<label class="checkbox inline">
{{ form.bri3(value=1) }} {{ form.bri3.label }}
</label>
<label class="checkbox inline">
{{ form.bri4(value=1) }} {{ form.bri4.label }}
</label>
</div>
到目前为止,该方法仍然有效,但是现在我尝试使用一个简单的for循环来完成此操作:
This works so far, but now I try to do this with a simple for-loop like:
<div class="control-group">
<p><strong>Check the enabled BRI Ports</strong></p>
{% for n in range(1,6) %}
<label class="checkbox inline">
{{ form.brin.label }}
{% endfor %}
</div>
我尝试过使用(),{}和{{}} ...甚至有可能吗?
I tried with (), {} and {{}} ... is this even possible?
推荐答案
尝试:
<div class="control-group">
<p><strong>Check the enabled BRI Ports</strong></p>
{% for name, field in form._fields.items() %}
{% if name != 'csrf_token' %}
<label class="checkbox inline">
{{ field(value=1) }} {{ field.label }}
</label>
{% endif %}
{% endfor %}
</div>
您可以在其中设置排序(form._fields.items()
)或条件({% if name != 'csrf_token' %}
).或者:
There you can set sorting instead form._fields.items()
or condition instead {% if name != 'csrf_token' %}
. Or:
<div class="control-group">
<p><strong>Check the enabled BRI Ports</strong></p>
{% for n in range(1,6) %}
{% if form['bri' + n|string] %}
<label class="checkbox inline">
{{ form['bri' + n|string](value=1) }} {{ form['bri' + n|string].label }}
</label>
{% endif %}
{% endfor %}
</div>
您还可以使用n.__str__()
代替过滤器n|string
.
There you can also use n.__str__()
instead filter n|string
.
