如何更改for循环以忽略重复mealtype == 'Entrees'
我只需要它来创建1 <a href>
{% for menu in menus %}
{% if menu.mealtype == 'Entrees' %}
<li role="presentation">
<a href="#tab1" aria-controls="tab1" role="tab" data-toggle="tab">Entrees</a>
</li>
{% endif %}
{% endfor %}
全李
{% for menu in menus %}
{% if menu.show_presentation %}
<li role="presentation">
<a href="#tab1" aria-controls="tab1" role="tab" data-toggle="tab">Entrees</a>
</li>
{% endif %}
{% if menu.show_presentation %}
<li role="presentation">
<a href="#tab2" aria-controls="tab2" role="tab" data-toggle="tab">Sides</a>
</li>
{% endif %}
{% if menu.show_presentation %}
<li role="presentation">
<a href="#tab3" aria-controls="tab3" role="tab" data-toggle="tab">Mains</a>
</li>
{% endif %}
{% if menu.show_presentation %}
<li role="presentation">
<a href="#tab4" aria-controls="tab4" role="tab" data-toggle="tab">Drinks</a>
</li>
{% endif %}
{% if menu.show_presentation %}
<li role="presentation">
<a href="#tab5" aria-controls="tab2" role="tab" data-toggle="tab">Desserts</a>
</li>
{% endif %}
{% if menu.show_presentation %}
<li role="presentation">
<a href="#tab6" aria-controls="tab3" role="tab" data-toggle="tab">Specials</a>
</li>
{% endif %}
{% if menu.show_presentation %}
<li role="presentation">
<a href="#tab7" aria-controls="tab4" role="tab" data-toggle="tab">Others</a>
</li>
{% endif %}
{% endfor %}

根据评论更新以查看视图。试试这个:
show_presentation_list = []
menus_presentation = []
for menu in menus:
if menu.mealtype and menu.mealtype not in show_presentation_list:
show_presentation_list.append(menu.mealtype)
menus_presentation.append(menu)
也是你的新模板,试试这个:
{% for menu in menus_presentation %}
<li role="presentation">
<a href="#tab{{forloop.counter}}" aria-controls="tab{{forloop.counter}}" role="tab" data-toggle="tab">{{menu.mealtype}}</a>
</li>
{% endfor %}
