How to use conditional if statements in Jinja 2?
提问by Arjun Kashyap
So I am new to Django and can use some help. I have used a for loop to display a list from my database. But I want to add an if statement such that, if the user input matches my database item, only then it should be displayed. Take a look :
所以我是 Django 的新手,可以使用一些帮助。我使用了 for 循环来显示我的数据库中的列表。但我想添加一个 if 语句,如果用户输入与我的数据库项目匹配,那么它才应该被显示。看一看 :
{%for inc in all_items%}
<ul>
{#I want to add an if statement here, if user input == inc_element#}
<li><p>{{inc.item_name}}<p></li>
</ul>
<hr>
{%endfor%}
I know I 'd have to use HTML forums for taking user input. But how do I match it in if statement. Help would be appreciated.
我知道我必须使用 HTML 论坛来获取用户输入。但是我如何在 if 语句中匹配它。帮助将不胜感激。
