当我运行django服务器时,它显示错误但我找不到它。它显示模板语法错误
Accounting::Invoice.includes(:contact)
.only(<list_of_attributes>)
.page(params[:page].to_i)
django模板在这里:-

答案 0 :(得分:4)
Django标签被{%
和%}
包围(变量为{{
和}}
,但现在我们忽略它)。
但是在您的代码中,除了第一个{% if ... %}
语句以外,您始终在编写:
{ % endif % }
请注意{
和%
之间的空格,Django不会将其解析为Django标签。因此,您应该删除空格,以使标签显示为:
{% endif %}
因此,您应该将标签固定为:
<h2> {{ tag.name|title }} </h2>
{% if tag.startup_set.all %}
<section>
<h3>Startup {{ tag.startup_set.count|pluralize }}</h3>
<p>
Tag is associated with
{{ tag.startup_set.count }}
startup {{ tag.startup_set.count|pluralize }}
</p>
<ul>
{% for startup in tag.startup_set.all %}
<li><a href="">
{ { startup.name } }
</a></li>
{% endfor %}
</ul>
</section>
{% endif %}
{% if tag.blog_posts.all %}
<section>
<h3>Blog Post { { tag.blog_posts.count|pluralize } } </h3>
<ul>
{% for post in tag.blog_posts.all %}
<li><a href="">
{ { post.title|title } }
</a></li>
{% endfor %}
</ul>
</section>
{% endif %}
{% if not tag.startup_set.all and not tag.blog_posts.all %}
<p>This tag is not related to any content.</p>
{% endif %}
我也建议避免将查询(和其他业务逻辑)写入模板。通常,这更多是 view 的任务。
