如果x在< listOfModels.field>句法 [英] If x in <listOfModels.field> syntax
问题描述
我有一个类型为X的X模型,我的查询返回一个X的列表,
$ b
{%如果XY在XY%中}
测试
{%endif%}
编辑: X仍然是一个querySet(我不是迭代集)。
提前感谢
你几乎在那里您只需返回一个实际的查询器:
{%如果在XYall%中有A}
测试
{%endif%}
更新(基于评论) p>
这是不可能的模板代码,你需要做一个过滤器,Django模板语言不允许传递参数到方法。在您看来,您可以执行以下操作:
X.objects.filter(Y = A).exists()
将结果传递到模板中使用的上下文,但我不知道如何与您的确切需要。
I have a model X with a ManyToMany field Y, my query returns a list of X's,
How do I do something like:
{% if A in X.Y %}
Test
{% endif %}
EDIT: X is still a querySet (I'm not iterating the set).
Thanks in advance,
You're pretty much there. You just have to return an actual queryset:
{% if A in X.Y.all %}
Test
{% endif %}
UPDATE (based on comment)
That is not possible with template code, you need to do a filter, and the Django templating language doesn't allow passing parameters to methods. In your view, you can do:
X.objects.filter(Y=A).exists()
And pass the result into the context to be used in the template, but I'm not sure how that fits with your exact needs.
