如何获取包含特定字符串的对象

Question

I want to retrieve objects that contain a specific string in their CharField.
In normal Python without Django, I can do this to check:

if "something" in string:
   pass

However, I don't know how to do so using .filter() in Django:

posts = Post.objects.filter(field = "string") # how can I do something like 'in' here?

I don't just want to get objects that have exactly the value as "string".

Please teach me how to retrieve objects that contain a specific string in Django using .filter() .

Answer 1

You can use contains . This will do case-sensitive containment test .

Post.objects.filter(field__contains='string')

This will generate the following SQL query.

SELECT ... WHERE field LIKE '%string%'

See field lookups for more information.

Answer 2

posts = Post.objects.filter(field__icontains = "string")
