英文:
Queryset for search by username and display_name In Django Rest Framework
问题
-
我试图通过他们的用户名和显示名称来搜索用户。
-
我已经使用了这个开始匹配的方法。
search_obj = User.objects.exclude(user_uuid=token_user_uuid).filter(Q(display_name__istartswith=search_name)| Q(username__istartswith=search_name)).order_by('-created_on')[:10]
我得到了与我想要的答案相同的答案，但问题是如果显示名称是William Welch，而我搜索Welch，它应该返回该用户，但它没有返回该用户。
情况。用户名：123William显示名称：William Welch如果搜索名称为12，则匹配如果搜索名称为23w，则不匹配如果搜索名称为Wil，则匹配如果搜索名称为Welc，则匹配如果搜索名称为elch，则不匹配
英文:
I'm trying to search users by their usernames and display names.
- I have used that for the starting match.
search_obj = User.objects.exclude(user_uuid=token_user_uuid).filter(Q(display_name__istartswith=search_name)| Q(username__istartswith=search_name)).order_by('-created_on')[:10]
I get the answer same as I want but the problem is if the display name is William Welch and I search for Welch It should return that user also, but it does not return that user.
cases.username: 123Williamdisplay name: William Welchif search_name 12 then matchif search_name 23w then not matchif search_name Wil then matchif search_name Welc then matchif search_name elch then not match

你可以使用__icontains <sup>[Django文档]</sup>进行子字符串搜索：
from django.db.models import Qsearch_obj = (User.objects.exclude(user_uuid=token_user_uuid).filter(display_name<b>__icontains</b>=search_name,username<b>__icontains</b>=search_name,_connector=Q.OR,).order_by('-created_on')[:10])
如果你想搜索以特定词开头的内容，可以使用**__iregex**查找 <sup>[Django文档]</sup>来使用正则表达式：
import refrom django.db.models import Qrgx = fr'\y{re.escape(search_name)}'search_obj = (User.objects.exclude(user_uuid=token_user_uuid).filter(display_name<b>__iregex=rgx</b>,username<b>__iregex=rgs</b>,_connector=Q.OR,).order_by('-created_on')[:10])
英文:
You can search with __icontains <sup>[Django-doc]</sup> to look for a substring instead:
<pre><code>from django.db.models import Q
search_obj = (
User.objects.exclude(user_uuid=token_user_uuid)
.filter(
display_name<b>__icontains</b>=search_name,
username<b>__icontains</b>=search_name,
_connector=Q.OR,
)
.order_by('-created_on')[:10]
)</code></pre>
If you want to search for starting words, you can work with a regex with the __iregex lookup <sup>[Django-doc]</sup>:
<pre><code>import re
from django.db.models import Q
rgx = fr'\y{re.escape(search_name)}'
search_obj = (
User.objects.exclude(user_uuid=token_user_uuid)
.filter(
display_name<b>__iregex=rgx</b>,
username<b>__iregex=rgs</b>,
_connector=Q.OR,
)
.order_by('-created_on')[:10]
)</code></pre>
