python - 在 Django 中搜索几列

Question

我有一个包含几列的数据库。 我想在我的搜索中添加一个选项，不仅可以搜索像 Project 这样的一列。我也想搜索更多的列..所以搜索将查找 Project 或 ServerName 或 IP 并搜索所有列或其中的一些列。

我试过 (Project__icontains=query, ServerName__icontains=query) 但它说语法错误。

index.html:

def get(self, request):
        form = HomeForm()
        query = request.GET.get("q")
        posts = serverlist.objects.all()

        if query:
            posts = serverlist.objects.filter(Project__icontains=query)
        else:
            posts = serverlist.objects.all()
    #    else:

模型.py:

  from django.db import models


class serverlist(models.Model):
    ServerName = models.CharField(max_length = 30)
    Owner = models.CharField(max_length = 50)
    Project = models.CharField(max_length = 30)
    Description = models.CharField(max_length = 255)
    IP = models.CharField(max_length = 30)
    ILO = models.CharField(max_length = 30)
    Rack = models.CharField(max_length = 30)
    Status = models.CharField(max_length = 30)

Answer 1

你可以使用 Q objects

来自文档:

A Q object (django.db.models.Q) is an object used to encapsulate a collection of keyword arguments. These keyword arguments are specified as in “Field lookups” above.

一个例子:

posts = serverlist.objects.filter(
     Q(Project__icontains=query)|Q(ServerName__icontains=query)
)
