Python Django |过滤器集未运行查询

在django中将筛选器应用于表时遇到了一些问题，当我应用筛选器（即单击“搜索”）时，什么都没有发生。没有错误。没有撞车。娜达。即使url在添加我应用的搜索字段时发生了更改，该表仍保持不变，就好像什么都没有发生一样

为了简单起见，我将重命名变量、模型和所有东西的原始名称

型号.py

from django.db import models
from other_app.models import CustomUser
from another_app.models import OtherModel

class SomeThings(models.Model):
    # default User was replaced with an AbstractUser model
    user = models.OneToOneField(CustomUser, on_delete=models.PROTECT) 
    id = models.CharField(max_length=10,primary_key=True)
    thing_1= models.PositiveIntegerField(blank=False)
    thing_2= models.PositiveIntegerField(blank=False)

    id = models.OneToOneField(SomeThings, on_delete=models.PROTECT)
    stuff_1 = models.CharField(max_length=255, blank=False)
    stuff_2 = models.CharField(max_length=255, blank=False)
    stuff_3 = models.ForeignKey(OtherModel, on_delete=models.PROTECT, null=True)

class OtherInfo(models.Model):

    character_1 = models.CharField(max_length=255, blank=False)
    character_2 = models.CharField(max_length=255, blank=False)

视图.py

from another_app.models import OtherModel

class SomeThings(models.Model):
    # default User was replaced with an AbstractUser model
    user = models.OneToOneField(CustomUser, on_delete=models.PROTECT) 
    id = models.CharField(max_length=10,primary_key=True)

import django_filters

class myFilter(django_filters.FilterSet):
    class Meta:
        model = SomeStuff

        exclude = ['stuff_2','stuff_3']

from django.shortcuts import render

from .filters import myFilter

def search(request):
    products = SomeStuff.objects.all()

    filter= myFilter(request.GET,queryset=products)
    product= filter.qs

    context = {'products':products,'filter':filter,}
    return render(request, 'search.html', context)

search.html

{% load static %}

... some html stuff ...

<form method="get">
    {{ filter.form }}
    <button class="btn btn-primary" type="submit">
        Search
    </button>
</form>

<table>
    <thead>
        <tr>
            <th>Stuff 1</th>
            <th>Object 1</th>
            <th>Object 2</th>
        </tr>
    </thead>
    <tbody>
        {% for product in products %}
            <tr>
                <td>{{product.stuff_1}}</td>
                <td>{{product.id.otherinfo.character_1}}</td>
                <td>{{product.id.otherinfo.character_2}}</td>
            </tr>
        {% endfor %}
    </tbody>
</table>

{%load static%}
... 一些html的东西。。。
{{filter.form}
搜寻
材料1
对象1
对象2
{products%中产品的%s}
{{product.stuff_1}}
{{product.id.otherinfo.character_1}
{{product.id.otherinfo.character_2}
{%endfor%}

基本上，用户模型是与模型相关的。后一个模型包含另一个主键，用于something和OtherInfo

在表上，显示来自SomeStuff和OtherInfo的信息，但是，我只想使用SomeStuff中指定的变量stuff_1筛选表。

我认为您必须使用

产品更改
产品

def search(request):
    products = SomeStuff.objects.all()

    filter= myFilter(request.GET,queryset=products)
    products= filter.qs  #this should be products instead of product

    context = {'products':products,'filter':filter,}
    return render(request, 'search.html', context)

    context = {'products':products,'filter':filter,}

我真傻！就这样。你介意解释一下原因吗？过滤器会更新你在上下文中传递的查询集，如果没有搜索查询，它会传递原始查询集。这真的很有帮助！我真傻！就这样。你介意解释一下原因吗？过滤器会更新你在上下文中传递的查询集，如果没有搜索查询，它会传递原始查询集。这真的很有帮助！
