Django | FilterSet没有运行查询

问题描述

我在将过滤器应用于Django中的表时遇到一些麻烦，当我应用过滤器（即单击“搜索”）时，什么都没有发生。没错没有崩溃。娜达即使url确实添加了我应用的搜索字段，URL也发生了变化，该表仍保持不变，就好像什么都没发生一样。

为简单起见，我将重命名变量，模型和所有内容的原始名称。

models.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)
    image= models.ImageField(null=True,blank=True)

class SomeStuff(models.Model):
    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):
    id = models.OnetoOneField(SomeThings,on_delete=models.PROTECT)
    character_1 = models.CharField(max_length=255,blank=False)
    character_2 = models.CharField(max_length=255,blank=False)

filters.py

import django_filters
from .models import *

class myFilter(django_filters.FilterSet):
    class Meta:
        model = SomeStuff
        fields = '__all__'
        exclude = ['stuff_2','stuff_3']

views.py

from django.shortcuts import render
from django.http import HttpResponse
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>

基本上，用户模型与SomeThings模型有关。此更高版本的模型包含另一个用于SomeStuff和OtherInfo的primary_key。

在表上，正在显示SomeStuff和OtherInfo的信息，但是，我只想使用SomeStuff中指定的变量stuff_1来过滤表。

解决方法

我认为您必须将product更改为products

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)
