在django中使用搜索词进行自定义排序

from django import forms

class SearchForm(forms.Form):
    search_term = forms.CharField(label='Search')
    sort_by = forms.ChoiceField(label='Sort By', choices=(
        ('name', 'Name'),
        ('date', 'Date'),
        ('rating', 'Rating'),
    ))

from django.shortcuts import render
from .forms import SearchForm
from .models import Book

def search_books(request):
    form = SearchForm(request.GET)
    if form.is_valid():
        search_term = form.cleaned_data['search_term']
        sort_by = form.cleaned_data['sort_by']
        
        # 构建查询
        books = Book.objects.filter(name__icontains=search_term)
        
        # 根据排序字段进行排序
        if sort_by == 'name':
            books = books.order_by('name')
        elif sort_by == 'date':
            books = books.order_by('date')
        elif sort_by == 'rating':
            books = books.order_by('rating')
        
        return render(request, 'search_results.html', {'books': books})
    
    return render(request, 'search_form.html', {'form': form})

<form method="GET" action="{% url 'search_books' %}">
  {{ form.as_p }}
  <button type="submit">Search</button>
</form>
