django pas表单在类库ListView中转换为模板

Question

我想通过带有基类ListView的搜索表单，并通过搜索查询和模板中的视图来过滤标题或内容。

models.py：

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse


class Post(models.Model):
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=100)
    content = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now)

    class Meta:
        ordering = ('-date_posted', )

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('post_detail', kwargs={'pk': self.pk})

forms.py：

from django import forms

class SearchForm(forms.Form):
    keyword = forms.CharField()

views.py：

class PostListView(ListView):
    model = Post
    template_name = 'blog/index.html'
    context_object_name = 'posts'
    paginate_by = 5
