我对 Django 很陌生，还在学习它，但我必须创建类似 medium.com 的东西。我想根据用户的兴趣向他们展示帖子。我在注册表单中添加了一个带有复选框的兴趣字段。当然，我在 Post 模型中添加了一个类别。那么，我如何才能显示（仅限登录用户）他们感兴趣的出版物？这是我在帖子应用程序中的 models.py 文件
from django.db import models
from django.utils import timezone
from django.urls import reverse
# Create your models here.
class Post(models.Model):
CATEGORY = (
('sport', 'Sport'),
('science', 'Science'),
('it', 'IT'),
('art', "Art"),
)
title = models.CharField(verbose_name="Title for publication", max_length=50)
category = models.CharField(verbose_name="Category", choices=CATEGORY, max_length=50)
author = models.ForeignKey("accounts.User", verbose_name="Author:", on_delete=models.CASCADE)
body = models.TextField(verbose_name="Body for publication")
pub_date = models.DateTimeField(verbose_name="Date:", auto_now_add=True)
def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
def get_absolute_url(self):
return reverse("post_detail", kwargs={"pk": self.pk})
def __str__(self):
return self.title
这是我在帖子应用程序中的 vies.py 文件
from django.views.generic import ListView, DetailView
from django.views.generic.edit import CreateView, UpdateView, DeleteView
from .models import Post
from django.urls import reverse_lazy
class PostListView(ListView):
model = Post
template_name = "index.html"
def get_queryset(self):
return Post.objects.order_by('-pub_date')
class PostDetailView(DetailView):
model = Post
template_name = "./posts/post_detail.html"
class PostCreateView(CreateView):
model = Post
template_name = "./posts/new_post.html"
fields = '__all__'
class PostUpdateView(UpdateView):
model = Post
template_name = "./posts/update_post.html"
fields = ['body', 'title', 'category']
class PostDeleteView(DeleteView):
model = Post
template_name = "./posts/delete_post.html"
success_url = reverse_lazy('index')
class SportPostListView(ListView):
model = Post
template_name = "./posts/sports.html"
class ITPostListView(ListView):
model = Post
template_name = "./posts/it.html"
class SciencePostListView(ListView):
model = Post
template_name = "./posts/ilm-fan.html"
class ArtPostListView(ListView):
model = Post
template_name = "./posts/sanat.html"
这是我的 index.html 文件
{% extends 'base.html' %}
{% block content %}
{% if object_list %}
{% for post in object_list %}
<h1>{{ post.title }}</h1>
<p>{{ post.pub_date }}</p>
<p>{{ post.author }}</p>
<p>{{ post.body }}</p>
<p>{{ post.category }}</p>
{% endfor %}
{% else %}
<p>No posts are available.</p>
{% endif %}
{% endblock content %}
这是我在帐户应用程序中的 forms.py 文件
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
from django.db import models
from django import forms
class SignUpForm(UserCreationForm):
INTERESTS = (
('sport', 'Sport'),
('science', 'Science'),
('it', 'IT'),
('art', "Art"),
)
username = forms.CharField(max_length=128, required=True)
email = models.EmailField(verbose_name='emailingiz', unique=True, default='')
first_name = forms.CharField(max_length=128, required=True)
last_name = forms.CharField(max_length=128, required=True)
interests = forms.MultipleChoiceField(required=True, widget=forms.CheckboxSelectMultiple, choices=INTERESTS)
USERNAME_FIELD = 'email'
class Meta:
model = User
fields = ('first_name', 'last_name', 'username', 'email', 'interests', 'password1', 'password2')
最后是帐户应用程序中的这个 views.py 文件
from django.urls import reverse_lazy
from django.views.generic import CreateView
from .forms import SignUpForm
class SignUpView(CreateView):
form_class = SignUpForm
success_url = reverse_lazy('login')
template_name = 'signup.html'
我不知道该怎么做，但我知道我必须在帖子应用程序的 views.py 文件中做一些事情，但是，我不知道该怎么做。如果您能帮助我，将不胜感激。
