Question

我是django的新手，我在检索我的allpost（我们保存在数据库中）时遇到了麻烦。所有这些都是＆＃39; allpost＆＃39;查看我在我的博客＆＃39;项目。这是代码 - views.py -

from django.shortcuts import render,redirect
from . models import Post
from django.utils import timezone
from . forms import PostForm

def blog(request):
    return render(request,'blog/blogpage.html')

def allpost(request):
    post=Post.objects.all()
    return render(request, 'blog/allpostpage.html', {'post': Post}) 
 # the posts are not displaying in this template #

def form(request):
    if request.method=='POST':
        form=PostForm(request.POST)
        if form.is_valid():
            post=form.save(commit=False)
            post.published_date=timezone.now()
            post.save()
            return redirect('allpost')
    else:
        form=PostForm()
        return render(request,'blog/formpage.html',{'form':form})

urls.py -

from django.conf.urls import url
from . import views

urlpatterns=[
    url(r'^$',views.blog,name="blog"),
    url(r'^form$',views.form,name="form"),
    url(r'^allpost$',views.allpost,name="allpost"),
]

formpage.html -

{% extends 'blog/base.html' %}
<head>
<title>form</title>
</head>
<body>
{% block content %}
<form method="POST" class="post-form">
{% csrf_token %}
{{form.as_p}}
<button type="submit" class="save-btn btn-default">save</button>

</form>
{% endblock %}
</body>
</html>

allpostpage.html -

{% extends 'blog/base.html' %}

{% block content %}

{% for post in post %}

{{post.title}}

{% endfor %}

{% endblock %}

models.py -

from django.db import models
from django.utils import timezone

class Post(models.Model):
    title=models.CharField(max_length=200)
    content=models.TextField(max_length=500)
    published_date=models.DateTimeField(blank=True)

    def publish_date(self):
        Post.published_date=timezone.now()
        Post.save()

    def __str__(self):
        return self.title

forms.py -

from django import forms
from . models import Post

class PostForm(forms.ModelForm):
    class Meta:
        model=Post
        fields=('title','content')

这些是我的代码。请检查并纠正它。再次，帖子（我们用表单保存）没有显示在＆＃39; allpostpage＆＃39; ＆＃39; allpost＆＃39;中的模板view.Thank You

在你看来allpost。而不是

return render(request, 'blog/allpostpage.html', {'post': Post})

应该是

return render(request, 'blog/allpostpage.html', {'post': post})

并在你的allpostpage.html中它应该是

{% extends 'blog/base.html' %}

{% block content %}

{% for p in post %}

{{p.title}}

{% endfor %}

{% endblock %}

这些帖子没有显示在django中保存在数据库中的内容
