嗨,我正在尝试用html显示{{post.post}},以前可以,但是现在不行了。显示用户名和日期,并且该帖子正在运行..但未成功显示post.post。问题出在哪里?我在下面显示了输出,并突出显示了可以指示的内容。 TIA
html:
select id, max(complaint) as complaint
from t
group by id;
models.py:
select id, complaint
from t
where complaint = 1
union all
select id, complaint
from t
where not exists (select 1 from t t2 where t2.id = t.id and t2.complaint = 1);
views.py:
{% extends 'base.html' %}
{% block body%}
<div class="container">
<h1>Home</h1>
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Submit</button>
</form>
<h2>{{ text }}</h2>
{% for post in posts %}
<h1>{{ post.post }}</h1>
<p>Posted by <b>{{ post.user.get_full_name}}</b> on {{ post.date }}</p>
{% endfor %}
</div>
{% endblock %}
输出:
class Post(models.Model):
post = models.CharField(max_length=500)
user = models.ForeignKey(User, on_delete=models.CASCADE)
date = models.DateTimeField(auto_now_add=True)

当表单无效时,您不会在发布请求的上下文数据中包含posts
,只需将其添加到上下文中即可。
args = {'form': form, 'text': text}
到
args = {'form': form, 'text': text, 'posts': Post.objects.all()}
