如何解决尽管从服务器获得 200 OK，但 django 表单中的数据并未发布在 Postgressql 数据库中
我正在使用 Django 3.0 版为我学校的各个部门创建一个注册应用程序。我已将表单连接到模型，并且模型存储在 postgressql 数据库中。在我使用 python manage.py runserver 启动服务器并完成表单并单击保存后，表单刷新并从通过终端访问的服务器获得 OK HTTP Code 200，但是当我使用 pg 管理界面查询 postgressql 数据库时数据尚未存储。谁能看到我哪里出错了？这个过程以前有效，我不确定数据是否只是存储在另一个表中。如果可以，请帮忙。
这是我的 base.html 文件：
{% load static %}
<!DOCTYPE html>
<html>
<head>
<title>Signup Prototype</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css" integrity="sha384-TX8t27EcRE3e/ihU7zmQxVncDAy5uIKz4rEkgIXeMed4M0jlfIDPvg6uqKI2xXr2" crossorigin="anonymous">

</script>
{{form.media}}
</head>
<body>
<header class="page-header">
<div class="container">

<main class="content container">
<div class="row">
<div class="col">
{% block content %}
{% endblock %}
</div>
</div>
</main>
</body>
</html>
这是我的engineering.html文件，显示表单
<html>
{% extends 'base.html' %}
{% load static %}
{% block content %}
<h2>Engineering</h2>
<form method="POST" class="engineering-form">{% csrf_token %}
{{ form.as_p }}
<button type="submit" class="save btn btn-default">Save</button>
</form>
{% endblock %}
<html>
这是我的 .views 文件：
from django.shortcuts import render
from .forms import Engineering
def engineering(request):
form = Engineering()
return render(request,'my_app/engineering.html',{'form': form})
这是我的表格
class Engineering(forms.ModelForm):
name = forms.CharField(label="Name")
etoken_user = forms.BooleanField(required = False,label="Etoken Use")
mfa_use = forms.BooleanField(required = False,label="MFA Use")
usage_type = forms.CharField(label="Usage Type")
email = forms.EmailField(label="Email")
user_id = forms.CharField(label="USERid")
date = forms.DateTimeField(label="Date") # date just time stamp the date they are using
class Meta: #tells django which model should be used to create the form
model = Engineering
fields = ('name','etoken_user','mfa_use','usage_type','email','user_id','date')
widgets = {
'datetime':DateTimeWidget(attrs={'id':'UTC' },usel10n=True,bootstrap_version=4)
}
这是模型
class Engineering(models.Model):
user_name = models.CharField(max_length = 100)
etoken_use = models.BooleanField()
mfa_use = models.BooleanField()
usage_type = models.CharField(max_length = 100)
date_recorded = models.DateTimeField(auto_now_add = True)
email = models.EmailField(max_length = 150)
user_id = models.CharField(max_length = 20)
解决方法
是的，因为您的视图不会对 POST 上的数据执行任何操作。
见https://docs.djangoproject.com/en/3.0/topics/forms/#the-view
,正如前面的回答所指出的，您没有对从视图中的表单发布的数据执行任何操作。
from django.shortcuts import render
from .forms import Engineering
def engineering(request):
form = Engineering()
if request.method == 'POST':
form = Engineering(request.POST)
if form.is_valid():
form.save()
# probably a redirect over here.
return render(request,'my_app/engineering.html',{'form': form})
