python - django 数据库没有从我输入的详细信息中保存联系人数据
问题描述
我是 dajngo 项目的新手，我创建了一个名为“blog”的应用程序的博客。一切顺利，我坚持使用 conatct from。当我在联系人中提交详细信息并转到 djando 管理数据库时，联系人详细信息是没有保存在这里。
这是我的contact.html 代码

这是 admin.py

这是 urls.py

path("blb.html",views.blb,name='blb '),
path('<slug:slug>/', views.PostDetail.as_view(), name='post_detail'),

这是 view.py

else:
comment_form = CommentForm()
return render(request, template_name, {'post': post,

这是项目 urls.py

解决方案
首先，您不应该将 html 模板的名称放在应用程序的 urls.py 中。我的意思是这三行：
path("about.html",views.about,name='about'),
path("contact.html",views.contact,name='contact'),
path("blb.html",views.blb,name='blb '),
例如，您必须将它们替换为
path('contact/',...)
为了获得更好、更简洁的代码，最好在您的应用程序中使用表单。在您的应用程序 DIR 中创建forms.py并在您的 forms.py 中导入您的模型，例如：
from django import forms
from .models import Profile
class {model name (Table name)}(forms.ModelForm):
class Meta:
model = {model name (Table name)}
fields = '__all__'
在您的 models.py 中将 {model name (Table name)} 替换为您的模型。然后在HTML 模板中的每个输入字段中，对于名称attr ，您应该使用与 models.py 字段中使用的名称相同的名称。
在你的views.py中你应该这样做：
form = **{form name}**(request.POST or None, request.FILES)
if form.is_valid():
form.save()
return redirect('**{ somewhere :) }**')
return render(request, 'contact.html', {'form': form})
希望这个答案可以帮助你;-)
