Django：表单未保存到数据库

Posted 2023-05-07

【中文标题】Django：表单未保存到数据库

【英文标题】：Django: Form is not saving to database

【发布时间】：2016-01-12 23:36:19

【问题描述】：

我在这里看到过类似类型的问题，但我仍然无法解决我的问题。当我在视图中保存 PhotographerProfileForm 时，表单会正确呈现，但在单击更新/提交后实际上并没有保存任何内容。

也没有显示错误。

我现在拥有的是预先填充的字段，我希望能够将这些字段保存在数据库中，但没有任何反应，目前您只能从管理面板更新它。

models.py

from __future__ import unicode_literals
from django.contrib.auth.models import User

from django.db import models


# Create your models here.
class PhotographerProfile(models.Model):
    user = models.OneToOneField(User)
    location = models.CharField(max_length=200)
    bio = models.TextField(max_length=500)

    def __str__(self):
        return self.user.username

User.profile = property(lambda u: PhotographerProfile.objects.get_or_create(user=u)[0])


from django.db.models.signals import post_save
from django.dispatch import receiver

@receiver(post_save, sender=User)
def create_profile(sender,instance,created,**kwargs):
    if created:
        profile, new = PhotographerProfile.objects.get_or_create(user=instance)

urls.py

urlpatterns = [
url(r'^profile/$', 'photoprofile.views.photographer_profile', name = 'photographer_profile'),
url(r'^profile/portfolio/$', 'photoprofile.views.photographer_portfolio', name='photographer_portfolio'),

views.py

def photographer_profile(request):
    photographerProfile = PhotographerProfile.objects.get(user=request.user)
    form = PhotographerProfileForm(initial='bio':photographerProfile.bio,     'location':photographerProfile.location)#This means you can prepoulate it
    return render_to_response('photographerprofile.html','form':form,  RequestContext(request))

    if request.method == 'POST':
        form = PhotographerProfileForm(request.POST, instance = request.user.profile,)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('/accounts/profile')

    else:
        user = request.user
        profile = user.profile
        form = PhotographerProfileForm()

    return render(request, 'photographerprofile.html', 'form':form)

def photographer_portfolio(request):
    photographerProfile = PhotographerProfile.objects.get(user=request.user)
    return render_to_response('photographerportfolio.html', 'photographerProfile':photographerProfile, RequestContext(request))

forms.py

class PhotographerProfileForm(forms.ModelForm):

class Meta:
    model = PhotographerProfile
    exclude = ('user',)

photographerprofile.html

% extends 'base.html' %
% load crispy_forms_tags %

% block content %

<h2> Profile</h2>

% for field in form %
 field.error

    <p>Click <a href='/accounts/profile/portfolio/'>here</a> to view portfolio.    </p>

</form>

【参考方案1】：

在处理表单之前，您在视图的第三行返回。删除该行。

【讨论】：

返回 render_to_response('photographerprofile.html','form':form, RequestContext(request)) 。这条线？什么都没有发生

是的，完全删除该行。

是的，我已将其删除。它似乎没有做任何事情，它还删除了预先填充的数据。

尝试移动线来替换最终渲染。在return render_to_response('photographerprofile.html','form':form, RequestContext(request)) 之后移动第一个render_to_response return render_to_response('photographerprofile.html','form':form, RequestContext(request))。然后完全删除 return render_to_response('photographerprofile.html','form':form, RequestContext(request)) 您并没有通过完全删除它来提供 RequestContext。也请给我一分钟，我会检查其余的代码。

@AaronLayfield 抱歉，只是想知道您是否有机会查看它。花了一整天的时间重新启动，并出现同样的问题。我无法保存表单中的数据
