Python Django表单未保存到数据库

我在网站上搜索了一个解决方案，很多相关的问题，但是没有直接的回应。我的项目中有3个应用程序，其中2个运行得很好，除了这个应用程序，它没有写入数据库

是的，其他两个应用程序写入postgres数据库，我可以查看该表，但这会返回空行，我看不出有任何问题。我希望有人能帮助我，看看下面我的模型，表单和View.py

我的观点.py

from django.shortcuts import render, redirect
from .forms import EngForm

def EngineerList(request):
    return render(request, "Engineers/elist.html")


def EngineerForm(request):
    if request.method == "GET":
         form = EngForm()
         return render(request, "Engineers/eform.html", {'form':form})
    else:
         form = EngForm(request.POST)
         if form.is_valid():
            form.save()
         return redirect('/engineer/') #pointing to urls.py paths

我的表格.py

from django import forms
from .models import Engineers

class EngForm(forms.ModelForm):

      class Meta:
          model = Engineers
          fields = '__all__'
          labels = {
             'workarea' : 'Zone',
             'face' : 'Picture',
    
            }

      def __init__(self, *args, **kwargs):
          super(EngForm, self).__init__(*args, **kwargs)
          self.fields['position'].empty_label='Select'
          self.fields['workarea'].empty_label='Select'
          self.fields['face'].required = False

我的模特

from django.db import models

class Engineers(models.Model):
   position = (
       ('NOC', 'NOC'),
       ('Supervisor', 'Supervisor'), 
       ('Site Manager','Site Manager'), 
       ('Site Engineer', 'Site Engineer'),
      )

   region = (
       ('SS','South-South'),('SW','SW'),('SE','SE'), 
       ('NE','NE'),('NW','NW'),('NC','NC'),
       )

   firstname = models.CharField(max_length=20)
   lastname = models.CharField(max_length=20)
   email = models.EmailField(max_length=50)
   username = models.CharField(max_length=20)
   phone = models.IntegerField()
   position = models.CharField(max_length=20, choices=position)
   workarea = models.CharField(max_length=20, choices=region)
   face = models.ImageField(upload_to='', height_field=15, width_field=9)

我的问题是，数据库表返回空行。

已解决。应用@GwynBleidD suggest，我查看了文档，然后重新排列了代码

def EngineerForm(request):
if request.method == "POST":
    form = EngForm(request.POST)
    if form.is_valid():
        form.save()
        return redirect('/engineer/') #pointing to urls.py paths
else:
    form = EngForm()
return render(request, "Engineers/eform.html", {'form':form})

您的视图正在执行重定向，即使表单无法验证。这意味着，如果出现任何验证错误，您将不知道这些错误。我的建议是将视图更改为与中的示例更加内联，并查看表单是否正确验证。此外，如果模型中的

face

字段不是必需的，则需要将其设置为

blank=True

。
