我目前在尝试渲染模型表单时遇到上述错误。
我的表单现在看起来是这样的:
Form.py:
class SettingUpdateForm(ModelForm):
class Meta:
model = SettingsClass
fields = '__all__'
Models.py:
Complex = models.CharField(choices=complex_list , max_length = 22 ,default='1' , unique=True)
#Trial Balance Year To Date
Trial_balance_Year_to_date= models.BooleanField(default = False)
tbytd_Include_opening_balances=models.BooleanField(default = False)
tbytd_Only_use_main_accounts=models.BooleanField(default = False)
tbytd_Print_null_values=models.BooleanField(default = False)
tbytd_Print_description=models.BooleanField(default = True)
tbytd_Print_account=models.BooleanField(default = True)
tbytd_Sort_by_account_name=models.BooleanField(default = True)
#Trial Balance Monthly
Trial_balance_Monthly=models.BooleanField(default = False)
tbm_Only_use_main_accounts=models.BooleanField(default = False)
tbm_Print_null_values=models.BooleanField(default = False)
tbm_Print_description=models.BooleanField(default = True)
tbm_Print_account=models.BooleanField(default = True)
tbm_Sort_by_account_name=models.BooleanField(default = True)
当表单试图呈现时，它根据my views.py给出以下错误:

我已经尝试替换表单…有了背景……在我的HTML文档中显示以下内容:

我似乎找不到这可能是什么问题，我已经尝试删除"动作"作为表单标签的一部分，它会呈现表单但是当&;update&;按钮被按下，页面不会重定向到
下面是导致问题的代码
<form method="POST" action="{% url 'viewSettings' settings.pk %}">
在你的viewsettings.html模板中将settings.pk替换为setting.pk
所以应该写上<form method="POST" action="{% url 'viewSettings' setting.pk %}">
在您的views.py中，您将设置传递为上下文中的对象，但在模板中，您正在使用设置，因此错误
要检查导致表单未提交的原因，请执行以下命令
def viewSettings(request, settings_pk):
setting = get_object_or_404(SettingsClass, pk=settings_pk)
if request.method == 'GET':
form = SettingUpdateForm(instance=setting)
return render(request, 'main/viewSettings.html', {'setting': setting, 'form':form})
else:
form = SettingUpdateForm(request.POST, instance=setting)
if form.is_valid():
form.save()
return redirect('settingsHome')
else: #add this to your code
print(form.errors)
return render(request, 'main/viewSettings.html', {'setting': setting, 'form':form})
