Python Django表单发布不起作用-Django只是再次呈现页面

基本上，我已经建立了一个表单来创建组织。当我点击Save按钮时，它只是再次呈现页面-帖子不起作用

请参见下面的我的代码：

models.py

from django.db import models
from accounts.models import User
from datetime import datetime, date

#// ------------ FUNCTIONS -------------//

# Generate Organisation IDs for each organisation
def org_id_generate():
    last_org = Organization.objects.all().order_by('org_id').last()
    if not last_org:
        return 'ORG_001'
    else:
        last_org_id = last_org.org_id
        number_in_id = int(last_org_id[4:7])
        new_number_in_id = number_in_id + 1
        new_org_id = 'ORG_' + str(new_number_in_id).zfill(3)
        return new_org_id

#// ------------ MODELS -------------//

任何帮助都将不胜感激。如果您需要任何其他信息，请告诉我，我将编辑此帖子。

我没有找到任何用html显示错误的代码。 根据views中的函数，如果表单无效，那么它将使用表单呈现页面。 尝试将{form.errors}}添加到html文件中，看看它是否有错误？

我设法解决了它

views.py

from organizations.models import Organization
from forms import OrganizationAddForm

from django.contrib.auth.decorators import login_required

def settings(request):
    return render(request, 'settings/settings.html')

def organizations_settings(request):
    orgs = Organization.objects.all()

    context = {
        'orgs': orgs,
    }
    return render(request, 'settings/settings_organizations.html', context)

def organization_add(request):
    if request.method == 'POST':
        user_email = request.user.email
        form = OrganizationAddForm(request.POST)
        if form.is_valid():
            form.organization_code = form.cleaned_data['organization_code']
            form.company_name = form.cleaned_data['company_name']
            form.legal_name = form.cleaned_data['legal_name']
            form.business_registration_no = form.cleaned_data['brn']
            form.vat_registration_no = form.cleaned_data['vat']
            form.industry_distribution = form.cleaned_data['industry_distribution']
            form.industry_education = form.cleaned_data['industry_education']
            form.industry_healthcare = form.cleaned_data['industry_healthcare']
            form.industry_manufacturing = form.cleaned_data['industry_manufacturing']
            form.industry_retail = forms.cleaned_data['industry_retail']
            form.industry_services = form.cleaned_data['industry_services']

            form.save()
            return redirect('organizations_settings')

    else:
        form = OrganizationAddForm()

    return render(request, 'settings/add_organization.html', {'form': form})

@login_required
def organization_add(request):
    if request.method == 'POST':
        form = OrganizationAddForm(request.POST)
        if form.is_valid():
            form.organization_code = form.cleaned_data['organization_code']
            form.company_name = form.cleaned_data['company_name']
            form.legal_name = form.cleaned_data['legal_name']
            form.business_registration_no = form.cleaned_data['business_registration_no']
            form.vat_registration_no = form.cleaned_data['vat_registration_no']
            form.industry_distribution = form.cleaned_data['industry_distribution']
            form.industry_education = form.cleaned_data['industry_education']
            form.industry_healthcare = form.cleaned_data['industry_healthcare']
            form.industry_manufacturing = form.cleaned_data['industry_manufacturing']
            form.industry_retail = form.cleaned_data['industry_retail']
            form.industry_services = form.cleaned_data['industry_services']
            form.effective_start_date = form.cleaned_data['effective_start_date']
            form.effective_end_date = form.cleaned_data['effective_end_date']
            
            org = form.save(commit=False)

            org.created_by = request.user
            org.last_updated_by = request.user

            org.save()
            return redirect('organizations_settings')

    else:
        form = OrganizationAddForm()

    return render(request, 'settings/add_organization.html', {'form': form})

问题是它无法捕获“创建人”和“上次更新人”字段的用户电子邮件

这可通过以下方式解决：

org = form.save(commit=False)

org.created_by = request.user
org.last_updated_by = request.user

请注意，以下两个帖子对我有所帮助：

您好，谢谢您的回复！当我这样做的时候，我会得到以下由这个字段创建的结果。此字段上次更新是必需的。@ph4NT0这些只是表单的错误，因为您在模型中定义了

创建人
和
上次更新人
字段。是的，非常感谢你！我设法解决了！
