Django 表单发布不起作用 - Django 只是再次渲染页面

Question

基本上我已经建立了一个表格来创建组织。当我点击“保存”按钮时，它只是再次呈现页面 - POST 不起作用。请参阅下面我的代码：models.pyfrom django.db import modelsfrom accounts.models import Userfrom datetime import datetime, date#// ------------ FUNCTIONS -------------//# Generate Organisation IDs for each organisationdef 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 -------------//class Organization(models.Model):    org_id = models.CharField(primary_key=True, max_length=7, default=org_id_generate, editable=False)    organization_code = models.CharField(max_length=20)    company_name = models.CharField(verbose_name="Company Name", max_length=60)    legal_name = models.CharField(verbose_name="Legal Name", max_length=100)    industry_distribution = models.BooleanField(verbose_name="Distribution", default=False)    industry_education = models.BooleanField(verbose_name="Education", default=False)    industry_healthcare = models.BooleanField(verbose_name="Healthcare", default=False)    industry_manufacturing = models.BooleanField(verbose_name="Manufacturing", default=False)    industry_retail = models.BooleanField(verbose_name="Retail", default=False)    industry_services = models.BooleanField(verbose_name="Services", default=False)    business_registration_no = models.CharField(verbose_name="Business Registration Number", max_length=15, blank=True)    vat_registration_no = models.CharField(verbose_name="VAT Registration Number", max_length=15, blank=True)

Answer 1

我没有找到任何代码来显示 html 中的错误。根据views中的函数，如果表单无效，则使用表单渲染页面。尝试在html文件中添加{{form.errors}}看看是否有错误？

Answer 2

我设法解决了它。

views.py

@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“创建者”和“上次更新者”字段的用户电子邮件。

这是通过使用以下方法解决的：

org = form.save(commit=False)

org.created_by = request.user

org.last_updated_by = request.user
