使用Django模板进行表单验证 [英] Form Validation using Django Templates
本文介绍了使用Django模板进行表单验证的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
$ b
（更新：我添加了我的get pk ，并将其放入我的 pt 变量中，用 patient 字段后，问题是它不会为我的循环创建新的条目，我想节省齿数和状态）
class DentalRecordCreateView（CreateView）：
template_name ='patient / dental_create.html'
model = DentalRecord
fields ='__all__'
success_url ='/ '
def form_valid（self，form）：
tooth = [18,17,16,15,14,13,12,11,21,22,23,24,25， 26,27,28,48,47,46,45,44,43,42,41,31,32,33,34,35,36,37,38]
tooth.reverse（）
mytooth = {}
pt = self.kwargs ['pk']
for t in tooth：
mytooth [{0}。format（t）] = self.request.POST.getl ist（'tooth_'+ str（t），False）＃从form齿返回每个文本框的值。
mytooth2 =.join（mytooth [str（t）]）
form.instance.status = mytooth2
form.instance.position = str（t）
form.instance.patient = PatientInfo.objects.get（pk = pt）
return super（DentalRecordCreateView，self）.form_valid（form）
这是我的模型（已添加）
class DentalRecord（models.Model）：
$ b $ patient = models.ForeignKey（PatientInfo，on_delete = models.CASCADE，null = True，blank = True）
position = models。 CharField（'Teeth'，max_length = 200，null = True，blank = True）＃22,31
status = models.CharField（'Status'，max_length = 200，null = True，blank = True）＃decayed
topArea = models.BooleanField（'TopArea'，default = False）＃布尔
rightArea = models.BooleanField（'RightArea'，default = False）＃布尔
bottomArea = models.BooleanField（ 'BottomArea'，默认= False）＃b oolean
leftArea = models.BooleanField（'LeftArea'，default = False）＃布尔
centerArea = models.BooleanField（'CenterArea'，default = False）＃布尔
我的template.html（已添加）

错误表示（更新）

我发现I找到基于类的视图混淆，没有人有一个很好的教程，如何使用它的CRUD操作？
谢谢
解决方案
覆盖 form_valid 方法，您将直接获取表单对象。将你的逻辑从post方法移到form_valid。您已经提到了success_url属性，请移除post方法。无需显式重定向
$ b $ pre $ class DentalRecordCreateView（CreateView）：
template_name ='patient / dental_create.html'
model = DentalRecord
fields ='__all__'
success_url ='/'
def form_valid（self，form）：
tooth = [18，17 ，16，15，14，13，12，11，21，22，23，24，25，26，27，28，48，47，46，45，44，43，42， b $ b 33,34,35,36,37,38]
tooth.reverse（）
mytooth = {}
for t in tooth：
mytooth [{0}。format（t）] = request.POST.getlist（'tooth_'+ str（t），[]）
＃从form齿返回每个文本框的值。
mytooth2 =.join（mytooth [str（t）]）
form.instance.status = mytooth2
form.instance.position = t
return super（DentalRecordCreateView，self）.form_valid（form）
基于类的视图教程
I created a form inside my template, my problem is to get data without using forms module.
(Update: I added my get pk from previous form and put it in my pt variable to insert in my table with patient field afterwards, the problem is it does not create new entry for my loop. I want to save tooth number and status)
class DentalRecordCreateView(CreateView):
template_name = 'patient/dental_create.html'
model = DentalRecord
fields = '__all__'
success_url = '/'
def form_valid(self, form):
tooth = [18, 17, 16, 15, 14, 13, 12, 11, 21, 22, 23, 24, 25, 26, 27, 28, 48, 47, 46, 45, 44, 43, 42, 41, 31, 32, 33, 34, 35, 36, 37, 38]
tooth.reverse()
mytooth = {}
pt = self.kwargs['pk']
for t in tooth:
mytooth["{0}".format(t)] = self.request.POST.getlist('tooth_' + str(t),False) # returns value each textbox from form tooth. Value for tooth status [decayed, etc.]
mytooth2 = " ".join(mytooth[str(t)])
form.instance.status = mytooth2
form.instance.position = str(t)
form.instance.patient = PatientInfo.objects.get(pk=pt)
return super(DentalRecordCreateView, self).form_valid(form)
Here is my model (Added)
class DentalRecord(models.Model):
patient = models.ForeignKey(PatientInfo, on_delete=models.CASCADE, null=True, blank=True)
position = models.CharField('Teeth',max_length=200, null=True, blank=True) # 22, 31
status = models.CharField('Status',max_length=200, null=True, blank=True) # decayed
topArea = models.BooleanField('TopArea', default=False) # boolean
rightArea = models.BooleanField('RightArea', default=False) # boolean
bottomArea = models.BooleanField('BottomArea', default=False) # boolean
leftArea = models.BooleanField('LeftArea', default=False) # boolean
centerArea = models.BooleanField('CenterArea', default=False) # boolean
My template.html (Added)

The error says that (Updated)
'Could not send URL to django. Error 500. TypeError at /patient/dental/399 can only join an iterable'
I find the I find the class based views confusing, does anyone have a good tutorial on how to use it for CRUD operations?
Thanks
解决方案
Override form_valid method you will directly get form object. Move your logic from post method to form_valid. remove post method as you already mention success_url attribute. no need to redirect it explicitly
class DentalRecordCreateView(CreateView):
template_name = 'patient/dental_create.html'
model = DentalRecord
fields = '__all__'
success_url = '/'
def form_valid(self, form):
tooth = [18, 17, 16, 15, 14, 13, 12, 11, 21, 22, 23, 24, 25, 26, 27, 28, 48, 47, 46, 45, 44, 43, 42, 41, 31, 32,
33, 34, 35, 36, 37, 38]
tooth.reverse()
mytooth = {}
for t in tooth:
mytooth["{0}".format(t)] = request.POST.getlist('tooth_' + str(t), [])
# returns value each textbox from form tooth. Value for tooth status [decayed, etc.]
mytooth2 = " ".join(mytooth[str(t)])
form.instance.status = mytooth2
form.instance.position = t
return super(DentalRecordCreateView, self).form_valid(form)
