我尝试创建表单，并将use输入的值传递给数据库。
models.py
from django.db import models
class Evangelized(models.Model):
full_name = models.CharField(max_length = 128)
email = models.EmailField()
mobile_no = models.CharField(unique = True, max_length = 128)
twitter_url = models.CharField(unique = True, max_length = 128)
GENDER_CHOICES = (('M', 'Male'), ('F', 'Female'), ('U', 'Unisex/Parody'))
gender = models.CharField(max_length=1, choices=GENDER_CHOICES)
AREA_CHOICES = (('Govt', 'Govt'), ('Entertainment', 'Entertainment'), ('Automobile', 'Automobile'),
('Careers', 'Careers'), ('Books', 'Books'), ('Family', 'Family'), ('Food', 'Food'),
('Gaming', 'Gaming'), ('Beauty', 'Beauty'), ('Sports', 'Sports'), ('Events', 'Events'),
('Business', 'Business'), ('Travel', 'Travel'), ('Health', 'Health'), ('Technology','Technology'))
area_of_interest = models.CharField(choices = AREA_CHOICES, max_length = 128)
other_area_of_interest = models.CharField(blank = True, max_length = 128)
city = models.CharField(max_length = 128)
BOOL_CHOICES = ((True, 'Yes'), (False, 'No'))
other_social_accounts = models.BooleanField(choices = BOOL_CHOICES, default = None)
questions = models.CharField(blank = True, max_length = 1280)
about_yourself = models.CharField(blank = False, max_length = 1280)
referrer = models.CharField(max_length = 128)
forms.py
from django import forms
from rango.models import Evangelized
class EvangelizedForm(forms.ModelForm):
full_name = forms.CharField(help_text="Full Name")
email = forms.CharField(help_text="Email ID")
mobile_no = forms.CharField(help_text="Mobile number")
twitter_url = forms.CharField(help_text="Twitter URL")
gender = forms.ChoiceField(widget=forms.RadioSelect(),
choices=Evangelized.GENDER_CHOICES, help_text="Gender")
area_of_interest = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(),
choices=Evangelized.AREA_CHOICES, help_text="Areas of interest(Upto 3)")
"""def clean_area_of_interest(self):
if len(self.cleaned_data['area_of_interest']) > 3:
raise forms.ValidationError('Select no more than 3.')
return self.cleaned_data['area_of_interest']"""
other_area_of_interest = forms.CharField(help_text="Other area of interest")
city = forms.CharField(help_text="City")
other_social_accounts = forms.CharField(widget=forms.RadioSelect(),choices=Evangelized.BOOL_CHOICES, help_text="Do you have other social accounts?", max_length=128)
questions = forms.CharField(help_text="Do you have any questions?")
about_yourself = forms.CharField(help_text="Tell us about yourself")
referrer = forms.CharField(help_text="I heard about this platform via:")
class Meta:
model = Evangelized
fields = ('full_name', 'email', 'mobile_no', 'twitter_url', 'gender', 'area_of_interest', 'other_area_of_interest', 'city', 'other_social_accounts',
'questions', 'about_yourself', 'referrer')
views.py
def fillform(request):
if request.method == 'POST':
form = EvangelizedForm(request.POST)
if form.is_valid():
form.save(commit = True)
return index(request)
else:
form.errors
else:
form = EvangelizedForm()
return render(request, 'rango/fillform.html', {'form': form})
但是，我遇到以下错误：
Exception Type: TypeError at /rango/
Exception Value: __init__() got an unexpected keyword argument 'unique'
我的代码似乎有什么问题？这个错误意味着什么？
编辑：
我修改了forms.py文件的源代码，并且在原始标题中也略有机会。似乎我的表单字段中的参数中的choices键生成错误。但是，代码在语法上是正确的，对吧？
答案 0 :(得分：0)
您mobile_no之类的表单字段例如没有unique参数。只有模型字段才有。您必须从表单模型中删除所有unique个参数。

我已经弄清楚是什么导致了这个错误。 choices参数应该在forms.py中的小部件构造函数中定义，如下所示：
from django import forms
from rango.models import Evangelized
class EvangelizedForm(forms.ModelForm):
full_name = forms.CharField(help_text="Full Name")
email = forms.CharField(help_text="Email ID")
mobile_no = forms.CharField(help_text="Mobile number")
twitter_url = forms.CharField(help_text="Twitter URL")
gender = forms.ChoiceField(widget=forms.RadioSelect(
choices=Evangelized.GENDER_CHOICES), help_text="Gender")
area_of_interest = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(
choices=Evangelized.AREA_CHOICES), help_text="Areas of interest(Upto 3)")
"""def clean_area_of_interest(self):
if len(self.cleaned_data['area_of_interest']) > 3:
raise forms.ValidationError('Select no more than 3.')
return self.cleaned_data['area_of_interest']"""
other_area_of_interest = forms.CharField(help_text="Other area of interest")
city = forms.CharField(help_text="City")
other_social_accounts = forms.CharField(widget=forms.RadioSelect(choices=Evangelized.BOOL_CHOICES), help_text="Do you have other social accounts?", max_length=128)
questions = forms.CharField(help_text="Do you have any questions?")
about_yourself = forms.CharField(help_text="Tell us about yourself")
referrer = forms.CharField(help_text="I heard about this platform via:")
class Meta:
model = Evangelized
fields = ('full_name', 'email', 'mobile_no', 'twitter_url', 'gender', 'area_of_interest', 'other_area_of_interest', 'city', 'other_social_accounts',
'questions', 'about_yourself', 'referrer')
