, так что я новичок здесь в django и уже получил некоторую оценку generic views, но мне действительно трудно понять UpdateView, CreateView и DeleteView всю информацию, которую я поиск до сих пор не дает мне понять, как их использовать. Итак, у меня есть форма регистрации, в которой есть имя пользователя и пароль, но они сохраняются в различных table или model; Вы можете взглянуть на forms.py, и попытка UpdateView дает мне только ошибку в моем проекте. Поэтому, как я обнаружил на некоторых форумах, я не могу использовать UpdateView для foreign key таблицы, поскольку она выглядит только как primary key Так что вместо того, чтобы использовать их, я использую FormView вместо 3 generic view. Можно ли использовать FormView в качестве опции, кроме 3 generic view?
Вот мой исходный код.
forms.py:
from django import forms
class UserCredentialForm(forms.Form):
username = forms.CharField(label = 'Email', widget = forms.TextInput(
attrs = {
'id': 'id_login_username',
'class': 'form-control',
'autocomplete': 'off',
}
), required = False)
password = forms.CharField(label = 'Password', widget = forms.PasswordInput(
attrs = {
'id': 'id_login_password',
'class': 'form-control',
}
), required = False)
class UserInfoForm(forms.Form):
year = {}
days = {}
month = {
'': '---------',
'Jan': 'January', 'Feb': 'February', 'Mar': 'March',
'Apr': 'April', 'May': 'May', 'Jun': 'June', 'Jul': 'July',
'Aug': 'August', 'Sep': 'September', 'Oct': 'October',
'Nov': 'November', 'Dec': 'December'
}
gender = {
'Male': 'Male', 'Female': 'Female',
'Not Specify': 'Not Specify'
}
year[''] = '---------'
days[''] = '---------'
from datetime import datetime
for i in range((int(datetime.now().strftime('%Y'))), (1920 - 1), -1):
year[i] = i
for i in range(1, (31 + 1)):
days[i] = i
password = forms.CharField(label = 'Password', widget = forms.PasswordInput(
attrs = {
'id': 'id_signup_password',
'class': 'form-control',
'placeholder': 'Password'
}
), required = True)
email = forms.EmailField(label = 'Email', widget = forms.EmailInput(
attrs = {
'id': 'id_signup_email',
'class': 'form-control',
'placeholder': 'Email',
'autocomplete': 'off'
}
), required = True)
firstname = forms.CharField(label = 'Firstname', widget = forms.TextInput(
attrs = {
'id': 'id_signup_firstname',
'class': 'form-control',
'placeholder': 'Firstname',
'autocomplete': 'off'
}
), required = True)
lastname = forms.CharField(label = 'Lastname', widget = forms.TextInput(
attrs = {
'id': 'id_signup_lastname',
'class': 'form-control',
'placeholder': 'Lastname',
'autocomplete': 'off'
}
), required = True)
gender = forms.ChoiceField(label = 'Gender', widget = forms.Select(
attrs = {
'id': 'id_signup_gender',
'class': 'form-control',
}
), choices = list(gender.items()), required = False)
birthdate_year = forms.ChoiceField(label = 'Year', widget = forms.Select(
attrs = {
'id': 'id_signup_birthyear',
'class': 'form-control',
}
), choices = list(year.items()), required = True)
birthdate_day = forms.ChoiceField(label = 'Day', widget = forms.Select(
attrs = {
'id': 'id_signup_day',
'class': 'form-control',
}
), choices = list(days.items()), required = True)
birthdate_month = forms.ChoiceField(label = 'Month', widget = forms.Select(
attrs = {
'id': 'id_signup_month',
'class': 'form-control',
}
), choices = list(month.items()), required = True)
