[英]NOT NULL constraint failed error
I keep getting this error: "NOT NULL constraint failed: users_userprofile.user_id" when I try to submit a form当我尝试提交表单时,我不断收到此错误:“NOT NULL 约束失败:users_userprofile.user_id”
from django.db import models
from django.contrib.auth.models import User
class UserProfile(models.Model):
#Esta linea es requerira. Linkea UserProfile a un User model
user = models.OneToOneField(User)
#atributos adicionales
about_me = models.TextField(max_length=100,default='',blank=True)
experience = models.TextField(max_length=250,default='',blank=True)
offers = models.TextField(max_length=110,default='',blank=True)
This is the forms.py: from django import forms from users.models import UserProfile from django.contrib.auth.models import User这是forms.py: from django import forms from users.models import UserProfile from django.contrib.auth.models import User
class UserForm(forms.ModelForm):
password = forms.CharField(min_length=6,label='', widget=forms.PasswordInput(attrs={'placeholder': 'Password','required':'true','class':"form-control"}))
username = forms.CharField(label='', min_length=6,
widget=forms.TextInput(attrs={'placeholder': 'Username','required':'true','class':"form-control",'autofocus':'true'}))
email = forms.CharField(label='',
widget=forms.TextInput(attrs={'placeholder': 'Email','required':'true','class':"form-control"}))
class Meta:
model = User
fields = ('username', 'email', 'password')
class UserProfileForm(forms.ModelForm):
about_me = forms.CharField(label='',
widget=forms.Textarea(attrs={'placeholder': 'Sobre mi','required':'true','class':"form-control"}))
first_name = forms.CharField(label='',
widget=forms.TextInput(attrs={'placeholder': 'Nombre','required':'true','class':"form-control"}))
last_name = forms.CharField(label='',
widget=forms.TextInput(attrs={'placeholder': 'Apellidos','required':'true','class':"form-control"}))
experience = forms.CharField(label='',
widget=forms.TextInput(attrs={'placeholder': 'Experiencia','required':'true','class':"form-control"}))
offers = forms.CharField(label='',
widget=forms.Textarea(attrs={'placeholder': 'Mensaje','required':'true','class':"form-control"}))
class Meta:
model = UserProfile
fields =('first_name','last_name','about_me','experience','offers')
This is the template:这是模板:
{%extends 'base.html'%}
{%block content%}
{% if user.is_authenticated %}
<h1>Edita tu perfil</h1>
<form id='profile' method='post' action='/edit_profile/'>
{% csrf_token %}
{{profile.as_p}}
<button type='submit'>Editar</button>
</form>
{%endif%}
{%endblock%}
Thanks before hand提前致谢
EDIT:编辑:
The error was in the views.py I needed to add an instance to the form, like this:错误在我需要向表单添加一个实例的 views.py 中,如下所示:
form = UserProfileForm(data=request.POST, instance=profile)
This is my complete views.py:这是我完整的views.py:
def edit_profile(request):
try:
profile = request.user.userprofile
except UserProfile.DoesNotExist:
profile = UserProfile(user=request.user)
if request.method == 'POST':
form = UserProfileForm(data=request.POST, instance=profile)
if form.is_valid():
form.save()
return HttpResponse("Exito!")
else:
form = UserProfileForm(instance=profile)
else:
form = UserProfileForm()
return render(request,
'editprof.html',
{ 'form': form})
Problem is that user in UserProfile is required, but you are not setting user field in UserProfileForm.问题是 UserProfile 中的用户是必需的,但您没有在 UserProfileForm 中设置用户字段。 Database didn't get user_id, so it tried to set null on this field, but field have not not null constraint.数据库没有得到user_id,所以它试图在这个字段上设置为空,但该字段没有非空约束。 You can set null=True on field definition in UserProfile model, or overwrite save (or probably is_valid) form method to set user automatically, or add user field to UserProfileForm, or whatever what you want.您可以在 UserProfile 模型中的字段定义上设置 null=True,或覆盖保存(或可能是 is_valid)表单方法以自动设置用户,或将用户字段添加到 UserProfileForm,或任何您想要的。
In your model give a null在你的模型中给出一个空值
user = models.OneToOneField(User, null=True)
about_me = models.TextField(max_length=100,default='',blank=True, null=True)
experience = models.TextField(max_length=250,default='',blank=True, null=True)
offers = models.TextField(max_length=110,default='',blank=True, null=True)
