When i try to create an new post with http://localhost:8000/create/, i get this error. I couldn't find the solution thought they seem similar. I follows some blog tutorial
I can't paste the settings.py here because there to much code in the post but i think the settings.py is fine btw
My models.py (* i deleted some code maynot involve)
User = get_user_model()
class Author(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
profile_picture = models.ImageField()
def __str__(self):
return self.user.username
class Post(models.Model):
title = models.CharField(max_length=100)
overview = models.TextField()
detail = models.TextField()
timestamp = models.DateTimeField(auto_now_add=True)
content = RichTextUploadingField(config_name='post_ckeditor')
comment_count = models.IntegerField(default=0)
view_count = models.IntegerField(default=0)
author = models.ForeignKey(Author, on_delete=models.CASCADE)
thumbnail = models.ImageField()
categories = models.ManyToManyField(Category)
featured = models.BooleanField()
previous_post = models.ForeignKey('self', related_name='previous', on_delete=models.SET_NULL, blank = True, null = True)
next_post = models.ForeignKey('self', related_name='next', on_delete=models.SET_NULL, blank = True, null = True)
My views.py
def get_author(user):
qs = Author.objects.filter(user=user)
if qs.exists():
return qs[0]
return None
pass
def post_create(request):
form = PostForm(request.POST or None, request.FILES or None)
author= get_author(request.user)
if request.method == 'POST':
if form.is_valid():
form.instance.author = author
form.save()
return redirect(reverse('post-detail', kwargs={
'id': form.instance.id
}))
context = {
'form': form
}
return render(request, 'post_create.html', context)
pass
My forms.py
from django import forms
from .models import Post, Comment
class PostForm(forms.ModelForm):
content = forms.CharField
class Meta:
model = Post
fields = ('title', 'overview', 'content', 'thumbnail', 'categories', 'featured', 'previous_post', 'next_post')
class CommentForm(forms.ModelForm):
content = forms.CharField(widget=forms.Textarea(attrs={
'class':'form-control',
'placeholder':'Type your comment',
'id':'usercomment',
'rows':4
}))
class Meta:
model = Comment
fields = ('content', )
Please help !
Whenever there is a change in model fields or new model added or removed, you should migrate. And pass a default object to foreign key if not null.
If you are trying to save request.user
in the author field you don't need to write the extra methods just do like this.
if request.method == 'POST':
if form.is_valid():
post =form.save(commit=False)
post.author = request.user
post.save()
return redirect(reverse('post-detail', kwargs={'id': post.id }))
