Question

I was creating a post based website i want to show the author's name to show up in the post it works in the admin site when adding posts but when i try uploading a post from the site the form is not getting validated therefore it is not getting saved please help
model :
from django.conf import settings
class MemeImg(models.Model):
Title = models.CharField(max_length=500)
op = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, default=None, blank=True, null=True)
date_created = models.DateTimeField(auto_now_add=True)
Post_Img = CloudinaryField('Post')
forms :
class PostImg(forms.ModelForm):
class Meta:
model = MemeImg
fields = ['Title', 'op', 'Post_Img']
view :
#login_required(login_url='/login')
def post(request):
func = data(request)
if request.method == 'POST':
form = PostImg(request.POST, request.FILES, instance=request.user)
form.op = request.user
if form.is_valid():
print('success')
posts = form.save(commit=False)
posts.op = request.user
form.save()
return HttpResponseRedirect('https://youtu.be/dQw4w9WgXcQ')
else:
print("fail")
form = PostImg(request)
ctx = {
'form': form,
'url': func[0],
'name': func[1],
'date': func[2],
}
return render(request, 'Post.html', ctx)
and finally the post page template :
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
<div class="container">
{{ form.Title|materializecss }}
<div class="file-field input-field">
<div class="btn">
<span>File</span>
<input type="file">
</div>
<div class="file-path-wrapper">
{{ form.Post_Img }}
<input class="file-path validate" type="text">
</div>
</div>
<button class="btn waves-effect waves-light" type="submit" name="action">Submit
<i class="material-icons right">send</i>
</button>
</div>
</form>
If anymore code is required please comment it
Thanks a lot

I think your problem come from the form instance which is instance=request.user, actually the instance is supposed to be the MemeImg object instance and not the user, that's making it not to save the image. So i have deleted the instance and also i don't know what you are using those extra context variable for 'url': func[0],'name': func[1], 'date': func[2] ?, so i deleted them too keep things simple. Now i think you should be able to save without any Issues.
#login_required(login_url='/login')
def post(request):
if request.method == 'POST':
form = PostImg(request.POST, request.FILES)
if form.is_valid():
print('success')
data = form.save(commit=False)
data.op = request.user
form.save()
return HttpResponseRedirect('https://youtu.be/dQw4w9WgXcQ')
else:
print("fail")
form = PostImg(request.POST)
ctx = {
'form': form,
}
return render(request, 'Post.html', ctx)
Also your form had in it {{ form.Post_Img }} which i don't no what you are looking to accomplish with that variables?, the right way is doing {{ form.as_p }} or simply just calling the form like this {{ form }} so i have made the correction in you HTML
too.
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
<div class="container">
{{ form.Title|materializecss }}
<div class="file-field input-field">
<div class="btn">
<span>File</span>
<input type="file">
</div>
<div class="file-path-wrapper">
{{ form }}
<input class="file-path validate" type="text">
</div>
</div>
<button class="btn waves-effect waves-light" type="submit" name="action">Submit
<i class="material-icons right">send</i>
</button>
</div>
</form>
