Using django. I have the following model:
class Postagem(models.Model):
id = models.AutoField(primary_key=True, editable=False)
descricao = models.CharField(max_length=50)
area = models.ForeignKey('core.Area', null=True)
user = models.ForeignKey('User')
categoria = models.CharField(max_length=50, null=True)
post = models.FileField(upload_to='posts/', null=True)
thumbnail = models.FileField(upload_to='posts/', null=True)
def __str__(self):
return self.descricao
The Following form:
class PostForm(forms.ModelForm):
categoria = forms.ChoiceField(choices=[("Video","Vídeo"),("Audio","Aúdio"),("Imagem","Imagem"),("Musica","Música")], required=True)
thumbnail = forms.FileField(required=False)
class Meta:
model = Postagem
fields = ['descricao', 'area', 'user', 'post']
View:
def profileView(request):
context = getUserContext(request)
if request.method == 'POST':
exception=None
userDict = {}
userDict["user"] = context["user"].id
if "categoria" in request.POST:
newPost = request.POST.copy()
newPost.update(userDict)
form = PostForm(newPost,request.FILES)
print("postform POST: ",newPost, " File ",request.FILES)
if form.is_valid():
print("valid")
try:
form.save()
print("saved")
return HttpResponseRedirect(reverse_lazy('accounts:profile'))
except IntegrityError as e:
print("Integrity Error")
exception=e
else:
print("PostForm error")
print(form.errors)
form.non_field_errors=form.errors
if exception is not None:
form.non_field_errors.update(exception)
context['form']=form
posts = Postagem.objects.get_queryset().order_by('id')
paginator = Paginator(posts, 12)
page = request.GET.get('page')
context["areas"] = Area.objects.all()
try:
posts = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
posts = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
posts = paginator.page(paginator.num_pages)
context["posts"]=posts
return render(
request,
'accounts/profile.html',
context
)
And at last the template:
{% for post in posts %}
{% if forloop.counter0|divisibleby:4 or forloop.counter0 == 0 %}
<div id="grid-profile" class="row grid">
<div class="col-md-1"></div>
{% endif %}
{% ifnotequal post.categoria "Imagem"%}
<iframe id=post{{forloop.counter}} width="420" height="315"
src={{post.post.url}}>
</iframe>
{% else %}
<div class="col-md-2">
<button type="button" id="modal1trigger" data-toggle="modal" data-target="#modal1"><img class="img-responsive" src={{post.post.url}}></img></button>
</div>
{% endifnotequal %}
{% if forloop.counter|divisibleby:4 or forloop.counter == posts|length %}
<div class="col-md-1"></div>
</div>
{% endif %}
{% endfor %}
<div class="pagination">
<span class="step-links">
{% if posts.has_previous %}
<a href="?page={{ posts.previous_page_number }}">previous</a>
{% endif %}
<span class="current">
Page {{ posts.number }} of {{ posts.paginator.num_pages }}.
</span>
{% if posts.has_next %}
<a href="?page={{ posts.next_page_number }}">next</a>
{% endif %}
</span>
</div>
I cut some of the template... Anyways, I want to be able to add all kinds of posts. Songs, Videos, Images, Docs, etc. And it IS working. The posts are being added. But, I'm having a recurring error and I don't know why. That could be very dangerous so I started looking into it, but with no luck in finding an acceptable answer. The error only happens when trying to get a song or a video.

Edit:
Using Django 1.11.3, Windows 10, Tested with Opera and Chrome, Running server using gulp
**Edit 2: **
Hey, the error ONLY HAPPENS if there is a iframe tag in the html!!
It appears that its a python error:
Django ticket: https://code.djangoproject.com/ticket/26995 Python ticket: https://bugs.python.org/issue14574
Didn't managed to solve just yet, if I can I will edit this answer explaining in detail how to solve it.
Edit
It seems to be a error on chrome. It didn't come to me, 'cause I was using Opera, but opera uses chromium as well. In internet explorer the error didn't show.
