Re: Pagination - Not Working

[Aakash Baranwal]

I have also used Ajax with that. It's load more button is not working, it
is showing the 10 posts which is the limit I set in the beginning, but not
going beyond that.

Re: Pagination - Not Working

[Aakash Baranwal]

Hello,

Thanks for offering me your help, but the problem is I can't upload it on
internet as I have signed a Non Disclosure Agreement for the project in
which I am working, so totally helpless in this case.

However I might be able to give a specific portion of what you might need
for resolving this issue.

I am extremely sorry about this.

Re: Pagination - Not Working

[Aakash Baranwal]

It did not work. I tried making it using JavaScript like in websites if you
might have seen when you press the button then only it shows the content or
scrolls down.

Re: Pagination - Not Working

[Aakash Baranwal]

Thanks a lot. I worked that out by making the Load More as a clickable
button which when pressed will show the contents.

Re: Deployment on Heroku

[Aakash Baranwal]

It goes into the site-packages in linux as well but it was not showing
there, infact even after I installed it there itself, then also it was not
there, however when I checked in the terminal by reinstalling it said that
requirement is already satisfied and its already in the requirements.txt
file.

I used this command :
as per the guide in this gunicorn guide by digital ocean
<https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04>
which is gunicorn --bind 0.0.0.0:8000 myproject.wsgi

Now when i run it in the browser, it says internal server error and the
terminal shows this error:

  File
"/home/aakash/Dev/tweetme/lib/python3.6/site-packages/gunicorn/workers/sync.py",
line 135, in handle
self.handle_request(listener, req, client, addr)
  File
"/home/aakash/Dev/tweetme/lib/python3.6/site-packages/gunicorn/workers/sync.py",
line 176, in handle_request
respiter = self.wsgi(environ, resp.start_response)
TypeError: __call__() takes 2 positional arguments but 3 were given


Kindly tell me what I might be doing wrong and also check my procfile if I
am going the right way

Caltech Pedestrian Detection Annotations

[Aakash Baranwal]

Hi Everybody,

This is not exactly a Django related question, but I need help.

I am working on a project, and I have to use Caltech Pedestrian Detection
 data
set. However, I am not able to get the output as desired as the files are
in VBB format and moreover I am not able to interpret the matrix.

If anyone happens to have any kind of documentation which will help in
using the data set for training the model and correctly interpreting the
data, or are aware how to correctly use it, please help me.

I shall be extremely thankful.

Thanks in advance.

With Kind Regards

Aakash

Integrating Machine Learning Model in Django

[Aakash Baranwal]

Hi Everybody,

I need a help in integrating a machine learning model with my website.

I have a file upload button where I can upload either an image or a video.
After it is uploaded, I want to run my model into it and whatever is the
result I want to display it and keep a record of the whole process.

Also, I wish to add a feature of connecting my website with my CCTV camera,
so I can have a live video feed instead of uploading a video and then do
the same.

PS - I can select whether I want to upload the image or the video or I want
to use the live footage of the camera and run my model on that.

Thank You in advance.

With Kind Regards

Aakash

Re: Integrating Machine Learning Model in Django

[Aakash Baranwal]

Thanks a  lot.

I read about it and I think it will do the job for me. I plan to send a
live video and chunk it after 1 hour time and then run the model on it.

How to create a REST API for calling my model to run on the video and then
another challenge is how to show the result video to the person who
requested for the service i.e. the one who uploaded the video.

Thank you for the help.

Getting a TypeError

[Aakash Baranwal]

Hi Everybody,

Kindly help me out.

My views.py file is:

def video_detail_view(request):
obj = str(Video.objects.get(id=id))
print(obj)
context = {
"object": obj
}
return render(request, "deploy/list_view.html", context)


def video_list_view(request):
queryset = Video.objects.all()
print(queryset)
for obj in queryset:
print(obj.Video_Description, obj.videofile)
context = {
"object_list": queryset
}
return render(request, "deploy/detail_view.html", context)


The models.py file is:

class Video(models.Model):
Video_Description= models.CharField(max_length=500)
videofile= models.FileField(upload_to='videos/', null=True,
verbose_name="")

def __str__(self):
return self.Video_Description + ": " + str(self.videofile)

The error I am getting is:
int() argument must be a string, a bytes-like object or a number not
'builtin_function_or_method'.

The error is in views.py file in obj = str(Video.objects.get(id=id)).

Kindly help me out.

Thank you

Actually, his solution was correct because when I provided the encryption

Search and display results using calendar in Django

[Aakash Baranwal]

Hi Everybody,

I need help.

I want to perform search operation using calendars. I shall select two
dates i.e. max_date which shall not be more than the current date but can
be less and min_date, these two shall be the days range. The result fields
are: in_count, out_count, and dwell_time. The output should sum up all the
results of all the days which are between the max_date and min_date. How
can I do that? Please help. Is there a need to define a model for this? I
am completely clueless.

Expected result is getting the output in the same form as in
result_list.html with the result of all the fields of the days starting
from min_date till max_date getting displayed and the min_date and max_date
should also be shown in the template. Kindly help.

My model :

class Result(models.Model):

in_count   = models.PositiveIntegerField()
out_count  = models.PositiveIntegerField()
date_time  = models.DateTimeField()
time   = models.TimeField()

def __str__(self):

return "{},{},{},{}".format(self.in_count, self.out_count,
self.date_time, self.time)

My views.py

class ResultListView(ListView):

def get_queryset(self, *args, **kwargs):
qs = Result.objects.all()
print(self.request.GET)
query = self.request.GET.get("q", None)
if query is not None:
qs = qs.filter(
Q(in_count__icontains=query) |
Q(out_count__icontains=query) | Q(date_time__icontains=query) |
Q(time__icontains=query))
return qs

def get_context_data(self, *args, **kwargs):
context = super(ResultListView, self).get_context_data(*args, **kwargs)

return context

class ResultDetailView(DetailView):
queryset = Result.objects.all()


My result_list.html

Result on {{ object.date_time}}
  
Result of Model
 In Count {{ object.in_count }}

Out Count {{ object.out_count}}

Re: Search and display results using calendar in Django

jQuery(function () {

jQuery('#datetimepicker7').datetimepicker({
useCurrent: false //Important! See issue #1075
});
jQuery("#datetimepicker6").on("dp.change", function (e) {

});
jQuery("#datetimepicker7").on("dp.change", function (e) {
jQuery('#datetimepicker6').data("DateTimePicker").maxDate(e.date);
});
});



Now, I want to select multiple dates using this, say start_date and
end_date which will filter the dates between that range and then sum the
value of in_count and out_count and display it to the user.

So, far what I think I should use is, but I am not sure how to do it and
display the result to the user. Someone please help me here.

Result.objects.filter(

date_time__range=[start_date,
end_date]).aggregate(Sum('in_count'), Sum('out_count'))
