Django - Items not showing up in Products page

I'm trying to create a basic e-commerce site in Django. I have created a products page and when I open the page, my products are not showing up. I'm new to Django and have no idea what to do.

I also debugged the NameError for my Product model. Now the products are not showing up.
I had encountered this problem in another project as well. Not knowing what to do, I created that project from scratch once more. The problem still continues.
I think your are confusing !
do the following instruction :
1-remove this code
def products(request):
return render(request, 'products.html')
2- in products.html remove
{% extends 'base.html' %}
add this code :
{% extends 'index.html' %}
I think your mistake in for loop check the
products = Product.objects.all()
return render(request, 'index.html', {'products': products}) #products is send to index.html and the the for loop syntax is for name_of_params in para
Your for loop is wrong.
Yours: {%for p in products%}
Solution: {%for product in p %}

Django: Message appearing twice

I've came across an issue where message is displayed twice even though its called only once. Sometimes only one message is displayed however, most of the time 2 messages are.
My view:
def register(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
if form.is_valid():
form.save()
messages.success(request, f'Account created has been creted! You can log-in now.')
return redirect('login')
else:
if request.user.is_authenticated:
messages.error(request, 'You are loged-in and in order to registrate you must be loged-out.')
return redirect('blog-home')
else:
form = UserRegisterForm()
return render(request, 'users/register.html', {'form': form,'title':'Register Page'})
And here is my template:

You can see that in the {% if messages %} block, message is called only once.

{% endfor %}

I don't know the problem that is causing this it was working fine when suddenly i did some changes with query to create a multi step form and when checked the database I was getting some null entries and when i clicked or tried to delete them I got error.I've included the image of null entries i was getting.
Basically your Model's __str__ method is returning None. Means both of the field's value is None. You need to return a string value from that method. For example:
class Personal_Detail(models.Model):
# rest of the code
def __str__(self):
return self.beneficiary_adhaar_name or self.beneficiary_id_name or str(self.pk)

How to fix: Django forms: {{ form }} doesn't show up any result in html page

I've created a django form:
#forms.py
from django import forms
class NameForm(forms.Form):
subject = forms.CharField(max_length=100)
message = forms.CharField(widget=forms.Textarea)
sender = forms.EmailField()
cc_myself = forms.BooleanField(required=False)
and in view file:
#views.py
def get_form(request):
print(request.POST)
form = NameForm(request.POST or None)
if form.is_valid():
print(form.cleaned_data)
return render(request, "name.html", {"title": "Contact us"})
I've imported to a html file inside templates folder:
#templates/name.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="/your-name/" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="Submit">
</form>
</body>
</html>
However, it doesn't show up any thing just a submit button. I have no idea what is the issue. I'll be so grateful for a solution around this issue.
Update: If I create a new html file, the form is shown there. However, if I use it in my main html including boostarp, it is not showing up. Here is the full code of my html:
{% extends 'base.html' %}
{% block content %}

I attached images of my home page and linked page,
please help me regarding the issue
n the above code, the second page is throwing me a error
django.urls.exceptions.NoReverseMatch: Reverse for 'favorite' not found. 'favorite' is not a valid view function or pattern name**
Please someone help me out where im wrong! Thanks in advance!
I can't see any url with the name favorite here, which is what the error is telling you as well:
app_name = 'music'
urlpatterns = [
url(r'^$',views.IndexView.as_view(), name='index'),
url(r'^(?P<pk>[0-9]+)/$',views.DetailView.as_view(), name='details'),
]
you probably copy pasted the details.html or you simly forgot to specify the "favorite" url in the app "music"
EDIT:
As you have clarified that you are unable to solve the problem on your onw:
Change details.html as such:
<form action="{% url 'music:favorite' album.id %}" method="post">
replace it with
<form action="#" method="post">
you're site should then at least load.
EDIT2:
After watchich the youtube video you linked in your comment:
all the answers are in the video and its comments!
You didn't update details.html. Watch closely around min 1:50.
Btw my solution of replacing the form action will work as well, but the output will be slightly different from what you might expect...
I hope this will get you started ;)
