Django HTML for loop not showing corresponding values

Question

I am using a for loop in an HTML Template, it recognizes the fact that they are there but it does not show them in the page like it should.

my views:

    person = []
    x = people.objects.filter(deal='q')
    for person in x:
         print(person.name)
         if person.paid_status == True:
             person.append(lender)
     return render(request, '.html', {'person': person})

my template:

<div>
    {% if person %}
        There are {{ person|length }} persons.
        {% for p in person %}
    <p> {{ p.name }} </p>
        {% endfor %}
    {% else %}
         <p> As of now no persons have appeared. </p>
    {% endif %}
</div>

in the console it prints the persons name correctly so I am confused why it does not work in the HTML

All I see is that there are 2 persons(which is correct) but then it does not list them.

Thanks in advance.

You are overwriting the variable person inside your loop.

Change the list person to persons and it should work fine.

Your view:

persons = []
x = people.objects.filter(deal='q')
for person in x:
     if person.paid_status == True:
         persons.append(person)
 return render(request, '.html', {'persons': persons})

Your template:

<div>
    {% if persons %}
        There are {{ persons|length }} persons.
        {% for p in persons %}
        <p> {{ p.name }} </p>
        {% endfor %}
    {% else %}
         <p> As of now no persons have appeared. </p>
    {% endif %}
</div>

This worked, by overwhelming the variable what did you mean?

On the first line you do person = [], then in the loop you do for person in x:. When you do that, the variable person being used to iterate the list x is overwriting the list person you just created 2 lines above. If my answer is the correct answer, please, mark as the correct one, it would help me a lot.
