JInja2 Template Syntax Error Encountered Unknown tag 'endif'

I am building a basic api based website as I was going to display some info om page and was checking for a condition i encountered --
jinja2.exceptions.TemplateSyntaxError: Encountered unknown tag 'endif'. Jinja was looking for the following tags: 'endblock'. The innermost block that needs to be closed is 'block'.
Below is the palatte I copied form Bootstrap and was modifying and then the error happened -- And Yeah This is my first time posting question here as you can tell!
{% include "header.html" %}
{% block contnet %}
<div class="container-fluid">
<div class="row row-dark">

{% if error %} # <========

You close the "if" twice ({% endif %}) but only open one...
Try this:
Click to Know Upcoming Events Events Batting Bowling Wickets Over
{% if error: %}
{{ error }}
{% endif %}
Mark Otto #mdo 2 Jacob Thornton #fat 3 Larry the Bird #twitter
{% endblock %}
You can move the {% endif %} where you want

Django template for loop is empty in another block

I have a function in my view.py:
#login_required(login_url='login')
def gpd(request,pk):
# get gpd by id
current_gpd = get_gpd(pk)
# get current campaign year #TODO check types
current_campaign = get_campaign(current_gpd.gpd_year)
# get all corporate goals for current campaign
corp_goals = CorporateGoal.objects.filter(gpd_year=current_campaign.year)
compl_weight = []
for goal in corp_goals:
compl_weight.append(goal.corp_factor_weight*current_gpd.bonus.corporate_component//100)
corporate_goals = zip(corp_goals, compl_weight)
if is_manager(request)!=None:
team = get_team(request)
context = {'gpd':current_gpd,
'corporate_goals':corporate_goals,
}
return render(request, 'app/gpd_forms/form_gpd.html', context)
else:
context = {'gpd':current_gpd,
'corporate_goals':corporate_goals,
}
return render(request, 'app/gpd_forms/form_gpd.html', context)
As you can see, in context I have corporate_goal.
My form_gpd.html:
{% extends 'app/navbar/main.html' %}

And it works perfectly. But when in last block summary I want to use corporate_goals one more time - I have nothing on my page, looks like corporate_goals is not exist.
my summary.html
{% load static %}
{% block content %}
<div class="row">
<p>123</p>
</div>
<div class="row">
{% for goal, compl_weight in corporate_goals %}
{{ goal.corp_goal_title }}
{% endfor %}
</div>
<div class="row">
<p>123</p>
</div>
{% endblock %}
Even If I copy all my code from corporate_goal.html into summary - I will have nothing. Why ?

I think that the problem is that your html structure has no sense. You have three {% block content %}. Please, delete the content blocks of your include files (corporate_goal.html and summary.html) and check if this is the problem. I think that one of your content block is overriding the other one.
Just to clarify, when you use the "include tag" is like you were pasting the code from other file. So imagine the result. You have a block content that contains two other block contents inside it.

My problem was in zip objects. When we are iterating through a zip object it is exhausted and you cannot iterate through it again. So, solution is corporate_goals = list(zip(corp_goals, compl_weight)). Anyway, thank you, #LaCharcaSoftware, for the advice, I've changed my structure to avoid duplication with block content.

Django paginator returning same data on seperate pages

Problem:
I am developing an application in django that uses paginator for the list page of a model, it is set to display 25 instances of the model per page, when i view the first page everything works fine but when i move to the second page it shows some values from the first again. i have checked the database and there is no data duplication either.
Cause/attempted solutions:
while not 100% i believe the problem originates from the order_by in the queryset but even after changing and removing the problem persists
Details:
snips of list for the first and second page
First: https://imgur.com/tyY5xu0
Second: https://imgur.com/UcGWEFN (note CO01, 4 and 5 appear again)
Views.py:
def view_jobs(request):
query_results = Job.objects.select_related('contract').order_by('-active', '-order_date')
paginate = Paginator(query_results, 25)
page_no = request.GET.get('page')
page_obj = paginate.get_page(page_no)
context = {"query_results": page_obj}
return render(request, 'view_jobs.html', context)
view_jobs.html:
<table id="PageTable" class="table table-striped">
<thead>
<tr>
<th class="dropdown">
<a class="dropdown-toggle" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true"
aria-expanded="false">
<h6>Number</h6>
</a>
</th>
</tr>
</thead>
<tbody>
{% for item in query_results %}
<td>
<small>{{ item|filter_prep:"order" }}</small>
{% if item.help_text %}
<small style="color: grey">{{ item.help_text }}</small>
{% endif %}
{% for error in item.errors %}
<p style="color: red">{{ error }}</p>
{% endfor %}
</td>
</tr>
{% endfor %}
</tbody>
</table>
<div class="pagination">
<span class="step-links">

Django how to forward django-filter URL named parameters

I'm new to django so i could be asking a dumb question, but how am i supposed to forward URL A's named parameter to URL B?
For example:
URL A = https://stackoverflow.com/questions?parameter=1
URL B = https://stackoverflow.com/ask
What i actually want is:
URL B = https://stackoverflow.com/ask?parameter=1
I need to do this because i need to pass those parameters to the view that is being called at the second url, could someone help me?
EDIT1
The views that are at play are this two:
class HostServiceListView(BaseFilterView, ListView):
template_name = 'services/service_list.html'
model = HostService
paginate_by = 15
context_object_name = 'services'
filterset_class = HostServiceFilterSet
def exportHostServices(request):
hsqs = HostService.objects.filter(hostname__icontains=request.GET.get("hostname_input", ''),\
ip__icontains=request.GET.get("ip_input", ''),\
port__icontains=request.GET.get("port_input", ''),\
servicename__icontains=request.GET.get("servicename_input", ''))
df = read_frame(hsqs)
# my "Excel" file, which is an in-memory output file (buffer)
# for the new workbook
excel_file = IO()
# pylint shows a false positive error here,
# so the alert is suppressed with the comment after the code
xlwriter = pd.ExcelWriter(excel_file, engine='xlsxwriter') # pylint: disable=abstract-class-instantiated
df.to_excel(xlwriter, 'Host Services')
xlwriter.save()
xlwriter.close()
# rewind the buffer
excel_file.seek(0)
# set the mime type so that the browser knows what to do with the file
response = HttpResponse(excel_file.read(),\
content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet')
# set the file name in the Content-Disposition header
response['Content-Disposition'] = 'attachment; filename=Anagrafica-Servizi.xlsx'
return response
The urls.py is configured this way:
urlpatterns = [
path('services/', HostServiceListView.as_view(), name='services'),
path('services/exportHostServices/', exportHostServices, name='exportHostServices'),
path('', IndexFilterView, name="index")
]
Finally, the button i've got in html that needs to call exportHostServices with the query-string so i can get the parameters:
services/service_list.html
{% extends 'services/base.html' %}
{% load paginatedfilter %}
{% block title %}Host Services{% endblock title %}

Figured out atlast what was wrong with the code. The problem was that the form where i passed the querystring was defaulted at GET:
<form action="{% url 'exportHostServices' %}?{{ request.GET.urlencode }}">
The fix was to simply convert it to a POST form so the querystring could be passed to the view:
<form action="{% url 'exportHostServices' %}?{{ request.GET.urlencode }}" method="post">

How to fix NoReverseMatch in django

I am developing an ecommerce website just for a practice and all the codes were working fine but all of a sudden I am getting a error at the django template
I have tried following most of the answers but none of it seems to working
This is my urls.py
urlpatterns = [
url(r'^$', views.cart_detail, name='cart_detail'),
url(r'^add/(?P<product_id>\d+)/$', views.cart_add, name='cart_add'),
url(r'^remove/(?P<product_id>\d+)/$', views.cart_remove, name='cart_remove'),

this is my main urls.py of the project
