django - How do I change the template being displayed after the user clicks a button? -

i'm quite new django, aplogize if making dumb mistakes.
here code have far:

for views.py:

def bylog(request):     if request.post.get('filter'):         return render(request, 'index.html', context)     filtered_login = invalid.objects.values_list('login').distinct()     filtered = []     item in filtered_login:         filtered.append(item[0])     results = {'results': results, 'filtered': filtered}     return render(request, 'bylog.html', context) 

here snippet of bylog.html:

<select id>"dropdown"> {% item in filtered %}     <option value={{ item }}">{{ item }}</option> {% endfor %} </select> <input type="submit" value="filter" name="filter" /> 

my main goal value drop down list, , after user clicks filter button, value gets passed template.
possible?

thanks help.

the basic goal supose manage post in django, meaning want send data/variables template view , operation (send template, or store...)

the basic is(using html form, not django form):

- create html form in template  - add selects/inputs data want manage , button/input make post - manage post in view 

example

template form

<form id="" method="post" action="."> {% csrf_token %} <select id="any_name" name="any_name">"dropdown"> {% item in filtered %}     <option value={{ item }}">{{ item }}</option> {% endfor %} </select> <input type="submit" value="filter" name="filter" />  </form> 

view.py

def your_view(request):     if request.method == 'post':  # if clicks filter, receive post method         data = request.post['any_name']         # need here data         # can call template , send data         # can change any_name variable want, changing name , id in select  #your view code 

i recommend read django forms because if need bigger form, manage data of model lot of fields, django form save lot of time

working django forms
