How to get information from option field in django? - django

Question

I have django application with authentication and I have dropdown menu inside.
Before I did it like:
<select name="country" id="id_category" data="{{ data.country }}">
{% for each in living_countries_list %}
<option name="country" value="{{ each.0 }}" class="living_countries">{{ each.1 }}</option>
% endfor %}
</select>
And now I changed it to:
<input list="brow" placeholder="Search for your country..." class="input_country">
<datalist id="brow">
{% for each in living_countries_list %}
<option name="country" value="{{ each.0 }}" class="living_countries">{{ each.1 }}</option>
{% endfor %}
</datalist>
<p class="country_text">Please select your living country</p>
In my views.py file I passed context like:
country = request.POST.get('country')
professors = models.Professor.objects.all()
living_countries_list = LIVING_COUNTRIES
print(country)
In models.py I have options like:
LIVING_COUNTRIES = [
('AFGANISTAN', 'Afganistan'),
('ALBANIA', 'Albania'),
('ALGERIA', 'Algeria'),
('ANGORRA', 'Andorra'),
('ANGOLA', 'Angola')]
class Professor(models.Model):
country_living = models.CharField(max_length=50, choices=LIVING_COUNTRIES, default=FRESHMAN, blank=True, null=True)
So I have few options which are displayed either way but in changed I can type in input and that's what I want to be able to do.
If you want me to post anything else let me know in comments

You don't need to create forms with traditional methods in django. Create first FormSet in views.py:
from django.shortcuts import render
from . import models
from django.forms import modelformset_factory
def formpageview(request):
ProfessorFormSet = modelformset_factory(models.Professor, fields=('country_living',))
queryset = models.Professor.objects.filter(pk=1) # you can make the filter whatever you want it doesn't have to be that way
if request.method == 'POST':
formset = ProfessorFormSet(request.POST, request.FILES, queryset=queryset,)
if formset.is_valid():
formset.save()
# do something.
else:
formset = ProfessorFormSet(queryset=queryset,)
return render(request, 'form.html', {'formset': formset})
and then use this formset in form.html:
<form method="post">
{% csrf_token %}
{{ formset.management_form }}
{% for form in formset %}
{{ form }}
{% endfor %}
<button type='submit'>Submit</button>
</form>
