Referring to the Django docs:
https://docs.djangoproject.com/en/3.2/intro/tutorial03/#a-shortcut-render
from django.shortcuts import render
from .models import Question
def index(request):
latest_question_list = Question.objects.order_by('-pub_date')[:5]
context = {'latest_question_list': latest_question_list}
return render(request, 'polls/index.html', context)
Edited for your model
from django.shortcuts import render
from .models import VDSTARIFS
def vds(request):
ALL_VDSTARIFS = VDSTARIFS.objects.all()
FIRST_VDSTARIF = ALL_VDSTARIFS[:1]
# Get prise
prise = FIRST_VDSTARIF.prise
# Alternatives to print 'prise' in template
# Pass only the first item of vds list
context = {
"FIRST_VDSTARIF": FIRST_VDSTARIF
}
# Pass prise only
context = {
"prise": prise
}
# All records in html also the needed one in separated item
context = {
"ALL_VDSTARIFS": VDSTARIFS,
"FIRST_VDSTARIF": FIRST_VDSTARIF
}
return render(request, 'vds.html', context)
}
In template you can use if
https://docs.djangoproject.com/en/3.2/ref/templates/builtins/#if
{# Runs along all tarifs and print only one, not good. #}
{% for vdstarif in ALL_VDSTARIFS %}
{% if vdstarifs.id == "1" %}
{{ vdstarif.prise }}
{% endif %}
{% endfor %}
{# Only print the needed one #}
{{ FIRST_VDSTARIF.prise }}
{# Print prise #}
{{ prise }}
You might follow python and django coding conventions and my suggestions.
Rename VDSTARIFS -> VdsTarif (look at your admin page, Django adds 's' to your model to make it plural)
Use singular names for your models and add a suffix to variable names in views like vdstarif_list.
For "prise" field use DecimalField, looks like it is a CharField. Is it prise or price?
https://docs.djangoproject.com/en/3.2/ref/models/fields/#decimalfield
from django.shortcuts import render
from .models import VdsTarif
def vds(request):
vdstarif_list = VdsTarif.objects.all()
context = {
"vdstarif_list" : vfstarif_list[:0].prise
}
return render(request, 'vds.html', context)
