Post and save Django variable, doesn´t work
0
could someone please check how should I write correctly the views.py part?
If I code:
from django.shortcuts import render, redirect
def shifts_table(request):
print(request.POST['value'])
return render(request, 'shifts_table.html', {})
...at least the page runs, but if I code like below it doesn't, any idea why?
from django.shortcuts import render, redirect
from django.contrib import messages
def shifts_table(request):
if request.method == 'POST':
number = request.POST['value']
if number.is_valid():
number.save()
return redirect('shifts_table.html')
else:
messages.success(request, ('Seems Like There Was An Error...'))
return render(request, 'home.html', {})
else:
return render(request, 'shifts_table.html', {})
home.html:
<form action="{% url 'shifts_table' %}" method='POST'>
{% csrf_token %}
<label for='number'>Number:</label>
<input type="number" name="value" placeholder="2020" required><br/>
<button type="submit">submit</button>
</form>
urls.py:
urlpatterns = [
path('', views.home, name='home'),
path('shifts_table', views.shifts_table, name='shifts_table'),
]

You can’t set a variable in one request and access it in another. You could save data in the session, or a cookie, or a cache, then refetch it in another view.

number = request.POST['value']
This will return a string and strings don't have a save method so it will not work
I think that you have a model that is referenced by that number and to save it to the database you can do something like this
object= yourmodel.objects.get(pk=number)
object.save()
Also strings don't have a definition for is_valid(), which is used in forms, which are not implemented in your view
After saving to the database you have to redirect, which is done only if nothing is submitted
Final code :
def shifts_table(request):
if request.method == 'POST':
number = request.POST['value']
# check if number is valid (not empty and no spaces before or after)
if not number.strip():
object = yourmodel.objects.get(pk=number)
object.save()
return render(request, 'home.html', {})
else:
messages.success(request, ('Seems Like There Was An Error...'))
return render(request, 'home.html', {})
else:
return render(request, 'shifts_table.html', {})

You can’t set a variable in one request and access it in another. You could save data in the session, or a cookie, or a cache, then refetch it in another view.
