How to dynamically update the modified fields of a Model

Question

Let's say I have the model Project . The model Project has > 100 fields.

I can create new Projects from the front-End using forms.

When I want to edit/update some field of a Project in the back-end I've been doing something like this (truncated):

def edit_project(request):
    if request.method == 'POST':
        project_to_edit = Project.objects.get(pk=request.POST['project_id'])
        project_to_edit.description = request.POST['description']
        project_to_edit.name = request.POST['name']
        #repeat the same process for each field...(>50)
        project_to_edit.save()
        return redirect('project_page/')
    return redirect('index')

The problem is that new fields are constantly being added to the Projects model.

Is there a dynamic/ pythonic way to update each field in the model without having to do it 'manually' for each field and save lines of code?

Answer 1

You can update fields dynamically like that:

def edit_project(request):
    if request.method == 'POST':
        project_to_edit = Project.objects.get(pk=request.POST['project_id'])
        for field in self.fields:
            project_to_edit.description = request.POST[field]
            project_to_edit.name = request.POST[field]
            #repeat the same process for each field...(>50)
            project_to_edit.save()
        return redirect('project_page/')
    return redirect('index')

PS You should use form.cleaned_data to access your form data and not directly the submitted data. Modelform would solve your issues https://docs.djangoproject.com/en/4.0/topics/forms/modelforms/

I think this is the way to go.
