[Answer]-How do I use the same render in 2 separate view functions? (django)

Class based views are a pretty good option, but there is no reason you can’t do something like;

def _render(request, form):
    return render(request, 'projects/project_list.html', 
                  {"form": form, 'projects': request.user.project_set.all()})

@login_required
def project_list(request):
    projects = request.user.project_set.all()
    form = ProjectForm()
    return _render(request, form)

@login_required
def new_project(request):
    form = ProjectForm()
    if request.method == 'POST':
        form = ProjectForm(data=request.POST)
        if form.is_valid():
            project = form.save(commit=False)  #must specify user before commit
            project.owner = request.user
            project.save()
            return redirect(project)

    return _render(request, form)
