def valoare_list(request): 
    valoares = Valoare.objects.all 
    return render(request, 'contracte/valoare_list.html', {'valoares': valoares})

urls.py

from django.conf.urls import url 
from . import views 

urlpatterns = [ 
    url(r'^$', views.valoare_list, name='valoare_list'), 
    url(r'^valoare/(?P<pk>\d+)/$', views.valoare_detail, name='valoare_detail'), 
    url(r'^contract/(?P<valoare>[a-z]{4})/(?P<pk>\d+)/$', views.contract_list, name='contract_list'), 
] 

Answer 1

あなたはこの貫通tip_valoare渡しているので：<a href="{% url 'contract_list' valoare=valoare.tip_valoare pk=tip.pk %}">を、その後、URL url(r'^contract/(?P<valoare>[a-z]{4})/(?P<pk>\d+)/$', ...)内部valoare値は、tip_valoare（4小文字になります大文字と小文字）。

その後、あなたは（contract_listビュー内の）このようなvaloareオブジェクトを取得することができます

def contract_list(request, valoare, pk): 
    # (?????) - valoare is actually the tip_valoare 
    valoare = get_object_or_404(Valoare, tip_valoare=valoare) 
    tip = get_object_or_404(Tip, pk=pk) 
    return render(request, 'contracte/contract_list.html', {'valoare': valoare, 'tip': tip})
