python - Reverse for '' with arguments '()' and keyword arguments not found. Django -


i have been having trouble few dayss , havent been able find answers. want url / in if print want /print.

i understand regex wrong , need changed, here code.

myproject/urls.py

url(r'^(?p<pk>)/$', views.page_detail, name='page_detail'),

it throws error on line 5 function_list.html

{% extends 'wiki/base.html' %}  {% block content %} {% page in pages %}     <h1><a href="{% url 'page_detail' pk=page.pk %}">{{ page.function }}</a></h1>     <p>{{ page.usage|linebreaksbr }}</p> {% endfor %} {% endblock %}

views.py

def page_detail(request, pk):     page = get_object_or_404(page, pk=pk)     return render(request, 'wiki/page_detail.html', {'page': page})

page_detail 

{% extends 'wiki/base.html' %}  {% block content %} <h1>{{ page.function }}</h1> <p>{{ page.usage|linebreaksbr }}</p>  {% endblock %}

the specific error 

reverse 'page_detail' arguments '()' , keyword arguments '{'pk': 'print'}' not found. 1 pattern(s) tried: ['page/(?p<pk>)/$']

if has ideas or resources me @ appreciate it.

edit: include page model

models.py

class page(models.model):     function = models.charfield(max_length=100, primary_key=true)     usage = models.charfield(max_length=200)     author = models.charfield(max_length=100)     library = models.charfield(max_length=100)     parameters = models.textfield()     returnvalues = models.charfield(max_length=100)     examples = models.textfield()     notes = models.textfield()     seealso = models.textfield()

from question, seems have more 1 url points view. so, remove duplicate url. if that's not issue make sure passing "object id" correctly through url. "object id" (?p<pk>\d+) required parameter in url detailview.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
