Question

I’m trying to get data by id in my django app. The problem is that I don’t know the kind of id the user will click on. I tried adding the below code in my views but I’m getting this error:

 ValueError at /findme/

 invalid literal for int() with base 10: 'id'

 Request Method:    GET
 Request URL:   http://127.0.0.1:8000/findme/
 Django Version:    1.4
 Exception Type:    ValueError
 Exception Value:   invalid literal for int() with base 10: 'id'

 Exception Location:    C:\Python27\lib\site-packages\django\db\models\fields\__init__.py in get_prep_value, line 537
 Python Executable:     C:\Python27\python.exe
  Python Version:   2.7.3

Views

from meebapp.models import Meekme

def cribdetail(request):
    post=Meekme.objects.get(id='id')
    return render_to_response('postdetail.html',{'post':post, 'Meekme':Meekme},context_instance=RequestContext(request))

What I’m I missing?

Answer 1

The problem is that 'id' is a string and you need to pass an integer here:

post=Meekme.objects.get(id='id')

It should most likely look like this:

def cribdetail(request, meekme_id):
    post=Meekme.objects.get(id=meekme_id)
    return render_to_response('postdetail.html',{'post':post, 'Meekme':Meekme},context_instance=RequestContext(request))

where meekme_id is an integer that is part of the URL. Your URL configuration should contain:

url(r'^example/(?P<meekme_id>\d+)/$', 'example.views.cribdetail'),

When you visit example/3/, that means Django will call the view cribdetail with the value 3 assigned to meekme_id. See the Django URL documentation for more details.
