Hi im trying to redirect from one view function to another and passing a list of lists as argument.
urls.py
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^checkFiles/', views.checkFiles, name='checkoutFiles'),
url(r'^$', views.home, name='home'),
url(r'^upload/', views.upload, name='upload'),
url(r'^login', views.loginview, name='loginview'),
url(r'^logout/', views.logoutview, name='logoutview'),
url(r'^confirm_files/', views.upload, name='confirm_file'),
url(r'^upload/', views.del_files, name='del_files'),
]
views.py
for redirecting from views.upload to views.checkoutFiles i'm using this command
return redirect(reverse('checkoutFiles', kwargs={'ACCEPTED_FILES':ACCEPTED_FILES}))
...
def checkFiles(request, ACCEPTED_FILES):
print ACCEPTED_FILES
return render(request, 'confirm_files.html', {
'ACCEPTED_FILES': ACCEPTED_FILES
})
and im getting this error message
NoReverseMatch: Reverse for 'checkoutFiles' with keyword arguments '{'ACCEPTED_FILES': [[u't2_r0Oqwl7.txt', '0.98 KB', u'text/plain']]}' not found. 1 pattern(s) tried: ['checkFiles/']
django version: 1.11.2
When you call reverse, Django follows what you have in urls.py. In there you don't have any parameters specified in the regular expression for checkoutFiles. For example:
url(r'^articles/([0-9]{4})/$', views.year_archive, name='year-archive'),
In this example you can call:
reverse('year-archive', args=[datetime.datetime.today().year])
https://docs.djangoproject.com/en/1.11/topics/http/urls/#example
In your code you must specify what are the parameters you'll receive in that URL.
url(r'^checkFiles/(?P<extension>[\w]+)/$', views.checkFiles, name='checkoutFiles'),
Although it would not be a good idea doing this kind of validation through a URL.
If you want to have something in the URL, you can use a GET parameter:
Whenever you redirect you can do something like this:
return redirect(reverse('checkoutFiles') + '?files={}'.format(ACCEPTED_FILES))
In the view where you are redirected to, you can get the values with
request.GET.get('files', '')
