Error Using django-tables2 - Expected table or queryset, not 'str'

问题

I am trying to create some tables for my application using django-tables2 and running into some difficulties. I am using Python 2.7, and Django 1.7. I am following the tutorial, and I ran into problems.

I reach the point where I need to create a Table class for customization. However, whenever I do so, I get the following error:

Expected table or queryset, not 'str'.

After doing some research it looks like I am using an older version of django-tables2. However, I just installed it yesterday using pip install django-tables2 and updated it a half an hour ago. Any idea how I can get django-tables2 to work properly?

EDIT - Problem solved. I was using {% render_table people %} instead of {% render_table table %}

I encountered that problem, too. The first thing you should do is to check your updates.
sudo pip install django-tables2 --upgrade
sudo pip install django-tables2-reports --upgrade
Upgrades didn't work mine problem too.
If you have already upgraded version of these. You should check your implementation. If you are using Class Based View and you are pretty sure that you implement the view,template,table. You must probably forget the urls.
So urls should look like this.

/* I give the example with respect to other post*/
urls.py  /*Same dic with table.py,models..etc*/
from .views import SomeTableView   
urlpatterns = patterns('',
                   url(r"^$", SomeTableView.as_view(), name="index"),


                   )

If it is not index of your website you have to probably change the r"^$" and name="index"

Well I think your problem isn't with the version of django-tables2. Here I think when you are passing a variable from view to template, you are passing a string instead of a queryset/table class object. For working example:

Table class:

class SomeTable(tables.Table):

    class Meta:
        model= SomeModel
        attrs = {"class": "paleblue"}

View Class:

class SomeTableView(SingleTableView):
    model = SomeModel
    template_name = 'test.html'
    table_class = SomeTable

Template:

 {% load render_table from django_tables2 %}
 {% render_table table %}   <!-- Here I am passing table class -->

Or you can directly send a queryset to render the table like:

class SomeView(TemplateView):
     def get(self, request, *args, **kwargs):
         data = SomeModel.objects.all()
         context = self.get_context_data(**kwargs)
         context['table'] = data
         return self.render_to_response(context)

and render it like this:

{% load render_table from django_tables2 %}
{% render_table table %} <!-- Here I am passing queryset -->

Had the same problem. I forgot to add SingleTableMixin in the parameters of the view class
