Re: global name 'content' is not defined

Hi

From the traceback the error is in :-

def view_page(request, page_name):
       try:
               page = Page.objects.get(pk=page_name)
       except Page.DoesNotExist:
               return render_to_response("create.

html",{"page_name":page_name})
       return render_to_response("view.html", {"page_name":page_name,
"content":content},context_instance=RequestContext(request))

Before looking further make sure everything is imported correctly.

Now, It is not able recognize content,  what is content ? 

You should do content = page.content and then assign  a key named 'content' : content just like you had.

Page is a class and content,name are its attributes.

so when you do this :-

page = Page.objects.get(pk=page_name)

# You are making a query from the Page table that will return something , page_name you are already passing it as an argument (don't know how) that's why it is not throwing an error but for content , it is an entity/attribute of page .

So make an object of that class Page and then access its attributes.

I am also not an expert in django but i think this info might help you.
