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.
