模板中的Django渲染HTML提供字节

Question

In my django application, I am manually rendering a page and giving it to a template to include :

def get_context_data(self, **kwargs):
    page = render(self.request, test_absolute_path, context, content_type=None, status=None, using=None)
    soup = BeautifulSoup(page.content, 'html.parser')
    soup.dosomestuff()
    page.content = str(soup.decode()).replace('\n','')
    context['subtests'].append(page)
    return context

Then including the rendered HTML into a template using the safe tag :

 {{ page.content | safe }}

I do have my tags included but the text appears like a bytearray and the encoding isn't right for some reason :

b'
My text Cat\xc3\xa9gorisation S\xc3\xa9quqsdazeences R\xc3\xa9ponses associ\xc3\xa9es Fluidit\xc3\xa9 

Notice that I also had to replace all \\n with nothing in the code.

EDIT :

I noticed that encoding the soup in ascii at least prints all the characters, I still can't get rid of the \\n or b though :

page.content = soup.encode('ascii')

The page.content always returns byte array. One option is to call decode in template tag.

{{ page.content.decode | safe }}

Another one is to use different name like below.

def get_context_data(self, **kwargs):
    page = render(self.request, 'viewbase/sub_page.html', context,
            content_type=None, status=None, using=None)
    soup = BeautifulSoup(page.content, 'html.parser')
    soup.dosomestuff()
    page.new_content = soup.decode()
    context['subtests'].append(page)
    return context

With that, the template has below tag.

{{ page.new_content | safe }}

Or directly put content instead of page in context in case you don't need anything else from the page.

    context['subtests'].append(soup)

{{ soup | safe }}
