Значения набора запросов Django, которые будут изменены и отправлены пользователю в виде простой текстовой копии

Question

Это мой код, который может отправлять текстовый файл пользователю со всеми результатами набора запросов, но требуется выравнивание результатов путем удаления символов.

def save_search(request,q="deve"):
   filename = "mytext.txt"
   content =Buildkb.objects.values("text","knowledge","created_by_email").
               filter(Q(knowledge__icontains=q)|Q(text__icontains=q))
   response = HttpResponse(content, content_type='text/plain')
   response['Content-Disposition'] = 'attachment; filename{0}'.format(filename)
return response

вывод: -

Answer 1

Ответ Jitendra является правильным, но имейте в виду, что альтернативой является использование render () для рендеринга шаблона, который получает ваш контент в качестве контекста.

Затем вы можете выполнить форматирование в шаблоне, и это может дать вам большую гибкость при форматировании выходных данных, чтобы они хорошо выглядели на отображаемой странице.

Answer 2

В REST framework доступно несколько рендеров.Если вы хотите получить простой текстовый ответ, создайте пользовательский рендер.

from django.utils.encoding import smart_unicode
from rest_framework import renderers


class PlainTextRenderer(renderers.BaseRenderer):
    media_type = 'text/plain'
    format = 'txt'

    def render(self, data, media_type=None, renderer_context=None):
        <<Write your custom code here>>
        return data.encode(self.charset)
