module = importlib.import_module('example.submodule') module.__all__with __all__ you have the same logic of *

{% if len(article.body) > 50 %} <p>{{ article.body }} <a href="#">read more</a></p> {% else %} <p>{{ article.body }}</p> {% endif %}

Use for loop before if

Anonymous

{% for body in article %} {% if len(body)>50 %} {{ body }} {% endif %} {% endfor %}

Jimmies San

{% for body in article %} {% if len(body)>50 %} {{ body }} {% endif %} {% endfor %}

filters are better , like truncate https://docs.djangoproject.com/en/2.0/ref/templates/builtins/#truncatewords

Jimmies San

Use for loop before if

and btw the if doesn't impact on performance, a loop... it does.

Have you connected to a database?

Meera

Have you connected to a database?

i dont know

Meera

how can i connect it ?

Meera

DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'forlotus', 'USER': 'postgres', 'PASSWORD': 'admin', 'HOST': '127.0.0.1', 'PORT': '5432', } }

Meera

my database dictionary in settings.py

Mounikesh

see try installing dj_database_url in your django virtual environment

Mounikesh

import dj_database_url ENVIRONMENT = 'production' DEBUG = False ALLOWED_HOSTS = ['yourapp.herokuapp.com'] DATABASES['default'] = dj_database_url.config( default='DATABASE_URL_HERE' )

Mounikesh

and add this to your setting file

Meera

import dj_database_url ENVIRONMENT = 'production' DEBUG = False ALLOWED_HOSTS = ['yourapp.herokuapp.com'] DATABASES['default'] = dj_database_url.config( default='DATABASE_URL_HERE' )

DATABASES['default'] = dj_database_url.config( default='DATABASE_URL_HERE' ) can i directly copy paste it ? or should i knwo my 'DATABASE_URL' ...and if so.. how can i know my database url

Mounikesh

directly copy paste

Mounikesh

DATABASE_URL is automatically added by Heroku upon PostgreSQL database installation. So after this you need need to add the SECRET_KEY:

https://simpleisbetterthancomplex.com/tutorial/2016/08/09/how-to-deploy-django-applications-on-heroku.html

Meera

directly copy paste

done....re deployed...same error

Mounikesh

i guess the error might be from django app not on the heroku side ,ok post the error log file and did you run migrate command

Mounikesh

in case of url mismatch

Mounikesh

then this should be the error

Mounikesh

Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/api/status
