Question

Traceback (most recent call last):
File "manage.py", line 23, in <module>

ModuleNotFoundError: No module named 'djangosige.configs.configs'

This is my configs.py file

# Configuração da base de dados

# Caso seja deixado vazio o default será: 'sqlite:////...djangosige/db.sqlite3'
DEFAULT_DATABASE_URL = 'postgres://meuuser:minhasenhadbc@localhost/nomebd'

# Configurações do servidor de email

# Endereço de email padrão utilizado

DEFAULT_FROM_EMAIL = '[email protected]'

EMAIL_HOST = 'smtp.gmail.com'  # Gmail
# EMAIL_HOST = 'smtp.live.com' #Hotmail

# Usuário do email padrão
EMAIL_HOST_USER = 'meuuser'

# Senha do email padrão
EMAIL_HOST_PASSWORD = 'minhasenha'

# Verificar a port utilizada pelo serviço de email
EMAIL_PORT = 587

EMAIL_USE_TLS = True

Does anyone know what might be going on?

Answer 1

I would indicate using an api for postgresql dj-database-url and configure the email server in the same directly in the Settings.
For me never gave problems!

import dj_database_url

    DATABASES = {
        'default': dj_database_url.config()
    }

EMAIL_BACKEND ='Django.core.mail.backends.console.Emailbackend'

EMAIL_HOST =""
EMAIL_HOST_USER = ""
EMAIL_PORT = 3386
EMAIL_USER_TLS = True
EMAIL_HOST_PASSWORD = ""
DEFAULT_FROM_EMAIL = ""

Answer 2

Interpreting the error message:

You have the module:

/app/djangosige/configs/__init__.py

On line 3 of this file Voce makes an import

from .settings import *

That runs successfully, with the asteriskVoce imports everything implicitly, practice not recommended by PEP 20 (Explicit is Better than implicit.), in that import the file settings.pyis loaded and in its line 4 vc makes import:

from .configs import DEFAULT_DATABASE_URL, DEFAULT_FROM_EMAIL,....

That is, Voce this in /app/djangosige/configs/making import of the config module that does not exist. Hence the error message: No module named 'djangosige.configs.configs'
