Deploy Heroku

Oii Raul, como você está?

Quando você executa o comando, quais são os logs de erro? Cole-os aqui por favor.

Fico no aguardo para te ajudar, tá bom?

É bem grande. Mas vou mandar. Um momento, acabei deletando o APP. Vou refazer.

Nesse caso eu separei o settings em 2: base.py e heroku.py, entretanto não configurei as variáveis de ambiente, então o heroku deve ler a variável de ambiente do base.py

O deploy até entra, mas o que não vai é na hora de rodar :

heroku run python manage.py migrate 

Meu código ta no github mas tá privado... se puder me ajudar eu coloco você como colaboradora para ter acesso ao código. Não consigo achar o erro de jeito algum.

Da o seguinte erro:

    raise ValueError('Related model %r cannot be resolved' % self.remote_field.model)
ValueError: Related model 'alunos.instrutor' cannot be resolved

Acho que consegui consertar esse primeiro erro usando o caminho relativo na pasta: migrations/0001__initial.py

Usei a seguinte notação:

('instrutor',models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, to='apps.alunos.instrutor')),

As migrações estavam indo bem até que apareceu esse segundo erro:

ValueError: too many values to unpack (expected 2)

Oii Raul, segundo o log de erro ValueError: too many values to unpack (expected 2) é porque em algum momento a função split está retornando mais ou menos de 2 elementos, porém o esperado é exatamente dois. Tente o seguinte:

• Vá nos arquivos apps.py dos todos os seus apps, por exemplo: há um app chamado usuarios, vá até o arquivo apps.py dele:
  • Você irá encontrar algo como:

from django.apps import AppConfig


class UsuariosConfig(AppConfig):
    name = 'usuarios'
    label = "users"

• Verifique se o valor do atributo label possui um ponto (.), por exemplo: label = 'my.users' e caso contenha, retire esse ponto. E tente compilar novamente.

Caso ainda não resolva, fique tranquilo, a gente vai se falando.

No caso, nenhum deles tem o atributo label. Todos os Apps só tem o name.

Consegui fazer o Deloy finalmente... a solução foi a seguinte:

                ('matricula', models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, to='alunos.Matricula')),

A syntax no migrations tem que ser a seguinte: nome do app em minusculo e nome da tabela em Maiusculo

Exemplo: alunos.Matricul

Que bom que conseguiu. Vendo os trechos anteriores de códigos que você disponibilizou eu não consegui identificar. Estava te escrevendo para você compartilhar o código comigo. Mas, fico extremamente feliz que tenha conseguido achar a solução. Mandou super bem, parabéns!

Grande abraço!

Foi um pouco de sorte rsrs, vi uma resposta na internet sobre esse assunto... Já tinha visto pelo menos umas 15 respostas diferentes e nenhuma deu certo. Aí nessa... Consegui hahaha e era tão simples. Qualquer problema futuro, que eu precisar de ajuda, basta me passar seu git que eu compartilho a versão com voceê sem problemas... E obrigado por mais uma vez estar tentando me ajudar! Aprendendo muito e muito satisfeito com a Alura e sua equipe! Será que fico rico? Hahaha
