DjangoRest

Test Status

Esse projeto consiste em um CRUD de produtos.

Primeiramente, clone o projeto. Instale python3 e pip. É aconselhado fazer isso em uma virtualenv.

Requisitos

  • Python 3.6.7
  • pip 19.0.1 (python 3.6)

Obs: todos os comandos a seguir devem ser executados na raiz do projeto (diretório products).

Install

sudo apt install curl
sudo apt install httpie
make setup

Durante o setup será solicitado nome de usuário, email e senha, que serão usados para fazer login no sistema.

Documentação

make showdoc

Está configurado para abrir no Firefox. Caso não tenha instalado, você pode consultar a documentação abrindo esse arquivo: djangoRest/doc/_build/html/index.html

Testes

make test

Como executar

make run
  • Pelo navegador

Acesse http://127.0.0.1:8000. Você irá se deparar com a seguinte imagem:

https://github.com/alynnefs/testeConceptu/blob/master/img/01.png

Note que em detail há a mensagem "Authentication credentials were not provided". Isso acontece porque você não está logado.

https://github.com/alynnefs/testeConceptu/blob/master/img/02.png

Após se logar, aparecerá o link http://127.0.0.1:8000/products/. Você pode clicar nele ou adicionar products/ na barra de endereço.

Obs: se você não estiver logado, por mais que mude o link pela barra de endereço, continuará aparecendo a mensagem "Authentication credentials were not provided".

https://github.com/alynnefs/testeConceptu/blob/master/img/03.png

Após clicar no link, aparecerá essa tela de listagem de produtos. Como ainda não adicionamos nenhum produto, "results" está vazio.

https://github.com/alynnefs/testeConceptu/blob/master/img/04.png

Você pode adicionar produtos através desse formulário:

https://github.com/alynnefs/testeConceptu/blob/master/img/05.png

A seguir temos o resultado da adição:

https://github.com/alynnefs/testeConceptu/blob/master/img/06.png

Você pode adicionar quantos produtos quiser.

https://github.com/alynnefs/testeConceptu/blob/master/img/07.png

Se você clicar, por exemplo, em http://127.0.0.1:8000/products/1, é possível editar o produto selecionado.

https://github.com/alynnefs/testeConceptu/blob/master/img/08.png

Lista de produtos depois da edição:

https://github.com/alynnefs/testeConceptu/blob/master/img/09.png

Na tela de edição também é possível excluir.

https://github.com/alynnefs/testeConceptu/blob/master/img/10.png

Vamos excluir o produto2 (http://127.0.0.1:8000/products/2) clicando no botão "delete".

https://github.com/alynnefs/testeConceptu/blob/master/img/11.png

Após confirmar, o produto2 não estará mais presente na lista de produtos.

https://github.com/alynnefs/testeConceptu/blob/master/img/12.png

Adicionei mais dois produtos para mostrar o funcionamento dos filtros.

https://github.com/alynnefs/testeConceptu/blob/master/img/13.png

Nomes ordenados de forma crescente:

https://github.com/alynnefs/testeConceptu/blob/master/img/14.png

O resultado está a seguir:

https://github.com/alynnefs/testeConceptu/blob/master/img/15.png

Também é possível procurar por nome.

Outros exemplos de obtenção de dados sem GET:

  • Pelo terminal com curl

http://127.0.0.1:8000/

$ curl -H 'Accept: application/json; indent=4' http://127.0.0.1:8000/
{
    "detail": "Authentication credentials were not provided."
}

http://127.0.0.1:8000/products/

$ curl -H 'Accept: application/json; indent=4' http://127.0.0.1:8000/products/
{
     "detail": "Authentication credentials were not provided."
}

http://127.0.0.1:8000/products/1/

$ curl -H 'Accept: application/json; indet=4' http://127.0.0.1:8000/products/1/
{
    "detail": "Authentication credentials were not provided."
}

Observe que todos possuem a resposta "Authentication credentials were not provided". Isso acontece porque não há nenhum usuário logado. Vamos usar usuário e senha criados no setup. Nesse exemplo, o usuário é "alynne" e a senha é "123456".
