1o - Primeiras configurações de ambiente e add template base do Django em estrutura para docker-compose
python3 -m venv venv [PASTA VAI SER IGNORADA PELO GIT]
pip freeze
pip install pip --upgrade
pip install django
pip freeze [3 items]
sudo apt install python3-django
mkdir djangoapp [Vai ser a raiz do projeto django]
cd djangoapp
django-admin startproject project . [VAI ADD O TAMPLATE BASE DO DJANGO]
cd ..
python manage.py [vai ser]-> python3 djangoapp/manage.py runserver
-------------------------------------------------------------------------------------------------------------------------------
2o - Add dependencias inicias do python para o docker e remove boilerplate do dbsqlite.
rm -r ./djangoapp/project/db.sqlite
cd ./djangoapp
Cria o requirements.txt com:
Django>=4.2.1,<4.3
psycopg2-binary>=2.9.6,<2.10 [DRIVER DO POSTGRE]
-------------------------------------------------------------------------------------------------------------------------------
3o - variáveis de ambiente dotenv-files
mkdir dotenv-files && cd ./dotenv-files
Cria o .env com as constantes que vão ser utilizadas no settings.py do Django.
Cria a secretkey [NÃO VOU UTILIZAR]
cd djangoapp/project
Ajustes no settings.py puxando as variáveis constantes do .env (JÁ PENSANDO NA ESTRUTURA DE DIR PARA DOCKER)
Ajustes no urls.py deixando linear com o settings.py (JÁ PENSANDO NA ESTRUTURA DE DIR PARA DOCKER)
-------------------------------------------------------------------------------------------------------------------------------
4o - configurações do dockerfile e scripts bash para ser executado no processo de montagem da imagem no container
-------------------------------------------------------------------------------------------------------------------------------
5o - docker-compose
Cria o docker-compose.yml com as configurações para ambos os Dockerfiles
primeira vez: sudo docker-compose up --build
VAI DAR ERROS POR CONTA DA CONSTANTE POSTGRES_HOST DEFINIDA NO `.env` NO DIR dotenv-files
- Isso ocorre pois o host no docker não é localhost e sim o nome do container.
docker stop all: sudo docker stop $(sudo docker ps -a -q) ; sudo docker system prune -f ; sudo docker rm -vf $(sudo docker ps -aq) ;
docker remove all: sudo docker stop $(sudo docker ps -a -q) ; sudo docker system prune -f ; sudo docker rm -vf $(sudo docker ps -aq) ; sudo docker rmi -f $(sudo docker images -aq) ;
docker-compose up --build --force-recreate
OBS: TODA VEZ QUE ALTERAR OS ARQUIVOS DE CONFIGURAÇÃO DO DOCKER EM GERAL, DEVE-SE REMOVER CACHE E RE-BUILDAR COM
docker-compose up --build --force-recreate
- APENAS QUANDO FOR ARQUIVOS DOCKER, PARA ARQUIVOS EM GERAL DE DESENVOLVIMENTO ELE JÁ REFLETE AS MUDANÇAS COPIANDO ELAS PARA O CONTAINER.
ERRO DE PERMISSÃO AO BUILDAR, MESMO EXECUTANDO COM SUDO:

6o - Primeira rota com retorno view (HELLO WORLD)
docker-compose run djangoapp python manage.py startapp hello_world
VAI CRIAR O TEMPLATE BASE PARA A CRIAÇÃO DE ROTAS:
mkdir ./djangoapp/hello_world/templates/hello_world
cd ./djangoapp/hello_world/templates/hello_world
Cria o index.html desta rota com boilerplate `!`
cd ./djangoapp/hello_world/
Editar `views.py` definindo a função que retorna o ./djangoapp/hello_world/templates/hello_world/index.html
Copiar o `./djangoapp/project/urls.py
Remove boilerplates e deixa clean.
Editar `./djangoapp/project/urls.py` e add a rota do novo template hello_world

Retornando apenas o item JsonArray do json <script id='params'>, pois o json completo é muito poluído e dificil de entender quais membros são relevantes, como a ideia é após a análise concatenação item a item com `https://www.in.gov.br/en/web/dou/-/` + `jsonArray['urlTitle']`, então estou manipulando apenas o objeto interno jsonArray{...}

-------------------------------------------------------------------------------------------------------------------------------
11o - ScraperAPI: Add endpoint GET http://127.0.0.1:8000/trigger_web_scraping_dou_api/?data=`
- Obs1: Ainda não salvando em banco, vou implementar uma flag `?saveInDBFlag=true` depois.
- Obs2: Retorno sem paginação por enquanto.
- Já fazendo algumas validações no validator especializado.
-------------------------------------------------------------------------------------------------------------------------------
12o - ScraperAPI: Add logs em arquivo para os validators, não é boarat pica ficar expondo detalhes de erros para o mundo externo quando não existe autenticação e autorização.
-------------------------------------------------------------------------------------------------------------------------------
13o - ScraperAPI: Add endpoint GET http://127.0.0.1:8000/trigger_web_scraping_dou_api/?secao=do1|do2|do3&data=DD-MM-AAAA`
- Obs1: Ainda não salvando em banco, vou implementar uma flag `?saveInDBFlag=true` depois.
- Obs2: Retorno sem paginação por enquanto.
- Já fazendo algumas validações no validator especializado, e logger nos erros.
-------------------------------------------------------------------------------------------------------------------------------
14o - ScraperAPI: Comaça a implementar a `?saveInDBFlag=true` para cada um dos enpoints:
Varre tudo da home do https://www.in.gov.br/leiturajornal <--------- PARA ESTE PRIMEIRO
- GET http://127.0.0.1:8000/trigger_web_scraping_dou_api/?saveInDBFlag=true
Varre os DOU da seção mencionada na data atual
- GET http://127.0.0.1:8000/trigger_web_scraping_dou_api/?secao=`dou1 | dou2 | dou3`?saveInDBFlag=true
Varre os DOU da data mencionada
- GET http://127.0.0.1:8000/trigger_web_scraping_dou_api/?data=`DD-MM-AAAA`?saveInDBFlag=true
Varre os DOU da seção mencionada e na data mencionada
- GET http://127.0.0.1:8000/trigger_web_scraping_dou_api/?secao=`dou1 | dou2 | dou3`&data=`DD-MM-AAAA`?saveInDBFlag=true
Modificações em geral nas funções para não fazer duplicatas.
Adicionando a variável bool `saveInDBFlagURLQueryString` do parâmetro URL query string `?saveInDBFlag=true` para o handler genérico - GET http://127.0.0.1:8000/trigger_web_scraping_dou_api/ que faz a requisição crua sem parametros. Ou seja, getAll
REQUISIÇÃO: GET http://127.0.0.1:8000/trigger_web_scraping_dou_api/?saveInDBFlag=true
Varre tudo da home do https://www.in.gov.br/leiturajornal e salva no banco.
-------------------------------------------------------------------------------------------------------------------------------
14o - Database DOU API: Após utilizar a API especializada para os gatilhos na raspagem, resolvi criar outra ROTA especializada em fazer as requisições para o banco local, ou seja, não implementar na mesma API especializada em raspagem para maior coesão.
- Essa ROTA `db_dou_api` faz requisições para a mesma tabela alimentada pelos triggers da `trigger_web_scraping_dou_api`
- Ou seja, utilizamos uma API para fazer os disparos das raspagens e se quiser alimentamos o banco.
- E Posteriormente, podemos acessar via outra ROTA esses dados já armazenados no banco local.
- OBS: Ainda não faz verificações para evitar duplicatas de registros!! Ou seja, toda vez que executar o gatilho GET http://127.0.0.1:8000/trigger_web_scraping_dou_api/?saveInDBFlag=true vai appender os mesmos registros no insert into..
- SOLUÇÃO QUE VOU IMPLEMENTAR PARA EVITAR DUPLICATAS: Utilizar o atributo "urlTitle": "resolucao-re-n-95-de-10-de-janeiro-de-2024-537019492" como chave primária.
- MELHOR SOLUÇÃO VISANDO PERFORMANCE: Antes de fazer a raspagem e salvar, verificar se já possue registros no banco local da data mencionada, e verificar se a quantidade de registros é a mesma no portal do DOU, desta forma, só iriamos inserir novamente a diferença entre os dois conjuntos.
-------------------------------------------------------------------------------------------------------------------------------
15o - Altera a chave primária da entidade JournalJsonArrayOfDOU utilizando o attr `urlTitle` pois ele é único, desta forma não vão ocorrer duplicatas (DISTINCT) de registros quando disparado os triggers de raspagem várias vezes.
[models.JournalJsonArrayOfDOU]:
urlTitle = models.CharField(max_length=255, primary_key=True, unique=True)
docker exec -it psql psql -U CHANGE-ME -d db_poder360

PRONTO, SÓ ESTÁ SALVANDO A DIFERENÇA ENTRE OS DOIS CONJUNTOS.
-------------------------------------------------------------------------------------------------------------------------------
16o - Como foi alterado a chave primária do JournalJsonArrayOfDOU para `urlTitle`, refletiu problemas em outras partes do código: Isso ocorreu pois o django rest framework utiliza o atributo id para algumas tarefas de controle interno, então a solução é fazer rollback da tarefa anterior e alterar a lógica que garante não duplicar os elementos (fazendo comparações equals com o campo `urlTitle` antes de insert into)
ANTES: FUNCIONAL PARA GERAR ID AUTO INCREMENT pois o django não tem essa funcionalidade para campos que NÃO SEJAM A CHAVE PRIMÁRIA ( id = models.AutoField(primary_key=True) ) <--- SÓ FUNCIONA PARA CHAVE PRIMÁRIA.
ESSA FOI A SOLUÇÃO ANTERIOR PARA GERAR OS ID's DE MANEIRA INCREMENTAL AUTOMÁTICAMENTE EM CASOS EM QUE A CHAVE PRIMÁRIA NÃO PODE SER A COLUNA ID:
global_last_id = JournalJsonArrayOfDOU.objects.all().aggregate(largest=models.Max('id'))['largest']
if global_last_id is None:
global_last_id = 1
dou_journals_toBe_insert = []
for obj in dou_journals_jsonArrayField_list:
journal_obj = JournalJsonArrayOfDOU(
id=global_last_id,
urlTitle=obj.urlTitle,
pubName=obj.pubName,
numberPage=obj.numberPage,
subTitulo=obj.subTitulo,
titulo=obj.titulo,
title=obj.title,
pubDate=obj.pubDate,
content=obj.content,
editionNumber=obj.editionNumber,
hierarchyLevelSize=obj.hierarchyLevelSize,
artType=obj.artType,
pubOrder=obj.pubOrder,
hierarchyStr=obj.hierarchyStr,
hierarchyList=obj.hierarchyList
)
dou_journals_toBe_insert.append(journal_obj)
global_last_id += 1
SOLUÇÃO AGORA: ROLLBACK PARA A TAREFA 15, PORÉM COM PEQUENAS MUDANÇAS NA LÓGICA QUE GARANTE DISTINCT DOS RECORDS.

djangoapp | django.db.utils.ProgrammingError: multiple primary keys for table "trigger_web_scraping_dou_api_journaljsonarrayofdou" are not allowed
Isso ocorre quando estavamos tentando alterar a coluna da chave primária pelo migrations, ao executar:
docker-compose run djangoapp python manage.py makemigrations
Será gerado o arquivo:
from django.db import migrations, models
class Migration(migrations.Migration):
dependencies = [
('trigger_web_scraping_dou_api', '0003_journaljsonarrayofdou_id'),
]
operations = [
migrations.AlterField(
model_name='journaljsonarrayofdou',
name='id', <---- NOVA CHAVE PRIMÁRIA DEPOIS DE MIGRAR
field=models.AutoField(primary_key=True, serialize=False),
),
migrations.AlterField(
model_name='journaljsonarrayofdou',
name='urlTitle',
field=models.CharField(max_length=255, unique=True), <---- CHAVE PRIMÁRIA ATUAL ANTES DE MIGRAR
),
]
AO QUE ESTÁ O PROBLEMA: A ordem das duas migrações gerada automáticamente é relevante!
Ao tentar aplicar as alterações para o primeiro:
migrations.AlterField(
model_name='journaljsonarrayofdou',
name='id', <---- NOVA CHAVE PRIMÁRIA DEPOIS DE MIGRAR
field=models.AutoField(primary_key=True, serialize=False),
),
Ocorre o erro, pois atualmente o campo `name='urlTitle'` é a chave primária.
SOLUÇÃO: Basta alterar a ordem para:
from django.db import migrations, models
class Migration(migrations.Migration):
dependencies = [
('trigger_web_scraping_dou_api', '0003_journaljsonarrayofdou_id'),
]
operations = [
migrations.AlterField(
model_name='journaljsonarrayofdou',
name='urlTitle',
field=models.CharField(max_length=255, unique=True), <---- CHAVE PRIMÁRIA ATUAL ANTES DE MIGRAR
),
migrations.AlterField(
model_name='journaljsonarrayofdou',
name='id', <---- NOVA CHAVE PRIMÁRIA DEPOIS DE MIGRAR
field=models.AutoField(primary_key=True, serialize=False),
),
]
Desta forma primeiro ele vai remover a chave primária do name='urlTitle' e depois aplicar no id.

Modificações em geral nas funções para não fazer duplicatas, pois a parte maior deste desenvolvimento foi feito na tarefa do primeiro endpoint, agora é só ir replicando nas assinaturas de outros endpoints o parâmetro `saveInDBFlagURLQueryString : bool`.
Já vai refletir a funcionalidade de salvar para todos, pois todos chamam a mesma função genérica que recebe a URL e faz a requisição, e nela passamos essa flag para salvar ou não. (Já garantindo DISTINCT).
