MongoDb - Projeto Final

Autor: Paulo Roberto da Silva Data Date.now() //em timestamp

Para qual sistema você usaria o MogoDB (diferente desse)?

O MongoDb é perfeito pra sistemas que possuem grande processamento de dados não-relacionados entre si. Banco de dados de supermercados onde serão guardadas as notas fiscais ou os preços e dados dos produtos seria uma boa utilização.

Qual a modelagem da sua coleção de users?

user : {
  name: { type : String }
  ,bio: { type : String }
  ,date_register: { type : Date }
  ,avatar_path: { type : String }
  ,auth: {
    username: { type : String }
    ,email: { type : String }
    ,password: { type : String }
    ,last-access: { type : Date }
    ,online: { type: Boolean }
    ,disabled: { type: Boolean }
    ,hash-token: { type : String }
  }
}

Qual a modelagem da sua coleção de projects?

  ,date_dream: { type : Date }
  ,date_end: { type : Date }

          { date_realocate: { type: Date } }
        ]
      }
      ,activities:
        [
          id_activity : { type : ObjectID}
        ]
    ]
  ,members:
    [
      {
        id_user: { type : ObjectID }
        ,type_member : { type : String }
        ,notify: { type : Boolean }
      }
    ]
}

Qual a modelagem da sua coleção retirada de projects?

Foi escolhida a parte de atividades para ser criada uma collection unica por ela ser grande e como um projeto pode ter muitas metas e cada meta muitas atividades, isso pode tornar o documento a ser salvo grande demais para o limite de 16 MB que o MongoDB suporta.

activity: {
  name: { type : String },
  ,description: { type : String }
  ,date_begin: { type : Date }
  ,date_dream: { type : Date }

  ,realocate: { type: Boolean }
  ,expired: { type: Boolean }
  ,members_activity :
    [
      {
        id_user : { type : ObjectID }
        ,type_member : { type : String }
        ,notify: { type : Boolean }

        ,member:{

          ,notify: { type : Boolean }
        }

        ,file: {
          path: { type : String }
          ,weight: { type : Number }
          ,name: { type : String }
        }

Gerenciamento de usuários

1. Crie um usuário com permissões APENAS de Leitura.

paulo-sti-ni-1401(mongod-3.2.3) be-mean-mongo> var user = { createUser: "Paulo",
...   pwd: "123",
...   roles: [
...     { role: "read", db: "be-mean-mongo" }
...   ]
... }
paulo-sti-ni-1401(mongod-3.2.3) be-mean-mongo> db.createUser(user);
Successfully added user: {
  "createUser": "Paulo",
  "roles": [
    {
      "role": "read",
      "db": "be-mean-mongo"
    }
  ]
}

2. Crie um usuário com permissões de Escrita e Leitura.

paulo-sti-ni-1401(mongod-3.2.3) be-mean-mongo> var user = { createUser: "PauloLeituraEscrita",
...   pwd: "123",
...   roles: [
...     { role: "readWrite", db: "be-mean-mongo" }

paulo-sti-ni-1401(mongod-3.2.3) be-mean-mongo> db.createUser(user);
Successfully added user: {
  "createUser": "PauloLeituraEscrita",
  "roles": [
    {
      "role": "readWrite",
      "db": "be-mean-mongo"
    }
  ]
}

3. Adicionar o papel grantRolesToUser e revokeRole para o usuário com Escrita e Leitura.

paulo-sti-ni-1401(mongod-3.2.3) be-mean-mongo> db.runCommand({
...   createRole: "grantRolesToUser",
...   privileges : [
...     { resource : { db : "be-mean-mongo", collection : "" }, actions : [ "grantRolesToUser" ]}
...   ],
...   roles : []
...  })
{
  "ok": 1
}
paulo-sti-ni-1401(mongod-3.2.3) be-mean-mongo> db.runCommand({
...   createRole: "revokeRole",
...   privileges : [
...     { resource : { db : "be-mean-mongo", collection : "" }, actions : [ "revokeRole" ]}

... });
{
  "ok": 1
}
paulo-sti-ni-1401(mongod-3.2.3) be-mean-mongo> db.runCommand({ usersInfo: { user: "PauloLeituraEscrita", db: "be-mean-mongo" }})
{
  "users": [
    {
      "_id": "be-mean-mongo.PauloLeituraEscrita",

        {
          "role": "readWrite",
          "db": "be-mean-mongo"
        }
      ]
    }
  ],
  "ok": 1
}

4. Remover o papel grantRolesToUser para o usuário com Escrita e Leitura.

paulo-sti-ni-1401(mongod-3.2.3) be-mean-mongo> db.runCommand( { revokeRolesFromUser: "PauloLeituraEscrita",
...   roles: [
...           { role: "revokeRole", db: "be-mean-mongo" },

  "users": [
    {
      "_id": "be-mean-mongo.PauloLeituraEscrita",
      "user": "PauloLeituraEscrita",
      "db": "be-mean-mongo",
      "roles": [
        {
          "role": "grantRolesToUser",

          "role": "readWrite",
          "db": "be-mean-mongo"
        }
      ]
    }
  ],
  "ok": 1
}

5. Listar todos os usuários com seus papéis e ações.
