我一直在研究这个问题,但无法从任何帖子中找出解决方案。我希望有人可以帮我弄清楚这个问题,以便将我的应用程序部署到Heroku。
我尝试设置环境变量并在两个模型index.js
和config.json
中都包括方言。我在配置中声明了它。
config.json
:
{
"development": {
"username": "root",
"password": null,
"database": "ragnar_db",
"host": "127.0.0.1",
"dialect": "mysql"
},
"test": {
"username": "root",
"password": null,
"database": "ragnar_db",
"host": "127.0.0.1",
"dialect": "mysql"
},
"production": {
"use_env_variable": "JAWSDB_URL",
"dialect": "mysql"
}
}
modles/index.js
:
"use strict";
var fs = require("fs");
var path = require("path");
var Sequelize = require("sequelize");
var basename = path.basename(module.filename);
var env = process.env.NODE_ENV || "development";
var config = require(__dirname + "/../config/config.json")[env];
var db = {};
if (config.use_env_variable) {
var sequelize = new Sequelize(process.env[config.use_env_variable]);
console.log(process.env);
} else {
var sequelize = new Sequelize(
config.database,
config.username,
config.password,
config
);
}
fs.readdirSync(__dirname)
.filter(function (file) {
return (
file.indexOf(".") !== 0 && file !== basename && file.slice(-3) === ".js"
);
})
.forEach(function (file) {
var model = sequelize.import(path.join(__dirname, file));
db[model.name] = model;
});
Object.keys(db).forEach(function (modelName) {
if (db[modelName].associate) {
db[modelName].associate(db);
}
});
db.sequelize = sequelize;
db.Sequelize = Sequelize;
module.exports = db;
答案 0 :(得分:0)
答案是通过这种方式为较旧的Sequelize版本提供代码。
if (config.use_env_variable) {
var sequelize = new Sequelize(process.env[config.use_env_variable]);
console.log(process.env);
} else {
var sequelize = new Sequelize(
config.database,
config.username,
config.password,
{
host: "host_name",
dialect: "Your_dialect"
});
}
另一个答案是重新初始化Sequelize-cli并运行用于配置数据库的命令。然后运行Sequelize -init,如果您通过终端进行了所有设置,则init将为环境变量存储JAWSDB_URL并将其设置在节点和heroku环境中。否则,它将要求您将JAWSDB_URL粘贴到终端查询器中。这是对旧版本的更改,以允许Sequelize比以前更好地隐藏数据库信息,但是如果您使用的是具有旧代码的最新版本,则必须同时在conf.json / config.js和models / index.js中。
