Rails + React + Webpack加载图像

我正在使用Rails + Webpack将bundle.js文件编译到Rails资产管道中。我在/ app / assets / images中放置了一个名为“ main.png”的图像。如何在捆绑的React组件中访问此图像？

我正在使用shakacode在rails gem上的反应。https://github.com/shakacode/react_on_rails

然后，我尝试使用webpack处理成功完成的图像，并将该图像放置在bundle.js文件旁边。我仍然在图像上看到404。

我知道我已经接近了，只是将rails资产设置为publicPath错误。当前设置提供了一个不兼容rails的localhost：3000 / webpack / main.png。

这是我的webpack文件：

const webpack = require('webpack');
const path = require('path');

const devBuild = process.env.NODE_ENV !== 'production';
const nodeEnv = devBuild ? 'development' : 'production';

config = {
  entry: [
    'es5-shim/es5-shim',
    'es5-shim/es5-sham',
    'babel-polyfill',
    './app/Register.js',
  ],

  output: {
    filename: 'webpack-bundle.js',
    path: '../app/assets/webpack',
    publicPath: '/webpack/'
  },

  resolve: {
    extensions: ['', '.js', '.jsx'],
    alias: {
      react: path.resolve('./node_modules/react'),
      'react-dom': path.resolve('./node_modules/react-dom'),
    },
  },
  plugins: [
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: JSON.stringify(nodeEnv),
      },
    }),
  ],
  module: {
    loaders: [
      {
        test: require.resolve('react'),
        loader: 'imports?shim=es5-shim/es5-shim&sham=es5-shim/es5-sham',
      },
      {
        test: /\.jsx?$/, loader: 'babel-loader',
        exclude: /node_modules/,
      },
      {
        test: /\.(png|svg)$/i,
        loaders: [
        'file?hash=sha512&digest=hex&name=[hash].[ext]',
        'image-webpack?bypassOnDebug&interlaced=false'
        ]
      }
    ],
  },
};

module.exports = config;

if (devBuild) {
  console.log('Webpack dev build for Rails'); // eslint-disable-line no-console
  module.exports.devtool = 'eval-source-map';
} else {
  config.plugins.push(
    new webpack.optimize.DedupePlugin()
  );
  console.log('Webpack production build for Rails'); // eslint-disable-line no-console
}
