Question

我正在使用normalizr来规范化响应。

我的问题是我不知道如何管理规范化的响应。

{
  result:[]
  entities: {
    words: {
      //...
      1: {
       definitions: [1, 2, 3]
      }
      // other word objects...      
    },
    definitions: {

      1: 'blah blah'
      2: 'blah blah'
      3: 'blah blah'
      // definition objects
    }
  }
}

我想将这些词语传递给带有定义的反应组件。如何检索具有嵌套定义的单词并将其呈现给我的组件。

假设您的州看起来像这样

entities: {
    words: {
        //...
        1: {
            id:1,
            text:"Word",
            definitions: [1, 2, 3]
        },
        // other word objects...
    },
    definitions: {
        1: {id:1, text:'blah blah'},
        2: {id:2, text:'blah blah'},
        3: {id:3, text:'blah blah'},
        // definition objects
    }
},
wordsById : [1,4,7,8,22]

然后...... WordList可能看起来像这样。从状态切片ID，以呈现列表

const WordList = ({ids}) => <div>{ids.map(id => <Word id={id} key={id}/>)}</div>;

export default connect(state =>({ ids:state.wordsById }))(WordList);

和Word组件：从道具中通过id获取特定单词，通过地图计算定义列表

const Word = ({word, definitions}) =>(
    <div className="word-block">
        <span>{word.text}</span>
        <DefinitionsList definitions={definitions}/>
    </div>
)

const mapStateToProps = (state, props) =>{
    const word = state.entities.words[props.id];
    const { definitions:ids } = word
    return {
        word,
        definitions:ids.map(id => state.entities.definitions[id])
    };
}

export default connect(mapStateToProps, actions)(Word);

和DefinitionsList

const DefinitionsList = ({definitions})=> (
    <div className="definitions">
        {definitions.map(def =><div key={def.id}>{def.text}</div>)}
    </div>
);

功能组件仅用于简短。

处理标准化响应的最佳方法是什么？
