dva model 如何使用takeLatest高阶函数？

[behind2]

const model = {
  namespace: 'article',
  state: {
    logger: {
      sortedInfo: {
        order: 'descend',
        columnKey: 'create_time',
      },
    },
  },
  subscriptions: {
    url( {dispatch, history} ) {
      history.listen(( {pathname} ) => {
        const match = pathToRegexp('/article/:cmsid').exec(pathname)
        if (match && match[1]) {
          let cmsid = match[1]
          dispatch({type: 'loadCmsid2Docid', payload: {cmsid}})// 多次调用
          // dispatch({type: 'loadArticleRdmDebugInfo', payload: {cmsid}})// 多次调用
        }
      });
    },
  },
  effects: {
    *loadCmsid2Docid({payload}, {call, put, take, takeLatest}) {
      const docid = yield call(loadCmsid2Docid, payload)

      console.log('startstartstartstartstart')
      let tt1 = yield takeLatest( 'loadCmsid2Docid', model.effects['article/fetchUser'] )
      console.log('tt1tt1tt1tt1tt1tt1tt1', tt1)
      console.log('endendendendendendendend')

    },

    *fetchUser(action) {
      debugger
    },

  },
  reducers: {

  },
}

export default model

请问这段代码，为什么无法使用takeLatest这种高阶函数呢？而且fetchUser函数没有被调用呢，请问哪位老司机可以帮忙指点下？

takeLatest should be used in this way: https://github.com/dvajs/dva/blob/master/docs/API.md#effects
example: https://github.com/nihgwu/react-native-dva-starter/blob/master/app/models/router.js#L24-L40

Woooo! Very nice! The doc I readed is vague. 3Q
