Question

我有一个{{link-to}}，它将ID传递给detailhes.js路由。此路由findRecord我的模型传递{{link-to}} ID。有效负载加载所有数据，但是当页面完成加载时，它会出现错误。我没有找到“钥匙”，我没有pokemon.detalhes控制器。 Ember 2.18.1

Error: Assertion Failed: The key provided to set must be a string, you passed (generated pokemon.detalhes controller).

我的代码： adapter.js

import DS from 'ember-data';
import { computed } from '@ember/object';

export default DS.RESTAdapter.extend({

    host: 'http://127.0.0.1:8000',
    namespace: 'api/v2',
    headers: computed(function () {
        return {
            'accept': 'application/json'
        };
    }),

    pathForType(type) {
        return type;
    },
/*
    query(store, b, query) {
        store.serializerFor('pokemon').set('pageSize', query.limit);
        const url = `${this.get('host')}/${this.get('namespace')}/pokemon`;
        console.log(url);
        return this.ajax(url, 'GET', {data: query});
    },
*/
    updateRecord(store, type, snapshot) {
        const data = snapshot.record.serialize();
        const headers = Object.assign({}, this.get('headers'), { "pokemon-edit": true });
        const url = this.buildURL(type.modelName, snapshot.id, snapshot, 'updateRecord');
        return this.ajax(url, 'PUT', { headers, data });
    }
});

serializer.js

import DS from 'ember-data';

export default DS.RESTSerializer.extend({

normalizeResponse(store, primaryModelClass, payload) {

          count: payload.count,
          previous: payload.previous,

                type: 'pokemon',
                attributes: item

router.js

import EmberRouter from '@ember/routing/router';
import config from './config/environment';

const Router = EmberRouter.extend({
  location: config.locationType,
  rootURL: config.rootURL
});

Router.map(function() {
  this.route('pokemon', function() {
    this.route('edit');
    this.route('edit', { path: 'edit/:id' });
    this.route('detalhes');
    this.route('detalhes', { path: 'detalhes/:id' })
  });
});

export default Router;

Answer 1

您没有控制器“pokemon.detalhes”，但您正在尝试转换到路线“pokemon.detalhes”，以便Ember自动为您创建该控制器。但正如我从你的代码中看到的那样，你有路径“pokemon.details”。所以试着用这个：

<td>{{#link-to "pokemon.details" poke.id}}<p class="btn btn-success">Details</p>{{/link-to}}</td>

如果这不正确，请与我们分享您的router.js的代码，以便我们获得更好的洞察力。

Answer 2

我发现了问题，这是setupController。
我改写了detalhes路由器并且工作!!

路线/小宠物/ detalhes.js

export default Route.extend({
    model(params) {
        return this.store.findRecord('pokemon', params.id)
    }
});
