[英]How to get relationship model in Keystone.js
因此,我嘗試從“ TestGenerator”模型的“句子”模型中獲取“代詞”模型。 我有身份證,但沒有模特。
TestGenerator模型
var TestGenerator = new keystone.List('TestGenerator', {
map: { name: 'title' },
autokey: { path: 'slug', from: 'title', unique: true }
});
TestGenerator.add({
title: { type: String, required: true },
sentences: { type: Types.Relationship, ref: 'Sentence', many: true },
});
TestGenerator.register();
var Sentence = new keystone.List('Sentence', {
map: { name: 'title' },
autokey: { path: 'slug', from: 'title', unique: true }
});
句子模型
Sentence.add({
title: { type: String, required: true },
pronouns: { type: Types.Relationship, ref: 'Pronoun', many: true },
verbs: { type: Types.Relationship, ref: 'Verb', many: true },
});
Sentence.relationship({ ref: 'TestGenerator', path: 'sentences' });
Sentence.register();
Ponoun模型
var Pronoun = new keystone.List('Pronoun', {
map: { name: 'english' },
autokey: { path: 'slug', from: 'english', unique: true },
});
Pronoun.add({
english: { type: String },
russian: { type: String }
});
Pronoun.relationship({ ref: 'Sentence', path: 'pronouns' });
Pronoun.register();
還有我的控制器
view.on('init', function (next) {
var q = keystone.list('TestGenerator').model.findOne({
slug: locals.filters.test_genetation,
}).populate('sentences');
q.exec(function (err, result) {
locals.testGenerator = result;
locals.current_sentence = result.sentences[0];
locals.data.englishSentence = locals.current_sentence.pronouns;
console.log(locals.data.englishSentence);
next(err);
});
});
和“ locals.data.englishSentence”返回
["5739bd696ef7d78d16e9e0e5","573ac7645e3d7d7210f1c4be"]
那么我該如何解決呢? 不明白
這與貓鼬有關,實際上與Keystone不相關。 貓鼬不提供大量人口,您需要一個單獨的插件,例如mongoose-deep-populate
您是否嘗試過在populate()
調用中明確包含pronouns
?
var q = keystone.list('TestGenerator').model.findOne({
slug: locals.filters.test_genetation,
})
.populate('sentences sentences.pronouns')
.exec(function (err, result) {
...
});
