MeteorJS AutoForm.Hooks 没有更新文档

Question

我正在为 MeteorJS 使用很棒的 aldeed:autoform 包。我有一个自定义表单，可以让我创建数据库条目。

用户输入的表单字段之一是郊区，我正在使用 sergeyt:typeahead 包在用户输入时就此提出建议。

建议采用用户熟悉的格式（本质上是 "suburb, STATE, zipcode"）。我称之为 longsuburb。

然后我使用 AutoForm before hook 从用户 selected/entered longsuburb 值中分离出邮政编码 ("postcode") 值和 "suburb" 值。挂钩然后在提交文档之前将郊区和邮政编码值插入到文档中。

一切都很好。

现在我想创建一个编辑表单，用户可以在其中编辑详细信息（接下来我计划对两者使用相同的表单，但对我来说一次一步，因为我是新手） .

我已根据 AutoForm 示例设置了一个编辑表单模板并将类型设置为 "update"。

我可以成功编辑所有表单详细信息并将它们保存到集合中，除了我的 AutoForm 挂钩似乎根本没有被调用所以 "suburb" 和 "postcode" 值文档在提交时保持不变。

我尝试了几种不同的方法，但主要是在黑暗中拍摄，所以任何建议都很好。

这是编辑表单模板

    <template name="editBar">
  {{#autoForm collection="Bars" id="editBarsForm" template="bootstrap3-horizontal" label-class="col-sm-3" input-col-class="col-sm-9" type="update" doc=this}}
  <fieldset>
    <legend>Edit Bar</legend>
    {{> afQuickField name='bar_name' placeholder="Name of the Bar, Pub, Venue" class="form-control typeahead" }}
    {{> afQuickField name='image' class="form-control typeahead" }}
    {{> afQuickField name='url' placeholder="Venue's Website" class="form-control typeahead" }}
    {{> afQuickField name='longsuburb' placeholder="Suburb" class="form-control typeahead" autocomplete="off" spellcheck="off" data-source="getSuburbs"}}
    {{> afQuickField name='barType' options=bartypes class="selectpicker"}}
  </fieldset>
  <button type="submit" class="btn btn-primary submit">Submit</button>
    <a class="btn btn-danger delete" href="#">Delete post</a>
    <a class="btn btn-default cancel" href="#">Cancel</a>
  {{/autoForm}}
</template>

这是我在编辑表单 JS 文件中的内容

      Template.editBar.helpers({
  getSuburbs: function() {
    return AuPostcodes.find().fetch().map(function(it){ return it.longsuburb;     });
    console.log('it');
  },

  bartypes: function() {
    return [
      {label: "Select", value: ""},
      {label: "Bar", value: "bar"},
      {label: "Pub", value: "pub"}
    ];
  }

});



  Template.editBar.rendered = function(){
    Meteor.typeahead.inject();
  };


  //Split out suburb and postcide from form's longsuburb string and submit with doc to Bars collection.
  //"suburb" currently used for filtering.

  AutoForm.hooks({
      editBarsForm: {
          before:{
            insert: function(doc) {
              var suburbString = doc.longsuburb;
              var postcode = suburbString.substring(suburbString.lastIndexOf(",")+2,suburbString.length);
              var suburb = suburbString.substring(0,suburbString.indexOf(","));
              doc.postcode = postcode;
              doc.suburb = suburb;
              return doc; //autoFrom magic commence
              }
            }
          }
        });

Template.editBar.events({
  'click .delete': function(e) {
    e.preventDefault();

    if (confirm("Delete this bar?")) {
      var currentBarId = this._id;
      Bars.remove(currentBarId);
      Router.go('barsList');
    }
  },
  'click .cancel': function(e) {
    e.preventDefault();
    Router.go('barsList');
  }
});

添加模板和代码基本相同。正如我所说，一切都适用于创建记录。我还可以编辑名称、url、longsuburb 等并将它们保存到数据库中。只是文档插入不起作用。

Answer 1

看起来 doc.longsuburb 未定义。我以前有过类似的问题。您可以尝试从 this.currentDoc.longsuburb

获取 longsuburb 值

根据文档： https://github.com/aldeed/meteor-autoform#callbackshooks

The following properties and functions are available in all submission hooks when they are called. This does not include formToDoc, formToModifier, or docToForm.

...

this.currentDoc: The current document attached to the form (from doc attribute)

因此在您的 Edit Form JS 文件中，它应该如下所示：

//Split out suburb and postcide from form's longsuburb string and submit with doc to Bars collection.
//"suburb" currently used for filtering.

AutoForm.hooks({
  editBarsForm: {
    before:{
      update: function(doc) {
                var suburbString = this.currentDoc.longsuburb;
                var postcode = suburbString.substring(suburbString.lastIndexOf(",")+2,suburbString.length);
                var suburb = suburbString.substring(0,suburbString.indexOf(","));
                doc.$set.postcode = postcode;
                doc.$set.suburb = suburb;
                return doc; //autoFrom magic commence
              }
    }
  }
});

Answer 2

谢谢@Johnny。 almost 成功了，但在您的帮助下我得以解决。

基本上我有两个问题。正如您所指出的，我确实需要使用 doc.$set.key 来更新邮政编码和郊区值。但我还需要使用 AutoForm.getFieldValue 回调定义 suburbString 变量。

所以完整的解决方案如下所示：

  //Split out suburb and postcode from form's long suburb sting and submit with doc to Bars collection.
 //"suburb" currently used for filtering.

AutoForm.hooks({
  editBarsForm: {
      before:{
        update: function(doc) {
          var suburbString = AutoForm.getFieldValue("longsuburb");
          var postcode = suburbString.substring(suburbString.lastIndexOf(",")+2,suburbString.length);
          var suburb = suburbString.substring(0,suburbString.indexOf(","));
          doc.$set.postcode = postcode;
          doc.$set.suburb = suburb;
          return doc; //autoForm magic commence
          }
        }
    });
