Question

I am using meteor and Aldeed's autoform to populate my database. The basic functionality I want to achieve is this:

Have principal form linked to a collection as normal.
In the principal form, have a button add secondary which dynamically adds forms linked to a different collection.
The second form has a remove button which removes it.

I followed the technique outlined here and put together the following code :

        <template name="PricipalForm">

        {{#autoForm collection="principal" id="Principalform" type="insert" }}
            <fieldset>
                <legend>Principal form</legend>
                {{> afQuickField name='field1'}}
                {{> afQuickField name='field2'}}
                <button id='add-inputs' type="button">
                        Add Proposal
                 </button>

                 {{#each inputs}}
                        {{> AddSecond}}
                 {{/each}}

            </fieldset>
            <button type="submit" class="btn btn-primary">Insert</button>
        {{/autoForm}}
    </template>

./Templates/PrincipalForm.html

Template.PrincipalForm.onCreated(function() {
   Session.set('props', []);
 });


  Template.Create.events({
     'click #add-inputs': function () {
      var inputs = Session.get('inputs');
      var uniqid = Math.floor(Math.random() * 100000); /
      inputs.push({uniqid: uniqid});
      Session.set('inputs', inputs);
      }
  });

  Template.Create.helpers({
      inputs: function(){
         return Session.get('inputs');
       }
   });

 <template name ="SecondaryFrom">

     {{#autoForm collection="secondary" id="secondaryForm" type="insert" }}
      <fieldset>
       <legend> One instance of secondary form </legend>
          {{> afQuickField name='fieldA'  }}
          {{> afQuickField name='fieldB'}}
      </fieldset>
      <button class='remove-inputs' uniqid="{{uniqid}}" type="button">Remove</button>
{{/autoForm}}

</template>


  ./Templates/SecondaryForm.html

  //////////////////////////////////////////

  Template.AddProposal.events({
     'click .remove-inputs': function(event) {
         var uniqid = $(event.currentTarget).attr('uniqid');
         var props = Session.get('inputs');
         props = _.filter(props, function(x) { return x.uniqid != uniqid; });
         Session.set('inputs', inputs);
          },

   });


  ./Templates/SecondaryForm.js

This code works fine, there is only one bug that I do not understand:

I first add 3 secondary forms and put the values abc , efg , hij in fieldA of these three forms respectively.
Then I remove the second secondary form with efg and what I get is that the remaining ones are abc and efg !!
where it gets more weird is that when I check the uniqid of the removed form is the one expected (and corresponding to the previous efg).

So it seems that when I remove the form dynamically, the values that I type in persist somehow.

Can anyone please help out:

What goes wrong in what I am doing, how could I fix it?
Is there perhaps a better way to do what I am trying to do?

I also tried to check the answer here , but the links provided were broken.

Thanks

我通过完全使用aldeed:autoform和aldeed:collection2来解决此问题，以便生成表单，而不是手动插入辅助模板。

这可以通过像往常一样创建两个想要的模式，然后将二级模式作为一个数组放到主模式上来实现。

然后问题是在autoform中使用{{> afArrayfield}}来实现问题中概述的预期结果。

代码看起来像这样：

//Schema definition:  
Primary = new Mongo.collection('Primary');
secondary = new SimpleSchema({
   /* ... */
 });
 primary = new SimpleSchema({
   /*...*/
  secondaries:{
   type:[secondary]
  }
 });

Primary.attachSchema(primary);

//On the HTML form:
{{autoform collection="Primary" id= "form_example" type="insert"}}
<fieldset>
   /* any fields*/
   {{afArrayField name = 'secondaries'}}
</fieldset>
{{/autoform}}
