Meteor Autoform Bootstrap Modals

Allows to show autoforms in Bootstrap modals.

Difference between yogiben:autoform-modals

The guys from yogiben have created a great package thanks for this. But it has some issues that provoked me to develop this package. The main problem is that yogiben package uses static Boostrap Modal and session variables in order to setup Autoform settings. For the autoform with simple fields it can work good enough but if you have autoform that uses complex autoform fields - the autoform starts to show wrong values in complex fields after saving and opening Modal again. I call afField as Complex if it has .created, .rendered callbacks defined in its template. For example yogiben:Autoform Tags or VeliovGroup:Autoform Files.

The main idea of this package is to use dynamic way of Modal template generation using Blaze.renderWithData. It allows to get rid of using sessions and gives some sufficient advantages.

Features

• Package uses dynamic way of Modal template generation / destruction using PeppeL-G:Bootstrap-3-Modal
• Ability to pass subscriptions and have Template Level Subscription for Modal template
• Ability to remove documents by using aldeed:meteor-delete-button and get access to all callbacks that are provided by this package

Setup

1. meteor add peppelg:bootstrap-3-modal link
2. meteor add aldeed:delete-button link
3. meteor add aposidelov:autoform-bootstrap-modal
4. Use afModalShow template to create a link that will trigger the modal

How to use

Insert Example

{{#afModalShow formId="addProduct" collection="products" type="insert" class="btn btn-primary"}}
	Add
{{/afModalShow}}

Update Example

{{#afModalShow formId="editProduct" collection="products" type="update" doc=this._id class="btn btn-primary"}}
	Update
{{/afModalShow}}

Update with Template Level Subscription Example

...
Template.ProductItem.helpers({
    productSubscriptions: (instance) => {
        var productId = this._id;
        return (instance) => {
            instance.subscribe('products.one', productId);            
        }
    }
});

<template name="ProductItem">
  {{#afModalShow formId="editProduct" collection="products" type="update" doc=this._id subscriptions=productSubscriptions class="btn btn-primary"}}
  	Update
  {{/afModalShow}}
</template>

Autoform Callbacks/Hooks Example

It works the same way as with normal autoform.

...
AutoForm.addHooks('editProduct', {  
  onSuccess: function() {              
    // your code
  }  
});

Read more in the autoform callbacks/hooks section.

Remove Example

{{#afModalShow collection="products" type="remove" doc=this._id class="btn btn-primary" title="Confirm modal" prompt="Are you sure?" buttonContent="Submit"}}
	Delete
{{/afModalShow}}

Remove with callbacks Example

...
Template.ProductItem.helpers({
  myBeforeRemove: (collection, id, quickRemoveButton) => {
    return (collection, id, quickRemoveButton) => {      
      var doc = collection.findOne(id);
      if (confirm('Really delete "' + doc.name + '"?')) {
        quickRemoveButton.remove();
      }
    }
  },
  myOnError: (error) => {
    return (error) => { alert("BOO!"); console.log(error); };
  },
  myOnSuccess: (result) => {
    return (result) => {
      alert("YAY!"); console.log(result);
    };
  }
});

<template name="ProductItem">
  {{#afModalShow collection="products" type="remove" doc=this._id class="btn btn-primary" title="Confirm modal" prompt="Are you sure?" buttonContent="Confirm" closeButtonContent="Close" beforeRemove=myBeforeRemove afterRemove=myOnSuccess errorRemove=myOnError}}
  	Delete
  {{/afModalShow}}
</template>
