ng-admin

Plug me to your RESTFul API to get a complete administration tool (CRUD, multi-model relationships, dashboard, complex form widgets) in no time!

Check out the online demo (source), and the launch post.

Installation

Retrieve the module from bower:

bower install ng-admin --save

Include the ng-admin CSS, and the ng-admin JS (after the angular.js JS):

<link rel="stylesheet" href="/path/to/bower_components/ng-admin/build/ng-admin.min.css">
<script src="/path/to/bower_components/angular/angular.min.js" type="text/javascript"></script>
<script src="/path/to/bower_components/ng-admin/build/ng-admin.min.js" type="text/javascript"></script>

Make your application depend on it:

var app = angular.module('myApp', ['ng-admin']);

Configure ng-admin:

app.config(function (NgAdminConfigurationProvider, Application, Entity, Field, Reference, ReferencedList, ReferenceMany) {
    // set the main API endpoint for this admin
    var app = new Application('My backend')
        .baseApiUrl('http://localhost:3000/');

    // define an entity mapped by the http://localhost:3000/posts endpoint
    var post = app.addEntity('posts');

    // set the list of fields to map in each post view
    post.dashboardView().addField(/* see example below */);
    post.listView().addField(/* see example below */);
    post.creationView().addField(/* see example below */);
    post.editionView().addField(/* see example below */);
    
    NgAdminConfigurationProvider.configure(app);
});

Your application should use a ui-view:

<div ui-view></div>

Example Configuration

We chose to define the entities & views directly in JavaScript to allow greater freedom in the configuration.

Here is a full example for a backend that will let you create, update, and delete some posts (posts entity). Those posts can be tagged (tags entity) and commented (comments entity).

var app = angular.module('myApp', ['ng-admin']);

app.config(function (NgAdminConfigurationProvider, Application, Entity, Field, Reference, ReferencedList, ReferenceMany) {

    var app = new Application('ng-admin backend demo') // application main title
        .baseApiUrl('http://localhost:3000/'); // main API endpoint

    // define all entities at the top to allow references between them
    var post = new Entity('posts'); // the API endpoint for posts will be http://localhost:3000/posts/:id
    var comment = new Entity('comments')
        .identifier(new Field('id')); // you can optionally customize the identifier used in the api ('id' by default)
    var tag = new Entity('tags')
        .readOnly(); // a readOnly entity has disabled creation, edition, and deletion views

    // set the application entities
    app
        .addEntity(post)
        .addEntity(tag)
        .addEntity(comment);

    // customize entities and views

    post.dashboardView()
        .title('Recent posts')
        .order(1) // display the post panel first in the dashboard
        .limit(5) // limit the panel to the 5 latest posts
        .pagination(pagination) // use the custom pagination function to format the API request correctly
        .addField(new Field('title').isDetailLink(true).map(truncate));

    post.listView()
        .title('All posts') // default title is "[Entity_name] list"
        .pagination(pagination)
        .addField(new Field('id').label('ID'))
        .addField(new Field('title')) // the default list field type is "string", and displays as a string
        .addField(new ReferenceMany('tags') // a Reference is a particular type of field that references another entity
            .targetEntity(tag) // the tag entity is defined later in this file
            .targetField(new Field('name')) // the field to be displayed in this list
        )
        .listActions(['show', 'edit', 'delete']);

    post.creationView()
        .title('Add a new post') // default title is "Create a post"
        .addField(new Field('title')) // the default edit field type is "string", and displays as a text input
        .addField(new Field('body').type('wysiwyg')) // overriding the type allows rich text editing for the body

    post.editionView()
        .title('Edit post "{{ entry.values.title }}"') // title() accepts a template string, which has access to the entry
        .addField(new Field('title'))
        .addField(new Field('body').type('wysiwyg'))
        .addField(new ReferenceMany('tags')
            .targetEntity(tag)
            .targetField(new Field('name'))
        )
        .addField(new ReferencedList('comments')
            .targetEntity(comment)
            .targetReferenceField('post_id')
            .targetFields([
                new Field('id'),
                new Field('body').label('Comment')
            ])
        );

    post.showView() // a showView displays one entry in full page - allows to display more data than in a a list
        .addField(new Field('id'))
        .addField(new Field('title'))
        .addField(new Field('body').type('wysiwyg'))
        .addField(new ReferenceMany('tags') 
            .targetEntity(tag) 
            .targetField(new Field('name')) 
        );

    comment.dashboardView()
        .title('Last comments')
        .order(2) // display the comment panel second in the dashboard
        .limit(5)
        .pagination(pagination)
        .addField(new Field('id'))

            .template(function () { // template() can take a function or a string
                return '<custom-post-link></custom-post-link>'; // you can use custom directives, too
            })
        );

                month = now.getMonth() + 1,
                day = now.getDate();
            month = month < 10 ? '0' + month : month;
            day = day < 10 ? '0' + day : day;
            return {
                created_at: [year, month, day].join('-') // ?created_at=... will be appended to the API call
            };
        });

    tag.showView()
        .addField(new Field('name'))
        .addField(new Field('published').type('boolean'));

    NgAdminConfigurationProvider.configure(app);
});

Entity Configuration

Each entity maps to a different API endpoint. The name of the entity, defines the endpoint:

// set the main API endpoint for this admin
var app = new Application('My backend')
    .baseApiUrl('http://localhost:3000/');

// define an entity mapped by the http://localhost:3000/posts endpoint
var post = new Entity('posts');

label() Defines the name of the entity, as displayed on screen

  var comment = new Entity('comments').label('Discussions');

readOnly() A read-only entity doesn't allow access to the mutation views (editionView, creationView, deletionView). In addition, all links to the editionView are replaced by links to the showView.
```
  var tag = new Entity('tags').readOnly();
```

View Configuration

View Types

Each entity has 6 views that you can customize:

listView:
creationView
editionView
showView (unused by default)
deletionView
dashboardView: this is a special view to define a panel in the dashboard (the ng-admin homepage) for an entity.

General View Settings

These settings are available on all views.

addField(Field) Add a column to a list, or a form control to a form, mapped by a property in the API endpoint result.
title(String) The title of the view. ng-admin sees it as a template, and compiles it with the view scope. That means you can customize the title of a view using details from the current entry.
```
  editView.title('Edit item "{{ entry.values.title }}"');
```
description(String) A text displayed below the title.
actions(String|Array) Customize the list of actions for this view. You can pass a list of button names among 'back', 'list', 'show', create', 'edit', 'delete':
```
  editView.actions(['show', 'list', 'delete']);
```

Alternately, if you pass a string, it is compiled just like an Angular template, with access to the current entry in the scope. This allows to easily add custom actions, or customize the buttons appearance:

var template = '<show-button entry="entry" entity="entity" size="sm"></show-button>' +
               '<delete-button entry="entry" entity="entity" size="sm"></delete-button>' +
               '<my-custom-directive entry="entry"></my-custom-directive>' +
               '<back-button></back-button>';
editView.actions(template);

extraParams(function|Object) Add extras params to each API request.
headers(function|Object) Add headers to each API request.
interceptor(function) Used to transform data from the API into an array of element.
disable() Disable this view. Useful e.g. to hide the panel for one entity in the dashboard, or to disable views that modify data and only let the listView enabled

dashboardView Settings

order(Number) Define the order of the Dashboard panel for this entity in the dashboard

listView Settings

perPage(Number) Define the number of element displayed in a page

pagination(function) Define the parameters used to paginate the API:

  listView.pagination(function(page, maxPerPage) {
      return {
          begin: (page - 1) * maxPerPage, 
          end: page * maxPerPage
      };
  });

filterQuery(function) Define the parameters used to query the API:

  listView.filterQuery(function(searchQuery) {
      return { q: searchQuery };
  });

filterQuery(function) Define parameters used to query the API. See below.
infinitePagination(boolean) Enable or disable lazy loading.

totalItems(function) Define a function that return the total of items:

  listView.totalItems(function(response) {
      return response.headers('X-Total-Count');
  });

sortParams(function) Define parameters used to sort the API:

  listView.sortParams(function(field, dir) {
      return {
          params: { _sort: field, _sortDir: dir },
          headers: {}
      };
  });

addQuickFilter(function) Add button to set several filter parameters at once.

  listView.addQuickFilter('Published', function () {
      return {
          published: true
      };
  });

Quickfilters can be customised with filterParams:

  listView.filterParams(function (param) {
     if (param) {
         param.abc = '';
     }
     return param;
  });

listActions(String|Array) Add an action column with action buttons on each line. You can pass a list of button names among 'show', 'edit', and 'delete'.
```
  listView.listActions(['edit', 'delete']);
```

Alternately, if you pass a string, it is compiled just like an Angular template, with access to the current entry in the scope. This allows to add custom actions on each line:

var template = '<show-button entry="entry" entity="entity" size="xs"></show-button>'+
               '<my-custom-directive entry="entry"></my-custom-directive>';
listView.listActions(template);

Fields

A field is the representation of a property of an entity.

Field Classes

Field: simple field (possible types: number, string, text, boolean, wysiwyg, email, date, choice, choices, template)
Reference: one-to-many association with another entity
ReferencedList: many-to-one association
ReferenceMany: many-to-many association

General Field Settings

type(string ['number'|'string'|'text'|'boolean'|'wysiwyg'|'email'|'date'|'choice'|'choices'|'template']) Define the field type. Default type is 'string', so you can omit it.
label(string label) Define the label of the field. Defaults to the uppercased field name.
displayed(boolean) Should the field be displayed in the view ? Useful when we need to retrieve data for custom field
editable(boolean) Define if the field is editable in the edition form. Usefult to display a field without allowing edition (e.g for creation date).
order(number|null) Define the position of the field in the view.
format(string ['yyyy-MM-dd' by default]) Define the format for date type.
isDetailLink(boolean) Tell if the value is a link in the list view. Default to true for the identifier field, false otherwise. The link points to the edition view, except for read-only entities, where it points to the show view.
choices([{value: '', label: ''}, ...]) Define array of choices for choice` type. A choice has both a value and a label.

map(function) Define a custom function to transform the value. It receive the value and the corresponding entry. Works in list, edit views and references.

  myView.addField(new Field('characters')
      .map(function truncate(value, entry) {
          return value + '(' + entry.values.subValue + ')';
      })
  );

Multiple map can be defined for a field:

  myView.addField(new Field('comment')
      .map(stripTags)
      .map(truncate)
  );

validation(object) Tell how to validate the view

required: boolean
validator: function(value){}
min-length: number
max-length: number

defaultValue(*) Define the default value of the field in the creation form.
template(*) Define the template to be displayed (can be a string or a function).

Reusable Directives

The template field type allows you to use any HTML tag, including custom directives. ng-admin provides ready-to-use directives to easily add interactions to your admin views:

<show-button>
<edit-button>
<delete-button>

Buttons linking to the related view for the given entry.

entity.listView()
   //
   .addField(new Field('actions').type('template').template('<show-button entry="entry" entity="view.entity" size="xs"></show-button>'));

<create-button>
<list-button>

A button linking to the related view for the given entity.

`listView.listActions()`

The listActions() method available on the listView is a shortcut to adding a template field with one of the directives listed above. In practice, calling:

listView.listActions(['edit', 'delete']);

Is equivalent to:

var template = '<edit-button entry="entry" entity="view.entity" size="xs">' +
               '</edit-button>' +
               '<delete-button entry="entry" entity="view.entity" size="xs">' +
               '</delete-button>';
listView.addField(new Field('actions').type('template').template(template));

Relationships

Reference

The Reference type also defines label, order, map, list & validation options like the Field type.

targetEntity(Entity) Define the referenced entity.

targetLabel(string) Define the target field name used to retrieve the label of the referenced element.

  myView.addField(new Reference('post_id')
      .label('Post title')
      .map(truncate) // Allows to truncate values in the select
      .targetEntity(post) // Select a target Entity
      .targetField(new Field('title')) // Select a label Field
  );

ReferencedList

The ReferencedList type also defines label, order, map, list & validation options like the Field type.

targetEntity(Entity) Define the referenced entity.
targetReferenceField(string) Define the field name used to link the referenced entity.

targetFields(Array(Field)) Define an array of fields that will be displayed in the list of the form.

  myEditView.addField(new ReferencedList('comments') // Define a N-1 relationship with the comment entity
      .label('Comments')
      .targetEntity(comment) // Target the comment Entity
      .targetReferenceField('post_id') // Each comment with post_id = post.id (the identifier) will be displayed
      .targetFields([ // Display comment field to display
          new Field('id').label('ID'),
          new Field('body').label('Comment')
      ])
      )
  );

ReferenceMany

The ReferenceMany type also defines label, order, map & validation options like the Field type.

targetEntity(Entity) Define the referenced entity.

targetField(Field) Define the field name used to link the referenced entity.

  myView.addField(new ReferenceMany('tags')
     .label('Tags')
     .isEditLink(false)
     .targetEntity(tag) // Targeted entity
     .targetField(new Field('name')) // Label Field to display in the list
  )
