Upgrading 1.x to 2.0 - Sage/argos-sdk GitHub Wiki

#Upgrading 1.2 to 2.0 With the release of SLX Mobile 2.0 there have been many major changes in how the application works. This was done not only to align with SLX Web but to also bring faster performance, newer features and a more customize-able environment. These changes include:

  • AMD script loading;
  • Removed the Ext framework and replaced it with Dojo 1.7.1;
  • Minor folder restructuring;
  • Properties and Functions renamed to be more descriptive; and
  • Additional properties and functions to enhance customizing.

##Steps to Convert

  1. Change all modules (files) to use AMD loading.
  2. Change all Ext calls to Dojo equivalents.
  3. Verify that all modules names are fixed to reflect the new folder structure.
  4. Verify that any property name changes do not effect your views or customization's.
  5. Verify that the changed function names/removal do not effect your views or customization's.
  6. Consider the newly added properties and methods to enhance existing customization's.

###AMD Script Loading AMD stands for Asynchronous Module Definition which means that instead of declaring globals in every script file you use the define() function to setup a module. In the definition you also declare what dependencies (requires) that module needs. The AMD loader will load all files asynch, then define each module in the correct order passing in references to each dependency.

What this means for upgrading is that you go from:

Ext:

Ext.namespace("Mobile.SalesLogix.Calendar");
(function() {
    Mobile.SalesLogix.Calendar.MonthView = Ext.extend(Sage.Platform.Mobile.List, {
        // define view
    });
});

To Dojo AMD:

define('Mobile/SalesLogix/Views/Calendar/MonthView', [
    'dojo/_base/declare',
    'dojo/_base/array',
    'dojo/string',
    'dojo/query',
    'dojo/dom-attr',
    'dojo/dom-class',
    'dojo/dom-construct',
    'Mobile/SalesLogix/Format',
    'Sage/Platform/Mobile/ErrorManager',
    'Sage/Platform/Mobile/Convert',
    'Sage/Platform/Mobile/List'
], function(
    declare,
    array,
    string,
    query,
    domAttr,
    domClass,
    domConstruct,
    format,
    ErrorManager,
    convert,
    List
) {

    return declare('Mobile.SalesLogix.Views.Calendar.MonthView', [List], {
        // define view
    });
});

While this does seem to be a lot of extra code the gains far outweigh the additional keystrokes. We now can see what other modules the MonthView requires, we also know the path name and no longer have to memorize global variable names.

To break down the define statement we have:

define('Path/To/My/Script',
    [dependencies],
function(references), {

    /*private space*/

    return declare('My.Module.Name', [Inheritances], {
        /* definition */
    });
});

Path/To/My/Script - This is the path to the script minus the extension. In the index file you can setup shortcuts (namespaces) and in this case Mobile/SalesLogix links to argos-saleslogix/src, so the final path for Month View is: argos-saleslogix/src/Views/Calendar/MonthView.js.

[dependencies - This is an array of other script paths that this module needs to run, again using the shortcuts defined in the index file.

function(references) - This function will recieve an instance of each dependency required. The reason each dependency and reference is on its own line in the code above is to quickly make sure there is a one-for-one match as it needs to go in the same order.

/*private space/* - The code inside here will only be ran once when defined, the returned object will what actually defines the module meaning anything before the return space is private unless exposed in your returned object.

declare() - This is the Ext equivalent of Ext.extend, as it sets up a constructor (factory) to be later used with the new keyword to create instances.

'My.Module.Name' - The name of the module, for our purposes this will match the path used to eliminate confusion.

[Inheritances] - An array of objects that this new module should inherit from - in Dojo terms these are called mixins.

####Notes As seen in the first example you will no longer reference global variables as you have a local variable instance as a reference. Notice in the old Ext code we had:
Sage.Platform.Mobile.List
and now we pull it in as a dependency: Sage/Platform/Mobile/List, get passed a reference: function(,,, List) and then use the List variable:
declare('Mobile.SalesLogix.Views.Calendar.MonthView', [List], ...

This happens for all globals like Mobile.SalesLogix.Format or Sage.Platform.Mobile.Convert - you will see them pulled in and used in code as format and convert.

Naming the references is completely up to the person creating the module but the standard used by SLX Mobile, and in general Dojo, is that constructors (factories) are initial case and everything else is lowercase.

When viewing the Dojo documentation you will want to look for the Dojo 1.7+ example which will show you the path to add as a dependency and the suggested reference name.

###Ext to Dojo Ext has been removed completely, all references to Ext.* and any of it's extended functions such as String.format will need to be replaced with Dojo 1.7.1 equivalents. The following is a short list of typical Ext code used in SLX Mobile and it's Dojo translation:

Ext: Ext.namespace('my.object')
Dojo: No longer required for views. Otherwise, require "dojo/_base/lang" and use lang.setObject('my.object', {})

Ext: Ext.extend()
Dojo: Require "dojo/_base/declare" and use declare()

Ext: Object.superclass.function.apply(this, arguments)
Dojo: this.inherited(arguments). Where this is in the "child" of the inherited object context.

Ext: Ext.override(object, {})
Dojo: Require "dojo/_base/lang" and use lang.extend(object, {})

Ext: String.format('format', arg1, arg2). Where {0} = arg1
Dojo: Require "dojo/string" and use string.substitute('format', [arg1, arg2]). Where ${0} = arg1

Ext: function.createDelegate(scope, [arg1, arg2], bool appendArgs)
Dojo: function.bindDelegate(scope, arg1, arg2)

Ext: Object.on('event', handler, scope)
Dojo: this.connect(object, 'event', handler). Where this is in a View context

Ext: Ext.each(myArray, function(item){}, scope)
Dojo: Require "dojo/_base/array" and use array.forEach(myArray, function(item){}, scope)

Ext: this.el. Where this is in a View context
Dojo: this.domNode. Where this is in a View context

Ext: attachmentPoints: { name : selector }
Dojo: In the actual HTML markup add the attribute: data-dojo-attach-point="name".

###Folder Re-structure With the move to AMD the folder structure has been re-organized and since all module names are based off their physical path the object names themselves have changed.

Folder Name Changes:
argos-sdk/src/Controls to argos-sdk/src/Fields
argos-saleslogix/src/views to argos-saleslogix/src/Views

What this means for your code is if you are referencing Account.Detail like so:
Mobile.SalesLogix.Accout.Detail
it is now:
Mobile.SalesLogix.Views.Account.Detail

The same goes for Controls which are now Fields:
Sage.Platform.Mobile.Controls.BooleanField
to:
Sage.Platform.Mobile.Fields.BooleanField

The following modules have been from from argos-sdk/src/Controls to argos-saleslogix/src/Fields:

  • AddressField
  • NameField
  • PicklistField

With their name change correspondingly:
SalesLogix.Platform.Mobile.Controls.AddressField
to:
Mobile.SalesLogix.Fields.AddressField

###Properties Renamed To better describe several properties they have been renamed to a more intuitive name.

1.2: View.viewTemplate
2.0: View.widgetTemplate
Notes: Simple rename now that all Views are Dojo Dijits

1.2: List.itemTemplate
2.0: List.rowTemplate
Notes: This is the <li> markup for describing the rows structure, not normally changed.

1.2: List.contentTemplate
2.0: List.itemTemplate
Notes: This template sets up the markup for an item within a row (within rowTemplate). This template is overriden every view to be tailored to its entity.

1.2: Detail/Edit createLayout children fields. name is used for SData binding
2.0: Detail/Edit createLayout children fields. name is now the unique identifer, property is for SData binding
Note: This is backward compatible, if property does not exist it will use name for identification and SData binding

###Function Changes

1.2: View.setTitle(value)
2.0: View.set('title', value)
Notes: The function has been removed and replaced with normal get/set.

1.2: View.isActive()
2.0: App.isViewActive(view)
Notes: The View no longer has the function it is globally available in the App namespace.

1.2: App.getActiveView()
2.0: App.getPrimaryActiveView()
Notes: Renamed

###Additional Properties

Detail/Edit createLayout
All objects within layout now have a name property as a unique identifier. This includes sections, quick actions, fields, controls and related views. The purpose of this so in registerCustomization the at: function(row) part can now use row.name to target any piece of the layout.

Hash Tag Customization
Hash Tags now use the same customization engine as detail/edit views, enabling ease of modifying, inserting or removing hash tags.

this.registerCustomization('list/hashTagQueries', 'opportunity_list', {
    at: true, // insert anywhere (hash tag queries are not ordered)
    type: 'insert',
    value: {
        tag: 'g500k',
        query: 'SalesPotential gt "500000"'
    }
});

this.registerCustomization('list/hashTagQueries', 'history_list', {
    // hashes are identified by their key property
    at: function(hash) { return hash['key'] === 'phonecall'; },
    type: 'modify',
    value: {
        query: 'Type eq "atMobileCall"'
    }
});

Toolbar Customization
Toolbars now use the same customization engine as detail/edit views (and hash tags). No longer need to override createToolLayout().

this.registerCustomization('detail/tools', 'account_detail', {
    at: function(tool){ return tool.id === 'edit'; },
    type: 'insert',
    where: 'after',
    value: {
        id: 'customButton',
        icon: 'content/images/icons/Hello_World_24.png',
        action: 'showHelloWorld'
    }
});

Multiple Insert Customizations
Before the registerCustomization engine would only insert one value at a time, causing multiple calls to insert items at the same place. Now you can pass an array for the value key and it will insert each object sequentially at that point.

this.registerCustomization('detail/tools', 'account_detail', {
    at: function(tool){ return tool.id === 'edit'; },
    type: 'insert',
    where: 'after',
    value: [{
        id: 'b1',
        icon: 'content/images/icons/b1.png',
        action: 'b1Function'
    }, {
        id: 'b2',
        icon: 'content/images/icons/b2.png',
        action: 'b2Function'
    }]
});
// results in a toolbar with: [Edit][B1][B2]

View Security
Now that secured actions is available via SData in SalesLogix 8.0+ each individual view now has a security property that can be set to a string defining the secured action required.

When a user logs in the security is stored in:
App.context.userSecurity
as a hash table with each key as the action and the value as true. If a key does not exist in that list it is assumed the user does not have the security permissions to access that view.

Example:
Ticket List may be defined as:

define('...Ticket.List', [], function() { return declare('...Ticket.List', [], {
    security: 'Entities/Ticket/View'
}); });

User Lee has the following actions:

App.context.userSecurity = {
    Entities/Account/View: true,
    Entities/Contact/View: true,
    Entities/Opportunity/View: true
}

and user Barb has these:

App.context.userSecurity = {
    Entities/Account/View: true,
    Entities/Ticket/View: true,
    Entities/Opportunity/View: true
}

When Lee logs in, his Home page will NOT have Tickets and he will not be able to navigate to Tickets in anyway. Even if Account Detail has a "related Tickets" shortcut it will not function. Whereas Barb will have it on her Home page (but not Contacts).

For SalesLogix 7.5.4 and below since it does not reply with a users secured actions it will set the userSecurity to null and grant full access just as before.
