I try to use Ext.Direct with the ExtJS 4 MVC structure, and I'm not able to add the provider.
I get the error Uncaught TypeError: Cannot call method 'addProvider' of undefined
while calling addProvider
:
Ext.Direct.addProvider(Ext.app.REMOTING_API);
I tried both in launch
of the application and in init
of the controller.
Ext.define('Dir.Application', {
require: [
'Ext.direct.*',
'Ext.data.*',
'Ext.grid.*'
],
launch: function(){
Ext.Direct.addProvider(Ext.app.REMOTING_API);
}
...
});
and
Ext.define('Dir.controller.Main', {
init: function(){
Ext.Direct.addProvider(Ext.app.REMOTING_API);
}
...
});
both give the same error.
Where is the correct location to put addProvider
into the code ?
Update: applying the recommendations of @rixo.
Ext.define('Dir.Application', {
view:['Grid'],
requires: [
'Ext.direct.*',
'Ext.data.*',
'Ext.grid.*'
],
launch: function(){
Ext.Direct.addProvider(Ext.app.REMOTING_API);
}
...
});
My view is defining a store and a proxy:
Ext.define('Dir.view.Grid', {
extend: 'Ext.grid.Panel',
store: {
proxy: {
type: 'direct',
reader:{root: 'table'},
api: {
create: QueryDatabase.createRecord,
read: QueryDatabase.getResults,
update: QueryDatabase.updateRecords,
destroy: QueryDatabase.destroyRecord
}
}
...
}
Now the first error is OK, but I receiver an error complaining that QueryDatabase
is not defined. It gets defined through the provider at Ext.Direct.addProvider(Ext.app.REMOTING_API);
but it is not ready when the view is loaded through the views: []
declaration in the application definition.
Is there a way to get this working without nesting Ext.application
inside Ext.onReady
like in my solution?
No nesting would be better for the MVC way like explained here in the docs.
