Intro:
I need to call the backend controller to see if the user is admin. If the user is NOT admin, hide the toolbar in the application. Currently the var is successfully changing; However, it is changing after the view is already created causing the view to always have the toolbar visable.
Problem:
Need to check backend to see if user is in the admin group.
Need to return true if they are in admin group
MyCode:
var adminBool = false;
function CheckAdmin() {
debugger;
var a;
Direct.Report.IsAdmin(this.results, a);
debugger;
};
function results(result, constructor, c, d, e, f, g, h) {
debugger;
this.adminBool= result.adminUser; //returns bool
}
Ext.define('Ext.View.MyViewModel', {
extend: 'Ext.app.ViewModel',
alias: 'viewmodel.AdministrationViewModel',
init: this.CheckAdmin(),
data: {
addNew: true,
update: true,
gridData: null,
isAdmin: this.adminBool
}
});
Synopsis:
Call the backend controller for admin status
Return bool
Update viewModel with bool respectively
ViewModel property,'isAdmin', will bind with hidden property to hide unwanted actions for non admins
UPDATE:
Basically I need a way to delay "isAdmin: this.adminBool" check to after the backend call is finished.
As you are using ViewModel.
So you can use set() method to update your viewmodel field.
I have created an sencha fiddle demo using viewmodel. You can check, how it is working in fiddle. In this fiddle I have not used any API, it just example regarding of ViewModel. Hope this will help you to solve your problem or achieve your requirement.
//ViewModel
Ext.define('MyViewModel', {
extend: 'Ext.app.ViewModel',
alias: 'viewmodel.AdministrationViewModel',
data: {
isAdmin: true
}
});
//Panel
Ext.create('Ext.panel.Panel', {
title: 'ViewModel example',
width: '100%',
renderTo: Ext.getBody(),
viewModel: 'AdministrationViewModel',
layout: {
type: 'vbox', // Arrange child items vertically
align: 'stretch', // Each takes up full width
padding: 10
},
defaults: {
margin: 10
},
items: [{
xtype: 'combo',
height: 40,
fieldLabel: 'Choose Admin or user',
emptyText: 'Choose Admin or user',
labelAlign: 'top',
store: {
fields: ['name', 'value'],
data: [{
"value": true,
"name": "Admin"
}, {
"value": false,
"name": "User"
}]
},
queryMode: 'local',
displayField: 'name',
valueField: 'value',
listeners: {
select: function (combo, record) {
var viewModel = combo.up('panel').getViewModel(),
isAdmin = record.get('value');
//If selected value is {Admin} then we will show toolbar otherwise in case of {User} hide
viewModel.set('isAdmin', !isAdmin);
}
}
}, {
xtype: 'toolbar',
width: '100%',
height: 50,
padding: 10,
bind: {
hidden: '{isAdmin}'
},
items: [{
// xtype: 'button', // default for Toolbars
text: 'Admin',
}, {
xtype: 'splitbutton',
text: 'Split Button'
},
// begin using the right-justified button container
'->', // same as { xtype: 'tbfill' }
{
xtype: 'textfield',
name: 'field1',
emptyText: 'enter search term'
},
// add a vertical separator bar between toolbar items
'-', // same as {xtype: 'tbseparator'} to create Ext.toolbar.Separator
'text 1', // same as {xtype: 'tbtext', text: 'text1'} to create Ext.toolbar.TextItem
{
xtype: 'tbspacer'
}, // same as ' ' to create Ext.toolbar.Spacer
'text 2', {
xtype: 'tbspacer',

}]
});
I am using ExtJs to create a combobox.
Here is my code:
Ext.define('Form.FormTypeDialog', {
extend : 'Ext.Window',
id: 'formTypeDialog',
formId: null,
callbackFunction : null,
modal: true,
statics : {
show : function(formId, callback) {
Ext.create(Form.FormTypeDialog", {
formId : formId,
callbackFunction : callback
}).show();
}
},
constructor : function(config) {
var me = this;
Ext.apply(this, {
buttons : [
{
text:"#{msgs.form_create_dialog_button_cancel}",
cls : 'secondaryBtn',
handler: function() {
me.close();
}
},
{
text:"#{msgs.form_create_dialog_button_next}",
handler: function() {
// Get selected form type
}
}
]
});
this.callParent(arguments);
},
initComponent:function() {
this.setTitle("#{msgs.form_create_dialog_title}");
this.setHeight(175);
this.setWidth(327);
var formTypeStore = Mystore.Store.createRestStore({
url : getRelativeUrl('/rest/form/formTypes'),
root: 'objects',
fields: ['name','value']
});
this.form = new Ext.form.Panel({

bodyBorder:false,
items:[
new Ext.form.Label({
text: "#{msgs.form_create_dialog_select_type_label}",

}),
new Ext.form.ComboBox({

I am creating this window on a xhtml page on a button click using :
Form.FormTypeDialog.show(null, showFormWindowCallBack);
It works fine and combo box is displayed and I can select value.
But if I open and close it 4 times, then in next show it shows the values but It do not allow me to select the last two value. I can only select first value.
Please suggest.
Note: I have tried copying and executing this code in forms of other pages of my application. But behavior is same in all cases.
This combobox is on a Ext.Window.
EDIT:
JSON RESPONSE FROM Rest:
{"attributes":null,"complete":true,"count":3,"errors":null,"failure":false,"metaData":null,"objects":[{"name":"Application
Provisioning Policy Form","value":"Application"},{"name":"Role
Provisioning Policy Form","value":"Role"},{"name":"Workflow

I have re-created this code, I had some errors showing in Firefox using your code directly so I've changed some things.
Running the code below and calling Ext.create("Form.FormTypeDialog", {}).show(); in the console window, then closing the window and repeating does not replicate this issue. Could you try using the code I have and see if you still have the same problem.
Ext.application({

You can also play around with this code using / forking from this Fiddle
It is not clear what your problem is.
I use remote combo follows:
Ext.define('ComboRemote', {
extend: 'Ext.form.ComboBox',
xtype: 'ComboRemote',
emptyText: 'empty',
width: 75,
displayField: 'name',
valueField: 'id',
store: {
model: 'ComboModel',
proxy: {
type: 'rest',
url: '/serv/Res',
extraParams: {
query: ''
},
reader: {
root: "result", type: 'json'
}
},
autoLoad: true,
},
queryMode: 'remote',
pageSize: false,
lastQuery: '',
minChars: 0});
Ext.define('ComboModel', {
extend: 'Ext.data.Model',
fields: [
'id',
'name'
]});
I hope to help
Try these possible solutions
1. Make AutoLoad property for store as true.
2. Add delay of some ms
I am creating a Sencha touch xtype, it will contain an invisible input file and a button; I would like to trigger the popup to choose a file when the button is pressed. This is what I've done so far:
config: {
baseCls: 'imageFileField',
layout: 'hbox',
items: [
{
xtype: 'label',
baseCls: Ext.baseCSSPrefix + 'form-label'
},
{
xtype: 'container',
layout: 'hbox',
flex: 1,
items: [
{
xtype: 'filefield',
hidden: true,
listeners: {
afterrender: function (cmp) {
cmp.fileInputEl.set({
accept: 'image/*'
});
}
}
},
{
xtype: 'label',
baseCls: Ext.baseCSSPrefix + 'form-label'
},
{
xtype: 'button',
margin: '5px',
docked: 'right',
ui: 'base_button',
iconCls: '',
width: '50px',
listeners: {
tap: function (view, e, eOpts) {
}
}
}
]
}
]
},
I know I should put something within the tap method, to navigate to the item and then trigger the event. I tried using this.up()/down(...) but I've never been able to get the invisible input. What is the right "path" to get there?
You can use Ext.ComponentQuery to find you element and set its properties. To find your element you have to first assign itemId to it.
xtype: 'filefield',
hidden: true,
itemId: 'chooseFile',
listeners: {
afterrender: function (cmp) {
cmp.fileInputEl.set({
accept: 'image/*'
});
}
}
Then you can put the following code in your button's listener event.
listeners: {
tap: function (view, e, eOpts) {
Ext.ComponentQuery.query("container > #chooseFile").show();
}
}
I have put all the controls in the controller and its working correctly:-
refs: {
filefield: 'filefield[name="fileField"]',
fileBtn: 'button[name="fileBtn"]'
},
control: {
"fileBtn": {
tap: function() {
this.getFilefield().show();
}
}
}
I have a FormPanel (See below) that has several functions defined.
I need to call one function from another function, but I get error that
the function I am calling is undefined.
If I call the ShowInspections from the OnMyButtonTap function it works
If I call the ShowInspections from the LoginOk function it DOES NOT work
I am at a loss I believe it is a scope issue, but so new it Sencha I really need
some help.
Ext.define('MyApp.view.LoginPanel', {
extend: 'Ext.form.Panel',
alias: 'widget.Login',
config: {
items: [
{
xtype: 'fieldset',
height: 226,
width: 440,
title: 'Enter Login Information',
items: [
{
xtype: 'textfield',
id: 'userid',
label: 'User ID',
labelWidth: '40%',
required: true
},
{
xtype: 'textfield',
id: 'pswd',
label: 'Password',
labelWidth: '40%',
required: true
}
]
},
{
xtype: 'button',
height: 86,
itemId: 'mybutton',
text: 'Login'
}
],
listeners: [
{
fn: 'onMybuttonTap',
event: 'tap',
delegate: '#mybutton'
}
]
},
onMybuttonTap: function(button, e, options) {
doLogin(Ext.getCmp('userid').getValue(),Ext.getCmp('pswd').getValue(),this.LoginOk,this.LoginFail,this.LoginError);
},
LoginOk: function() {
//
// this function is called from doLogin and it works
//
//GetInspections('01/01/2011','12/31/2012','','',this.ShowInspections,this.LoadDataFail,this.LoadDataError);
// the function GetInspections does work, but does not call the "ShowInspections" function
this.ShowInspection); // directly calling this function does NOT work either
},
LoginFail: function() {
Ext.Msg.alert('Invalid User ID and/or Password.');
},
LoginError: function() {
Ext.Msg.alert('Login Error!');
},
LoadDataFail: function() {
Ext.Msg.alert('No Inspections found.');
},
LoadDataError: function() {
Ext.Msg.alert('Error Loading Inspections.');
},
ShowInspections: function() {
Ext.Msg.alert('got inspections');
}
});
There is some typo in the current code.
this.ShowInspection);
should read as
this.ShowInspections();
Isn't that your problem?
You have missed () everywhere you just need to change as this.LoginOk(), this.LoginFail() etc and this.ShowInspections()
I created the following grid component:
MyApp.grids.RelationshipMemberGrid = Ext.extend(Ext.grid.GridPanel, {
autoHeight: true,
iconCls: 'icon-grid',
title: 'Relationship Members',
frame: true,
viewConfig: { forceFit: true },
relationshipId: null,
documentId: null,
initComponent: function () {
if (this.verifyParameters()) {
// Initiate functionality
this.columns = this.buildColumns();
this.view = this.buildView();
this.store = this.buildStore();
this.store.load();
}
MyApp.grids.RelationshipMemberGrid.superclass.initComponent.call(this);
},
verifyParameters: function () {
// Verification code
},
buildColumns: function () {
return [{
header: 'Id',
dataIndex: 'Id',
sortable: true,
width: 10
}, {
header: 'Type',
dataIndex: 'ObjType',
sortable: true,
width: 10
}, {
header: 'Name',
dataIndex: 'Name',
sortable: true
}];
},
buildView: function () {
return new Ext.grid.GroupingView({
forceFit: true,
groupTextTpl: '{text} ({[values.rs.length]} {[values.rs.length > 1 ? "Members" : "Member"]})'
});
},
buildStore: function () {
return new Ext.data.GroupingStore({
url: MyAppUrls.ListRelationshipMembers,
baseParams: { relationshipId: this.relationshipId },
root: 'data',
fields: ['Id', 'ObjType', 'Name'],
sortInfo: { field: 'Name', direction: 'ASC' },
groupField: 'ObjType'
});
}
});
The grid renders correctly, and the URL that is mapped to MyAppUrls.ListRelationshipMembers is correct. The data is being retrieved, and the ListRelationshipMembers URL is returning the following JSON:
{"data":[{"Id":1,"ObjType":"topic","Name":"Test2"}]}
Yet, even though the grid is rendered (columns, borders, etc..) no data is showing in the actual grid though. Since this is my first time using a data store, I am unsure of what I am doing wrong. Any help would be appreciative.
Edit:
I tried updating the store to have a reader via the following code:
return new Ext.data.GroupingStore({
url: MyAppUrls.ListRelationshipMembers,
baseParams: { relationshipId: this.relationshipId },
fields: ['Id', 'ObjType', 'Name'],
sortInfo: { field: 'Name', direction: 'ASC' },
reader: new Ext.data.JsonReader({
root: 'data'
}),
groupField: 'ObjType'
});
No change, the datagrid is not being filled with the records
Evan is correct. Your biggest problem is a lack of a reader. That and the validation stub you left in there needed to return true. If you can't just drop this code in and have it work you have some other problem.
MyApp.grids.RelationshipMemberGrid = Ext.extend(Ext.grid.GridPanel, {
autoHeight: true,
iconCls: 'icon-grid',
title: 'Relationship Members',
frame: true,
viewConfig: { forceFit: true },
relationshipId: null,
documentId: null,
initComponent: function () {
if (this.verifyParameters()) {
// Initiate functionality
this.columns = this.buildColumns();
this.view = this.buildView();
this.store = this.buildStore();
this.store.load();
}
MyApp.grids.RelationshipMemberGrid.superclass.initComponent.call(this);
},
verifyParameters: function () {
// Verification code
return true;
},
buildColumns: function () {
return [{
header: 'Id',
dataIndex: 'Id',
sortable: true,
width: 10
}, {
header: 'Type',
dataIndex: 'ObjType',
sortable: true,
width: 10
}, {
header: 'Name',
dataIndex: 'Name',
sortable: true
}];
},
buildView: function () {
return new Ext.grid.GroupingView({
forceFit: true,
groupTextTpl: '{text} ({[values.rs.length]} {[values.rs.length > 1 ? "Members" : "Member"]})'
});
},
buildStore: function () {
return new Ext.data.GroupingStore({
url: MyAppUrls.ListRelationshipMembers,
baseParams: { relationshipId: this.relationshipId },
reader: new Ext.data.JsonReader({
root: 'data',
fields: ['Id', 'ObjType', 'Name'],
sortInfo: { field: 'Name', direction: 'ASC' },
groupField: 'ObjType'
})
});
}
});
Think you need to do a couple of things here: firstly, as mentioned by Evan, you need to add a reader to your store, like this:
buildStore: function () {
return new Ext.data.Store({
url: MyAppUrls.ListRelationshipMembers,
baseParams: { relationshipId: this.relationshipId },
fields: ['Id', 'ObjType', 'Name'],
sortInfo: { field: 'Name', direction: 'ASC' },
reader: new Ext.data.JsonReader({
root: 'data'
})
});
}
I've changed the store type here to something simpler - was there a particular reason you were using GroupingStore? Note that the root is specified in the reader, not the store itself.
Then, in your columns, I'd tend to add a renderer to explicitly determine what each column will display, such as:
buildColumns: function () {
return [{
header: 'Id',
dataIndex: 'Id',
sortable: true,
width: 10,
renderer: function (value, metaData, record) {
return record.data.Id
}
} ... ];
}
I've got into the habit of using renderers, since I modify the content of my column cells quite heavily in my grids. Notice here the arguments being passed to the renderer function; there are a few more you can pass in - see the ExtJS API if you need more info on what you can actually access. On that note, the API documentation is pretty good - it can take some digging into but definitely worth your time if you're working with ExtJS a lot.
You haven't specified a reader on your store, you need to specify the root in the JsonReader.
