So I've a problem 'cause i want to show parent data on grid, illustrated here:
PARENT MODEL
Ext.define('Ab.model.Marca', {
extend: 'Ext.data.Model',
fields: ['id','nombre'],
hasMany: {model: 'Ab.model.Maquina', name: 'maquina'},
proxy{...}
});
CHILD MODEL
Ext.define('Ab.model.Maquina', {
extend: 'Ext.data.Model',
fields: ['id','nombre', 'codigo', 'estado'],
associations: [
{type:'belongsTo', model:'Ab.model.Marca', name: 'marca'},
]
proxy:{...}
});
CHILD GRID
Okay, MaquinaController execute load from Store and that is not important 'cause load informations very nice. The problem is that I can't show parent data.
Ext.define('Ab.view.maquina.MaquinaList', {
extend: 'Ext.grid.Panel',
alias: 'widget.maquinalist',
store: 'Maquinas',
columns: [
{ text: _('Nombre'), flex: 1, dataIndex: 'nombre' },
{ text: _('Código Externo'), flex: 1, dataIndex: 'codigo' },
{ text: _('Estado'), flex: 1, dataIndex: 'estado' },
{ text: _('Marca'), flex: 1, dataIndex: 'marca' } <<< HOW CAN I SHOW MARCA?
]
});
Thanks in advance.
Override column.renderer , and return record.getParent().get('someData');
http://docs.sencha.com/ext-js/4-1/#!/api/Ext.grid.column.Column-cfg-renderer
renderer: function(value, metadata, record, rowIndex, colIndex, store, view){
return record.getMarca().get('nombre');
}
Also, make sure you are following the rules:

I'm trying to create a view, which has essentially a list where each row has text and 2 buttons aligned right. The text of the buttons will always be the same - only the text of the row will need to be fetched from the store.
I saw this question but couldn't get the proposed solution to work. I definitely have records in my store, but the dataview does not display.
A simplified version of my code:
My main view:
Ext.define('MyApp.view.Main', {
extend: 'Ext.Container',
...
config: {
layout: {
type: 'vbox',
pack: 'center',
align: 'middle'
},
items: [
...
{xtype: 'mylist'}
...
]
...
}
...
});
DataView:
Ext.define('MyApp.view.MyList', {
extend: 'Ext.dataview.DataView',
alias: 'widget.mylist',
requires: ...,
config: {
useComponents: true,
store: 'my-store',
defaultType: 'listitem'
}
});
DataItem:
Ext.define('MyApp.view.ListItem', {
extend: 'Ext.dataview.component.DataItem',
alias: 'widget.listitem',
config: {
layout: ...
items: [{
xtype: 'component',
itemId: 'description',
html: '',
flex: 2
},
{
xtype: 'button',
text: 'a button',
itemId: ...,
flex: ...
},
{
... another button
}]
},
updateRecord: function(record) {
...
this.down('#description').setHtml(record.get('description'));
// record.get('description') does give me an undefined value
}
});
Assuming my stores and models are set up properly, what could the problem be?
Alternatively, maybe I should just use a standard list, but set the width to <100%, and just add 2 buttons to the right for each row. Though I'd rather get the current approach to work...
Edit:
Ended up using the dataMap approach.
My DataItem now looks like:
config: {
layout: {
type: 'hbox',
align: 'center'
},
dataMap: {
getDescription: {
setHtml: 'description'
}
},
description: {
flex: 1
}
},
applyDescription: function(config) {
return Ext.factory(config, Ext.Component, this.getDescription());
},
updateDescription...
Basically like this.
I see the labels now, but am stuck on how to get a button in there. Since I don't want to link it to a store, I don't want to put it in the dataMap. I tried putting it in items, but to no avail.
Edit 2:
Well, getting the button to display was easier than I thought. It's just a repeat of what I did with the label, but without including it in the dataMap - yesButton: {...}, applyYesButton: f(){...}, updateYesButton: f(){...}...
The last issue I need to resolve is, how to uniquely identify them. I want a listener on the button, but somehow pass in the record into the handler.
My solution for getting a button in a dataview without linking it to the store. It's actually, somewhat unsurprisingly, similar to this blog post.
view - ListItem.js
...
config: {
layout: {
type: 'hbox',
align: 'center'
},
dataMap: {
getDescription: {
setHtml: 'description'
}
},
description: {
cls: ...,
flex: 4
},
myButton: {
cls: ...,
text: 'Button!',
flex: 1
}
},
applyDescription, updateDescription (same as in the question),
applyMyButton: function(config) {
return Ext.factory(config, Ext.Button, this.getMyButton());
},
updateMyButton: function(newButton, oldButton) {
... same logic as the other update method
}
In my dataview:
...
config: {
itemId: ...,
store: ...,
useComponents: true,
defaultType: 'listitem',
width: '100%',
flex: 1,
listeners: {
itemtap: function(dataview, index, element, evt) {
var store = dataview.getStore();
var record = store.getAt(index);
...
}
}
}
...
I got this class where I'm trying to show some data from the same store in the same container. I did it this way because I want to have two rows each on a separate line and I was not having
too much control over them. Here's the class:
Ext.define('Clue.view.ListQuestions', {
extend: 'Ext.Container',
requires: ['Ext.dataview.List'],
xtype: 'listquestions',
config: {
id: 'listquestions',
items: [{
xtype: 'list',
id: 'questionLi1',
baseCls: 'questionLi1',
flex: 1,
store: {
xtype: 'levelstore',
filters: [{
filterFn: function(item) {
return item.data.levelId < 2 && item.data.questionId < 6;
}
}]
},
itemTpl: '<div>{questionId}</div>'
},{
xtype: 'list',
id: 'questionLi2',
baseCls: 'questionLi2',
flex: 1,
store: {
xtype: 'levelstore',
filters: [{
filterFn: function(item) {
return item.data.levelId < 2 && item.data.questionId > 5;
}
}]
},
itemTpl: '<div>{questionId}</div>'
}]
}
})
If I remove the second list, first list is showing, otherwise the first list is not showing. What I'm doing wrong ?
here's the store:
Ext.define('Clue.store.LQuestions', {
extend: 'Ext.data.Store',
xtype: 'levelstore',
requires: ['Ext.data.proxy.LocalStorage'],
config: {
model: 'Clue.model.LQuestions',
storeId: 'levelStore',
sorters: [{
property: 'levelId',
direction: 'ASC'
}],
proxy: {
type: 'localstorage',
id: 'levelstorage'
}
}
})
other details
I added some css on the questionLi1 and questionLi2 and their items. 3px red border. the lists are taking space but in the first list elements are not there ( not even in html ) second list is rendered fine. if I put a console.log() in the first filterFn function nothing shows up.. so I was thinking that maybe I overwrite something...
this is what I get
and if I do:
...
flex: 1,
/*store: {
xtype: 'levelstore',
filters: [{
filterFn: function(item) {
return item.data.levelId < 2 && item.data.questionId > 5;
}
}]
},*/
itemTpl: '<div>{questionId}</div>'
...
on the second list I get
Adding a flex config to a component only works if you specify a vbox of hbox layout to its parent like so
Ext.create('Ext.Container', {
fullscreen: true,
layout: 'vbox',
items: [{
xtype: 'list',
itemTpl: '{title}',
flex: 1,
data: [
{ title: 'List 1: Item 1' },
{ title: 'List 1: Item 2' },
{ title: 'List 1: Item 3' },
{ title: 'List 1: Item 4' }
]
}, {
xtype: 'list',
itemTpl: '{title}',
flex: 1,
data: [
{ title: 'List 2: Item 1' },
{ title: 'List 2: Item 2' },
{ title: 'List 2: Item 3' },
{ title: 'List 2: Item 4' }
]
}]
});

I need the tab-panels to fit browser window size. I have used card layout, and it is not re-sizing to fit the browser window. I think i'm missing some properties in my viewPort.
launch: function() {
Ext.create('Ext.container.Viewport', {
layout: 'card',
items: [
{
xtype: 'panel',
items: { xtype: 'tabP1' }
},
{
xtype: 'panel',
items: { xtype:'tabP2' }
}
,
{
xtype: 'panel',
items: { xtype:'tabP3' }
}
]
});
},
2.) One of my tabpanels; I am using absolute layout. I am using this layout because it's easy to set form components where i ever i desire it to be. Therefore, i would like a solution that works with the same layout.
Ext.define('MyApp.view.MyForm', {
extend: 'Ext.form.Panel',
alias:'widget.tabP1',
// height: 250,
// width: 726,
layout: {
type: 'absolute'
},
bodyPadding: 10,
title: 'My Form',
initComponent: function() {
var me = this;
Ext.applyIf(me, {
items: [
{
xtype: 'gridpanel',
title: 'My Grid Panel',
columns: [
{
xtype: 'gridcolumn',
dataIndex: 'string',
text: 'String'
},
{
xtype: 'numbercolumn',
dataIndex: 'number',
text: 'Number'
},
{
xtype: 'datecolumn',
dataIndex: 'date',
text: 'Date'
},
{
xtype: 'booleancolumn',
dataIndex: 'bool',
text: 'Boolean'
}
],
viewConfig: {
}
}
]
});
me.callParent(arguments);
}
});

UPDATE 2
launch: function() {
Ext.create('Ext.container.Viewport', {
layout: 'card',
items: [

I get an error when i use your code, saying that this.getViewport().getLayout().setActiveItem(1) is not a function. I think this is because i used border layout. How can i resolve this ?
Your problem is "over-nesting" Why are you putting 'tabPFoo' inside a panel with no layout? They are at best, redundant, also causing the layout system to spend more cycles when it's not needed.
Ext.require('*');
Ext.onReady(function(){
var vp = new Ext.container.Viewport({
layout: 'card',
items: [{
xtype: 'grid',
store: {
fields: ['name'],
data: [{
name: 'Name 1'
}]
},
columns: [{
flex: 1,
dataIndex: 'name',
text: 'Name'
}],
listeners: {
itemclick: function(view){
var grid = view.ownerCt,
next = grid.nextSibling();
vp.getLayout().setActiveItem(next);
}
}
}, {
xtype: 'grid',
store: {
fields: ['name'],
data: [{
name: 'Name 2'
}]
},
columns: [{
flex: 1,
dataIndex: 'name',
text: 'Name'
}],
listeners: {
itemclick: function(view){
var grid = view.ownerCt,
next = grid.nextSibling();
vp.getLayout().setActiveItem(next);
}
}
}, {
xtype: 'grid',
store: {
fields: ['name'],
data: [{
name: 'Name 3'
}]
},
columns: [{
flex: 1,
dataIndex: 'name',
text: 'Name'
}],
listeners: {
itemclick: function(view){
var grid = view.ownerCt,
next = grid.previousSibling().previousSibling();
vp.getLayout().setActiveItem(next);
}
}
}]
});
});
Obviously that's not MVC style, but that's the structure the layout should take.
What I'm trying to do here is to use a card layout within the panel of a carousel. But it seems impossible that it's not common to create a card layout and the carousel is actually one of the card-layout-like container. So I wonder if it can be achieved in Sencha Touch 2.
Here is my main view, a plain carousel container:
Ext.define("myapp.view.Main", {
extend: 'Ext.carousel.Carousel',
config: {
defaults: {
styleHtmlContent : true
},
activeItem: 0,
items: [
{
xtype: 'firstview'
},
{
xtype: 'secondview'
},
{
xtype: 'thirdview'
}
]
}
});
and here is my 'firstview', which extends the Ext.Panel as part of the carousel container:
Ext.define("myapp.view.Compose", {
extend: 'Ext.Panel',
xtype: 'firstview',
requires: [
'Ext.form.FieldSet',
'Ext.TitleBar',
'Ext.form.Text',
'Ext.Button'
],
config: {
styleHtmlContent: true,
scrollable: true,
layout: 'vbox',
items: [
{ // title bar
xtype: 'titlebar',
docked: 'top',
title: 'a Title here'
},
{
xtype: 'toolbar',
docked: 'top',
layout: {
type: 'vbox',
align: 'center',
pack: 'center'
},
items: [
{ // controll button set - to change view for composing different kinds of messages
xtype: 'segmentedbutton',
allowDepress: true,
allowMultiple: false,
items: [
{
text: 'subview-1',
pressed: true
},
{
text: 'subview-2'
},
{
text: 'subview-3'
}
]
}
]
},
{
xtype: 'container',
id: 'id_compose_card',
layout: {
type: 'card',
align: 'center',
pack: 'top'
},
config: {
height: '100%',
items: [
{
html: 'card 1'
},
{
html: 'card 2'
}
]
}
}
]
}
});
as you can see, there is a card layout within this panel. But as a matter of fact nothing is not going to display.
Of course, I can find another way out to achieve some thing similar here, but I just want to know is it impossible to embed a card container into a card-layout-like container, for example, 'tabPanel' or 'carousel' in sencha touch 2?
Hey in the Compose widget replace the the part with id:'id_compose_card'
with this
{
xtype: 'container',
id: 'id_compose_card',
layout: {
type: 'card',
align: 'center',
pack: 'top'
},
flex: 1,
items: [
{
html: 'card 1'
},
{
html: 'card 2'
}
]
}
I just took out the parts inside the config object and put them outside. Im getting this feeling that u cant nest a config inside another config object for a class definition. A lot of people are having issue and this seems to be the problem. You might want to confirm this on their forum.
Then I also replaced the attribute
height: '100%',
with this
flex:1
This will tell the vbox layout to make your component fill the remaining space.
In a small program that I have, I'm trying to have custom containers for every leaf node of my Nested List.
Here are a couple arbitrary example containers that I'm trying to test with:
Ext.define('DetailContainer1', {
extend: 'Ext.Container',
xtype: 'detail-container1',
layout: {
type: 'vbox'
},
height: 300,
style: 'background-color: #a9a9a9;',
// flex: 1,
items: [{
html: 'Detail Container1'
}]
});
Ext.define('DetailContainer2', {
extend: 'Ext.Container',
xtype: 'detail-container2',
layout: {
type: 'vbox'
},
height: 300,
style: 'background-color: #c9c9c9;',
// flex: 1,
items: [{
html: 'Detail Container2',
flex: 1
}, {
xtype: 'button',
text: 'Hit me!',
flex: 1
}]
});
How can I switch in the new containers when the user clicks on the leaf node?
This action should happen in onLeafItemTap(). Btw the initial container (#2) isn't showing at the moment. Is this a layout issue?
Here's some idea of what the screen should look like:
Complete source:
Ext.Loader.setConfig({
enabled: true
});
Ext.define('DetailContainer1', {
extend: 'Ext.Container',
xtype: 'detail-container1',
layout: {
type: 'vbox'
},
height: 300,
style: 'background-color: #a9a9a9;',
// flex: 1,
items: [{
html: 'Detail Container1'
}]
});
Ext.define('DetailContainer2', {
extend: 'Ext.Container',
xtype: 'detail-container2',
layout: {
type: 'vbox'
},
height: 300,
style: 'background-color: #c9c9c9;',
// flex: 1,
items: [{
html: 'Detail Container2',
flex: 1
}, {
xtype: 'button',
text: 'Hit me!',
flex: 1
}]
});
Ext.define('ListItem', {
extend: 'Ext.data.Model',
config: {
fields: ['text']
}
});
Ext.define('Sencha.view.MainView', {
extend: 'Ext.Container',
xtype: 'mainview',
layout: {
type: 'hbox'
},
initialize: function() {
this.treeStore = Ext.create('Ext.data.TreeStore', {
model: 'ListItem',
defaultRootProperty: 'items',
root: {
items: [{
text: 'Containers',
items: [{
text: 'Detail #1',
leaf: true
}, {
text: 'Detail #2',
leaf: true
}]
}]
}
});
this.detailContainer = Ext.create("DetailContainer2", {});
this.nestedList = Ext.create('Ext.NestedList', {
docked: 'left',
width: 300,
flex: 1,
store: this.treeStore,
detailCard: true,
detailContainer: this.detailContainer,
listeners: {
scope: this,
leafitemtap: this.onLeafItemTap
}
});
this.setItems([this.detailContainer, this.nestedList]);
},
onLeafItemTap: function(nestedList, list, index, node, record, e) {
var detailCard = nestedList.getDetailCard();
// nestedList.setDetailContainer(Ext.create("DetailContainer1", {}))
// detailCard.setHtml(record.get('text') + "...");
}
});
Ext.application({
launch: function() {
var container = Ext.create("Ext.Container", {
layout: {
type: 'hbox'
},
items: [{
xtype: 'mainview'
}]
});
Ext.Viewport.add(container);
}
});
Finally I've figured out the proper way to solve your problem.
Some explanations:
If you want to display "customized detailContainer" at the right side of your hbox, it's quite obvious that you should disable detailCard config for your Ext.NestedList because it's designed to display inline (i.e. take place of your Ext.NestedList).
When using Ext.define, everything should be included in config (except extend, xtype, alias, id, so in this case, layout has to be put in config).
flex should be defined in config as well.
At leafitemtap event, simply update your detailContainer config and remove/add it again as it would not be updated dynamically.
Please take a look at modified code snippet below, it works perfectly for me.
Ext.Loader.setConfig({ enabled: true });
Ext.define('DetailContainer1', {
extend: 'Ext.Container',
xtype: 'detail-container1',
config: {
flex: 1,
layout: {
type: 'vbox'
},
style: 'background-color: #a9a9a9;',
items: [
{html: 'Detail Container1'}
]
}
});
Ext.define('DetailContainer2', {
extend: 'Ext.Container',
xtype: 'detail-container2',
config: {
flex: 1,
layout: {
type: 'vbox'
},
style: 'background-color: #c9c9c9;',
items: [
{html: 'Detail Container2', flex: 1},
{xtype: 'button', text: 'Hit me!', flex: 1}
]
}

mainview = Ext.getCmp('mainview');
if (index==0) {
mainview.detailContainer = Ext.create("DetailContainer1");
} else {
mainview.detailContainer = Ext.create("DetailContainer2");
