Sencha touch: nested list with multiple root properties - javascript

I'm trying to display the JSON structure shown below in a nested list. Each category has a name and consists of subcategories and leafs.
{
name: 'root',
categories: [
{
name: 'Category 1',
categories: [
{
name: 'Category 1.1',
leafs: [
{ name: 'Leaf 1.1.1', leaf: true },
{ name: 'Leaf 1.1.2', leaf: true }
]
}
],
leafs: [
{ name: 'Leaf 1.1', leaf: true },
{ name: 'Leaf 1.2', leaf: true }
]
},
{
name: 'Category 2',
leafs: [
{ name: 'Leaf 2.1', leaf: true },
{ name: 'Leaf 2.2', leaf: true }
]
}
]
}
The data model is the following:
Ext.define('MyApp.model.Leaf', {
extend: 'Ext.data.Model',
config: {
fields: [
{name: 'name', type: 'string'}
]
}
});
Ext.define('MyApp.model.Category', {
extend: 'Ext.data.Model',
//requires: ['MyApp.model.Leaf'],
config: {
fields: [
'id', 'name'
],
hasMany: [
{
model: 'MyApp.model.Category',
name: 'categories',
associationKey: 'categories'
},
{
model: 'MyApp.model.Leaf',
name: 'statistics',
associationKey: 'leafs'
}
],
proxy: {
type: 'ajax',
url : 'http://192.168.178.103?data',
reader: {
type: 'json',
rootProperty: 'categories'
}
}
}
});
And here is the nested list:
{
xtype: 'nestedlist',
title: 'Kategorien',
displayField: 'name',
store: Ext.create('Ext.data.TreeStore', {
model: 'MyApp.model.Category'
})
}
The problem is: The nested list shows me all categories und their child categories correctly, but I'm not able to get the leafs displayed. I think the reason is that the identifier of the leaf array is named 'leafs' and therefor is not recognized but i can only give one root property identifier.
Any ideas? Thanks in advance.

Conditionally Filter Options for References in Sanity IO

I have 3 schema,
Menu
Section
Sub-Section
i want to conditionally filter the list of options provided based on the current object. Lets say i want to create a new sub-section which is under Pizza Menu so i will input Menu: Pizza (I created it before) and so section input should only accept and display all the available sections under pizza menu only.
Code:
subSection.js
export default {
name: 'sub-section',
title: 'Sub-Section',
type: 'document',
fields: [
{ name: 'title', type: 'string' },
{ name: 'description', type: 'string' },
{
name: 'menu',
type: 'reference',
to: [{ type: 'menu' }],
},
{
name: 'section',
type: 'reference',
to: [{ type: 'section' }],
options: {
filter: 'menu == references($menu)', // this does not work
filterParams: { menu: 'Neopolitan' }, // ^ ^ This is static, cannot reference current object
},
},
],
};
section.js
export default {
name: 'section',
title: 'Section',
type: 'document',
fields: [
{ name: 'title', type: 'string' },
{ name: 'description', type: 'string' },
{
name: 'menu',
type: 'reference',
to: [{ type: 'menu' }],
},
],
};
menu.js
export default {
title: 'Menu',
name: 'menu',
type: 'document',
fields: [
{
title: 'Title',
name: 'title',
type: 'string',
},
],
};

Sanity.io reusable schema field types

I'm new to Sanity.io. I'm just wondering if there is a way that I can optimize my codes and reuse the fields in different schemas.
Im thinking something like this:
cars.ts:
export default {
name: 'cars',
title: 'Cars',
type: 'document',
fields: [vehicleName]
}
trucks.ts:
export default {
name: 'trucks',
title: 'Trucks',
type: 'document',
fields: [vehicleName]
}
vehicleName.ts:
export const vehicleName = {
name: 'name',
title: 'Name',
type: 'string',
validation: Rule => Rule.required()
}
{
title: 'Vehicle Names',
name: 'vehicles',
type: 'array',
of: [
{
type: 'reference',
to: [
{type: 'cars'},
{type: 'trucks'}
]
}
]
}
You can use references to access the cars and trucks in as many different schemas as you want making your code reusable
export default {
name: 'trucks',
title: 'Trucks',
type: 'array',
fields: [
{
title: 'Names',
name: 'names',
type: 'reference',
to: [{type: 'vechicleName'}]
}
]
}
Sanity is bi-directional

Create two grids in seperated panels - Ext JS

I want to make two grids in two side-by-side panels. I tried with following code:
Ext.define('BlackWhiteList', {
extend: 'Ext.panel.Panel',
xtype: 'blackwhitelist',
layout: {
type: 'table',
columns: 2,
tableAttrs: {
style: {
width: '100%'
}
}
},
defaults: {
border: false
},
fieldDefaults: {
labelWidth: 110,
anchor: '100%'
},
items: [{
title: 'Black List',
cls: 'blackList',
items: [
grid
]
},
{
title: 'White List',
items: [
grid
]
}
]
});
var store = Ext.create('Ext.data.Store', {
storeId: 'simpsonsStore',
fields: ['name', 'email', 'phone'],
data: [
{ name: 'Lisa', email: 'lisa#simpsons.com', phone: '555-111-1224' },
{ name: 'Bart', email: 'bart#simpsons.com', phone: '555-222-1234' },
{ name: 'Homer', email: 'homer#simpsons.com', phone: '555-222-1244' },
{ name: 'Marge', email: 'marge#simpsons.com', phone: '555-222-1254' }
]
});
var grid = Ext.create('Ext.grid.Panel', {
store: store,
columns: [
{ text: 'Name', dataIndex: 'name' },
{ text: 'Email', dataIndex: 'email', flex: 1 },
{ text: 'Phone', dataIndex: 'phone' }
]
});
But at the moment in only shows me the title "Black List" and "White List" with empty content. I get no error messages or anything which can show me what is wrong here.
I use ExtJS 6.
This is really a tricky question, You will need to fix 2 things in your code so that your code work.
First is how you are defining the grid and where you used it, the a/m code will yield undefined value for the grid by the time of execution. why? this is related to hoisting in JS, the JS will recognize the grid variable but will not assign it's value so when you are creating your Ext panel you have grid value equals to undefined.
So first thing is to move the var grid block of code to the top.
But now you will face a 2nd problem you will see only one grid is rendered, why?
Because the grid is an object which is reference type, and this will make the two panels try to show the same grid and this is impossible so it is shown only on one place.
So to fix this problem you need to use Ext.define for the grid and assign xtype to it, so when you use xtype in the panel more than one time Ext will create 2 complete diffrent instance of your grid. Or you can make var grid1 and var grid2 but this is not good
Finally a working example Fiddle
Code Sample
App.js
Ext.application({
name: 'Test',
requires: ['Test.MyGrid'],
launch: function () {
Ext.create('Ext.panel.Panel', {
renderTo: Ext.getBody(),
layout: {
type: 'table',
columns: 2,
tableAttrs: {
style: {
width: '100%'
}
}
},
defaults: {
border: false
},
fieldDefaults: {
labelWidth: 110,
anchor: '100%'
},
items: [{
title: 'Black List',
cls: 'blackList',
items: [{
xtype: 'myGrid'
}]
}, {
title: 'White List',
items: [{
xtype: 'myGrid'
}]
}
]
});
}
});
app/MyGrid.js
var store = Ext.create('Ext.data.Store', {
storeId: 'simpsonsStore',
fields: ['name', 'email', 'phone'],
data: [
{ name: 'Lisa', email: 'lisa#simpsons.com', phone: '555-111-1224' },
{ name: 'Bart', email: 'bart#simpsons.com', phone: '555-222-1234' },
{ name: 'Homer', email: 'homer#simpsons.com', phone: '555-222-1244' },
{ name: 'Marge', email: 'marge#simpsons.com', phone: '555-222-1254' }
]
});
Ext.define('Test.MyGrid', {
extend:'Ext.grid.Panel',
store: store,
xtype:'myGrid',
columns: [
{ text: 'Name', dataIndex: 'name' },
{ text: 'Email', dataIndex: 'email', flex: 1 },
{ text: 'Phone', dataIndex: 'phone' }
]
});
Hope I made things clear :)

How to use ExtJS 5 Ext.data.Model Field reference (in comparison to belongsTo in ExtJS 4)

I use belongsTo in an Ext.data.Model and it works like charm, thread.getCustomer(function(record) {[…]}) loads a customer:
Ext.define('MyApp.model.Thread', {
extend: 'MyApp.model.Base',
requires: [
'MyApp.model.Customer'
],
idProperty: 'thread_id',
fields: [
{name: 'thread_id', type: 'int'},
{name: 'thread_customer_id',type: 'int'},
],
belongsTo: {
model: 'MyApp.model.Customer',
name: 'Customer',
primaryKey: 'customer_id',
foreignKey: 'thread_customer_id'
}
});
However, I get a warning from Ext:
[W] Use of "belongsTo" is obsolete in MyApp.model.Thread
I tried to translate it to a reference in the field definition:
Ext.define('MyApp.model.Thread', {
extend: 'MyApp.model.Base',
requires: [
'MyApp.model.Customer'
],
idProperty: 'thread_id',
fields: [
{name: 'thread_id', type: 'int'},
{
name: 'thread_customer_id',
type: 'int',
reference: 'MyApp.model.Customer'
}
]
});
or
reference: {
type: 'MyApp.model.Customer',
role: 'customer',
association: 'Customer',
inverse: 'thread'
}
or
reference: {
type: 'Customer',
role: 'customer',
association: 'Customer',
inverse: 'thread'
}
does not work.
Nothing helpful found in
http://docs.sencha.com/extjs/5.0/core_concepts/data_package.html
or
http://docs.sencha.com/extjs/5.0/whats_new/5.0/extjs_upgrade_guide.html
Any of you had any luck with it?
I had exactly the same problem, this link helped me:
http://www.sencha.com/forum/showthread.php?285478-Nested-stores-associated-model-doesn%C2%B4t-contain-any-store
It gave me this:
Ext.define('MyApp.model.Base', {
extend: 'Ext.data.Model',
schema: {
namespace: 'MyApp.model'
}
});
Ext.define('MyApp.model.Application', {
extend: 'MyApp.model.Base',
fields: [
{ name: 'id', type: 'int' },
{ name: 'name', type: 'auto' },
{ name: 'desc', type: 'auto' }
]
});
Ext.define('MyApp.model.ApplicationVersion', {
extend: 'MyApp.model.Base',
fields: [
{ name: 'id', type: 'int' },
{
name: 'appid',
type: 'int',
reference: {
type: 'Application',
role: 'application',
inverse: 'versions'
}
},
{ name: 'version', type: 'auto' }
]
});
And now I have a one-to-many association which works:
> a = Ext.create(MyApp.model.Application, {desc: 'My description'})
constructor {data: Object, session: null, internalId: 30, …}
> a.versions().add({version: '2.5'})
[constructor]
> a.versions().first().application.get('desc')
"My description"

Empty rows appear in grid

I'm trying to create a grid (Ext.grid.Panel) and fill it with data. But something is going wrong so the grid shows empty rows without data.
Model is:
Ext.define('Order', {
extend: 'Ext.data.Model',
fields: [
{
name: 'id',
type: 'int'
},
{
id: 'companyId',
type: 'int'
},
{
id: 'amount',
type: 'int'
},
{
id: 'dealDate',
type: 'date'
},
{
id: 'complete',
type: 'int' //boolean imitation
}
],
idProperty: 'id'
});
Grid & Store code is:
var orders = Ext.create('Ext.data.Store', {
model: 'Order',
proxy: Ext.create('Ext.data.proxy.Ajax', {
url: 'service/orders-data.php?',
reader: Ext.create('Ext.data.reader.Json', {
root: 'orders'
})
}),
sorters: [{
property: 'name',
direction: 'ASC'
}]
});
orders.load();
var ordersGrid = Ext.create('Ext.grid.Panel', {
width: 400,
height: 300,
store: orders,
columns: [
{
text: 'Amount',
dataIndex: 'amount',
width: 120
},
{
text: 'Deal date',
dataIndex: 'dealDate',
width: 120
},
{
text: 'Complete',
dataIndex: 'complete',
width: 120
}
]
});
JSON-response from server is:
{
"orders":[
{
"id":1,
"amount":5000,
"dealDate":"2012-01-05",
"complete":0
},
{
"id":2,
"amount":6850,
"dealDate":"2012-01-07",
"complete":0
},
{
"id":5,
"amount":7400,
"dealDate":"2012-01-09",
"complete":0
}
]
}
Why does the grid display empty rows?
All your model's fields but the first are being declared with 'id' properties where they should instead be using 'name':
{
name: 'id',
type: 'int'
},
{
name: 'companyId',
type: 'int'
},
{
name: 'amount',
type: 'int'
},
{
name: 'dealDate',
type: 'date'
},
{
name: 'complete',
type: 'int' //boolean imitation
}
