I'm trying to render a table view with four columns, 'name', 'birthday', 'gender', 'married', but
a) they columns aren't showing up at all
b) I'm not even sure if I am passing them correctly, because when I console.log table.options the columns property is rendered as "empty":
Object {columns: Array[0], emptyContent: "no entries", onItemClick: function, sortable: false, onSort: null}
I've tried this:
var table = new Backbone.UI.TableView({
model: people,
columns: [
{ title: "Name", content: 'name' },
{ title: "Gender", content: "gender" } },
{ title: "Birthday", content: "birthday" } },
{ title: "Married", content: "married" } }
]
});
And this:
var table = new Backbone.UI.TableView({
model: people,
options: {
columns: [
{ title: "Name", content: 'name' },
{ title: "Gender", content: "gender" },
{ title: "Birthday", content: "birthday" },
{ title: "Married", content: "married" }
]
}
});
The source code change is adding the options as mu is too short said. Change the initialize method of the Backbone.UI.TableView object to be the following within the source code:
initialize : function(options) { //add parameter
Backbone.UI.CollectionView.prototype.initialize.call(this, arguments);
$(this.el).addClass('table_view');
this._sortState = {reverse : true};
this.options = _.extend({}, this.options, options); //Add this line
}
I'm sure there might be a better place to put this but I'm just going through tutorials to learn some advanced backbone stuff considering the documentation does not match the current version I would shy away from using the library in production as of right now. Hopefully it is fixed in the future.

Given is following data structure
const list = [
{
title: 'Section One',
data: [
{
title: 'Ay',
},
{
title: 'Bx',
},
{
title: 'By',
},
{
title: 'Cx',
},
],
},
{
title: 'Section Two',
data: [
{
title: 'Ay',
},
{
title: 'Bx',
},
{
title: 'By',
},
{
title: 'Cx',
},
],
},
];
What i want to do ist to filter this list based on title property in the data array of each object.
An example would be to have the list where the title property of the childs starts with "B", so the list will look like that:
const filteredList = [
{
title: 'Section One',
data: [
{
title: 'Bx',
},
{
title: 'By',
}
],
},
{
title: 'Section Two',
data: [
{
title: 'Bx',
},
{
title: 'By',
}
],
},
];
What i tried so far was something like that:
const items = list.filter(item =>
item.data.find(x => x.title.startsWith('A')),
);
or
const filtered = list.filter(childList => {
childList.data.filter(item => {
if (item.title.startsWith('B')) {
return item;
}
return childList;
});
});
But i think i am missing a major point here, maybe some of you could give me a tip or hint what i am doing wrong
Best regards
Your issue is that you're doing .filter() on list. This will either keep or remove your objects in list. However, in your case, you want to keep all objects in list and instead map them to a new object. To do this you can use .map(). This way you can map your objects in your list array to new objects which contain filtered data arrays. Here's an example of how you might do it:
const list=[{title:"Section One",data:[{title:"Ay"},{title:"Bx"},{title:"By"},{title:"Cx"}]},{title:"Section Two",data:[{title:"Ay"},{title:"Bx"},{title:"By"},{title:"Cx"}]}];
const filterByTitle = (search, arr) =>
arr.map(
({data, ...rest}) => ({
...rest,
data: data.filter(({title}) => title.startsWith(search))
})
);
console.log(filterByTitle('B', list));
I use kendo ui grid with angular. I want the grid to be updated with every change in the array (of any property). Meaning, if my data is:
this.rowData = [{ id: "1", name: "A", age: "16" }, { id: "2", name: "B", age: "42" }];
and the age is changed from 16 to 17 I want the grid to be updated automatically.
I understand that I can use ObservableArray and when updating the observable the grid will be updated but I don't want the entire application to know the observable. I want to be able to update the original rowData and affect the grid. Any suggestions of how I do that?
I thought that adding a template to a row or a specific column with angular binding will help but it didn't, here is an example of it:
function Controller(GridConstants) {
this.rowData = [{ id: "1", name: "A", age: "16" }, { id: "2", name: "B", age: "42" }];
this.gridDataSource = new kendo.data.DataSource({
data: new kendo.data.ObservableArray(this.rowData),
schema: {
model: { id: "id" }
}
});
this.gridOptions = {
dataSource: this.gridDataSource,
selectable: "row",
columns: [
{
field: "name",
title: "Name"
},
{
field: "age",
title: "Age",
template: "<label>{{dataItem.age}}</label>"
}
],
selectable: "single"
};
}
You can try ng-bind instead:
template: "<label ng-bind='dataItem.age'></label>"
var rowDataObservable = new kendo.data.ObservableArray(this.rowData);
...
data: rowDataObservable,
...
//and you need work with rowDataObservable, this will work
rowDataObservable[0].age = 17;
demoAlerts({
itemstatus: [
{
item: "1",
name: "apple",
type: "fruit"
},
{
item: "2",
name: "pine",
type: "fruit"
}
],
deliverystatus: [
{
name: "james",
status: "yes"
},
{
name: "thomas",
status: "no"
},
]
});
I have two array (itemstatus and deliverystatus), I need to create the model for this store. what I tried is
ParentModel:
Ext.define('test.model.ParentModel', {
extend: 'Ext.data.Model',
requires:['test.model.ItemModel','test.model.DeliveryModel'],
autoLoad: true,
config : {
fields : [ 'itemstatus', {
name : 'demostatuslist',
model : 'demoAlerts.model.ItemModel',
mapping : 'itemstatus'
},
'portalstatus', {
name : 'deliverystatus',
model : 'test.model.DeliveryModel',
mapping : ' deliverystatus'
}]
}
});
ItemModel
Ext.define('demoAlerts.model.ItemModel', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'item', type: 'string' },
{ name: 'name', type: 'string' },
{ name: 'type', type: 'string' }
]
}
});
DeliveryModel
Ext.define('demoAlerts.model.DeliveryModel', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'name', type: 'string' },
{ name: 'status', type: 'string' },
]
}
});
Whether i properly configured the model. I am receiving the store as empty
Use Associations :) http://docs.sencha.com/touch/2.3.1/#!/api/Ext.data.association.Association
In this case I would have a Model with 2 hasMany associations like this:
Ext.define('demoAlerts.model.ContainerModel', {
extend : 'Ext.data.Model',
requires : [
'demoAlerts.model.DeliveryModel',
'demoAlerts.model.ItemModel'
],
config : {
associations: [
{
type : 'hasMany',
model : 'demoAlerts.model.DeliveryModel',
associationKey : 'deliveryStatus',
name : 'deliveryStatus',
autoLoad : true // this is very important
},
{
type : 'hasMany',
model : 'demoAlerts.model.ItemModel',
associationKey : 'itemStatus',
name : 'itemStatus',
autoLoad : true // this is very important
}
]
}
});
Then use a store SomeStore binded to ContainerModel.
IMPORTANT Each record in SomeStore will have deliveryStatusStore and itemStatusStore AUTOGENERATED.
Read about associations.
Neither http://docs.sencha.com/touch/2.3.1/#!/api/Ext.data.Field
nor http://docs.sencha.com/extjs/5.0/apidocs/#!/api/Ext.data.field.Field
knows a valid config option "model" for a field.
As far as I know, there is no such thing as a "Parent Model" available in ExtJS or Sencha Touch.
As far as I know, there is no possibility to have two stores in one.
You can load two (or more) stores using only one call to the server like in my following example:
firststore.on('load',function() {
secondstore.loadRawData(firststore.getProxy().getReader().rawData);
});
firststore.load()
Where you would give firststore the server url and the root of the data that goes into the first store, and secondstore will have the root of the data that goes into the second store.
Please be aware that the second store won't be filled if zero records go into the first store, and choose your stores appropriately.
If any of your stores can be the only empty store, perhaps you will have to get the rawdata via Ext.data.Request and load it into all stores afterwards.
I have a grid, inside of some column of which I have created a combobox editing UI, using columns.editor function.
My goal is every time a user selects some value from the combobox -while populating a newly created grid record-, this value to be
removed from the list options of a next record's combobox.
One of the things i've tried is shown below:
function equipmentDropDownEditor(container, options) {
var equipmentComboBox = $('<input id="equipmentDropDownEditor" required data-text-field="name" data-value-field="name" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoComboBox({
autoBind: false,
dataSource: equipmentTypesDS,
dataBound: function(e) {
var equipmentData = e.sender.dataSource.data();
if(currentlyInsertedEquipmentTypes.length > 0){
for(var i=0;i<currentlyInsertedEquipmentTypes.length;i++){
$.each( equipmentData, function( index, selectedEquipmentData ) {
if (selectedEquipmentData.name == currentlyInsertedEquipmentTypes[i]){
var dataItem = e.sender.dataSource.at(index);
console.log("dataItem: " + dataItem.name + " is being removed");
e.sender.dataSource.remove(dataItem);
}
});
}
}
}
});
}
I've created a global array variable named "currentlyInsertedEquipmentTypes" inside of which I hold all the user's already selected values
(for example if the user has created 2 records inside the grid and has selected "laptop" option in the combobox of the first and "workstation" option
in the combobox of the second --> currentlyInsertedEquipmentTypes = ["laptop", "workstation"] ).
Inside the combobox dataBound event I check whether the user has already selected values (currentlyInsertedEquipmentTypes.length>0)
and if he has, I locate the corresponding object inside the bound dataSource and I remove it, so that it wont be available in the next record's combobox list.
This is where the whole thing crashes even though the data item removal takes place.
Am i missing something that i should do after the data item removal? Should i rebind the datasource to the combobox in some way?
Any help would be much appreciated.
[EDIT]
---- The combobox datasource code
var equipmentTypesDS= new kendo.data.DataSource({
transport: {
read: {
url: "api/equipment_types",
type: "GET",
data: {
//"equipment_category": 1
},
dataType: "json"
}
},
schema: {
data: "data",
total: "total"
}
});
--- the kendo grid code:
$("#popup_equipment").kendoGrid({
dataSource: {
schema:{
model:{
id: "equipment_type_id",
fields:{
equipment_type_id: { editable: false },
name: { }, //validation: {required: true}, defaultValue: "LAPTOP",
items:{ type: "number", defaultValue:1, validation: { required: true, min: 1} }
}
}
}
},
toolbar: ["create"],
columns: [
{ field: "name", title: "εξοπλισμός", width: "300px", editor: equipmentDropDownEditor, template: "#=name#" },
{ field: "items", title:"πλήθος", width: "80px"},
{ command: ["destroy"], title: " ", width: "100px" }
],
//editable: "inline",//true,
editable:{confirmation: false},
scrollable: false,
selectable: false
});
[EDIT 2]
$("#popup_equipment").kendoGrid({
dataSource: {
schema:{
model:{
id: "equipment_type_id",
fields:{
equipment_type_id: { editable: false },
name: { }, //validation: {required: true}, defaultValue: "LAPTOP",
items:{ type: "number", defaultValue:1, validation: { required: true, min: 1} }
}
}
}
},
toolbar: ["create"],
columns: [
{ field: "name", title: "εξοπλισμός", width: "60%", editor: equipmentDropDownEditor, template: "#=name#" },
{ field: "items", title:"πλήθος", width: "20%"},
{ command: ["destroy"], title: " ", width: "20%" }
],
editable:{confirmation: false},
scrollable: false,
selectable: false,
save: function(e){
console.log("GRID SAVE EVENT! ", e);
var equipment_name = e.values.name;
equipmentTypesDS.get(equipment_name).used = true;
console.log("equipmentTypesDS", equipmentTypesDS);
console.log("END OF GRID SAVE EVENT!");
}
});
function equipmentDropDownEditor(container, options) {
var equipmentComboBox = $('<input id="equipmentDropDownEditor" required data-text-field="name" data-value-field="name" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoComboBox({
autoBind: false,
dataSource: equipmentTypesDS,
});
}
var equipmentTypesDS= new kendo.data.DataSource({
transport: {
read: {
url: "api/equipment_types",
type: "GET",
data: {
//"equipment_category": 1
},
dataType: "json"
}
},
schema: {
data: "data",
total: "total",
model:{
id: "name"
}
},
filter: { field: "used", operator: "neq", value: true }
});
I would suggest a different approach. Instead of removing the element filter it out.
Example: I define a DataSource with a list of Cities (your Inserted Equipment) as follow:
var cityDS = new kendo.data.DataSource ({
data : [
{ City : "Seattle", used : false },
{ City : "Tacoma", used : false },
{ City : "Kirkland", used : false },
{ City : "Redmond", used : false },
{ City : "London", used : false },
{ City : "Philadelphia", used : false },
{ City : "New York", used : false },
{ City : "Boston", used : false }
],
schema : {
model : {
id : "City"
}
},
filter: { field: "used", operator: "eq", value: false }
});
As you can see I added a field called used that simply says if that City is already used or not. And I set it as id of this DataSource. In addition, I set a filter saying that I only want those where used id equal (eq) to false.
The editor function is pretty much yours:
function cityDropDownEditor(container, options) {
var equipmentComboBox = $('<input required data-text-field="City" data-value-field="City" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoComboBox({
autoBind: false,
dataSource: cityDS
});
}
but with no dataBound or any other event handler.
Finally in the Grid when I save a record, I filter that city from the list. Something like:
var grid = $("#grid").kendoGrid({
dataSource: ds,
editable : "popup",
pageable : true,
toolbar: [ "create" ],
columns :
[
{ field: "FirstName", width: 90, title: "First Name" },
{ field: "LastName", width: 200, title: "Last Name" },
{ field: "City", width: 200, editor : cityDropDownEditor }
],
save : function(e) {
console.log("e", e);
var city = e.model.City;
cityDS.get(city).used = true;
}
}).data("kendoGrid");
This might work if you start the Grid with no elements otherwise you would have to conveniently initialize the used field. It might require some additional code dealing with cases as changing the City but from your description, doesn't seem to be the case.
You can see this running here : http://jsfiddle.net/OnaBai/ZH4aD/
Is there a way to make an ExtJS4 PropertyGrid (Ext.grid.property.Grid) non-editable?
There is no "editable" or "readonly" config option AFAICS.
Another solution is to add a listener, that prevents starting the editing component:
listeners: {
'beforeedit': {
fn: function () {
return false;
}
}
}
The problem with this solution is, that one can not mark a cell to copy (Ctrl+C) the contents.
Use the sourceConfig to set the editor to a Ext.form.DisplayField:
Ext.create('Ext.grid.PropertyGrid', {
sourceConfig: {
field1: {
displayName: 'Editable Field'
},
field2: {
displayName: 'Readonly Field',
editor: Ext.create('Ext.form.DisplayField')
}
},
source: {
field1: "Some property",
field2: "Some other property",
}
});
One more decision, but don't allow to select text thereafter: myGrid.findPlugin('cellediting').disable();
One solution is to prevent the selection of any cell:
var myPropertyGrid = Ext.create('Ext.grid.property.Grid', { ... });
myPropertyGrid.getSelectionModel().setLocked(true);
Ext.define('MyPropertyGrid', {
extend: 'Ext.grid.property.Grid',
xtype: 'mypropertygrid',
source: {
field1: 'value of field1',
field2: 'value of field2'
},
sourceConfig: {
field1: {
editor: {disabled: true}
},
field2: {
editor: {disabled: true}
}
}
});
I test it on Extjs 6.0.
