ExtJS Issue with boolean data and grid column list filter as well as Ext.Data.Store - extjs

I am using ExtJS 6 (although from what I can tell it applies up to version 7.4 as well) and I have a grid with a booleancolumn xtype. For that boolean column I wanted to use the filter list option. Yes I know there is a boolean filter option however I don't like how it works using a radio button. I wanted to be able to select the Yes or No with checkboxes, however I found that only the option with true as the value worked. Here is my column config:
{
header: 'Active'
, dataIndex: 'inactive'
, xtype: 'booleancolumn'
, trueText: 'No'
, falseText: 'Yes'
, filter:{
type: 'list',
options: [[true,"No"],[false, "Yes"]]
}
}
This didn't work when excluding the 'options' property and letting it get the data from the store either by the way. After looking through the code I discovered that it takes the 'options' config and creates its own Ext.Data.Store using that as the data. See here as a simple example that can be run that will get the same issue:
var teststore = new Ext.data.Store({
fields: [
'id',
'text'
],
data: [[true,"No"],[false, "Yes"]]
});
The problem is that the 'false' boolean value is changed and is replaced with a dynamically created generic id. I discovered the issue lays in the constructor for 'Ext.data.Model' for the following line:
if (!(me.id = id = data[idProperty]) && id !== 0) {
If that line evaluates to true it will replace the id with the generated one. To fix this I just added ' && id !== false' to the end of the if statement and this fixed the issue.
I have not tested this fully, however the logic seems sound and it looks like the same type of issue occurred with the value of '0' hence the ' && id !==0'. Since we are directed here from the sencha forums I wanted to bring this up in case it helps someone.

Since my post already has the answer I will post a better way to do it other than directly changing the Ext code file (whether this is the proper way I may be wrong). Instead, you can create a new js file that will need to be included in your application (you can name it ext-overrides.js). In the new js file you need only type:
Ext.override(Ext.data.Model, {
constructor: function(data, session) {
.....
}
}
You would then copy the constructor function code from your version of the ExtJS code in where the '.....' is (if perchance the constructor function arguments are different you would have to update those as well) and just add the suggested change I made above in the 'question'. A search of the Extjs code for Ext.define('Ext.data.Model' should get you there easily and then just scroll to the constructor function.

Using tablesorter custom parser only for filtering with Checkboxes - working example needed

I am trying to implement filtering my checkbox checked status similar to (or exactly like?) Ivan when he posted "Using tablesorter custom parser only for filtering". I've gone back and forth on custom parsers and text extraction and every permutation from the examples provided in the docs to no avail.
Could someone look at my example posted at
http://jsfiddle.net/5fLr7c4o/14/
and help me get it working?
I'm using the headers and textExtraction function provided in that and other examples:
headers: {
0: {
sorter: 'false',
filter: 'parsed'
}
},
textExtraction: {
0: function (node, table, cellIndex) {
return $(node).find('.MyCheckbox').prop('checked') ? 'True' : 'False';
}
}
To boil it down, I have two buttons. One will filter anything without the checkbox checked, the other resets the filter. The reset is working fine. The filter (in my local file) filters everything. jsfiddle doesn't work at all.
The jsFiddle isn't working because jQuery is being loaded after the plugin. And the framework is set to load jQuery v1.11.0, so jQuery is actually being loaded twice. The second copy overrides the first and the tablesorter is associated to the first copy. Lots of stuff break - here is the demo updated to remove the second copy - but it still doesn't work!
If you use the parser-input-select.js file included in the repository, it has a checkbox parser that updates the cell after changing so the sort updates properly. Anyway, there are four versions of the code, the older ones don't use the mentioned parser. The demo you might be interested in is this one: http://jsfiddle.net/abkNM/6163/ You probably don't need the pager, so just don't include that code:
$(function() {
var $table = $('table').tablesorter({
theme: 'blue',
widgets: ['zebra', 'filter'],
widgetOptions : {
group_checkbox: [ "checked", "unchecked" ]
},
headers: {
0: { sorter: 'checkbox' }
}
})
// HEADER CELL Checkbox - toggles state of visible checkboxes
// make sure to include the "parser-input-select.js" file
// it contains the most up-to-date checkbox parser
.on('change', 'thead input[type="checkbox"]', function(){
var checkboxColumn = 0,
onlyVisible = true,
$this = $(this),
isChecked = this.checked;
$table
.children('tbody')
.children( 'tr' + ( onlyVisible ? ':visible' : '' ) )
.children(':nth-child(' + ( checkboxColumn + 1 ) + ')')
.find('input')
.prop('checked', isChecked)
.trigger('update');
});
});
Make sure to modify the checkboxColumn & onlyVisible variables as desired.
Update: There was an error in the parser code that was just fixed, it is currently available in the master branch only (linked in my answer). Otherwise you could just enter unchecked or checked" (checked with a quote for an exact match) to filter the checkboxes.
These filter names (checkbox states) are set by the group_checkbox option, which I just added to my answer.

what is a correct way to pass extraParams when updating grid?

A grid has editable rows, connected to a store which has a proxy.
It uses the api e.g.
proxy: {
type: 'ajax',
api: {
create: 'dm/acct/new.php',
read: 'dm/acct/read.php',
update: 'dm/acct/update.php',
destroy: 'dm/acct/rm.php'
},
extraParams: {
sess: 2345
},
If I add extraParms to the store's proxy e.g. {abc:123} as shown above, when I come to edit a field on a grid, that detail is accompanied by the record at the server with the value defined. I can inspect it in the read.php.
However, for testing, I tried replacing abc with an application level var, e.g.
{abc:RPA.app.A_GLOBAL_VAR}
results in
Uncaught TypeError: Cannot read property 'A_GLOBAL_VAR' of undefined - this surprised me since the var is declared at the Application level and I thought would be scoped and available. This error causes the application to fail to run at all.
I have got it working but I don't like my approach because I think it is using the wrong event and I have not been able to spot a more suitable one.
On the grid' cell dblClick event I have:
var sto = Ext.getCmp('acc_grid').getStore();
var proxy= sto.getProxy();
proxy.setExtraParam('abc', somevar );
I definitely get the value of abc:somvar server-side - so does what I want. I just think it is bad design/wrong event and wondered if there is a better way of attaching the extra param to the record when the update on an editable grid? I have looked at other examples but not stumbled across one that I have been able to relate to.
Many thanks
Kevin
Listen to the CellEditor plugin edit event rather than the cell dblclick...
http://docs.sencha.com/extjs/4.2.2/#!/api/Ext.grid.plugin.CellEditing
When you set your cell editing plugin...
plugins: [
Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1,
listeners:{
edit:function(){ doSomething }
}
})
],

Extjs 4.0.7, Editor Grid - how to get updated cell value?

I need to get(retrieve) updated cell value in controller. (MVC)
So I tried this,
var modified = this.getItemGrid().getStore().getUpdatedRecords();
console.log(modified); // return [] empty array
var modified = this.getItemList_Store().getUpdatedRecords();
console.log(modified); // return [] empty array
but always it returns empty array even I updated some cell value.
anybody know what I am doing wrong?
Here is my part of view code,
Ext.define("App.view.orders.ItemList_view", {
extend: "Ext.grid.Panel",
alias: "widget.itemList_view",
plugins: [
Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1
})
],
initComponent: function () {
this.store = "ItemList_store";
this.columns = [
{
xtype: 'checkcolumn', text: "Ship", width: 50, dataIndex: "DR"
},
{ header: "test", width: 100, dataIndex: "test",
editor: {
xtype : 'textfield'
}
}
];
this.selModel = Ext.create("Ext.selection.CheckboxModel");
//this.selModel = Ext.create("Ext.selection.CellModel"); // It does not works either.
this.callParent(arguments);
},
.
.

Thank you!
[EDIT]
Thank you very much for your answer! I have some more question about editor grid.
Its much different from Ext3. so I'm very confusing now :(
Q1. How to collect edited record data (once click button)?
the event fired once the grid cell be changed.
but I want collect edited grid record once I click the 'Update edited cell' button, and I want to update all together at the once.
In Ext3, I did like this,
(button) click : function(){
var modified = mygridStore.getModifiedRecords();
var recordsToSend = [];
Ext.each(modified, function(record){
recordsToSend.push(record.data);
});
var grid = Ext.getCmp('grid');
grid.el.mask('Updating','x-mask-loading');
grid.stopEditing();
recordsToSend = Ext.encode(recordsToSend);
Ext.Ajax.request({
url : '/test/test',
params : {
data : recordsToSend
},
success : function(response){
grid.el.unmask();
alert(response.responseText);
mygridStore.commitChanges();
},
failure : function(response){
mygridStore.rejectChanges();
}
});
}
How can I change the code for Extjs4 ?
Q2. I don't know still how to find out for changed checkcolumn.
I tried this, but I does not work for checkcolumn (of cause I tested after change checkbox)
// grid coumn
{
xtype: 'checkcolumn', header: "My Check Column", width: 50, dataIndex: "CH"
}
-
// in control
'myGrid': {
validateedit: function (plugin, edit) {
console.log(edit);
},
checkchange: function (plugin, edit) {
console.log(edit);
console.log(edit.value);
}
}
Q3. When I click the cell to edit, the show some HTML tag in -_-;;
I really appreciate for your help. and thank you very much for your valuable time!
The editors (cell editors or row editors) do not commit their values to the store until you complete the edit - which means pressing ENTER or blurring the active cell editor by clicking elsewhere on the page, or clicking the save button on the row editor form .
If your purpose for reading the updated value in your editor is to perform some kind of validation I would suggest simply listening to the validateedit event in your grid's controller, as described here.
The second argument that this event passes to your handler contains a lot of data about the edit that you can then perform validation with. If the edit doesn't pass your validation you can return false from your handler and the value in the celleditor will revert to it's original value. The validateedit event gets fired from the editor grid itself so you would add an event handler in your controller for it like this:
Ext.define('MyApp.controller.MyController', {
init: function() {
this.control({
'mygridpanel': {
validateedit: function(plugin, edit) {
// silly validation function
if (edit.value != 'A Valid Value') {
return false;
}
},
},
});
},
});
But you should check out the link above to see all the different objects available in that second argument I named edit.
The validateedit event is fired right before the record is committed into the store - after the user has already clicked ENTER or blurred the editor, i.e., while the editor is closing.
If you are trying to get the celleditor's value before it starts to close, for some reason other than validation for example, you could get the active celleditor's value like this:
// myGrid is a reference to your Ext.grid.Panel instance
if (myGrid.editingPlugin.editing) {
var value = myGrid.editingPlugin.getActiveEditor().field.value
console.log('value: ' + value);
}
If there is no active editor then myGrid.editingPlugin.getActiveEditor().field would throw an error, that's why I wrapped a conditional around it.
One other point I should make, for validation in editor grids, I found that it is easiest to just put a validator config in the grid column's editor definition. That will give you all the handy validation CSS while the user is setting the field's value and alert him if there is a problem with the value before he tries to save it.
To get an idea of what I mean, try entering letters in the date column of this example. Mouse over the editor cell and you will get the error message.
EDIT
It seems I misunderstood you original question, I'll break down my answers to your questions above though,
Question 1
Once you have completed an edit (clicked ENTER or ), your call to mygridStore.getModifiedRecords() should be working fine because the record will have been committed to the store. I see that it was not working, I will cover that in a moment.
I should point out that ExtJS4 has a store.sync() method as covered here.
Instead of extracting the modified records from the store, encoding them, manually doing an ajax request to save them to the server and then manually committing them you can call this sync method and it will take care of all of these actions for you.
If you have different URLs to handle the different create, read, update, destroy operations fired off by your store's load and sync methods, you can use the store's proxy api config to map your URLs to these operations as covered here. Or you can set-up your server side controller to be able to differentiate between your store's load request (read operations default to HTTP GET) and it's sync requests (create, update and delete operations default as HTTP POST).
There could be many different ways to go about doing this on the server side, the way I usually do it is to have one SQL stored procedure for GET requests and one for POST requests for any given store. I include the store name as an extra param and then my server side controller runs the appropriate stored procedure based on whether it is a GET or a POST request.
Question 2
Cell editing doesn't support checkcolumn edits. You have to make a different handler to listen to changes on that, something like this:
checkchange: function (column, rowIndex, checked) {
var record = store.getAt(rowIndex),
state = checked ? 'checked' : 'unchecked'
console.log('The record:');
console.log(record)
console.log('Column: ' + column.dataIndex);
console.log('was just ' + state)
}
Your call to mygridStore.getModifiedRecords() should be able to pick up the check changes also however, they get committed to the grid's store right away after being checked. store.sync() would also pick up changes to checkcolumn.
Question 3
I can't completely tell what is causing that problem but it may be something strange going on with your validateedit event, your handler should be returning true or false.
As I said earlier, I misunderstood the reason you originally asked this question. I thought you were trying to do some kind of validation while an edit was in progress. Now I understand that you are trying to get all of the modified records from the store after all the editing is completed in order to save them to the database, I was thrown off because in ExtJS 4 a store is usually saved to the database with the sync method as I mentioned.
In other words, you don't need the validateedit event or checkchange event to get a list of modified records.
The actual problem you are having might be trouble with the store's getter methods (getModifiedRecords, getUpdatedRecords) in some 4.07 versions, take a look at this post and this one.
So with all that said, the best advice I can give you is 1) try out the stores sync method for saving modified data to the database and 2) upgrade to ExtJS 4.1, there were a lot of bugs that were straightened out between 4.07 and 4.1 which you should be able to take advantage of, I cut out about 75% of the overrides I was using to make things work when I switched over to 4.1.
EditedGrid.plugins[0].completeEdit();
This will make the active changes commit and call edit event also.
listeners: {
validateedit: function (editor, e) {
//console.log(editor);
var oldVal = editor.originalValue;
var newVal = editor.value;
}
}

extjs store fail

ExtJS Model fields have mapping option.
fields: [
{name: 'brandId', mapping:'brand.id', type: 'int'},
{name: 'brandName', mapping:'brand.name', type: 'string'},
The problem is: if the response from server does not contain some field(brand field in my example) and mapping from inner fields is defined, Ext Store silently fails to load any records.
Does anybody have problems with this? Is it some kind of a bug?
UPDATE
To make it clear: suppose I have ten fields in my model. Response from server has nine fields, one is missing. If there is no nested mapping for this field (mapping:'x.y.z') everything is OK - store loads record, the field is empty. But if this field has to be loaded from some nested field and has mapping option - store fails to load ANYTHING.
UPDATE 2
I have found the code, that causes problems. The fact is: when Ext tries to load some field from Json it performs a check like this
(source["id"] === undefined) ? __field0.defaultValue : source["id"]
But when field has mapping option(mapping 'brand.id') Reader does it this way
(source.brand.id === undefined) ? __field20.defaultValue : source.brand.id
which causes error if source has no brand field.
In case you have same problems as I: you can fix it by overloading Ext.data.reader.Json's method createFieldAccessExpression
I agree that Ext should only fail to load that field, not the entire record. One option that isn't great, but should work, is instead use a mapping function:
{
name: 'brandId',
mapping: function(data, record) {
return data.brand && data.brand.id;
}
}
I could have the arguments wrong (I figured out that this feature existed by looking at the source code), so maybe put a breakpoint in there to see what's available if it doesn't work like this.
I think you're misinterpret mapping and nesting paradigms: these are not interchangeable.
If you define nesting in your data, the result MUST have the corresponding field.

Custom Edit control inside a ExtJS Editor grid

Got an issue, and need your advices
I just started writing an editor grid. (I will actually use this grid as a search filter editor, i.e. columns with criteria name, operators and values).
Now, for the value field, I want to have different edit controls for different rows. For instance, when a criteria type is string I want to display a text box, when it's date time, I want a datetime editor.
So the fact is, I need to control the "edit control creation/display" just before editing starts. and it should be different among rows. Unlike the examples I found which are fixed for the columns.
In order to implement this, can you guys please suggest the steps I need to do? I can probably figure out it if one of you can direct me a way.
Thanks and best regards
Actually you can easily accomplish this by dynamically returning different editors and renders depending on the column you're in. In your ColumnModel object you can define something like this below. Note that i'm getting a type property of each record to determine its type. I have an object containing all my different types of editors, and the same for renderers, and then based on the the type i dish out a different editor or renderer for that cell.
editors: { 'default': {xtype:'textfield'},
texttype: {xtype:'textfield'},
numbertype: {xtype:'numberfield'},
combotype: {xtype:'combo'}....... etc. }
getCellEditor: function(colIndex, rowIndex) {
var store = Ext.getCmp('mygrid').getStore();
var field = this.getDataIndex(colIndex);
var rec = store.getAt(rowIndex);
var type = rec.get('type');
if (type in this.editors) {
return this.editors[type];
} else {
return this.editors['default'];
}
},
In the configuration section of your editorgrid, you will need to define your custom editors:
{
xtype: 'editorgrid',
id : 'mygridID',
stripeRows: true,
...
...
,customEditors : {
//configs go here or pre-define the configs prior to this
'columnName1' : new Ext.grid.GridEditor(new Ext.form.Combobox(configObject)),
//configs go here or pre-define the configs prior to this
'columnName7' : new Ext.grid.GridEditor(new Ext.form.CheckBox(configObject))
}
}
use this grid config - in order to select whole rows:
selType: 'rowmodel'
