I've created Ext.grid.Panel and now I need to make a summary with data calculated on server. And I have no grouping in that grid.
In feature ftype: 'summary' there is no such property like 'remoteRoot'.
Is there any opportunity to create this summary withou grouping?
You have to extend / override class. This is an example based on AbstractSummary.js and should be optimised.
// usage in grid:
{
ftype : 'summary',
remoteRoot : 'summary'
}
//response from server
{
data : [] // our standard data
summary : {
summaryField : 123123
}
}
// our class
Ext.define('w3desApp.grid.feature.Summary', {
override : 'Ext.grid.feature.Summary',
getSummary: function(store, type, field, group) {
var reader = store.proxy.reader;
if (this.remoteRoot && reader.rawData) {
// reset reader root and rebuild extractors to extract summaries data
root = reader.root;
reader.root = this.remoteRoot;
reader.buildExtractors(true);
summaryRow = reader.getRoot(reader.rawData);
// restore initial reader configuration
reader.root = root;
reader.buildExtractors(true);
if (typeof summaryRow[field] != 'undefined') {
return summaryRow[field];
}
return '';
}
return this.callParent(arguments);
}
});

I'm trying to create a CloudWatch alarm that will cycle through instances defined in data.tf and for each on of these to cycle through the volume id's
data.tf
data "aws_instances" "instance_cloudwatch" {
instance_tags = {
Type = var.type
}
}
data "aws_ebs_volumes" "cw_volumes" {
tags = {
Name = var.name
}
}
data "aws_ebs_volume" "cw_volume" {
for_each = toset(data.aws_ebs_volumes.cw_volumes.ids)
filter {
name = "volume-id"
values = [each.value]
}
}
In the resource I created
locals {
vol_map = {
for pair in setproduct(data.aws_instances.instance_cloudwatch.ids,data.aws_ebs_volume.cw_volume.*.id) : "${pair[0]}-${pair[1]}" => {
id = pair[0]
vol = pair[1]
}
}
}
And then I try to use these pairs in the alarm dimensions
resource "aws_cloudwatch_metric_alarm" "some_alarm" {
for_each = local.vol_map
...
dimensions = {
InstanceId = each.value.id
VolumeId = each.value.vol
}
When I run terraform apply I get this error
Error: Unsupported attribute
for pair in setproduct(data.aws_instances.instance_cloudwatch.ids,data.aws_ebs_volume.cw_volume..id) : "${pair[0]}-${pair[1]}" => {*
This object does not have an attribute named "id" I tried volume_id and got the same error
The issue is that you can't use the .*. syntax (in data.aws_instances.instance_cloudwatch.ids,data.aws_ebs_volume.cw_volume.*.id) on a resource that you created with for_each. The .*. syntax only works when you use count. This is because it only works with arrays/lists, and for_each creates a map.
Try values(data.aws_instances.instance_cloudwatch.ids,data.aws_ebs_volume.cw_volume).*.id. This will get the data.aws_ebs_volume.cw_volume values as a list instead of a map, so you can then use .*. on them.
I have a model with default values. My app gets the data from user through EditTexts and add them to Firebase Firestore. I hava an addData function (in AddAnalyzeActivity) and savefunction (in AddAnalyzeViewModel) for this operation. I'm getting EditText entries in AddAnalyzeActivity and adding them to my model but on this step ı want to add document id to my model but I can't access the documentIds properly in AddAnalyzeActivity. I can only access them with a forEach method when I try to retrieving the mentioned data with retrieveData function (in PairDetailVM) from Firestore but If I try to add document Ids in retrieveData method it only adds default value of documentId.
What I tried to:
Using #DocumentId annotation in my model.
Setting null default value of documentId in my model.
Getting a list of all documents' ids but can't match them with actual items.
Here is the screenShot for logic:
AnalyzeModel:
data class AnalyzeModel(
var concept: String?="",
var reason: String?="",
var result: String?="",
var rrRatio: Double?=0.0,
var tarih: Timestamp=Timestamp.now(),
var tradingViewUrl: String="",
var id : String="")
addData :
fun addData(view: View) {
val tarih = com.google.firebase.Timestamp.now()
val rr = rrText.text.toString()
var doubleRR = rr.toDoubleOrNull()
if (doubleRR == null) { doubleRR = 0.0 }
val analyzeDTO = AnalyzeModel(
conceptText.text.toString(),
reasonForText.text.toString(),
resultAddingText.text.toString(),
doubleRR,
tarih,
chartImage.text.toString()
)
viewModel.save(analyzeDTO)
val intent = Intent(this, PairDetailActivity::class.java)
startActivity(intent)
finish()
}
save :
fun save(data: AnalyzeModel) {
database.collection(dbCollection!!).document("Specified").collection("Pairs")
.document(chosenPair!!)
.collection("Analysis")
.add(data)
.addOnFailureListener { exception ->
exception.printStackTrace()
Toast.makeText(getApplication(), exception.localizedMessage, Toast.LENGTH_LONG).show()
}
}
retrieveData:
private fun retrieveData() {
val docRef = collectionRef.orderBy("tarih", Query.Direction.DESCENDING)
docRef.addSnapshotListener { value, error ->
try {
if (value != null && !value.isEmpty) {
val allAnalysis= ArrayList<AnalyzeModel>()
val documents = value.documents
documents.forEach {
val analyze = it.toObject(AnalyzeModel::class.java)
if (analyze!=null){
allAnalysis.add(analyze)
}
}
list.value = allAnalysis
} else if (error != null) {
Toast.makeText(Application(), error.localizedMessage, Toast.LENGTH_LONG).show()
}
} catch (e: Exception) {
e.printStackTrace()
}
}
}
If you want to save the document ID into the document itself, consider separating the creation of the new DocumentReference from writing to it, by using set instead of add.
fun save(data: AnalyzeModel) {
val newRef = database.collection(dbCollection!!).document("Specified").collection("Pairs")
.document(chosenPair!!)
.collection("Analysis")
.document() // 👈 generates a new reference with a unique ID
data.id = newRef.id // 👈 set the ID into your object
newRef.set(data) // 👈 writes the data to the new reference
.addOnFailureListener { exception ->
exception.printStackTrace()
Toast.makeText(getApplication(), exception.localizedMessage, Toast.LENGTH_LONG).show()
}
}
Also see the second snippet in the documentation on adding a document
I was taking a look at this :
tornadofx
and tried to expand on it with database connection and little more options, (not all of them make sense, but its just playing in a sandbox).
Even though table can be directly edited and the data will persist in database, i did try to do edit through text fields too. actual table editing would happen through different view and not table itself, as i said its just example.
Database used is Jetbrains Exposed.
object Categories : IntIdTable() {
val name = varchar("name", 64).uniqueIndex()
val description = varchar("description", 128)
}
class Category(id: EntityID<Int>) : IntEntity(id) {
companion object : IntEntityClass<Category>(Categories)
var name by Categories.name
var description by Categories.description
override fun toString(): String {
return "Category(name=\"$name\", description=\"$description\")"
}
}
now controller looks something like this, functions are just rudimentary and picked as an example.
typealias ModelToDirtyState = Map.Entry<CategoryModel, TableColumnDirtyState<CategoryModel>>
class CategoryModel() : ItemViewModel<Category>() {
val name: SimpleStringProperty = bind(Category::name)
val description: SimpleStringProperty = bind(Category::description)
}
class DBController : Controller() {
val categories: ObservableList<CategoryModel> by lazy {
transaction {
SchemaUtils.create(Categories)
Category.all().map {
CategoryModel().apply {
item = it
}
}.observable()
}
}
init {
Database.connect(
"jdbc:mysql://localhost:3306/test", driver = "com.mysql.cj.jdbc.Driver",
user = "test", password = "test"
)
TransactionManager.manager.defaultIsolationLevel = Connection.TRANSACTION_SERIALIZABLE
}
fun deleteCategory(model: CategoryModel) {
runAsync {
transaction {
model.item.delete()
}
}
categories.remove(model)
}
fun updateCategory(model: CategoryModel) {
transaction {
Categories.update {
model.commit()
}
}
}
fun commitDirty(modelDirtyMappings: Sequence<ModelToDirtyState>) {
transaction {
modelDirtyMappings.filter { it.value.isDirty }.forEach {
it.key.commit()
println(it.key)// commit value to database
it.value.commit() // clear dirty state
}
}
}
Just to quickly comment on controller, delete method works as "intended" however the update one does not, it does not work in sense that after using delete item is remove both from database and tableview(underlying list) itself, and when i do update its not, now i know the reason, i call remove manually on both database and list, now for update perhaps i could do change listener, or maybe tornadofx can do this for me, i just cant set it up to do it. Following code will make things clearer i think.
class CategoryEditor : View("Categories") {
val categoryModel: CategoryModel by inject()
val dbController: DBController by inject()
var categoryTable: TableViewEditModel<CategoryModel> by singleAssign()
var categories: ObservableList<CategoryModel> by singleAssign()
override val root = borderpane {
categories = dbController.categories
center = vbox {
buttonbar {
button("Commit") {
action {
dbController.commitDirty(categoryTable.items.asSequence())
}
}
button("Roll;back") {
action {
categoryTable.rollback()
}
}
// This model only works when i use categorytable.tableview.selected item, if i use categoryModel, list gets updated but not the view itself
// Question #1 how to use just categoryModel variable without need to use categorytable.tableview.selecteditem
button("Delete ") {
action {
val model = categoryTable.tableView.selectedItem
when (model) {
null -> return#action
else -> dbController.deleteCategory(model)
}
}
}
//And here no matter what i did i could not make the view update
button("Update") {
action {
when (categoryModel) {
null -> return#action
else -> dbController.updateCategory(categoryModel)
}
categoryTable.tableView.refresh()
}
}
}
tableview<CategoryModel> {
categoryTable = editModel
items = categories
enableCellEditing()
enableDirtyTracking()
onUserSelect() {
//open a dialog
}
//DOES WORK
categoryModel.rebindOnChange(this) { selectedItem ->
item = selectedItem?.item ?: CategoryModel().item
}
// Question #2. why bindSelected does not work, and i have to do it like above
//DOES NOT WORK
// bindSelected(categoryModel)
//
column("Name", CategoryModel::name).makeEditable()
column("Description", CategoryModel::description).makeEditable()
}
}
right = form {
fieldset {
field("Name") {
textfield(categoryModel.name)
}
}
fieldset {
field("Description") {
textfield(categoryModel.description)
}
}
button("ADD CATEGORY") {
action {
dbController.addCategory(categoryModel.name.value, categoryModel.description.value)
}
}
}
}
}
I apologize for huge amount of code, also in last code snipped i left questions in form of comments where i fail to achive desired results.
I am sure i am not properly binding code, i just dont see why, also i sometimes use one variable to update data, my declared one "categoryModel" and sometimes i use tableview.selecteditem, it just seems hacky and i cant seem to grasp way.
Thank you!
Is there a plugin for the ExtJS Grid that automatically hides "empty" columns?
A column should be deemed "empty" if the value of the mapped field for all Records in the underlying store matches a given "emptiness" criteria (a given value or, better, a function).
Run-time add/remove/update operations on the underlying store should hide/un-hide columns accordingly.
Thanks!
I had to do something similar to this... here is a "Hiding Column Model" that will hide/show columns based on the return value of the "fieldHasData" method... it is probably a close start to what you were asking
Ext.ux.grid.HidingColumnModel = function() {
var Class = Ext.extend(Ext.grid.ColumnModel, {
constructor:function(config) {
Class.superclass.constructor.call(this, config);
},
onGridStoreLoad:function(store, records, options) {
store.fields.each(function(item, index, length) {
var colIndex = this.findColumnIndex(item.name);
if (colIndex >= 0) {
this.setHidden(colIndex, !this.fieldHasData(item.name, records));
}
}, this);
},
fieldHasData:function(field, records) {
var hasData = false;
Ext.each(Ext.pluck(records, "data"), function(item, index, allItems) {
if (item[field]) {
hasData = true;
}
});
return hasData;
}
});
return Class;
}();
And then in your grid... do add the listener on the column model
var columnModel = new Ext.ux.grid.HidingColumnModel(),
store = ... {create your store},
gridPanel = new Ext.grid.GridPanel({
...
store:store,
columnModel:columnModel,
...
});
store.on('load', columnModel.onGridStoreLoad, columnModel);
Since I could not find a similar plugin anywhere, I just implemented it myself :)
The code is on the extjs/sencha forums here:
http://www.sencha.com/forum/showthread.php?140685-Grid-Plugin-dynamically-hiding-columns-matching-quot-emptiness-quot-criteria&p=626670#post626670
I have a datagridcolumn where a labelFunction is defined:
private function myLabelFunction(item:Object, column:DataGridColumn):String
{
var returnVal:String;
var nm:NumericFormatter;
nm.decimalSeparatorTo = ".";
nm.precision = additionalParameter;
returnVal = nmTwoDecimals.format(item[column.dataField]);
if (returnVal == '0.00')
{
returnVal = '';
}
return returnVal;
}
Would it be possible to add an additional parameter so that I could pass the property values for the formatter which I intend to use?
Like for example:
private function myLabelFunction(item:Object, column:DataGridColumn, precisionParam:int):String
{
var returnVal:String;
var nm:NumericFormatter;
nm.decimalSeparatorTo = ".";
nm.precision = precisionParam;
returnVal = nmTwoDecimals.format(item[column.dataField]);
if (returnVal == '0.00')
{
returnVal = '';
}
return returnVal;
}
Thanks.
You would have to extend the DataGridColumn class. After creating your new class simply override the existing itemToLabel function:
public function itemToLabel(data:Object):String
{
if (!data)
return " ";
if (labelFunction != null)
return labelFunction(data, this);
if (owner.labelFunction != null)
return owner.labelFunction(data, this);
if (typeof(data) == "object" || typeof(data) == "xml")
{
try
{
if ( !hasComplexFieldName )
data = data[dataField];
else
data = deriveComplexColumnData( data );
}
catch(e:Error)
{
data = null;
}
}
if (data is String)
return String(data);
try
{
return data.toString();
}
catch(e:Error)
{
}
return " ";
}
The line 'return labelFunction(data, this);' is what calls the labelFunction (will also check the owner datagrid for a labelfunction). 'data' in 'itemToLabel' is your object. You could either include the precision value you want in the object or hard code it in the extended class (or inject, or singleton, class var, whatever you like).
At this point you can go ahead and pass it as a third parameter to your new labelFunction.
In your label function for the datagrid column, you can access the assigned data field by using the dataField property, see the following syntax below:
"supposing your label function is called formatNumbers_LabelFunction"
private function formatNumbers_LabelFunction(item:Object, column:DataGridColumn):String{
//Write any code logic you want to apply on your data field ;)
//In this example, I'm using a number formatter to edit numbers
return myCustomNumberFormatter.format(item[column.dataField]);
}
This way, you can use a generic label function to handle some unified operations on your displayed data
And besides that, you can also access to any data field that is in the data provider by just calling its name like this:
item.YourFieldName
where item is the firs parameter [of type Object] in your label function method
This would work:
<DataGridColumn labelFunction="{function(item:Object, column:DataGridColumn):String { return anotherLabelFunction(item,column,2) }}" />
// Elsewhere ...
function anotherLabelFunction(item:Object,column:DataGridColumn,precision:int):String
{
// Do your business
}
