ExtJs deleting element from store doesn't work

I'm working with ExtJs 6.2.0 and Java Spring MVC for the REST API.
I'm trying to delete an object from one of my store but I'm having a problem : instead of using my id named idCamp, extjs is using the field named id that contains an extjs generated id (for example: extModel47-1).
I'm working on the delete part but I didn't try to update a camp nor fetch one, but I think the configuration is the same for these three operations that need the id.
Here is my store:
Ext.define('XXXXXX.store.Camps', {
extend: 'Ext.data.Store',
alias: 'store.camps',
model: 'XXXXXX.model.Camp',
fields: [
'idCamp', // More irrelevant fields
],
autoLoad : true,
autoSync: true,
storeId: 'storeCamp',
proxy: {
type: 'rest',
idParam: 'idCamp',
url: // irrelevant,
reader: {
type: 'json',
rootProperty: 'data'
},
writer: {
type: 'json'
}
}
});
Here is my model:
Ext.define('XXXXXX.model.Camp', {
extend: 'Ext.data.Model',
idProperty: 'idCamp',
fields: [
{ name: 'idCamp', type: 'int' },
// More irrelevant fields
]
});
I also tried to put an idProperty inside the writer/reader inside the proxy but it didn't do anything.
Forgive my poor usage of the English language since I'm a French people.

The issue is using a combination of fields/model in your store definition. They are in competition with each other. Remove the fields definition.

Ext JS dynamic store insert Cannot read property 'isModel' of undefined

I dynamically create my store from a model relation and attach this store to a grid.
var map = record.getCommunity().mappings();
map.load({
url: '/myUrl/mappings',
scope: this,
callback: function(records, operation, success) {
map.group('type');
//ExtJS bug https://www.sencha.com/forum/showthread.php?265674
me.getOutgoingGrid().destroy();
childGrid = Ext.create('hds.view.outgoingGrid', {
store: map
});
me.getGridHolder().add(childGrid);
me.getOutgoingGrid().getSelectionModel().select(0, false) ;
}
});
When I want to create a new model instance and insert it into this dynamic store I get the following error:
Cannot read property 'isModel' of undefined
Here is the code that triggers the error:
var newMap = Ext.create('hds.model.MappingModel', {
indetifier : "something",
});
me.getOutgoingGrid().store.insert(0, newMap);
I cannot found the reason of this problem....Any ideas?

It is hard to know what is breaking your code but here are a couple of things:
1 - You need to define the model identifier in the class prototype not in the instance.
2 - You misspelled identifier
So your model should look like:
Ext.define('hds.model.MappingModel', {
identifier : "something",
});
var newMap = new hds.model.MappingModel({
//...your config here
});
The error that you are seeing Cannot read property 'isModel' of undefined is thrown when the store tries to check if model is an instance of Ext.data.Model but the model being passed is undefined.
This can happen for several reasons but usually it's because you are trying to create a model before the prototype has been defined or because there is a typo on your code.
Please, try creating a a fiddle (https://fiddle.sencha.com) reproducing this error or it will be very hard to help you.
Regards,

If there was an fiddle, It would be more helpful. As I understand from your question, you have some data and you can't set the data to store or model correctly. If you had defined your model or store before set to grid, there would not be a problem. I added a fiddle how model proxy works with store and etc. Hope it helps. If the fiddle does not explain your problem, please change the fiddle codes. So, we can understand what your problem exactly. Here is the fiddle: https://fiddle.sencha.com/#fiddle/tvq
Ext.define('model.Users', {
extend: 'Ext.data.Model',
fields: [
{ name: 'Name', type: 'string'},
{ name: 'City', type: 'string'},
{ name: 'Country', type: 'string'},
],
//idProperty: 'Name',
proxy: {
type: 'ajax',
rootProperty: 'records',
rootUrl: 'users', // used when updating proxy url
url: 'users',
reader: {
type: 'json',
rootProperty: 'records'
}
}
}); //model
var modelExt = Ext.create('model.Users', { Name: 'Ernst Handel'});
var storeExt = Ext.create('Ext.data.Store', {
requires: 'model.Users',
model: 'model.Users'
});
modelExt.load({
scope: this,
success: function(record) {
var colObjects = [];
Ext.each(Object.keys(record.data), function(key) {
colObjects.push({
text: key,
dataIndex: key
});
});
storeExt.loadData([record]);
//console.log(record, storeExt);
var grid = Ext.create('Ext.grid.Panel', {
store: storeExt,
columns: colObjects,
renderTo: Ext.getBody()
});
},
failure: function (err) {
}
});

Create model like this and then use.
var newMap = Ext.create('Ext.data.model', {
identifier : "something"
});

Add a new file in Model folder named like MappingModel.js and define model like this.
Ext.define('hds.model.MappingModel', {
extend: 'Ext.data.Model',
fields: [
'something'
]
});
Add this in app.js and then use MappingModel in your dynamic store.

Save nested form data back to server in ExtJS

I have a Model that contains an association to another Model. I am able to display the nested data into a form by using the mapping attribute on the field. Example:
Ext.define('Example.model.Request', {
extend: 'Ext.data.Model',
fields: [
{
name: 'id',
type: Ext.data.Types.NUMBER,
useNull: false
}
{
name: 'plan_surveyor',
mapping: 'plan.surveyor',
type: Ext.data.Types.STRING
}
],
associations: [
{type: 'hasOne', associationKey: 'plan', getterName:'getPlan', model: 'Specs.model.Plan'}
],
proxy: {
type: 'direct',
api: {
read: requestController.load,
update: requestController.update,
},
reader: {
type: 'json',
root: 'records'
},
writer: {
type: 'json',
writeAllFields: true,
nameProperty: 'mapping'
}
}
});
Using this method, I can display the plan.surveyor value in the form by reference plan_surveyor. I call Form.loadRecord(model) to pull the data from the model into the form.
However, now that I'm trying to send the data back to the server, I get the error:
Error performing action. Please report the following: "Unrecognized field "plan.surveyor"
I am attempting to save to the server by first calling Form.updateRecord(model), then model.save(). Is there a way to have the Writer understand that 'plan.surveyor' is not a property name but instead to properly handle nesting?
Am I doing this the right way to start with, or should I just be handling the setting of the form data and loading back into the model in a more manual fashion? It seems that nested data is not all that well supported in general - any recommendations?

Ext.define('Example.model.Request', {
extend: 'Ext.data.Model',
fields: [
{
name: 'id',
type: Ext.data.Types.NUMBER,
useNull: false
}
{
name: 'plan_surveyor',
mapping: 'plan.surveyor',//change to 'plan_surveyor'
type: Ext.data.Types.STRING
}
],
change that show in comment ,because data index is given in above format because ur give ur format thata time that is not dataindex it's a column or extjs preparatory ,so please change that may it's work well
it's not work u will send hole code

Sencha Touch 2 array parsing

I'm new to sencha touch and I'm trying to parse an array of data (this doesn't seem like an uncommon use case but I can't find anything about it online). I followed the sencha ext.data.reader.json doc on nested json, but it doesn't work. Here are my models:
Search Results (to hold multiple search results):
Ext.define('GS.model.SearchResults', {
extend: 'Ext.data.Model',
autoLoad: true,
config: {
fields: [
{name: 'query', type: 'string'},
],
hasMany : {model: 'SearchResult', name: 'results'},
}
});
And search result, to hold an individual search result
Ext.define('GS.model.SearchResult', {
extend: 'Ext.data.Model',
config: {
fields: [
{name: 'id', type: 'int'},
{name: 'name', type: 'string'}
],
belongsTo: 'SearchResults'
}
});
Then in my controller, I have this code:
var store = Ext.create('Ext.data.Store', {
autoLoad: "true",
model: "GS.model.SearchResults",
proxy:
{
type: 'ajax',
url : 'www.someurl.com/?query=somequery',
reader: {
type: 'json'
}
}
});
store.load({
callback: function() {
console.log("Done Loading");
var root = store.first();
console.log("Results for " + root.get('query')); //this prints correctly
console.log(root.results());//THIS IS THE LINE IM INTERESTED IN
console.log(root.raw.results);//this weirdly works
//now I want to print each search results name
root.results().each(function(result) {
console.log("Song: " + result.get('name'));
});
}
});
}
When I log root.results(), I get
Uncaught TypeError: Object [object Object] has no method 'results'
This is exactly how they do it in the docs, so does anyone know why this isnt working???
Edit: Here is the doc I was following

The best way to check your error is to debug in chrome console. After callback you will find your records in root.raw or root.data.
I use to debug in chrome console and write the required code.

After some painful trial and error, I figured it out. In the tutorial, they used unconventional model name, but in my case I needed to use the fully qualified one
So to fix I needed to change
hasMany : {model: 'SearchResult', name: 'results'},
to
hasMany : {model: 'GS.model.SearchResult', name: 'results'},
and same with my deeper model like this:
belongsTo: 'GS.model.SearchResults'
Tough error to catch, but I hope this can help someone else in my position

ExtJS4 Changing data store parameters

If I have a data store on a grid like so:
store = Ext.create('Ext.data.Store', {
fields: [{
name: 'id'
}, {
name: 'filename'
}
// other fields here ...
],
proxy: {
type: 'ajax',
url: 'http://myniftyurl.com/blah',
simpleSortMode: true,
reader: {
type: 'json',
totalProperty: 'total',
root: 'result'
},
extraParams: {
'limit': Ext.get('itemsPerPage').getValue(),
'to': Ext.get('to_date').getValue()
// other params
}
},
model: 'Page',
remoteFilter: true,
remoteSort: true
});
The 'limit' and 'to' value will change based on user input, therein lies the problem. The data store keeps using the original parameters instead of the new inputs. How can I fix this?
Thanks in advance!

I normally load my grids manually by executing the store.load() in the controller.
That way prior to it I can change the store's params like so:
//getForm() retrieves the Ext.basic.Form (from Ext.panel.Form)
var params = this.getForm().getValues();
//Write over
grid.getStore().getProxy().extraParams = params;
//load
grid.getStore().load();
I'm using buffered grids which required a decent amount of rework to get completely working in 4.0.7. But that should work for you.
Another options is to use a beforeload listener but I'm not sure if changing the extraParams by then will do anything. You may be able to modified the Ext.data.Operation object that gets passed to the event handler?
Let me know how that works out for you.
Good luck!
