I'am trying to execute the Association example present in Data binding of Kitchensink example
(http://dev.sencha.com/ext/5.0.1/examples/kitchensink/#binding-associations) in Extjs5. It works fine for me (In my app am using the Json file for my Data part).
Now am trying to move the Customer and Order model to app/model/test/Customer.js and app/model/test/Order.js and modified my dependenciew accordingly.
My Customer Grid is loading fine for me, but on clicking of record Order gris not getting loaded into memeory.
Here am pasting my Sample code for Orders.js file for refrence
Ext.define('myApp.model.test.Order', {
extend: 'myApp.model.Base',
fields: [
{ name: 'date', type: 'date', dateFormat: 'Y-m-d' },
'shipped',
{
name: 'customer',
reference: {
parent: 'test.Customer'
}
}
]
});
In the above file i tried with name: 'customerId' as well but no result :(
Did any body got the same problem? Any help on this is highly appreciated.
Thanks in Advance
Make sure you use a requires config somewhere to be absolutely sure your model classes are all loading. Also check the docs for the reference config:
http://ext5-docs.site/#!/api/Ext.data.field.Field-cfg-reference
Looks like you might want to just try:
{ name: 'customerId', reference: 'myApp.model.test.Customer' }

I want to show dynamic drop down options for each row of ag-grid.
Suppose for each row, department might be different and based on that I plan to filter list of subjects (available option for users to select in dropdown)
Here is my code:
this.gridOptions.columnDefs = {
headerName: 'Department',
field: 'financingCurrency',
editable: false,
suppressSorting: false,
cellClass: 'grid-align'
},
{
headerName: 'Subject',
field: 'subject',
editable: true,
cellEditor: 'select',
filter: 'text',
cellEditorParams: {
values: this.subjects;
},
suppressSorting: false,
cellClass: 'grid-align'
}
}
I am using free version of ag-grid with Angular 2.
Does someone have any idea about it?
If I understand correctly, you want to be able to have different values in the cellEditor based on which department is selected. If that is correct, then you will likely need to do something more complicated dealing with cellEditors. Here is a plnkr that I made that checks if the name starts with a J, if so then it allows a third option.
Please refer to the plnkr for full example, as well as the docs to make sure that you get everything imported/exported in the right places. Here is what is the key importance for you beyond what is on the docs:
agInit(params: any): void {
if (params.node.data.financingCurrency == 'Your Super Department') {
subjects = [...super options...]
} else {
subjects = [...different options...]
}
}
agInit gets called any time editing is started. params has a complicated object, (I suggest console.log()ing it just to see everything that is available to you) but basically the node is referring to the row that the cell is on, and the data is the data for that row, and judging by your colDefs you can get the value of the Department from financingCurrency.
try something similar :
{
headerName: ' MEDICINE NAME ',
field: 'medicine',
cellEditor: 'autoComplete',
cellEditorParams:params => {
return {
'propertyRendered' : 'name',
'rowData': this.medicineList,
'columnDefs' : [{headerName: 'Medicine', field:'name'}]
}
}
},
I want to the delete a few rows in MySQL table using loopabck. But I don't want to use the id to delete the record. I'm trying it in Angular SDK. My code is:
ModelName.destroyById({ fieldName : myValue })
.$promise
.then(function() {
});
I'd be very thankful for ideas.
Seems like you need to use the destroyAll method, which does what you want, but you need to set up remoting for it first, since it's disabled by default:
ModelName.remoteMethod('destroyAll', {
isStatic: true,
description: 'Delete all matching records',
accessType: 'WRITE',
accepts: {arg: 'where', type: 'object', description: 'filter.where object'},
http: {verb: 'del', path: '/'}
});
Then after that you regenerate your Angular client and you can use it like this in the client side:
ModelName.destroyAll({ filter: { fieldName : myValue }}).$promise.then(...)
Note that using destroyAll is risky as if you have any mistakes in your code you will end up losing data. Enabling it to client side might be security concern.
Another way to do this is to write your own remote method which uses destroyAll in turn with proper validation of the inputs.
In order to change the decimal field I have in my table, I need to know how to have a DB migration code to have this change.
Currently the field is represents as (19,2) and need to changed to (19,3) with 3 floating digits after the point.
My database is MySql.
Thanks!
In documentation of LIQUIBASE, have a attr called modifyDataType.
Try this:
databaseChangeLog {
changeSet(author: 'author', id: '1234') {
modifyDataType(columnName: 'column', newDataType: 'DECIMAL(19,3)')
}
}
I think this works fine.
Solved by using: addNotNullConstraint -
changeSet(author: 'roeyg (generated)', id: '1409232538826-2') {
addNotNullConstraint(columnDataType: 'DECIMAL(19,3)', columnName: 'value', tableName: 'period_value')
}
new to ember js, and working on an app using ember-data. If I test with same data using FixtureAdapter, everything populates in the html template ok. When I switch to RESTAdapter, the data looks like it's coming back ok, but the models are not being populated in the template? Any ideas? Here's the code:
App.Store = DS.Store.extend({
revision:12,
//adapter: 'DS.FixtureAdapter'
adapter: DS.RESTAdapter.extend({
url:'http://bbx-dev.footballamerica.com/builderapirequest/bat'
})
});
App.Brand = DS.Model.extend({
name: DS.attr('string'),
numStyles: DS.attr('string'),
vendorId: DS.attr('string')
});
App.BrandsRoute = Ember.Route.extend({
setupController:function(controller){
},
model:function(){
return App.Brand.find();
}
});
And here is the data coming back, but not being inserted into the template!
returnValue: [{numStyles:1, name:Easton, vendorId:6043}, {numStyles:1, name:Louisville Slugger, vendorId:6075},…]
0: {numStyles:1, name:Easton, vendorId:6043}
1: {numStyles:1, name:Louisville Slugger, vendorId:6075}
2: {numStyles:1, name:Rawlings, vendorId:6109}
3: {numStyles:7, name:BWP Bats , vendorId:6496}
4: {numStyles:1, name:DeMarini, vendorId:W002}
status: "ok"
And here is the template:
{{#each brand in model.returnValue }}
<div class="brand-node"{{action select brand}}>
<h2>{{brand.name}}</h2>
<p>{{brand.numStyles}} Styles</p>
</div>
{{/each}}
Any help would be greatly appreciated! I'm not getting any errors, and the data seems to be coming back ok, just not getting into the template. Not sure if the returned dataset needs "id" param?
I am also using the Store congfig to alter the find() from plural to singular:
DS.RESTAdapter.configure("plurals", {
brand: "brand"
});
The way the API was written, its expecting "brand" and not "brands"... maybe its something to do with this??
Thanks in advance.
You have stated:
Not sure if the returned dataset needs "id" param?
Yes you are guessing right, you data coming back from the backend need's an id field set. And if the id field name is different then id you should also define this in ember like so:
App.Store = DS.Store.extend({
revision:12,
//adapter: 'DS.FixtureAdapter'
adapter: DS.RESTAdapter.extend({
url:'http://bbx-dev.footballamerica.com/builderapirequest/bat'
}),
serializer: DS.RESTSerializer.extend({
primaryKey: function (type) {
return '_my_super_custom_ID'; // Only needed if your id field name is different than 'id'
}
})
});
I suppose your Fixtures have an id defined thus it works, right?
Note: you don't need to define the id field at all explicitly, ember add's automatically the id field to a model, so your model is correct.
Here a website that is still a WIP but can be good reference for this conventions
and as stated there:
The document MUST contain an id key.
And this is how your JSON should look like for a collection of records:
{
"brands": [{
"id": "1",
"numStyles": "1",
"name": "Easton",
"vendorId" :"6043"
}, {
"id": "2",
"numStyles": "4",
"name": "Siemens",
"vendorId": "6123"
}/** and so on**/]
}
Note: as you have shown you JSON root is called returnValue this should be called brand or brands if you are not adapting the plurals. See here for reference for the JSON root I'm talking about.
Hope it helps
Alright so I have a project in NodeJS where I'm utilizing Sequelize for a MySQL ORM. The thing works fantastically however I'm trying to figure out if there is a way to specify what fields are being returned on a query basis or if there's even a way just to do a .query() somewhere.
For example in our user database there can be ridiculous amounts of records and columns. In this case I need to return three columns only so it would be faster to get just those columns. However, Sequelize just queries the table for everything "*" to fulfill the full object model as much as possible. This is the functionality I'd like to bypass in this particular area of the application.
You have to specify the attributes as a property in the object that you pass to findAll():
Project.findAll({attributes: ['name', 'age']}).on('success', function (projects) {
console.log(projects);
});
How I found this:
The query is first called here: https://github.com/sdepold/sequelize/blob/master/lib/model-definition.js#L131
Then gets constructed here: https://github.com/sdepold/sequelize/blob/master/lib/connectors/mysql/query-generator.js#L56-59
Try this in new version
template.findAll({
where: {
user_id: req.params.user_id
},
attributes: ['id', 'template_name'],
}).then(function (list) {
res.status(200).json(list);
})
Use the arrays in the attribute key. You can do nested arrays for aliases.
Project.findAll({
attributes: ['id', ['name', 'project_name']],
where: {id: req.params.id}
})
.then(function(projects) {
res.json(projects);
})
Will yield:
SELECT id, name AS project_name FROM projects WHERE id = ...;
All Answers are correct but we can also use include and exclude as well
Model.findAll({
attributes: { include: ['id'] }
});
Model.findAll({
attributes: { exclude: ['createdAt'] }
});
