Assuming that my angular app is provided data shaped as:
[
{
name: 'object1',
type: 'checkbox'
},
{
name: 'object2',
type: 'dropdown',
options: ['opt1-1', 'opt1-2']
},
...
]
The aim is to populate the DOM with these objects. The type of elements I can have (such as checkbox, dropdowns) is predefined. Also, I will need these to interact together as they will be part of an interactive form. How can I store references to these on the ts side.

react-redux-firebase supports replacing ids with the corresponding value in a lookup object – like a join – through a config object called populates (and later using a convenient mapping function inside mapStateToProps).
Unfortunately, the documentation of react-redux-firebase is rather rudimentary in this area (and in others)...
Can someone tell me, whether it's possible to populate a list of ids?
For example:
// from:
{ friends: [1, 27, 42] }
// to:
{ friends: [
{ id: 1, name: 'Charlie' },
{ id: 27, name: 'Parker' },
{ id: 42, name: 'Brown' },
] }
Testing version 3.0.0, it seems that populating a list works exactly the same as replacing a single field. Instead of receiving back an object you will receive an array of replaced objects.
I am trying to display my json from a mvc controller to be displayed on a checkboxed kendo ui treeview. The code on the asp.net mvc view and the json sent to the view are given below
MyDoc.cshtml code
<script>
$("#treeview").kendoTreeView({
checkboxes: {
checkChildren: true,
},
dataSource: {
//type: "odata",
transport: {
read: {
url: '#Url.Content("~/Document/GetMyDocs")',
type: "post",
dataType: "json"
}
},
schema: {
model: {
id: "id", text:"Name",
children: "Files"
}
}
},
dataTextField: [ "Name"],
check: onCheck
});
json object
[{"id":1,"Name":"Checking",
"Files":[{"Filename":"doc10","id":"1afd5a4f-086f-44d2-9287-8098384e379e"},
{"Filename":"doc11","id":"89ea3366-14b8-4e91-8273-6e2a51fbe516"}]},
{"id":2,"Name":"Saving",
"Files":[{"Filename":"doc20","id":"c7a88f5d-067e-4f20-93b6-da6eff69d532"},
{"Filename":"doc21","id":"8a0a62ed-1b4a-4e5e-8d59-d57a975a7ab0"}]}]
When I view the page only the toplevel text, "Checking" and "Saving" shows. The date present under Files comes out as undefined.
Thanks
It looks like that Kendo UI uses the dataTextField: [ "Name"] for both the parent and the child node. Since the json in the child data doesn't have a field name equal to "Name" it came out as undefined. Once I changed the property, "FileName" into "Name", it worked. The Telerik's documentation is as atrocious as other third party controls. All their demos are more geared to show how easy peasy it is to create a sexy looking UI using few hard coded data than showing how to create a real world application!
I am copying html code which has "ul","li" tags, clicking "Source" and pasting it to CKEditor. However, when i go to design, it replaces those tags with "". Is this a bug or did i configure something wrong? Below is the config.js file content.
CKEDITOR.editorConfig = function (config) {
// Define changes to default configuration here.
// For the complete reference:
// http://docs.ckeditor.com/#!/api/CKEDITOR.config
// The toolbar groups arrangement, optimized for two toolbar rows.
config.toolbarGroups = [
{ name: 'clipboard', groups: ['clipboard', 'undo'] },
{ name: 'editing', groups: ['find', 'selection', 'spellchecker'] },
{ name: 'links' },
{ name: 'insert' },
{ name: 'forms' },
{ name: 'tools' },
{ name: 'document', groups: ['mode', 'document', 'doctools'] },
{ name: 'others' },
'/',
{ name: 'basicstyles', groups: ['basicstyles', 'cleanup'] },
{ name: 'paragraph' },
{ name: 'styles' },
{ name: 'colors' },
{ name: 'about' }
];
// Remove some buttons, provided by the standard plugins, which we don't
// need to have in the Standard(s) toolbar.
config.removeButtons = 'Underline,Subscript,Superscript';
config.filebrowserImageBrowseUrl = '/Admin/BrowseImage';
config.filebrowserImageUploadUrl = '/Admin/UploadImage';
I'm assuming that you're using latest CKEditor (4.1) which comes with Advanced Content Filter. It means that lists will be cleared out of your content unless you have either list plugin loaded with all the features (buttons and commands) or explicitly defined config.allowedContent to accept lists.
It also means that if you remove list buttons, editor assumes that you don't want list in your content and they're simply gone. Your config.toolbarGroups has no list entry and this the root of your problem. You can check whether tag is allowed by typing this in your console:
CKEDITOR.instances.yourEditorInstance.filter.check( 'li' );
>> false
When you add something like this to your config, lists will be back in the editor with UI:
{ name: 'paragraph', groups: [ 'list' ] }
If you really want to preserve your toolbar but allow lists, you can specify:
config.extraAllowedContent = 'ul ol li'.
Also read more about allowedContent rules to know more and use things intentionally.
I have a use case where I would like to have jqGrid display some raw JSON for a particular column. I have the following JSON being sent from the server:
{"items":[
{
"code":"ABC123",
"description":"",
"custom_data":{"items":[
{"prop1":"val1","prop2":"val2"},
{"prop1":"val3","prop2":"val4"}
]}
},
{"code":"ABC124","description":"","custom_data":[]},
...,
]}
and a jqGrid configuration like so:
{
url:'/api/somewhere',
datatype: "json",
jsonReader : {
root:"items",
repeatitems: false,
id: "code"
},
colNames:['Code',
'Description',
'Data',],
colModel:[
{
name:'code', index:'code', width:100, hidden:false,
edittype:'text',
editable: true,
editrules:{required:true, edithidden:true},
editoptions: {readonly:false}
},
{
name:'description',
index:'description',
width:250,
editable:true,
edittype:'text',
editrules:{required:true}
},
{
name:'custom_data',
index:'custom_data',
width:100,
hidden:true,
sortable:false,
editable:true,
edittype:'text',
editrules:{required:false, edithidden:true}
},
],
...,
The grid displays OK, but the custom_data column is displayed as [object Object]. What I need is for it to display the raw JSON string I have tried calling JSON.stringify on the custom_data object for each row object using the loadComplete event, but that didn't work. I need to do some data manipulation after the GET anyway, as I want to delete null values from the custom_data object.
My users are comfortable reading and editing raw JSON, so I also need the add/edit form to accept raw JSON which will then get POSTed.
I'm not sure if I'm simply using the wrong event to convert the object back to a string, or if there is something else going on.
What you can do is usage of custom formatter for "custom_data" column
formatter: function (cellValue, options, rawData) {
return cellValue.items ? JSON.stringify(cellValue.items) : "";
}
I changed in the demo hidden property for "custom_data" column to true to see the data
Additionally you can consider to use userdata instead of hidden column to save additional custom data. I recommend you to read the answer additionally which shows not only how to use userdata, but additionally how to show additional data in form subgrid.
I am loading JQGrid from an API, one of the data structures that I have for my grid is a JSON element formatted as such:
{"id":123,"name":"John Doe","username":"john.doe"}
The data is properly displayed in the grid, however if I try to type in the toolbar search, I do not get a match presumably because jqgrid still has the above JSON stored as an object.
A truncated version of my grid is as follows:
$('#test').jqGrid({
...
loadonce: true,
datatype: 'local',
colModel: [
{name:'test', index:'test', label:'Test', formatter:customFormatter}
],
...
});
function customFormatter (cellvalue,options) {
return cellvalue.name;
}
I found this post that seems to address this very matter, however I am struggling to get my head around as to how to use this for a JSON object. Once the grid is loaded, I don't see a reason as to why the local data should be anything other than string (Until the grid is reloaded).
After stumbling upon the JSON dot notation in the docs, and adding it to the index this now works:
colModel: [
{name:'test.name', index:'test.name', label:'Test'}
]
You should choose name property of colModel which corresponds the names of the properties in the JSON input. So it's native to use just
colModel: [
{name: "name", label: "Name"}
{name: "username", label: "User Name"}
]
If you do need to remap some names in the JSON input to another names in the colModel you should use jsonmap property. For example
colModel: [
{name: "test1", label: "Name", jsonmap: "name"}
{name: "test2", label: "User Name", jsonmap: "username"}
]
The usage of index different as name is not possible in case of usage of loadonce: true. It is not recommended to use values of name property which have . or any other meta-character. The restriction exist because the name property will be used to build id property of many elements of the grid.
