Я строю динамическую сетку Kendo UI с динамическими столбцами. Не удается отобразить данные в сетке.
Я использую ASP.NET Core webAPI, который возвращает динамические столбцы и их данные.
Я следил за этой статьей .
В моем событии успешного вызова API я выполняю следующую логику:
onSuccess: function (readings) {
console.log(readings);
var myCoulmns = [];
var myFields = {}; // I am not using this
var model = generateModel(readings[0]);
readings.forEach(function (obj) {
for (key in obj) {
console.log(key + ': ' + obj[key]);
if (key === "Id") {
myCoulmns.push({
field: key,
title: key,
width: 240,
hidden: true
});
myFields["Id"] = { type: "number" };
}
else if (key === "RadioChannel") {
myCoulmns.push( {
field: "RadioChannel",
title: "Radio Channel",
width: 240
});
myFields["RadioChannel"]= { type: "string" };
}
else if (key === "Units") {
myCoulmns.push( {
field: "Units",
title: "Units",
width: 150
});
myFields["Units"] = { type: "string" };
} else {
myCoulmns.push( {
field: key,
title: getFormatedDate(key),
width: 200
//format: "{0:n}"
});
myFields[key] = { type: "number" };
}
}
});
$("#monitorReadingGrid").kendoGrid({
dataSource: {
schema: {
model: model
},
data: readings,
pageSize: 20
},
columns: myCoulmns,
height: 550,
scrollable: true,
sortable: false,
filterable: false,
//columMenu:true,
pageable: {
input: true,
numeric: false
}
});
//$("#montior-data").show();
}

var isDateField = [];
function getFormatedDate(key) {
var day = key.substr(0, 2);
var month = key.substr(2, 3);
var year = key.substr(5, 4);
var hour = key.substr(9, 2);
var minute = key.substr(11, 2);
var tt = key.substr(13, 2);
return month + " " + day + ", " + year + " " + hour + ":" + minute + " " + tt;
}
function generateModel(dataItem) {
var model = {};
var fields = {};
for (var property in dataItem) {
if (property.indexOf("Id") !== -1) {
model["id"] = property;
}
var propType = typeof dataItem[property];
if (propType === "number") {
fields[property] = {
type: "number",
validation: {
required: true
}
};
if (model.id === property) {
fields[property].editable = false;
fields[property].validation.required = false;
}
} else if (propType === "boolean") {
fields[property] = {
type: "boolean"
};
} else if (propType === "string") {
var parsedDate = kendo.parseDate(dataItem[property]);
if (parsedDate) {
fields[property] = {
type: "date",
validation: {
required: true
}
};
isDateField[property] = true;
} else {
fields[property] = {
type: "string",
validation: {
required: true
}
};
}
} else {
fields[property] = {
validation: {
required: true
}
};
}
}
model.fields = fields;
return model;
}
Вот данные, которые возвращаются из webAPI:

Если я меняю источник данных (рекомендую схему), я получаю неверную ошибку шаблона, но я не использую никаких шаблонов в сетке.
