找不到组件工厂。您是否将其添加到@ NgModule.entryComponents? [英] No component factory found. Did you add it to @NgModule.entryComponents?
问题描述
在将ag-grid与angular4一起使用时,我会遇到以下错误消息。
While using ag-grid with angular4, I'm stuck with below error message.
我正在尝试通过HTTP提取json后显示行数据。 / p>
I'm trying to display row data after fetch json via HTTP.
this.gridOptions.api.setRowData(this.gridOptions.rowData);
但是我的代码是在错误消息下面制作的。
But my code made below error message.
错误错误:没有为RedComponentComponent找到组件工厂。您将
添加到@ NgModule.entryComponents吗?
ERROR Error: No component factory found for RedComponentComponent. Did you add it to @NgModule.entryComponents?
这是我的应用程序模块代码。我已经设置为entryComponents。
This is my app module code. I'd already set to entryComponents.
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AgGridModule} from "ag-grid-angular/main";
import { AppComponent } from './app.component';
import { MyGridApplicationComponent } from './my-grid-application/my-grid-application.component';
import { RedComponentComponent } from './red-component/red-component.component';
@NgModule({
imports: [
BrowserModule,
AgGridModule.withComponents(
[RedComponentComponent]
),
FormsModule,
HttpModule
],
declarations: [
AppComponent,
MyGridApplicationComponent,
RedComponentComponent
],
entryComponents: [
RedComponentComponent
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
我的问题。为什么此代码无法解析此组件。
My Question. Why this code can't resolve this component.
推荐答案
您正在传递 string $ c $从服务器加载数据时,c>到`ComponentFactoryResolver,但它应该是组件类型。
You are passing string
to `ComponentFactoryResolver when loading data from server but it should be component type.
header.json
{
"headerName": "DetailCode",
"field": "detailCode",
"cellRendererFramework": "RedComponentComponent", // string
"width":100
},
要解决它,我会创建条目组件图,例如:
to solve it i would create entry components map like:
entry-components.ts
import { RedComponentComponent } from './red-component/red-component.component';
export const entryComponentsMap = {
'RedComponentComponent': RedComponentComponent
};
然后从json字符串映射加载到组件类
and then map loading from json string to component class
comm-code-grid-option.service.ts
private fetchColumnDefs() {
console.log("fetchColumnDefs()");
this.http.get(this.API_URI + "resident/header.json").subscribe(
r => {
this.gridOptions.columnDefs = r.json();
this.gridOptions.columnDefs.forEach((x: any) => {
if (x.cellRendererFramework) {
x.cellRendererFramework = entryComponentsMap[x.cellRendererFramework];
}
});
