我是新来的有角度的人，正在做一个表格。我将一个字段设置为带有值的只读字段，但是在发布表单时，我希望该只读值也提交到数据库中。 我正在使用Cloud Firestore作为数据库。因此，我将为您提供帮助。
我做了一些修改，但对我没有用，所以我现在需要做些什么。
这里，我的表格是
<form (ngSubmit)="addWorkshop()" #workshopForm="ngForm" role="form" class="padding-left">
<label>
<h3>Add Workshop</h3>
</label>
<div class="form-group row">
<div class="col-lg-8 col-md-6 col-sm-12">
<label>Commercial Name</label>
<input type="name" class="form-control" id="cname" name="commercialName"
#commercialName="ngModel" [(ngModel)]="model.commercialName" required>
</div>
</div>
<div class="form-group row">
<div class="col-lg-8">
<label for="address">Address</label>
<input type="text" class="form-control" id="address" name="address" #address="ngModel" [(ngModel)]="model.address"
required>

<div class="form-group row">

</div>
</div>
<button type="submit" class="btn btn-default button-color pull-right">Add Workshop</button>
</form>
我添加的功能是：
add(model) {
debugger
let data =
{
ZoneIds:model.ZoneIds,
address: model.address,
commercialName: model.commercialName,
telephone1: model.telephone1,
telephone2: model.telephone2,
tradeLicense: model.tradeLicense,
//workshopID: model.workshopID,
}
// for(var i=0; i< model.ZoneIds.length; i++)
// {
// data.ZoneIds.push(model.ZoneIds[i]);
// }
return new Promise((resolve, reject) => {
resolve(
this.workshopsCollection.add(data).then(x=>{
debugger
let res = x;
})
);
});
}
