Edit in angular 4

问题

I am working on Angular 4 project. Here I want to update the form data using firebase key

I have pass the data through component.ts as follow

    this.service.editEnquiry(this.data);

I called editEnquiry() of service. the editEnquiry() is given as follows

editEnquiry(data)
{

    console.log(data);
    console.log(data.key);    
     this.af.list(`/enquirydata/`+key).update(data);
}

I am getting the data in editEnquiry() but its not updating the record in firebase. Its giving me error like this

Supplied parameters do not match any signature of call target.

any help?

回答1:

If you updating the data then you need to use -

AngularFireDatabase.object

please try below solution hope it helps -

editEnquiry(data)
{

    console.log(data);
    console.log(data.key);    
    this.af.object(`/enquirydata/`+key).update(data);
}

we have to pass the key and the edited data and the edited function should be like this

 editEnquiry(key,value)
{

    console.log(key);
    console.log(value);
this.af.object(`/enquirydata/`+ key).update(value);
}

It worked for me
