尝试制作从“任务”到“联系”再到“帐户”的向上查询，并遇到麻烦。
public class Editactivity extends AppCompatActivity {
Button submitBtn;
EditText et;
EditText ea;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_edit);
submitBtn = findViewById(R.id.submitBtn);
et = findViewById(R.id.editTitle);
ea = findViewById(R.id.editArtist);
submitBtn.setonClickListener(new View.OnClickListener() {
@Override
public void onClick(View view)
{
// I do not kNow how to pass the values in the constructor
Song newSong = new Song();
Intent intent = new Intent(Editactivity.this,FavoriteActivity.class);
newSong.setArtist(ea.getText().toString());
newSong.setTitle(et.getText().toString());
startActivity(intent);
finish();
}
});
}
}
效果不错，但

Initializing terraform configuration...
Warning: Value for undeclared variable
The root module does not declare a variable named "tag_user_name" but a value
was found in file "/terraform/terraform.tfvars". To use this value,add a
"variable" block to the configuration.
Using a variables file to set an undeclared variable is deprecated and will
become an error in a future release. If you wish to provide certain "global"
settings to all configurations in your organization,use TF_VAR_...
environment variables to set these instead.
Error: No value for required variable

The root module input variable "aws_access_key_id" is not set,and has no
default value. Use a -var or -var-file command line argument to provide a
value for this variable.
Error: No value for required variable

不喜欢Last_Contact_Made__c，它是Contact上的一个字段。为什么会这样？要使其正常工作，我必须更改什么？
TIA，

解决方法
您基本上遇到polymorphic field的问题。
SOQL应该是这样的：
SELECT
Id,Email_Direction__c,Who.Id,Owner.UserRoleId,TYPEOF Who
WHEN Account THEN
Last_Contact_Made__c
FROM
Task
WHERE
Who.Type = 'Contact'
