sql model config(dataset='ds_name') combined with profiles.yml dataset configuration, not right

[wanalytics8]

Hi,

if my profiles.yml has

my_conf:
  target: dev # default target
  outputs:
    dev: #default target name
      dataset: my_ds_name

while my model_1.sql has

{{
    config(
        materialized='view'
 ,dataset='my_ds_name' 

    )
}}

then after I run dbt -s model_1.sql --target dev

the model will be saved to:

project.my_ds_name_my_ds_name.model_1

Is this an intended behaviour?( string concatenation from both places that I specified dataset)?

Or shall I never use config() to specify dataset, if I use --target?

Is this relevant to global macro generate_schema_name()?

Thanks!
