Wrong Indentation for the Layout/MultilineMethodCallIndentation cop

[ydakuka]

Actual behavior

def parse_user_params
  params[:user] =
    params[:user]&.permit(*policy(User).permitted_attributes).to_h
    .merge(
      params[:user_form]
      &.permit(*policy(UserForm).permitted_attributes)
      .to_h,
    )
end

I run the command rubocop -A and I get:

def parse_user_params
  params[:user] =
    params[:user]&.permit(*policy(User).permitted_attributes).to_h
                 .merge(
                   params[:user_form]
                   &.permit(*policy(UserForm).permitted_attributes)
                   .to_h,
                 )
end

Expected behavior

def parse_user_params
  params[:user] =
    params[:user]
    &.permit(*policy(User).permitted_attributes)
    .to_h
    .merge(
      params[:user_form]
      &.permit(*policy(UserForm).permitted_attributes)
      .to_h,
    )
end

or

def parse_user_params
  params[:user] =
    params[:user]&.permit(*policy(User).permitted_attributes)
                 .to_h
                 .merge(
                   params[:user_form]
                   &.permit(*policy(UserForm).permitted_attributes)
                   .to_h,
                 )
end

RuboCop version

ydakuka@yauhenid:~/Work/project$ bin/rails_docker rubocop -V

And the second case:

I have the following code:

def parse_user_params
  params[:user] =
    params[:user]&.permit(*policy(User).permitted_attributes)&.to_h
    &.merge(
      params[:user_form]
      &.permit(*policy(UserForm).permitted_attributes)
      .to_h,
    )
end

I run rubocop -A and get:

def parse_user_params
  params[:user] =
    params[:user]&.permit(*policy(User).permitted_attributes)&.to_h
                 &.merge(
                   params[:user_form]
    &.permit(*policy(UserForm).permitted_attributes)
    .to_h,
                 )
end

Layout/MultilineMethodCallIndentation is for organizing the indentation of multiline method calls that are already broken into multiple lines, not for introducing new line breaks in method chains.
