Hartl Rails教程第7章错误仍然为黑色的字段

Question

In part 7.3.3 all input fields with class="form_control" nested in divs with class="field_with_errors" should be colored red . But this is what I get.

custom.scss includes:

#error_explanation {
  color: red;
  ul {
    color: red;
    margin: 0 0 30px 0;
  }
}

.field_with_errors {
  @extend .has-error;
  .form-control {
    color: $state-danger-text;
  }
}

As you can see from the screenshot #error_explanation works well, .field_with_errors does not. What could be wrong with it?

html模板的代码中有一个错字，因此将输入字段class: 'form_control'更改为class: 'form-control'解决了该问题
