import { Button, Modal, Form, Input, Radio } from 'antd';

interface Values {
  title: string;
  description: string;
  modifier: string;
}

interface CollectionCreateFormProps {
  visible: boolean;
  onCreate: (values: Values) => void;
  onCancel: () => void;
}

const CollectionCreateForm: React.FC<CollectionCreateFormProps> = ({
  visible,
  onCreate,
  onCancel,
}) => {
  const [form] = Form.useForm();
  return (
    <Modal
      visible={visible}
      title="Create a new collection"
      okText="Create"
      cancelText="Cancel"
      onCancel={onCancel}
      onOk={() => {
        form
          .validateFields()
          .then(values => {
            form.resetFields();
            onCreate(values);
          })
          .catch(info => {
            console.log('Validate Failed:', info);
          });
      }}
    >
      <Form
        form={form}
        layout="vertical"
        name="form_in_modal"
        initialValues={{ modifier: 'public' }}
      >
        <Form.Item
          name="title"
          label="Title"
          rules={[{ required: true, message: 'Please input the title of collection!' }]}
        >
          <Input />
        </Form.Item>
        <Form.Item name="description" label="Description">
          <Input type="textarea" />
        </Form.Item>
        <Form.Item name="modifier" className="collection-create-form_last-form-item">
          <Radio.Group>
            <Radio value="public">Public</Radio>
            <Radio value="private">Private</Radio>
          </Radio.Group>
        </Form.Item>
      </Form>
    </Modal>
  );
};

const CollectionsPage = () => {
  const [visible, setVisible] = useState(false);

  const onCreate = values => {
    console.log('Received values of form: ', values);
    setVisible(false);
  };

  return (
    <div>
      <Button
        type="primary"
        onClick={() => {
          setVisible(true);
        }}
      >
        New Collection
      </Button>
      <CollectionCreateForm
        visible={visible}
        onCreate={onCreate}
        onCancel={() => {
          setVisible(false);
        }}
      />
    </div>
  );
};

ReactDOM.render(<CollectionsPage />, mountNode);
