Migration in D8 is bloody suffering. IT SHOULD NOT BE THIS HARD!
Migrations in D8 follow a 3 step process. Gather the data, massage the data, then save the data into a destination.
Here’s a super simple source excerpt:
Drupal默认是没有时间段duration的概念的，但是可以通过给event添加field字段start-time,end-time曲线救国来实现
进度太滑水今天被boss批评了（望天
本来以为很好实现的功能结果到处找不到哪里可以加连接，简单搜索一下这个功能竟然还有要用插件，试了两个插件以后最后还是找到免插件的解决方案（其实也是写不来token）。
原文：
BY jeni_dc commented 5 years ago I'd just create a view to display that image on my node type. Add another field to store the link in your node, then create a view with two fields, your link and your image. Arrange the fields in your view so the link is first, then the image. Exclude the link field from display. When setting up your image field in the view you'll need to rewrite the results. Select "output this field as a link", and in the link path enter the token for your link field, that will be in the replacement patterns below. Then to make sure your view is only showing the image and link associated with the particular node you are viewing, you'll need to add a contextual filter. Just add a filter for "Content: Nid" and select "Hide view" for when the filter is not available. Then in your panel for your node display, remove the field that was displaying your image and add the view in it's place.

下面习惯性的先看目录结构：
