Q&A
1. First, a detailed control is provided, just for the convenience of selection and display?
——The detail control is also a control, and the control is a tool for the user to input data or display and translate the data in a different way. So it can be said for selection and display.
2. Is there a detailed form field in the basic view just for display?
——Because the custom control also has display fields and form fields, the custom control is for display (translation) on the display page (view), and it has both display and input functions in the form page (processing).
3. The detailed display field is equipped in the basic view, is it also for display?
--Yes
4. The data processor in the basic view is equipped with post-processing, so that the detailed table is actually written. Only here is the detailed table written?
——Currently, our configuration method is to actually write the list in the post-processor of the base view. However, in theory, processors in other places, such as the processor when the control is saved, the view front, and the node processor, can be used as long as they can write data to other tables, but it is reasonable or unreasonable.
