# Tuesday, February 7, 2017¶

There was one place where I forgot to change “initdb_demo” to “prep”: the initdb_tmp scripts.

I checked in my yesterday’s work for #1466 and then continued working on that ticket. My manual German to-do list is done, but there are some evident fine-tuning.

For example the calendar panel didn’t work out of the box. Users must edit calendar subscriptions in order to use it. So I had to adapt the detail layout for users.User.

The MyEvents table needed revision. At least the first cell should open the detail window on that event when clicked. I changed the __str__() method of lino_xl.lib.cal.models.Event. And MyEvents now uses overview instead of html_text.

I also noted that the detail layout for system.SiteConfig needs to be done. I optimized Lino here by adding the custom_layouts_module attribute for doing such layout customizations. A custom layouts module is useful when you want to modify a layout in a plugin which you don’t want to override otherwise. For example, many applications want to define their own detail_layout for SiteConfig, and they don’t customize anything else in that plugin. In this case it feels like overhead to create a subplugin of lino.modlib.system.

The first applications which use this new feature are lino_avanti.lib.avanti.layouts lino_voga.lib.voga.layouts.

Hangout with Tonis. Tonis observed that in Lino Così there is no sales price in the detail of a product. We fixed that together (Tonis watching me), using the new feature. That, we now have a module lino_cosi.lib.cosi.layouts which adds the sales price to the prodct detail window.

Tonis said that it is a quite hackerish way of doing things, and that in Odoo you simply modify some xml file when you want to change a layout. It is an understandable reaction. But this is one of the important design choices I made for Lino: the UI layouts are done using Python, and not in XML or some other additional format.

About 10 minutes later he understood why Lino does it this way, and that thinking in Python is actually cool, and maybe even better. At least if you are a developer and want to reuse your work.
