Online registration for Lino Shop¶

This week-end I worked, partly with Sharif, on #4143 (Review handling of the User.partner field), which was triggered by #4121, which we need for Lino Shop. But it is about online registration, a general feature on which we had previously done some work, which went to sleep with the Lino Care project. Now is the moment to wake it up. I also did #2049 (Users don’t need to be partners in Noi) because it is part of the problem. I am now sure that we want to get rid of lino_xl.lib.online.users.

I moved some functionality from lino_xl.lib.online.users to lino.modlib.users:

New plugin option use_verify and User.verify action.
The submit_insert action now always does a nice warning when a username is already taken.
The User.send_welcome_email action is no longer a window action. We don’t want any question about recipient or subject of the mail.

When the User.partner field is empty, and all three fields first_name, last_name and email are non-empty, (and if the user is verified on a site with use_verify set to True), then Lino now automatically creates a contacts.Person based on this data. This automatism does not apply to SiteAdmin users who can edit the partner field manually.

As a side effect I had to review lino_noi.lib.users.UserDetail.

One advantage of not using lino_xl.lib.online.users any more: In Lino Shop we can have a same person with two user accounts: one as a lino_shop.lib.shop.UserTypes.customer and one as a lino_shop.lib.shop.UserTypes.vendor.

These changes caused (trivial) failures in quite some doctest suites because we have now one more view (about.DateFormats), one window action less and one more field in User.

Data migration will be funny: In noi we no longer use online.users: User is no longer a subclass of Person. Might require some magic when migrating production data.

New user role `LedgerPartner`¶

In lino_xl.lib.ledger I added a new role LedgerPartner, and lino_shop.lib.shop.UserTypes.customer and lino_shop.lib.shop.UserTypes.vendor already inherit from it. Next step is to add table views like MyInvoices and MyPayments

Configuring how to represent dates¶

I added a new field User.date_format. It is there for all applications. It is not yet being used, but lino_react is ready to implement it. And lino.modlib.extjs might follow one day.

The Hydra effect¶

Note: The Hydra effect is when you have the impression of not advancing. You cut down one head of the monster and it grows seven new ones. But Lino is like a Hydra, except that it gets more beautiful (not more dangerous) each time you fix a bug. Working on a beast like Lino makes sense only because it is free software.

The documentation framework, even taken on its own, is a full-featured Hydra. But is getting better with each iteration. Now we have a page about it: lino.doctrees.

Some bug in the React text editor¶

I created a comment and then pasted some text into it. This caused my browser page to lock up. Firefox asked me “This page is slowing down your browser. Do you want to stop it?” After stopping it, I had the following messages in the JS console:

Uncaught Error: An error was thrown inside one of your components, but React doesn't know what it was. This is likely due to browser flakiness. React does its best to preserve the "Pause on exceptions" behavior of the DevTools, which requires some DEV-mode only tricks. It's possible that these don't work in your browser. Try triggering the error in production mode, or switching to a modern browser. If you suspect that this is actually an issue with React, please file an issue.

But I was not yet able to systematically reproduce this problem.

Testing online registration ¶

For testing online registration feature, we now have a new function lino.core.auth.utils.activate_social_auth_testing(). These “public secrets” are used for testing social authentication on a localhost. Until now they were available only in noi1e (and noi1r which imports the settings from noi1e). But now they are used also for lino_shop.projects.shop1

I started to write some content for Lino Shop User’s Guide.

Database migration on Jane¶

Today I did two releases to Jane. The first went very smoothly, despite my expectations. I commented:

Wow, despite the fact that I wrote it myself, Lino will always surprise me. It did the data migration without any need to manually change anything in the restore.py file. I am surprised.

And this was only the first surprise. It got even more surprising. I then noticed that the lino.mixins.polymorphic.Polymorphic.mti_navigator field was still there on the Person detail. Explanation: for some reason my inv sdist release in Lino Noi hadn’t worked. PyPI still returned the old version of noi. And only for noi, not for lino, xl and react.

It is interesting to see that the old noi version had been working well together with the new lino and xl.

After releasing noi to pypi for good and running the pull.sh script again, my restore.py finally gave the expected problem:

django.core.exceptions.ValidationError: ['A Person cannot be parent for a User']

My first guess is to simply not create any Partner row for the existing users. Because this probably reflects

    kw = dict()
