The so-called "master" web views, each of which +basically corresponds to a particular table in the DB, are (almost?) entirely +optional. For instance if your organization needs to track customers but not +products, within your Poser app, then you might go so far as to "remove" the +product views from your app. + +If you do this, then e.g. navigating to http://localhost:9080/products/ (or +whatever your URL is) would result in a 404 not found error regardless of user +permissions, i.e. even if you "become root". However by default (using code +generated via scaffold) the product views *are* enabled, so this URL *would* +work. + +Whether or not a given view(s) is "defined" will depend on whether or not the +module containing this view(s) has been "included" by the Pyramid (web app) +Configurator object. In other words we're leveraging this "include" concept +from `Pyramid`_ in order to control which views are brought into the running +app. + +.. _Pyramid: https://trypyramid.com/ + +In practice what that means is usually just that you must curate the list of +views which are included, within your own project. This config thing works +recursively, but we try to keep the primary list within a conventional place. +In our (tutorial's) case this file is at +``~/src/rattail-tutorial/rattail_tutorial/web/views/__init__.py`` and by +default (freshly generated via scaffold) it looks something like this:: + + def includeme(config): + + # core views + config.include('rattail_tutorial.web.views.common') + config.include('tailbone.views.auth') + config.include('tailbone.views.tables') + config.include('tailbone.views.upgrades') + config.include('tailbone.views.progress') + + # main table views + config.include('tailbone.views.brands') + config.include('tailbone.views.customers') + config.include('tailbone.views.customergroups') + config.include('tailbone.views.datasync') + config.include('tailbone.views.departments') + config.include('tailbone.views.email') + config.include('tailbone.views.employees') + config.include('tailbone.views.messages') + config.include('tailbone.views.people') + config.include('tailbone.views.products') + config.include('tailbone.views.reportcodes') + config.include('tailbone.views.roles') + config.include('tailbone.views.settings') + config.include('tailbone.views.shifts') + config.include('tailbone.views.stores') + config.include('tailbone.views.subdepartments') + config.include('tailbone.views.users') + config.include('tailbone.views.vendors') + + # batch views + config.include('tailbone.views.handheld') + config.include('tailbone.views.inventory') + +In our case the only thing we'll remove for now is the "shifts" entry, i.e. we +wish to remove the line that says:: + + config.include('tailbone.views.shifts') + +That's because these views have to do with staff scheduling and time clock +stuff, which (at least for now) we won't concern ourselves with. + +Note that the underlying *tables* which might contain such data, are left in +place within our database. We're just declaring that we do not need our web +app to support master views for interacting with those tables. diff --git a/docs/customize/index.rst b/docs/customize/index.rst new file mode 100644 index 0000000..8986d22 --- /dev/null +++ b/docs/customize/index.rst @@ -0,0 +1,22 @@ + +Customizing the App! +==================== + +Now that you've made it through the "setup" gauntlet, it's finally time for +some fun stuff. + +As we're building this tutorial, at this point our project is *basically* the +same as any other "Poser" project, as generated via scaffold.
