14. Views I

A simple browser view

Before writing the talk view itself we step back and talk a little about views and templates.

A view in Plone is usually a BrowserView. It can hold a lot of cool python code but we will first focus on the template.

Edit the file browser/configure.zcml and register a new view called training:

  <include package="z3c.jbot" file="meta.zcml" />
  <browser:jbot
    directory="overrides"
    layer="ploneconf.site.interfaces.IPloneconfSiteLayer"

  <!-- Publish static files -->
  <browser:resourceDirectory

    />

  <browser:page
    name="training"
    for="*"
    template="templates/training.pt"
    permission="zope2.View"
    />

</configure>

Add a file browser/templates/training.pt

<h1>Hello World</h1>

We now have everything in place to learn about page templates.

Note

The view training has no python class registered for it but only a template. It acts as if it had an empty python class inheriting from Products.Five.browser.BrowserView but the way that happens is actually quite a bit of magic...
