In this part you will:
- Register a view
- Create and use a template for the view
Topics covered:
- zcml
Una simple vista browser¶
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 another view similar to the demoview already there:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | <configure
xmlns="http://namespaces.zope.org/zope"
xmlns:browser="http://namespaces.zope.org/browser"
xmlns:plone="http://namespaces.plone.org/plone"
i18n_domain="ploneconf.site">
<!-- Set overrides folder for Just-a-Bunch-Of-Templates product -->
<include package="z3c.jbot" file="meta.zcml" />
<browser:jbot
directory="overrides"
layer="ploneconf.site.interfaces.IPloneconfSiteLayer"
/>
<!-- Publish static files -->
<browser:resourceDirectory
name="ploneconf.site"
directory="static"
/>
<browser:page
name="demoview"
for="*"
class=".views.DemoView"
template="templates/demoview.pt"
layer="ploneconf.site.interfaces.IPloneconfSiteLayer"
permission="zope2.View"
/>
<browser:page
name="training"
for="*"
template="templates/training.pt"
permission="zope2.View"
/>
</configure>
|
Add a file browser/templates/training.pt
<h1>Hello World</h1>
- Restart Plone and open http://localhost:8080/Plone/@@training.
- You should now see “Hello World”.
We now have everything in place to learn about page templates.
Nota
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...
