This is the first of a series of blog posts that deals with Plone migrations.
Implementing content-types for Plone site is one part of every typical Plone project. Styling & testing is another one. Both testers and designer need content for testing.
As part of a new project I decided to provide example content for each new content-type. The two core components are the loremipsum module for Python and the lorempixel.com web-service. The Python module can be used to generate single sentences of text or multiple paragraphs of text. The web-service provided random images in arbitrary sizes for you.
Here is a picture of a sample glossary
and one of a simple picture database:
Here is some example code for generating content and random image from using the mentioned services:
def gen_paragraphs(num=3): return u'/'.join([p for p in loremipsum.Generator().generate_paragraphs(num)])
def gen_sentence(): return loremipsum.Generator().generate_sentence()[-1]
def gen_sentences(length=80): return u'/'.join([s for s in loremipsum.Generator().generate_sentences(length)])
def random_image(width, height): url = 'http://lorempixel.com/%d/%d/' % (width, height) return urllib2.urlopen(url).read()
The code for generating a gallery as seen above looks like this:
def installAssets(self, site): service = site.restrictedTraverse('deutschland/de/service') assets = invokeFactory(service, 'Folder', 'Assets') for width,height in ((200,200), (400,400), (600, 400), (800, 600), (800,800), (1024, 768)) imagefolder_id = '%sx%s' % (width, height) images = invokeFactory(assets, 'Folder', imagefolder_id) for i in range(20): img = invokeFactory(images, 'Image') img.setImage(random_image(width, height)) img.reindexObject()
The invokeFactory() method used here is just a tiny wrapper around the standard invokeFactory() method of a folder object that generates a random title and a normalized id for the new content object plus doing some pre-allocation of the description and text field (if available) on the created content-object.
The complete code can be found on the website of my Plone partner Veit Schiele (German only).
