Showing page count with ReportLab

Question

Hi everyone!
I'm trying to add a simple "page x of y" to a report made with ReportLab.. I found this old post about it, but maybe six years later something more straightforward has emerged? ^^;
I found this recipe too, but when I use it, the resulting PDF is missing the images..

Answer 1

Just digging up some code for you, we use this:

SimpleDocTemplate(...).build(self.story,
                             onFirstPage=self._on_page,
                             onLaterPages=self._on_page)

Now self._on_page is a method that gets called for each page like:

def _on_page(self, canvas, doc):
    # ... do any additional page formatting here for each page
    print doc.page

Answer 2

I was able to implement the NumberedCanvas approach from ActiveState. It was very easy to do and did not change much of my existing code. All I had to do was add that NumberedCanvas class and add the canvasmaker attribute when building my doc. I also changed the measurements of where the "x of y" was displayed:

self.doc.build(pdf)

became

self.doc.build(pdf, canvasmaker=NumberedCanvas)

doc is a BaseDocTemplate and pdf is my list of flowable elements.
