django pisa - pagenumber just for two or more pages - show pagenumber of total pages

Question

Is there a posibility to show the pagenumber with django pisa just for two or more pages? The template for showing up pagenumber looks like this:

<div id="footerContent">
   <p>Page <pdf:pagenumber></p>
</div>

I think it's necessary to get the number of pages, before they are processed by pisa. Any option to use an if/else statement like this pseudo:

if pages > 1:
 ...
else:
 ...

If you want to display e.g. Page 1/5 (page one of five) it's also necessary to get the count of pages ?! No solution in pisa for that?

Answer 1

This is not possible in the current version of python-pisa. There is however some patches for it. If you use the version of pisa or xhtml2pdf from this github you will be able to get total number of pages.

My template footer looks like this:

<div id="footerContent">
  "Page: <pdf:pagenumber> / <pdf:pagecount>
</div>

Answer 2

I had problem with adding a counter that would tell me what page number i was looking at out of the total amount of pages in the document. It got it to work when i switch the pisa import from:

import ho.pisa as pisa

to

import xhtml2pdf.pisa as pisa 

Install xhtml2pdf with pip

pip install xhtml2pdf

This is what my footer looks like now

<div id="footerContent">
    {%block page_foot%}
        Page <pdf:pagenumber> / <pdf:pagecount>
    {%endblock%}
</div>

Answer 3

I think you can do it without using https://github.com/chrisglass/xhtml2pdf. What i did is, i use page break as below:

<h1 style="display:none">PAGECOUNT</h1>

and CSS for h1 is

h1 {
    page-break-before:always;
}

Now, you can get page count using

<your-html-string>.count('PAGECOUNT') + 1
