Question

I am using pdftk like this

pdftk template.pdf fill_form /temp/input.fdf output /temp/output.pdf

Now this is working fine

But now i have generated the temporary file instead of /temp/input.fdf with this

myfile = tempfile.NamedTemporaryFile()
myfile.write(fdf)
myfile.seek(0)
myfile.close()

Now i don’t know how can i pass myfile as input to the pdftk

Answer 1

myfile.name will get you the file path.

Note that tempfiles do not exist after close(). From the docs:

 tempfile.TemporaryFile([mode='w+b'[, bufsize=-1[, suffix=''[, 
    prefix='tmp'[, dir=None]]]]])

Return a file-like object that can be used as a temporary storage
area. The file is created using mkstemp(). It will be destroyed as
soon as it is closed (including an implicit close when the object is
garbage collected). Under Unix, the directory entry for the file is
removed immediately after the file is created. Other platforms do not
support this; your code should not rely on a temporary file created
using this function having or not having a visible name in the file
system.
