[Django]-Django ReportLab error – 'str' object has no attribute 'getKeepWithNext'

You are only allowed to add reportlab’s Flowable‘s to the story. If you want to append an image, you have to do it the reportlab way:

change

elements.append('<img src="el45.jpg" height="5">')

to

elements.append(Image('el45.jpg', width=None, height=5))

You have to play with the width and height parameter. Also, you should always multiply the size with the wanted unit, e.g. 5*inch. For further infos, please see chapter 9.3 of the reportlab userguide!
