btc-weasy-pdf 0.3

Quick start

1. Add “weasy_pdf” to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = (
       ...
       'weasy_pdf',
   )

2. Help functions: safety_get_attribute(), safety_parse_dict(), format_date() (see utils.py)

3. Create data-object. When using the safety_get_attribute() function do not forget to join the related tables (prefetch_related, select_related):

   class PDFDataObject:
   
       def __init__(self, data_obj: MyModel):
           get = safety_get_attribute
           self.data_obj = data_obj
   
           self.first_name = get(data_obj, 'first_name')
           ...

4. Prepare PDF template. Use built-in template filters: times, parse_dict:

   <!doctype html>
   <html lang="en">
       <head>
           <meta charset="utf-8">
   
           {% load static %}
           {% load weasy_pdf %}
   
           <link rel="stylesheet" href="{% static '/styles/pdf.css' %}">
   
           <title>Title</title>
           <meta name="description" content="Description">
           <meta name="author" content="Author">
   
       </head>
       <body>
           <span>{{ data_object.first_name }}</span>
           ...
       </body>
   </html>
   
   <!-- Filters usage:
   
   {% for i in 8|times %}
       <td colspan="2"></td>
   {% endfor %}
   
   <td colspan="5">{{ data_object|parse_dict:'0__NAME' }}</td>
    -->

5. Prepare view:

   class PDFView(WeasyPDFViewMixin):
   
       template_name = 'pdf.html'
       file_name = 'my_pdf.pdf'
   
       def get_object(self) -> Any:
           passport = get_object_or_404(Passport, pk=self.kwargs.get('pk'))
           return PDFDataObject(passport)
