generating pdf report with django-easy-pdf

[sum abiut]

Hi,

I am trying to generate pdf reports using django-easy-pdf but some how i am not geting the data. 

here is what i get. i only get the header but not the data.  i think i am missing something from class viewpdfreport that i can't seem to figure it ou

Here is my view.py:

from django.shortcuts import render
from django.shortcuts import render_to_response
from django.conf import settings
from django.views.generic import TemplateView
from eLeave.views import govoffice

from eLeave.models import newleave


from easy_pdf.views import PDFTemplateView

class viewpdfreport(PDFTemplateView):
    template_name = "viewpdf.html"

    def get_context_data(self, **kwargs):
        return super(viewpdfreport, self).get_context_data(
            pagesize="A4",
            title="Test!",
            **kwargs
        )

here is my viewpdf.html

<table id="t01" >
<tr>
<!--<th><input type="checkbox" id="test"></th>-->
  <th>First Name</th>
  <th>Last Name</th>
  <th>Position</th>
  <th>Department</th>
  <th>Month </th>
  <th>Year</th>
  <th>Total leave consume</th>
  <th> Current Leave Entitlement</th>
   <th>Holidays</th>
   <th>Weekend</th>
   <th> Leave outstanding Balance</th>
   <th>Leave current Balance</th>
 
 
</tr>
{%for a in govstaff%}
<tr>
<!--<td><a href ="#"><input type="checkbox" onClick="parent.location='#'" > </a> </td>-->
<td>{{a.first_name}}</td>
  <td>{{a.last_name}}</td>
  <td>{{a.position}}</td>
  <td>{{a.department}}</td>
  <td>{{a.month}}</td>
  <td>{{a.year}}</td>
  <td>{{a.total_working_days}}</td>
  <td>{{a.leave_entitlement}}</td>
  <td>{{a.holiday}}</td>
  <td>{{a.weekend}}</td>
  <td>{{a.leave_outstanding_balance}}</td>
  <td>{{a.leave_current_balance}}</td>
 


  </tr>
{%endfor%}
</table>


this function is a view from a different app(view.py)
def govoffice(request):  govstaff=newleave.objects.filter(department="GOV",department_head_authorization="Approved")
    return render(request,'viewpdf.html', locals())

Have you validated that there is actual data in the govstaff variable within your template? Nothing is going to show up if it is an empty variable or doesn't exist in your template context.

While I'm not familiar with the package you're using, I suspect you need to add the govstaff variable to your context within the get_context_data() method in your view class. Otherwise your template has no idea what data you are trying to display.

Hi James,

Yes i have validated that there is  data in the govstaff variable. when i add govstaff to context within the get_context_data() i am getting the error non-keyword arg after keyword arg. Is there are other ways to generated pdf reports on Django?

Cheers,

How are you adding the govstaff variable in the get_contexr_data method? Can you post what you tried? You shouldn't be getting an error like that. Are you trying to do it as part of the super() call?

As far as alternatives go, ReportLab is pretty popular with Django, to the point where it is on the official docs:

You need to add the get method this:

 def get(self, request, *args, **kwargs):

    """
    Handles GET request and returns HTTP response.
    """
    context = self.get_context_data(**kwargs)
    #data: dic, array, etc.
    values = [1,2,3,4,5]
    # add the data in the context 
    context["values"] = values

    return self.render_to_response(context)

Cheers,
