I am currently trying to print financial reports with my web app - this needs to happen by the click of a button. When I click the button, however, the app only prints 1 document (the first one) I don't understand what this could be as there are 2 different returns for each if statement that re-direct to 2 different .HTML pages

This is what I have tried at the moment:

import tempfile
def printReports(request , reports_pk):
    pkForm = get_object_or_404(SettingsClass , pk=reports_pk)

    complexName = pkForm.Complex
    if pkForm.Trial_balance_Year_To_Date == True:
        ### Printing Trial Balance PDF
        response = HttpResponse(content_type= 'application/pdf')
        response['Content-Disposition']= 'attachment; filename=TrialBalance'   \
            str(datetime.now())   '.pdf'
        response['Content-Transfer-Encoding'] = 'binary'

        content =  {"x_AlltrbYTD":x_AlltrbYTD , 'xCreditTotal':xCreditTotal , 'xDebitTotal':xDebitTotal , 'complexName':complexName , 'openingBalances': openingBalances ,'printZero':printZero , 'printDesc':printDesc , 'printAcc':printAcc}
        html_string=render_to_string('main/reports/trialBalanceYear.html' , content)
        html=HTML(string=html_string)

        result=html.write_pdf()

        with tempfile.NamedTemporaryFile(delete=True) as output:
            output.write(result)
            output.flush()

            output.seek(0)
            response.write(output.read())

            return response

    if pkForm.Trial_balance_Monthly == True:
       
        ### Printing Trial Balance PDF
        response = HttpResponse(content_type= 'application/pdf')
        response['Content-Disposition']= 'attachment; filename=TrialBalanceMonthly'   \
            str(datetime.now())   '.pdf'
        response['Content-Transfer-Encoding'] = 'binary'

        content =  {"xtrbMonth":xtrbMonth , 'xCreditTotalM':xCreditTotalM , 'xDebitTotalM':xDebitTotalM , 'complexName':complexName , 'printZeroM':printZeroM}
        html_string=render_to_string('main/reports/trialBalanceMonthly.html' , content)
        html=HTML(string=html_string)

        result=html.write_pdf()

        with tempfile.NamedTemporaryFile(delete=True) as output:
            output.write(result)
            output.flush()

            output.seek(0)
            response.write(output.read())

    else:
        printTrialBalanceMonth = False

The program only prints what the first if-statement shows and doesn't print the second .pdf document. Does anyone know what might be causing this?

CodePudding user response：

You are using return in your first if block.

Django generates a response and the code below return never runs (by the way it returns nothing, so you won't have a response even if pkForm.Trial_balance_Monthly == True.

Modern IDE, such as Pycharm will show you a colored warning here, but if you are not using such IDE you can trace what's happening in your code using a debugger.

To make such interaction as you've described (only one button and 2 reports) you need:

1. Make 2 different endpoints for 2 reports
2. Write JS handler that listens to button's click and call for a 2 enpoints. Handle response as usual.

Alternative scenario:

Make a temp zip file with two reports and create a response with only one zip file. Every OS has unzip feature, so your user will find this very intuitive. Here is zipfile documentation
