i have a small Django app https://bitbucket.org/kaddourkardio/kardiology to manage my patients data, and use LaTeX to output reports. It consists un a *parent* model called Patients and child models Consultation , StressEcho and so on. With LaTex this works without problems def courrier_pdf(request, pk2, pk1): entry = Courrier.objects.get(pk=pk2) source = Patient.objects.get(pk=pk1) context = dict({'courrier': entry, 'patient': source})#buffer = BytesIO()template = get_template('courrier/courrier.tex') rendered_tpl = template.render(context, request).encode('utf-8')#Python3 only. For python2 check out the docs!with tempfile.TemporaryDirectory() as tempdir: # Create subprocess, supress output with PIPE and # run latex twice to generate the TOC properly. # Finally read the generated pdf. for i in range(2): process = Popen( ['xelatex', '-output-directory', tempdir], stdin=PIPE, stdout=PIPE, ) process.communicate(rendered_tpl) with open(os.path.join(tempdir, 'texput.pdf'), 'rb') as f: pdf = f.read() r = HttpResponse(content_type='application/pdf') r.write(pdf)return r i tried with this view in order to use ConTeXT but without success def courrier_mkiv(request, pk2, pk1): entry = Courrier.objects.get(pk=pk2) cource = Patient.objects.get(pk=pk1) context = dict({'courrier': entry, 'patient': cource})# buffer = BytesIO()template = get_template('courrier/courrier.mkiv') rendered_tpl = template.render(context, request).encode('utf-8')with tempfile.TemporaryDirectory() as tempdir: process = Popen(['context', '--result', tempdir], stdin=PIPE, stdout=PIPE, ) process.communicate(rendered_tpl) with open(os.path.join(tempdir, 'textput.pdf'), 'rb') as f: pdf = f.read() r = HttpResponse(content_type='application/pdf') r.write(pdf)return r My feeling is that the problem is in the workspace since i get logfiles in the root of my app Here is log file from ConTeXT: open source > level 1, order 1, name '/home/kaddour/context/tex/texmf- context/tex/context/base/mkiv/cont-yes.mkiv' system > system > ConTeXt ver: 2018.01.04 17:37 MKIV beta fmt: 2018.1.4 int: english/english system > system > 'cont-new.mkiv' loaded open source > level 2, order 2, name '/home/kaddour/context/tex/texmf- context/tex/context/base/mkiv/cont-new.mkiv' close source > level 2, order 2, name '/home/kaddour/context/tex/texmf- context/tex/context/base/mkiv/cont-new.mkiv' system > files > jobname 'tmpy82c5j7i', input '/tmp/tmpy82c5j7i', result 'tmpy82c5j7i' fonts > latin modern fonts are not preloaded languages > language 'en' is active tex error > tex error on line 8 in file /home/kaddour/context/tex/texmf- context/tex/context/base/mkiv/cont-yes.mkiv: ! I can't find file `/tmp/tmpy82c5j7i'. l.8 } I tried this in my view os.chdirw(tempdir) just before process without success. My guess is that ConTeXT option --result= does not behave exactly like LaTeX's -output-directoryAny help is welcome i really need ConTeXT for my work and this problem is driving me mad! -- Dr YAHYAOUI Mohamed Kaddour, cardiologue -- Clinique KARDIA.
