Hi, thank you for your response It seems that there is an error when I asked for help in google translation i have a form two views: plot(request) who return an httpresponse and showgraph(request) who return a template (affichage.html) <form action = "plot/image.png "...> call the function plot(request) in my views and return an httpresponse with this url (r $' ^plot/ image.png ', 'plot ') the response is just an html file where python write the image. This works when i call directly the function plot(request) and ask to return an httpresponse. The 500 error is when I try to go through show_graph function to display the response in a template (<form action = "show_graph/ image.png "...> with url (r $' ^show_graph/image.png ', 'show_graph ') : in this template I put just a link to the image, as explained in the documentation for Django I think the error is in image.png GET, a python syntax error but I can not think where (I do not know how to retrieve the trace of a 500 error in django, I installed django debug toolbar) it seems that python can not write the file with the image ..the content type? ..I don't understand, .this second view works when i ask an httpresponse instead of the template At this time i can run everything by saving the image on the server disk but it is not an option in production, would require that all things be done in memory in an HttpResponse
