I need to run a C++ Program from Django Framework. In a sense, I get inputs from UI in views.py . Once I have these inputs, I need to process the input using my C++ program and use those results. Is it possible ?
Compile that C++ program to executable and call with subprocess module from python
You can use swig to create a C++ module that can be imported in python. An alternative is boost::python (but personnaly, I prefer swig).
One way of doing this would be to use os.popen. Assuming your C++ executable is in the system wide path and is named
mycpp, you would do something like:
results = os.popen('mycpp %s' % user_input).read()
However, this could get computationally expensive real fast if you're invoking this command often 'cause
os.popen basically forks off a subprocess. Also, as noted in the docs, it's been deprecated since Python 2.6 so proceed with caution.
Assuming you are on *nix, compile your C++ program and store it somewhere on your system, say /home/rishabh/myexe.
Now from your django app call the executable using commands module:
import commands status, res = commands.getstatusoutput("/home/rishabh/myexe") # status contains process status (0 for success, non-zero for unsuccesful termination) and res contains the output of the process
