Read A Local File In Django

I'm quite stuck on this one! I am writing a Django view that reads data from an external database. To do this, I am using the standard MySQLdb library. Now, to load the data, I mu

Solution 1:

Keep the file in django project root and add the following in the settings.py file.

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))

Then in the view do this.

import os
from django.conf.settings import PROJECT_ROOT

file_ = open(os.path.join(PROJECT_ROOT, 'filename'))

Update:

In newer Django versions BASE_DIR is already defined in the settings.py file. So you can do the following.

import os
from django.conf import settings

file_ = open(os.path.join(settings.BASE_DIR, 'filename'))

Solution 2:

For this use, I'd put it in the settings module. In settings.py, add e.g. MY_LONG_QUERY = 'from FOO select BAR...'. Then, in your view just load it from the settings like so:

from django.confimport settings
settings.MY_LONG_QUERY

But, this doesn't really answer your question. Assuming permissions and all are correct, keep a reference to your project root in your settings like this:

ROOT_PATH = os.path.split(os.path.abspath(__file__))[0]

And then again in your view, open your file like so:

from django.conf import settings

defread_from_database(request):
    f = open(os.path.join(settings.ROOT_PATH, 'myfile.db'))
    # Do something with f
