AgDSS

Django based Agricultural Decision Support System (AgDSS) for robotic sampling in precision agriculture. Please note that this documentation is incomplete and may be out of date.

##Setup

  1. Required software:
  • Python2 (Python3 untested) with packages NumPy, Pillow, Wand, and django-adminplus
  • Django* < 1.10 (django 1.10 no longer allows you to specify urls as string, http://stackoverflow.com/questions/38744285/django-urls-error-view-must-be-a-callable-or-a-list-tuple-in-the-case-of-includ)
    • pip install django==1.9
  • Postgres (or other database, though using another database requires changing code). Set port to 5432 (or change code to reflect chosen port). (Setup information: here)
  • psycopg2 (required for Postgres)
  • ImageMagick (ImageMagick 6.7.7-10 Q16 and ImageMagick-6.9.4 Q16 are known to be working and compatible versions) (Tarball for previous versions can be found here)
  1. Clone this repo (and navigate to it).
  2. Create a (Postgres) database called agdss which has a user aguser with a password aguser (with all permissions). To change these configurations, see DATABASE in aguser/settings.py. The easiest way to do this is through a GUI manager like pgadmin3. However, it can be done via the Unix terminal.
  • If on Windows, one may be required to create a Firewall inbound rule allowing traffic on port 5432 as it is closed by default. This may not be necessary, but attempt if there is a problem.
  • To do this in the terminal, follow the setup information here. Afterwords, to create the user, run sudo -u postgres psql to enter the postgres prompt. There, run CREATE USER aguser WITH PASSWORD 'aguser'; followed by GRANT ALL PRIVILEGES ON DATABASE "agdss" to aguser;.
  • DB setup on MacOSX: psql postgres CREATE DATABASE agdss; CREATE USER aguser WITH PASSWORD 'aguser'; GRANT ALL PRIVILEGES ON DATABASE "agdss" to aguser;
  1. Run python manage.py migrate --settings=agdss.settings.prod to create the tables in the database.
  2. To create admin credentials (required to access /admin), run python manage.py createsuperuser and enter the requested information.
  3. Create a new settings file under '\agdss\settings'. Copy the settings from prod.py and change the STATIC_ROOT to point at a local directory you want the server to access.
  4. TEMPORARY: Set STATIC_ROOT to parent directory of images (in agdss/settings.py).
  5. TEMPORARY: Place all images directly in directory named tag_images which is a child of the STATIC_ROOT directory. (The images MUST be in a subfolder for this to work!)
  6. To start server, run python manage.py runserver --settings=agdss.settings.[your settings].
  7. The webapp can then be accessed at http://localhost:8000. For a list of available pages, see the file agdss/urls.py.

##Adding Images Send a POST to /webclient/addImage with parameters:

  • path: location of image (not including image name itself. E.g. '/home/self/image-location/'). REQUIRED
  • image-name: name of image REQUIRED
  • category: Category of the image (e.g. 'apple'). REQUIRED
  • description: A description NOT REQUIRED
  • source_description: Description of image_source. NOT REQUIRED Note that this POST request can be sent from anywhere. In the future it will require some method of authentication.

##TODO

  1. Update paths to work from config file
  2. Category selection menu rather than field in tagging page
