#Streamflow Prediction Tool App tethysapp-streamflow_prediction_tool

This app requires you to have the ECMWF AutoRAPID preprocessing completed separately. See: https://github.com/erdc-cm/spt_ecmwf_autorapid_process; https://github.com/erdc-cm/spt_lsm_autorapid_process

##Prerequisites:

• Tethys Platform v1.3 (CKAN, PostgresQL, GeoServer): See: http://docs.tethysplatform.org/en/1.3.0/
• RAPIDpy (Python package).

###Install RAPIDpy: For instructions, go to: https://github.com/erdc-cm/RAPIDpy.

Note: Before installing RAPIDpy into your python site-packages, activate your Tethys python environment:

$ . /usr/lib/tethys/bin/activate

##Installation: Clone the app into the directory you want:

$ git clone https://github.com/erdc-cm/tethysapp-streamflow_prediction_tool.git
$ cd tethysapp-streamflow_prediction_tool
$ git submodule init
$ git submodule update

Then install the app in Tethys Platform.

###Installation for App Development:

$ . /usr/lib/tethys/bin/activate
$ cd tethysapp-streamflow_prediction_tool
$ python setup.py develop
$ tethys syncstores streamflow_prediction_tool

###Installation for Production:

$ . /usr/lib/tethys/bin/activate
$ cd tethysapp-streamflow_prediction_tool
$ python setup.py install
$ tethys syncstores streamflow_prediction_tool
$ tethys manage collectstatic

Restart the Apache Server: See: http://docs.tethysplatform.org/en/1.3.0/production/installation.html#enable-site-and-restart-apache

##Updating the App: Update the local repository and Tethys Platform instance.

$ . /usr/lib/tethys/bin/activate
$ cd tethysapp-streamflow_prediction_tool
$ git pull
$ git submodule update

Reset the database if changes are made to the database (this will delete your old database and regenerate a new app instance id):

$ tethys syncstores streamflow_prediction_tool -r

Restart the Apache Server: See: http://docs.tethysplatform.org/en/1.3.0/production/installation.html#enable-site-and-restart-apache

Troubleshooting

ImportError: No module named packages.urllib3.poolmanager

$ pip install pip --upgrade

Restart your terminal

$ pip install requests --upgrade

Crontab Errors

Check if your server has crontab permissions: Ex:

# su -s /bin/bash apache
bash-4.2$ crontab -e
You (apache) are not allowed to use this program (crontab)
See crontab(1) for more information

If not, add the permissions in the cron.allow file.

# echo apache >>/etc/cron.allow

SELinux

If you are using a drive/folder not associated with your normal apache server locations, you may need to set SELinux to allow it. In this example, I am using a folder named /tethys

# semanage fcontext -a -t httpd_sys_content_t '/tethys(/.*)?'
# restorecon -Rv /tethys
