Hello Everyone,
If you happened to install Arches v4.0b3 and created a project using the
"arches-project create" command and want to keep that project then the
following instructions are for you!
The first thing to do is download the attached python script file
(update_project.py).
The script file takes the path of the project root as the only positional
argument. Example:
*python update_project.py
~/Documents/projects/GCI/arches_v4/myproject/myproject*
Running this script will do the following:
1. Add an empty arches.log file in root.
2. Create a directory called logs in root if it doesn't exist and add an
empty file called 'resource_import.log'.
3. Create a file in root called 'proposed_settings.py' which is a copy
of the project's original settings.py file plus the new v4 settings.
4. Download the bower.json file to root and name it 'proposed_bower.json'
Once you run this file you just need to:
1. Review 'proposed_settings.py' and either rename it 'settings.py' or
copy its contents to 'settings.py'.
2. Rename 'proposed_bower.json' to 'bower.json' or copy its contents to
'bower.json'.
Finally, *MAKE A BACKUP OF YOUR DATABASE**,* then cd into the root of the
project and then run the following commands from an activated virtual
environment:
1. pip install arches --upgrade
2. python manage.py migrate
3. bower install (from the directory where the bower.json file exists)
4. bower prune
Go into your /templates directory and remove the following files, unless
you've modified them, in which case you'll need to get new copies of those
files from here (
https://github.com/archesproject/arches/tree/4.0.0/arches/app/templates)
and apply your modifications to those new files:
1. base-manager.htm
2. login.htm
Now start Arches.
1. open a browser (Google chrome)
2. login to Arches as 'admin'
3. navigate to /settings
4. update your Mapbox API Key (Go to Map Settings –> Mapbox API) (the
old location for the key is in settings.py)
For further settings help go here:
http://arches4.readthedocs.io/en/latest/initial-configuration/
That's it! Arches v4 should be running properly!
If you have any further questions please post them to the forum and we'll
try to answer them as soon as we can.
Cheers,
The Arches Team
