HowTo¶
Tryton¶
Change Model Fields¶
If the fields of a model need some changes, you first might want to try to update the current database (if possible) until you are satisfied.
Nevertheless, always test a rebuild from scratch before a commit. Of course you could also skip the updating part, but a complete db setup needs more time.
Update database¶
Start the services once:
$ docker-compose up
While you are coding, apply changes to the database with
exec
(exec
executes the command on the running container instead of starting a new one, so it is faster):$ docker-compose exec erpserver db-update
Fix all update/init errors until the update runs successfully.
Watch the logs for warnings, but be aware, that sometimes there is none - e.g. if you deleted a field/relation but still use it somewhere else,
the database will still contain that table/column and you won't notice the error until a complete rebuild of the database.Run the tryton tests for the collecting_society model to test the views and depends:
$ docker-compose exec erpserver service-test
Restart the tryton client with cache disabled and test the views and fields of the model (read/write):
$ tryton -d
Rebuild database¶
Stop the services and log into the tryton service:
$ docker-compose stop $ docker-compose run --rm --service-ports erpserver bash > pip-install
Delete and setup a new database (
production
dataset only):> db-rebuild --no-template -d production
Check the log, fix all update/init errors, until the update runs successfully.
Start a tryton (only) service on second terminal (to be able to rebuild the database on the first terminal, if neccessary):
$ docker-compose up tryton
Restart the tryton client with cache disabled (you might want to create an alias for that):
$ tryton -d
Create/Fix the tests, see HowTo
Commit
Change Model Functions¶
If you change some code within a model function, you just need to restart the tryton service for trytond to reread the function definitions:
$ tryton -d
Change XML Views¶
If you change the main XML (e.g. ./code/collecting_society/collecting_society.xml
), you need to update the database (best with exec on a running container) and restart the client. A restart of the tryton server is usually not neccessary,
$ docker-compose exec erpserver db-update
WARNING: If you have fixed view errors in the XML and it seems that the view cache is not cleared or the changes in the XML definitions are not propagated to the application,
do the following:
- Check the
name
tag in the correspondingir.ui.view
record model entries in the main XML. Thename
must correspond to a file name in theview
path, but plus ".xml". - Temporarily delete the corresponding definitions of the broken view (usually at least the record models
ir.ui.view, ir.action.act_window, ir.action.act_window.view
andmenuitem
) - Update the database:
docker-compose exec erpserver db-update
- Insert the corresponding definitions of the broken view again (undo the deletion)
- Again update the database:
docker-compose exec erpserver db-update
- Restart the Tryton Client
If you change the XML views for a model (e.g. ./code/collecting_society/view/creation_list.xml
), it is sufficient to close and reopen the view in the tryton client, if cache is disabled:
$ tryton -d
Change DB Tests¶
If you want/need to change the datasets (./volumes/shared/data/datasets
), see documentation
Errors¶
Pyramid View¶
If you encounter tryton errors in a pyramid error feedback view, you might be able to get more specific information on the error:
- Open an interactive console, where one of the following keywords are passed as parameter: fieldname, error_args
- Type that variable name into the console to find out its value, which could point towards the source of the error.
Proteus¶
Errors in proteus are sometimes cryptic. See here for English and German translations:

Tryton Views¶
- If you are not able to open several views due to errors about not finding the model name in the _pool, try
docker-compose down
. - If you change the model fields and are missing the changes, sometimes you need to
- cut out the
<field>
s within the view xml: - close/open the view
- paste the
<field>
s again and - close/open the view
- cut out the
