Bug in bitbucket team project?

Client moved to its own repository (ics-inventory-client)

Add button to return to main index

ics_id, serial_number, manufacturer_id and model_id should not change.
Repeating them in the history table takes space for nothing.

We are only interested in tracking the status, location and parent.

- catch IntegrityError on patch
- disable autoflush (IntegrityError was raised before commit due to
autoflush)

Pass ?qrcode=true as query string

Fix default button issue on login page

- use same postgres container for dev and test
  (create 2 different databases)
- use docker-compose.override.yml to avoid duplication
- ignore more files not needed in the docker image

By default docker-compose reads both docker-compose.yml and
docker-compose.override.yml.
In docker-compose.override.yml we mount the current directory as
a volume for development.

To test the image we only use docker-compose.yml:
- don't force port 5432 to the outside world to avoid conflict
- do not mount the current directory

- change label (jenkins-slave should have docker-compose installed)
- only push when the current commit is a tag

Can use:

  -  /api/items?serial_number=123456
  -  /api/items?location_id=1

This allows a client to login only once a day.

We might want to decrease that and look into refresh token.
But this looks overkill for our use case.

- add more tests
- patching an item update children location and status
- setting the parent on an item updates the location and status with the
  parent ones

This can be done via the Admin interface but this latter shall be
restricted to admin users. This simple page allows the group "create"
to easily add new Manufacturer, Model or Location.

To make it easier, different decorators are created
depending if the user logged in using a JWT (API)
or cookie (web UI).

Clean code at te same time.
The macro from flask-bootstrap already takes care of everything.

- update flask-bootstrap
- update datatables to v1.10.15 for bootstrap 4 support

The CIText type is not known by Flask-Admin and was not rendered.
A custom model converter is required.
