[dataimport] backout 6947201033be (related to #2788402)
(and add a try: except to cache the intended error)
The problem actually comes from the ``MassiveObjectStore``
in the ``dataio`` cube, so it should be corrected there.
Here, we only protect it with a ``RuntimeWarning`` so that
the user can see the problem.
``value`` is set to ``None`` (whence to ``NULL`` from
a database standpoint), so that the data can be nevertheless
inserted in the database. However, only the keys present in
``row`` are actually non-'``NULL``'.
The real solution is to work out the issue in ``MassiveObjectStore``
directly.
The current try/except should only be a temporary hack.
CSS Coding Standards
--------------------
(Draft, to be continued)
:Naming: camelCase
Indentation rules
~~~~~~~~~~~~~~~~~
- 2 espaces avant les propriétés
- pas d'espace avant les ":", un espace après
- 1 seul espace entre les différentes valeurs pour une même propriété
Documentation
~~~~~~~~~~~~~
Please keep rules semantically linked grouped together, with a comment about
what they are for.
Recommendation
~~~~~~~~~~~~~~
- Try to use existing classes rather than introduce new ones
- Keep things as simple as possible while in the framework
- Think about later customization by application
- Avoid introducing a new CSS file for a few lines of CSS, at least while the
framework doesn't include packing functionalities
