Minor changes and a question

[xispa]

Not sure about this change, but this condition is also used in https://github.com/senaite/bika.lims/pull/480/files#diff-05737f388606e64fa9543e7eea467c36R680 . So, if this changes here, I guess this change must be applied in Line 680 too. Maybe there are other places where this condition is used?

If I understand correctly, with len(value) > 1 we prevent the system to do searches if the search term does not have at least 2 characters? Can you confirm @Espurna

[Espurna]

Indeed, think about a case where we have '1' and '0' as True/False indicators. In my opinion this conditional should check whether there is data.

Good point

I'd add the review_state in which the printed option makes sense (published) instead of removing it:

query['getPrinted'] = 0
query['review_state'] = ['published',]

for cookie name, better use a constant outside the class like:

FILTER_BY_DEPT_COOKIE_ID = 'filter_by_department_info' 

Also, encapsulate this block of code like:

def _get_filter_by_department_uids(self):
    if not self.context.bika_setup.getAllowedDepartmentFiltering():
        return []
    cookie_dep_uid = self.request.get(FILTER_BY_DEPT_COOKIE_ID, None)
    if not cookie_dep_uid:
        return []
    return cookie_dep_uid.split(",")

def _fill_department_uids(self, query=None):
    if not query or not isinstance(query, dict):
        return
    uids = self._get_filter_by_department_uids()
    if len(uids) == 0:
        return
    query['getDepartmentUIDs'] = {"query": uids, "operator": "or"}

Then, you can simply do the following:

self._fill_department_uids(query)
