Requirements to Partition a Sample


I’ve just installed Senaite 2.2.0 and I was interested in the partitioning functionality. Our situation is that we will receive bags of samples that need to be tested separately, but the results need to be reported by bag.

I followed the quick start guide for Senaite 2.2.0, down to: and I’m not seeing a button or prompt for partitioning samples. Perhaps there is an option to activate? Are there requirements to satisfy for a sample to be partitioned?

Hi @cwisch

Once your select a sample from your samples list, you should see a create partitions button at the bottom of the page

Hi @ronaldm,

Thanks for posting the screenshot, my install of Senaite does not look like this, I have all the options except “create partitions”.

Should “create partitions” show up for every sample, or are there certain contexts that it shows up? For example only certain types of units?

Thank you,


Hi @cwisch

Which version of Senaite Core and Senaite LIMS are you on?

Your problem might be as a result of:

I came across this github issue as well and I had trouble making sense of it. When I’ve been making samples I have been signed in as the admin user, so I wouldn’t think I would be seen as a “client” of the organization. But perhaps that is the case?

As for versions, I appear to be on 2.2.0 for everything:

Quick update, I’ve installed Senaite multiple different ways, and I finally restored the “create partitions” button, by “unpinning” senaite.lims to senaite.core 2.2.0. I used the current build of senaite.core as development egg, and removed senaite.core=2.2.0 from the of senaite.lims.

The result is that the analyses portion of the samples break in a myriad of ways. The most obvious is the analyses portion of the sample breaks:

So perhaps going back to version 2.1.0 is the answer since partitions seem to have issues in version 2.2.0.

@ronaldm Downgrading to 2.1.0 and now it appears to behave as shown in the documentation.
