Nested locations

[Sri Prasanna]

Hi,

We followed the steps in this guide to implement nested locations. But looks like migration for adding "tree_parent_id" column to locations_location table is missing and this is raising "column locations_location.tree_parent_id does not exist" when we query for Location.objects.all()

Please let us know how can we fix this issue and here is the installed apps list.

With the latest RMS, there have been a number of changes with nested locations. I personally followed advice in the docs where I subclass location models and do all mptt work to the models. I too had a similar error months back.

Victor,

Does this mean RapidSMS's nested location module cannot be used at the moment? Adding location subclass is not an option for us since we need to store hierarchical location information(using location type and location).

With unicef's code, you need some hard work with the migrations. There are just many dependencies that need to be fixed to match the latest. Lots of work, but doable. I tried using a locations fixture from an old UNICEF project, this failed coz of that error,

Victor,

Here is the migration we used to fix this issue. It should be documented/patched somewhere so that other developers can avoid this issue in future.

Sri, could you please open an issue (https://github.com/rapidsms/rapidsms/issues/new) and include how you solved the problem? Then others could more easily find the solution, and maybe someone will be able to fix it in the code at some point.

Thanks!
