The preferences model in the backend builds a composite preferences object by fetching all applicable rows from the table based on four contexts: global, repo, user_global, user_repo. These basically scope the data: preferences for any user using any repo, any user using a particular repo, a particular user using any repo, and a particular user using a particular repo. The context of the request determines which contexts get loaded and what kind of composite object gets assembled. But there is always at least a ‘global’ preference representing the abstract ‘global’ repository. In the preferences model, there’s an `init` method that takes care of creating that record at startup:</div><div class=""><br class=""></div><div class=""><a href="https://github.com/archivesspace/archivesspace/blob/05f01f83414c6daa259e72abcc38b50d9450e769/backend/app/model/preference.rb#L7-L34" class="">https://github.com/archivesspace/archivesspace/blob/05f01f83414c6daa259e72abcc38b50d9450e769/backend/app/model/preference.rb#L7-L34</a></div><div class=""><br class=""></div><div class="">So the frontend controller safely assumes that there is always one context preference for `global` and expects it to be on the json payload. In your plugin, you don’t have the `init` logic so that’s not a safe assumption. You could either add something similar, or just tweak the frontend controller if the concept of ‘global’ plugin_settings doesn’t make sense in your case.</div><div class=""><br class=""></div><div class="">Brian</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Oct 15, 2015, at 5:49 PM, Carlos Lemus <<a href="mailto:carlos.lemus@unlv.edu" class="">carlos.lemus@unlv.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Hello Brian,<div class=""><br class=""></div><div class="">Thank you for your recommendations, they've helped out a lot.
