"Cannot read property 'XXXXXX' of null" #9

Closed jacobq closed 6 years ago

jacobq commented 6 years ago

I'm not sure what I'm doing wrong. The docs make it sounds like all that is needed to use with ember-data is to install and create an adapter, but that didn't work for me. I also tried calling indexedDb.setupTask.perform(); when the application (controller) is initialized.

Is this a bug (doesn't work with ember-data) or am I doing something wrong?

Repro repo here (run yarn && ember s)

Ref #3

It seems that you haven't configured your database. You need to add a indexeddb-configuration service, like explained here:

https://mydea.github.io/ember-indexeddb/docs/classes/IndexedDbConfiguration.html

You will need to configure a table per model for the ember data adapter to work.

Thanks for your reply. Perhaps for someone who is familiar with the workings of IndexedDB or this addon the docs are sufficiently clear. However, I have no idea how to interpret statements like this one:

"Overwrite the mapTable property & add versionX properties to fit your application."

Overwrite with what? Coming from configuration-less back-ends like ember-localstorage-adapter this is a significant barrier to adoption.

I submitted a docs PR for your consideration because I think the current text is misleading (specifically, the word "just" implies that no other action is needed). However, before you replied I gave up and switched to ember-pouch since it was easier for me, so I am closing this issue.
