* The base model requires a value here
* But we aren't using one; so there's none on the form
* This change supplies a custom enumeration that's specific for this
particular model, which has one value, which is a default value,
which simply says that the field is N/A
* This does mean that when viewing or reviewing the proposal one sees
the Target Audience field, but it will say N/A.
* Testing has shown that this does not affect the other types which
descend from the base Proposal class; they still use the default
enumeration.
NB: all the proposal sections for the miniconfs here are set to open
on 2017-11-01. To make them available sooner, visit
/admin/symposion_proposals/proposalsection and change the start date.
We need to have people who are submitting a miniconf proposal agree to
releasing the material. The easiest way to do this is to just make it a
proposal like the other two types. We don't have audience type for
miniconf, instead of deleting it just have a default - it's easier.
WARNING: This requires a real migration to be performed before use.
Update the recording and materials release to say Linux Australia, not
Pycon Australia. This generates a migration because the model text has
change - but also because in the 0001_initial migration it appears that
this help text is stored as a byte string.
This is a bit weird, but realistically running this migration is not
going to cause us any problems so just add it so we don't end up
fighting django along the way.
