Also added is_default_accessible() to Thread class as its owner may be a
Topic with forum access restrictions or public main content (like
Program)
[MIGRATION] This commit contains a new version of the schema. /!\ This
migration breaks all attachments
Each object has a .delete() which removes it and its owned subcontents.
This delete() unfortunately has to commit the database session because
circularly-dependent objects (such as a thread and its top comment)
cannot be deleted together; two commits are needed.
This changes fixes#25 by restructuring the forum models in a way
compatible with the polymorphic behavior of SQLAlchemy. Incidentally,
the new form turns out to be more appropriate for our use than the
polymorphic one originally used.
The migration for this task is non-trivial because the Thread class was
created with a foreign-key id which thus had no auto-increment or
associated sequence. The most reliable way of getting it back was to
recreate the table because SQLAlchemy ony performs automated sequence
introduction at table creation time. Four separate migration files
perform the whole change.
This commit also adds views and forms to create topics, and the
boilerplate for an advanced markup editor that can be used as a widget.
First migrate without the foreign key to create the tables, then add the
foreign key in a second migration.
Also removed unneeded imports that caused dependency cycles.
Minor "style" edits with the ambiguous use of super and unnecessary
db.Model inheritance.
