Jan Provaznik	0fc9f9d3e7	Add version 4.2 to all existing migrations ... DB schema generated by a migration may look different in rails 4 and 5 (because rails 5 may use different default values). For this reason it's important to explicitly set for which rails version a migration was written for. See https://stackoverflow.com/questions/35929869/activerecordmigration-deprecation-warning-asks-for-rails-version-but-im-no/35930912#35930912	2018-11-22 13:18:28 +01:00
Yorick Peterse	aac1de46c9	Use a specialized class for querying events ... This changes various controllers to use the new EventCollection class for retrieving events. This class uses a JOIN LATERAL query on PostgreSQL to retrieve queries in a more efficient way, while falling back to a simpler / less efficient query for MySQL. The EventCollection class also includes a limit on the number of events to display to prevent malicious users from cycling through all events, as doing so could put a lot of pressure on the database. JOIN LATERAL is only supported on PostgreSQL starting with version 9.3.0 and as such this optimisation is only used when using PostgreSQL 9.3 or newer.	2017-08-10 17:45:49 +02:00
