DEV: enable frozen string literal on all files This reduces chances of errors where consumers of strings mutate inputs and reduces memory usage of the app. Test suite passes now, but there may be some stuff left, so we will run a few sites on a branch prior to merging 2019-05-02 18:17:27 -04:00			`# frozen_string_literal: true`

Fix all the errors to get our tests green on Rails 5.1. 2017-08-31 00:06:56 -04:00			`class SplitPublicInGroups < ActiveRecord::Migration[4.2]`
FEATURE: Add group settngs to allow users to leave a group freely. https://meta.discourse.org/t/split-join-leave-freely-setting-on-groups/65565 2017-07-27 22:37:10 -04:00			`def up`
			`add_column :groups, :public_exit, :boolean, default: false, null: false`
			`add_column :groups, :public_admission, :boolean, default: false, null: false`

DEV: remove exec_sql and replace with mini_sql Introduce new patterns for direct sql that are safe and fast. MiniSql is not prone to memory bloat that can happen with direct PG usage. It also has an extremely fast materializer and very a convenient API - DB.exec(sql, params) => runs sql returns row count - DB.query(sql, params) => runs sql returns usable objects (not a hash) - DB.query_hash(sql, params) => runs sql returns an array of hashes - DB.query_single(sql, params) => runs sql and returns a flat one dimensional array - DB.build(sql) => returns a sql builder See more at: https://github.com/discourse/mini_sql 2018-06-19 02:13:14 -04:00			`DB.exec <<~SQL`
