Ruby Usergroup Hamburg - September 2016

gehostet durch Peter Schröder bei Jimdo (, 14.09.2016 um 19:00

This time we are meeting again at the new Jimdo event location the Jimdo Haus.

If you would like to propose a talk, get in touch.

Spontaneous contributions are welcome as well!



Building complex queries with the Active Record Query Interface (HH)

The Active Record query interface is a great way to build complex queries in a simple, (mostly) SQL-agnostic way.

In this talk I would like to describe how we are constructing a complex multi-parameter query at Study.EU to retrieve study programmes from the database based on a search initiated by the user.

The parameters include name, academic level, country, subject, tuition fees in different currencies, duration and the required level of English. Hence the queries include string and integer comparison, ranges, arrays, joins and basic arithmetic.

This talk will be accessible to Rails novices but also include advanced tweaks for seasoned Rails devs.

Behavior testing at Jimdo

This talk will cover how we behavior-test the Jimdo website builder application.

We will take a look at gems like cucumber and watir-webdriver and how we use those for testing our UI, also addressing how we try to keep the tests stable and the test execution time at a bearable level.
