Commands examples

If the namespace is not used then the commands will perform on top of the default database. bundle exec rake db:create bundle exec rake db:migrate

By using the namespace we are going to use all the configuration for our alternate DB. bundle exec rake store:db:create bundle exec rake store:db:migrate

Number to Ordinal

See full kata at codewars

Finish the function numberToOrdinal, which should take a number and return it as a string with the correct ordinal indicator suffix (in English). That is:

• numberToOrdinal(1) ==> '1st'
• numberToOrdinal(2) ==> '2nd'
• numberToOrdinal(3) ==> '3rd'
• numberToOrdinal(4) ==> '4th'

vimdiff cheat sheet

##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)
