Comment on Using ActiveRecord’s to_xml to produce custom xml including deep level associations by justin

justin — Sat, 17 Dec 2011 12:57:18 +0000

With the deep_xml method example, children aren’t wrapped in a tag, so I had to define the method like:

def deep_xml(builder=nil)
to_xml(:builder => builder) do |xml_builder|
xml_builder.children { |xml|
children.each{|child| child.deep_xml(xml)}
}
end
end

THANK YOU! I was running into dropped/close MySQL connection when I was forking as the connection was getting cloned.

Using ActiveRecord::Base.remove_connection seems to have solved this issue.

ERROR: function postgis_full_version() does not exist
LINE 1: SELECT PostGIS_Full_Version();

HINT: No function matches the given name and argument types. You might need to add explicit type casts.
postgres=#

If I run (newly):
psql -d geoespacial -f /usr/share/pgsql/contrib/postgis-1.5/postgis.sql

1. What is the default journal mode if the “journal_data” | “journal_data_ordered” | “journal_data_writeback” are not specified? Is it distro specific? If so, how do I find out?

Is the /etc/fstab mount option “data=writeback” redundant if “journal_data_writeback” is set in the superblock?

I had the same problem of those PostGIS .sql files missing, MY SOLUTION:

sudo apt-get install postgresql-contrib

That is, my whole /contrib directory was missing, and this was why. When I installed postgresql-contrib and the PostGIS, everything was OK.
