Rake db:seed problems

Hello All,

I’m having trouble using the new rake db:seed function. I initially
built my app in Rails 3.2.2 but have updated and re-frozen the new
version (3.2.4) which is supposed to have the new data seeding
function. I created a seed.rb file at db/seed.rb that looks something
like this:

BuildingClass.create(:name => “Residential Zones”, :land_used =>
1 )
BuildingClass.create(:name => “Universities”, :land_used =>
2 )
BuildingClass.create(:name => “Intelligence Centers”, :land_used =>
3 )
BuildingClass.create(:name => “Research Centers”, :land_used =>
2 )
BuildingClass.create(:name => “Government Centers”, :land_used =>
2 )
BuildingClass.create(:name => “Tank Factories”, :land_used =>
5 )
BuildingClass.create(:name => “Plane Factories”, :land_used =>
5 )
BuildingClass.create(:name => “Shipyards”, :land_used =>
5 )
BuildingClass.create(:name => “Fortifications”, :land_used =>
2 )

WeaponType.create(:weapon_branch_id => 1, :offense_base =>
3.0, :defense_base => 9.0, :weapon_type_name =>
“Tanks”, :description => “Defensive Ground Unit”)
WeaponType.create(:weapon_branch_id => 1, :offense_base =>
12.0, :defense_base => 3.0, :weapon_type_name =>
“Artillery”, :description => “Offensive Ground Unit”)
WeaponType.create(:weapon_branch_id => 2, :offense_base =>
3.0, :defense_base => 10.0, :weapon_type_name =>
“Fighters”, :description => “Defensive Air Unit”)

Whenever I try to run the command rake db:seed it appears to run with
no errors but doesn’t give any feedback and does not modify the DB.

Is anybody able to help?

Just a note, you can restructure this to make it a little more DRY. I
find this easier to manage in the long run, particularly if I may need
to add more later.

buildingclasses = [
{:name => “Name”, :land_used => 1},
{:name => “Name 2”, :land_used => 2}
// etc
]

puts “adding building classes”
buildingclasses.each do |b|
BuildingClass.find_or_create_by_name(b)
end

Have you tried seeding with rails unfrozen? Wondering if you can
determine whether that’s the problem, or if it’s elsewhere.

Yeah, I thought of combining them into something like you suggested,
but wanted to get them working in the simplest form before I tried
complicating the file.

I’ll try running it with an unfrozen rails later tonight. Don’t have
access to an updated rails install right now…thus the frozen
rails :slight_smile:

Tried it with an unfrozen rails install…still won’t work. I also
stripped most of the seed data out of the file and condensed the
information for the one model I left in. This is the file in it’s
entirety:

buildingclasses = [
{:name => “Commercial Zones”, :land_used => 1 },
{:name => “Residential Zones”, :land_used => 1},
{:name => “Universities”, :land_used => 2 },
{:name => “Intelligence Centers”, :land_used => 3 },
{:name => “Research Centers”, :land_used => 2 },
{:name => “Government Centers”, :land_used => 2 },
{:name => “Tank Factories”, :land_used => 5 },
{:name => “Plane Factories”, :land_used => 5 },
{:name => “Shipyards”, :land_used => 5 },
{:name => “Fortifications”, :land_used => 2 }
]

puts “adding building classes”
buildingclasses.each do |b|
BuildingClass.find_or_create_by_name(b)
end

well…i feel like an idiot…the blog that I googled and found the
instructions for using this on said to use db/seed.rb. just changed it
to seeds.rb and it worked beautifully.
