Hi all, recovering Perl addict here to ask a hopefully easy question.
First off, as someone completely new to Rails and subsequently Hobo, I
want to thank you for a very interesting and usable system for rapidly
creating a website!
Accolades aside, some of the magic that hides the inner workings,
hides them a bit too well for someone trying to learn, hence my
question.
I'm running Ruby 1.9.1, Rails 3.0.7, and, I think, the latest version
of Hobo. I'm trying to port a simple Perl application over as my
first project. The old site uses a flat file that uses server names
generated by the website, and another that holds the location
information (city airport code, description, and last used-number).
In moving it over to Hobo, my db tables look like:
#The nearest AirPort Code of the location in which the server lives
apc
fields do
name :string, :required, :limit => 3
description :string
timestamps
end
has_many :dc_locs, :dependent => :destroy
children :dc_locs
#The Datacenter location
dc_loc
fields do
name :string, :required, :limit => 1
description :string
timestamps
end
belongs_to :apc
has_many :servers, :through => :server_assignments, :accessible =>
true
has_many :server_assignments, :dependent => :destroy
children :server_assignments
children :servers
#The Servers list
server
fields do
name :string
user_ip :string
svr_desc :string
timestamps
end
#An assignment list to put them all together
server_assignment
fields do
timestamps
end
belongs_to :server
belongs_to :dc_loc
So far so good, everything is playing well together.
The server names have the apc imbedded in them and a 1 digit dc
location identifier.
My main question is:
In the form that I have that edits the dc_loc (location), I'm trying
to assign server to the dc_loc and I get the select-many list but I
want to filter that 1200+ list down to just the servers that have the
apc for that dc_loc in the name.
My application.dryml has:
<extend tag="form" for="DcLoc">
<old-form merge>
<field-list: fields="name, description, apc, servers">
<servers-view:>
<select-many options="&@SList"/>
</servers-view:>
</field-list:>
</old-form>
</extend>
And my dc_locs_controller.rb looks like spaghetti - I've tried many
things
#def Svrs
# @SList = Server.apply_scopes(
# :search => [this.apc_id, :name]
# )
#hobo_index @SList
#end
def edit
#hobo_show do
@sns = find_instance
@SList =
@SList = @sns.servers.where(["name
like ?", :apcs_name[this.apc_id]])
#@sn = Server.name_contains(:apcs_name[this.apc_id])
#@sn = Server.apply_scopes(:name_contains =>
params[:name_contains])
#@SList = @ss.to_a
# end
end
end
the latest one gets an error : undefined method `apc_id' for
nil:NilClass
I've gone through all the tutorials and the recipes on the hobocentral
site and searched this list until cross-eyed, but each time I try the
different solutions I'm still getting the same full list (or none at
all). Each of the tutorials and recipes have been very helpful, but
not complete when it comes to controlling the exact way to insert
custom sql code. I've tried passing name_contains scopes and still
get the full list with a message in the console that :name_contains is
being overwritten (probably due to incorrect syntax).
Any assistance would be greatly appreciated. Even if you point me to
another place to learn Rails better before I continue.
Regards,
M
