Newb - variable returns # sign?
...veRecord::Base
has_many :inventories
end
class Inventory < ActiveRecord::Base
belongs_to :species (this is the singular and the plural, so that''s
OK)
end
My inventory_controller looks like:
def show
@inventory = Inventory.find(params[:id])
@variety = Species.find(params[:species_id])
end
and in the inventory show view:
<%= @variety %>
my out put shows all the fields from the inventory but only a pound
sign(#) where the @variety is at.
Any thoughts?

NOOB: Using locals to pass data to a SQL query
...#39;, :id =>
entry }, :confirm => ''Are you sure?'' %></td>
</tr>
<% end %>
Model:
def self.mine
find_by_sql("select entries.id, species.name,
length,species.multiplier*length as score,caught_on from entries join
species on species_id = species.id where user_id = ? order by score
DESC", myfish)
end
Basically I am trying to get the current value of session[:user].id
into the find_by_sql query. Any pointers?

find_by_sql + partials question
...now that I have find_by_sql love working for my "Top 10 List" I
want to make them a bit more DRY. Tis is what I have so far:
Model:
def self.topfish
find_by_sql["select species.name,
length,species.multiplier*length as score,caught_on from entries join
species on species_id = species.id where species_id = ? order by
score DESC LIMIT 10", species]
end
This data is spit out as part of a partial:
Partial:
<% for ling in @topfish %>
<table border ="0" CELLSPACING="0">
<tr class="<%= alternate %>">

Mixed-model with paired design & covariates
...sponse variable
- 2 model types (model_type) -> fixed effect
- 230 species (species) -> random effect
- 10 replicates/species (replicate) -> random effect
- 10 subreplicate/replicate -> observation
So I have: 10*10*230 observations/model, identified as
speciesID_replicate_subreplicate (species_ID ranging 1:230, replicate 1:10
and subreplicate 1:10)
One could think about such mixed-effect model:
my.model<-lme(fixed = accuracy_measure~model_type, random =
~1|species/replicate)
I do not expand here into model simplification nor if it is best to use lme
or lmer, YET... but here are more c...

[file_column] Problem displaying images after upload
...;1/testpic.jpg"
>>
I think this might have todo with the way I am building @entry via a
find_by_sql:
def self.mine
find_by_sql("select entries.id,entries.image,
species.name, length,species.multiplier*length as score,caught_on
from entries join species on species_id = species.id order by score
DESC")
end
Any ideas what I am doing wrong?

Apologies: example of data needing zeros-no NA values
...giving an example of the data. There actually are no NA values, so I'm not simply replacing values in the data frame. So, the number of species (and therefore abundance values) listed in each treatment differs, even though they all have the same number of plots sampled.
