このコードがこの NoMethodFound エラーを作成している場所がわかりません。役立つ提案があれば本当に知りたいです。
エラーメッセージは次のとおりです。
NoMethodError in UploadsController#create
私のモデルの関連部分は次のようになります。
named_scope :by_name, lambda { |marker_name|
{:conditions => ["marker_name = ?", marker_name]}}
def self.parse_file(file)
FasterCSV.foreach(file.path,:headers=>"first_row", :col_sep=>"\t") do |row|
if $header_row == 1
$markers = {} # define global hash for marker id lookup
$markers_arry = [] # define global array for marker names
get_markers(row)
$header_row = 0
# done with header row; loop back to beginning for first row of actual data
next
end
...
def self.get_markers(row)
offset = 8 # this was determine by trial-&-error
i = 0
for col in row
i += 1
if i < offset
next
end
this_marker = Marker.by_name(row[col])
$markers[row[col]] = this_marker.id # associate the marker_name with its id
$markers_arry[col] = row[col]
end
end
トレースは次のようになります。
