rake db：seed之后不生成表

Question

当我使用rake db：seed命令时，我有一个带有大量数据的csv文件 控制台显示..

deleting old index
creating new index
starting import
20
refresh index

看起来每件事都很好但是表格甚至没有创建

我的seed.rb是

require 'csv'

puts "deleting old index"
Article.index.delete

puts "creating new index"
Article.create_elasticsearch_index

mapping = {
"id" => "id",
"artikel_nr" => "artikelnummer",
"ean_nr" => "eannummer",
"bezeichnung_1" => "bezeichnung",
"bezeichnung_2" => "bezeichnung_zusatz",
"match_code" => "matchcode",
"verkauf_me" => "mengeneinheit",
"gewicht" => "gewicht",
"lieferant_nr" => "hersteller_nummer",
"bestell_nr" => "hersteller_artikelnummer",
"produkt_gruppe" => "gruppe",
"artikel_gruppe" => "gruppe_nummer",
"produkt_hauptgruppe" => "hauptgruppe",
"rt_1" => "langtext",
"masse" => "dimension",
"einzelpreis_vk" => "listenpreis_netto"
}

count = 0
buffer = []

puts "starting import"

hersteller = Hash[CSV.read("db/red1.csv", col_sep: ',', row_sep: :auto, headers: true).map {|row| [row["lieferant_nr"], row["beschreibung"]]}]

CSV.foreach("db/red1.csv", col_sep: ',', row_sep: :auto, headers: true) do |row|
# map keys
 hash = Hash[row.map {|k, v| mapping[k] ? [mapping[k], v && v.strip.gsub("\u00A0", "")] : nil}.compact]

  # ignore NULL values
  hash.reject! {|k, v| v == "NULL"}

  # get hersteller names
  hash["hersteller"] = hersteller[hash["hersteller_nummer"]].strip.gsub("\u00A0", "")   if hash["hersteller_nummer"].present?

  # set hierarchie
  hash["hierarchie"] = if hash["hauptgruppe"].present? && hash["gruppe"].present?
                     "|" + hash["hauptgruppe"].strip + "|" + hash["gruppe"].strip
                   else
                     "|"
                   end

  # TODO: validate

  # enqueue hash
  buffer << hash

  count += 1
   if count % 1000 == 0
  Article.index.import buffer
  buffer = []

  puts count
 end
end

Article.index.import buffer unless buffer.empty?
puts count

puts "refresh index"

Article.index.refresh

我的文章，rb看起来像

article.rb

property :artikelnummer, type: 'string', index: 'not_analyzed'
property :eannummer, type: 'string', index: 'not_analyzed'

 property :bezeichnung, type: 'multi_field', fields: {
bezeichnung: {type: 'string'},
ngram: {:type => 'string', :index_analyzer => 'ngram_index_analyzer', :search_analyzer => 'ngram_search_analyzer'},
suggest: {:type => 'string', :analyzer => 'suggest_analyzer'}

}

  property :bezeichnung_zusatz, type: 'multi_field', fields: {
bezeichnung_zusatz: {type: 'string'},
ngram: {:type => 'string', :index_analyzer => 'ngram_index_analyzer', :search_analyzer => 'ngram_search_analyzer'}

}

  property :matchcode, type: 'string', index: 'not_analyzed'

  property :mengeneinheit, type: 'string', include_in_all: false

  property :gewicht, type: 'float', include_in_all: false

  property :hersteller, type: 'multi_field', fields: {
hersteller: {type: 'string'},
unchanged: {type: 'string', :index => 'not_analyzed'},
ngram: {:type => 'string', :index_analyzer => 'ngram_index_analyzer', :search_analyzer => 'ngram_search_analyzer'}

}

     property :hersteller_nummer, type: 'string', index: 'not_analyzed', include_in_all: false

  property :hersteller_artikelnummer, type: 'string', index: 'not_analyzed'

  property :gruppe, type: 'multi_field', fields: {
gruppe: {type: 'string'},
ngram: {:type => 'string', :index_analyzer => 'ngram_index_analyzer', :search_analyzer => 'ngram_search_analyzer'}
  }

这个结构我必须用来创建表
