我正在尝试将文件导入 excel,但是当我尝试使用相关数据创建记录时,它向我显示以下错误:
no implicit conversion of Symbol into Integer
在这一行:
list.detallelp_attributes = {Articulo: row["Articulo"], Minimo: row["Minimo"], Maximo: row["Maximo"], IdEmpresa: empresa}
这是我的列表控制器和我用来导入的方法:
has_many :detallelp, class_name: "Deta", foreign_key: "ListaId"
accepts_nested_attributes_for :detallelp
def self.import(file,empresa)#importar
@errors = []
spreadsheet = open_spreadsheet(file)
header = spreadsheet.row(1)
(2..spreadsheet.last_row).each do |i|
row = Hash[[header, spreadsheet.row(i)].transpose]
list = find_by_id(row["id"]) || new
list.attributes = {id: row["id"], Lista: row["Nombre"], Tipo: row["Tipo"], FechaIni: row["Fecha inicial"], FechaFin: row["Fecha final"], IdEmpresa: empresa}
list.detallelp_attributes = {Articulo: row["Articulo"], Minimo: row["Minimo"], Maximo: row["Maximo"], IdEmpresa: empresa}
if list.save
# stuff to do on successful save
else
list.errors.full_messages.each do |message|
@errors << "Error fila #{i}, columna #{message}"
end
end
end
@errors # <- need to return the @errors array
end
我在列表控制器中的方法导入:
def import
empresa = current_usuario.empresa_id
@errors = List.import(params[:file], empresa)
if @errors.present?
render :errorimportation; #Redirije a dicha vista para mostrar los errores
return;
else
redirect_to listap_path, notice: "listas importadas."
end
end
这是我的“deta”控制器:
belongs_to :list, class_name:"List", foreign_key: "ListaId"
