Before(:all) do 
    puts "HELLO ALL :D"
end

我的代码有问题:

/spec/factories.rb

require 'faker'
FactoryGirl.define do
    factory :booking_error do 
    booking_id       { Faker::Number.number(3).to_i }
    error_type_cd    BookingError.error_types.values.shuffle.first
    process_name     Enums::FlightEnum::PROCESSES.keys.shuffle.first
    description      "DESCRIPTION"
    old_value        "OLD_STRING"
    new_value        "NEW_STRING"
    end
end

/spec/models/booking_error_spec.rb

require 'spec_helper'
describe BookingError do
    before(:all) do
        @booking_error       = FactoryGirl.build(:booking_error)
        @booking_error_types = BookingError.error_types
    end

    it 'Validating BookingError save.' do
        @booking_error.save.should be_true
    end
end

我有一个数据框 df ，我想将一些列转换为类别类型。使用 pandas 我可以这样做：

    for col in categorical_collist:
        df[col] = df[col].astype('category')

我想在 pyspark 中进行列转换。我该怎么做？

我尝试在 pyspark 中使用以下代码。但它在操作过程中没有给出我的预期输出。

from pyspark.sql.types import StringType
for col in categorical_collist:
    df = df.withColumn(col, df[col].cast(StringType()))

当我跑步时:

:$ vagrant provision

要么

:$ vagrant up

我有一个错误:

我能够处理令牌,如果它作为查询字符串在URL中出现,或者如果它出现在标题中Authentication,并且令牌前缀为令牌Bearer,我只希望能够在标题中接收它.
