嗨,我在我的控制器行動給出這樣的:比賽中的regex控制器條件rails4
def create
@department = Department.create(department_params)
if @department.attachment.attach_content_type == 'image\/.*'
render :action => :new
else
redirect_to departments_path, notice: I18n.t('department_created')
end
end
和我得到這個在我的PARAMS
Parameters: {"utf8"=>"✓", "authenticity_token"=>"Y2GmRyk6SEh12vJQMEWpdphojFeCXWxhECLaJ1bBww6sZ7P9CmjLEmxK/vGPx2tZ+15zy0W4+tYf26zpHSL9Yw==", "department"=>{"name"=>"Quality Assurancebnnnnnnnnnnnn", "attachment_attributes"=>{"attach"=>#<ActionDispatch::Http::UploadedFile:0xb41fac20 @tempfile=#<Tempfile:/tmp/RackMultipart20150608-4331-a3x9h7.jpeg>, @original_filename="index.jpeg", @content_type="image/jpeg", @headers="Content-Disposition: form-data; name=\"department[attachment_attributes][attach]\"; filename=\"index.jpeg\"\r\nContent-Type: image/jpeg\r\n">}}, "button"=>""}
它不是我的,如果條件裏想它去在我的其他部分,但content_type是圖像/ JPEG,我想如果我的content_type從圖像開始,那麼它不會保存。我曾嘗試這也
p "*********************************8"
p (@department.attachment.attach_content_type).to_s
@content_type = (@department.attachment.attach_content_type).to_s
p 'rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr'
p @content_type == "image\/.*"
,但它給了我這個輸出控制檯:
"*********************************8"
"image/jpeg"
"rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr"
false
請指導如何解決這個問題。
沒有它不工作 – Aniee
是'@ department.attachment.attach_content_type'實際上是一個字符串?看到更新,強制它與'to_s' – arco444
是的,它是字符串 – Aniee
