表单输入不会创建记录

Question

我正在使用回形针和保管箱进行图像处理。

我不知道为什么我会这样做。我尝试解决sqlite3繁忙异常错误的一些解决方案并不起作用。

但我也怀疑我的参数在某种程度上是不正确的...... 控制器指定我需要一个角色对象，但参数似乎没有。我知道我使用了一个名为:image的文件附件，但是一旦图像上传并提交了表单，paperclip，imagemagick和dropbox就会处理图像属性的创建。

这是我在浏览器中收到的错误。

形式：     = form_for（@character，：html =＆gt; {：multipart =＆gt; true}）do | f |

- if @character.errors.any?
    #error_explanation
        %h2= "#{pluralize(@character.errors.count, "error")} prohibited this character from being saved:"
        %ul
            - @character.errors.full_messages.each do |msg|
                %li= msg

#stripe_error.alert.alert-danger{ :style => "display:none" }
    %noscript JavaScript is not enabled and is required for this form. First enable it in your web browser settings.

.form-group
    = f.label :name
    = f.text_field :name
.form-group
    = f.label :image
    = f.file_field :image   
.action
    = f.submit

控制器：

def create
@character = Character.new(character_params)

respond_to do |format|
  if @character.save
    format.html { redirect_to @character, notice: 'Character was successfully created.' }
    format.json { render action: 'show', status: :created, location: @character }
  else
    format.html { render action: 'new' }
    format.json { render json: @character.errors, status: :unprocessable_entity }
  end
end
end

...

private
# Use callbacks to share common setup or constraints between actions.
def set_character
  @character = Character.find(params[:id])
end

# Never trust parameters from the scary internet, only allow the white list through.
def character_params
  params.require(:character).permit(:name, :image)
end
end
