我正在为我的rails应用程序创建一个文档上传表单,一切正常,除了当我尝试显示刚刚上传的.txt文档时,文档被下载了

这是在我的show.html.erb文件上运行的两行代码

“查看文件”和“下载”按钮都在下载文件

如何显示文件

这是应用程序控制器:

class ApplicationController < ActionController::Base
    before_action :configure_permitted_parameters, if: :devise_controller?

    protected

    def configure_permitted_parameters
        added_attrs = [:username, :email, :password, :password_confirmation, :remember_me]
        devise_parameter_sanitizer.permit :sign_up, keys: added_attrs
        devise_parameter_sanitizer.permit :account_update, keys: added_attrs
    end
end
class ApplicationController
这是文件管理员。正在上载的文件称为文档:

class DocumentsController < ApplicationController
  before_action :set_document, only: [:show, :edit, :update, :destroy]
  # GET /documents
  # GET /documents.json
  def index
    @documents = Document.all
  end

  # GET /documents/1
  # GET /documents/1.json
  def show
  end

  # GET /documents/new
  def new
    @document = Document.new
  end

  # GET /documents/1/edit
  def edit
  end

  # POST /documents
  # POST /documents.json
  def create
    @document = Document.new(document_params)

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

  # PATCH/PUT /documents/1
  # PATCH/PUT /documents/1.json
  def update
    respond_to do |format|
      if @document.update(document_params)
        format.html { redirect_to @document, notice: 'Document was successfully updated.' }
        format.json { render :show, status: :ok, location: @document }
      else
        format.html { render :edit }
        format.json { render json: @document.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /documents/1
  # DELETE /documents/1.json
  def destroy
    @document.destroy
    respond_to do |format|
      format.html { redirect_to documents_url, notice: 'Document was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

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

    # Only allow a list of trusted parameters through.
    def document_params
      params.require(:document).permit(:title, :description, :file)
    end
end
类文档控制器
您应该检查是否在rails控制器中使用选项
disposition::inline
发送文件。该选项的默认值是
“附件”

例如,在控制器操作中,发送文件,例如:

send_file document.file,
          :type => "application/pdf",
          :file_name => document.file.name,
          :disposition => 'inline'

如果您想在单独的选项卡中打开链接,只需在链接选项中添加
目标:''u blank'

我已添加到原始问题中。如果你可以看一下控制器,因为我有点迷路了。你试过把
send\u文件添加到get方法吗?这应该能奏效。然后,您可以在中更改链接:
。这将由控制器的get方法处理,get方法将返回带有处置内联的文件。请尝试重新编辑您的帖子,以便更易于阅读
