我正在為我的 Rails 應用程序創建文檔上傳表單,一切正常,除了當我嘗試顯示剛剛上傳的 .txt 文檔時,該文檔被下載了嗎?
這些是在我的 show.html.erb 文件中運行的兩行代碼
<%= link_to '查看文件', @document.file %>
<%= link_to '下載', @document.file, 下載: '' %>
查看文件和下載按鈕都在下載文件。
我如何 go 關於顯示文件?
這是應用程序 controller:
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
這是文件 controller。上傳的文件稱為文件:
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
您應該檢查您發送的文件是否帶有選項disposition: :inline
in your rails controller。該選項的默認值為'attachment'
。
例如,在您的 controller 操作中發送您的文件,例如:
send_file document.file,
:type => "application/pdf",
:file_name => document.file.name,
:disposition => 'inline'
如果您希望您的鏈接在單獨的選項卡中打開,您只需將target: '_blank'
添加到您的鏈接選項。
