应用程序布局未应用于表单

Question

在app / controllers / fw_exports_controller.rb中，我有：

def import_spreadsheet
  @followeds = Followed.all.order(:screen_name)
  @import_spreadsheet = FwExport.new
  render partial: 'fw_exports/import_spreadsheet'
end

在app / views / layouts / application.html.slim中，我有：

doctype html
html
  head
    meta content=("text/html; charset=UTF-8") http-equiv="Content-Type" /
    meta content="width=device-width, initial-scale=1.0" name="viewport" /
    title= content_for?(:title) ? yield(:title) : t('project_name')
    meta content=("#{content_for?(:description) ? yield(:description) : t('project_name')}") name="description" /
    = stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true
    = javascript_include_tag 'application', 'data-turbolinks-track' => true
    = csrf_meta_tags
  body
    header
      = render 'layouts/navigation'
    main role="main"
      = render 'layouts/messages'
      = yield
      = render "layouts/footer"

在app / views / layouts / _navigation.html.slim中，我有：

nav.navbar.navbar-default role="navigation"
  .container
    .navbar-header
      a.navbar-brand href="#"
        = t('parnassus_tools_home')
    .navbar-left
      ul.nav.navbar-nav
        li
          a
          = link_to t('menus.upload_file'), import_spreadsheet_path

在app / views / fw_exports / _import_spreadsheet.html.slim中，我有：

.container
  h1
    = t('fw_exports.choose_file_to_upload')
  = form_tag process_imported_spreadsheet_path, html: { multipart: true }
    .form-group
      = file_field_tag :import_file
    - if !@followeds[0].nil?
      .form-group
        = select_tag "followed_id", options_from_collection_for_select(@followeds, "id", "screen_name", "1")
    .form_group
      .sr-only
        = label_tag t('fw_exports.screen_name_to_add')
      = text_field_tag :screen_name_addition, placeholder: t('fw_exports.screen_name_to_add')
    = button_tag(type: 'submit', class: "btn btn-primary") do
      i.icon-ok.icon-white
      = t('fw_exports.import')    

在app / views / landings / index.html.slim中，我有（这是主页）：

h1 Home Page
p test text

这是我在主页上看到的内容：

但是，当我点击主页上的“上传文件”菜单项时，我看到的是：

为什么应用程序布局不适用于表单？

Answer 1

您需要渲染为模板而不是部分渲染。首先，创建一个视图模板：

应用/视图/ fw_spreadsheet / import_spreadsheet.html.slim

= render 'fw_exports/import_spreadsheet_form'

接下来，通过将 app / views / fw_spreadsheet / _import_spreadsheet.html.slim 的名称更改为 app / views / fw_spreadsheet / _import_spreadsheet_form.html.slim 来重命名您的部分内容

最后，按如下方式修改您的控制器：

应用/控制器/ fw_exports_controller.rb

def import_spreadsheet
  @followeds = Followed.all.order(:screen_name)
  @import_spreadsheet = FwExport.new
  render 'fw_exports/import_spreadsheet'
end
