标签: remotipart

看起来Remotipart实际上并没有被用来提交我的表单,因此当我查看提交表单的params时,图像完全被遗漏了.

remotipart_submitted? 返回false

PARAMS: {"utf8"=>"?", "product"=>{"name"=>"RemotipartFails", "price"=>"10", "description"=>"Please work"}, "action"=>"create", "controller"=>"products"}

下面是更相关的代码

宝石

gem "jquery-rails"
gem "remotipart", "~> 1.2"

使用Javascript

//= require jquery
//= require jquery_ujs
//= require jquery.remotipart

形成

<%= form_for(:product, url: products_path, remote: true, html: { multipart: true, class: "form-horizontal" }) do |f| %>
  <div class="margin-top-10 margin-bottom-10">
    <div class="input-left">
      <%= f.text_field :name, { placeholder: "Name", class: "form-control" } %>
    </div>
    <div class="input-right">
      <%= f.number_field :price, { placeholder: "Price", class: "form-control" } %>
    </div>
    <div class="clearfix margin-bottom-10"></div>
    <div class="input-full"> …

当尝试通过Carrierwave和Rails 5远程上传图像时,我遇到了编码错误:

编码:: UndefinedConversionError - 从ASCII-8BIT到UTF-8的"\ x89"

我已经看过这个答案以及答案提出的activesupport-json_encoder gem,但没有运气.宝石似乎不支持导轨5.

我的表单是一个正常的多部分rails表单,如下所示:

= bootstrap_form_for @image, url: members_profile_path(current_user), remote: true, html: {  multipart: true } do |f|  
  = f.file_field :attachment
  = f.button "Save"

包含图像的字段称为"附件".在我的控制器中,我的代码如下所示:

def create_profile_image
  respond_to do |format|
    @image.entity_id = current_user.id
    if @image.validate(params[ :image ])
      @image.save
      format.json { render json: @image, status: :ok }
    else
      format.json { render json: @image.errors, status: :unprocessable_entity }
    end
  end
end

我正在使用改革宝石处理允许的参数.我确保允许附件参数.此外,我还添加了Remotipart gem,以通过Rails简化远程文件上传.

任何想法,为什么我可能会出现此错误？

UPDATE

这是我在日志中可以看到的:

Started …

Rails 5 和载波

我加：

gem 'remotipart', '~> 1.3.1'

和

//= require jquery.remotipart

我有这样的表格：

= simple_form_for state, remote: true do |f|
  = f.input :wsr

该表单的输出：

<form class="simple_form" novalidate="novalidate" id="edit_odc_state_73" enctype="multipart/form-data" action="/odc_states/73" accept-charset="UTF-8" data-remote="true" method="post">

但是当我提交表单时：

ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken):

为什么以 HTML 格式发送，有什么想法吗？

我正在使用Remotipart上传文件.Rails-Controller处理文件,但我无法弄清楚如何获得以下ajax响应.这是我的js代码.

$file.children(".description").html(
    '<%= form_for FileObject.new, :url => file_object_index_path , :html => { :multipart => true }, :remote => true do |f| %>' +
    '<div class="field">' +
    '<%= f.label :file %>' +
    '<%= f.file_field :file %>'+
    '</div>' +
    '<input type="hidden" name="directory_object_id" value="' + current_directory.id +'" />' +
    '<div class="actions">' +
            '<%= f.submit %>' +
            '</div>' +
    '<% end %>'
 );
$("form").bind('ajax:success', function(){
   alert("success");
});

也许有人之前已经解决过这个
