xController#show 处理/更新为 HTML 而不是 JS

Question

我的数据库中有一个表，我正在页面中显示。

问题发生在我保存更改时。

我需要使用 js 的 Rails 进程，并且当您单击保存时不会将用户重定向到另一个页面。

到目前为止，我可以保存更改，但我总是被重定向到由 HTML 而不是 JS 处理的其他页面。

控制器：

filter_resource_access :nested_in => :releases
filter_resource_access :nested_in => :project

respond_to :js, only: [:update, :edit, :show]
respond_to :html

before_filter :load_issue, :load_project, :load_release

def edit
end

def update
  if @issue_value.update_attributes(params[:issue_value])
    flash.now[:notice] = t('messages.successfully_updated_entity.f',
                                             :entity => IssueValue.model_name.human)
    respond_to do |format|
      format.js
    end
  end
end

_issue_values_table：

<table class="zebra-striped">

 <thead>
 <tr>
   <th><%= IssueValue.human_attribute_name :name %></th>
   <th><%= IssueValue.human_attribute_name :value %></th>
   <th><%= IssueValue.human_attribute_name :client_value %></th>
   <th></th>
</tr>
</thead>
<tbody>
<% @issue_types = IssueType %>
<% for issue_value in @release.issue_values.order("issue_type_id") %>
  <%= content_tag_for :tr, issue_value, :class => "clickable" do %>
    <td width="42%"><%#= t(@issue_types.find(issue_value.issue_type_id).label_key) %></td>
    <td width="20%">
      <%= number_to_currency issue_value.value %>
    </td>
    <td width="20%">
      <%= number_to_currency issue_value.client_value %>
    </td>
    <td width="12%" class="icons right">
      <%= edit_icon issue_value, [:edit, @project, @release, issue_value], :remote => true, 'data-default-action' => true %>
    </td>
   <% end %>
<% end %>
</tbody>

_form_row：

 <td colspan="4">
   <%= form_for [@project, @release, @issue_value], :remote => true, :html => {:style => "margin:0"} do |f| %>
  <table class="basic">
    <tr>
      <td class="span8 middle">
        <div class="clearfix">
          <%#= f.text_field :name, :placeholder => IssueType.human_attribute_name(:name),
                           :autofocus => true, :class => "span10" %>
        </div>
      </td>
      <td class="span5 middle">
        <div class="clearfix">
          <%= f.text_field :value, :placeholder => IssueValue.human_attribute_name(:value),
                   :autofocus => true, :class => "span2" %>
        </div>
      </td>
      <td class="span5 middle">
        <div class="clearfix">
          <%= f.text_field :client_value, :placeholder => IssueValue.human_attribute_name(:client_value),
                   :class => "span2" %>
        </div>
      </td>
      <td class="span2 icons">
        <%= f.submit t('actions.save'), :disable_with => t('messages.please_wait'), :class => 'btn small', :remote => true %>
      </td>
    </tr>
  </table>
<% end %>

在 views/issue_values 我有：

1. edit.js.erb

2. show.js.erb

3. update.js.erb

4. _form_row.html.erb

5. _issue_values_table.html.erb

嗯，我不明白为什么这不起作用。

有人帮帮我吗？

Answer 1

如果您不需要重定向，则只需将其删除。和add respond_to/respond_with to controller。此外，您还需要 update.js.erb 来处理成功保存记录时的情况。像这样：

class IssueValuesController < LoginRequiredController
  respond_to :js, only: [:update]
  respond_to :html
  filter_resource_access :nested_in => :releases 

  def update
    if @issue_value.update_attributes(params[:issue_value])
      flash.now[:notice] = t('messages.successfully_updated_entity.f',
                                                 :entity => IssueValue.model_name.human)
    end
    respond_with(@issue_value)
  end

# rest of the class ommited
end

解决方法：

尝试将您的表单更改为：

<%= form_for [@project, @release, @issue_value], :remote => true, :html => {:format => "js", :style => "margin:0"} do |f| %>
