我先看一下我的铁路。

When I try to create a new client in my clients table im getting this error => undefined method model_name for NilClass:Class

我要告诉我,错误在我看来是第2行。

1: <%- model_class = @client.class -%>
2: <h1><%=t  .title , :default => model_class.model_name.human %></h1>
3: 
4: <p>
5:   <strong><%= model_class.human_attribute_name(:name) %>:</strong><br>

我在这里表达了我的看法。

<%- model_class = @client.class -%>
<h1><%=t  .title , :default => model_class.model_name.human %></h1>

<p>
  <strong><%= model_class.human_attribute_name(:name) %>:</strong><br>
  <%= @client.name %>
</p>
<p>
  <strong><%= model_class.human_attribute_name(:detail) %>:</strong><br>
  <%= @client.detail %>
</p>
<p>
  <strong><%= model_class.human_attribute_name(:more_detail) %>:</strong><br>
  <%= @client.more_detail %>
</p>
<p>
  <strong><%= model_class.human_attribute_name(:more_details) %>:</strong><br>
  <%= @client.more_details %>
</p>

<div class="form-actions">
  <%= link_to t( .back , :default => t("helpers.links.back")),
              clients_path, :class =>  btn   %>
  <%= link_to t( .edit , :default => t("helpers.links.edit")),
              edit_client_path(@client), :class =>  btn  %>
  <%= link_to t( .destroy , :default => t("helpers.links.destroy")),
              client_path(@client),
              :method =>  delete ,
              :confirm => t( .confirm , :default => t("helpers.links.confirm", :default =>  Are you sure? )),
              :class =>  btn btn-danger  %>
</div>

这里是我的控制师 =>

  respond_to :html

  def index
    @clients = Client.all
    respond_with (@clients)
  end

  def new
    @clients = Client.new
    respond_with (@clients)
  end

  def create
    @clients = Client.new(params[:name])
    if @clients.save
      flash[:notice] = "Client successfully created"
    end
    respond_with(@clients)
  end

  def destroy
  @clients = Client.find(params[:id])
  @clients.destroy
  flash[:notice] = "Client has been removed."
  respond_with(@clients)
  end

end

我看不出问题在哪里?

不久前,我安装了铁丝网,但并不认为这将产生很大影响。
