routes.rb 文件：

get "dcrelations/create" 
get "dcrelations/destroy"
resources :dcrelations
match 'derelations/create' => 'dcrelations#create'
match 'derelations/destroy' => 'dcrelations#destroy'

表格文件：

<%= form_tag(:controller => "dcrelations", :action => "create", :method => "post") do %>
  <div class="field">
    <%= hidden_field_tag(:clinic_id, @clinic.clinic_id) %>
    <%= label_tag(:doctor_id, "doctor_id: ") %><br />
    <%= number_field_tag(:doctor_id) %>
  </div>
  <%= submit_tag("Add Doctor") %>
<% end %>

渲染表单文件：

<%= render 'shared/dcrelation_form' %>

控制器文件：

def create
  @dcrelation = Dcrelation.new(params[:clinic_id],params[:doctor_id])
  if @dcrelation.save
    flash[:success] = "doctor added!"
    redirect_to root_url
  else
    render 'clinic/show'
  end
  respond_to do |format|
    format.html # show.html.erb
    format.json { render json: @clinic }
  end
end

伙计们，我只想使用 form_tag 来更新数据库。我被这个错误困住了，已经搜索了几个小时。感谢您的所有帮助！！！！！！！

action => :create从您的 form_tag 声明中删除。

根据您的倾斜路线，您可以将 POST 解析为 dcrelations#create 的唯一路线是 URI/dcrelations(.:format)
