沒有路線匹配，form_tag，在鐵路上的紅寶石

Question

route.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 %>

渲染表單文件：

<%= 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

伙計們，我只想使用form_tag來更新數據庫。 我被這個錯誤困住了，已經搜索了幾個小時。 感謝您的所有幫助！！！！

Answer 1

從form_tag聲明中刪除action => :create 。

根據您的傾斜路線，POST解析為dcrelations＃create的唯一路線是URI /dcrelations(.:format)
