Question

我可以从＆＃34; new＆＃34;中获取视图中的对象。方法但无法从控制器的另一个方法获取它。为什么呢？

所以，我在routes.rb中有这个：

Rails.application.routes.draw do
    get 'horarios/new'=> 'horarios#new'
    get 'horarios/newprofessor'=> 'horarios#newprofessor'
end

这在horarios_controller.rb中：

class HorariosController < ApplicationController
    def new
        @horario = Horario.new
        @teste = "it prints!"
    end

    def newprofessor
        @teste = "it prints!"
    end
 end

并将其放在两个视图中（new.html.erb和newprofessor.html.erb）：

<% raise @teste.inspect %>

＆＃34; new＆＃34; view给了我这个对象，但是＆＃34; newprofessor＆＃34;观点说它没有。这是为什么？谢谢！

- 编辑（添加所有代码） horarios_controller.rb

class HorariosController < ApplicationController
    def new
        @horario = Horario.new
        @teste = "it prints!"
    end

    def addhorarioprofessor
        puts params[:Sex10]
        if params[:Sex10] == "1"
            puts "foi"
            @horario = Horario.where(:hora_inicio => "10:00", :dia_semana => "Sexta-feira").first
            @horario.update_attributes(:professor_id => 6)
            @horario.save
        end
        redirect_to '/'
    end 

    def create
        @horario = Horario.new(horario_params)
        if @horario.save
            redirect_to '/'
        else
            render 'new'    
        end
    end

    private
    def horario_params
        params.require(:horario).permit(:dia_semana, :hora_inicio, :hora_fim, :professor_id)
    end

    def index
        @horarios = Horario.all
    end

    def newprofessor
        @horarios_preenchidos = Hash.new
        @horarios = Horario.new
        @teste = "it prints!"
        for horario in @horarios
            if horario.professor_id != nil
                @tah_preenchido = true
            else
                @tah_preenchido = false
            end
            @horarios_preenchidos[horario.dia_semana+"_"+horario.hora_inicio] = @tah_preenchido
        end 
    end    
end

的routes.rb

Rails.application.routes.draw do
    get 'professors' => 'professors#index'
    get 'professors/new' => 'professors#new'
    get 'horarios/new'=> 'horarios#new'
    get 'horarios/newprofessor'=> 'horarios#newprofessor'
    post 'professors' => 'professors#create'    
    post 'horarios'=> 'horarios#create'
    post 'horarios/newprofessor' => 'horarios#addhorarioprofessor'
end

new.html.erb

<h1>Horarios#new</h1>
<p>Find me in app/views/horarios/new.html.erb</p>
<% raise @teste.inspect %>
<%= form_for(@horario) do |f| %>  
  <div class="field"> 
      <%= f.label :dia_semana %><br> 
      <%= f.text_area :dia_semana %><br>
    <%= f.label :hora_inicio %>

    <%= f.text_area :hora_fim %>

  </div> 
  <div class="actions"> 
    <%= f.submit "Create" %> 
  </div> 
<% end %>

newprofessor.html.erb：

<%= debug(params) if Rails.env.development? %>
<% raise @teste.inspect %>

当我把＃34; newprofessor＆＃34;作为控制器中的第一个方法工作的方法（我不知道为什么它工作）。

class HorariosController < ApplicationController
    def newprofessor
        @horarios_preenchidos = Hash.new
        @horarios = Horario.all
        @teste = "it prints!"
        for horario in @horarios
            if horario.professor_id != nil
                @tah_preenchido = true
            else
                @tah_preenchido = false
            end
            @horarios_preenchidos[horario.dia_semana+"_"+horario.hora_inicio] = @tah_preenchido
        end
    end   

    def new
        @horario = Horario.new
        @teste = "it prints!"
    end

    def addhorarioprofessor
        puts params[:Sex10]
        if params[:Sex10] == "1"
            puts "foi"
            @horario = Horario.where(:hora_inicio => "10:00", :dia_semana => "Sexta-feira").first
            @horario.update_attributes(:professor_id => 6)
            @horario.save
        end
        redirect_to '/'
    end 

    def create
        @horario = Horario.new(horario_params)
        if @horario.save
            redirect_to '/'
        else
            render 'new'    
        end
    end

    private
    def horario_params
        params.require(:horario).permit(:dia_semana, :hora_inicio, :hora_fim, :professor_id)
    end

    def index
        @horarios = Horario.all
    end


end

Rails - 控制器未传递给视图的变量
