表单字段不保存到数据库 - Ruby on Rails的

Question

我这里有https://pastebin.com/JfXr054y

在routes.rb形式我有

resources :landslides, only: [:new, :create, :index] 

在landslides_controller.rb我

def new 
    @landslide = Landslide.new(landslide_params) 

    @landslide.save 
    render plain: @landslide.inspect 
    end 

和

def landslide_params 
    params.require(:landslide).permit(:total_id, :year_id, :start_date, :end_date, :day_number, :continent, :country, :location, :type, :admin_level, :new_lat, :new_long, :mapped, :spatial_area, :fatalities, :injuries, :notes, :sources) 
end 

为什么表格没有保存到表格中？

Answer 1

new是执行#save的错误方法。应该在create

def new 
    @landslide = Landslide.new 
    end 

    def create 
    @landslide = Landslide.new(landslide_params) 
    if @landslide.save 
     render plain: @landslide.inspect 
    else 
     render :new 
    end 
    end 

此外，您的窗体看起来不对。在返回PARAMS表单数据的位置取决于控制的name领域，而不是在id

而不是

%input#location.form-control{:type => "Location"} 

我希望看到

%input#landslide_location.form-control{:type => "text", :name => "landslide[location]"}
