创建form_for用于贡献用户图像和描述 [英] Creating form_for for atributes User image and description

问题描述

我有一个设计的rails应用程序，我向用户添加了一个配置文件图像和一个描述。我想做的是创建一个页面（不同的默认注册/编辑），用户登录后，只能设置这两个属性（图像和描述）。

I have a rails application with devise, and I added to users a profile image, and a description. What I want to do is to create a page (DIFFERENT of the default registration/edit) where the users, after logged in, can set only this two atributes(image and description).

        <%= form_for(:user, html: { method: :put, :multipart => true })) do |f| %>
         <div class="form-group">
           <%= f.label :Profile_Image %>
           <%= f.file_field :image, class: "form-control" %>
         </div>
         <div class="form-group"> 
          <%= f.label :Descrição %>
            <%= f.text_area :description, class: "form-control", rows: "10" %>
         </div>
        <% end %>

我已经尝试过两个不同的控制器，没有一个工作：

I have already tried two different controllers and none of them worked:

def edit
end

def edit
  @user = User.find(params[:id])
end

我的配置 - >路由是：

My config -> routes are:

get "edit" => "pages#edit"
post "edit" => "pages#edit"

但是当我点击提交它什么都不做！我是新的在rails，我正在努力想出几个小时...如何创建页面只更新图像和描述？感谢

But when i click submit it does nothing! I am new at rails and I am trying to figure this out for hours... How can I create a page to update only the image and the description? Thanks

推荐答案

您需要在控制器中使用更新方法。您的编辑方法允许表单呈现，但您需要这样：

You need an update method in your controller. Your edit method allows the form to render, but you need something like this:

def update
   current_user.update(user_params)
end

那么你的控制器中会有另一个方法叫user_params，看起来像这样。我被教导把它放在一个私人标题下。

Then you would have another method in your controller called user_params, which would look something like this. I was taught to put it under a private heading.

private
   def user_params
     params.require(:user).permit(:profile_image, :description)
   end

我相信有一种使用你的更新方法来包含你的参数的快捷方式，但是这样做可以。

I believe there is a shortcut way of including your params with your update method, but this will do.
