问题

使用 devise 登录后，我路由到名为“/opinions”的主页当我访问表单以创建一个新论坛并点击提交时，“ 表格 post 到 '/opinions' 正确" 但我在我的用户页面“/users/1”中呈现相同的表单当我点击提交时，我 git 这个错误。"

我做错了什么请帮助我？

好吧，错误已分派，因为您不应该对 /resource/:id (/users/2) 进行 POST。如果您希望更新信息，请使用 PUT。我认为您正在将 @opinions 传递给 form_with 助手，我猜这是用户的一系列意见。如果是这样，您应该创建一个变量@opinion = Opinion.new 以在用户视图中正确执行。但请使用 UserController.rb 文件编辑 post 以更好地帮助您。

正确的做法应该是这样的：

##UserController.rb
...
def show ## I will guess that you are using Opinion form in User Show
  @user = User.find(:id)
  @opinions = @user.opinions
  @new_opinion = Opinion.new
end
...
## app/views/users/show.html.erb
...
<%= form_with(model: @new_opinion, local: false) do |form| %>
  <%= render 'opinions/form' form: form %>
<% end %>
...

## app/views/opinions/_form.html.erb
...
<div class="field rich p-3">
  <div class="control">
    <%= form.rich_text_area(
      :body, 
      label: "What's Your Opinion", 
      input_html: {class: "textarea"}, 
      wrapper: false, 
      label_html: {class: "label"}, 
      placeholders: "Your opinion...", 
      autofocuse: true 
    ) %>
  </div>
  ...
</div>
...
  <%= form.button :submit, class: "button is-info" %>
...

请记住，部分表单不应包含 form_with 标记。使用render标签的局部变量传递form属性

希望能帮到你。祝你好运！
