ActionController::MethodNotAllowed（仅允许 get 和 post 请求。）：

不知道发生了什么事。我使用了以下代码来尝试编辑类别的名称，但收到上面的错误消息。我的表单和提交编辑代码是： -

<% form_for :category, :url => categories_url(@category),:html => { :method => :put } do |f| -%>
<p>Name: <br /><%= f.text_field :name, :size => 60 %></p>
<%= submit_tag 'Save' %> or <%= link_to 'cancel', admin_categories_url%>

非常简单的东西。我的控制器代码是：- 默认编辑 @category = Category.find(params[:id]) 结束

# PUT /类别/1 # PUT /categories/1.xml 默认更新 @category = Category.find(params[:id]) @category.update_attributes(params[:category])

respond_to do |wants|
  wants.html { redirect_to admin_categories_url }
  wants.xml  { render :xml => @category.to_xm }
end

end

这段代码适用于其他事情 - 例如博客文章，所以我不确定我哪里出错了。帮助？？

Not sure what's going on. I've used the following bit of code to try and edit the name of a category, but I'm getting the error message above. My code for the form and submit for the edit is: -

<% form_for :category, :url => categories_url(@category),:html => { :method => :put } do |f| -%>
<p>Name: <br /><%= f.text_field :name, :size => 60 %></p>
<%= submit_tag 'Save' %> or <%= link_to 'cancel', admin_categories_url%>

So pretty straight forward stuff. My controller code is: -
def edit
@category = Category.find(params[:id])
end

# PUT /categories/1
# PUT /categories/1.xml
def update
@category = Category.find(params[:id])
@category.update_attributes(params[:category])

respond_to do |wants|
  wants.html { redirect_to admin_categories_url }
  wants.xml  { render :xml => @category.to_xm }
end

end

This code has worked for other things - such as blog articles, so I'm not sure where I{"m going wrong. Help??

我想你想要 :url => Category_url(@category)（非复数）。

这往往会更干净一些...让路由系统找出如何最好地保存@category。

/app/controllers/admin_categories_controller.rb（猜测）

def new
  @category = Category.new
end

/app/views/admin_categories/new.html.erb

<% form_for @category do |f| %>
<p>
<%= f.label :name%>: <%= f.text_field :name, :size=>60%>
</p>
<%= f.submit :save%> or <%= link_to 'cancel', admin_categories_url%>

This tends to be a bit cleaner... Let the Routing system figure out how best to save the @category.

/app/controllers/admin_categories_controller.rb (guessed at this)

def new
  @category = Category.new
end

/app/views/admin_categories/new.html.erb

<% form_for @category do |f| %>
<p>
<%= f.label :name%>: <%= f.text_field :name, :size=>60%>
</p>
<%= f.submit :save%> or <%= link_to 'cancel', admin_categories_url%>
