How to link to create action using link_to tag in rails

Question

I tried to link to create action, and thought something like

    <%= link_to "Create new user", {controller: 'users' , action: 'create'}, method: 'post'  %>

, but when I click the generated link nothing happens and the url changes to

    http://0.0.0.0:3000/users?method=POST+%2Fusers

which indicates that the request is handled as a GET request and not a POST, any ideas ?

here is the create action from the users controller

        def create


        @user = User.new params[:user]

        if @user.save
            flash[:notice] = 'User has successfully been created.'
            redirect_to users_path
        else
            flash[:notice] = 'There was an error creating this user.'
            redirect_to :back
        end

end 

Answer 1

在rails中： <%= link_to 'Create new user' , new_user_path %> ，请查阅文档以获取有关路由的更多信息。

尝试使用（未经测试）：

<%= link_to "Create new user", {controller: 'users' , action: 'create', method: 'post'}  %>

Answer 3

You should use the named paths as they are generated from your routes.

<%= link_to "Create new user", users_path, method: "post" %>

You can find the names of these methods by running rake routes and looking at the first column. Append _path for local links and _url for full URLs.
