我有2个div:users_list和messages。我编写了部分代码,从发送消息的数据库用户名中进行选择。但是我该怎么做呢:
我点击了用户名,在右侧div中,它从数据库消息列,文本中选择并在此处为每个用户显示。
下一步怎么办?您可以写下我将回答的答案。
<% @users_list.each do |user| %>
<li>
<%= user.message_for %>
</li>
<% end %>
我写了代码:
def show_message
Message.all_messages(session[:username]).from
end
function message_for(username){
$.ajax({
url: '/show_message',
method: 'POST',
data: {
to: username
},
success: function(response){
alert(response);
}
})
}
Message.rb模型def:
def self.all_messages(to)
@to = params[:to]
Message.where(to: to).order(date: :desc)
end
然后打印下一个错误:

更新 我的路线档案:
resources :users
resources :bookworms
resources :sessions
resources :covers
resources :messages
root 'bookworm#index'
get '/profile' => 'bookworm#profile'
get '/messages' => 'messages#index'
get '/login' => 'users#login'
post '/show_messages' => 'messages#show_message'
答案 0 :(得分:0)
在路线档案中定义路线
get '/show_message' => 'messages#show_message'
并遵循js代码
function message_for(username){
$.ajax({
url: '/show_message',
method: 'GET',
success: function(response){
alert(response);
}
})
}
