如何在数据库中发送数据并在rails3上的ruby中使用json格式显示所需部分?
我的表格就像这样
<%= form_for(@user) do |f| %>
<% if @user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@user.errors.count, "error") %> prohibited this user from being saved:</h2>
<ul>
<% @user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :email %><br />
<%= f.text_field :email %>
</div>
<div class="field">
<%= f.label :login %><br />
<%= f.text_field :login %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>

在控制器中:
def show
@user = User.find(params[:user_id]
respond_to do |format|
format.json { :render => @user }
end
end
您可以通过覆盖用户模型中的as_json
来自定义JSON输出:
def as_json(options=false)
self.include_root_in_json = false
options = (options || {}).reverse_merge(
:except => [:updated_at, :created_at, :id],
:include => :some_association
)
super(options)
end
