[英]Gem Ransack doesn't return any results when searched with full name
I'm using Ransack with Rails 3. 我正在使用Ransack和Rails 3。
My views: 我的观点:
<%= search_form_for @search do |f| %>
<%= f.text_field :first_name_or_last_name_or_company_cont, :style => 'width:150px;padding-top:6px;' %><p class="button">
<%= f.submit "Search by name or company" %></p>
<% end %>
My schema: 我的架构:
create_table "users", :force => true do |t|
t.string "first_name",
t.string "last_name"
on the User model I have: 在用户模型上我有:
def full_name
"#{self.first_name} #{self.last_name}"
end
Working on the console. 在控制台上工作。
If I have user with first_name = "Foo"
, last_name = "Bar"
, when I search with either one, I get the results as expected. 如果我有
first_name = "Foo"
, last_name = "Bar"
,当我用任何一个搜索时,我得到了预期的结果。
When I search with full_name = "Foo Bar"
, I get no results. 当我使用
full_name = "Foo Bar"
搜索时,我没有得到任何结果。
I tried changing my text_field for Ransack to: 我尝试将我的text_field更改为Ransack:
<%= f.text_field :first_name_or_last_name_or_company_or_full_name_cont
I get first_name_or_last_name_or_company_or_full_name_cont is undefined
我得到
first_name_or_last_name_or_company_or_full_name_cont is undefined
is there a quick way to solve this without adding another column for full_name on my users table? 有没有一种快速解决方法,而无需在我的用户表上添加另一列full_name?
also : 还:
7: def index
8: search_params = params[:q]
=> 9: binding.pry
[1] pry(#<UsersController>)> search_params
=> {"first_name_or_last_name_or_company_cont"=>"Foo Bar"}
I guess I can split key value here to search the first name only. 我想我可以在这里分割键值来搜索名字。
You have to use a Ransacker
. 你必须使用
Ransacker
。 Add this in your User
model: 在您的
User
模型中添加:
ransacker :full_name do |parent|
Arel::Nodes::InfixOperation.new('||',
parent.table[:first_name], parent.table[:last_name])
end
You can check the Ransack GitHub wiki to more examples. 您可以查看Ransack GitHub wiki以获取更多示例。
Add the following code to your model: 将以下代码添加到模型中:
ransacker :full_name do |parent|
Arel::Nodes::InfixOperation.new('||',
Arel::Nodes::InfixOperation.new('||',
parent.table[:first_name], Arel::Nodes.build_quoted(' ')
),
parent.table[:last_name]
)
end
... and the following in your view: ......以及您认为的以下内容:
<%= f.label :full_name %><br>
<%= f.search_field :full_name_cont %>
The ransacker part was taken from the Ransack wiki . ransacker部分取自Ransack维基 。
