我试图隐藏搜索结果直到搜索发生之后。当我从主页单击搜索页面时，页面显示搜索框，但也显示表格中的所有数据库。我想只显示搜索选项和搜索按钮，然后根据搜索，显示正确的表格。
这是我的搜索视图：
<h1>Search</h1>
<%= form_tag search_path, method: :get do %>
Client :
<%= select(@projects, :client, Project.all.map {|p| [p.client]}.uniq, :prompt => "-Any-", :selected => params[:client]) %></br>
Industry :
<%= select(@projects, :industry, Project.all.map {|p| [p.industry]}.uniq, :prompt => "-Any-", :selected => params[:industry]) %></br>
Role :
<%= select(@projects, :role, Project.all.map {|p| [p.role]}.uniq, :prompt => "-Any-", :selected => params[:role]) %></br>

<%= select(@projects, :tech, Project.all.map {|p| [p.tech]}.uniq, :prompt => "-Any-", :selected => params[:tech]) %></br>
Business Division :
<%= select(@projects, :business_div, Project.all.map {|p| [p.business_div]}.uniq, :prompt => "-Any-", :selected => params[:business_div]) %></br>
Project Owner :
<%= select(@projects, :project_owner, Project.all.map {|p| [p.project_owner]}.uniq, :prompt => "-Any-", :selected => params[:project_owner]) %></br>
Exception PM
<%= select(@projects, :exception_pm, Project.all.map {|p| [p.exception_pm]}.uniq, :prompt => "-Any-", :selected => params[:exception_pm]) %></br>
Start Date :
<%= text_field_tag("start_date") %></br>
End Date :
<%= text_field_tag("end_date") %></br>
Status :
<%= select(@projects, :status, Project.all.map {|p| [p.status]}.uniq, :prompt => "-Any-", :selected => params[:status]) %></br>
Keywords :
<%= text_field_tag :keywords, params[:keywords] %></br>
<%= submit_tag "Search", name: nil %>
<% end %>
<% if @search %>

<% end %>
<% if @search %>

Results per page: <%= select_tag :per_page, options_for_select([10,20,50], params[:per_page].to_i), :onchange => "if(this.value){window.location='?per_page='+this.value;}" %>

以下是搜索操作：
def search
@search = params[:client], params[:industry], params[:role], params[:tech], params[:business_div], params[:project_owner], params[:exception_pm], params[:status], params[:start_date], params[:end_date], params[:keywords]
@project_search = Project.search(@search)
@project = Project.new(params[:project])
respond_to do |format|
format.html # search.html.erb
format.json { render :json => @project }
end
end
这是我的模特。
class Project < ActiveRecord::Base
attr_accessible :business_div, :client, :customer_benifits, :edited_date, :end_date, :entry_date, :exception_pm, :financials, :industry, :keywords, :lessons_learned, :project_name, :project_owner, :role, :start_date, :status, :summary, :tech

def self.search(search_client, search_industry, search_role, search_tech, search_business_div, search_project_owner, search_exception_pm, search_status, search_start_date, search_end_date, search_keywords)
return scoped unless search_client.present? || search_industry.present? || search_role.present? || search_tech.present? || search_business_div.present? || search_project_owner.present? || search_exception_pm.present? || search_status.present? || search_start_date.present? || search_end_date.present? || search_keywords.present?
if search_start_date != ""
search_start_date = Date.parse(search_start_date).strftime("%Y-%m-%d")
end
if search_end_date != ""
search_end_date = Date.parse(search_end_date).strftime("%Y-%m-%d")
end
where(['client LIKE ? AND industry LIKE ? AND role LIKE ? AND tech LIKE ? AND business_div LIKE ? AND project_owner LIKE ? AND exception_pm LIKE ? AND status LIKE ? AND start_date LIKE ? AND end_date LIKE ? AND keywords LIKE ?', "%#{search_client}%", "%#{search_industry}%" , "%#{search_role}%" , "%#{search_tech}%" , "%#{search_business_div}%" , "%#{search_project_owner}%" , "%#{search_exception_pm}%" , "%#{search_status}%", "%#{search_start_date}%", "%#{search_end_date}%","%#{search_keywords}%"])
end
def self.paginated_for_index(projects_per_page, current_page)
paginate(:per_page => projects_per_page, :page => current_page)
end
end
希望你能看到我试图做的事情。我收到错误wrong number of arguments (1 for 11)因为我没有拆分参数。但是当我使用*@search时，我会遇到很多错误。
在我试图隐藏表格之前，我在控制器中的原始代码看起来像这样：
@project_search = Project.search(params[:client], params[:industry], params[:role], params[:tech], params[:business_div], params[:project_owner], params[:exception_pm], params[:status], params[:start_date], params[:end_date], params[:keywords]).order(sort_column + ' ' + sort_direction).paginated_for_index(per_page, page）

你需要在将@search params传递给.search时将其展开，以告诉Ruby扩展你的参数数组，将单独的参数传递给Project.search
@project_search = Project.search(*@search)
修改 （回答您的后续问题）
使用
进行测试<% if @search %>
是不够的，因为它总是会有一个评估为true的值，即使它只是[]或["", "", "", "", "", "", "", "", "", "", ""]。正确检查此方法的一种方法是，如果搜索过滤器中的所有字段都为空，则创建一个新的布尔实例变量true。
# put this after you set @search in your action
@search_performed = !@search.reject! { |c| c.blank? }.empty?
现在使用
在视图中测试@search_performed
<% if @search_performed %>
答案 1 :(得分：0)
您要将数组存储在@search中，并且必须使用*运算符
@project_search = Project.search(*@search)
