Ruby on Rails: Show results on page, after search - ruby-on-rails

Question

I am trying to hide my search results until after the search has happened. At the moment when I click from the home page to the search page, the page shows the search boxes, but also shows all of the database in a table. I am wanting to just show the search options, and search button, then depending on the search, show the right table.
Here is my search view:
<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>
Technologies :
<%= 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 %>
<h3><%=#project_search.total_entries%> results</h3>
<% end %>
<% if #search %>
<table class = "pretty">
<table border="1">
<tr>
<th><%= sortable "project_name", "Project name" %> </th>
<th><%= sortable "client", "Client" %></th>
<th>Exception pm</th>
<th>Project owner</th>
<th>Tech</th>
<th>Role</th>
<th>Industry</th>
<th>Financials</th>
<th>Business div</th>

<% if false %>

<% end %>
</tr>
<%# end %>
<% #project_search.each do |t| %>
<tr>
<td><%= t.project_name %></td>
<td><%= t.client %></td>
<td><%= t.exception_pm %></td>

<% end %>
<!td><%#= link_to 'Show', project %></td>
<!td><%#= link_to 'Edit', edit_project_path(project) %></td>
<!td><%#= link_to 'Destroy', project, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</table>
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;}" %>
<br />
<%= hidden_field_tag :direction, params[:direction] %>
<%= hidden_field_tag :sort, params[:sort] %>
<%= hidden_field_tag :per_page, params[:per_page] %>
<%= hidden_field_tag :page, params[:page] %>
<%= will_paginate (#project_search) %>
<%= button_to "Search Again?", search_path, :method => "get" %>
<%# end %>
<%= button_to "Home", projects_path, :method => "get" %>
Here is the search action:
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
and here is my model.
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
validates_presence_of :business_div, :client, :customer_benifits, :end_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
Hopefully you can see what I have tried to do. I am getting the error wrong number of arguments (1 for 11) as I haven't split the params. But when I use *#search I get loads of errors.
My original code in the controller looked like this before I went about trying to hide the table:
#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)

Answer 1

You need to splat the #search params when passing it to .search to tell Ruby to expand your array of arguments to separate arguments to be passed to Project.search
#project_search = Project.search(*#search)
Information on using splat
Edit (to answer your follow-up question)
Testing with
<% if #search %>
isn't enough because it will always have a value that evaluates to true, even if its just [] or ["", "", "", "", "", "", "", "", "", "", ""]. One way to check this properly would be to create a new boolean instance variable that is true if all fields are blank in the search filters.
# put this after you set #search in your action
#search_performed = !#search.reject! { |c| c.blank? }.empty?
and now test #search_performed in your view with
<% if #search_performed %>

Answer 2

you are storing array in #search and u have to use * operator
#project_search = Project.search(*#search)
