Rails：搜索表單在boostrap導航欄

我想添加搜索表單到bootstrap導航欄沒有運氣。搜索表單在app/views/searches/new.html.erb中正常工作。當我在app/views/layouts/_header.html.erb中添加相同的搜索表單時，我得到'表單中的第一個參數始終不能包含零或爲空。我試圖將表單中的@搜索更改爲搜索路徑，但沒有一個能夠正常工作。我會很感激任何提示如何使代碼更好，我覺得我可以用更優雅的方式在搜索模型中編寫代碼。謝謝你的幫助。Rails：搜索表單在boostrap導航欄

應用程序/視圖/佈局/ _header.html.erb

<%= form_for @search, html: {class: "navbar-form navbar-left"} do |f| %> 
<div class="input-group searchbar"> 
<%= f.text_field :keywords, class: "form-control", placeholder: "Search" %> 
    <span class="input-group-addon"> 
    <%= button_tag(:class => "white") do %> 
    <i class="glyphicon glyphicon-search"></i> 
    <% end %> 
    </span> 
    </div> 
<% end %>

搜索模型

def questions 
@questions = find_questions 
end 

def answers 
@answers = find_answers 
end 

def users 
@users = find_users 
end 

private 

def find_questions 
questions = Question.order(created_at: :desc) 
questions = questions.where("title like ? OR content like?", "%#{keywords}%", "%#{keywords}%") if keywords.present? 
questions 
end 

def find_answers 
answers = Answer.order(created_at: :desc) 
answers = answers.where("content like ?", "%#{keywords}%") if keywords.present? 
answers 
end 

def find_users 
users = User.order(:username) 
users = users.where("username like ?", "%#{keywords}%") if keywords.present? 
users 
end

搜索控制器

def new 
@search = Search.new 
end 

def create 
@search = Search.create!(allowed_params) 
redirect_to @search 
end 

def show 
@search = Search.find(params[:id]) 
end 

private 

def allowed_params 
params.require(:search).permit! 
end

問題控制器 - 我有答案相同的代碼和用戶控制器

條

def index 
@questions = Question.all 
if params[:search] 
    @questions = Question.search(params[:search]) 
end 
end

路線

searches GET  /searches(.:format)      searches#index 
     POST  /searches(.:format)      searches#create 
new_search GET /searches/new(.:format)     searches#new 
edit_search GET /searches/:id/edit(.:format)    searches#edit

當你得到那個錯誤後，點擊或之前？ – 7urkm3n

@ 7urkm3n我在嘗試打開我的網站時得到它，我的意思是當我打開本地主機時看到的第一件事是該錯誤 –

我沒有測試過，但它應該工作。不要忘記將search_path更改爲您自己的。

<%= form_tag ###search_path, method: :get do %> 
    <%= text_field_tag 'keywords', nil, placeholder: "Search", class: "form-control" %> 
    <%= submit_tag 'Search', name: nil %> 
<% end %>
