使用的form_tag我的实例变量不保存,当我试图寻找一个API [英] Using form_tag my instance variables are not saving when I try to search an API
问题描述
我试图创建一个简单的Rails应用程序,将检索API数据。我的初衷不是保存搜索到数据库中,这就是为什么我用的form_tag。当我在控制台中运行我的搜索工作,但是当我打电话 @Results
或 @first_match
,它给了我零。提前很多感谢。
演员控制器方法
高清指数
@Results = API :: Topic.search([:演员])
@first_match = @ results.values.first
结束
演员表
=的form_tag'演员/秀,方法:做得到
= text_field_tag演员
= submit_tag让我看看
路线
RailsApp :: Application.routes.draw做
资源:演员
结束
更新
由于我在表单中显示的方法路由。我能在我的节目在控制器方法来检索的变量。我不知道这是不是最好的办法,但。
高清节目
@Results = API :: Topic.search([:演员])
@first_match = @ results.values.first
结束
我想,你需要使用 API :: Topic.search(PARAMS [:演员])
I'm trying to create a simple Rails app that will retrieve API data. My original intention were not to save the search to the database, which is why I used form_tag. My search works when I run in the console, but when I call @results
or @first_match
, it give me nil. Many thanks in advance.
Actor Controller Method
def index
@results = API::Topic.search([:actor])
@first_match = @results.values.first
end
Actor Form
= form_tag 'actors/show', method: :get do
= text_field_tag "Actor"
= submit_tag "Show me"
Routes
RailsApp::Application.routes.draw do
resources :actors
end
Update
Since I am routing in the show method in the form. I was able to retrieve the variables in my show method in the controller. I don't know if this is the best way though.
def show
@results = API::Topic.search([:actor])
@first_match = @results.values.first
end
I think, you need to use API::Topic.search(params[:actor])
