铁路上的无线电按钮状况红宝石
原标题:Radio button condition ruby on rails

我对这个代码有些问题。 我试图创建“ 提前” 搜索我的数据库。 请求两种类型的数据( 胶片和位置 ) 。 地点一工作完美, 并展示了所有靠近某个位置的电影院。 但是, 如果以电影的具体名字进入电影院, 是否有可能这样做?

Location Controller:
if params[:allcinemas].checked?
  if params[:search].present?
    @locations = Location.near(params[:search], 10, :order => :distance)
    @title = "Search Results:"
  else
    @locations = Location.joins(:cinema).order("cinemas.name").all
    @title = "Locations of Cinemas"   
  end
elsif params[:allmovies].checked?
  if params[:search].present?
    @films = Film.near(params[:search], :order => :title)
  else
    @films = Film.find(:all, :order => "title") 
  end

这是用于位置的 Show. Html. erb

show.html.erb
<p>
 <%= text_field_tag :search, params[:search] %>
 <%= submit_tag "Search Nearby Cinemas", :name => nil %>
 <br><%= radio_button_tag  allcinemas ,  cinemas , true %> Cinemas
 <br><%= radio_button_tag  allmovies ,  movies  %> Movies
</p>
问题回答

您的 radio_ button_tags 应该使用相同的名称, 比如 :

<%= radio_button_tag radio_input , cinemas , true %> Cinemas
<%= radio_button_tag radio_input , movies %> Movies

现在, 在您的控制器 radio_ input. checked 中?? 将总是返回真实的, 因为您默认了选中的选项 。 所以, 而不是此检查 : < code>if parems[: allcenemas]. checked?

check for the value returned by params[:radio_input]:
if params[:radio_button] == cinemas
#your logic to handle cinemas
else
#your logic for movies

那应该能解决你的问题
