Question

我是rails的新手，我很感激您的意见。我创建了一个带有自动填充搜索框的应用。当用户输入疾病时，我希望他被重定向到“显示”视图，其中包含有关此疾病的一些信息。自动完成工作正常，但没有重定向。

这是我的完整代码 https://gist.github.com/ollac21/0ab136d46d06e37fb2c2

我的路线

Rails.application.routes.draw do

resources :diseases do
  get :search, :on => :collection
end


root 'diseases#index'
end

我的控制器

class DiseasesController < ApplicationController

before_action :set_disease, only: [:show, :edit, :update, :destroy]


def index
  respond_to do |format|
    format.html
    format.json { @diseases = Disease.search(params[:term]) }
  end
end


def show
end

private
# Use callbacks to share common setup or constraints between actions.
def set_disease
  @disease = Disease.find(params[:id])
end

# Never trust parameters from the scary internet, only allow the white list through.
def disease_params
  params.require(:disease).permit(:name)
end

end

我的观点

<h1> Type any disease to find info about it </h1>

<div class="diseases-search">
<input type="text" id="diseases-search-txt" autofocus>
<div class="results" id="diseases-search-results"></div>
</div>


<script>
$(function() {
new app.Diseases;
});
</script>

我的Javascript

    app.Diseases = function() {
  this._input = $('#diseases-search-txt');
  this._initAutocomplete();
};

app.Diseases.prototype = {
  _initAutocomplete: function() {
    this._input
      .autocomplete({
        source: '/diseases',
        appendTo: '#diseases-search-results',
        select: $.proxy(this._select, this)
      })
      .autocomplete('instance')._renderItem = $.proxy(this._render, this);
  },

  _render: function(ul, item) {
    var markup = [

      '<span class="name">' + item.name + '</span>'

    ];
    return $('<li>')
      .append(markup.join(''))
      .appendTo(ul);
  },

  _select: function(e, ui) {
    this._input.val(ui.item.name);
    return false;
  }
};

另外，我用它来“激励自己” https://github.com/lugolabs/tutorials/tree/master/amazing

我真的很感激一些帮助谢谢！

您可以为控制器中的每个desease生成路由（或json view）并将其添加到json响应中。然后将链接添加到您的标记：

_render: function(ul, item) {
  var markup = [
    // Assuming that item is the disease record
    '<a href='+ item.the_url +'><span class="name">' + item.name + '</span></a>'

  ];
return $('<li>')
  .append(markup.join(''))
  .appendTo(ul);
},
