从数据库Django的自动完成 [英] Django autocomplete from db

问题描述

我有这样一个模型：

class Baslik(models.Model):
    user = models.ForeignKey(User, null=True, blank=True)
    title = models.CharField(max_length=50)
    timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
    updated = models.DateTimeField(auto_now_add=False, auto_now=True)
    active = models.BooleanField(default=True)

我想按照这个模型的标题字段模板自动完成输入。我只是想为自动完成标题别的不会为我工作？我觉得应该使用jQuery做，AJAX等。我没有任何关于他们的想法。
有没有办法做到这一点？有没有完全一样的东西的包？
谢谢你。

I want to autocomplete an input in template according to this model's title field. I just want autocomplete for title anything else would not work for me? I think it should be done with jquery, ajax etc. I don't have any idea about them. Is there any way to do this? Is there any packages for exact same thing? Thanks.

推荐答案

UI的自动完成输入工作 pretty好这一点。

ui-autocomplete-input works pretty well for this.

在生成模板列表

<script>
$(function() {
var availableTitles = [
   {% for baslik in basliks %}
      "{{ baslik.title}}" {% if not forloop.last %},{% endfor %}   
   {% endfor %}

];
$( "#tags" ).autocomplete({
  source: availableTitles
});
});
</script>

<div class="ui-widget">
  <label for="tags">Tags: </label>
  <input id="tags">
</div>

修改（以评论）：增加了一个JSON响应;这将需要在两个用户界面，自动完成和自举/ typeahead.js解决方案

EDIT (based on comments): Added a json response; this would be needed in both the ui-autocomplete and bootstrap/typeahead.js solution

import json

from django.http import HttpResponse

def json_response_view(request):
   q = request.GET.get('q', '')
   response_data = Baslik.objects.filter(title__startswith=q).values("title")
   return HttpResponse(json.dumps(response_data), content_type="application/json")
