django和jQuery自动完成无效

本文介绍了django和jQuery自动完成无效的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个表单，其输入作为名称。它搜索数据库中的lastname和firstname字段。当用户键入名称时，我需要自动完成。我建议在这个链接后使用jQuery

但它不工作。我在评论中尝试了所有的建议，nothings的作品。我的模型

  class Pitable（models.Model）：
 pid = models.TextField（db_column ='PID' primary_key = True）＃字段名称小写。 
 lname = models.TextField（blank = True，null = True）
 fname = models.TextField（blank = True，null = True）
 locs = models.TextField（blank = null = True）
 doclist = models.TextField（db_column ='PMIDlist'，blank = True，null = True）＃字段名称小写。 
 
 class Meta：
 managed = False 
 db_table ='PItable'

我的意见：

  import json 
 def get_people（request）：
 if request.is_ajax（）：
q = request.GET.get（'term'，''）
 persons = Pitable.objects.filter（lname__icontains = q）[：20] 
 results =个人的
 
 person_json = {} 
 person_json ['id'] = person.pid 
 person_json ['label'] = person.lname 
 person_json ['value'] = person.lname 
 results.append（person_json）
 data = json.dumps（results）
 #data = json.dumps（list（Pitable.objects。过滤器（lname__icontains = q）.values（'lname'））
 else：
 data ='fail'
 mimetype ='application / json'
 return HttpResponse（data， mimetype）

urls：

  url（r'^ api / get_people /'，views.get_people，name = 'get_people'），

html：

 < link rel =stylesheethref =http://code.jquery.com/ui/1.8.18/themes/base/jquery-ui.csstype = text / cssmedia =all/> 
< script src =http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.jstype =text / javascript> 
< / script> < script src =https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.jstype =text / javascript>< / script> 
 
< script> 
 $（function（）{
 $（＃names）。autocomplete（{
 source：/ api / get_people /，
 minLength：2，
}）; 
}）; 
< / script> 
 ....... 
< div class =ui-widget> 
< label for =names> Drugs：< / label> 
< input id =names> 
< / div>

runserver方面说

 未找到：/ api / get_people / 
 [21 / Oct / 2016 16:36:05]GET / api / get_people /？term = ra HTTP / 1.1404 2065

感谢您的帮助

解决方案

我试过这个：我的网址：

  from django.conf.urls import url 
 from 。导入视图
 app_name ='chinook'
 urlpatterns = [
 url（r'piquery / $'，views.QueryView.as_view（），name ='piquery'），
 url（r'^ api / get_people / $'，views.get_people，name ='get_people'），
]

在function（）中，我更改了

  source：/ api / get_people /，

至

  source：api / get_people /，

现在，runserver输出是

 找不到：/ chinook / piquery / api / get_people / 
 [21 / Oct / 2016 17:55:33]GET / chinook / piquery / api / get_people /？term = ra HTTP / 1.1404 3677

piquery is输入的html页面。我需要使runserver GET / chinook / api / get_people / ...，但如何做？谢谢！

I have a form which has input as name. It search the lastname and firstname field in a database. I need to autocomplete when users type the name. I was suggested to use jQuery following this linkdjango jquery

But it's not working. I tried all the suggestion in the comments, nothings works. My models

class Pitable(models.Model):
pid = models.TextField(db_column='PID', primary_key=True)  # Field name made lowercase.
lname = models.TextField(blank=True, null=True)
fname = models.TextField(blank=True, null=True)
locs = models.TextField(blank=True, null=True)
doclist = models.TextField(db_column='PMIDlist', blank=True, null=True)  # Field name made lowercase.

class Meta:
    managed = False
    db_table = 'PItable'

My views:

import json
def get_people(request):
if request.is_ajax():
    q = request.GET.get('term', '')
    persons = Pitable.objects.filter(lname__icontains = q )[:20]
    results = []
    for person in persons:
        person_json = {}
        person_json['id'] = person.pid
        person_json['label'] = person.lname
        person_json['value'] = person.lname
        results.append(person_json)
    data = json.dumps(results)
    #data = json.dumps(list(Pitable.objects.filter(lname__icontains=q).values('lname')))
else:
    data = 'fail'
mimetype = 'application/json'
return HttpResponse(data, mimetype)

urls:

url(r'^api/get_people/', views.get_people, name='get_people'),

html:

 <link rel="stylesheet" href="http://code.jquery.com/ui/1.8.18/themes/base/jquery-ui.css" type="text/css" media="all" />
 <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript">
 </script> <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js" type="text/javascript"></script>

 <script>
 $(function() {
 $("#names").autocomplete({
source: "/api/get_people/",
minLength: 2,
});
});
</script>
.......
<div class="ui-widget">
<label for="names">Drugs: </label>
<input id="names">
</div>

The runserver side says

Not Found: /api/get_people/
[21/Oct/2016 16:36:05] "GET /api/get_people/?term=ra HTTP/1.1" 404 2065

Thanks for your help

解决方案

I tried this: my urls:

from django.conf.urls import url
from . import views
app_name = 'chinook'
urlpatterns = [
    url(r'piquery/$', views.QueryView.as_view(), name='piquery'),
    url(r'^api/get_people/$', views.get_people, name='get_people'),
]

In function(), I changed

source: "/api/get_people/",

source: "api/get_people/",

Now, the runserver output is

Not Found: /chinook/piquery/api/get_people/
[21/Oct/2016 17:55:33] "GET /chinook/piquery/api/get_people/?term=ra HTTP/1.1" 404 3677

piquery is the html page where the input is. Do I need to make the runserver GET /chinook/api/get_people/..., but how to do it? Thanks!
