嘿,我一直在做一些改变,我的Django的农业开发ENV,因为你们中的一些建议Django的。 到目前为止,我已经设法配置并使用postgres成功运行它。错误使用Apache和mod_wsgi的

现在我试图运行应用程序使用apache2和mod_wsgi,但我遇到了这个小问题后,我遵循django文档的指导方针。

当我访问本地主机/ MYAPP /任务这个错误引发:

Request Method: GET 
Request URL: http://localhost/myapp/tasks/ 
Exception Type: TemplateSyntaxError 
Exception Value: 

Caught an exception while rendering: argument 1 must be a string or unicode object

然后它{在任务%为T%}突出了一个模板标签,就像这个问题的根源在那里,但它在内置服务器上运行良好。

与该页面相关的视图是真的是简单,只需获取所有Task对象。模板只是将它们显示在一张桌子上。

另外,一些页面呈现确定。 不想用代码填充此问题,因此如果您需要更多信息,我很乐意提供。由于

所以,这里是我的观点:

@login_required 
def tasks(request, msg=''): 
    tasks = Task.objects.all() 
    message = msg 
    return custom_render('user/tasks.html', 
         {'tasks': tasks, 'message':message}, 
         request) 

这里是我的模板:

{% block main_content %} 

{% if message %} 
    <p id="message" class="info"> 
     {{message}} 
    </p> 
{% endif %} 

<a href="{% url GProject.myapp.views.new_task %}">Nueva Tarea</a> 

    <table id="tasks-table" > 
     <thead> 
      <tr> 
       <th colspan="4" >{{tasks|length}} tareas pendientes</th> 
      </tr> 
      <tr> 
       <th>#</th> 
       <th>Proyecto</th> 
       <th>Título</th> 
       <th>Estado</th> 
      </tr> 
     </thead> 
     <tbody> 
      {% for t in tasks %} 
       <tr id="row-{{t.id}}" class="{% cycle 'row-0' 'row-1' %} priority-{{ t.priority }}"> 
        <td width="25"> 
         <a href="{% url GProject.myapp.views.view_task t.id %}">{{t.id}}</a> 
        </td> 
        <td> 
         <a href="{% url GProject.myapp.views.view_task t.id %}">{{t.project}}</a> 
        </td> 
        <td width="400"> 
         <a href="{% url GProject.myapp.views.view_task t.id %}"> 
          {{t.title}} 
         </a> 
        </td> 
        <td>{{t.get_status_display}}</td> 
       </tr> 
      {% empty %} 
       <tr><td>No tasks</td></tr> 
      {% endfor %} 

     </tbody> 
    </table> 
{% endblock main_content %} 

而且,现在我就在这错误

任务模式是这样的:

class Task(models.Model): 

    project = models.ForeignKey(Project) 
    title = models.CharField(max_length=128) 
    description = models.TextField(max_length=1500) 
    effort = models.IntegerField(null=True, blank=True) 
    priority = models.IntegerField(max_length=1, null=True, blank=True, choices=PRIORITY_VALUES) 
    severity = models.IntegerField(max_length=1, null=True, blank=True, choices=SEVERITY_VALUES) 
    asignee = models.ForeignKey(User, blank=True, null=True, related_name='asignee') 
    milestone = models.ForeignKey(Milestone, blank=True, null=True) 
    created_by = models.ForeignKey(User, blank=True, null=True, related_name='created_by') 
    status = models.IntegerField(max_length=1, choices=STATUS_VALUES, default=1) 
    resolution_comment = models.CharField(max_length=1500, null=True, blank=True) #comentario al resolver la task 
    due_date = models.DateField(blank=True, null=True) 
    created_on = models.DateTimeField(auto_now_add = True) 

    #print  
    def __unicode__(self): 
     return self.title 

custom_render:

def custom_render(template_name, data_dict, request): 
    return render_to_response(template_name, 
           data_dict, 
           context_instance=RequestContext(request))

你可以修改Django源代码和打印repr的sql和params? 当代码下devserver和Apache – 2010-03-14 21:45:00

Django不总是指出模板的正确路线。不要太信任它。 – Macke 2010-03-20 18:52:37

只是因为你没有遇到问题运行manage.py runserver命令,和你确实遇到使用mod_wsgi的问题,我会查看数据库权限。

首先,你是否像运行python manage.py runserver一样运行mod_wsgi?如果不是,则需要授予mod_wsgi用户权限。作为一个例子,尝试这样的,其中apache是​​运行mod_wsgi的用户的名称:

sudo su - postgres 
createuser -S -D -R apache 
psql 
< should now be in the psql shell > 
grant all on database < your database name > to apache;

也认为它可能与DB有关,不要做诡计。 – Nacho 2010-03-28 17:34:27
