小编ham*_*dam的帖子

我正在使用带有Bootstrap的simple_form,我希望我的"记住我"复选框位于标签的左侧,如Twitter Bootstrap文档中所示:http://twitter.github.com/bootstrap/base- css.html#形式

我的表单代码如下所示:

<%= simple_form_for(resource, :as => resource_name, :url => session_path(resource_name), :html => { :class => 'well'}) do |f| %>
    <%= f.input :email %>
    <%= f.input :password %>
    <%= f.input :remember_me, :as => :boolean if devise_mapping.rememberable?  %>

    <%= f.button :submit, "Sign In" %>

<% end %>

结果是复选框顶部的"记住我"标签.

我搞砸了什么？

我正在努力实现图书馆MaybeT的精神mtl.使用这种非编译解决方案:

{-# LANGUAGE FlexibleInstances, MultiParamTypeClasses, UndecidableInstances #-}

import Control.Monad
import Control.Monad.Trans
import Control.Monad.State

newtype MaybeT m a = MaybeT { runMaybeT :: m (Maybe a) }

instance (Monad m) => Monad (MaybeT m) where
    x >>= f = MaybeT $ runMaybeT x >>= maybe (return Nothing) (runMaybeT . f)
    return a = MaybeT $ return (Just a)
    fail _ = MaybeT $ return Nothing

instance MonadTrans MaybeT where
     lift m = MaybeT (liftM Just m)

instance …

我有这个异步Celery任务调用：

update_solr.delay(id, context)

其中id是整数，上下文是Python字典。

我的任务定义如下：

@task
def update_solr(id, context):
    clip = Clip.objects.get(pk=id)
    clip_serializer = SOLRClipSerializer(clip, context=context)
    response = requests.post(url, data=clip_serializer.data)

其中clip_serializer.datadict url是一个表示url的字符串。

当我尝试致电时update_solr.delay()，出现以下错误：

PicklingError: Can't pickle <type 'instancemethod'>: attribute lookup __builtin__.instancemethod failed

任务的两个参数都不是实例方法，所以我很困惑。

任务代码同步运行时，没有错误。

更新：修正了关于传递pk而不是对象的注释。

我正在使用Django REST Framework作为我们的Web API和Solr来支持搜索.Currenlty,在子类中ListAPIView,我重写get_queryset()以获得QuerySetSolr搜索结果:

class ClipList(generics.ListAPIView):
    """
    List all Clips. 

    Permissions: IsAuthenticatedOrReadOnly

    Parameters:
    query -- Search for Clips. EX: clips/?query=aaron%20rodgers
    """
    model = Clip
    serializer_class = ClipSerializer
    permission_classes = (permissions.IsAuthenticatedOrReadOnly,)

    def get_queryset(self):
        params = request.GET
        query = params.get('query', None)

        queryset = Clip.objects.all()

        if query is not None:
            conn = solr.Solr(settings.SOLR_URL)
            sh = solr.SearchHandler(conn, "/select")
            response = sh(query)
            ids = []

            for result in response.results:
                ids.append(result['id'])

            # filter the initial queryset …
