按票数对帖子进行排序
大家好，老读者，第一次发帖:)
我有一个包含帖子的应用程序，我正在使用 gemthums_up (rails v. 3.0.7) 为帖子添加投票。我已经为显示前 10 名帖子的帖子实现了名人墙，但我只是不知道如何按投票对帖子进行排序（加减法）。
现在我只是使用：
def wall_of_fame
@posts = Post.tally(
{ :at_least => 1,
:at_most => 10000,
:limit => 10,
:order => 'vote_count desc'
})
end
和耻辱之墙：
def wall_of_fame
@posts = Post.tally(
{ :at_least => 1,
:at_most => 10000,
:limit => 10,
:order => 'vote_count asc'
})
end
但实际上我需要使用 plusminus 方法来排序帖子，而不仅仅是 vote_count ，因为它只是显示我写了一些帖子，而不是得票最多的帖子，或者至少是这样的：
:order => 'votes_for asc'
对于 wall_of_shame
:order => 'votes_against asc'
目前 votes_for 和 votes_against 只能在视图中使用，例如
@post.votes_for
如何在我的帖子控制器中使用它们才能使用它们在 :order => 中？
谢谢。
Hi everybody long time reader, first time poster :)
I have an app with posts and I am using the gem thumbs_up ( rails v. 3.0.7) to add votes to the posts. I have implemented a wall of fame for the posts showing the top 10 posts and I just can't figure out how to sort the posts by votes ( plusminus method).
Now I am just using:
def wall_of_fame
@posts = Post.tally(
{ :at_least => 1,
:at_most => 10000,
:limit => 10,
:order => 'vote_count desc'
})
end
and for the wall of shame:
def wall_of_fame
@posts = Post.tally(
{ :at_least => 1,
:at_most => 10000,
:limit => 10,
:order => 'vote_count asc'
})
end
but actually I need to order the posts using the plusminus method and not just vote_count, because it just shows me some posts, not the ones with the most up votes, or at least something like:
:order => 'votes_for asc'
and for the wall_of_shame
:order => 'votes_against asc'
Currently votes_for and votes_against can be used only in the views like
@post.votes_for
How can I use them in my posts controller to be able to use them in :order => ?
Thank you.

我也面临这个问题，但我从头开始构建了我的投票机制。我最终在视图中对我的帖子进行了排序。所以，我像这样重新排列它们：
这将我的帖子从得票最多到最少得票排序。
祝你好运！

I faced this issue as well, but I built my voting machinery from scratch. I ended up sorting my posts in the views. So, I redered them like this:
This ordered my posts from the most votes to the least votes.
Good Luck!

您只需订购 plusminus：
