[英]How can I convert Facebooks Graph API JSON data to find a user that already exists in my database?
Alright, Iv'e done some research but still no luck... 好吧,我做了一些研究,但还是没有运气...
I'll explain what I'm trying to do first: 我将首先解释我要做的事情:
I have an app which is sign in through Facebook only. 我有一个仅通过Facebook登录的应用程序。 I would like these users to see a list of their friends that are using my application as well.
我希望这些用户也可以看到他们的朋友列表,这些朋友也在使用我的应用程序。
I have routed users#index
to return a list of users friends that are currently on the application. 我已经路由
users#index
返回当前在应用程序上的用户朋友列表。 This is displayed in JSON Data
. 这显示在
JSON Data
。 This data is returned as follows: "name"=>"Example Name", "id"=>"32938293828393"
. 该数据按以下方式返回:
"name"=>"Example Name", "id"=>"32938293828393"
。 In my database, I store all users Facebook uid's
. 在我的数据库中,我存储了所有用户的
Facebook uid's
。 I'd now like to be able to find a user by matching the returned JSON id
, by matching it with the uid
that iv'e stored in the database. 现在,我希望能够通过匹配返回的
JSON id
,通过将其与存储在数据库中的uid
进行匹配来查找用户。
This is my current users_controller.rb
: 这是我当前的
users_controller.rb
:
def index
@users = current_user.facebook.get_connections("me", "friends")
@value = '{"id":"name"}'
json = JSON.parse(@value).with_indifferent_access
@users.find(params[json[:id] == :uid])
end
and this is my index.html.erb
: 这是我的
index.html.erb
:
<%= @users.each do |user| %>
<%= link_to user.first_name, user %>
<% end %>
Iv'e been trying to do this for the past day with no luck... Done a lot of research. 在过去的一天里,我一直在努力做到这一点,但是运气不好……做了很多研究。 If there is a resource online explaining how to handle this, please drop a link below.

uids = @friends.collect { |f| f["id"] }
registered_friends = User.where('uid IN (?)', uids)
@pals = registered_friends
end
end
And now in my Users/index.html.erb
I now have 现在在我的
Users/index.html.erb

<% @pals.each do |pal| %>
<%= link_to pal.first_name, wall_path(pal.id) %>
