activerecord - Rails relational issue - Find user's next outing -


I have an outgoing table, which basically has some information about an 'outgoing'.

In the form of just a note, there are many employees outside, therefore the outward_ID of the employees table

Now, I need the user's Next Find out, like in the first outing where outing.start_time & gt; time. Now I have found in my user.rb model: 

  is_im: crew_users_maya: crews ,: through = & gt; : Crew_users have_many: outings ,: through = & gt; : Crews

And when I try to do this: 

  & gt; & Gt; Users.find (1) .outings

I get this error: 

  ActiveRecord :: Statement invalid: Mysql :: error: unknown column 'crews. Where in 'user_id': 'selection' outing. * Out of 'Outgoing' INNER, `` Outgoing `` `` `` `` crews```_outing_id. ((`Crews`.user_id = 1))

Any ideas? Like I said, my goal is to get the user's next out of the present time, so it can be very good to know about it!

If you are doing a double : through , then you try this And can reverse, by filtering outing records instead. For this, the SQL will look something like this: 

  is excluded from SELECT outings.id. Crews.id = outings.crew_id crews_users.crew_id = crews_users on crews.id where crews_users user_id =? And start_time & gt; = NOW () ORDER BY created_at LIMIT 1

There is a quick and dirty view to run this and to remove the outing_id value, then Outing.find with.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
