rubygems - Rails optional gem config -

-

When you want to use a gem for development / testing, what do you do to other gods Do not want to use use? Currently 

  requires 'redgreen' rescue load error and

in test_helper.rb and no gem configs , But it seems like a cruel approach, although one functional one I want to do something like the following: 

  config.gem "redgreen",: Optional = & gt; True

any other suggestions? Or should I just sell those beautiful superficial gems? ...

Edit

To be clear, I'm only talking about specific gems such as red buck, which In fact, they are not used in functional codes, but there is no need to sell them except to avoid the conditional requirement of coding only in process .

I gave the same answer

ex>

then

bundle - together -N V = Scott

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
