ruby on rails - Validates uniqueness of :link -

-

I have a model whose name has the following validation in my model 

  validates_uniqueness_of: link ,: Case_sensitive = & gt; False

When I put "", it goes well. Now when I put "" (with a trail slatch), it is also accepted as unique but I want it to be invalid, but what is "/" in the end?

I recommend that you submit your url before submitting them in DB and before verification Slash, slash, etc.). 

  validates_uniqueness_of: link ,: case_sensitive => Wrong before_validation: normalize_urls self.link.strip DRF normalize_urls! Self.link.gsub! (/ \ / $ /, '') End

It is not enough that what you were asking, but if you do not store normalized URLs, For changes you will have to ask your DB and it can be expensive quickly.

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'
