i have been trying figure out how params method works , i'm bit stuck on process. for example, if user clicks on blog post in index page, guess link_to method calls post controller , show action along block @post = post.find(params[:id]) , goes database find post , view displays it. so missing link seems when post id passed params method? because others explained params , i'm going answer directly question of yours: when post id passed params method i think it's best explained example; see below: say clicked link: /posts/1/?param1=somevalue1&param2=somevalue2 the rails server receives request client wants view get /posts/1/?param1=somevalue1&param2=somevalue2 address. to determine how rails server respond, server first go routes.rb , find matching controller-action handle request: # let's routes.rb contain line # resources :posts # resources :posts above contains many routes. 1 of them below # sake of example, commented above...

is there way relatively update large number of records in sql server 2014, filtering on nvarchar(x) column, when there no index on column? eg. i'd run: update products set active = 1 productbrand = 'brand name' on product table millions of rows, , there no index on productbrand . creation of index takes around 45 minutes , update table bit faster. we want perform operation fastest way possible, creating index takes lots of time. wandering if there other ways using index. (creating index on name column , leaving there of course practice, rebuilding time time) check product table, maybe have index on productbrandid, if not, can create new tmpproduct table same structure , default 1 in "active" field. insert registers new table drop original table , rename tmpproduct product you must ensure triggers , references recreated
