Rails LIKE query using mysql -

-

i'm trying query matching substrings. used this:

products = product.where("title ? or description ?", "%#{params[:s_term]}%", "%#{params[:s_term]}%")

which worked great sqlite3 (not worried sql injection right now). however, switched mysql, , when perform query whines encoding::undefinedconversionerror ("\xc2" ascii-8bit utf-8): because of '%' in query. there way me escape or differently in query?

after odesy of encoding "adventures", problem turned out file "importing" database contained strings not utf8 , ascii compatible (the problem character: Â). in function using add strings database, used keep these characters entering db:

thestring.gsub(/\p{ascii}/, '').encode('utf-8')

now can sure in database encoded correctly , searches not return results rails cannot handle encoding reasons!

an alternative may :

thestring.delete!("^\u{0000}-\u{007f}").encode('utf-8')

this alternative did not work me, may work ruby/rails versions.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
