Ruby w/ Postgres & Sinatra - Query won't order right with parameter??
- by alleywayjack
So I set a variable in my main ruby file that's handling all my post and get requests and then use ERB templates to actually show the pages. I pass the database handler itself into the erb templates, and then run a query in the template to get all (for this example) grants.
In my main ruby file:
grants_main_order = "id_num"
get '/grants' do
erb :grants, :locals => {:db=>db, :order=>grants_main_order, :message=>params[:message]}
end
In the erb template:
db = locals[:db]
getGrants = db.exec("SELECT * FROM grants ORDER BY $1", [locals[:order]])
This produces some very random ordering, however if I replace the $1 with id_num, it works as it should.
Is this a typing issue? How can I fix this? Using string replacement with #{locals[:order]} also gives funky results.
