Question

I have been tried the following query and it succeeds (only returns the one record with exact match):

def self.search(query)
    where("name like ?", query)
end

SQL Executed:

SELECT `products`.* FROM `products` WHERE (name LIKE 'Game')

This query also succeeds (It returns multiple records and there are multiple records with the words ‘Game’ in their name):

def self.search(query)
    where("name like ?", "%Game%")
end

SQL Executed:

SELECT `products`.* FROM `products` WHERE (name like '%Game%')

However when I attempt place a wildcard character with interpolation:

def self.search(query)
    where("name like ?", "%#{query}%")
end

SQL Executed:

SELECT `products`.* FROM `products` WHERE (name like '%[\"Game\"]%')

It doesn’t return anything. Knowing me…probably missing a comma or something. Thanks in advance…

Answer 1

You are passing an Array instead of a String.

Try:

def self.search(query)
  where("name like ?", "%#{query[0]}%") unless query.empty?
end

If it succeeds then fix the query input to be sent as string and not an Array.
