Postgres Rails 4搜索查询ID或多列

Question

I am working in an app with a basic search form with Heroku, but I can't get my sql query to work properly with PostgreSQL, even though this query worked with MySQL. By the way, I tried to paste the logs from Heroku, but it only says that when you search something it renders 500.html.

Here's my model OrdemDeServico with the search action:

def self.search(search)
   if search
    joins(:cliente).where("clientes.nome LIKE ? OR veiculo LIKE ? OR placa LIKE  ? OR ordem_de_servicos.id = ?", "%#{search}%", "%#{search}%", "%#{search}%", "#{search}")
   else
    where(nil)
   end
  end

I just installed PostgreSQL locally, and it returned this error when searching:

`PG::InvalidTextRepresentation: ERROR:  invalid input syntax for integer: "Augusto"
LINE 1: ... placa LIKE '%Augusto%' OR ordem_de_servicos.id = 'Augusto')

query:

SELECT  "ordem_de_servicos".* FROM "ordem_de_servicos" INNER JOIN "clientes" ON "clientes"."id" = "ordem_de_servicos"."cliente_id" WHERE (clientes.nome LIKE '%Augusto%' OR veiculo LIKE '%Augusto%' OR placa LIKE '%Augusto%' OR ordem_de_servicos.id = 'Augusto')  ORDER BY prazo LIMIT 5 OFFSET 0

I finally worked it out a solution. Those who have the same problem here's my code for the model:

def self.search(search)
    if search
        where("id = ?", search)
        joins(:cliente).where("clientes.nome ilike :q or veiculo ilike :q or placa ilike :q", q: "%#{search}%")
    else
        where(nil)
    end
end
