PostgreSQL全文搜索rails标题和描述

Question

I am trying to search a model with title and description, but having the following error. I want to be able to search title and description and the type of job. Any help will be really appreciated.

PG::DatatypeMismatch: ERROR: argument of OR must be type boolean, not type character varying LINE 1: ...T "refinery_jobs".* FROM "refinery_jobs" WHERE (title OR d... ^ : SELECT "refinery_jobs".* FROM "refinery_jobs" WHERE (title OR description LIKE '%consultant%' AND job_type LIKE '%Contract%') LIMIT 10

Here is my query

results << model.limit(RESULTS_LIMIT).where("title OR description LIKE ? AND job_type LIKE ?","%#{query}%","%#{job_type}%")

Answer 1

your error says that postgresql expects both side of an OR to evaluate to a truthy value. in your sql, this error pertains to the left side of OR which is simply title . just change your query to

where(
  "(title LIKE :query OR description LIKE :query) AND job_type LIKE :job_type",
  query: "%#{query}%",
  job_type: "%#{job_type}%"
)
