PG::DatatypeMismatch: ERROR: column "score" is of type integer but expression is of type text

Question

Here is my code:

    factors.each do |f|
      factor_score_var = "factorScore_#{f.id}"
      params['score'] = params[factor_score_var]
      new_scorecard.scorecard_scores.create(params.permit(:score))
    end

Here is the error:

PG::DatatypeMismatch: ERROR: column "score" is of type integer but expression is of type text at character 98 HINT: You will need to rewrite or cast the expression.

I have tried casting the score param with 'to_i' etc.. :

params['score'] = params[factor_score_var].to_i

But I just keep getting the same error.

I have confirmed that :score is holding a number (I still get this error if I set the var to a number manually), but I still get this error.

Database is Postgress.

Any suggestions greatly appreciated.

Answer 1

I found the problem.

When I originally created the migration, this field was type text. I then did db:rollback and re-ran it with this field being an integer. Event though I reran the migration, rails must have still been treating it as a text.

All I needed to do was restart the rails server and all worked fine.
