How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you

beer. See what you have written on controller isparams.require(:beer)which means the params hash has a key namedbeerand the attributes to permit are inside it. In yourJSONrequest you have this:"beer"=>{"id"=>213, "name"=>"Amber", "brewery_id"=>16}from whichidis not permitted so it is showingUnpermitted parameters: id. Of the rest it don't cares whatever you are sending. Because rails will use the attributes insidebeerto create/update it.def beer_params params.require(:beer).permit(:name, :brewery_id, :style_ids => []) endI call this from my update and create functions.
