Rails form_for model not working

Question

I'm trying to create a "gif" object using a form_for. However, when I click submit, I just get redirected to my "gif" index page and nothing is created. I want to hit "submit" and have a "gif" created and be redirected to its page.

Here's my controller page

class GifsController < ApplicationController

def index
    if params[:tag]
        @gifs = Gif.tagged_with(params[:tag])
    elsif params[:search]
        @gifs = Gif.search(params[:search])
    else
        @gifs = Gif.all
    end
end

def show
    @gif = Gif.find(params[:id])
end

def new
    @gif = Gif.new
end

def create
    @gif = Gif.new(gif_params)

    @gif.save
    redirect_to @gif
end

private
def gif_params
    params.require(:gif).permit(:title, :link, :recipe, :all_tags, ingredients_attributes: [:id, :name, :_destroy], directions_attributes: [:id, :step, :_destroy])
end

end

Here's my form on the new page

<%= form_for @gif, :as => :gif, :url => gifs_path do |f| %>
 .....
<% end %>

Terminal Output:

If I change the form_for to :gif instead of @gif, it works. However, I need to use @gif for the gem i'm using, coccoon.

Answer 1

What happens when you remove the :as => :gif, :url => gifs_path from your form like so:

<%= form_for @gif do |f| %>
 .....
<% end %>

It's worth a try, I doubt you need that other stuff

UPDATE:

Your console output shows the following:

(0.2ms)  begin transaction
(0.1ms)  rollback transaction

It also shows the following params being passed:

"gif"=>{
  "title"=>"qwe", 
  "link"=>"http://i.imgur.com/AYPJoxS.gif", 
  "ingredients_attributes"=>{
    "1484430976428"=>{
      "name"=>"123", 
      "_destroy"=>"false"
    }
  }, 
  "directions_attributes"=>{
    "1484430978979"=>{
      "step"=>"123", 
      "_destroy"=>"false"
    }
  }
}

Your gif_params method looks fine, so it seems that something is going wrong when you try to save a gif. To figure out what is happening I would go into rails c and do the following:

gif = Gif.create "title"=>"qwe", "link"=>"http://i.imgur.com/AYPJoxS.gif", "ingredients_attributes"=>{ "1484430976428"=>{ "name"=>"123", "_destroy"=>"false" }}, "directions_attributes"=>{ "1484430978979"=>{ "step"=>"123", "_destroy"=>"false" }}

Above we are passing almost exactly the same params to ActiveRecord, and you will hopefully see some kind of error message on screen when you run this code. It might also be worth running: puts gif.errors to drill down. It's strange you're not getting any error messages when you do this in the browser.

I've seen something similar in one of my own projects where I had configured Pundit incorrectly. Not sure if that helps.
