I have an app with a basic blog structure. Creating new blogs works perfectly on localhost, but when I try to create a new blog on Heroku I get the following error in my logs:
2018-07-11T21:20:01.863867+00:00 app[web.1]: [2f20a9d7-e0f6-4ab9-b2ac-d6b3a08e8ed0] Command :: file -b --mime '/tmp/819c55b783715f61a2656207b4852b5c20180711-4-140ohfr.jpg' 2018-07-11T21:20:01.872443+00:00 app[web.1]: [2f20a9d7-e0f6-4ab9-b2ac-d6b3a08e8ed0] Completed 500 Internal Server Error in 38ms (ActiveRecord: 0.0ms) 2018-07-11T21:20:01.873180+00:00 app[web.1]: [2f20a9d7-e0f6-4ab9-b2ac-d6b3a08e8ed0] 2018-07-11T21:20:01.873253+00:00 app[web.1]: [2f20a9d7-e0f6-4ab9-b2ac-d6b3a08e8ed0] NoMethodError (undefined method `[]=' for nil:NilClass): 2018-07-11T21:20:01.873285+00:00 app[web.1]: [2f20a9d7-e0f6-4ab9-b2ac-d6b3a08e8ed0] 2018-07-11T21:20:01.873329+00:00 app[web.1]: [2f20a9d7-e0f6-4ab9-b2ac-d6b3a08e8ed0] app/controllers/blogs_controller.rb:48:in `create' 2018-07-11T21:20:01.874027+00:00 app[web.1]: 10.101.219.132 - - [11/Jul/2018:21:19:56 UTC] "POST /blogs HTTP/1.1" 500 1958 2018-07-11T21:20:01.874063+00:00 app[web.1]: http://www.linchpinrealty.com/blogs/new -> /blogs 2018-07-11T21:20:01.874816+00:00 heroku[router]: at=info method=POST path="/blogs" host=www.linchpinrealty.com request_id=2f20a9d7-e0f6-4ab9-b2ac-d6b3a08e8ed0 fwd="68.225.227.137" dyno=web.1 connect=0ms service=5463ms status=500 bytes=2235 protocol=http My blogs#create method is decently simple:
def create @pillars = Pillar.all @blog = Blog.new(blog_params) if current_user.id = 1 @blog.user_id = 2 else @blog.user = current_user end if @blog.save redirect_to @blog, notice: 'Blog was successfully created.' else render :new end end And I have the following permissions:
private # Use callbacks to share common setup or constraints between actions. def set_blog @blog = Blog.friendly.find(params[:id]) end # Only allow a trusted parameter "white list" through. def blog_params params.require(:blog).permit(:title, :teaser, :body, :user_id, :image, :tag_list, :link_text, :link_filename, :pillars_id) end I'm not sure where things are going off the rails (no pun intended). I did see this question where the issue was a database issue. In which case, the only recent change I've made would be in my blogs#show method...even though I have no idea how that would prevent a blog from even saving in the database (which it doesn't):
def show @pillars = Pillar.all @pillar = Pillar.find_by(id: @blog.pillars_id) @related = Blog.where(pillars_id: @blog.pillars_id).where.not(id: @blog.id).limit(4) @comment = @blog.comments.build @comments = Comment.where(blog_id: @blog.id, approved: true) if current_user @user = current_user end end Can anyone see where I'm going wrong?

From the logs and the fact it's working fine on your localhost, it's probably an error to host your tmp image file.
You should take a look at these articles:
Edit:
I just saw you get the same error without an image, but don't you set any default image ?
-> Could you post error logs without uploaded image ?
Edit2:
I went on your website, I updated an image on an existing blog post and it works so it's probably not linked to the image system.
Edit3:
After some tests on your websites, it's the tag_list field which is wrong: you can create some new blog post without tags but as soon as you insert some tags an error is raised.
Ps: Sorry I did not managed to get my tests deleted without routes

Have you checked your migrations on Heroku?
