No you need to show us what you have done and tell us what is not working.
Which bit is failing? Is it getting to your controller action? Is it
failing running the action? Is it not rendering the next view correctly? Or
what. Show us the specific bit of code that is not working.

 Try it and see, that would be a lot quicker than asking here. If it
doesn't then look in log/development.log and/or the server terminal window
to get a clue as to why not.  When setting the route don't forget that
button_to will use POST.

[Rails] Table already exists error

2016-11-15 Thread eye0rama 


Hi all, 

I have been learning Rails by working through Carneiro and Barazi's 
*Beginning Rails 3*. This has went well despite the fact that I am using 
Rails 4.2.6. I hit a little snag when in chapter 5, which goes over 
associations, I tried to create a has_many association between a user and 
that user's articles, specifically in the code that is supposed to sort the 
user's articles first by order of creation, and then by alphabetical order. 
I fixed this problem, with a little help from the Ruby Talk mailing list, 
with a lambda scope block, as follows in app/models/user.rb: 


class User < ActiveRecord::Base 
 has_one :profile
 has_many :articles, -> { order 'published_at DESC, title ASC' } 
:dependent => :nullify
end

This seemed to work, so I went through the steps listed again, taking a 
stab that I could overwrite everything rather than just starting over.  
When I ran rake db:migrate, I got the following error:

== 20161114230702 CreateArticlesCategories: migrating 
=
-- create_table(:articles_categories, {:id=>false})
rake aborted!
StandardError: An error has occurred, this and all later migrations 
canceled:

SQLite3::SQLException: table "articles_categories" already exists: CREATE 
TABLE "articles_categories" ("article_id" integer, "category_id" integer) 
/home/john/src/ror/blog/db/migrate/20161114230702_create_articles_categories.rb:3:in
 
`change'
ActiveRecord::StatementInvalid: SQLite3::SQLException: table 
"articles_categories" already exists: CREATE TABLE "articles_categories"

`change'
Tasks: TOP => db:migrate
(See full trace by running task with --trace)

I did some poking around in the rails console, and running: 
category.articles.empty?

Returned: NameError: undefined local variable or method `category' for 
main:Object

Is there a way I can fix this without just deleting everything and starting 
over?

 Hi,

 I'm trying to run a method in one of my controllers using a button_to
 command.  How is this accomplished?

 So far, I've got <%= button_to "Add to Cart", action: "add_to_cart" %>
 in my products page

 I defined a add_to_cart in my product controller, and created a route
 for it.

 Am I on the right track?  Will it execute code in that method in that
 controller?

I have just deployed an app on Ubuntu 14.04, Rails 5.0.x, Puma, Nginx. Even
though I have precompiled assets I am getting the following output:



And ofcourse no javascript and css is not loading and returning 404.

In the very same server I have Rails 4.2.x app which works perfectly. Could
any one guess what could have gone wrong?
