phoenix-in-action's Introduction

Phoenix in Action

Thanks for checking out the code listings and snippets from Phoenix in Action!

As the book goes through the MEAP process, I will be attempting to keep this repo up to date with what is available in MEAP. The organization will be by chapter. Inside each chapter directory, you'll be able to see how the project code should look by the end of that specific chapter.

Please let me know if you spot any errors or if any listing does not work for you.

Buy the book!

If you don't already have the book, you can buy it from Manning.

auction_umbrella/apps/auction/config/config.exs does not exist

I followed your book, everything was going well till page no 121. In the 5th paragraph, you say config.exs exists in auction_umbrella/apps/auction/config/ but it doesnt exist at all. I am stuck here and need help.

I am using elixir 1.13.0 and erlang/OTP 24. I tried downloading the config folder from this repo and keep in auction_web but still it doesnt work.

I tried to downloading ch6 folder from this repo and start from there, but when I run mix ecto.create, I get an error

`warning: could not find Ecto repos in any of the apps: [:auction, :auction_web].

You can avoid this warning by passing the -r flag or by setting the
repositories managed by those applications in your config/config.exs:

    config :auction, ecto_repos: [...]`

Figure 2.7 has a Typo

This issue is about the book itself (downloaded the latest version as an epub).

In figure 2.7, alias and import statements on the right have the same typo (Math.Finance.Mortagage). The typo is the additional a in Mortagage which should be removed to match the module name Math.Finance.Mortgage

Bug - 6.2 Creating a new Phoenix application pg 109

Hi,

I'm using the latest Phoenix v1.4.6

The command mix phx.new.web auction_web --no-ecto. does not work.

When i run the mix.server command, after running above, this is what i get ---

$ mix phx.server
Compiling 11 files (.ex)
Generated auction_web app

23:48:11.383 [info] Access AuctionWeb.Endpoint at http://localhost

And it just hangs there.

I'm not sure whether this is a bug with the Phoenix framework itself.

Instead i had to use the mix phx.new command to get the web app/phoenix working.

Unnecessary migration file

It looks like migration related to posts table creation was created twice.
I'm getting an error while running `mix ecto.migrate

File 20170714201653_create_api_post.exs contains the creation of posts table with timestamps, then you can see another file 20170714172040_create_app_post.exs I think with the right schema.

Backtrace:
