Installation

To start your new Phoenix application you have to:

0. Copy and edit example dev config:

    cp config/dev.example.exs config/dev.exs
   

1. Install dependencies with mix deps.get

2. Run the migrations mix ecto.migrate LambdaDays.Repo

3. Start Phoenix router with mix phoenix.server

4. Kill it with Ctrl-C Ctrl-C

5. You can also start Phoenix with interactive Elixir shell iex -S mix phoenix.server

6. Add first user to database:

    admin = %LambdaDays.User{admin: true, email: "admin@lambdadays.org", password: "admin", username: "admin"}
    LambdaDays.Repo.insert admin
   

7. Enjoy.

Now you can visit localhost:4000 from your browser.

Goals

• Learn basic elixir.
• Create admin and non-admin users.
• Provide authentication
• Provide API for MongooseIM auth
• Enable adding talks from Lambda Days
• Enable rating talks by users and external API
• Integrate with chat and streaming

Using Talk Api

Indexing all talks

To take all talks from the database just go to the page: talk_api/index. Eg.

curl http://localhost:4000/talk_api/index

Sample response:

{
  "talks":
    [
      {
        "id":1,
        "title":"sample_title",
        "description":"sample_description"
        "plus_votes":0,
        "zero_votes":0,
        "minus_votes":0,
      },
      {
        "id":2,
        "title":"sample_title_2",
        "description":"sample_description_2"
        "plus_votes":0,
        "zero_votes":0,
        "minus_votes":0,
      }
    ]
}

Add rate for the talk

Prepare file request.txt with content:

{
  "id":1,
  "plus_votes":1,
  "zero_votes":2,
  "minus_votes":4
}

and try to update talk using talk_api/update REST api:

curl -X POST -d @request.txt http://localhost:4000/talk_api/update --header "Content-Type:application/json"

The result should be similar to the following:

{
  "talk":
    {
      "id":1,
      "title":"sample_title",
      "description":"sample_description"
      "plus_votes":1,
      "zero_votes":2,
      "minus_votes":4,
    }
}
