Embedding JSON Data into YAML file

I am writing a fixture for my table. And a one of the coloums takes in a JSON string as a value.

The problem is the fixture is not loading failing as:

Fixture::FormatError: a YAML error occurred parsing /home/saurajeet/code/dcbox/test/fixtures/hardware.yml. Please note that YAML must be consistently indented using spaces. Tabs are not allowed. Please have a look at http://www.yaml.org/faq.html
The exact error was:
  ArgumentError: syntax error on line 145, col 73: `  portslist: [{"name":"ob1","port_num":0,"port_type":"network"},{"name":"ob2","port_nu'.....

Any solutions to this.

I believe taking it into quotes should do the trick:

portslist: '[{"name":"ob1","port_type" ... }]'

clarkevans' comment on the accepted answer suggested a better answer for long bits of JSON, because you can wrap the lines. I looked up the block scalar syntax he mentioned, and thought I would include an example here:

portslist: >
  [{"name":"ob1","port_num":0,"port_type":"network"},
  {"name":"ob2","port_nu...

The | is also possible. For example.

MyObject:
  type: object
  example: |
    {
        "id": 54,
        "manufacturer": "ACME",
        "location": "New York",
        "createdAt": "2012-10-01 07:42:35.825565",
        "description": "test",
    }

If you have the string, you can use as simple as Vlad Khomich mentioned:

portslist: '[{"name":"ob1","port_num":0,"port_type":"network"},...]'

If you are using ERB and have an object, you can use to_json and inspect to escape to a JSON string:

portslist: <%= [{name: 'ob1', port_num: 0, port_type: 'network'},...].to_json.inspect %>

And if you have a large JSON specification, you can store it in a separated file and load using Ruby, so you can keep your YAML file clean:

portslist: <%= File.read('/path/to/file.json').inspect %>

For the sake of being complete: In case you're using ActiveRecord::Store, you can load your data simply using YAML representation of the same data, even if it is a JSON store:

one:
  portslist:
    - 
      name: 'ob1'
      port_num: 0
      port_type: 'network'
    - 
      name: 'ob2'
      port_num: 1
      port_type: 'network'

In my table, the column stripe_connect is of type JSONB . In the fixture, here is what worked. Note that the outer single-quotes are necessary, but square brackets are not. Everything between the single quotes is one long line.

 stripe_connect: '{"scope":"read_write", "livemode":false, "token_type":"bearer", "access_token":"sk_test_madeupvalue", "refresh_token":"rt_Ae29madeupvalueyX", "stripe_user_id":"acct_103yZabcdefg", "stripe_publishable_key":"pk_test_0HEOmadeupvalue"}'
