问题
I have defined a permits field for a couchdb document like below. I cannot access permits content by *.permits.db I wonder if anybody knows how I can do that.
回答1:
The cause of your problem is that the value of the permits attribute is badly formatted. You have a string rather than an object.
Change:
"{db: ['TEL', 'PPT',]}"
With:
{"db": ["TEL", "PPT"]}
Please note that if your JSON is not formatted correctly (see JSON specification), it will be automatically turned by CouchDB admin interface into a string. Therefore remember:
- to use double quotes around object keys,
- to use double quotes around object values,
- not to use a comma at the end of an array.
