Using built-in user model

[Andre197789xh]

Hi,

i try to use the connector with the built-in user model. This works fine (also for other, non built-in models) as long as i do not attach the ACL-model to the couchbase datasource. If i do, i get this error in the explorer console (even when doing requests to other, non built-in models):

{
"error": {
"name": "Error",
"status": 500,
"message": "inq is an unknown key",
"statusCode": 500,
"stack": "Error: inq is an unknown key\n at defaultHandler (C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\strong-remoting\lib\rest-adapter.js:337:15)\n at restErrorHandler (C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\strong-remoting\lib\rest-adapter.js:327:14)\n at Layer.handle_error (C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\express\lib\router\layer.js:58:5)\n at trim_prefix (C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\express\lib\router\index.js:269:13)\n at C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\express\lib\router\index.js:238:9\n at Function.proto.process_params (C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\express\lib\router\index.js:313:12)\n at C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\express\lib\router\index.js:229:12\n at Function.match_layer (C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\express\lib\router\index.js:296:3)\n at next (C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\express\lib\router\index.js:190:10)\n at Layer.handle_error (C:\Users\Andre\WebstormProjects\couchbase-neu\node_modules\loopback\node_modules\express\lib\router\layer.js:54:12)"
}
}

This is my setup for datasources.json and model-config.json:

{
"db": {
"name": "db",
"connector": "memory"
},
"couchbase": {
"connector": "couchbase",
"database": "user_bucket"
}
}

{
...
"User": {
"dataSource": "couchbase",
"public": true
},
"AccessToken": {
"dataSource": "couchbase",
"public": true
},
"ACL": {
"dataSource": "couchbase",
"public": true
},
"RoleMapping": {
"dataSource": "couchbase",
"public": true
},
"Role": {
"dataSource": "couchbase",
"public": true
},
"Note": {
"dataSource": "couchbase",
"public": true
}
}

If i set ACL-datasource back to use the in-memory db everything works fine!? Do you have any clue whats going on?

Hi Andre,

Can you provide a sample of your models? We haven't done extensive testing
of the built-in models attached to couchbase, so there may be some bugs
there. We have primarily tested with non-built-in models. Also, there
will be an update to the connector coming in the next couple of days
hopefully.

Hi Nolan,

thanks for your reply. I just setup a simple project, i did not extend any of the built-in models. I added an own "Note"-model, and as stated before, this works (CRUD) in Couchbase server. Also all the other models (User, AccessToken, RoleMapping, Role) work. Problem is the "ACL"-model, if i set this to use the "couchbase"-datasource nothing works anymore and i get the exception mentioned in my first post.

So this is the only model i defined in the whole project:

{
"name": "Note",
"base": "PersistedModel",
"properties": {
"title": {
"type": "string",
"required": true
}
},
"validations": [],
"relations": {},
"acls": [],
"methods": []
}

Thanks

@ecguardly, I have repoduced this issue however do not know why it is occurring at this point. try cloning this repo and updating the db/model configs to use couchbase - https://github.com/strongloop/loopback-example-access-control. If by chance you come across this issue - https://groups.google.com/forum/#!topic/strongloop/R8XvXvvE1ho, it can be resolved by running npm install loopback-connector-couchbase --save. I got this issue by copying the connector from an another project as opposed to using npm to install.

[nolandubeau]

We are in the process of writing a fix for this as some of the functionality for WHERE clauses was not completed.

Hi, we have published a new version of the connector, which should fix this issue. Please test and let us know.

Hi, thanks, thats great. I have tested it and it works without any flaws so far...Thanks for your efforts!
