ngrx docs

[jmls]

• [x] Question

What version of this module are you using?

• [x] 2.1.0

Please add a description for your issue:

Installed the latest version, eager to use the cool ngrx features ... but can't find any docs ... am I going blind ?

:)

[jmls]

so, I tried

./node_modules/.bin/lb-sdk server/server src/app/sdk -n enabled

and

./node_modules/.bin/lb-sdk server/server src/app/sdk -n orm

but both give an error

readline.js:1021
            throw err;
            ^

[jmls]

anyone ? :)

[jonathan-casarrubias]

@jmls .... I think in the following days we will see some docs from @JonnyBGod.. He is quite busy with an upcoming conf, but he will be sending those docs soon.

Cheers Jon

[jmls]

any luck on the docs or the above error ?

[jmls]

my usual weekly bump ;) hoping to understand why I'm getting the error when trying to generate code ...

[jonathan-casarrubias]

@jmls I would like to help more on this but I don't have idea how to use this neither... Lol,

But, the unit tests are working, have you tried to run the test environment and see how @JonnyBGod wired the tests you might understand how it is working

[jmls]

yeah - I understand - but right now my problem is that I can't even get the code to generate, let alone play with and test ;) I'll cross fingers and hope that @JonnyBGod gets sufficiently annoyed by the number of pings and comes to see what all the fuss is about :+1:

[zbarbuto]

FTR I found out today that the error in the OP occurs if your relation names have underscores in them.

The generator performs .split('_').pop() to get the action name which means relations with underscores cause errors.

[jmls]

@zbarbuto thanks for the heads-up . @JonnyBGod , any chance you could have a look at this and the docs ?

[jmls]

except for the fact I have no relations with _ in the name ... dammit ...

[JonnyBGod]

@jmls Can you provide a repo or send me your project to check out what might be causing the problem?

@zbarbuto Thanks for reporting. I will investigate a better way to do it to enable underscores for relation names.

[JonnyBGod]

@zbarbuto you should be able to use underscores in your relation names after https://github.com/mean-expert-official/loopback-sdk-builder/pull/547 is released.

Just make sure you do not use double underscore.

[davkime]

@JonnyBGod is there any plan to allow double underscore methods?

The only reason I ask is because the separators for methods accessing related models is double underscore.

[jmls]

dammit, I guess this was never fixed ? Hit it again, wanting to play with ngrx :)

[jmls]

I've found the base problem - it's when you have a scope then you get this error.

I've fixed it by adding

var targetName = model.sharedClass.ctor.relations[action.name.split('__').pop()] || {} under methodName = action.name.split (line 20 of shared/effects/model.ejs) and replacing all other instances of

model.sharedClass.ctor.relations[action.name.split('__').pop()] with targetName
