The title says it all.
If I have something like this:
type Model {
id
name
}
and only specific users should be able to access the ID field. How I can do it?
Same thing if specific users can access only Model > relationship data. How I can hide attributes based on the user capabilities?
You can use #can directive, like:
type Model {
id: ID! #can(...)
}

I'm trying to run a GraphQL query in the AWS AppSync console:
query MyQuery {
getUserInfoById(id: "1234566789") {
account {
id // need this value for getAvailableCourses
}
}
getAvailableCourses(accountId: "", pageNumber: 0) {
data {
id
name
type
}
}
}
Basically I need the value account.id in getUserInfoById for getAvailableCourses. I'm obviously new to GraphQL. How would I go about this?
To the best of my knowledge, there can be two ways you can do this.
You can handle this in your frontend by getting user's id
from the session info and pass it to the other query.
You can also merge these two queries and make it one. You will also have to change the respective fields. Then attach a resolver with AvailableCourses and use $ctx.source.id in the resolver to get further details. Schema would look something like this
type Account {
id : ID!
availableCourses: AvailableCourses
..
}
type AvailableCourses {
name: String!
type: String!
..
}
type Query {
getUserInfoById(id: ID!): Account
}
Using the returned fields as inputs for a second query into your datasource is precisely what field resolvers are for. I can't say for sure since I don't know your schema or access patterns but it looks like you need to make available courses a sub field of the user.
First, Saleor with GraphQL is fantastic. Just love it.
The products we are selling have additional metadata we need to get from Graphql. Out of the box, the Graphql queries work fine, such as:
{
product (id: "UHJvZHVjdDo3Mg==") {
id
name
description
}
}
What I need to do is expose data from my products table with additional columns, such as productInfo1, productInfo2, and productInfo3. This part is easy of course.
However, I am struggling with how to update the Saleor Graphql so I can run a query like the following:
{
product (id: "UHJvZHVjdDo3Mg==") {
id
name
description {
productInfo1
productInfo2
productInfo3
}
}
}
I have been through the Saleor docs, Stack Overflow, and a variety of blogs... I've attempted some logical approaches myself, without any success.
I'm eager to start working on these types of updates for our needs here. Any suggestions or links to "how to" locations would be greatly appreciated!
If you'd like to add subfields to description there is a couple of things you have to do:
Create new description object type which contains the subfields you want, e.g.:
class ProductDescription(graphene.ObjectType):
productInfo1 = graphene.String()
productInfo2 = graphene.String()
productInfo3 = graphene.String()
Set the description field with the new type under Product type:
class Product(CountableDjangoObjectType):
...
description = graphene.Field(ProductDescription)
Add resolver for description under Product type:
def resolve_description(self, info):
return ProductDescription(
productInfo1=self.description,
productInfo2='Some additional info',
productInfo3='Some more additional info',
)
Saleor's GraphQL API is based on the Graphene framework. You can find more about resolvers and object types here: https://docs.graphene-python.org/en/latest/types/objecttypes/#resolvers.
I am developing a Web application using Laravel. For the admin panel, I am using Laravel Nova. What I am trying to do now is that I need to use data from the table which has relationship through another table. To be, clear, see my database structure below.
items
=====
id
name
price
sub_category_id
sub_categories
==============
id
name
parent_category_id
parent_categories
=================
id
name
What I am trying to achieve inside the Nova is that I want to display the parent category name of the item on the item index/list page. The first thing is that I do not want to create custom attribute something like this in the model
protected $appends = [
'parent_category_name'
];
function getParentCategoryNameAttribute()
{
//code here
}
Therefore, there are two solutions I can think of. The first solution is using the HasThrough relationship. But I cannot find it in Nova. So, I cannot use it. The second solution is that overriding the field value on render. Something like this.
Text::make("fieldname")->fillUsing(function($request, $model, $attribute, $requestAttribute) {
//$model->sub_category->parent_category - then I can return a value
return "Parent category name";
})->onlyOnIndex()
But the above code is not working. So, what would be the best approach to handle the has-through relationship in Nova?
Assuming you have defined the relationship sub_category & parent_category properly.
Define the relationship in Item model as below
public function parent_category()
{
return $this->sub_category->parent_category();
}
Then use it in Item resource as below.
BelongsTo::make('Parent Category')
->hideWhenCreating()
->hideWhenUpdating(),
I'm encountering an annoying problem with Laravel and I'm hoping someone knows a way to override it...
This is for a system that allows sales reps to see inventory in their territories. I'm building an editor to allow our sales manager to go in and update the store ACL so he can manage his reps.
I have two related models:
class Store extends Eloquent {
public function StoreACLEntries()
{
return $this->hasMany("StoreACLEntry", "store_id");
}
}
class StoreACLEntry extends Eloquent {
public function Store()
{
return $this->belongsTo("Store");
}
}
The idea here is that a Store can have many entries in the ACL table.
The problem is this: I built a page which interacts with the server via AJAX. The manager can search in a variety of different ways and see the stores and the current restrictions for each from the ACL. My controller performs the search and returns the data (via AJAX) like this:
$stores = Store::where("searchCondition", "=", "whatever")
->with("StoreACLEntries")
->get();
return Response::json(array('stores' => $stores->toArray()));
The response that the client receives looks like this:
{
id: "some ID value",
store_ac_lentries: [
created_at: "2014-10-14 08:13:20"
field: "salesrep"
id: "1"
store_id: "5152-USA"
updated_at: "2014-10-14 08:13:20"
value: "salesrep ID value"
]
}
The problem is with the way the StoreACLEntries name is mutilated: it becomes store_ac_lentries. I've done a little digging and discovered it's the toArray method that's inserting those funky underscores.
So I have two questions: "why?" and "how do I stop it from doing that?"
It has something in common with automatic changing camelCase into snake_case. You should try to change your function name from StoreACLEntries to storeaclentries (lowercase) to remove this effect.
I'm using Mongoid for Ruby. I have queried in my Mongo database before, but forget how it works with Mongo. I have a user model like so:
class User
include Mongoid::Document
field :email, type String
field :crypted_password, type String
...
end
How would I grab all the users or a specific user in my console? Thanks to anyone who can help
use *database
This returns a specific user:
db.getUser("*user")
This returns all users
db.getUsers()
If your class is called User then the underlying MongoDB collection will be users. So you'd say things like:
> db.users.find() // All users
> db.users.find({ field: value }) // Users that match certain conditions
> db.users.findOne({ _id: ObjectId('...') }) // Find one user with a specific id
...
See the find and findOne documentation for further details.
