I got this type of query
query {
searchRandom (param : MyObjectClass){
city
}
}
How may I set param with the type of MyObjectClass and pass it in the query? To be able to test here?
Use the following query.
query getData($param: MyObjectClass){
searchRandom(param: $param)
city
}
And then go to query variables tab in Graphiql and pass the variable data like this. You have not mention the data types included in MyObjectClass. So use this as an example:
{
"param": {"country": "England", "population": "High" }
}
Then the data should be returned as expected.
--- Additionally ---
If you are running the server, make sure you have set the followings.
You need to create a input object in the GraphQL schema.
input MyObjectClass {
country: String
population: String
}
Then in the resolver you have to pass the object as the argument. (Assuming you are using JavaScript)
const resolvers = {
Query: {
searchRandom: (parent, { param }) => {
var query_data = param
...//your code
return city_name;
},
},
I am not sure whether this addresses your question or not. I hope this answer helps though.
First, I will show the state stored in mongodb.
As you can see, it is a structure with a list called replies in a list called comments. And inside replies there is an array called likes.
comments : [
Object1 : {
replies : [
likes : [
0 : {},
1 : {}
]
]
},
Object2 : {
replies : [
likes : [
0 : {},
1 : {}
]
]
}
]
What I want to do here is to insert/subtract a value only from the likes array inside a specific replies structure. I'm currently using Spring boot and have tried the following:
Query query = new Query();
Criteria criteria = Criteria.where("_id").is(new ObjectId(postId))
.andOperator(Criteria.where("comments")
.elemMatch(Criteria.where("_id").is(new ObjectId(commentId))
.andOperator(Criteria.where("replies")
.elemMatch(Criteria.where("_id").is(new ObjectId(replyId)))
)
)
);
query.addCriteria(criteria);
Update update = new Update();
if (state) {
// remove user id
update.pull("comments.$[].replies.$.likes", new ObjectId(userId));
} else {
// add user id
update.push("comments.$[].replies.$.likes").value(new ObjectId(userId));
}
mongoTemplate.updateFirst(query, update, MyEntity.class);
It is an operation to add or remove userId according to boolean state. As a result of the attempt, up to a specific comment is found, but userId is unconditionally entered in the first likes list of the replies list inside the comment. What I want is to get into the likes list inside a specific reply. Am I using the wrong parameter in update.push()? I would appreciate it if you could tell me how to solve it.
Not a direct answer to your question as I'm not experienced with spring's criteria builder, but here's how you would do it in mongo directly, which might help you to figure it out:
You could define arrayfilters allowing you to keep track of the corresponding indices of each comments and replies. You can then use those indices to push a new object at the exact matching indices:
db.collection.update({
_id: "<postId>"
},
{
$push: {
"comments.$[comments].replies.$[replies].likes": {
_id: "newlyInsertedLikeId"
}
}
},
{
arrayFilters: [
{
"comments._id": "<commentId>"
},
{
"replies._id": "<replyId>"
}
]
})
Here's an example on mongoplayground: https://mongoplayground.net/p/eNdDXXlyi2X
Document stored in mongodb:
{
"CNF_SERVICE_ID":"1",
"SERVICE_CATEGORY":"COMMON_SERVICE",
"SERVICES":[{
"SERVICE_NAME":"Authentication Service",
"VERSIONS":[{
"VERSION_NAME":"AuthenticationServiceV6_3",
"VERSION_NUMBER":"2",
"VERSION_NOTES":"test",
"RELEASE_DATE":"21-02-2020",
"OBSOLETE_DATE":"21-02-2020",
"STATUS":"Y",
"GROUPS":[{
"GROUP_NAME":"TEST GROUP",
"CREATED_DATE":"",
"NODE_NAMES":[
""
],
"CUSTOMERS":[{
"CUSTOMER_CONFIG_ID":"4",
"ACTIVATION_DATE":"21-02-2020",
"DEACTIVATION_DATE":"21-02-2020",
"STATUS":"Y"
}]
}]
}]
}
]
}
Now, I need to add another customer json to the array "CUSTOMERS" inside "GROUPS" in the same document above. The customer json would be like this:
{
"CUSTOMER_CONFIG_ID":"10",
"ACTIVATION_DATE":"16-03-2020",
"DEACTIVATION_DATE":"16-03-2021",
"STATUS":"Y"
}
I tried this:
Update update = new Update().push("SERVICES.$.VERSIONS.GROUPS.CUSTOMERS",customerdto);
mongoOperations.update(query, update, Myclass.class, "mycollection");
But, I am getting the exception: org.springframework.data.mongodb.UncategorizedMongoDbException: Command failed with error 28 (PathNotViable): 'Cannot create field 'GROUPS' in element
[ EDIT ADD ]
I was able to update it using the filtered positional operator. Below is the query I used:
update(
{ "SERVICE_CATEGORY":"COMMON_SERVICE", "SERVICES.SERVICE_NAME":"Authentication Service", "SERVICES.VERSIONS.VERSION_NAME":"AuthenticationServiceV6_3"},
{ $push:{"SERVICES.$[].VERSIONS.$[].GROUPS.$[].CUSTOMERS": { "CUSTOMER_CONFIG_ID":"6", "ACTIVATION_DATE":"31-03-2020", "STATUS":"Y" } } }
);
Actually, this query updated all the fields irrespective of the filter conditions. So. I tried this but I am facing syntax exception. Please help.
update(
{"SERVICE_CATEGORY":"COMMON_SERVICE"},
{"SERVICES.SERVICE_NAME":"Authentication Service"},
{"SERVICES.VERSIONS.VERSION_NAME":"AuthenticationServiceV6_3"}
{
$push:{"SERVICES.$[service].VERSIONS.$[version].GROUPS.$[group].CUSTOMERS":{
"CUSTOMER_CONFIG_ID":"6",
"ACTIVATION_DATE":"31-03-2020",
"STATUS":"Y"
}
}
},
{
multi: true,
arrayFilters: [ { $and:[{ "version.VERSION_NAME": "AuthenticationServiceV6_3"},{"service.SERVICE_NAME":"Authentication Service"},{"group.GROUP_NAME":"TEST GROUP"}]} ]
}
);
Update: April 1,2020
The code I tried:
validationquery.addCriteria(Criteria.where("SERVICE_CATEGORY").is(servicedto.getService_category()).and("SERVICES.SERVICE_NAME").is(servicedetail.getService_name()).and("SERVICES.VERSIONS.VERSION_NAME").is(version.getVersion_name()));
Update update=new Update().push("SERVICES.$[s].VERSIONS.$[v].GROUPS.$[].CUSTOMERS", customer).filterArray(Criteria.where("SERVICE_CATEGORY").is(servicedto.getService_category()).and("s.SERVICE_NAME").is(servicedetail.getService_name()).and("v.VERSION_NAME").is(version.getVersion_name()));
mongoOperations.updateMulti(validationquery, update, ServiceRegistrationDTO.class, collection, key,env);
The below exception is thrown:
ERROR com.sample.amt.mongoTemplate.MongoOperations - Exception in count(query, collectionName,key,env) :: org.springframework.dao.DataIntegrityViolationException: Error parsing array filter :: caused by :: Expected a single top-level field name, found 'SERVICE_CATEGORY' and 's'; nested exception is com.mongodb.MongoWriteException: Error parsing array filter :: caused by :: Expected a single top-level field name, found 'SERVICE_CATEGORY' and 's'
This update query adds the JSON to the nested array, "SERVICES.VERSIONS.GROUPS.CUSTOMERS", based upon the specified filter conditions. Note that your filter conditions direct the update operation to the specific array (of the nested arrays).
// JSON document to be added to the CUSTOMERS array
new_cust = {
"CUSTOMER_CONFIG_ID": "6",
"ACTIVATION_DATE": "31-03-2020",
"STATUS": "Y"
}
db.collection.update(
{
"SERVICE_CATEGORY": "COMMON_SERVICE",
"SERVICES.SERVICE_NAME": "Authentication Service",
"SERVICES.VERSIONS.VERSION_NAME": "AuthenticationServiceV6_3"
},
{
$push: { "SERVICES.$[s].VERSIONS.$[v].GROUPS.$[g].CUSTOMERS": new_cust }
},
{
multi: true,
arrayFilters: [
{ "s.SERVICE_NAME": "Authentication Service" },
{ "v.VERSION_NAME": "AuthenticationServiceV6_3" },
{ "g.GROUP_NAME": "TEST GROUP" }
]
}
);
Few things to note when updating documents with nested arrays of more than one level nesting.
Use the all positional operator $[] and the filtered positional
operator $[<identifier>], and not the $ positional operator.
With filtered positional operator specify the array filter conditions
using the arrayFilters parameter. Note that this will direct your update to target the specific nested array.
For the filtered positional operator $[<identifier>], the
identifier must begin with a lowercase letter and contain only
alphanumeric characters.

Thanks to #prasad_ for providing the query. I was able to eventually convert the query successfully to code with Spring data MongoTemplate's updateMulti method. I have posted the code below:
Query validationquery = new Query();
validationquery.addCriteria(Criteria.where("SERVICE_CATEGORY").is(servicedto.getService_category()).and("SERVICES.SERVICE_NAME").is(servicedetail.getService_name()).and("SERVICES.VERSIONS.VERSION_NAME").is(version.getVersion_name()));
Update update=new Update().push("SERVICES.$[s].VERSIONS.$[v].GROUPS.$[].CUSTOMERS", customer).filterArray(Criteria.where("s.SERVICE_NAME").is(servicedetail.getService_name())).filterArray(Criteria.where("v.VERSION_NAME").is(version.getVersion_name()));
mongoOperations.updateMulti(validationquery, update, ServiceRegistrationDTO.class, collection, key,env);
mongoTemplateobj.updateMulti(validationquery, update, ServiceRegistrationDTO.class, collection, key,env);
I cannot get a WHERE statement working with an 'OR' condition in Strapi via graphql playground.
I would like to return all results where either the 'title' OR 'content' fields contain the search_text.
I have tried the following:
articles(where: {
or: [
{"title_contains" : "search_text"},
{"content_contains" : "search_text"}
]
}) {
title
content
}
but an error is returned.
ERROR: "Your filters contain a field 'or' that doesnt appear on your model definition nor it's relations.
Some statements that work (but not what I am after):
where: { "title_contains" : "sometext" }
working, but behaves as an 'AND'
where: {
"title_contains" : "search_text",
"content_contains" : "search_text"
}
As of July it's possible to do it like this
(where: { _or: [{ someField: "1" }, { someField2: "2" }] })
The workaround here is to create a custom Query and make a custom database query that matches your need.
Here is how to create a custom GraphQL query:
https://strapi.io/documentation/3.0.0-beta.x/guides/graphql.html#example-2
To access the data model, you will have to use strapi.models.article (For an Article model) and inside this variable, you will access to native Mongoose or Bookshelf function. So you will be able to query with an OR
I have a table in rethinkdb where each row has following structure -
{
'name':'clustername',
'services':[
{
'name':'service1'
},
{
'name':'service2'
}
]
}
I am running a query to filter service2 object like this
r.table('clusters').filter({"name": "clustername"})
.pluck('services').filter((service) => {
return service("name").match('service2')
})
But this is not returning anything: No results were returned for this query
Can anyone tell why this is happening?
pluck returns sequence, so this query:
r.table('clusters').filter({"name": "clustername"}).pluck('services')
will return:
{
"services": [
{
"name": "service1"
} ,
{
"name": "service2"
}
]
}
You need get services field from it, it will return array with services field of items found by filter.
And after that you need to use your second filter on each item by using map.
So, correct query:
r.table('clusters').filter({"name": "clustername"}).pluck('services')("services").map(item => {
return item.filter(service => {
return service("name").match("service2");
});
})
