I am getting the following exception at the following HQL.
java.util.ArrayList cannot be cast to java.lang.String.
Obviously I'm missing something but can't, can't figure it out. Can somebody please advise?
def methodA(List<String> key1List, List<String> key2List){
def results = DomainX.findAll("from DomainX x where (x.key1 in (:key1_s)) and (x.key2 in (:key2_s))",[key1_s:key1List, key2_s:key2List])
}
The following works but not the above one:
def methodA(List<String> key1List, List<String> key2List){
def results = DomainX.findAll("from DomainX x where (x.key1 in (:key1_s)) and (x.key2 in (:key2_s))",[key1_s:['ABC'], key2_s:['DEF']])
}
It was my mistake. key2List was like [[key2_a], [key2_b]]; GORM was expecting this to be a flattened list [key2_a, key2_b].

I am trying to assert a list using match contains any, match each but it is not working.
def actualList = ["CABLE_MODEM","SET_TOP_BOX","SET_TOP_BOX","CABLE_MODEM","CBE"]
def expectedList = ["CABLE_CARD","SET_TOP_BOX","CABLE_MODEM","MTA","OTHER","IP_SET_TOP_BOX"]
match each actualList contains any expectedList
Basically, every value of the actualList should be any one of the expectedList value. But it is directly comparing the first value of the 2 lists. Kindly help me
I'm not sure I understand the question. But sometimes these crazy assertions are best done in JS:
* def actualList = ["CABLE_MODEM","SET_TOP_BOX","SET_TOP_BOX","CABLE_MODEM","CBE"]
* def expectedList = ["CABLE_CARD","SET_TOP_BOX","CABLE_MODEM","MTA","OTHER","IP_SET_TOP_BOX"]
* def unexpected = actualList.filter(x => !expectedList.includes(x))
* match unexpected == []
Please take the help of a friend who knows JS if the above is not clear.
EDIT: for completeness, here's the "karate style" way to solve this. For more complex custom checks, karate.match() can be used.
* def valid = function(x){ return expectedList.includes(x) }
* match each actualList == '#? valid(_)'
Domain class:
class Transaction {
String roundId
BigDecimal amount
:
}
The SQL we wish to execute the following:
"select sum(t.amount) from transaction t where t.roundId = xxx"
We have been unable to find an example which does not return Transaction rows.
We assume there are two approaches:
Use projections and/or criteria etc? All the examples we have found only return lists of transaction rows, not the sum.
Use raw SQL. How do we call SQL, and get a handle on the BigDecimal it returns?
I tried this:
class bla{
def sessionFactory
def someMethod() {
def SQLsession = sessionFactory.getCurrentSession()
def results = SQLsession.createSQLQuery("select sum(t.credit) from transaction t where t.round_id = :roundId", [roundId: roundId])
But this fails with
groovy.lang.MissingMethodException: No signature of method: org.hibernate.internal.SessionImpl.createSQLQuery() is applicable for argument types: (java.lang.String, java.util.LinkedHashMap)
Also, I have no idea what the return type would be (cant find any documentation). I am guessing it will be a list of something: Arrays? Maps?
==== UPDATE ====
Found one way which works (not very elegant or grails like)
def SQLsession = sessionFactory.getCurrentSession()
final query = "select sum(t.credit) from transaction t where t.round_id = :roundId"
final sqlQuery = SQLsession.createSQLQuery(query)
final results = sqlQuery.with {
setString('roundId', roundId)
list() // what is this for? Is there a better return value?
}
This seems to return an array, not a list as expected, so I can do this:
if (results?.size == 1) {
println results[0] // outputs a big decimal
}
Strangely, results.length fails, but results.size works.
Using Criteria, you can do
Transaction.withCriteria {
eq 'roundId', yourRoundIdValueHere
projections {
sum 'amount'
}
}
https://docs.jboss.org/hibernate/core/3.3/api/org/hibernate/classic/Session.html
Query createSQLQuery(String sql, String[] returnAliases, Class[] returnClasses)
Query createSQLQuery(String sql, String returnAlias, Class returnClass)
The second argument of createSQLQuery is one or more returnAliases and not meant for binding the statement to a value.
Instead of passing your values in the 2nd argument, use the setters of your Query object i.e. setString, setInteger, etc.
results.setInteger('roundId',roundId);
When executing the following piece of code:
def xml = new XmlSlurper().parse(url)
title = rss.chanel.title
rss.channel.item.each {
sql.firstRow("SELECT COUNT(*) FROM news WHERE title = ? ", [it.title])
}
I get the following error:
Invalid argument value: java.io.NotSerializableException
What may cause it?
The problem was that it.title was a NodeChild object.
In order to get the serializable text of this object I had to use it.title.text(). It was quite tricky since I could use print it.title successfully
I want to get the string character from an ObjectId object. I use pymongo.
eg: ObjectId("543b591d91b9e510a06a42e2"), I want to get "543b591d91b9e510a06a42e2".
I see the doc, It says ObjectId.toString(), ObjectId.valueOf().
So I make this code: from bson.objectid import ObjectId.
But when I use ObjectId.valueOf(), It shows:
'ObjectId' object has no attribute 'valueOf'.
How can I get it? Thanks.
ObjectId.toString() and ObjectId.valueOf() are in Mongo JavaScript API.
In Python API (with PyMongo) proper way is to use pythonic str(object_id) as you suggested in comment, see documentation on ObjectId.
ObjectId.toString() returns the string representation of the ObjectId() object.
In pymongo str(o) get a hex encoded version of ObjectId o.
Check this link.
What works for me is to "sanitize" the output so Pydantic doesn't get indigestion from an _id that is of type ObjectId...here's what works for me...
I'm converting _id to a string before returning the output...
# Get One
#router.get("/{id}")
def get_one(id):
query = {"_id": ObjectId(id)}
resp = db.my_collection.find_one(query)
if resp:
resp['_id'] = str(resp['_id'])
return resp
else:
raise HTTPException(status_code=404, detail=f"Unable to retrieve record")
Use str(ObjectId), as already mentined in the comment by #Simon.
#app.route("/api/employee", methods=['POST'])
def create_employee():
json = request.get_json()
result = employee.insert_employee(json)
return { "id": str(result.inserted_id) }
This is an old thread, but as the existing answers didn't help me:
Having run
new_object = collection.insert_one(doc)
I was able to get the ObjectID with the inserted_id property:
print(f"{new_object.inserted_id}")
In python (Pymongo) there's no inbuilt method to do it so iterate over the result you fetched from db and then typecast _id to str(_id)
result = collection.find({query})
for docs in result:
docs[_id] = str(docs[_id])
first you have to assign the Object Id value to a variable
for example:
let objectId = ObjectId("543b591d91b9e510a06a42e2");
then use the toString method like this
let id = objectId.toString();
I'm new to Groovy and Grails. I think this problem probably has an easy answer, I just don't know it.
I have a database table:
id | category | caption | image | link
I have a query that lets me retrieve one row for each distinct item in 'category.'
I'm trying to return a map where each row is an array named by it's category.
e.g., If I select the rows:
[{category='foo', caption='stuff', ...} {category='bar', caption='things', ...}]
I want to be able to:
return [foo:foo, bar:bar]
where:
foo = [caption='stuff', ...]
bar = [caption='things', ...]
Thanks for any help.
You can transform your list using collect in Groovy, however, the result depends on the source data. I could not infer from your post that if you are returning one item per category or multiple.
def ls = Category.list()
def newList = ls.collect {
[(it.category):['caption':it.caption,'image':it.image,'link':it.link]]
}
will result in something like :
[
[bar:[caption:BarCaption-2, image:BarImage-2, link:BarLink-2]],
[bar:[caption:BarCaption-1, image:BarImage-1, link:BarLink-1]],
[bar:[caption:BarCaption-0, image:BarImage-0, link:BarLink-0]],
[foo:[caption:FooCaption-2, image:FooImage-2, link:FooLink-2]],
[foo:[caption:FooCaption-1, image:FooImage-1, link:FooLink-1]],
[foo:[caption:FooCaption-0, image:FooImage-0, link:FooLink-0]]
]
If you have multiple items per each category you probably want to return the list of each.
def bars = newList.findAll { it.containsKey 'bar' }
def foos = newList.findAll { it.containsKey 'foo' }
[foos:foos,bars:bars]
If I understand your question correctly (I think you mean to put ':' instead of '=' for your maps) then I think the following will work. If new to Groovy, you might find the Groovy web console at http://groovyconsole.appspot.com/ useful. You can try snippets of code out easily, like the following:
def listOfMaps = [[category:'foo', caption:'stuff', something:'else'], [category:'bar', caption:'things', another:'thing']]
def mapOfMaps = [:]
listOfMaps.each { mapOfMaps += [(it.remove('category')) : it] }
assert mapOfMaps == [foo:[caption:'stuff', something:'else'], bar:[caption:'things', another:'thing']]
