I have a simple rest call on a lookup field:
_api/web/lists/getbytitle('Planning')/items(1)/?$select=Surveyor
however this returns 400, i know the field is definitely in the Planning list and it is a site column,
I do however, see SurveyorId, but i cant expand this.
Sorry for little information, thanks in advance.
does this field require expansion? if so make sure to try:
_api/web/lists/getbytitle('Planning')/items(1)/?$select=Surveyor/Title&$expand=Surveyor/Title

Sorry if this is a "stupid" question, but I am new to Apex.
I made 2 processes on the create button: one is to insert into the department table and the other one to send an email with some info, among them the department too.
I made an email template and I want to display the department name, not the id which is inserted into the table. So I thought, that maybe I can do that with a function, like in the picture attached(get_department_by_id - returns the name of a department).

The help function in the builder usually gives enough info. Here is the help for "Placeholder values"
So only Application, Page Items and System Variables are allowed.
Note: There are multiple places in APEX where you can pass a number of arguments (links, branches, etc) but nowhere the use of functions is allowed.
This is how it worked for me.
I created a computation, with the computation of type "Expression" with source get_department_by_id(:P7_ID_DEPARTMENT) and Condition Type "Request = Expresion 1" with source the name of the button(ex.create).
Thank you Koen Lostrie for the guidance!
One of the advantage of Github Search v4 (GraphQL) over v3 is that it can selectively pick the fields that we want, instead of always getting them all. However, the problem I'm facing now is how to get certain fields.
I tried the online help but it is more convolution to me than helpful. Till now, I'm still unable to find the fields for size, score and open issues for the returned repository(ies).
That's why I'm wondering if there is a way to get them all, like Select * in SQL. Thx.
GraphQL requires that when requesting a field that you also request a selection set for that field (one or more fields belonging to that field's type), unless the field resolves to a scalar like a string or number. That means unfortunately there is no syntax for "get all available fields" -- you always have to specify the fields you want the server to return.
Outside of perusing the docs, there's two additional ways you can get a better picture of the fields that are available. One is the GraphQL API Explorer, which lets you try out queries in real time. It's just a GraphiQL interface, which means when you're composing the query, you can trigger the autocomplete feature by pressing Shift+Space or Alt+Space to see a list of available fields.
If you want to look up the fields for a specific type, you can also just ask GraphQL :)
query{
__type(name:"Repository") {
fields {
name
description
type {
kind
name
description
}
args {
name
description
type {
kind
name
description
}
defaultValue
}
}
}
}
Short Answer: No, by design.
GraphQL was designed to have the client explicitly define the data required, leading to one of the primary benefits of GraphQL, which is preventing over fetching.
Technically you can use GraphQL fragments somewhere in your application for every field type, but if you don't know which fields you are trying to get it wouldn't help you.
I am new to cassandra (started learning on my own interest few days back) and looking for help for the below problem.
I have a Cassandra table "User" and a ListColumn "interests extends ListColumn[String]".
Now, I want to fetch all users with an interest, say "playing".
like: select from user where interests.contains("playing")!
I scanned through the ListColumn api but not able to find any. Also, searched in google but no such helpful posts.
Any help guys please... Thanks in Advance :)
So there is contains among operators and here is an example how to use it. It looks like that it should work as any other operator, so just go for database.userTable.select.where(_.interests contains "playing").fetch() - of course, depending on your conventions.
This is possible with a secondary index on a collection column, which only works with a Set column, and not with a List.
Bottom line:
object interests extends SetColumn[String](this) with Index[Set[String]]
And then you can execute the following:
select.where(_.interests contains "test").fetch()
You can also use multiple restrictions if you allow filtering.
select.where(_.interests contains "test")
.and(_.interests contains "test2")
.allowFiltering()
.fetch()
The above will only match if both interests are found in a record.
There have recently been several questions posted on Facebook.SO using CONTAINS() in the WHERE clause. It seems to work like the Graph API search function, AND functions as an indexed field. All great things for the FQL developer.
SELECT name,
username,
type
FROM profile
WHERE CONTAINS("Facebook")
However, the only official mention of the CONTAINS function appears in the unified_thread documentation. It is mentioned in passing, as a way to search for text contained in a message. It also appeared in this fbrell code sample.
But Contains doesn't seem to be a straightforward search. For example, this query:
SELECT name
FROM user
WHERE CONTAINS("Joe Biden")
returns "Joe Biden" and also "Joseph Biden" and "Biden Joe". But it also returns "Joe Scardino", "Lindsay Noyan" and "Mehmad Moha" among others. What relationship do these people have with the VP of the USA? They aren't my friends, so I'll never know.
There also appears to be the ability to pass CONTAINS a field to search on, however changing the end of my first query to `CONTAINS("Facebook", name) returns an OAuth error:
(#615) 'name' is not a valid search field for the profile table.
In my not-so rigorous testing, I have yet to find a field/table combination that does not return this error.
So what is this mystery function? How does it work? Can it allow us to do things to date impossible in FQL like traversing arrays and filtering data stored in strings?
An answer here would be great, but a description on an FQL functions & methods reference page on the official developer documentation site would be better still.
I don't think that a have any great answers here, but I can give a workaround for the issue of returning unrelated names- which I suspect is because people have made public posts about Joe Biden, liked him, or so on. If you do the following:
SELECT name
FROM user
WHERE CONTAINS("Joe Biden")
AND strpos(lower(name),lower("Joe Biden")) >=0
You will get a resultset that only contains the right names- though it removes the advantage of also returning Joseph Biden, etc. etc.
My personal point of pain is that CONTAINS() appears to work with partial strings (e.g. "Joe Bide") on the profile table, but not on the user table. Very frustrating.
How can I write a query with ormlite instead of using .create or any other thing like that? Can you please show me how for this simple example :
SELECT name FROM client
EDIT since I can't answer myself :
I guess I had to search a little more , anyway I found how to do it with the QueryBuilder like this :
newDao.query(newDao.queryBuilder().where.eq("name",valueofname)
If someone knows how to write the full query that would be great , otherwise , I'll stick with this solution
How can I write a query with ormlite instead of using .create or any other thing like that?
Goodness, there are tons of documentation about how to do this on the ORMLite site. Here's the section on the query builder.
I'm not sure what you mean by "full query" but your example will work with some tweaks:
List<...> results = newDao.queryBuilder().where().eq("name",valueofname).query();
It does not make sense to just return the name since the Dao hierarchy is designed to return the specific Client object. If you just want the name the you can specify the name column only to return:
... clientDao.queryBuilder().selectColumns("name").where()...
That will return a list of Client objects with just the name field (and the id field if it exists) extracted from the database.
If you just want the name strings then you can use the RawResults feature.
