Trying to query all users from the user table in Parse.com - java

I am trying to print all users I have saved on Parse database on my screen. But somehow it doesn't work, I can print the data from all other tables expect the users...
I think the problem is somewhere here, because when I change the "Todo" to User table it doesn't work anymore...
mainAdapter = new ParseQueryAdapter<ParseObject>(this, "Todo");
mainAdapter.setTextKey("title");
any suggestions? Thanks!

The user class is special (so are a couple of others) because it's built into the platform. The name doesn't work because the name is private. As you can see _Users is the private name, but you shouldn't use it - you can't guarantee it won't change. The correct way to query is:
ParseQuery<ParseUser> query = ParseUser.getQuery();

I need to display all orders in a recycler view with values name, phoneno.
How can i get the phoneno s?
Several issues in one question . It is quite impossible to have a complete answer in one go .I would advise you to create custom class like Order for example with all data mandatory .Then if you just need to display all orders , i don t think the database structure is the best . You could have Orders:order (with id inside the order class) , or orderBy customerID if you need to handle researches

Unable to retrive Projection/Multi- Relantion field Requests.Custom_SFDCChangeReqID2 using versionone java sdk

I have been trying to retrieve information from querying a specific Asset(Story/Defect) on V1 using the VersionOne.SDK.Java.APIClient. I have been able to retrieve information like ID.Number, Status.Name but not Requests.Custom_SFDCChangeReqID2 under a Story or a Defect.
I check the metadata for:
https://.../Story?xsl=api.xsl
https://.../meta.V1/Defect?xsl=api.xsl
https://.../meta.V1/Request?xsl=api.xsl
And the naming and information looks right.
Here is my code:
IAssetType type = metaModel.getAssetType("Story");
IAttributeDefinition requestCRIDAttribute = type.getAttributeDefinition("Requests.Custom_SFDCChangeReqID2");
IAttributeDefinition idNumberAttribute = type.getAttributeDefinition("ID.Number")
Query query = new Query(type);
query.getSelection().add(requestCRIDAttribute);
query.getSelection().add(idNumberAttribute);
Asset[] results = v1Api.retrieve(query).getAssets();
String RequestCRID= result.getAttribute(requestCRIDAttribute).getValue().toString();
String IdNumber= result.getAttribute(idNumberAttribute).getValue().toString();
At this point, I can get some values for ID.Number but I am not able to retrieving any information for the value Custom_SFDCChangeReqID2.
When I run the restful query to retrieve information using a browser from a server standpoint it works and it does retrieve the information I am looking for. I used this syntax:
https://.../rest-1.v1/Data/Story?sel=Number,ID,Story.Requests.Custom_SFDCChangeReqID2,Story.
Alex: Remember that Results is an array of Asset´s, so I guess you should be accessing the information using something like
String RequestCRID= results[0].getAttribute(requestCRIDAttribute).getValue().toString();
String IdNumber= results[0].getAttribute(idNumberAttribute).getValue().toString();
or Iterate through the array.
Also notice that you have defined:
Asset[] results and not result
Hi thanks for your answer! I completely forgot about representing the loop, I was too focus on the retriving information part, yes I was actually using a loop and yes I created a temporary variable to check what I was getting from the query in the form
Because I was getting the variables one by one so I was only using the first record. My code works after all. It was just that What I was querying didn't contain any information of my use, that's why I was not finding any. Anyway thanks for your comment and observations

Using Baas Parse for Android application but duplicate Table User

I 'm trying to use the Baas Parse for my Android application.
I've followed the quickstart guide with success, so i'have successfully registered a TestObject into my Parse database.
Now, I try to adapt Parse to my needs and to register a User into Parse database with that code:
Parse.initialize(this, "NkThBbZ4gcXQf3s59UGTozpCjKQbECVP5SmuXCkY", "n7a65t3o8fZNAXTOygWIg2L9Kui316yepfgoSdhf");
ParseObject userParse = new ParseObject("User");
userParse.put("username", user.getPseudonyme());
userParse.put("password", user.getPassword());
userParse.saveInBackground();
But it doesn't insert my user into the User table, instead it creates a new table and insert my User in that new User table.
The first User table is a default table created by parse as far as i understand but i don't understand why is it impossible to use it.
The result is that i have 2 Users tables.
Thank you very much for your answers if anyone had the same problem.
Sebastien
The pre-made User table actually has an underscore before it. It is the _User table, not the User table. The underscore is to signify it's a special class that Parse gives you. Use _User instead of User.

Getting all users with a Role in Liferay

I'm new to Liferay development in general, so feel free to point out if I'm going about stuff totally the wrong way.
I'm trying to get a DynamicQuery object of all users within a certain group (I'll use this object to further filter another query I'll do against the message board). The User interface seems to have a roleIds property that I might be able to use, since I already know the roleId I'm interested in. But I can't find the proper way to query if roleIds contains a certain value.
Any ideas on what I want to do?
PS: I would have the exact SQL query I could ask directly, but I'd rather use Liferay's own connection pool, without needing to do some weird ext project thingy.
You don't need a DynamicQuery. These are the methods you are looking for in the classes that Dirk points out:
long[] UserServiceUtil.getRoleUserIds(long roleId)
or
long[] UserLocalServiceUtil.getRoleUserIds(long roleId)
List<User> UserLocalServiceUtil.getRoleUsers(long roleId)
Remember that the methods in the classes XXXLocalServiceUtil are not checking the permissions of the current user.
EDIT: If you are looking for all users with a given role within a given community:
long companyId= _X_; //Perhaps CompanyThreadLocal.getCompanyId() if you don't have it anywhere else?
Role role=RoleLocalServiceUtil.getRole(companyId, "Example Role");
Group group=GroupLocalServiceUtil.getGroup(companyId, "Example Community");
List<UserGroupRole> userGroupRoles = UserGroupRoleLocalServiceUtil.
getUserGroupRolesByGroupAndRole(groupId, role.getRoleId());
for(UserGroupRole userGroupRole:userGroupRoles){
User oneUser=userGroupRole.getUser();
}
The easiest way to access liferays own objects is by using the XXXServiceUtil classes (e.g. RoleServiceUtil.getUserRoles(userId)). Thus you rarely have to deal with any SQL directly. Either the RoleServiceUtil or UserServiceUtil might have what you need.
The roles of an Organizations are stored in the table UserGroupRole, so if you want to get the owner of an Organization you must use the following code:
boolean isOrgOwner =
UserGroupRoleLocalServiceUtil.hasUserGroupRole(
usr.getUserId(),
this.currentOrganization.getGroupId(),
RoleConstants.ORGANIZATION_OWNER);
If you want to retrieve all the Organization Owners of an organization:
List<User> administrators = new LinkedList<>();
List<UserGroupRole> allOrganizationAdministrators =
UserGroupRoleLocalServiceUtil.getUserGroupRolesByGroupAndRole(
this.currentOrganization.getGroupId(), roleId);
for (UserGroupRole userGroupRoleTemp : allOrganizationAdministrators) {
administrators.add(userGroupRoleTemp.getUser());
}
Cheers!

JDO - List of Strings not being retrieved from database

On my User class I have a field that is a list of strings:
#Persistent
private List<String> openIds;
When I create a new user I do this:
User user = new User();
user.openIds.add(openid);
pm.makePersistent(user);
When I break after that last line and look, the openIds contains the openid I put in there.
But, when I later call User user = pm.getObjectById(User.class, id); with the correct id, the openIds field is an empty list.
Anyone know what could cause that?
EDIT: BTW I'm running on the Google App Engine
UPDATE: Looking at the datastore viewer, I can see the openid was correctly stored in the database. So its just not getting it out correctly...
UPDATE 2: Its working fine now. I'm pretty sure I didn't change anything. I think what must have happened is that there was an old version of the user object being pulled from the database. A user object that was put in before I had the code that saves the openid. Once I wiped the database things worked fine.
Not putting that field in the fetch plan ?
Accessing persistent fields directly, rather than going via setters ?
