Grails Pagination in a search query page - grails

I am using following query to filter results in grails.
userList = SecUser.all.findAll{it.merchants.findAll {it.name.toLowerCase()=~ searchString.toLowerCase()}.size()>0}
In this code i have Users and each User have multiple merchants. I extract only that user whose merchant name matches a certain pattern.
Now i further have to filter these users on:
params.max
params.offset
So that i can perform pagination on them. Kindly please help me with this problem.

This has not been tested, but try something like this:
def query = SecUser.where {
merchants.any { merchant ->
merchant.name.equalsIgnoreCase( searchString )
}
}
def userList = query.findAll(max: params.max, offset: params.offset)

Grails Criteria distinct doesn't work

In my app I use createCriteria for getting a list according some criteria.
roleMapping contains user.
I use the following code:
def getTeamOfCompany(def company,def offset=0){
def c = roleMapping.createCriteria()
def result = c.list{
eq('company',company)
eq('isCurrentCompany',true)
firstResult offset
maxResults 10
distinct('user')
user{
order "lastname", "asc"
}
}
return result
}
I use the distinct in order to not get the same user twice, but it didn't work.
If I put projections on the distinct I'll get a list of users instead roleMapping

Dynamic criteria in Grails controller's index action

I am trying to alter the default index action for a Grails controller to enable some basic search criteria.
I have two main issues:
The paginate control at the bottom of the page forgets my search criteria.
How can I use the grails criteria createCriteria().list() operation with variable criteria. In particular, how should I account for things like null (ignored) criteria?
edit: I am adding my controller code:
def index(Integer max) {
session.alarmFilter = params.alarmFilter == null ? (session.alarmFilter == null ? [] : session.alarmFilter) : params.alarmFilter
params.max = Math.min(max ?: 10, 100)
def c = Alarm.createCriteria()
def results = c.list (params) {
if(session?.alarmFilter?.channelInterface != null) {
sqlRestriction("channel_interface_id = ${session.alarmFilter.channelInterface.id}")
}
}
respond results, model:[alarmFilter: session.alarmFilter, alarmInstanceCount: results.totalCount]
}
I'm not fond of saving the search criteria (alarmFilter) in the session since it doesn't really feel like session information. In particular, returning to this page will remember previous search criteria.
Also the if statement is causing an 'SQLException' when the criteria is not selected.

How to use the withCriteria results in a new withCriteria query in Grails?

Consider the first query:
def books = Book.withCriteria {
eq("category", "fiction")
}
How can I use the result of this query in the next query to get all the authors who wrote these books?
I tried:
def authors = Author.withCriteria {
'in'("books", books)
}
but this is not working. What can I do to fix it?
Can't you just query the association directly?
def authors = Author.withCriteria {
books {
eq("category", "fiction")
}
}

Spring Security UI Grails only search/create/edit users for the admin?

I am currently working on a solution in Grails and I have installed the following security plugins:
Spring Security Core
Spring Security UI
I will basically have a solution with the following security structure:
Super Users
Admins(For different business areas)
Users (within the different business areas)
So basically I installed the Spring Security UI in order to allow the various Business Area Admins manage their own areas, they should be able to use the UI in order to allow them to search only for users in thier own area, create users in their own area and edit users only in their own area. However the spring security UI gives people who have access blanket access do anything.
I have added an extra field to the spring security domain model which is "Area", so I was thinking when the admin is searching for users they would only see users in the same area as them, when they create a user they can only do so for their own area and they can only edit users in their own area.
Below is some code that the spring security UI uses to search for the users, can I modify this in order to only return the users that are in the same area as the admin who is currently logged in? or is there a better way?
def userSearch = {
boolean useOffset = params.containsKey('offset')
setIfMissing 'max', 10, 100
setIfMissing 'offset', 0
def hql = new StringBuilder('FROM ').append(lookupUserClassName()).append(' u WHERE 1=1 ')
def queryParams = [:]
def userLookup = SpringSecurityUtils.securityConfig.userLookup
String usernameFieldName = userLookup.usernamePropertyName
for (name in [username: usernameFieldName]) {
if (params[name.key]) {
hql.append " AND LOWER(u.${name.value}) LIKE :${name.key}"
queryParams[name.key] = params[name.key].toLowerCase() + '%'
}
}
String enabledPropertyName = userLookup.enabledPropertyName
String accountExpiredPropertyName = userLookup.accountExpiredPropertyName
String accountLockedPropertyName = userLookup.accountLockedPropertyName
String passwordExpiredPropertyName = userLookup.passwordExpiredPropertyName
for (name in [enabled: enabledPropertyName,
accountExpired: accountExpiredPropertyName,
accountLocked: accountLockedPropertyName,
passwordExpired: passwordExpiredPropertyName]) {
Integer value = params.int(name.key)
if (value) {
hql.append " AND u.${name.value}=:${name.key}"
queryParams[name.key] = value == 1
}
}
int totalCount = lookupUserClass().executeQuery("SELECT COUNT(DISTINCT u) $hql", queryParams)[0]
Integer max = params.int('max')
Integer offset = params.int('offset')
String orderBy = ''
if (params.sort) {
orderBy = " ORDER BY u.$params.sort ${params.order ?: 'ASC'}"
}
def results = lookupUserClass().executeQuery(
"SELECT DISTINCT u $hql $orderBy",
queryParams, [max: max, offset: offset])
def model = [results: results, totalCount: totalCount, searched: true]
// add query params to model for paging
for (name in ['username', 'enabled', 'accountExpired', 'accountLocked',
'passwordExpired', 'sort', 'order']) {
model[name] = params[name]
}
render view: 'search', model: model
}
EDIT....
I believe it may have something to do with the code below:
def results = lookupUserClass().executeQuery(
"SELECT DISTINCT u $hql $orderBy",
queryParams, [max: max, offset: offset])
I think I just need to alter this statement so that it looks for the list of users where the currently logged in users "Area" is equal to the same area as the users. Can anyone please help me with this??
EDIT 2.....
I have now looked into this and have been able to obtain the users Area and now alls I need to do is to modify the query to the database to look for the users that have the same Area as the admin searching. I have tried the following with no luck, can someone please help me with this as I know this must be simple just cant seem to get there :-S
def user = springSecurityService.currentUser
def userArea = user.area
def hql = new StringBuilder('FROM ').append(lookupUserClassName()).append(' u WHERE 1=1 AND u.area = userArea')
EDIT 3.......
Thanks so much half of my problem is solved lol, now just the Ajax piece:
I have tried the below code in order to modify the search for the Ajax function to only return results where the Area of the user is the same as the currently logged in user:
String username = params.term
String usernameFieldName = SpringSecurityUtils.securityConfig.userLookup.usernamePropertyName
def user = springSecurityService.currentUser
setIfMissing 'max', 10, 100
def results = lookupUserClass().executeQuery(
"SELECT DISTINCT u.$usernameFieldName " +
"FROM ${lookupUserClassName()} u " +
"WHERE LOWER(u.$usernameFieldName) LIKE :name AND LOWER(u.area) = :area " +
"ORDER BY u.$usernameFieldName",
[name: "${username.toLowerCase()}%"],
[area: "user.area"],
[max: params.max])
Also tried changing the param as below:
[area: user.area]
The controller is building an HQL query, so you can't just say "WHERE u.area = userArea", you'll need to use a named parameter and put the value in the queryParams map
def user = springSecurityService.currentUser
def hql = new StringBuilder('FROM ').append(lookupUserClassName()).append(
' u WHERE u.area = :userArea ')
def queryParams = [userArea:user.area]
For the second part of the problem (the Ajax bit), I doubt you need the LOWER conversion, and also you need to put all your query parameters into one map (the second map parameter is just for the pagination settings):
def results = lookupUserClass().executeQuery(
"SELECT DISTINCT u.$usernameFieldName " +
"FROM ${lookupUserClassName()} u " +
"WHERE LOWER(u.$usernameFieldName) LIKE :name AND u.area = :area " +
"ORDER BY u.$usernameFieldName",
[name: "${username.toLowerCase()}%", area:user.area],
[max: params.max])
If you really do want the area check to be case-insensitive then leave it as LOWER(u.area) = :area but then you also need to convert the value you are testing against to lower case:
[name: "${username.toLowerCase()}%", area:user.area.toLowerCase()],

Store sql.eachRow() of groovy sql to a List

do you know how to store the result from
sql.eachRow()
of groovy sql to a list? for example def personList = [] ?
example:
sql.eachRow('select lastname from users where id='active')
What I want is to store the result ie. lastnames to a list ie def personlist = [];
I know I can easily do this by namedQuery and I've already done it. But their is some underlying reason about this. Thanks in advance.
def reqdColName = "lastname"
def query = "select $reqdColName from users where id='active'"
Straight option would be to use the rows() method.
def list= Sql.rows(query) //returns groovyrowresult as list
Another option is you could use the executeQuery instead, to get hold of the resultset of the query and thereby get an array/list on it.
def array = Sql.executeQuery(query).getArray(reqdColName)
//If you need as a list
def personList = Arrays.asList(array)
I know that the question has been asked a long time ago, but still, I feel the answer may be of help for someone out there.
def personlist = []
sql = Sql.newInstance(url, username, password, driver)
query = "select $reqdColName from users where id='active'"
sql.eachRow(query)
{
row-> personlist << row.toString()
}
sql.close()
personlist.each{println it} // you can also return the list
def personList = sql.rows("select lastname from users where id='active'")*.lastname
