The page that I'm working on involves a table and datepicker. If I change the value of the date, it should pass the date to the index action and re-query from DB. And display the newly queried data from DB. In other words, datepicker serves as a filter.
I made a change event for the datepicker, if the data is changed this will trigger an ajax call to index. It was able to get the correct data but could not display it properly. Grails returns the whole page. It does not update the page.
Here's my controller:
def index() {
def currentCompany = sessionService.company
def Long countryId = params.countryId ? params.countryId as Long : currentCompany.countryId;
java.text.DateFormat format = new java.text.SimpleDateFormat("dd/MM/yyyy");
Date startDateValue = (params.startDate == null || params.startDate.isEmpty() ) ? null : format.parse(params.startDate)
Date endDateValue = (params.endDate == null || params.endDate.isEmpty() ) ? null : format.parse(params.endDate)
def exchangeRateList = exchangeRateService.getFilteredExchangeRate(countryId, startDateValue , endDateValue)
def currencyList = cacheService.currencies
params.max = 10
params.countryId = countryId
respond ("", model : [
exchangeRateInstanceList : ListUtil.list(exchangeRateList, params),
exchangeRateInstanceCount : exchangeRateList.size(),
currencyInstanceList : currencyList
]);
}
Could you tell me how to trigger call to index action when input test is changed using Grails?
You can use remoteFunction to run action from controller: http://grails.github.io/grails-doc/2.4.4/ref/Tags/remoteFunction.html
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
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)
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: "${username.toLowerCase()}%", area:user.area.toLowerCase()],
I am having problems with the next/prev options not displaying on lists with a Groovy on Grails site. I have modified the automatically generated controller code to limit the items in the list to be items that were created by the user. This works fine, however, if the user has more than 10 items, the next/prev buttons don't show up as expected. Below are the relevant code snippits...
Controller:
def list = {
params.max = Math.min(params.max ? params.int('max') : 10, 100)
def login = authenticationService.getSessionUser().getLogin()
def authUser = AuthenticationUser.findByLogin(login)
def userAcct = User.findByLoginID(authUser)
def userServices = Service.createCriteria()
def results
if (userAcct.role == 'admin') {
results = userServices.list(params) {}
} else {
results = userServices.list(params) {
eq("userID", userAcct)
}
}
[serviceInstanceList: results, serviceInstanceTotal: results.count()]
}
GSP:
<div class="paginateButtons">
<g:paginate total="${serviceInstanceTotal}" />
</div>
When I log in with an account with the "admin' role, the next/prev links appear fine. Non-admin accounts do not display the next/prev links when there are more than 10 items to be listed. Can anyone see what I'm doing wrong?
Your criteria should give you a pagedResultList which has a totalCount. So try
to change the last line of your controller to:
[serviceInstanceList: results, serviceInstanceTotal: results.totalCount]
