Good morning the /
I'm working on a Grails project that uses JavaScript to perform the search (both by category and by text) and pagination of items. However, after a few searches by category, the application slows down. In the javascript console it indicates that with each category search, the ajax function responsible for updating the display of items is called several times. Has anyone gone through this or do you have any idea why this happens? The code for the functions involved is below.
Function in Grails control
def searchMyGames() {
def model = [:]
User user = session.user
model.myGroups = Group.findAllByOwner(user)
model.groupsIAdmin = UserGroup.findAllByUserAndAdmin(user,true).group
def threshold = THRESHOLD
def maxInstances = 0
params.order = "desc"
params.sort = "id"
params.max = params.max ? Integer.valueOf(params.max) : threshold
params.offset = params.offset ? Integer.valueOf(params.offset) : 0
model.max = params.max
model.threshold = threshold
log.debug("category: " + params.category)
def myExportedResourcesList = null
if(params.category.equals("-1")){
// exibe os jogos de todas as categorias
myExportedResourcesList = ExportedResource.findAllByTypeAndOwnerAndNameIlike('public', user, "%${params.text}%", params)
maxInstances = ExportedResource.findAllByTypeAndOwnerAndNameIlike('public', user, "%${params.text}%").size()
}
else{
Category c = Category.findById(params.category)
myExportedResourcesList = []
maxInstances = 0
for (r in Resource.findAllByCategory(c)) {
// get all resources belong
myExportedResourcesList.addAll(
ExportedResource.findAllByTypeAndResourceAndOwnerAndNameIlike('public', r, user, "%${params.text}%", params))
maxInstances += ExportedResource.countByTypeAndResourceAndOwnerAndNameIlike('public', r, user, "%${params.text}%")
}
}
model.publicExportedResourcesList = myExportedResourcesList
model.pageCount = Math.ceil(maxInstances / params.max) as int
model.currentPage = (params.offset + threshold) / threshold
model.hasNextPage = params.offset + threshold < model.instanceCount
model.hasPreviousPage = params.offset > 0
model.page = 'myGames'
log.debug("maxInstances final: "+maxInstances)
render view: "_customizedGameCard", model:model
